Hollow special-shaped silicone strip
s, new types of thermoplastic elastomers such as TPO and TPV are used more and more in automotive sealing strip
s. According to the type classification, D-shaped sealing strips are divided into large D-shaped, small D-shaped and P-shaped. Sealing strips and E-type sealing strips, but with the development of the automobile industry in recent years, a domestic-made Wonder double-sided adhesive has taken up more and more market shares. It overcomes the shortcomings of 3M adhesive construction that is not resistant to cold and is simple to construct The viscosity is durable, overcoming the influence of the previous temperature on the life of the sealing strip! . 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. Third, the structure of good water absorption is very characteristic. It adopts the structure of independent bubbles. Therefore, the water absorption performance of the product is very good, which will achieve the effect of moisture resistance. This product has many advantages. Not only is the transparent effect good, but the appearance of the product is also very smooth. It is a very soft and elastic product. Moreover, this product has no odor and has good high temperature and low temperature resistance. The use of this product is not prone to aging and deformation. Then, what are the characteristics and uses of rubber sealing strips? 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. According to the classification of materials, automobile sealing strips can be divided into rubber sealing strips; plastic sealing strips; thermoplastic elastomer sealing strips. In use, many problems need to be paid attention to. You can spray a little when installing rubber sealing strips. Soapy water, this method can make it more convenient for you to install, and in the usual maintenance, avoid direct sunlight, and put it in a cool place, so that the rubber seal can exert more performance, and the service life can be Get extended. Fourth, the aviation industry has also been applied in the aviation industry, especially oxygen mask seals and waterproof covers, air-tight seals and shock absorption, etc. The demand for this material is very large in these areas, in order to be able to increase The comfort of the car, we also need to pay attention to some details
