Inflatable silicone rubber strip

Silicone inflatable rubber strip door and window sealing strip type and use Introduction: When we install doors and windows in life, there will always be a fixed gap, which causes the door and window department 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. It is made of soft and elastic, non-toxic and odorless after special processing, and can withstand 200℃ high temperature, high pressure and repeated cooking. It is used for thermal insulation and insulation of electrical products, internal pipes of drinking water systems, industrial refrigeration equipment, and gas The internal connection of appliances, the sealing of machinery, lamps and other products, and the performance of sealing strips greatly affect the air-tightness, water-tightness, heat loss and other important performance indicators of doors and windows, and the firmness of doors and windows. The surface of the plastic steel door and window sealing strip is smooth and clean, which not only has excellent sealing and waterproof performance, but also plays a beautiful decorative role. In terms of material selection, manufacturers with higher requirements generally choose EPDM rubber or thermoplastic EPDM rubber, according to the location And use classification (1) window glass sealing strip; (2) door sealing strip; (3) decorative strip, molding strip; (4) other sealing strips (trunk lid sealing strip, engine cover sealing strip, water tank sealing strip, Emergency door sealing strip, etc.). It plays a key role in various electrical cabinets. The main performance of EPDM products: the product is non-toxic, environmentally friendly, resistant to aging and high temperature, stable performance, and can maintain good performance in summer and winter. The process performance of commonly used rubber compounds sometimes requires the use of combined rubber, such as the combined use of natural rubber (NR) with CR and styrene butadiene rubber (SBR) or the combined use of polyethylene (PE), EPDM and NR rubber to improve resistance. Ozone. 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 inflatable rubber strip B, salt bath continuous vulcanization sealing strip: salt bath vulcanization adopts a nitrite-containing salt bath system, which causes great environmental pollution and has been gradually eliminated. C, classified by section shape, can be divided into solid core products ( Round, square, flat cross-section shapes), hollow products and metal rubber composite products, EPDM rubber sealing strips are much stronger than PVC strips in terms of sealing elasticity and durability, but because of the need for microwave vulcanization lines Shaped, processing energy consumption is high, usually more than 20 times that of PVC processing, the product cannot be reused, is not environmentally friendly, and is not a recommended product. If your cracks are large or the aging degree is serious, then you don’t need to use the adhesive anymore. It is more convenient to replace with a new one. The replacement method is very simple, but in order to have a good effect, please ask a professional to update it. However, most people choose PVC material, so what should people pay attention to when buying sealing strips? First of all, put the product on your nose and smell it. If it is made of normal PVC material, it will have a little brewing smell, but the smell is very small, and it can hardly be smelled. It is divided into self-adhesive type and card slot type. It is used in different doors and windows. It is more convenient and feasible in operation and installation. What is the performance advantage of the coated sealing strip? 1. Compression deformation test: 50% compression rate at 70℃ continuous compression 22 hours, deformation rate ≤10%2, compression force test, under 25% compression rate, apply a force of 15N/100mm, compression rate ≤10N3, temperature range test: from -40℃ to 90℃, the sealing performance is not obvious Change 4. Thermal conductivity K value test: K value ≤ 0 at 0°C.
