Window silicone rubber strip

by:Kenna     2021-04-23
Window silicone rubber strips, EPDM sealing strips can generally be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application fields continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization After the extruded rubber strip is cut to a certain length, it is put into a vulcanizing tank to vulcanize, and the semi-finished product of the extruded rubber strip is put into the model to vulcanize); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, heat Several methods such as air continuous vulcanization). Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be a fixed 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 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. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass touch the glass, 3) It has an independent open-cell bubble structure, and the appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion. The shrinkage changes and changes to enhance the sealing, expansion, and water-stop effect of the joint. In doors and windows, it is one of the inconspicuous small accessories, but it directly affects people's living environment. Based on years of professional experience in door and window sealing products and understanding of the market and customer needs, the world's advanced sealing products have been independently developed by introducing foreign advanced technology. To meet the high-end customers at home and abroad: the pursuit of sealing will never stop, and we are also maintaining the original advantages, let you 'it must be'! The mute contains special sound-absorbing cotton, which can effectively absorb the noise of the movable window leaking into the room. It has better sound insulation performance than ordinary sealing rubber strips, and can improve the sound insulation performance of doors and windows by 35%. 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. B. Sealing strip for continuous vulcanization in salt bath: Salt bath vulcanization adopts a salt bath system containing nitrite, which pollutes the environment and has been gradually eliminated. C. According to the section shape, it can be divided into solid core products (round, square , Flat cross-section shape), hollow products and metal rubber composite products, EPDM rubber sealing strips are much stronger than PVC strips in terms of sealing elasticity and durability, but due to the need for microwave vulcanization line shaping, processing performance High consumption, usually more than 20 times that of PVC processing, the product cannot be reused, it is not environmentally friendly, and it is not an advocated product. 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).
