The type and purpose of the unqualified door and window sealing strip
s when the silica gel strips are compressed and deformed. 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 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. Among the raw materials for sealing strips, EPDM, the main raw material used in the past, is also constantly updated and developed. The new EPDM with excellent physical properties and good processing properties can control the long-chain branching in the molecule and make it The vulcanization performance is better, and the extrusion speed and the output of the product can be improved. These materials have the excellent engineering properties of elastomers and the excellent characteristics of plastics, which are convenient for processing and can be recycled and reused. These materials are gradually replacing EPDM. Products. 'Specialization' originated from Germany and has been popular in the European market for a long time. It is famous for its environmentally friendly sealing performance. The sound insulation, heat preservation, sealing, impact resistance and environmental protection characteristics of the coated sealing strip have been more and more Many consumers pay attention to 'functionality'. For a long time, German design has always been a well-functioning, rational and reliable image, especially the harmony and unity of the entire product in terms of technology, function, logic and sense of order. The sealing strip structure makes the door leaf and the door sleeve tight and seamless, has stronger sound penetration resistance, and has strong resilience, sound insulation and environmental protection. For this reason, GB12002-89 'Seal for Plastic Doors and Windows' was formulated very early 'Article' standard to standardize the production and inspection of sealing strips. However, the quality and price of rubber and plastic sealing strips for doors and windows in the building materials market are very confusing. Four composite sealing strips-our company takes the lead in the development and production of domestic sealing strips. The composite sealing strip composed of 4 kinds of rubber materials is covered with a thin protective layer of glue on the surface of the foam rubber (bubble tube) to further improve the service life of the seal. The sealing strip is used in plastic steel doors and windows, aluminum Alloy 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, for To ensure 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. 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 gap between the fans. The size of the top can greatly affect the watertight performance of doors and windows, and 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 It is difficult, and after assembly, the resistance of the 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 generally two types that have been silicified and those that have not been silicified. Generally, the use effect after treatment will be better. The quality qualified tops have the following characteristics: the appearance is not obvious, the surface is straight, the bottom plate and the vertical hairs are relatively smooth , No bending phenomenon, and no pitting and other problems on the bottom plate, in line with the size requirements. The silicone strip is unqualified and durable in compression and deformation. It maintains stable performance and long service life in different environments, anti-aging and wear-resistant , The surface does not wrinkle, does not stretch, does not stick to the paint surface, is not affected by high temperature, dust, mildew, and anti-ultraviolet and ozone erosion. Our value to you starts from your experience, durable and new. It is the user’s real experience. The beautifully wrapped PU sealing strip is green and environmentally friendly, and it is stylishly sealed; it perfectly solves the contradiction between sealing and sound insulation, and achieves the dual effect of sealing and sound insulation; doors and windows are perfectly matched with products. Of course, rubber sealing strips can also be used in medical Application, no matter what kind of application the product is used in, the effect is very good, it can meet everyone's needs, which brings you a lot of help, the use effect of rubber sealing strip is very ideal, and also The color and specifications can be customized according to the needs of customers, and the packaging requirements are also carried out according to the needs of the installation customers, so choosing this product can bring great convenience to everyone. The 'specialized' covered sealing strip originated from Germany and has been popular in the European market for a long time. It is famous for its environmentally friendly sealing performance. PVC sealing strip vendors have made great efforts in using fillers. Some manufacturers are pursuing greater output. , (Saving a little electricity) Use talc, heavy calcium and the like as fillers, which greatly increases the specific gravity of the sealing strip products (our users generally buy by kilograms and use them by length). The cost has been severely reduced and the quality has to be tried.
