Silicone sealing strip for doors and windows is an important building material, which plays a key role in the installation of doors and windows. This kind of sealing strip has excellent characteristics, not only can effectively prevent the penetration of water, gas and noise, but also can provide good heat preservation and sound insulation effect.
Rubber strip technical indicators:
The standard "Sealing Strip for Building Doors and Windows" (JG/T187-2006) has been released and published and has been officially implemented since June 1, 2007. In order to facilitate door and window manufacturers, real estate users, developers, etc. to understand the standard requirements of door and window sealing strips, and correctly select qualified products to ensure the sealing performance of doors and windows to ensure the realization of the overall energy-saving requirements of buildings, the main performance indicators of materials and products in the standard of "Sealing Strip for Building Doors and Windows" are introduced:Requirements
The appearance should be smooth, no distortion, no cracks, no bubbles, no obvious impurities and other defects on the surface, uniform color.
Dimensional tolerance: The sectional dimensional tolerance of the sealing strip shall be in accordance with Table 2 in GB/T3672.1-2000. The assembly dimension shall be in accordance with Grade E1, and the non-assembly dimension shall be in accordance with Grade E2. The geometric tolerance of the sealing strip shall be in accordance with Grade N in GB/T3672.1-2000.
