High temperature varnished cloth silicone strip

by:Kenna     2021-03-07
High-temperature varnished silica gel strips, because PVC products contain halogens and heavy metals in stabilizers, 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, when the tensile capacity reaches 100MPa The temperature is -58. EPDM is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene. The international name: EthyienePropyeneDieneMethyiene is referred to as EPDM. Types and uses 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 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 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. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass touch the glass. 3) It has an independent open-cell bubble structure. The appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion The shrinkage changes and changes to enhance the sealing, expansion, and water stop effect of the joint. 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. It is a kind of sealing strip that uses the characteristics of certain materials to make pores appear inside through processing. It is divided into EPDM foam sealing strip, silicone foam sealing strip, and PU foam sealing strip. Fourth, some prices There are a lot of fillers for cheaper sealing strips, so the surface will not be very shiny, the color will be dim, the cross section of the sealing strip will be very rough, the hand feel is stiff, the stretch is almost inelastic, the color of the silicone rubber seal is bright, the hand feels soft, and the stretch Very elastic, cut off the sealing strip, the broken section becomes a delicate luster. It is also called fireproof silicone sealing strip and fireproof self-extinguishing silicone sealing strip. It is famous for its good flame-retardant and self-extinguishing performance. The main process is to first use high-quality silicone raw materials to make a molded silicone strip through a large extruder. Then it must be made by high room temperature vulcanization and drying. Compared with ordinary silica gel strips, the high temperature resistant flame retardant silica gel strips are different in that it needs to add flame retardant powder to the formula. The silica strips made by doing so are super strong. The flame-retardant and fire-proof performance of the product has played a certain safety guarantee in the sealing of electronic appliances, so many people also call it a fire-proof sealing strip. Wooden door, door and window sealing strip product features: self-adhesive wooden door sealing strip is made of EPDM rubber foam, which creates its excellent characteristics, door and window sealing strip characteristics, plastic steel door and window sealing strips are widely used in recent years, a new generation Doors and windows have better corrosion resistance, weather resistance, noise reduction and heat insulation than ordinary door and window sealing strips. The rubber materials of the sealing strips are more resistant to aging, low temperature, moisture, and chemical corrosion, especially ozone aging. Ethylene propylene diene rubber (EPDM).
