Types and uses of silicone solid round 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. Energy-saving doors and windows are roughly composed of profiles, hardware, glass and EPDM door and window sealing strips, as well as several major modules of processing technology. The sealing strips are relatively low cost due to their proportion and are affected by some traditional concepts that do not pay attention to energy-saving standards for doors and windows. , Has been ignored by many door and window manufacturers, but we can’t help but admit that the sealing strip plays a vital role in the door and window system. What important role can EPDM sealing strip play in the door and window system? . Fourth, the impact resistance is good. Many people want to use foam sealing strips as cushioning materials, because the impact resistance of this product is very good, the physiological stability of the rubber sealing strips is very good, and the resistance to deformation is also very good. It is strong, not only resistant to ozone but also resistant to ultraviolet rays, so this product has been widely used, and it is inseparable from many places such as medical diversion, electronics, wire and cable, etc. , This product also has a very good advantage, that is, long service life. 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 for 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. Sealing strips play a role in sealing and waterproofing plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Function. The sealing strip has very high requirements on the material. First, it must have strong stretching ability and elasticity, as well as better temperature resistance and aging resistance. At the same time, in order to ensure the close contact between the sealing strip and the profile, the sealing strip’s The cross-sectional structure must match the door and window profile, which is generally suitable for hanging windows and folding doors and windows. The top is generally used to install on the fan of the push-type door and window to seal the gap between the frame and the fan. The specifications of the top can be very different. It affects the watertight performance of doors and windows to a large extent, and also affects 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, it will be the door and window. When moving, the resistance increases. 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. The wool strips are generally siliconized and not siliconized. Two types, generally after treatment, the use effect will be better. The quality qualified tops have the following characteristics: no obvious defects in appearance, straight surface, smooth bottom plate and vertical hairs, no bending phenomenon, and no pitting and no pitting on the bottom plate. Other issues are in compliance with the size requirements. Silicone solid round car sealing strip introduction The sealing performance is an important indicator of the quality of the car, and the car sealing strip product is one of the important parts that determine the quality of this indicator. It is widely used in front and rear windshields, doors, windows, engine compartments, trunks and other body parts of automobiles to fill the gaps between body parts. It has the functions of shock absorption, waterproof, dustproof, sound insulation, decoration, etc. And the whole vehicle plays a maintenance role. There are many ways to classify automobile sealing strip products, usually according to the title of the device part (component), the type of data, the number of composite materials, the working characteristics and other factors. These advantages are PVC, etc. Other materials are irreplaceable. For products with different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, and special performance requirements, they can all meet the needs of design and use. Automobile sealing strip production process 1 , Extrusion of rubber sealing strips for automobiles is extruded by cold feed extruder. The extruder head has single head, composite (double composite and multi composite) head and shear head. Among them, microwave vulcanization extruder The screw length-to-diameter ratio is generally 16, and the screw length-to-diameter ratio of the shearing head vulcanizing extruder is greater than 20. The elastomer TPE water bleaching sealant is applied to the door and window sealing strip
