Silicone anti-stab protection strip door and window sealing strip
type and use Introduction: When we install doors and windows in life, there will always be a fixed gap, which causes the door and window departments to close tightly. 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. Some developed countries attach great importance to the sealing of homes, even if the balcony is tight and accurate, they do not forget to have sealing strips. There are many types of door and window sealing strips, some are soft rubber sheets, some are foam plastics, and some are chemical fibers. The materials are different. It can also be used in different locations. Secondly, if the door and window sealing strips contact the door in the hot summer season, the color will be degraded and yellowed due to the sunlight. This is too bad for the beauty. You must go to a regular store to buy . Since silicone rubber sealing strips are mainly produced using silicone rubber materials, they have better sealing performance than other sealing strips. It can also be used in some high-temperature environments. It has excellent weather resistance and can effectively It resists the invasion of natural factors, even if it is used for a long time, there will be no aging damage. Generally, the back of the silicone sealing strip is explained, so it can be effectively combined with other materials without using any adhesive. The materials are bonded together and have good sealing performance. No matter how long it is used in a high temperature environment, it will not fall off, so it has become the first choice for sealing materials. According to the sealing characteristics, automobile sealing strips can be divided into weather sealing strips (WEATHERSTRIP) and general sealing strips (SEALING). Among them, weather sealing strips have hollow sponge foam tubes, which have better temperature and humidity maintenance function and are maintained in normal The process includes the following items. First, the detergent must be cleaned. After the cleaning is not done, a layer of protective agent must be applied. This can prevent aging and prevent dust. 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. Silicone anti-stab protection strip 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 and can be effective. Prevent the loss of temperature. Third, the demand for rubber sealing strips in the automobile industry is very large. Some electronic parts and electrical assembly parts are needed, such as the sealing of windshields and automobile windows, and There are many places such as the outer skin of the high-voltage line, and the spark plug protection cover. 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 can play a delaying effect in the case 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. 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, classification 1, 2 of the sealing strip, according to the surface treatment state, some of the sealing strip surface can be divided into flocking type sealing strip after additional treatment;
