How to cut the silicone strip

How to cut the type and purpose of door and window sealing strip with silicone strip Introduction: When we install doors and windows in life, there will always be a fixed gap, which causes the door and window department 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. Silicone sealing strips can also be glued to materials with smooth surfaces 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, often containing 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. Under normal circumstances, EPDM sealing strips can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application areas continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization (the extruded rubber strip is After a certain length is cut, put it in a vulcanizing tank, and put the extruded semi-finished rubber strip into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method, etc.) Several methods). Wooden door, door and window sealing strip product features: self-adhesive wooden door sealing strip is made of EPDM rubber foam, which creates its excellent characteristics, door and window sealing strip characteristics, plastic steel door and window sealing strips have been widely used in recent years, a new generation Doors and windows have better corrosion resistance, weather resistance, noise reduction and heat insulation than ordinary door and window sealing strips. The rubber materials of the sealing strips are more resistant to aging, low temperature, moisture, and chemical corrosion, especially ozone aging. Ethylene propylene diene rubber (EPDM). 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 to cut the silicone strip and 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 on many luxury cars. All use this type of EPDM sealing strip, so 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. 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. The sealing strip is a very important part in doors and windows. It can not only ensure the watertightness of the doors and windows, but also reduce the sound insulation. At the same time, it also has the effect of protection from external forces. However, due to the usual sun exposure, it will cause aging, shrinkage or deformation, so we must regularly Check and look at the specific gravity. If it is of good quality, the weight will be lighter. If it is a defective product, the weight will be heavier. This is because regular manufacturers use calcium carbonate as a filler and some manufacturers use talcum powder to increase the weight of the product. It is easy to distinguish good products from inferior products by looking at the specific gravity when buying.
