Primer for silicone strips

by:Kenna     2021-06-20
The special primer for silicone strips, doors and windows bring light and vitality to the room, doors and windows extend the limited space infinitely, say the ternary bc sealing strip (rubber EPDM)-suitable for the special temperature of -40℃-+160℃ Environment, with superior anti-ozone characteristics, purple light reflection characteristics and chemical solvent resistance characteristics, far beyond similar products, widely used in vehicle seals and building seals, in addition to various physical and chemical performance indicators in the field, our company's development and design are different The hardy and heat used in the field and send foam and solid, with special properties that can meet the needs of the application. 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 surface of the silicone rubber sealing strip is very flat. When observing its surface, we will also find that its surface has a very uniform foaming density and good resilience performance. The choice of sealing material determines In order to have long-term softness and elasticity, through formula adjustment, the softness of the sealant after drying can be improved to form a good sealing layer between the sheet metal and the rubber strip. The unique high elasticity of butyl rubber ensures the sealing The glue is easy to peel from the metal sheet without contaminating the sheet metal. Uses are mainly used in the door frame, side windows, front and rear windshield, engine cover and trunk cover, which play the role of waterproof, dustproof, sound insulation, temperature insulation, shock absorption, and decoration. The unique formula design makes three Ethylene propylene rubber sealing strip has excellent anti-aging, high and low temperature resistance and chemical resistance performance, has good elasticity and resistance to compression deformation, and will not crack or deform after long-term use. It is between -50 degrees and 120 degrees. It can maintain its original high sealing performance. 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. 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, the international name: EthyienePropyeneDieneMethyiene is referred to as EPDM. Commonly used weather sealing strips include door frame sealing strips, luggage compartment sealing strips, engine box cover strips, etc. Commonly used general sealing strips include front and rear window sealing strips, corner window sealing strips, inner and outer strips, etc. The unique formula design makes EPDM The rubber sealing strip has excellent anti-aging, high and low temperature resistance and chemical resistance properties, good elasticity and resistance to compression deformation, long-term use will not crack or deform, and it can be between -50 degrees and 120 degrees. Maintain its original high sealing performance. my country's automobile door sealing strip is one of the important parts of the automobile, and it is one of the important parts that determine the quality of the automobile. What are its more important roles in the automobile, foam sealing strip 1, The basic concept of the mechanical seal: the mechanical seal refers to the prevention of fluid by keeping at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal to prevent fluid from sliding. Leaking device. The main function of the special primer for silicone strips is to seal, how to strengthen the sealing, then the sealing strip plays a very important role.
