Silicone extruder price Types and uses of door and window sealing strip
s Introduction: In our life, when we install doors and windows, there will always be a fixed gap, which causes the door and window departments 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. Some developed countries attach great importance to the sealing of the family, even if the balcony is tight and accurate, they do not forget to have sealing strips. There are many types of door and window sealing strips, some are soft rubber sheets, some are foam plastics, and some are chemical fibers. The materials are different. It can also be used in different locations. Secondly, if the door and window sealing strips are in contact with the door in the hot summer season, the color of the door and window will be degraded and yellowed due to the sunlight. This is too bad for the beauty. You must go to a regular store to buy . Humanization 'In the past, the tradition has always paid more attention to materials and workmanship, ignoring the attention to humanization in use. What are the performance advantages of coated seals? 1. Compression deformation test: 50% compression rate at 70°C continues to compress 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. Heat conduction K value test: K value ≤ 0 at 0°C. Third, the structure of good water absorption is very characteristic, it adopts the structure of independent bubbles, so the water absorption performance of the product is very good, so It will achieve the effect of moisture resistance. This product has many advantages. Not only is the transparent effect good, but the appearance of the product is also very smooth. It is a very soft and elastic product, and this product does not have any Odor, it also has good high temperature resistance and low temperature resistance. The use of this product is not prone to aging and deformation. Then, what are the characteristics and uses of rubber sealing strips. Sealing strips are used in plastic steel doors and windows, Aluminum alloy doors and windows and wooden doors and windows play a role in sealing and waterproofing. 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. It is generally suitable for hanging windows and folding doors and windows. The wool strip is generally used to install on the fan of the push-type door and window to seal the frame The gap between the top and the fan. The size of the top can greatly affect the watertight performance of doors and windows, and also affect 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 in the assembly It is very difficult, and after assembly, 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 doors and windows are prone to bracketing, which reduces the sealing of the doors and windows. There are generally two types of tops that have been silicified and those that have not been silicified. Generally, the treated ones will have better results. The qualified tops have the following characteristics: no obvious defects in appearance, straight surface, and comparison of bottom and vertical hairs Smooth, no bending, and no pitting and other problems on the bottom plate, in line with the size regulations. The price of silicone strip
extruder is one of the important parts of the car in China, which determines the quality of the car. One of the important parts of the index, what are the more important roles it has in the entire automobile? Foam sealing strip 1. The basic concept of mechanical seal: mechanical seal refers to the fluid flow in at least one pair of end faces perpendicular to the axis of rotation. The pressure and the elastic force (or magnetic force) of the compensating mechanism and the auxiliary seal are kept close together and slide relatively to prevent fluid leakage. In fact, there are many places in our lives that are inseparable from this product. Because its use effect is very good, friends who don’t know can take a look at the characteristics of EPDM sealing strip with me. Third, the ozone resistance of ozone-resistant products is very good and can be completely Violent Exposed to work in the air, so that the superiority of the product is more prominent, the anti-ultraviolet radiation effect of EPDM sealing strip is also very good, and it also has excellent physical and mechanical properties, so it is often used for manufacturing Airplanes and trains, cars, etc. 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.
