Silicone rubber compound slitting

by:Kenna     2021-05-13
The 'specialization' of silicone rubber compound strips 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 More and more consumers pay attention to environmental protection characteristics. 'Functionality' has long been a functional, rational and reliable image of German design, especially the entire product in terms of technology, function, logic and sense of order. Harmony and unity,' the covered 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. Types and uses of door and window sealing strips: In our daily life, when we install doors and windows, there will always be certain gaps, which cause the doors and windows to close tightly. The role of door and window sealing strips is used to eliminate these gaps. But there are many types of door and window sealing strips, and their uses It’s also different. I’m here to sort out some information about the types of door and window sealing strips for everyone. The use of door and window sealing strips can be divided into broad categories: glass sealing strips, door leaf and door cover sealing strips and wool strips. Among them, glass sealing strips are 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 leaf. In the installation process of various doors and windows Among them, 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. The sealing strip has high requirements for materials, and must have a strong tensile ability first And elasticity, as well as 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. These advantages The performance is irreplaceable by other materials such as PVC. It can meet the needs of design and use for different shapes, different materials, or products with cold resistance, heat resistance, foaming, solid body, and special performance requirements. Strip production process 1. Extrusion of rubber sealing strips for automobiles is extruded by a cold feed extruder. The extruder head has a single head, a composite (double composite and multiple composite) head and a shear head. Among them, microwave The screw length-to-diameter ratio of the vulcanizing extruder is generally 16, and the screw length-to-diameter ratio of the shearing head vulcanizing extruder is greater than 20. The characteristics of sound insulation, heat preservation, sealing, impact resistance and environmental protection are becoming more and more important. 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, and has stronger sound penetration resistance, and has strong resilience, sound insulation and environmental protection. 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 sealing strip is to improve the airtightness and prevent wind and rain from entering the car. In order to avoid the occurrence of the above, the sealing strip must be maintained regularly. 5. Because of its excellent physical and mechanical properties, it is often used in manufacturing Airplanes, cars, trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-insulating window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts. New types of thermoplastic elastomers, such as TPO and TPV, are used more and more in automotive sealing strips. According to the type classification, D-type sealing strips are divided into large D-type, small D-type sealing strip, P-type sealing strip and E-type. Sealing strip, but with the development of the automobile industry in recent years, a domestic-made Wonder double-sided adhesive has taken up more and more market shares. It overcomes the shortcomings of 3M adhesive construction that is not resistant to cold, simple construction, and durable adhesiveness. The effect of the previous temperature on the life of the sealing strip! . 3. Among them, the weather sealing strip has a hollow sponge tube, which has a good temperature and humidity maintenance function. The commonly used weather sealing strips include door frame sealing strips, trunk sealing strips, engine box cover strips, etc., and common general sealing strips have front and back Windshield sealing strips and corner window sealing strips, inner and outer strips, etc., 4, 5, according to material types, can be divided into rubber sealing strips; plastic sealing strips; thermoplastic elastomer sealing strips, special function classification, some sealing strips have electronic Intelligent functions, such as anti-pinch seals, etc.
