How much high temperature does the silicone strip
resist? Types and uses of door and window sealing strip
s Introduction: When we install doors and windows in life, there will always be a fixed gap, which causes the door and window departments 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. 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. 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. These advantages are irreplaceable by other materials such as PVC. It can meet the needs of design and use for products with different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, and special performance requirements. Automobile sealing strip production process 1. Extrusion of rubber sealing strips for automobiles is extruded by a cold feed extruder. The extrusion head has a single head, a composite (double composite and multiple composite) head and a shear head. , The screw length to diameter ratio of the microwave vulcanizing extruder is generally 16, and the screw length to diameter ratio of the shear head vulcanizing extruder is greater than 20. 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. How much high temperature the silicone strip can withstand? Four composite sealing strips——Shanghai Shenya Sealing Parts Co., Ltd. is the first in China to develop and produce composite sealing strips composed of 4 kinds of rubber materials, which are coated on the surface of the foam rubber A thin protective layer of glue can further increase the service life of the seals. The automotive seals are classified according to the surface treatment state. After additional treatment, the surface of the seals can be divided into flocking seals; surface coating seals; yes The special function classification of the automobile sealing strip of the fabric patch seal Some sealing strips have electronic intelligence functions, such as anti-pinch seals. Silicone sealing strips can also be glued to materials with a smooth surface because of its high shock resistance and waterproof performance. According to the composite structure of rubber materials, automotive sealing strips can be divided into pure rubber sealing strips-composed of a single type of rubber; 2. Composite sealing strip-composed of dense rubber and foam sponge rubber, often containing metal framework material in the axial direction inside the dense rubber
