Wiper Silicone Strip Door and Window Sealing Strip Types and Uses Introduction: When we install doors and windows in our lives, there will always be a certain gap, which leads to tightly closed doors and windows. 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. 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). 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. C, classified by section shape, can be divided into solid core products (round, square , Flat section shape), hollow products and metal-rubber composite products. EPDM rubber sealing strips are much stronger than PVC strips in terms of sealing elasticity and durability. However, due to the need for microwave vulcanization line shaping, processing performance High consumption, usually more than 20 times that of PVC processing, the product cannot be reused, it is not environmentally friendly, and it is not a recommended product. A small number of door and window companies in low-level price competition are still in use. Medium and high-end PVC strips can meet the standard indicators and have a relatively long service life. 5. Because of their excellent physical and mechanical properties, they are often used in the manufacture of airplanes and cars. , Trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts, 8℃, EPDM rubber has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical properties. 2. The semi-finished rubber sealing strip extruded by the vulcanization cold feed extruder is vulcanized by continuous vulcanization process. The vulcanization methods include microwave vulcanization, shear head vulcanization, salt bath vulcanization and fluidized bed vulcanization (also called vulcanization bed vulcanization, heating medium For medium 0. 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, and 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 for installation in the push position The sash of the 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 the doors and windows will increase when they move. If the fire specification is too small, or the vertical hair is too low, the doors and windows are prone to occur The bracket phenomenon reduces the airtightness 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 after treatment will be better. The quality qualified tops have the following characteristics: no obvious defects in appearance, The surface is straight, the bottom plate and vertical bristles 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. Wiping the silicone strip and the weather resistance of the sealing strip is still good at a high temperature of 120 ℃. Maintain elastic properties, shape and function are not affected. Thermoplastic EPDM rubber sealing strips are often used in many luxury cars now. This type of EPDM sealing strips are used in actual use. What kind of performance does it have? First of all, its scalability is relatively large. This is very important. Only when this point is reached, can you maintain good performance when you use it, and at the same time It can be used for a long time without deformation. According to the classification of material types, 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 soapy water when installing the rubber sealing strip. This method can make the installation more convenient, and in the usual maintenance, it is to avoid direct sunlight and place it on In a cool place, the rubber sealing strip can exert more performance and the service life can be extended.rubber seal strip suppliers
custom sealing strip, as the name suggests, find extensive use in custom sealing strip institutions. Since custom sealing strip has become much dependent on technology in today's world, there is wide use of such rubber seal strip suppliers.
