How often does the car seal change

How often does the car sealing strip change the type and purpose of the door and window sealing strip 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. At a high temperature of 120℃, the weather resistance of the sealing strip is still good, maintaining elastic properties, and its shape and function are not affected. Thermoplastic EPDM rubber sealing strips are often used in many luxury cars. Type of EPDM sealing strip, what kind of performance does it have in actual use? First of all, it is more flexible, which is very important. Only when this point is reached, can you maintain good performance when you use it, and at the same time, it will not be achieved in long-term use. Deformed. 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 . It plays a key role in various electrical cabinets. The main performance of EPDM products: non-toxic, environmentally friendly, resistant to aging and high temperature, stable performance, and can maintain good performance in summer and winter, taking into account The process performance of commonly used rubber materials sometimes requires the use of combined rubber, such as the combined use of natural rubber (NR) with CR and styrene-butadiene rubber (SBR) or the combined use of polyethylene (PE), EPDM and NR rubber to improve resistance. Ozone. 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. How long does it take to change the car seal can be used at 100-120℃ for a long time, and it can maintain effective physical properties for a long period of time at 140-150℃. It can withstand high temperature of 230-260℃ in a short time, which is sudden to urban construction. In the event of an accident, it can play a delay effect; coupled with the use of special formulas, EPDM rubber feels similar at -50°C to 150°C, which creates a high efficiency work performance for the installation on the production site. 3. Because of EPDM C has excellent ozone resistance and is also known as 'crack-free rubber'. It is especially used in various urban buildings with different atmospheric indexes and completely exposed to the air, and it will show the superiority of its products; 4. Anti-ultraviolet radiation provides environmental protection for residents of high-rise buildings; it can withstand voltages of 60~150KV, corona resistance, electric crack resistance, and arc resistance, which are also very good. 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. High-quality products will improve the overall style and performance of the door in terms of appearance, internal quality, or later use. Wrapped seals are a modern development trend. Where can wrap seals be used? Wooden windows, aluminum-clad wood, aluminum alloy doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, Copper doors, cast aluminum doors, plastic steel doors and windows, etc. The main function of doors and windows is to seal, how to strengthen the seal, then the sealing strip plays a very critical role.
