The difference between silicone strip
s and rubber strip
s is 15,000 yuan or 6,000 yuan per ton, the cheap one is only 6,000 yuan per ton, the price difference is nearly 10,000 yuan, the quality difference is very big, it is confusing, many sealing strip manufacturers say Its products are in accordance with the GB12002-89 standard, and can issue test reports qualified by authoritative organizations. The sealing strips are classified 1, 2 according to the surface treatment state. Part of the sealing strip surface can be divided into flocking sealing strips after additional treatment; Surface coating sealing strip; with fabric patching sealing strip. Types and purposes 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 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. 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 vulcanizing extruder is generally 16, and the screw length to diameter ratio of the shear head vulcanizing extruder is greater than 20. Nowadays, cars are also very common and have become our main transportation tool. The basic function can fill some gaps in the body, so that good shock absorption and waterproof effects can be achieved. Features: 1, three yuan Ethylene-propylene has excellent weather resistance, weather resistance refers to long-term resistance to severe cold, heat, dryness, and humidity, excellent corrosion resistance to rain and snow, and can completely extend the service life of the rubber strip; 2. Heat aging resistance refers to strong resistance to hot air aging. 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 top can greatly affect the watertight performance of doors and windows, and 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 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. Sealing strip is a product that seals something so that it is not easy to open, and plays the role of shock absorption, waterproofing, sound insulation, heat insulation, dustproof, and fixing. The EPDM rubber strip adopts the microwave vulcanization process One-time molding, smooth and beautiful surface, good elasticity and resistance to compression deformation, weather aging resistance, ozone resistance, chemical resistance, and a wide temperature range (-50℃~+150℃). It has been used in automobile doors and windows. Widely used in manufacturing industries such as curtain walls. A small number of door and window companies in low-level price competition are still in use. Medium and high-end PVC strips can meet the standard indicators and have a relatively long service life. 5. Because of their excellent physical and mechanical properties, they are often used to manufacture airplanes and cars , Trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts, 8℃, EPDM rubber has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical properties
