Silicone rubber strips for doors and windows

by:Kenna     2021-03-21
Door and window silicone rubber strips, door and window sealing strips, types and uses. Introduction: When we install doors and windows in our lives, 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. my country's automobile door sealing strip is one of the important parts of automobiles, and it is one of the important parts that determine the quality of the automobile. What are its more important roles in the automobile, foam sealing strip 1, The basic concept of the mechanical seal: the mechanical seal refers to the prevention of fluid by keeping 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 to prevent fluid from sliding. Leaking device. The sealing strip is a very important part in doors and windows. It can not only ensure the watertightness of the doors and windows, but also reduce the sound insulation. At the same time, it also has the effect of protection from external forces. However, due to the usual sun exposure, it will cause aging, shrinkage or deformation, so we must regularly Check and look at the specific gravity. If it is of good quality, the weight will be lighter. If it is a defective product, the weight will be heavier. This is because regular manufacturers use calcium carbonate as a filler and some manufacturers use talcum powder to increase the weight of the product. It is easy to distinguish good products from inferior products by looking at the specific gravity when buying. The auxiliary seal of the compensation ring is a metal bellows called a bellows mechanical seal. 2. The composition of the mechanical seal: There are mainly the following four types of components, a, the main seal: moving ring and static ring, b, the auxiliary seal: seal Ring, c, compression parts: spring, push ring, d, three. At the same time, put the PVC sealing strip and the silicone rubber sealing strip in the freezer compartment of the refrigerator. After a few hours, the PVC sealing strip will feel very stiff and easy to break. , There is no change in the physical properties of silicone rubber sealing strips. 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. If you have large cracks or serious aging of the door and window silicone rubber strips, then you don’t need to use the adhesive. It’s better to replace it with a new one. The replacement method is very simple, but in order to achieve good results, please be professional The personnel are updated, but 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, almost invisible. Since silicone rubber sealing strips are mainly produced using silicone rubber materials, they have better sealing performance than other sealing strips. It can also be used in some high-temperature environments. It has excellent weather resistance and can effectively It resists the invasion of natural factors, even if it is used for a long time, there will be no aging damage. Generally, the back of the silicone sealing strip is explained, so it can be effectively combined with other materials without using any adhesive. The materials are bonded together and have good sealing performance. No matter how long it is used in a high temperature environment, it will not fall off, so it has become the first choice for sealing materials. A small number of door and window companies in low-level price competition are still in use. Medium and high-end PVC strips can meet the standard indicators and have a relatively long service life. 5. Because of their excellent physical and mechanical properties, they are often used in the manufacture of airplanes and cars. , Trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts, 8℃, EPDM rubber has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical properties
