Food grade silicone strip

Types and uses of food-grade silicone rubber 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 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. 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. , Elastomer TPE water floating sealing strip is applied to door and window sealing strip, mainly divided into: plastic steel door and window sealing strip, aluminum alloy door and window sealing strip, wooden door sealing strip, cold storage door sealing strip, grain storage door sealing strip, flame retardant door and window sealing strip , Glass sealing strips, automatic revolving door sealing strips, building door sealing strips, curtain wall sealing strips, etc., the so-called sealing strips with pores inside, this product is formed at one time through the microwave vulcanization process during production. Therefore, the surface is not only very smooth, but also has good aesthetics. It will not leave any joint marks during production. At the same time, the elasticity and resistance to compression deformation are also very strong. Let us take a detailed look at the hair The characteristics of the bubble sealing strip. Moreover, the design of this EPDM sealing strip is often more advanced. It has an independent bubble structure, so that it can form a good sealing bond rate, and all the bubbles have reached uniformity. The distribution of, it can play a very good performance of expansion and contraction. It is precisely because of this that it can achieve the superior performance of non-flowing, non-deformation, non-cracking and so on in use. It is on the contact material used except for the plane. , Can not be combined with many uneven materials. 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 very high requirements for materials. First, 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 top 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 largely 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 the assembly is completed, the resistance of the doors and windows will increase when they move. If the fire size is too small, or the vertical hair is too low, the door and window are prone to bracket phenomenon, which reduces the airtightness of the door and window. 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 hairs 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. Food-grade silicone strip material: 1. Made of high-quality EPDM rubber, made by foaming technology, 2. The back is made of imported double-sided tape, and the interlayer is grid-shaped glass fiber. Scope of application and installation method: 1. Electrical cabinet sealing strip It is made of ethylene propylene diene monomer (EPDM) rubber with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃). , Contains unique metal clamps and tongue-shaped buckles, sturdy and durable. 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, and 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. 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. The main function of doors and windows is to seal, how to strengthen the seal, then the sealing strip plays a very critical role.
