Silicone rubber strip implementation standard

by:Kenna     2021-05-07
Silicone rubber strips implement standard door and window sealing strip types and uses. Introduction: When we install doors and windows in life, there will always be a fixed gap, which causes the door and window departments to close tightly. 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. Because PVC products contain halogens and heavy metals in stabilizers, they are not conducive to environmental protection. Therefore, developed foreign countries and domestic Beijing and coastal cities have eliminated or restricted the use of PVC strips, low temperature elasticity, and the temperature when the tensile capacity reaches 100MPa is -58 , EPDM rubber is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene, international name: EthyienePropyeneDieneMethyiene referred to as EPDM. 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 in recent years from the introduction of foreign technology and domestic independent research and development. 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. 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 in the manufacture of 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. 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 vulcanization bed vulcanization, heating medium For medium 0. Sealing strips play a role in sealing and waterproofing plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips have high requirements for materials. First, they must have strong stretchability and elasticity, and better 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 top is generally used for installation in the push position The sash of the type door and window is used to seal the gap between the frame and the sash. The size of the top can greatly affect the watertight performance of the door and window, and it will also affect the opening and closing of the door and window. If the size of the top is too large, or it is If 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 specification is too small, or the vertical hair is too low, the doors and windows are prone to occur The bracket phenomenon reduces the airtightness of doors and windows. There are generally two types of tops that have been siliconized and those that have not been siliconized. Generally, the use effect after treatment will be better. The quality qualified tops have the following characteristics: 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, which meets the size requirements. The implementation standard of silicone rubber strips is divided into self-adhesive type and card slot type. Different doors and windows are more convenient and feasible in operation and installation, and do not react with any paint or cleaning agent. Customers do not need to worry about the integrity and beauty of doors and windows being damaged. Transmission parts: spring base and keys or fixing screws. Smell your nose for any peculiar smell. Normal PVC sealing strips will have a very pungent smell. Normal silicone rubber sealing strips will only have a little mellow smell, the smell is very small, almost invisible.
are important in ensuring custom sealing strip, and the machine is utilised by everyone from custom sealing strip to custom sealing strip.
