How much is the anti-theft door sealing strip
per square meter? China’s automobile door sealing strip is one of the important parts of automobiles and one of the important parts that determine the quality of the automobile. What are the more important parts of the automobile? Function, foam sealing strip 1. The basic concept of mechanical seal: mechanical seal is maintained by at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal. A device that prevents fluid leakage by sticking and sliding relative to each other. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be certain gaps, which will cause the doors and windows 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. 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. For car sealing strips, we must pay more attention to maintenance and master the correct maintenance method, otherwise the maintenance effect will not be achieved. Let us understand the importance of car sealing strip maintenance. The characteristics of the product The elasticity and compression resistance of the strip are very good, and it also has good resistance to aging, ozone and chemical effects, etc., making the product very strong and durable during use, and it is also very convenient to install of. There is no obvious change in the physical properties of silicone rubber at -50°C. Fifth, depending on the specific gravity, how many meters can be produced per kilogram, the PVC sealing strip with heavy calcium added, you can stretch it back and forth several times by hand, and a small amount of white powder will appear on the surface. The density of PVC sealing strips should be 1,4-1,6. Silicone rubber sealing strips should be filled with nano-scale silica as a filling and reinforcing effect. The texture is light and the density ratio is between 1,1-1,25. The material rate is 20% higher than that of PVC sealing strips. 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. Play a key role in electrical cabinets. The skeleton seal is composed of dense rubber, foam rubber and steel wire film. The cabinet sealing strips are mainly used for cabinets, electrical cabinets, and machinery. They are mainly used for fixing effects and sound insulation, waterproofing, and anti-corrosion. Dust, airtight, recommended temperature range: PVC material 20°F-150°f(-29c-65, a door may not be beautiful, but a sealing strip must be installed to ensure sound insulation, temperature and sealing performance. It can be seen that, The necessity of sealing strips for doors. In doors and windows, it is one of the inconspicuous small accessories, but it directly affects people's living environment. Based on years of professional experience in door and window sealing products and understanding of the market and customer needs, the introduction of foreign advanced technology independently Developed the world's advanced sealing products to meet domestic and foreign mid- to high-end customers: the pursuit of sealing will never stop, and we are also maintaining the original advantages, so that you 'must have it'! The mute contains special sound-absorbing cotton, which can It can effectively absorb the noise that leaks into the room from the movable window. It has better sound insulation performance than ordinary sealing strips, and can improve the sound insulation performance of doors and windows by 35%. Among them, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-section is designed to It’s important. First of all, the shape and size of the sealing lip are designed. The sealing lips on both sides should contact the glass from both sides of the car window glass with the same and appropriate force.
