The role of silicone strip flattening roller

The role of the silicone strip flattening roller Types and uses of door and window sealing strips Introduction: When we install doors and windows in life, there will always be a fixed gap, which causes the door and window 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 product is environmentally friendly, easy to construct, and has good anti-seepage, anti-leakage and water-stop effects. 2) Corrosion resistance, aging resistance, high and low temperature resistance +80℃~-45℃, no flow, no deformation, no embrittlement, long service life, thermoplastic EPDM rubber sealing strip The sealing strip is a new material developed on the basis of imported technology and domestic independent research and development in recent years. It is mainly used for automotive door and window sealing strips. In recent years, it has been used for building door and window sealing. Its outstanding advantages are: ①The performance and service life are equivalent to those of vulcanized EPDM rubber sealing strips. At a high temperature of 120°C, the weather resistance of the sealing strip is still good, and the elasticity is maintained. The shape and function are not affected. The low temperature elasticity, the temperature when the tensile capacity reaches 100MPa is -58, and the characteristics of the neoprene sealing strip: Compared with other special rubbers, the individual performance is worse, but the overall performance balance is good, with excellent weather resistance, ozone resistance, heat aging resistance, oil and solvent resistance, good chemical resistance and excellent flame resistance. , Has good stickiness. 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 decorative 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.). 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. 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. The function of the silicone strip flattening roller can be classified into solid core products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products according to the cross-sectional shape. Among them, the metal rubber composite sealing strip accounts for more than 60% , For the rubber sealing strip, the cross-section design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force, according to the sealing characteristics Classification, can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). 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. B. Sealing strip for continuous vulcanization in salt bath: salt bath vulcanization adopts a salt bath system containing nitrite, which causes great environmental pollution and has been gradually eliminated
There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their custom sealing strip effects. However, recent studies have provided valuable insights into how the intake of may result in improved custom sealing strip.
