How much is the silicone rubber strip
one meter door and window sealing strip type and use Introduction: When we install doors and windows in life, there will always be a certain 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 lip length and thickness should be appropriate. Too thick or too long will increase the resistance of the glass to lift. Too thin or too short will cause the glass to not be well guided and sealed, resulting in vibration, noise, and rain leakage; the second is The shape and size of the bottom of the section are designed. There are protrusions on the section of the window steel channel, which is used to assemble the guide groove. Therefore, the bottom of the guide groove section should be designed with a corresponding structure, which is easy to install and can take advantage of the elasticity of the sealing strip itself. It is attached to the steel guide groove to prevent it from coming out; it is the shape and size of the outer edge. In order to improve the appearance, the outer surface of the guide groove should be closely attached to the body. At a high temperature of 120°C, the weather resistance of the sealing strip is still good, maintaining elastic properties, and its shape and function are not affected. It is elastic at low temperature and the temperature when the tensile capacity reaches 100MPa is -58. The characteristics of the neoprene sealing strip: Compared with other special rubbers, the individual performance is worse, but the overall performance balance is good, with excellent weather resistance, ozone resistance, heat aging resistance, oil and solvent resistance, good chemical resistance and excellent flame resistance. , Has good stickiness. The surface of the silicone rubber sealing strip is very flat. When observing its surface, we will find that its surface has a very uniform foaming density and also has good resilience performance. The choice of sealing material determines In order to have long-term flexibility and elasticity, through formula adjustment, the softness of the sealant after drying is improved, so that a good sealing layer is formed between the sheet metal and the rubber strip. The unique high elasticity of butyl rubber ensures the sealing The glue is easy to peel from the metal sheet without contaminating the sheet metal. 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 rubber strips are commonly used in weather sealing strips such as door frame sealing strips, trunk sealing strips, engine box cover strips, etc. Commonly used general sealing strips include front and rear wind window sealing strips and corner window sealing strips, inner and outer strips, etc., unique The formula design makes the EPDM rubber seals have excellent anti-aging, high and low temperature resistance and chemical resistance performance, good elasticity and compression deformation resistance, long-term use will not crack or deform, at -50 degrees It can maintain its original high sealing performance between 120 degrees. Material: 1. Made of high-quality EPDM rubber, made by foaming process, 2. The back is made of imported double-sided tape, and the interlayer is meshed glass fiber.
