Silicone oil absorbing expansion strip

Types and uses of silicone oil-absorbing expansion strips door and window sealing strips Introduction: When we install doors and windows in life, there will always be certain gaps, which cause the doors and windows 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. Doors and windows bring light and vitality to the living room. Doors and windows extend the limited space infinitely. Said ternary bc sealing strip (rubber EPDM)-suitable for special environments at -40°C-+160°C, and has superior ozone resistance Characteristics and anti-purple light characteristics and chemical solvent resistance characteristics, far beyond similar products, widely used in vehicle seals and building seals, in addition to various physical and chemical performance indicators in the field, our company has developed and designed hardy and heat for different fields of use. It also delivers foam and solids, with special properties that can meet the needs of the application. Four composite sealing strips-Shanghai Shenya Sealing Parts Co., Ltd. took the lead in the domestic development and production of composite sealing strips composed of 4 kinds of rubber materials, and covered with a thin layer of protection on the surface of the foam rubber (bubble tube) Layer glue, thereby further improving the service life of the seals, car sealing strips are classified according to the surface treatment state. After additional treatment, the surface of some sealing strips can be divided into flocking sealing strips; surface coating sealing strips; automotive sealing strips with fabric stickers Special function classification of sealing strips Some sealing strips have electronic intelligence functions, such as anti-pinch sealing strips. The characteristics of automobile sealing strips In the -40℃ low temperature resistance test, the sealing strips do not become hard or brittle, and still maintain softness and good adhesion of the strips, showing excellent cold resistance. The automotive sealing strips are mainly composed of It is made of ethylene propylene diene monomer (EPDM) rubber with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃). Contains unique metal clamps and tongue buckles, which are durable and easy to install. 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. Silicone oil-absorbing expansion strip car sealing strips can be classified into rubber sealing strips; plastic sealing strips; thermoplastic elastomer sealing strips. In use, many problems need our attention. When installing rubber sealing strips You can spray a little soapy water, this method can make your installation more convenient, and in the usual maintenance, avoid direct sunlight, and put it in a cool place, so that the rubber sealing strip can exert more performance , The use period can be extended. Energy-saving doors and windows are roughly composed of profiles, hardware, glass and EPDM door and window sealing strips, as well as several major modules of processing technology. The sealing strips are relatively low cost due to their proportion and are affected by some traditional concepts that do not pay attention to energy-saving standards for doors and windows. , Has been ignored by many door and window manufacturers, but we can’t help but admit that the sealing strip plays a vital role in the door and window system. What important role can EPDM sealing strip play in the door and window system? . Fourth, the aviation industry has also been used in the aviation industry, especially oxygen mask seals and waterproof covers, air-tight seals and shock absorption, etc. These aspects have a great demand for this material, in order to be able to increase For the comfort of the car, we also need to pay attention to some details, especially the car sealing strip. This product is also very useful and can effectively improve the comfort of use. Let’s take a look at the car sealing strip. What are the functions of it.
