Silicone weather strip

Types and uses of silicone sealing strips, wind-proof strips, door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be certain gaps, which 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. Among them, the classification according to the title of the device (component) is a common way, which includes the engine room sealing strip, the front and rear wind window sealing strips, the door frame sealing strip, the door sealing strip, the door glass guide groove sealing strip, the lower door dust strip, Internal and external sealing strips for door and window sills, side window sealing strips, sunroof sealing strips, roof cover sealing strips, trunk (luggage box) sealing strips, etc. Installation method: self-contained double-sided tape, just stick it directly (the sticking surface must be smooth, Clean, smooth and dry). Automobile sound insulation and anti-collision strips are divided into 3M back-adhesive small D-shaped sealing strip, 3M back-adhesive large D-shaped sealing strip, 3M back-adhesive large P-shaped sealing strip, A, microwave continuous vulcanization composite sealing strip: microwave vulcanization technology is the 70s of the 20th century The production technology used and widely promoted after the foreign energy crisis in the 1940s, the use of microwave continuous vulcanization technology can not only produce composite strips of metal core, solid core rubber and sponge rubber, but also save energy and improve work efficiency. Other continuous vulcanization methods are superior. According to the sealing characteristics, automobile sealing strips can be divided into weather sealing strips (WEATHERSTRIP) and general sealing strips (SEALING). Among them, weather sealing strips have hollow sponge foam tubes, which have better temperature and humidity maintenance function, and are maintained in normal times. The process includes the following items. First, the detergent must be cleaned. After the cleaning is not done, a layer of protective agent must be applied. This can prevent aging and prevent dust. 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 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. Silicone weatherproof 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 outstanding characteristics. The characteristics of door and window sealing strips Plastic steel door and window sealing strips have been used in recent years A wider new generation of doors and windows, it has 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 ethylene propylene diene monomer rubber (EPDM) which is resistant to ozone aging. With the improvement of people's living standards, the improvement of housing conditions and people's high attention to home decoration, more and more people pay attention to the privacy, sound insulation and sealing effect of indoor rooms, 035W/m2K; 5. Fatigue resistance test: imitation The window has been opened and closed 500,000 times without significant changes in shape. 6. Sound insulation test: only IV68 windows with intermediate rubber strips, reducing noise by 43 decibels7, IV76 windows with intermediate rubber strips and additional rubber strips, reducing noise by 45 decibels8, Outdoor aging resistance test: It has been more than 20 years, and the performance is maintained intact. The series of products are environmentally friendly products and do not contain CFC harmful substances. 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.
As we have known for quite some time, the success of Kenna in the future will depend greatly on our ability to strike a balance between valuable human insight and interaction with technology.
