Is the silicone wiper strip good?

by:Kenna     2021-04-29
Whether the silicone wiper strip is good or not, the sealing performance of the car sealing strip is an important indicator of the quality of the entire car, and the car sealing strip product is one of the important parts that determine the pros and cons of this index. It is widely used The front and rear windshield, doors, windows, engine room, trunk and other body parts of the car fill the gaps between the body parts. It has the functions of shock absorption, waterproof, dustproof, sound insulation, decoration, etc., which is effective for the driver and the entire vehicle. For maintenance purposes, there are many ways to classify automotive sealing strip products, usually according to the title of the device part (component), the type of data, the number of composite data, and the work characteristics. 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. 2. At the same time, put the silicone rubber sealing strip at high temperature for a period of time (placed on the roof or in a sunny place), the PVC sealing strip will become very soft in a short time, the grease on the surface of the sealing strip will be deposited, contaminated with dust, and Yellowing (oil is easy to absorb soil) seepage, dirty hands; the physical properties of silicone rubber sealing strips have no change, the pressure cooker sealing ring for household use is silicone rubber, which uses the high temperature resistance, non-toxic and environmental protection of silicone rubber Performance: There is no obvious change in physical properties of silicone rubber in a working environment of 200°C. Four composite sealing strips-Shanghai Shenya Sealing Parts Co., Ltd. has taken the lead in the domestic development and production of composite sealing strips composed of 4 kinds of rubber materials, and a thin layer of protection is coated on the surface of the foam rubber (bubble tube) Layer glue to further increase the service life of the seals. Car sealing strips are classified according to the surface treatment state. After additional treatment, the surface of some sealing strips can be divided into flocking sealing strips; surface coating sealing strips; automotive sealing strips with fabric stickers Special function classification of sealing strips Some sealing strips have electronic intelligence functions, such as anti-pinch sealing strips. 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. 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. There is no obvious change in the physical properties of silicone rubber at -50°C. Fifth, depending on the specific gravity, how many meters can be produced per kilogram, the PVC sealing strip with heavy calcium added, you can stretch it back and forth several times by hand, and a small amount of white powder will appear on the surface. The density of PVC sealing strips should be 1,4-1,6. Silicone rubber sealing strips should be filled with nano-scale silica as a filling and reinforcing effect. The texture is light and the density ratio is between 1,1-1,25. The material rate is 20% higher than that of PVC sealing strips. Automobile sealing strips can be classified into solid core products (round, square, flat cross-sectional shapes), hollow products, and metal rubber composite products according to the cross-sectional shape.
