Silicone extruder manufacturer

Types and uses of door and window sealing strips for silicone extruder manufacturers. 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. For this reason, the GB12002-89 'Sealing Strips for Plastic Doors and Windows' was formulated very early 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 strip-Our company takes the lead in the domestic development and production of a composite sealing strip composed of 4 kinds of rubber materials, and a thin protective layer of glue is coated on the surface of the foam rubber (bubble tube). Thereby further improving the service life of the seal. According to the name of the installation part (component), the classification includes: engine cover sealing strip (HOOD), which can be divided into front, side and rear; door frame sealing strip (DOORSEAL); front and rear wind window sealing strip (WINDOWSCREEN); Side window sealing strip (SIDEWINDOWSEALING); sunroof sealing strip (SUNROOFSEALING); door first road sealing strip (PRIMARYDOORSEAL); window guide groove sealing strip (GLASSRUNCHANNEL); inside and outside strips (water cut) (WAISTLINE); trunk sealing strip (TRUNKSEAL) ; Anti-noise sealing strip (ANTI-NOISE); Dust-proof strip (ANTI-DUST), etc. 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 obvious, 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-section structure must match the profile of the door and window, 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-position 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 in assembly, and after assembly, it will also be doors and windows. When moving, the resistance becomes larger. 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 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 no pitting on the bottom plate. Other issues are in compliance with the size requirements. Silicone strip extruders are also called fire-resistant silicone sealing strips and fire-resistant self-extinguishing silicone sealing strips. They are known for their good flame-retardant and self-extinguishing properties. The main process flow is first The high-quality silicone material is used to make a molded silicone strip through a large extruder, and then it must be vulcanized and dried at high room temperature. Compared with the general silicone strip, the high temperature and flame-retardant silicone strip is different in that it needs to be in the formula Flame-retardant powder is added to the silicone strip, which has super flame-retardant and fire-retardant properties, and plays a certain safety guarantee in the sealing of electronic appliances, so many people also call it a fire-proof sealing strip. For this reason. , The standard GB12002-89 'Sealing Strips for Plastic Doors and Windows' was formulated very early 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. Composite sealing strips-our company takes the lead in developing and producing composite sealing strips composed of 4 kinds of rubber materials in China, and a thin protective layer of rubber is coated on the surface of the foam rubber (bubble tube), thus further Improve the service life of seals. In some developed countries, family seals are attached great importance, even if the balcony is tight and accurate, they do not forget to have sealing strips. There are many types of door and window sealing strips, some are soft rubber sheets, some are foamed plastics, and Some are chemical fiber, the material is not The same can also be applied to different locations. Secondly, if the door and window sealing strips contact the door in the hot summer season, the color will be degraded and yellowed due to sunlight.
