<p> Heihe Aihui Sealant Cold Grout Sealant Brand recommends classified construction sealant: for simple wall joints. Welcome to Heihe Aihui Liquid Sealant. This type of sealant includes liquid polymer that can be formed through vulcanization. They have the ability to withstand repeated seam deformation. The service life of liquid sealant is generally 15 ~. This type of sealant has high adhesion and shear strength, and has good properties at room temperature. Its disadvantages are high, usually under primer, two-component sealant is not convenient to mix on-site, temperature and humidity when curing. Preferential classification: This type of sealant is divided into levels according to displacement capacity and modulus. Used for waterproofing, weather-resistant sealing and decoration of natural stone joint structures such as granite and marble. Suitable sealants include neutral silicone sealants, polyurethane, polysulfide, and acrylic sealants. After the initial setting of Shandong glue, the nozzle can be filled without fluidity. The average method to buy sealant mainly depends on several properties: breaking strength (pulling force / cross-sectional area); adhesive strength (pulling force / bonding area, except for the substrate); elongation at break (pulling break Length (original length); anti-aging ability; appearance (mattness, particles, bubbles); shape retention (no drawing, no sag on the facade); shelf life; curing time. Heihe Aihui Sealant Cold Filling Sealant Brand recommends that the glue should be adjusted according to the formula and operation sequence. Professional is the king of plastic glue can not be ignored believe that many people do not pay much attention to the maintenance and maintenance of vehicle glue. The master said, don't underestimate these plastic edges, they not only decorate the body, but also play an important role in sealing the compartment. Therefore, when these sealants are aged or even cracked, they will seriously affect the waterproof and sound insulation performance of your car. Wholesaler </ p> <p>

</ p> <p> Heihe Aihui Sealant Cold Filling Sealant Brand recommends blowing the foam sealant with a hair dryer to soften and remove it. Of course, use caution when using foam glass sealant to avoid unnecessary trouble. Polyurethane sealants are widely used in building, road and highway as caulking seal materials, as well as sealing of automobiles, glass installation, electronic filling, submarine and rocket. Sealant is a kind of widely used adhesive. It mainly refers to those materials that can follow the shape of the sealing surface and have the characteristics of not easy to flow. It has a certain cohesiveness and has a good sealing effect. So how much do you know about the requirements for the use of sealants? Let's analyze them in detail: Usually the requirements for the use of building sealants are mainly environmental factors. Drying and dehumidifying concrete cracks during filling and cracking (when cracks or winter ground temperature is lower than 5 ℃, but construction is not recommended before and after rain): hot air spray removes water from the road surface to form a dry joint surface; other aspects The heat generated by the hot air spray can instantly heat the pavement asphalt, soften the pavement asphalt concrete structure surface layer, make the hot-melt joint material and the pavement form a thermal effect, and increase the adhesion between the pavement and the material. Pass the next process. Heihe Aihui should pay attention to whether the cracks are handled as required, whether the nozzle is firmly bonded, whether the mixing ratio is accurate, and whether the mixing is uniform or not, which determines the quality of the filling effect. When the filling nozzle is buried at the ranking level (side) or inverted (bottom), you can apply 502 instant adhesive on the base of the nozzle and fix it temporarily by finger pressing for 20 seconds; then apply LYJGN? , So that the glue will bury the glue nozzle base more than 5mm, to meet the requirements of pressure injection. (When the top nozzle is buried, 502 glue is not required). Resin-based sealants based on resin. Commonly used resins are epoxy resins, unsaturated polyester resins, phenolic resins, polyacrylic resins, and polyvinyl chloride resins. Property Jiuquan products are mostly emulsion type, and solvent-based products are rare. Emulsion-type products have low cost and can be used for interfaces. They are solidified by evaporation of moisture. They should not be exposed to rain before curing. They are mainly used for sealing joints in buildings. Emulsion-type acrylate sealant is solvent-free. After curing, it can be resistant to water, aging and oil. It has sufficient elongation and adhesion. In recent years, the appearance of silicone-modified acrylic sealants has better performance, especially the water resistance and aging resistance are much higher than ordinary acrylic sealants. Heihe Aihui Sealant Cold Grouting Adhesive Brand recommends that the cold grouting adhesive is mainly used for cement concrete roads, airports, bridges, factory floors, roofing and other expansion joints, settlement joints, cutting joints, etc., and is also suitable for cement concrete substrates. Irregular cracks are poured, filled and repaired. The weather-resistant sealants in the sales department mainly include silicone sealants, neoprene sealants, and polysulfide sealants. The compatibility between them is poor, and they should not be mixed or used together. Weather-resistant sealants are mainly used for external building seals. Resistance to atmospheric changes, ultraviolet rays, and aging are its main considerations. Property rights </ p> <p>

</ p> <p> Heihe Aihui Sealant Cold Grouting Adhesive Brand recommends classified paste sealants according to their morphology: This type of sealant is a low-level sealant that usually uses 3 main materials, oil and resin polybutene asphalt. The fixed glass commonly used for sealing small windows has a large joint movement deformation of + 5% or -5%. The use period is generally 2 years. The homepage recommends that if the silicone sealant can not meet the above requirements, Heihe Aihui potting compound, then its sealed insulating glass is likely to fail during the use period, resulting in failure and loss of energy saving effect. Oil-based sealants are strongly recommended to be based on oil. Commonly used oils include various vegetable oils such as linseed oil, castor oil and tung oil, and animal oils (such as fish oil). Step: Glue Fill the glue in the processed gap. You can use the filling machine, glue, I have a plastic mouth, kettle and other methods. (Cracks with a width of less than 3 mm must be expanded with a seam expansion machine before being filled with glue. Heihe Aihui two-component polyurethane road jointing paste. The width and depth of the cracks after expansion are 6-8 mm. The reason for the seam is because the width of the crack is too small, the inherent surface of the potting compound, Heihe Aihui two-component polyurethane potting compound, can not achieve the self-leveling of the colloid, and can not smoothly enter the crack. There are many types of glue: high temperature, ordinary, low temperature and severe cold. These types are suitable for areas with outdoor temperature of 0 ℃, -10 ℃, -20 ℃, -30 ℃. Customers can choose according to their own needs. Choose the right product, special temperature or requirements can also be customized. Casting brilliant purchase sealant mainly depends on several properties: breaking strength (pulling force / cross-sectional area); adhesive strength (pulling force / bonding area, except for the substrate); elongation at break (pulling off Length (original length); anti-aging ability; appearance (mattness, particles, bubbles); shape retention (no drawing, no sag on the facade); shelf life; curing time. Precautions in this paragraph Surface preparation The construction surface should be clean, dry, and free of oil, grease, and surface contamination such as release agents, curing films, and hydrophobic agents. Thoroughly remove all loose particles and dust. Use Primer 3 on concrete and porous surfaces. </ p>
