Types and uses of door and window sealing strip
s of silicone edge banding extruder manufacturers. Introduction: When we install doors and windows in life, there will always be certain gaps, which cause the doors and windows 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. what is? The covering type sealing strip is a composite product made of four kinds of materials with good quality. The tough outer skin not only provides the basic quality guarantee for the covering type sealing strip, but is also beautiful and elegant. It is an excellent companion for modern home doors and windows; thermosetting The core, the main component is PU, which is the main material of the coated sealing strip. Its super plasticity and our company's excellent technology can meet the needs of different door and window manufacturers; the internal PP skeleton and the perfect combination of plastic and rubber TPU The fishbone barb design and the classified application of the double-sided tape imported from Germany further improve the covered sealing strip. 'Specialization' originated from Germany and has been popular in the European market for a long time. It is famous for its environmentally friendly sealing performance. The sound insulation, heat preservation, sealing, impact resistance and environmental protection characteristics of the coated sealing strip have been more and more Many consumers pay attention to 'functionality'. For a long time, German design has always been a well-functioning, rational and reliable image, especially the harmony and unity of the entire product in terms of technology, function, logic and sense of order. The sealing strip structure makes the door leaf and the door sleeve tight and seamless, has stronger sound penetration resistance, and has strong resilience, sound insulation and environmental protection. A few door and window companies in low-level price competition are still using it, middle and high-end PVC strips can reach 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, cars, trains, buses, ships, high and low voltage switch cabinets, glass curtain walls, and aluminum. Sealing parts of alloy heat-breaking windows 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. Semi-finished rubber sealing strip extruded by vulcanized cold feed extruder Continuous vulcanization process is adopted for vulcanization. The vulcanization methods include microwave vulcanization, shear head vulcanization, salt bath vulcanization and fluidized bed vulcanization (also known as fluidized bed vulcanization, the heating medium is medium 0. Sealing strips are used in plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. It plays a role in sealing, waterproofing, etc. The sealing strip has high requirements for the material, first of all, it must have strong stretching ability and elasticity, as well as good temperature resistance and aging resistance. At the same time, in order to ensure the sealing strip and the profile In close contact, 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 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 specifications of the tops are too large, or the vertical hair is too high, it will be very difficult to assemble, and it will be very difficult to assemble. After that, 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 bracketing, which reduces the sealing performance of the doors and windows. The tops are like siliconized There are two types of silicified and non-siliconized treatments. Generally, the treated tops will have better results. The quality qualified tops have the following characteristics: no obvious defects in the appearance, straight surfaces, and the bottom plate and vertical hairs are relatively smooth, without bending, And there are no pits and other problems on the bottom plate, which meets the size regulations. The heat resistance, cold resistance, insulation, conductivity and flame retardancy of the silicone edge banding extruder manufacturer are very good, and can be long-term Used at 100-120℃, it can maintain effective physical properties for a long period of time at 140-150℃, and can withstand high temperature of 230-260℃ in a short time, which can delay the sudden accident of urban construction. Time effect ; Coupled with the use of a special formula, EPDM rubber feels similar at -50°C to 150°C, which creates a high-efficiency work performance for production site installation. 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.
