Is silicone strip sealing harmless to people? 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, leading 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. Durability Maintains stable performance and long service life in different environments, anti-aging, abrasion resistance, no wrinkle, no stretching, no sticking to the surface of the paint, not affected by high temperature, dust, mildew resistance Ultraviolet and ozone erosion, our value to you starts from your experience. It is durable and lasting. It is the real experience of users. The beautiful coated PU sealing strip is green and environmentally friendly and stylishly sealed; it perfectly solves the contradiction between sealing and sound insulation , To achieve the dual effects of sealing and sound insulation; doors and windows perfectly match the product. Under normal circumstances, EPDM sealing strips can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application areas continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization (the extruded rubber strip is After a certain length is cut, put it in a vulcanizing tank, and put the extruded semi-finished rubber strip into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method, etc.) Several methods). Second, high heat insulation. In the process of use, it has good heat insulation, which greatly reduces the thermal conductivity. Therefore, the heat insulation of this product is very good, which can effectively prevent the loss of temperature. , Third, the automobile industry The demand for rubber sealing strips in the automobile industry is very large. Some electronic parts and electrical assembly parts are required to be used, such as the sealing of windshields and automobile windows, as well as the outer skin of high-voltage lines. There are many places such as spark plug protection covers. 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. 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. Is the silicone rubber seal harmless to people? 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 are concerned about the EPDM sealing strip. The product is not well understood, let alone the characteristics and advantages of the product. First of all, the weather resistance of the weather resistance product is very good. It can be used in severe cold and hot environments as well as dry and humid environments for a long time, and it can also have very good weather resistance. Good corrosion resistance, these advantages can extend the service life of the product. All of the above characteristics are also the advantages of foam sealing strips. Through understanding, we can find that the reason why this product is popular in the market is because the product has many characteristics and advantages. The temperature in winter is very low. If a product such as a car seal is damaged, it is easy for air-conditioning to enter the car, and wind noise is also prone to appear. This sound feels like the door is not closed tightly, which will affect the comfort of the ride. . 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. The main function of doors and windows is to seal, how to strengthen the seal, then the sealing strip plays a very critical role.
