Types and uses of silicone foamed flame-retardant silicone seals for doors and windows. Introduction: When we install doors and windows in life, 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. 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 heat resistance and cold resistance, insulation and conductivity, as well as flame retardancy are very good. It can be used at 100-120℃ for a long time, and it can remain effective for a long period of time at 140-150℃. Its physical properties can withstand high temperatures of 230-260℃ in a short period of time, and it can delay the effect of sudden accidents in urban buildings; coupled with the use of special formulas, EPDM rubber feels similar at -50℃ to 150℃ , This has created a high-efficiency work performance for the production site installation. In addition, the material proportion of this type of product (above 1, 4) is comparable to that of PVC (low-end vulcanized EPDM rubber strips have a larger proportion). The window rate is similar to that of PVC rubber strips, and the cost of use is relatively high, which is difficult for door and window companies to accept , The sealing strip can be classified according to several methods such as section shape, vulcanization method, use part and purpose, use material, etc. Product characteristics 1) Light bulk density, strong expansion and contraction strength, non-absorbent (replace the traditional three oil four felt, asphalt wood fir Board and other materials). 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 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. Silicone foamed flame-retardant silicone strip
s are used to maintain the door, window glass, front and rear windows, triangular windows and other parts of the car body. Its better maintenance ensures safe and comfortable driving, but few car owners pay attention to its maintenance. In fact, its maintenance is very important, because once it is aging and damaged, it will cause rain leakage in the car, increase the driving wind noise of the car, and rain leakage can easily make the car body rust. We can keep the car inside the car by maintaining it. Wind and rain, dustproof, heat and sound insulation effects, and when the body is shaken and distorted, it also plays a role in buffering, absorbing shock and maintaining glass. It also plays a decorative role on the edge of the door and window junction, so the owner must always Maintain it. If the smell is great, it is not a regular PVC. The sealing strip is a frequently used product, which is made according to a special process and special materials. The function of the sealing strip is to play a sealing role. It is an indispensable part of many products that can effectively protect the performance of utensils. It can be said that it is indispensable and plays a great role. We cannot ignore it. Another point is that it does not absorb water, so it It is also a material that replaces traditional asphalt. It is not precisely because of its water resistance that it will not be saturated under high water pressure. Another point is that it is more environmentally friendly on the entire material and will not cause any damage to the human body. s damage. 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 spark plug protection covers and many other places
