What is styrofoam?

Styrofoam, the full name of one-component polyurethane vinegar foam caulk, also known as foaming agent, PU caulk, etc., is a one-component moisture-curing, multi-purpose polyurethane vinegar foaming material. Its main components are black material, white material composed of polyurethane vinegar prepolymer dimethyl ether and propylene butane, when the material is sprayed out of the aerosol can, the polyurethane vinegar prepolymer will expand rapidly and solidify with the moisture in the air or environment to form foam.
Second, the specification classification of styrofoam

1. Pistol

It is necessary to use a special foaming glue gun for gluing, which has a higher pressure, larger foaming volume and more delicate bubble holes than the tubular type.

2. Tubular type

The equipped disposable pipe is used for gluing, which is convenient for construction and suitable for places where the amount of household plugging and leakage prevention is not large
3. Advantages of styrofoam

1. Low cost

2. Easy to use and easy to use

3. Excellent waterproof performance

4. It is not suitable for combustion, and the safety factor is high
Fourth, the use of styrofoam

1. Door and window installation

Caulking sealing, fixing and bonding between doors, windows and walls.

2. Advertising model

Fabrication of models and sand tables, and repair of display panels.

3. Sound insulation and sound reduction

Filling gaps in the decoration of speech rooms and broadcasting studios can play a role in sound insulation and sound reduction.
4. Gardening

Flower arrangement, gardening and landscaping, light and beautiful.

5. Daily maintenance

Repair of holes, crevices, wall tiles, floor tiles, floors.

6. Waterproof plugging

Repair and plug leaks in water pipes and sewers.
How to use tubular styrofoam

1. Install the tube

When using styrofoam, it is necessary to install a special tube to ensure that the glue can be squeezed smoothly. First, screw the tube into the threaded hole at the top of the drum and tighten the fixing nut to prevent leakage or loss of styrofoam. Make sure the connection of the tube is firm and reliable so that the tube does not slip.

2. Extruded styrofoam

When the tube is installed, you need to adjust the knob first to control the flow rate and flow of the glue. Place the tube 2-3 cm above the material to be bonded and gently press down on the pressure lever to squeeze out the styrofoam juice. When using, it is necessary to ensure that the force is balanced, stable and soft, and avoid glue loss or clogging.

3. Maintain the tube

After use, clean the glue immediately. Use a soft cloth to wipe the surface of the tube, clean dirt and residual glue, and scrub the inside of the tube with a brush to prevent clogging and affecting the next use. At the same time, it is necessary to check whether the condition of the tube is normal, and if it is damaged or aged, it should be replaced in time.

7. Precautions

1. Precautions for storage

The normal use temperature of styrofoam tank is +5~+40°C, and the optimal use temperature is +18~+25°C. In the case of low temperature, it is recommended to place this product at a constant temperature of +25~+30° for 30 minutes before using it to ensure its best performance. The temperature resistance range of cured foam is -35°C~+80C.
2. Precautions for use

(1) Styrofoam is a moisture-curing foam, which should be sprayed on a humid surface when used, the greater the humidity, the faster the curing. Uncured foam can be cleaned with a cleaning agent, and the cured foam should be removed by mechanical methods (sanding or cutting), and after the spray gun is used, clean it with a special cleaning agent.

(2) When replacing the tank, shake the new tank well (shake it at least 20 times) to remove the empty tank, and quickly replace the new tank to prevent the gun connection from curing.

(3) The flow control valve and trigger of the spray gun can control the size of the foam flow, and the flow valve will be closed in a clockwise direction when the spray stops.
3. Safety precautions

(1) Uncured foam is sticky to skin and clothing, so do not touch it.

(2) Do not go near fire sources and expose to the sun.

(3) The storage environment needs to be kept dry, not upside down or flat.

(4) Pay attention to the expiration date.

(5) Do not litter empty cans after use, especially styrofoam cans that have been partially used but have not been used up.

(6) Construction personnel should wear work gloves, work clothes and goggles during construction, and do not smoke at the same time

Condensed type
broadcast
edit
It is the most common kind of room temperature vulcanized silicone rubber, and its raw rubber is usually hydroxyl terminated polysiloxane, and then combined with other compounding agents and catalysts to form a rubber compound, the viscosity of this rubber material can range from 100 centime to 1 million centi.
Vulcanization method
The vulcanization reaction of condensed one-component room-temperature vulcanized silicone rubber is initiated by moisture in the air.
The vulcanization reaction of condensed two-component room-temperature vulcanized silicone rubber is not initiated by moisture in the air, but by a catalyst. Usually the silica rubber, filler, and cross-chain agent are packaged as one component, and the catalyst is packaged separately as another component, or other combinations are used, but the catalyst and the cross-chain agent must be packaged separately. Regardless of the type of packaging, curing only begins when the two components are completely mixed together.
The vulcanization reaction of addition two-component room temperature vulcanized silicone rubber is accomplished by the addition reaction of silicon-hydrogen bonds and silica vinyl in the presence of a platinum metal catalyst.
Crosslinkers
Condensed silicone rubber The commonly used crosslinker is ethyl orthosilicate and the catalyst is dibutyltin dilaurate. and add appropriate fillers and additives depending on the nature of the desired end product. Over the years, many countries have banned the addition of dibutyltin in food bags and plasma bags due to the fact that tin dibutyl dilaurate is a moderately toxic substance, and has basically been replaced by octyltin with low toxicity.
The crosslinker of additionally molded silicone rubber is generally an oligomeric hydrosilicon. Catalysis is performed with a Karst catalyst or chloroplatinic acid.
Vulcanization time
The curing time of two-component condensed room-temperature vulcanized silicone rubber depends mainly on the type of catalyst, the amount used, and the temperature. The more catalyst is used, the faster the vulcanization and the shorter the shelving time. At room temperature, the shelving time is generally a few hours, and if you want to extend the shelving time of the compound, you can use the cooling method. Two-component condensed room temperature vulcanized silicon rafter takes about a day to reach full cure at room temperature, but only 1 hour at 150°C. The cohesive effect by using the accelerator γ-aminopropyltriethoxysilane can significantly increase its curing speed.
performance
Two-component room temperature vulcanized silicone rubber can maintain elasticity for a long time in the temperature range of 65~250 °C, and has excellent electrical properties and chemical stability, can resist water, ozone, weather aging, coupled with simple use, strong process applicability, therefore, can play a protective role in moisture (anti-corrosion, shockproof, etc.). It is possible to improve performance and stabilize parameters. Two-component room-temperature vulcanized silicone rubber is particularly suitable for deep potting materials and has a fast vulcanization time, which is superior to one-component room-temperature vulcanized silicone rubber. [1]
apply
Two-component room temperature vulcanized silicone rubber has excellent anti-stick properties after vulcanization, and the shrinkage rate is very small during vulcanization, so it is suitable for manufacturing soft molds, in addition, the high simulation performance of two-component room temperature vulcanized silicone rubber can be used to reproduce a variety of exquisite patterns. For example, it can be used to reproduce ancient bronzes in the reproduction of cultural relics, and can be used to copy the skin patterns of snakes, pythons, crocodiles and pangolins in the production of artificial leather. [2]
Precautions
The binder, crosslinker and catalyst are first weighed separately and then mixed in proportion.
Usually the two components should be supplied in different colors, so that the mixing of the two components can be visually observed, and the mixing process should be handled with care to minimize the amount of entrapped gas. After the rubber is mixed (uniform color), the bubbles can be removed by standing or depressurizing (vacuum degree 700 mm Hg), and after all the bubbles are discharged, they can be vulcanized into silicon eraser at room temperature or at a specified temperature for a certain time.
Product category:

Methyl biphenyl room temperature vulcanized silicone rubber
In addition to the excellent performance of methyl room temperature vulcanized silicone rubber, methyl biphenyl room temperature vulcanized silicone rubber has a wider service temperature range (-100~250 °C) than methyl room temperature vulcanized silicone rubber. Low phenyl room temperature vulcanized silicone rubber (108-1) with phenyl content of 2.5~5% can maintain elasticity at low temperature of -120 °C, and is the best variety of silicone rubber with low temperature performance. Room temperature glue (108-2) with phenyl content of 10~20% has good radiation resistance, ablation resistance and self-extinguishing properties, if a certain amount of heat-resistant additives such as Fe2O3 are added to it, it can improve the thermal aging performance, and is suitable for use at high temperatures above 250 °C or as ablation-resistant putty coating and encapsulation materials.
Methylphenyl room temperature adhesives, like other room temperature adhesives, can be used for dipping, impressioning, and delamination. If you want to increase the adhesion with other materials, you must use the material before the surface treatment, the surface treatment of the material is as follows: clean the surface of the material with acetone solvent 1~2 times, then treat it with surface agent 1~2 times, bake it in the oven at 60 °C for several minutes, and then form a layer of film with few sticky hands on the surface of the material, and then it can be glued.
Methyl block room temperature vulcanized silicone rubber
Methyl block room temperature vulcanized silicone rubber is a modified variety of methyl room temperature vulcanized silicone rubber, which is a copolymer of polydimethylsiloxane (107 rubber) and methyltriethoxysilane oligomer (molecular weight 3~5) with a hydroxyl head. Under the catalysis of dibutyltin dilaurate, the hydroxyl group in polydimethylsiloxane and the ethoxy group in polymethyltriethoxysilane are condensed to form a polymer with a three-way structure, and the vulcanized ejectable body has higher mechanical strength and adhesion than methyl room temperature vulcanized silicone rubber, and can be used for a long time in a temperature range of 70~200 °C.

]]> what is the diffrents of acrylic sealant bettwen silicone sealant https://oksizy.com/2024/12/13/what-is-the-diffrents-of-acrylic-sealant-bettwen-silicone-sealant/ Fri, 13 Dec 2024 01:30:06 +0000 https://oksizy.com/?p=516 Acrylic-based sealants: application details and main features
Acrylic-based sealants are a common choice for home renovation and construction projects and are highly adaptable. These sealants are preferred for their superior flexibility and adhesion to a wide range of surfaces and applications. Used to fill spaces around windows, doors, and other fixtures, acrylic-based sealants provide a stable, long-lasting bond that won’t fade over time.

One of the main advantages of acrylic sealants is their ease of use. It can be applied evenly and smoothly with a caulking gun, and it’s simple to clean with water before hardening. As a result, they are the best choice for experienced contractors and do-it-yourselfers. In addition, the brushable acrylic sealant allows the sealing area to smoothly blend with the surrounding surface for a polishing effect.

Another important feature of acrylic sealants is that they are environmentally friendly. Acrylic sealants are safer to use indoors because they contain fewer volatile organic compounds (VOCs) than some other types of sealants, while some other types of sealants release strong odors and potentially harmful fumes. To ensure the longevity and durability of the sealant, the sealant also has UV resistance, which helps prevent the sealant from cracking and aging when exposed to sunlight.

While acrylic sealants have many advantages, it’s also important to understand their limitations and specific uses. They’re ideal for use indoors and in places with little exposure to nature or water. For exterior applications or areas with high humidity, it is critical to choose a sealant that can survive in harsh environments. Knowing these details, you’ll be able to choose the best sealant for your project and be guaranteed the best results.
Features and properties of sealants
Acrylic sealant is an acrylic resin-based ingredient that is used to waterproof and seal a variety of seams and joints. Beginners should use an acrylic sealant because it is very easy to handle and does not freeze for a long time to hold the seams in place. The product can be painted or plastered after drying, and has a certain elasticity and vibration adaptability.
Fields of application
The sealant does not contain solvents or other harmful substances and is an ideal material for interior decoration. Even in enclosed spaces, it can be used without wearing personal protective equipment. The most common application of acrylic sealants is at the joints between logs and wood. Acrylic sealants provide good adhesion to porous building materials and are best suited for wood and concrete.
The difference between acrylic sealant and silicone
Silica gel and acrylic compounds differ in performance and application characteristics:

The acrylic sealant can be treated with seams after hardening. Any color of acrylic, latex, and other water paints can be easily stained. If necessary, individual seams can be repaired and partially renewed. Paint doesn’t turn silicone or fade quickly.
Acrylic sealants can be mechanically treated: grinding, drilling. Silicone has this effect and can be completely separated, damaging the joints.
Acrylic is an order of magnitude worse moisture resistance than silicone. The basis of acrylic sealants is an aqueous dispersion of acrylates so they will still dissolve. Silicone is a rubber-like waterproof material.
Acrylic sealants are also not as good as silicone sealants when it comes to elasticity. Silicone sealants are more malleable, have less shrinkage, and have a longer stretch distance without causing damage.
Acrylic is permeable to water vapor, while silicone is impermeable. Thanks to this property, the acrylic compound does not disrupt the indoor microclimate and does not lead to the accumulation of steam and moisture.
Acrylates have excellent adhesion to porous building materials and are best suited for wood, concrete, etc. Before sealing, sandpaper or other methods should be used to treat the smooth ground to improve the quality of the bonding.
The color scheme of the acrylic component is more abundant. If you want, you can choose the appropriate remedy for any shade, including different woody species. Silicone agents are produced in a limited range (typically white, black, gray, and red).
Silicone is very durable – it can last up to 20 years. Acrylics start aging earlier because they become more noticeable over time.
The price of acrylic preparations is always lower than the price of silicone. The average difference is 30-50%, which is very important for many users.
The environmental friendliness of acrylic is beyond doubt. Such funds are completely safe for people and the environment. Silicone sealants can produce an unpleasant odor on an acidic basis, so they should not be used regularly.

]]> The difference between neutral and acidic glass glue https://oksizy.com/2024/12/12/the-difference-between-neutral-and-acidic-glass-glue/ Thu, 12 Dec 2024 06:09:33 +0000 https://oksizy.com/?p=509
  • The performance of glass glue is different, and the usage is different

    •  

    In fact, the glass glue commonly used in home decoration is divided into two kinds according to its performance: neutral glass glue and acid glass glue. Because many people do not understand the properties of glass glue, they are easy to use neutral glass glue and acid glass glue. A person who has been engaged in the sales of glass glue for a long time told reporters that this is the main problem of using glass glue in home decoration. Customers often don’t say the use, just say “two bottles”, in fact, the gap is quite large.

     

    The places where glass glue is generally used in home decoration are: the dumb place on the back of the wood line, sanitary ware, toilet, makeup mirror in the bathroom, the gap between the sink and the wall, etc., these places should use glass glue with different properties. The adhesive of neutral glass adhesive is relatively weak, and it is generally used in the back of the bathroom mirror where there is no need for strong adhesion. Neutral glass glue is used more in home decoration, mainly because it will not corrode objects, while acid glass glue is generally used in the dumb part of the back of the wood line, and the adhesion is very strong.

     

    1. Pay attention to mildew prevention when using glass glue

     

    There is another important point in the use of glass glue: it must be mildew-proof. For example, many glass glue are used in the bathroom, and the bathroom is already very humid and easy to mold, so the glass glue must be mildew-proof. Generally, the glass glue bottle will be explained, be sure to see. In addition, some glass glue of poor quality does not have such a function at all, so you must recognize it when buying.

     

    1. Buy glass glue don’t figure cheap quality is very important

     

    At present, the quality of glass glue on the market is uneven, and the simpler way is to judge its quality by brand and price. When purchasing, try to choose brand glass glue, they are guaranteed in quality, especially on the packaging of these brand glass glue There will be detailed product descriptions, so that buyers can distinguish the performance.

    Second, the difference between the neutral and acidic properties of glass glue

    1. Acid glass glue

     

    Acid glass glue is suitable for sealing, blocking, leakage prevention and weatherproof use, both indoor and outdoor (indoor effect is better), anti-seepage and leak-proof effect is remarkable. Bonding a wide range of automotive interiors, including metals, fabrics, and agricultural production system fabrics and plastics. Bonding gaskets on heating and cooling equipment. Addition of screw-free ribs, nameplates, lacquer and plastic materials to the metal surface. Seal the windows on the oven door, the flue on the gas appliance, the pipe joint, and the passage door. Provide leak-proof gaskets for gearboxes, compressors, and pumps that are ready for immediate forming. Sealing of the ship’s hold as well as the window. Sealing of glass windows in trailers and truck cabs. Bonding and sealing of equipment components. Formation of an anti-wear coating. Inlay and fill thin sheet metal laminates, pipe networks and equipment enclosures.

     

    1. Neutral glass glue

     

    Neutral weather-resistant adhesive is suitable for weather-resistant sealing of various curtain walls, especially recommended for weather-resistant sealing of glass curtain walls, aluminum-plastic panel curtain walls, and stone dry hanging; Seam sealing between metal, glass, aluminum, ceramic tiles, agricultural production system glass, and coated glass; Sealing joints on concrete, cement, masonry, rock, marble, steel, wood, aluminium and painted aluminum. In most cases, there is no need to use a primer.

     

    Related Concepts:

     

    colloid

            Colloid, also known as colloidal dispersion, is a relatively homogeneous mixture, in which the colloid contains two different states of substances, one dispersed phase and the other continuous phase. A part of the dispersed matter is composed of tiny particles or droplets, and the dispersion system with a diameter of 1~100nm is colloidal; Colloids are a kind of dispersion systems with a diameter of dispersed particles between the coarse dispersion system and the solution, which is a highly dispersed multiphase heterogeneous system. The relevant knowledge of colloids can also be applied in wastewater treatment, and some pollutants in wastewater exist in the form of colloids, so many high-level sewage treatment equipment aims to study how to quickly and efficiently remove pollutants in the form of colloids in wastewater. Colloids don’t have to be gelatinous and they don’t have to be liquids. Such as: iron hydroxide colloid, clouds, fog, etc.

It is a polyurethane elastomeric sealing foam that relies on moisture curing. Styrofoam is composed of polyurethane prepolymer, foaming agent, catalyst, cross-linking agent, etc. filled into a high-pressure iron can, and filled with propane and other gases. It is divided into two types: gun type and tube type, the gun type is required to use a special polyurethane foam gun, and the tube type is equipped with a disposable hose.

     

    Introduction of styrofoam

    Styrofoam is a kind of filling, sealing and bonding mainly used for filling, sealing and bonding at the edge joints of building doors and windows, expansion joints and holes of components. It is a polyurethane elastic sealing foam material that relies on moisture curing. It is divided into two types: gun type and tube type, the gun type is required to use a special polyurethane foam gun, and the tube type is equipped with a disposable hose. It is a one-component, moisture-curing, multi-purpose polyurethane foam-filled elastomeric sealant. Styrofoam is a special polyurethane product that fills polyurethane prepolymers, blowing agents, catalysts and other components in pressure-resistant aerosol cans.

    Foaming principle

    When the material is ejected from the aerosol can, the foam-like polyurethane material expands rapidly and solidifies with the air or moisture in the substrate it comes into contact with to form a foam. The cured styrofoam foam has a variety of effects such as caulking, bonding, sealing, heat insulation, sound absorption, etc., and is an environmentally friendly, energy-saving, easy-to-use building material, which can be used for sealing and plugging, filling in the gaps, fixing and bonding, thermal insulation and sound insulation, especially suitable for sealing and plugging and waterproofing between plastic steel or aluminum alloy doors and windows and walls

    The use and steps of tubular styrofoam

    1. Same as the second step of the gun type.
    2. Then take the disposable hose and screw it clockwise.
    3. Make sure that the tank is placed above, the foaming gun is below the tank, aim at the bottom or inside of the part to be filled, gently pull the trigger, and start construction.
    4. Spray from bottom to top, and the injection volume can be 80% of the required filling volume (the filling volume of the tube type is 2/3)

    Use tips

    Pay attention to the travel speed when spraying, usually the injection volume is 2/3 of the required filling volume. Vertical gaps should be filled from bottom to top; When filling gaps such as those in the ceiling, uncured foam may fall due to gravity, so it is recommended to provide proper support just after filling and wait for the foam to solidify and bond to the seam wall before withdrawing the support. In about 10 minutes, the foam will be debonded, and after 60 minutes, it can be cut. Use a knife to cut off the excess foam and apply the surface with cement mortar, paint or silicone.

    Storage method

    It is strictly forbidden to store in a dry, cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C.

    Main uses:

    Door and window installation: caulk sealing, fixed bonding between doors and windows and walls.

    Advertising model: production of models and sand tables, repair of display boards.

    Sound insulation and sound reduction: filling the gaps in the decoration of the language room and broadcasting room can play a role in sound insulation and sound reduction.

    Gardening: flower arrangement, gardening, light and beautiful.

    Daily maintenance: repair of holes, gaps, wall tiles, floor tiles, floors.

    Waterproof plugging: repair and plugging of water pipes, sewers and other loopholes.

    Precautions

    Precautions for storage

    The normal use temperature of styrofoam tank is +5~+40°C, and the optimal use temperature is +18~+25°C. In the case of low temperature, it is recommended to place this product at a constant temperature of +25~+30°C for 30 minutes before using it to ensure its best performance. The temperature resistance range of cured foam is -35°C~+80°C.

    Precautions for use

    1. Styrofoam is a moisture-curing foam, which should be sprayed on a moist surface when used, the greater the humidity, the faster the curing. Uncured foam can be cleaned with a cleaning agent, while cured foam should be removed mechanically (sanding or cutting). The cured foam will turn yellow when exposed to ultraviolet light, and it is recommended to coat the cured foam surface with other materials (cement mortar, paint, etc.). After the spray gun is used, please clean it with a special cleaning agent immediately.
    2. When replacing the tank, shake the new tank well (at least 20 times), remove the empty tank, and quickly replace the new tank to prevent the gun connection from curing.
    3. The flow control valve and trigger of the spray gun can control the size of the foam flow. When the injection stops, the flow valve is closed in a clockwise direction.

    Safety Precautions

    The uncured foam is sticky to the skin and clothes, do not touch the skin and clothes when using, the pressure in the styrofoam can is 5-6kg/cm2 (25 °C), the temperature should not exceed 50 °C during storage and transportation, in case of tank explosion, the styrofoam can should be avoided from direct sunlight, it is strictly forbidden for children to touch, the empty cans after use, especially the styrofoam cans that are partially used and have not been used up, should not be thrown away, and it is forbidden to burn or puncture the empty cans. Keep away from open flames and do not come into contact with flammable and explosive materials. The construction site should have ventilation conditions, and construction personnel should wear work gloves, work clothes and goggles during construction, and do not smoke at the same time. In case the foam gets in contact with your eyes, rinse with water before going to the hospital. In case of contact with skin, rinse with water and soap.

    The difference between styrofoam and blowing agent

    Styrofoam is a special polyurethane product that fills polyurethane prepolymers, foaming agents, catalysts and other components in pressure-resistant aerosol cans. When the material is ejected from the aerosol can, the foam-like polyurethane material expands rapidly and solidifies with the air or moisture in the substrate it comes into contact with to form a foam. The cured foam has a variety of effects such as caulking, bonding, sealing, heat insulation, sound absorption, etc., and is an environmentally friendly, energy-saving, and easy-to-use building material. It can be used for sealing and plugging, filling in the gaps, fixing and bonding, thermal insulation and sound insulation, especially suitable for sealing and plugging and waterproofing between plastic steel or aluminum alloy doors and windows and walls. Styrofoam is also required for the installation of finished door covers

It is divided into two types: gun type and tube type, the gun type is required to use a special polyurethane foam gun, and the tube type is equipped with a disposable hose.

     

    Introduction of styrofoam

    Styrofoam is a kind of filling, sealing and bonding mainly used for filling, sealing and bonding at the edge joints of building doors and windows, expansion joints and holes of components. It is a polyurethane elastic sealing foam material that relies on moisture curing. It is divided into two types: gun type and tube type, the gun type is required to use a special polyurethane foam gun, and the tube type is equipped with a disposable hose. It is a one-component, moisture-curing, multi-purpose polyurethane foam-filled elastomeric sealant. Styrofoam is a special polyurethane product that fills polyurethane prepolymers, blowing agents, catalysts and other components in pressure-resistant aerosol cans.

    Foaming principle

    When the material is ejected from the aerosol can, the foam-like polyurethane material expands rapidly and solidifies with the air or moisture in the substrate it comes into contact with to form a foam. The cured styrofoam foam has a variety of effects such as caulking, bonding, sealing, heat insulation, sound absorption, etc., and is an environmentally friendly, energy-saving, easy-to-use building material, which can be used for sealing and plugging, filling in the gaps, fixing and bonding, thermal insulation and sound insulation, especially suitable for sealing and plugging and waterproofing between plastic steel or aluminum alloy doors and windows and walls

    The use and steps of tubular styrofoam

    1. Same as the second step of the gun type.
    2. Then take the disposable hose and screw it clockwise.
    3. Make sure that the tank is placed above, the foaming gun is below the tank, aim at the bottom or inside of the part to be filled, gently pull the trigger, and start construction.
    4. Spray from bottom to top, and the injection volume can be 80% of the required filling volume (the filling volume of the tube type is 2/3)

    Use tips

    Pay attention to the travel speed when spraying, usually the injection volume is 2/3 of the required filling volume. Vertical gaps should be filled from bottom to top; When filling gaps such as those in the ceiling, uncured foam may fall due to gravity, so it is recommended to provide proper support just after filling and wait for the foam to solidify and bond to the seam wall before withdrawing the support. In about 10 minutes, the foam will be debonded, and after 60 minutes, it can be cut. Use a knife to cut off the excess foam and apply the surface with cement mortar, paint or silicone.

    Storage method

    It is strictly forbidden to store in a dry, cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C.

    Main uses:

    Door and window installation: caulk sealing, fixed bonding between doors and windows and walls.

    Advertising model: production of models and sand tables, repair of display boards.

    Sound insulation and sound reduction: filling the gaps in the decoration of the language room and broadcasting room can play a role in sound insulation and sound reduction.

    Gardening: flower arrangement, gardening, light and beautiful.

    Daily maintenance: repair of holes, gaps, wall tiles, floor tiles, floors.

    Waterproof plugging: repair and plugging of water pipes, sewers and other loopholes.

    1. Uses. There is a big difference between the uses of these two kinds of glass glue, and when using it, we must choose the right glass glue according to the needs in order to play its role. Pickled glass adhesive is suitable for sealing, blocking, leakage prevention and weatherproof use, both indoor and outdoor (indoor effect is better), anti-seepage and leak-proof effect is remarkable. Neutral weather-resistant adhesive glass adhesive is suitable for all kinds of curtain wall weather-resistant sealing, especially recommended for glass curtain wall, aluminum-plastic panel curtain wall, stone dry hanging weather-resistant sealing, in addition, metal, glass, aluminum, ceramic tile, plexiglass, coated glass between the joint sealing is also the use of neutral glass glue.

     

    1. Nature. The different properties of glass glue will make its performance different, acid glass glue is also called deacidified silicone glass glue, acid glass glue absorbs moisture in the air and releases acetic acid gas in the curing process. Dealcoholized silicone glass glue is neutral glass glue, which absorbs moisture in the air and releases ethanol gas during the curing process.

     

    1. Curing speed. In terms of curing speed, acid glass glue has more advantages, neutral glass has strong adhesion and can firmly stick to objects, but its ductility is weak, and its glue curing speed is slow. Acid glass glue cures quickly and is corrosive to metals.
    2. Price. In terms of price, many factors such as brand and region will affect the price of glass glue, but on the basis of these two glass glues, the price of neutral glass glue is undoubtedly higher than that of acid glass glue, and the impact of neutral glass glue on the adhesive material is small, and the cost of acid glue is low. If there are regulations or environmental restrictions in the project, remember not to confuse them to avoid affecting the quality of the project.
