stores. 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 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. Any product is prone to damage during use. In order to reduce the probability of this phenomenon, it is necessary to carry out effective maintenance on the product. Because of its excellent physical and mechanical properties, it is 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. 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. It is suitable for all kinds of doors, windows, etc. 2. Cabinet sealing strips have developed their own characteristics based on the use of electric cabinets and based on 20 years of experience in the development of sealing strips, which have good sealing performance. , Waterproof, fire-proof, insect-proof, windproof, light-proof, anti-collision and long service life, etc. 1. Three-composite steel frame, not easy to deform and shrink, firm assembly, and good sealing 2. Sealing strips for doors, windows and curtain walls, products It has good elasticity, resistance to migration, and can effectively block noise, dust, and weather. 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 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. Xingtai silica gel strip store automobile sound insulation and anti-collision strips are divided into 3M adhesive small D-shaped sealing strip, 3M adhesive large D-shaped sealing strip, 3M adhesive large P-shaped sealing strip, A, microwave continuous vulcanization composite sealing strip: microwave vulcanization technology It is a production technology that was applied and widely promoted after the foreign energy crisis in the 1970s. The use of microwave continuous vulcanization technology can not only produce composite strips of metal core, solid rubber and sponge rubber, but also save energy and improve work. The efficiency is superior to other continuous vulcanization equipment. In fact, there are many places in our lives that cannot be separated from this product, because its use effect is very good, friends who don’t know can join me to take a look at the characteristics of EPDM sealing strip. Third, ozone resistance The ozone resistance of the product is very good, and it can be completely exposed to the air to work, so that the superiority of the product is more prominent, and the anti-ultraviolet radiation effect of the EPDM sealing strip is also very good. Yes, but also has excellent physical and mechanical properties, so it is often used to make airplanes, trains, cars, and so on. Sealing strips are made of rubber, paper, metal, plastic and other materials. Low-end products use waste materials, substitute plasticizers and high filling levels, so that the strips have poor elasticity, easy to harden, and have a nasty smell. , Easy to migrate, yellowing the frame material, short service life
