Types and uses of door and window sealing strip
s for silicone corner joint machines Introduction: When we install doors and windows in our lives, there will always be a fixed gap, which causes the door and window departments 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 surface of the plastic steel door and window sealing strip is smooth and clean, which not only has excellent sealing and waterproof performance, but also plays a beautiful decoration role. In terms of material selection, manufacturers with higher requirements generally choose EPDM rubber or thermoplastic EPDM rubber, according to the location And use classification (1) window glass sealing strip; (2) door sealing strip; (3) decorative strip, molding strip; (4) other sealing strips (trunk lid sealing strip, engine cover sealing strip, water tank sealing strip, Emergency door sealing strip, etc.). Silicone sealing strips can also be glued to materials with a smooth surface because of its high shock resistance and waterproof performance. According to the composite structure of rubber materials, automotive sealing strips can be divided into pure rubber sealing strips-composed of a single type of rubber; 2. Composite sealing strip-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 The composition usually contains a metal skeleton and reinforcing fibers inside the compact glue. The characteristics of sound insulation, heat preservation, sealing, impact resistance and environmental protection have attracted more and more consumers' attention. 'Functionality' has long been a functional, rational and reliable image of German design, especially The whole product is in harmony and unity at the level of technology, function, logic and sense of order. 'The covered sealing strip structure makes the door leaf and the door sleeve tight and seamless, blocking sound penetration, and has strong resilience and sound insulation. Performance and environmental protection. 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. First, they must have strong stretchability and elasticity, as well as relatively 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. It is generally suitable for hanging windows and folding doors and windows. The top is generally used for installation on push The sash of the position type door and window is used to seal the gap between the frame and the sash. The size of the top can greatly affect the watertight performance of the door and window, and it will also affect the opening and closing of the door and window. If the size of the top is too large, or If the vertical hair is too high, it will be very difficult to assemble, and after the assembly is completed, 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, the doors and windows are easy Brackets occur, which reduces the sealing of doors and windows. There are generally two types of tops that have been siliconized and those that have not been siliconized. Generally, the use effect will be better after treatment. The quality qualified tops have the following characteristics: 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 pitting and other problems on the bottom plate, which meets the size regulations. Generally, the EPDM sealing strip can be used stably for more than ten years. With the continuous development and maturity of the thermoplastic elastomer (TPE) technology, the application areas continue to expand. According to the vulcanization classification (1) Discontinuous vulcanization method (the extruded rubber strip
is cut according to a certain length, and then put into a vulcanizing tank to vulcanize. (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method, etc.). The doors and windows are in a quiet room environment. Barriers, doors and windows are also important and interesting bridges for communication between people’s internal world and the external world. The sealing performance of doors and windows is constantly enriched, and the opening is more and more catering to the needs of life. This significant change implies an improvement in the quality of life. In fact, they all represent a trend of living quality. When doors and windows form a concept in the process of human civilization, doors and windows have also become another carrier of human civilization, and they have changed from satisfying the use of functions to conversion to the soul and ideals. The desire for extension. Nowadays, cars have become very common and have become our main means of transportation. The basic function can fill some gaps in the body, so that good shock absorption and waterproof effects can be achieved. Features: 1. EPDM has excellent weather resistance, weather resistance refers to long-term resistance to severe cold, heat, dryness, and humidity, and has excellent corrosion resistance to rain and snow erosion, and can completely extend the rubber strip. Service life; 2. Heat aging resistance refers to strong heat-resistant air aging resistance. The main function of doors and windows is to seal, how to strengthen the seal, then the sealing strip plays a very critical role.
