Feiying silicone glass scraper door and window sealing strip
types and uses Introduction: In our life, when we install doors and windows, there will always be a fixed gap, which causes the door and window departments 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. It is suitable for all kinds of doors, windows, etc. 2. Cabinet sealing strips have developed their own characteristics based on the use of electric cabinets and based on 20 years of experience in the development of sealing strips, which have good sealing performance. , Waterproof, fire-proof, insect-proof, windproof, light-proof, anti-collision and long service life, etc. 1. Three-composite steel frame, not easy to deform and shrink, firm assembly, and good sealing 2. Sealing strips for doors, windows and curtain walls, products It has good elasticity, resistance to migration, and can effectively block noise, dust, and weather. These advantages are irreplaceable by other materials such as PVC. It can meet the needs of design and use for products with different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, and special performance requirements. Automobile sealing strip production process 1. Extrusion of rubber sealing strips for automobiles is extruded by a cold feed extruder. The extrusion head has a single head, a composite (double composite and multiple composite) head and a shear head. , The screw length-to-diameter ratio of the microwave vulcanization extruder is generally 16, and the screw length-to-diameter ratio of the shear head vulcanization extruder is greater than 20. 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 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. The sound insulation, heat preservation, airtightness, impact resistance and environmental protection characteristics of Feiying silicone glass scrapers have attracted more and more consumers’ attention. 'Functionality' has long been a feature of German design. A rational and reliable image, especially the harmony and unity of the entire product in terms of technology, function, logic and sense of order. 'The covered sealing strip structure makes the door leaf and the door sleeve tight and seamless, blocking sound penetration stronger, and has a better Strong resilience, sound insulation and environmental protection. Silicone sealing strips can also be glued to materials with smooth surfaces because of its high shock resistance and waterproof performance. Automotive sealing strips can be classified into pure rubber according to the compound structure of the rubber compound. Sealing strip-composed of a single type of rubber; two composite sealing strips-composed of dense rubber and foam sponge rubber, often containing a metal skeleton material in the axial direction inside the dense rubber; three composite sealing strips-composed of two dense rubbers (One of them is light-colored) and sponge rubber, usually containing metal skeleton and reinforcing fiber inside the dense rubber. 8℃, the disadvantage: it generally has a large expansion in mineral oil and lubricating oil, and is generally a dark product. Scope of application: Operating temperature range -60-150℃, suitable for high temperature and cold coastal areas with strong ultraviolet radiation and middle and high-rise buildings. With wide application range and excellent comprehensive performance, it is recognized by the domestic door and window industry. Disadvantages: poor storage stability, during storage Hardening will occur, the cold resistance is not good, the relative density is relatively high, generally black products.
