What kind of silicone foam strip manufacturer
s use to the types and uses of door and window sealing strips Introduction: When we install doors and windows in life, there will always be certain gaps, resulting in 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. The surface of the plastic steel door and window sealing strip is smooth and clean. It not only has excellent sealing and waterproof performance, but also plays a role of beautiful decoration. In terms of material selection, manufacturers with higher requirements generally choose EPDM rubber or thermoplastic EPDM rubber, according to the location And use classification (1) window glass sealing strip; (2) door sealing strip; (3) decorative strip, molding strip; (4) other sealing strips (trunk lid sealing strip, engine hood sealing strip, water tank sealing strip, Emergency door sealing strip, etc.). There is no obvious change in the physical properties of silicone rubber at -50°C. Fifth, depending on the specific gravity, how many meters can be produced per kilogram, the PVC sealing strip with heavy calcium added, you can stretch it back and forth several times by hand, and a small amount of white powder will appear on the surface. The density of PVC sealing strips should be 1,4-1,6. Silicone rubber sealing strips should be filled with nano-scale silica as a filling and reinforcing effect. The texture is light and the density ratio is between 1,1-1,25. The material rate is 20% more than that of PVC sealing strip. It 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. It can be used in sudden accidents to urban buildings To delay effect; coupled with the use of special formula, EPDM rubber feels similar at -50℃ to 150℃, which creates high efficiency work performance for installation on the production site. 3. Because EPDM has excellent resistance Ozone, also known as 'crack-free rubberIt provides environmental protection for residents of high-rise buildings; it can withstand voltages of 60~150KV, corona resistance, electric crack resistance, and arc resistance, and it is also very good. 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 been silicified and those that have not been silicified. Generally, the effect of treatment 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. Silicone foam strip
s can be divided into self-adhesive type and card slot type. They are used in different doors and windows. It is convenient and feasible in operation and installation. It does not react with any paint or cleaning agent. Customers do not need to worry about doors and windows. Integrity and aesthetics have been damaged. Transmission parts: spring skip seat and key or fixing screw 1. Use your nose to smell whether there is any peculiar smell. Normal PVC sealing strips will have a pungent odor, normal silicone rubber sealing strips There will only be a little mellow taste, and the taste is very small, almost inaudible. New types of thermoplastic elastomers such as TPO and TPV are used more and more in automotive sealing strips. According to the type classification, D-type sealing strips are divided into large D-type, small D-type sealing strip, P-type sealing strip and E-type. Sealing strip, but with the development of the automobile industry in recent years, a domestic-made Wonder double-sided adhesive has taken up more and more market shares. It overcomes the shortcomings of 3M adhesive construction that is not cold-resistant, simple construction, durable and viscous. The effect of the previous temperature on the life of the sealing strip!
