How to install the silicone strip in the pressure cooker Type and purpose of the door and window sealing strip
Introduction: When we install doors and windows in life, there will always be a fixed gap, which causes the door and window departments to close tightly. 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. Automobile sound insulation and anti-collision strips are divided into 3M back-adhesive small D-shaped sealing strip, 3M back-adhesive large D-shaped sealing strip, 3M back-adhesive large P-shaped sealing strip, A, microwave continuous vulcanization composite sealing strip: microwave vulcanization technology is the 70s of the 20th century The production technology used and widely promoted after the foreign energy crisis in the 1940s, the use of microwave continuous vulcanization technology can not only produce composite strips of metal core, solid core rubber and sponge rubber, but also save energy and improve work efficiency. Other continuous vulcanization methods are superior. Sealing strip is a product that seals something so that it is not easy to open, and plays the role of shock absorption, waterproofing, sound insulation, heat insulation, dustproof, and fixing. EPDM rubber strip adopts microwave vulcanization process One-time molding, smooth and beautiful surface, good elasticity and resistance to compression deformation, weather aging resistance, ozone resistance, chemical resistance, and a wide temperature range (-50℃~+150℃). It has been used in automobile doors and windows. Widely used in manufacturing industries such as curtain walls. According to the cross-sectional shape, it can be divided into solid core products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products. Among them, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips 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, they can be divided into weather seals. Strip (WEATHERSTRIP) and general sealing strip (SEALING). 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. 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. How to install the silicone strip in the pressure cooker. The silicone sealing strip can also be glued to the smooth surface of the material, because its shock resistance and waterproof performance are very high. According to the compound structure of the rubber compound, the car sealing strip can be divided into pure rubber sealing strips-by A single type of rubber composition; two composite sealing strips-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 strips-composed of two dense rubbers (one of which is Light color) and sponge glue, usually containing a metal skeleton and reinforcing fibers inside the dense glue. Talking about the important role of epdm for doors and windows. With the further development of science and technology and the continuous improvement of living standards, and the call of an energy-saving harmonious society that has been advocated, we all know that doors and windows are the eyes of the building, and its energy loss can be It accounts for 40% of the total energy loss of buildings, which has attracted enough attention, especially in large cities like the capital Beijing. In 2004, the heat transfer coefficient of doors and windows (indices for heat preservation and energy saving) was used as a mandatory acceptance index. Provinces, cities and regions across the country have also attracted great attention and implementation, and energy-saving doors and windows have become the mainstream of building doors and windows. 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.
