Silicone foam strip design

Silicone foam strip design, secondly, after the sealing strip is damaged, it is easy for rainwater to enter the car. This phenomenon will cause damage to the car body, and it is easy to cause the car body to rust. Through this we can see Although the product such as the seal is a small object, it is also an indispensable part for the car. When the automobile seal is intact, it can effectively reduce the wind noise caused by high-speed driving, and It also improves the air tightness and dust-proof effect of the car. It can be seen that regular maintenance of the sealing strip is very important. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be a fixed gap, which leads to tightly closed doors and windows. 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. 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. Humanization 'In the past, the tradition has always paid more attention to materials and workmanship, ignoring the attention to humanization in use. What are the performance advantages of coated seals? 1. Compression deformation test: 50% compression rate at 70°C continues to compress 22 hours, deformation rate≤10%2, compression force test, under 25% compression rate, apply a force of 15N/100mm, compression rate≤10N3, temperature range test: from -40℃ to 90℃, the sealing performance is not obvious Change 4. Heat conduction K value test: K value ≤ 0 at 0°C. Second, after the sealing strip is damaged, it is easy for rainwater to enter the car, this phenomenon will cause damage to the car body, and it is easy to cause the car body to rust From this point, we can see that although the product of the seal is a small object, it is also an indispensable part for the car. When the car seal is intact, it can be effectively reduced The wind noise caused by high-speed driving also improves the air-tightness and dust-proof effect of the car. It can be seen that regular maintenance of the sealing strip is very important. The wool strip is usually used for the installation of push-position doors and windows. The sash is used 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, and also affect the opening and closing of doors and windows. If the specifications of the tops are too large, or the vertical hairs are too large High, it will be very difficult in assembly, and after assembly, 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, the door and window are prone to bracketing. , Reduce 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, straight surface , The bottom plate and vertical hair are relatively smooth, no bending phenomenon, and there are no pitting and other problems on the bottom plate, which meet the size requirements. Play a key role in the electrical cabinet, and the skeleton seal is the common combination of dense rubber, foam rubber and steel wire. It is extruded into a composition, and used. Cabinet sealing strips are mainly used for cabinets, electrical cabinets, and machinery. They are mainly used for fixing effects and sound insulation, waterproof, dustproof, and sealing. Recommended temperature range: PVC material 20°F-150°f(-29c- 65. A door may not be beautiful, but a sealing strip must be installed to ensure sound insulation, temperature and sealing performance. This shows that the sealing strip is necessary for the door. Nowadays, cars have become very common and have become us The main transportation tool, the basic function can fill some gaps in the body, so that it can achieve a good shock absorption effect and waterproof effect. Features: 1. EPDM has excellent weather resistance and weather resistance means long-term resistance The ability to be cold, hot, dry, and humid, has excellent corrosion resistance to rain and snow, and can completely extend the service life of the rubber strip; 2. Heat aging resistance refers to strong heat-resistant air aging resistance .Automotive 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 20th century Foreign Energy Crisis in the 1970s Later applied and widely promoted production technology, the use of microwave continuous vulcanization technology can not only produce composite strips composed of metal core, solid rubber and sponge rubber, but also compared with other continuous vulcanization methods in terms of energy saving and improving work efficiency. The device is superior.
