Silicone protective strips, if your cracks are large or aging is serious, then you don’t need to use the adhesive. It is better to replace with a new one, which is more trouble-free. The method of replacement is very simple, but in order to have a good effect, please be professional. The personnel are updated, but most people choose PVC material, so what should people pay attention to when buying sealing strip
s? 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, and it can hardly be smelled. 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. The heat resistance and cold resistance, insulation and conductivity, as well as flame retardancy are very good. It can be used at 100-120℃ for a long time, and it can remain effective for a long period of time at 140-150℃. Its physical properties can withstand high temperatures of 230-260℃ in a short period of time, and it can delay the effect of sudden accidents in urban buildings; coupled with the use of special formulas, EPDM rubber feels similar at -50℃ to 150℃ , This has created a high-efficiency work performance for the production site installation. The product is environmentally friendly, easy to construct, and has good anti-seepage, anti-leakage and water-stop effects. 2) Corrosion resistance, aging resistance, high and low temperature resistance +80℃~-45℃, no flow, no deformation, no embrittlement, long service life, thermoplastic EPDM rubber sealing strip The sealing strip is a new material developed on the basis of imported technology and domestic independent research and development in recent years. It is mainly used for automotive door and window sealing strips. In recent years, it has been used for building door and window sealing. Its outstanding advantages are: ①The performance and service life are equivalent to those of vulcanized EPDM rubber 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. If the smell is great, it is not a regular PVC. The sealing strip is a frequently used product, which is made according to a special process and special materials. The function of the sealing strip is to play a sealing role. It is an indispensable part of many products that can effectively protect the performance of utensils. It can be said that it is indispensable and plays a great role. We cannot ignore it. Another point is that it does not absorb water, so it It is also a material that replaces traditional asphalt. It is not precisely because of its water resistance that it will not be saturated under high water pressure. Another point is that it is more environmentally friendly on the entire material and will not cause any damage to the human body. s damage. Nowadays, cars are also very common and have become our main transportation tool. The basic function can fill some gaps in the body, so that good shock absorption and waterproof effects can be achieved. Features: 1, three yuan Ethylene-propylene has excellent weather resistance, weather resistance refers to long-term resistance to severe cold, heat, dryness, and humidity, and excellent corrosion resistance to rain and snow erosion, which can completely extend the service life of the rubber strip
; 2. Heat aging resistance refers to strong resistance to hot air aging. Durable maintains stable performance and long service life in different environments,
