Silicone sponge strip density

Silicone sponge strip density door and window sealing strip types and uses Introduction: When we install doors and windows in our lives, there will always be a fixed gap, which leads to tightly closed doors and windows. 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 'specialized' covered sealing strip originated from Germany and has been popular in the European market for a long time. It is famous for its environmentally friendly sealing performance. PVC sealing strip vendors have made great efforts in using fillers. Some manufacturers are pursuing greater output. , (Saving a little electricity) Use talc, heavy calcium and the like as fillers, which greatly increases the specific gravity of the sealing strip products (our users generally buy by kilograms and use them by length). The cost has been severely reduced and the quality has to be tried. 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, international name: EthyienePropyeneDieneMethyiene referred to as EPDM. 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. 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. The density of silicone sponge strip is divided into self-adhesive type and card slot type. It is used in different doors and windows. It is convenient and feasible in operation and installation. It does not react with any paint or cleaning agent. Customers do not need to worry about the integrity and aesthetics of doors and windows. When it is destroyed, the transmission parts: the spring base and the key or the fixing screw. Use your nose to smell if there is any peculiar smell. Normal PVC sealing strips will have a very pungent smell, while normal silicone rubber sealing strips will only have a little bit. The taste is mellow, the taste is very small, almost inaudible. Fourth, the impact resistance is good. Many people want to use foam sealing strips as cushioning materials, because the impact resistance of this product is very good, the physiological stability of the rubber sealing strips is very good, and the resistance to deformation is also very good. It is strong, not only resistant to ozone but also resistant to ultraviolet rays, so this product has been widely used, and it is inseparable from many places such as medical diversion, electronics, wire and cable, etc. , This product also has a very good advantage, that is, long service life. Any product is prone to damage during use. In order to reduce the probability of this phenomenon, it is necessary to carry out effective maintenance on the product. Because of its excellent physical and mechanical properties, it is often used in the manufacture of airplanes and cars. , Trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts. The main function of doors and windows is to seal, how to strengthen the seal, then the sealing strip plays a very critical role. The common sealing strips on the market are generally made of pvc material. The quality of the sealing strips mainly depends on the pros and cons of the plasticizers added. With the increase in the price of various chemical fields, the price of the sealing strips is constantly increasing. rise. Some irresponsible manufacturers cut corners in production for immediate benefit, which greatly affects the quality of their products, and at the same time brings great consumer hazards to consumers.
