Gear-shaped silicone strip
door and window sealing strip
type and use Introduction: When we install doors and windows in our lives, there will always be a certain gap, which leads to tightly closed doors and windows. 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. According to the classification of materials, automobile sealing strips can be divided into rubber sealing strips; plastic sealing strips; thermoplastic elastomer sealing strips. In use, many problems need to be paid attention to. You can spray a little when installing rubber sealing strips. Soapy water, this method can make it more convenient for you to install, and in the usual maintenance, avoid direct sunlight, and put it in a cool place, so that the rubber seal can exert more performance, and the service life can be Get extended. 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 do not know enough about the product such as EPDM sealing strip, let alone the product. The characteristics and advantages. First of all, the weather resistance of the weather resistance product is very good. It can be used in severe cold and hot environments, dry and humid environments for a long time, and it can also have good corrosion resistance. The advantage is that the service life of the product can be prolonged. Energy-saving doors and windows are roughly composed of profiles, hardware, glass and EPDM door and window sealing strips, as well as several major modules of processing technology. The sealing strips are relatively low cost due to their proportion and are affected by some traditional concepts that do not pay attention to energy-saving standards for doors and windows. , Has been ignored by many door and window manufacturers, but we can’t help but admit that the sealing strip plays a vital role in the door and window system. What important role can EPDM sealing strip play in the door and window system? . 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. The energy-saving doors and windows of the gear-shaped silicone strip are roughly composed of profiles, hardware, glass and EPDM door and window sealing strips, and several major modules of processing technology. The sealing strips have a lower cost due to their proportion, and some do not pay attention to the energy-saving standards of doors and windows. The influence of traditional concepts has been ignored by many door and window manufacturers, but we cannot but admit that the sealing strip plays a vital role in the door and window system. What important role can the EPDM sealing strip play in the door and window system? . 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. Silicone sealing strips can also be glued to materials with a smooth surface because of its high shock resistance and waterproof performance. According to the composite structure of rubber materials, automotive sealing strips can be divided into pure rubber sealing strips-composed of a single type of rubber; 2. Composite sealing strip-composed of dense rubber and foam sponge rubber, and often contains a metal skeleton material in the axial direction inside the dense rubber; three composite sealing strip-composed of two types of dense rubber (one of which is light-colored) and sponge rubber The composition usually contains a metal skeleton and reinforcing fibers inside the compact glue. The main function of doors and windows is to seal, how to strengthen the seal, then the sealing strip plays a very critical role. The common sealing strips on the market are generally made of pvc material. The quality of the sealing strips mainly depends on the pros and cons of the plasticizers added. With the increase in the price of various chemical fields, the price of the sealing strips is constantly increasing. rise.
