Types and uses of door and window sealing strip
s for silicone foam pressure head 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 product is environmentally friendly, easy to construct, and 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 embrittlement, long service life, thermoplastic EPDM rubber sealing strip The sealing strip is a new material developed on the basis of imported technology and domestic independent research and development in recent years. It is mainly used for automotive door and window sealing strips. In recent years, it has been used for building door and window sealing. Its outstanding advantages are: ①The performance and service life are equivalent to those of vulcanized EPDM rubber sealing strips. The characteristics of automobile sealing strips In the -40℃ low temperature resistance test, the sealing strips do not become hard and brittle, and still maintain softness and good adhesion of the strips, showing excellent cold resistance. The automotive sealing strips are mainly composed of Ethylene propylene diene rubber (EPDM) rubber with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃) is formed by foaming and dense compounding of ethylene propylene diene monomer rubber (EPDM). Contains unique metal clamps and tongue buckles, which are durable and easy to install. 8℃, Disadvantage: Generally, it has a large expansion in mineral oil and lubricating oil, and it is generally a dark-colored product. Application range: Use temperature range -60-150℃, suitable for high temperature and cold coastal areas with strong ultraviolet radiation and middle and high-rise buildings It is recognized by the domestic door and window industry for its wide application range and excellent comprehensive performance. Disadvantages: poor storage stability, hardening during storage, poor cold resistance, relatively high density, and generally black products. 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 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 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 strip fob indenter is used in the raw materials for manufacturing sealing strips. The main raw material EPDM used in the past is also constantly updated and developed. It has excellent physical properties and good processing properties. The new type of EPDM can control the molecular length. Chain branching makes the vulcanization performance better, and can increase the extrusion speed and product output. These materials not only have the excellent engineering properties of elastomers, but also have the excellent characteristics of plastics, which are convenient for processing and can be recycled and reused. These materials are gradually replacing EPDM products. Among the raw materials for sealing strips, EPDM, the main raw material used in the past, is also constantly updated and developed. The new EPDM with excellent physical properties and good processing properties can control the long-chain branching in the molecule and make it The vulcanization performance is better, and the extrusion speed and the output of the product can be improved. These materials have the excellent engineering properties of elastomers and the excellent characteristics of plastics, which are convenient for processing and can be recycled and reused. These materials are gradually replacing EPDM. Products.
