Silicone plastic window tape, sealing strip, is a product that seals a thing so that it is not easy to open, and plays the role of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixation. EPDM (EPDM) The rubber strip
is formed by microwave vulcanization process at one time, the surface is smooth and beautiful, has good elasticity and resistance to compression deformation, weather aging resistance, ozone resistance, chemical resistance and a wide temperature range (-50℃~+150℃), etc. Performance, has been widely used in manufacturing industries such as automobile doors, windows and curtain walls. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be certain gaps, which will cause the doors and windows to close tightly. The role of door and window sealing strips is used to eliminate these gaps. However, there are many types of door and window sealing strips, and their uses are also different. I have compiled some relevant information about the types of door and window sealing strips for everyone here. Door and window sealing strips can be divided into major categories in use: glass sealing strips, door leaf and door cover sealing strips and wool strips. The glass sealing strip is used to seal the gap between the glass leaf and the frame. The door leaf sealing strip is used to seal the gap between the door panel and the door frame, and the wool strip is mainly used to seal the gap between the frame and the door. It is said that in the installation process of various doors and windows, the sealing strip is indispensable. The sealing strip plays a role of sealing and waterproofing in plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips have high requirements for materials. First of all, they must have strong stretchability and elasticity, as well as good temperature resistance and aging resistance. At the same time, in order to ensure the close contact between the sealing strip and the profile, the cross-sectional structure of the sealing strip must match the profile of the door and window, which is generally suitable for hanging windows and folding doors and windows. And it does not react with any paint or cleaning agent. Customers do not need to worry about the integrity and aesthetics of doors and windows being damaged. According to the compound structure of the rubber compound, they can be divided into pure rubber sealing strips-composed of a single type of rubber; two composite sealing strips ——Composed of dense rubber and foam sponge rubber, often containing a metal skeleton material in the axial direction inside the dense rubber; three-composite sealing strip——composed of two types of dense rubber (one of which is light-colored) and sponge rubber, usually The dense rubber contains a metal skeleton and reinforcing fibers. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass touch the glass. 3) It has an independent open-cell bubble structure. The appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion The shrinkage changes and changes to enhance the sealing, expansion, and water stop effect of the joint. The wool strip is generally used to install on the sash of the push-type door and window to seal the gap between the frame and the sash. The specifications of the tops can greatly affect the watertight performance of doors and windows, as well as the opening and closing of doors and windows. If the size of the top is too large, or the vertical hair is too high, it will be very difficult to assemble, and after it is assembled, the resistance of doors and windows will increase when they move. If the fire size is too small, or the vertical hair is too low, brackets are prone to occur in doors and windows, which reduces the airtightness of doors and windows. There are generally two types of tops that have undergone silicification treatment and those that have not been silicified. Generally, the treatment effect will be better. Quality tops have the following characteristics: there are no obvious defects in appearance, the surface is straight, the bottom plate and vertical hair are relatively smooth, there is no bending phenomenon, and there are no pits and other problems on the bottom plate, and it meets the size requirements. In fact, there are many places in our lives that cannot be separated from this product, because its use effect is very good, friends who don’t know can join me to take a look at the characteristics of EPDM sealing strip. Third, ozone resistance The ozone resistance of the product is very good, and it can be completely exposed to the air to work, so that the superiority of the product is more prominent, and the anti-ultraviolet radiation effect of the EPDM sealing strip is also very good. Yes, but also has excellent physical and mechanical properties, so it is often used to make airplanes, trains, cars, and so on. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass touch the glass. 3) It has an independent open-cell bubble structure. The appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion The shrinkage changes and changes to enhance the sealing, expansion, and water stop effect of the joint. This technology is recognized by the world as a good process for producing extruded products. The characteristic of microwave heating is that heat is directly generated in the object to be heated, instead of being input from the outside as usual. This not only generates heat quickly, but also distributes it uniformly, which is beneficial Improve product quality and greatly shorten the heating time. Hot air vulcanization sealing strip: Hot air vulcanization has developed to strong wind type vulcanization, that is, high temperature, high-speed hot air vulcanization (Tmax: 450°C and Vmax: 60m/s) is also used. The effect of flame pretreatment can be achieved, and the safety is greatly improved. The main function of silicone plastic window and door and window is to seal, how to strengthen the sealing
