It is anti-aging, resistant to abrasion, surface is not wrinkled, stretched, non-stick paint surface, and is not affected by high temperature and dust. , Non-mildew and anti-ultraviolet and ozone erosion. Our value to you starts from your experience. It is durable and new forever, which is the real experience of users. The beautiful coated PU sealing strip
is green and environmentally friendly, and it is stylishly sealed; a perfect solution The contradiction between sealing and sound insulation realizes the dual effect of sealing and sound insulation; doors and windows are perfectly matched with products. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be a fixed gap, which leads to tightly closed doors and windows. The door and window sealing strips are 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 very high requirements for materials. First, 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. According to the cross-sectional shape classification, automobile sealing strips can be divided into solid core products (round, square, flat cross-sectional shapes), hollow products and metal-rubber composite products. Second, heat aging resistance EPDM sealing strips are in production Many experiments have been carried out before. It can be seen from the experiment that the product can continue to work in a high-temperature environment without aging. Therefore, many companies use the product to improve work efficiency to obtain More profit. Under normal circumstances, EPDM sealing strips can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application areas continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization (the extruded rubber strip is After a certain length is cut, put it in a vulcanizing tank, and put the extruded semi-finished rubber strip into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method, etc.) Several methods). The top 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 largely 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 the assembly is completed, the resistance of the doors and windows will increase when they move. If the fire size is too small, or the vertical hair is too low, the door and window are prone to bracket phenomenon, which reduces the airtightness of the door and window. 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 hairs 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. The auxiliary seal of the compensation ring is a metal bellows called a bellows mechanical seal. 2. The composition of the mechanical seal: There are mainly the following four types of components, a, the main seal: moving ring and static ring, b, the auxiliary seal: seal Ring, c, compression parts: spring, push ring, d, three. At the same time, put the PVC sealing strip and the silicone rubber sealing strip in the freezer compartment of the refrigerator. After a few hours, the PVC sealing strip will feel very stiff and easy to break. , There is no change in the physical properties of silicone rubber sealing strips. 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. The main function of the silicone strip
vulcanization method is to seal, how to strengthen the sealing, then the sealing strip plays a very key role. The common sealing strips on the market are generally made of pvc material. The quality of the sealing strips mainly depends on the pros and cons of the plasticizers added. With the increase in the price of various chemical fields, the price of the sealing strips is constantly increasing. rise.
