Silicone anti-collision corner protection strip, made of soft and elastic, non-toxic and odorless after special processing, can withstand 200 ℃ high temperature, high pressure and repeated cooking. It is used for heat insulation and insulation of electrical products, and inside drinking water systems. The internal connection of ducts, industrial refrigeration equipment, gas appliances, the sealing of machinery, lamps and other products, and the performance of the sealing strip
s greatly affect the air-tightness, water-tightness, heat loss and other important performance indicators of building doors and windows. And the firmness of doors and windows. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be a fixed gap, which leads 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. 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 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. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass contact the glass. Check regularly for cracks and breaks. If you find that the sealing strip is broken, you can find an adhesive to repair it. The adhesive here is for special use. It is bonded so that it is not difficult to repair the cracks. 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. If your cracks are large or the aging degree is serious, then you don’t need to use the adhesive anymore. It is more convenient to replace with a new one. The replacement method is very simple, but in order to have a good effect, please ask a professional to update it. However, most people choose PVC material, so what should people pay attention to when buying sealing strips? First of all, put the product on your nose and smell it. If it is made of normal PVC material, it will have a little brewing smell, but the smell is very small, almost invisible. For car sealing strips, we must pay more attention to maintenance and master the correct maintenance method, otherwise the maintenance effect will not be achieved. Let us understand the importance of car sealing strip maintenance. The characteristics of the product The elasticity and compression resistance of the strip are very good, and it also has good resistance to aging, ozone and chemical effects, etc., making the product very strong and durable during use, and it is also very convenient to install of. Uses are mainly used in the door frame, side windows, front and rear windshield, engine cover and trunk cover, which play the role of waterproof, dustproof, sound insulation, temperature insulation, shock absorption, and decoration. The unique formula design makes three Ethylene propylene rubber sealing strip has excellent anti-aging, high and low temperature resistance and chemical resistance performance, has good elasticity and resistance to compression deformation, and will not crack or deform after long-term use. It is between -50 degrees and 120 degrees. It can maintain its original high sealing performance. The main function of the silicone anti-collision corner protection door and window is to seal, how to strengthen the sealing, then the sealing strip plays a very key role.
