Types and uses of silicone burr door and window sealing strip
s Introduction: When we install doors and windows in life, there will always be certain gaps, which 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. According to the material classification, the rubber materials of automobile sealing strips are dense rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shao A95. EPDM can be combined with steel belt, steel wire braided belt, TPE, flannel, flocking, PU coating, organic silicon coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration reduction, wear resistance and decoration effects of the car interior and the outside world and itself. It can also choose to have good ozone resistance and good aging resistance. Performance of neoprene (CR).

Performance of neoprene (CR). 6) Classification and function, high-quality sealing strips will improve the overall style and performance of the door in terms of appearance, internal quality, or later use, and covered sealing strips are the modern development trend, and the humanized 'past' Traditional sealing strips have always paid more attention to materials and workmanship, ignoring the attention to humanization in use. With the improvement of people’s living standards, the improvement of housing conditions and people’s high attention to home decoration, the privacy of indoor rooms, More and more people pay attention to the effect of sound insulation and sealing. Sealing strips play a role in sealing and waterproofing plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips have high requirements for materials and must first have a strong pull Extensibility and elasticity, as well as better 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. The top is generally used to install on the sash of the push-position door and window to seal the gap between the frame and the sash. The specifications of the top can greatly affect the watertight performance of the door and window, and also affect the opening and closing of the door and window. If the size of the fire is too large, or the vertical hair is too high, it will be very difficult to assemble, and after the assembly is completed, the resistance of the door and window will increase when the door and window move. If the fire specification is too small, or the vertical hair If it is too low, the door and window are prone to bracket phenomenon, which reduces the sealing performance of the door and window. Generally there are two types of tops that have been siliconized and those that have not been siliconized. Generally, the use effect after treatment will be better. The quality of qualified tops are The following features: no obvious defects in appearance, straight surface, smooth bottom plate and vertical hair, no bending phenomenon, no pitting and other problems on the bottom plate, in line with the size requirements. Silicone strips have high-quality burrs from the appearance and Either the internal quality or the later use will improve the overall style and performance of the door, and the covered sealing strip is the modern development trend. Where can the covered sealing strip be used? Wooden windows, aluminum-clad wood, aluminum alloy Doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, copper doors, cast aluminum doors, plastic steel doors and windows B. Salt bath continuous vulcanization sealing strip: Salt bath vulcanization adopts a nitrite-containing salt bath system, which has great environmental pollution and has been gradually eliminated. C, according to the cross-sectional shape classification can be divided into solid core products (round , Square, flat cross-section shapes), hollow products and metal rubber composite products, EPDM rubber sealing strips are much stronger than PVC strips in terms of sealing elasticity and durability, but due to the need for microwave vulcanization line shaping, The processing energy consumption is high, usually more than 20 times that of PVC processing. The product cannot be reused, is not environmentally friendly, and is not an advocated product.
