Butt joint method of silicone sealing tape

by:Kenna     2021-07-01
The method of connecting silicone sealant strips, the 'professional' coated seal strip originated from Germany, and has been popular in the European market for a long time. It is well-known for its environmentally friendly sealing performance. PVC seal strip vendors have made great efforts in the use of fillers, and some In order to pursue a larger output, the manufacturer uses talc, heavy calcium and the like as fillers, which greatly increases the proportion of the sealing strip products. (Our users generally buy by kilograms and use them by length. ) This invisibly increases the cost and seriously reduces the quality. Don’t try. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be certain gaps, which will cause the doors and windows to close tightly. 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 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. Of course, rubber sealing strips can also be used in medical applications. No matter what kind of application the product is used in, the use effect is very good. It can meet everyone's needs and bring you a lot of help. The use effect of the sealing strip is very ideal, and the color and specifications can be customized according to the needs of customers. The packaging requirements are also installed according to the needs of the customers, so choosing this product can bring you a lot Convenience. 6) Classification and function, high-quality sealing strips will improve the overall style and performance of the door in terms of appearance, internal quality, or later use, and covered sealing strips are the modern development trend, and the humanized 'past' Traditional sealing strips have always paid more attention to materials and workmanship, ignoring the attention to humanization in use. With the improvement of people’s living standards, the improvement of housing conditions and people’s high attention to home decoration, the privacy of indoor rooms, More and more people pay attention to the sound insulation and sealing effect. The top is 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 top can greatly affect the watertightness of the door and window. Performance, and will also affect 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 assembly, the resistance of the doors and windows will increase when they move. . If the fire specification is too small, or the vertical hair is too low, the door and window are prone to bracket phenomenon, which reduces the sealing performance of the door and window. There are two types of wool strips that have been silicified and those that have not been silicified. Generally, they have been treated. The use effect will be better. The quality qualified top has the following characteristics: no obvious defects in appearance, straight surface, smooth bottom plate and vertical hair, no bending phenomenon, and no pitting and other problems on the bottom plate, conforming to the size Regulations. The product is environmentally friendly, easy to construct, has good anti-seepage, anti-leakage and water-stop effects, 2) corrosion resistance, aging resistance, high and low temperature resistance +80℃~-45℃, no flow, no deformation, no brittleness, long service life , Thermoplastic EPDM rubber sealing strip This sealing strip is a new material developed in recent years from the introduction of foreign technology and domestic independent research and development. It is mainly used for automobile door and window sealing strips. In recent years, it has been used in construction Door and window sealing strips, its outstanding advantages are: ①The performance and service life are equivalent to those of vulcanized EPDM rubber sealing strips. It also has good dustproof, sound insulation and decorative functions, and it also protects the car body and is effective It improves the comfort of the ride. The characteristics of the automobile sealing strips are not hardened or brittle in the -40℃ low temperature resistance test. The sealing strips do not become hard and brittle. They still maintain softness and good adhesion of the strips, showing excellent Cold resistance, EPDM sealing strip performance characteristics: excellent comprehensive performance, outstanding ozone resistance, excellent weather resistance, good high temperature and low temperature resistance, outstanding chemical resistance, resistance to a variety of polar solutes, relatively Density is small. Second, at the same time, put the silicone rubber sealing strip at high temperature for a period of time (on the roof or in a sunny place), the PVC sealing strip will become very soft in a short time, and the grease on the surface of the sealing strip will be separated and contaminated Dust, and yellowing (the oil is easy to absorb soil), seepage, dirty hands; the physical properties of silicone rubber seals have no change, the pressure cooker seals for household use are made of silicone rubber, which is the use of the high temperature resistance of silicone rubber. Non-toxic and environmentally friendly performance, silicone rubber under 200℃ working environment
