Silicone strip bonding step Types and uses of door and window sealing strips Introduction: When we install doors and windows in life, 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. Of course, rubber sealing strips can also be used in medical applications. No matter what kind of application the product is used in, the use effect is very good. It can meet everyone's needs and bring you a lot of help. The use effect of the sealing strip is very ideal, and the color and specifications can be customized according to the needs of customers. The packaging requirements are also installed according to the needs of the customers, so choosing this product can bring you a lot Convenience. Anti-collision. There will be 'bump! Bump!...' when you close the door and cabinet door for countless times. Will it affect your mood and mood every day after a long time? The new PU foam sealing strip has super resilience. , No deformation, odorless, environmental protection, sound insulation and anti-collision effect is more significant, worth having, 5) EPDM rubber material 40°F-248°f (-40°C-120°C), nitrile-butadiene rubber material 40° F-248°f (-40°C-120°C), silicone rubber material 40°F-260°f (-40°C-126. There is no obvious change in the physical properties of silicone rubber at -50°C. Five, depending on the specific gravity, per kilogram How many meters can be produced, add the heavy calcium PVC sealing strip, you stretch it back and forth several times by hand, a small amount of white powder will appear on the surface, the density of the PVC sealing strip should be 1,4-1,6, and the silicone rubber seal The strip uses nano-scale silica as a filling and reinforcing effect, with a light texture and a density ratio of 1,1-1,25, so the material yield is 20% higher than that of PVC sealing strips. Sealing strips are used in plastic steel doors and windows, aluminum alloys Doors and windows and wooden doors and windows play a role in sealing and waterproofing. Sealing strips have 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 sealing strip is in close contact with the profile. The cross-sectional structure of the sealing strip must match the profile of the door and window. It is generally suitable for hanging windows and folding doors and windows. The wool strip is generally used to install on the fan of the push-type door and window to seal the frame and the fan. The gap between the tops. 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 specifications of the tops are too large, or the vertical hairs are too high, it will be very difficult to assemble And after assembly, 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, the doors and windows are prone to bracketing, which reduces the airtightness of the doors and windows. There are two types that have been silicified and those that have not been silicified. Generally, the use effect after treatment will be better. The quality of the top has the following characteristics: no obvious defects in appearance, straight surface, smooth bottom plate and vertical hair, No bending phenomenon, and no pitting and other problems on the bottom plate, in line with the size requirements. Silicone strip bonding step 6) classification and function, high-quality sealing strips, whether in terms of appearance, internal quality or later use, Will improve the overall style and performance of the door, and the wrapped seal is a modern development trend, humanized. 'In the past, traditional seals have always paid more attention to materials and workmanship, ignoring the attention to humanization in use. The improvement of people's living standards, the improvement of housing conditions and the high importance of people's home decoration, the privacy of indoor rooms, sound insulation and sealing effects have attracted more and more people's attention. And this kind of EPDM sealing strip is in the design, It is often more advanced. It has an independent bubble structure, so that it can form a good sealing bond rate, and all the bubbles have reached a uniform distribution, which can play a good expansion and contraction performance. , And it is precisely because of this that it can achieve It has the superior performance of no flow, no deformation, no cracking and so on. It cannot be combined with many uneven materials on the contact material used except for the plane. , The weight of the lightweight foam sealing strip is very light, which brings great convenience to the transportation and use process, and the product's strength and toughness are also very good. It can be used in any environment and can be used at very high temperatures. Working for a long time in a high and low temperature environment, these advantages have expanded the application range of the product. Then, what are the main application areas? 1. Modern industry and defense industry are not only very common in life, but also can be used in modern industry and defense industry to help companies produce products. The main function of doors and windows is to seal, how to strengthen the seal, then the sealing strip plays a very critical role. The common sealing strips on the market are generally made of pvc material. The quality of the sealing strips mainly depends on the pros and cons of the plasticizers added. With the increase in the price of various chemical fields, the price of the sealing strips is constantly increasing. rise.
