Types and uses of silicone seals for door and window seals 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. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass contact the glass. Check regularly for cracks and breaks. If you find that the sealing strip is broken, you can find an adhesive to repair it. The adhesive here is for special use. It is bonded so that it is not difficult to repair the cracks. 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. Since silicone rubber seals are mainly produced using silicone rubber materials, they are better than others The sealing strip made of material has better sealing performance, and can also be used in some high-temperature environments. It has excellent weather resistance and can effectively resist the invasion of natural factors. Even if it is used for a long time, it will not appear aging damage. Generally, the back of the silicone sealing strip is provided with an explanation, so it can be effectively bonded to other materials without using any adhesive, and it also has a good sealing performance, whether it is at high temperatures. How long it is used in the environment, it will not fall off, so it has become the primary choice for sealing materials. Sealing strips play a role in sealing and waterproofing plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips are for materials. The requirements are very high. First of all, it must have strong tensile ability 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 be in line with the door and window profile. It 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 top can greatly affect the performance of the door and window. Watertight performance will also affect 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 assembly, the resistance of the doors and windows will change when they move. Large. If the fire specification is too small, or the vertical hair is too low, the door and window are prone to bracket phenomenon, which reduces the sealing performance of the door and window. There are two types of wool strips that have been siliconized and those that have not been siliconized. The use effect of the treatment will be better. The quality qualified top has the following characteristics: no obvious defects in appearance, straight surface, smooth bottom plate and vertical hair, no bending phenomenon, no pitting and other problems on the bottom plate, and conform to the size In addition, the material proportion of this type of product (above 1, 4) is equivalent to that of PVC (low-end vulcanized EPDM rubber strip has a larger proportion). The window rate is similar to that of PVC rubber strip, and the cost of use is relatively biased. It is difficult for door and window companies to accept. Sealing strips can be classified according to several methods such as cross-sectional shape, vulcanization method, application location and purpose, and materials used. Product characteristics 1) Light bulk density, large expansion and contraction strength, and no water absorption (replacement of traditional three oil Four felt, asphalt wood fir board and other materials). , Elastomer TPE water floating sealing strip is applied to door and window sealing strip, mainly divided into: plastic steel door and window sealing strip, aluminum alloy door and window sealing strip, wooden door sealing strip, cold storage door sealing strip, grain storage door sealing strip, flame retardant door and window sealing strip , Glass sealing strips, automatic revolving door sealing strips, building door sealing strips, curtain wall sealing strips, etc., the so-called sealing strips with pores inside, this product is formed at one time through the microwave vulcanization process during production. Therefore, the surface is not only very smooth, but also has good aesthetics. It will not leave any joint marks during production. At the same time, the elasticity and resistance to compression deformation are also very strong. Let us take a detailed look at the hair The characteristics of the bubble sealing strip. New types of thermoplastic elastomers, such as TPO and TPV, are used more and more in automotive sealing strips. According to the type classification, D-type sealing strips are divided into large D-type, small D-type sealing strip, P-type sealing strip and E-type. Sealing strip, but with the development of the automobile industry in recent years, a domestic-made Wonder double-sided adhesive has taken up more and more market shares. It overcomes the shortcomings of 3M adhesive construction that is not resistant to cold, simple construction, and durable adhesiveness. The effect of the previous temperature on the life of the sealing strip!
