Silicone strip and EPDM strip

by:Kenna     2021-06-21
Silicone strips and EPDM strips, automobile sound insulation and anti-collision strips are divided into 3M adhesive small D-shaped sealing strips, 3M adhesive large D-shaped sealing strips, 3M adhesive large P-shaped sealing strips, A, microwave continuous vulcanization composite Sealing strip: Microwave vulcanization technology is a production technology that was applied and widely promoted after the foreign energy crisis in the 1970s. The use of microwave continuous vulcanization technology can not only produce composite strips made of metal core, solid core rubber and sponge rubber, but also , It is superior to other continuous vulcanization equipment in energy saving and improving work efficiency. 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. 8℃, Disadvantage: Generally, it has a large expansion in mineral oil and lubricating oil, and it is generally a dark-colored product. Application range: Use temperature range -60-150℃, suitable for high temperature and cold coastal areas with strong ultraviolet radiation and middle and high-rise buildings It is recognized by the domestic door and window industry for its wide application range and excellent comprehensive performance. Disadvantages: poor storage stability, hardening during storage, poor cold resistance, relatively high density, and generally black products. According to the material classification, the rubber materials of automobile sealing strips are compact rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shore A95. EPDM can be combined with steel belt, steel wire braided belt, TPE, flannel, flocking, PU coating, organic silicon coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration reduction, wear resistance and decoration effects of the car interior and the outside world and itself, and it can also choose to have good ozone resistance and good aging resistance Performance of neoprene (CR). 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. 2. The construction industry This product has also been applied in the construction industry. Some glass materials can be filled and caulked. The door and window sealing is also inseparable from this product. The above content fully introduces the characteristics of the role of automobile sealing strips. Introduced, we can find that this kind of sealing strip has a very big effect through understanding, and the environmental performance of this product is also very good, which not only brings good comfort, but also safety and beauty. So it is a very practical product. Any product is prone to damage during use. In order to reduce the probability of this phenomenon, it is necessary to carry out effective maintenance on the product. Because of its excellent physical and mechanical properties, it is 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. At the same time, it is very simple in construction, without complicated procedures, and this is also a must-have for an EPDM sealing strip. Many people do not know enough about the product such as EPDM sealing strip, let alone the product. Features and advantages. First of all, the weather resistance of weather resistance products is very good. They can be used in severe cold and hot environments, dry and humid environments for a long time, and they can also have good corrosion resistance. The advantage is that the service life of the product can be prolonged. The main function of silicone strips and EPDM strips for doors and windows is to seal. How to strengthen the sealing performance, then the sealing strips play a very critical role.
