Silicone strip high airtightness

by:Kenna     2021-05-16
Silicone strips are highly airtight. Because PVC products contain halogens and heavy metals in stabilizers, they are not conducive to environmental protection. Therefore, developed foreign countries and domestic Beijing and coastal cities have eliminated or restricted the use of PVC strips. Low temperature elasticity and tensile capacity of 100MPa When the temperature is -58, EPDM is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene. The international name: EthyienePropyeneDieneMethyiene is referred to as EPDM. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be certain gaps, which will cause the doors and windows to close tightly. The role of door and window sealing strips is 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 high requirements for materials. First of all, 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 weight of the lightweight foam sealing strip is very light, which brings great convenience to the transportation and use process, and the product's strength and toughness are also very good. It can be used in any environment and can be used at very high temperatures. Working for a long time in a high and low temperature environment, these advantages have expanded the application range of the product. Then, what are the main application areas? 1. Modern industry and defense industry are not only very common in life, but also can be used in modern industry and defense industry to help companies produce products. The expensive one is fifteen to six thousand yuan per ton, and the cheap one is only 6,000 yuan per ton. The price difference is nearly 10,000 yuan, and the quality difference is very big, which is confusing. Many sealing strip manufacturers claim that their products are in accordance with GB12002-89 , And can issue a test report qualified by an authoritative organization, the classification of sealing strips 1, 2, according to the surface treatment status, some of the sealing strip surface can be divided into flocking type sealing strips after additional treatment; surface coating sealing strips; with fabric Adhesive sealing strip. 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. Third, the structure of good water absorption is very characteristic. It adopts the structure of independent bubbles. Therefore, the water absorption performance of the product is very good, which will achieve the effect of moisture resistance. This product has many advantages. Not only is the transparent effect good, but the appearance of the product is also very smooth. It is a very soft and elastic product. Moreover, this product has no odor and has good high temperature and low temperature resistance. The use of this product is not prone to aging and deformation. Then, what are the characteristics and uses of rubber sealing strips? 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 the sealing strip is like this. Although the product is a small object, it is also an indispensable part for the car. When the car sealing strip is intact, it can effectively reduce the wind noise caused by high-speed driving, and it also improves the car’s air. Tightness and dust-proof effect, it can be seen that regular maintenance of the sealing strip is very important. According to the material classification, the rubber materials of automobile sealing strips are dense rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shao 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. It can also choose to have good ozone resistance and good aging resistance. Performance of neoprene (CR).
