Is the silicone strip toxic?

by:Kenna     2021-05-31
Is the silicone strip poisonous? Second, put it together with the silicone rubber sealing strip at high temperature for a period of time (on the roof or in a sunny place), the PVC sealing strip will become very soft in a short time, and the grease on the surface of the sealing strip will precipitate , It is contaminated with dust and yellow (the oil is easy to absorb soil), and the hands are dirty. The physical properties of the silicone rubber sealing strip are unchanged. The pressure cooker sealing ring for household use is made of silicone rubber, which is the use of the resistance of silicone rubber. High temperature and non-toxic environmental protection performance, the physical properties of silicone rubber have no obvious changes in the 200 ℃ working environment. 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. 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. Car sealing strips are also something that can often be used in cars. Use better quality products, so that they can be used for a longer time. Although there are many brands on the market to choose from, it still depends on your actual situation. Choose according to the situation, because different cars are suitable for different sealing strips, so you can choose more to compare above. How to use the sealing strip is worth our attention and needs to be remembered, especially in the hot season. , Try to use it in a cool place to avoid exposure to the sun. 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 microwave vulcanization process is used for one-time molding, with a smooth and beautiful surface, no joint marks, good elasticity and resistance to compression deformation, excellent aging resistance, excellent flame retardant performance, low smoke and low toxicity; stable product performance, high dimensional accuracy, six, Burning, PVC sealing strip will foam, shrink, give off black pungent smoke, and will not burn sufficiently, leaving hard plastic residues. Silicone rubber sealing strips will burn almost smokeless, tasteless, and fully burned. After burning, the material will be white. powder. 8°C,
