The difference between silicone strips and EPDM strips

by:Kenna     2021-06-21
The difference between silicone strips and EPDM strips is still used by a small number of door and window companies in low-level price competition. Middle and high-end PVC strips can reach standard indicators and have a relatively long service life. 5. Due to excellent physical properties Mechanical properties, so it is often used to manufacture airplanes, cars, trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy thermal windows, sealing parts and diving products, high pressure steam hoses, tunnels, viaduct joints, etc. 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 The electrical insulation and elasticity as well as other physical and mechanical properties. 2. The semi-finished rubber sealing strip extruded by the vulcanization cold feed extruder is vulcanized by continuous vulcanization process. The vulcanization methods include microwave vulcanization, shear head vulcanization, salt bath vulcanization and Fluidized bed vulcanization (also known as fluidized bed vulcanization, heating medium is 0. Types and uses of door and window sealing strips. 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 information about the types of door and window sealing strips for you. Door and window sealing strips are in The use can be divided into major categories: glass sealing strip, door leaf door cover sealing strip and wool strip. 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. , The top is mainly used to seal the gap between the frame and the fan. It is said that in the installation process of various doors and windows, the sealing strip is indispensable. The sealing strip plays a role in the plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing, waterproofing, etc. The sealing strip has high requirements on the material, first of all it must have strong stretching ability 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, and it is generally suitable for hanging windows and folding doors and windows. These advantages are irreplaceable by other materials such as PVC. It is suitable for different shapes, different materials, or cold, heat-resistant, and hair-resistant Foam, solid body, and products with special performance requirements can all meet the needs of design and use. Automobile sealing strip production process 1. Extrusion of rubber sealing strips for automobiles is extruded by a cold feed extruder. The die has a single die, a composite (double composite and multiple composite) die and a shearing die. Among them, the screw length to diameter ratio of the microwave vulcanization extruder is generally 16, and the screw length of the shearing die vulcanizing extruder Ratio is greater than 20. Durable maintains stable performance and long service life in different environments, anti-aging, wear-resistant, non-wrinkle, non-stretching, non-stick paint surface, not affected by high temperature and dust, Non-mildew and anti-ultraviolet and ozone erosion. Our value to you starts from your experience. It is durable and new forever. It is the real experience of users. The beautifully wrapped PU sealing strip is green and environmentally friendly, and it is stylishly sealed; it is a perfect solution for sealing Contradiction with sound insulation , To achieve the dual effects of sealing and sound insulation; doors and windows perfectly match the product. 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 expensive one is fifteen to six thousand yuan per ton, and the cheap one is only 6,000 yuan per ton. The price difference is nearly 10,000 yuan, and the quality difference is very big, which is confusing. Many sealing strip manufacturers claim that their products are in accordance with GB12002-89 , And can issue a test report qualified by an authoritative organization, the classification of sealing strips 1, 2, according to the surface treatment status, some of the sealing strip surface can be divided into flocking type sealing strips after additional treatment; surface coating sealing strips; with fabric Adhesive sealing strip.
