Types and uses of door and window sealing strip
s for silicone slitting machine 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. For this reason, the GB12002-89 'Sealing Strips for Plastic Doors and Windows' was formulated very early to regulate 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 took the lead in the domestic development and production of composite sealing strips composed of 4 kinds of rubber materials, and covered with a thin protective layer of rubber on the surface of the foam rubber (bubble tube). Thereby further improving the service life of the seal. The characteristics of sound insulation, heat preservation, sealing, impact resistance and environmental protection have attracted more and more consumers' attention. 'Functionality' has long been a functional, rational and reliable image of German design, especially The whole product is in harmony and unity at the level of technology, function, logic and sense of order. 'The covered sealing strip structure makes the door leaf and the door sleeve tight and seamless, blocking sound penetration, and has strong resilience and sound insulation. In general, EPDM sealing strips can be used stably for more than ten years. With the continuous development and maturity of thermoplastic elastomer (TPE) technology, the application fields continue to expand. According to the classification of vulcanization (1) Discontinuous vulcanization method (will be After the extruded rubber strip is cut to a certain length, it is put into a vulcanizing tank to vulcanize, and the semi-finished product of the extruded rubber strip is vulcanized in the model); (2) Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, heat Several methods such as continuous air vulcanization). 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 have high requirements for materials and must first have a 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 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. It is used to install on the sash of push-type doors and windows to seal the gap between the frame and the sash. The specifications of the tops can greatly affect the watertight performance of the doors and windows, and also affect the opening and closing of the doors and windows. The specifications of the tops If it is too large, or the vertical hair is too high, it will be very difficult to assemble, and after assembly, the resistance of the door and window will increase when moving. If the fire specification is too small, or the vertical hair is too low Yes, doors and windows are prone to bracket phenomenon, which reduces the sealing performance of doors and windows. There are generally two types of tops that have been siliconized and those that have not been siliconized. Generally, the use effect after treatment will be better. The quality of qualified tops has the following characteristics : The appearance has no obvious defects, the surface is straight, the bottom plate and vertical hair are relatively smooth, there is no bending phenomenon, and there are no pitting and other problems on the bottom plate, which meets the size requirements. The silicone slitting machine works very well on various electrical cabinets. The key role is the main performance of EPDM products: the product is non-toxic, environmentally friendly, resistant to aging, high temperature, stable performance, and can maintain good performance in summer and winter. Considering the process performance of commonly used rubber materials, sometimes It is also necessary to use combined rubber, such as the combined use of natural rubber (NR) and CR and styrene butadiene rubber (SBR) or polyethylene (PE), EPDM and NR rubber-plastic combined type to improve ozone resistance. Anti-collision countless times There will be 'touch!' when you close the door and cabinet door. bump! ……' The impact sound will affect your daily mood and mood after a long time. The new PU foam sealing strip has super resilience, no deformation, tasteless and environmentally friendly, and the sound insulation and anti-collision effect is more significant. It is 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-248°f (-40°C-120°C) °F-260°f(-40°C-126., the weight of the lightweight foam sealing strip is very light, which brings great convenience to the transportation and use process, and the strength and toughness of the product is also very good , Can be used in any environment, can work for a long time in a high temperature and low temperature environment, these advantages have expanded the application range of the product, then, what are the main application ranges What?
