门窗密封条作用
Function of door and window sealing strip
密封胶条在塑钢门窗和断桥铝门窗及木门窗中起到了防水、密封及节能的重要作用，隔音、防尘、防冻、保暖。它必须具有很强的拉伸强度，良好的弹性，还需要比较好的耐温性和耐老化性。为了保证胶条与型材的紧固，胶条的断面结构尺寸必须与塑钢门窗型材匹配。密封胶条一般用于平开门窗、悬窗上、折叠门窗。主要作用为防尘、防虫、防水、隔音、密封等。
Sealant strip plays an important role in water-proof, sealing and energy-saving in plastic steel doors and windows, aluminum doors and windows with broken bridge and wooden doors and windows, with sound insulation, dust-proof, antifreeze and heat preservation. It must have a strong tensile strength, good elasticity, and also need better temperature resistance and aging resistance. In order to ensure the fastening of the rubber strip and the profile, the section structure size of the rubber strip must match the profile of the plastic steel door and window. The sealant strip is generally used for opening doors and windows horizontally, hanging windows and folding doors and windows. The main functions are dust-proof, insect proof, water-proof, sound insulation, sealing, etc.
毛条的安装部位一般在推拉窗(门)扇上，框扇的四周围或密封桥(档风块)上，增强框与扇之间的密封。毛条规格是影响推拉门窗和水密性能的重要因素，也是影响门窗开关力的重要因素。毛条规格过大或竖毛过高，不但装配困难，而且使门窗移动阻力增大，尤其是开启时的初阻力和关闭时的最后就位阻力较大。规格过小，或竖毛条高度不够，易脱出槽外，使门窗的密封性能大大降低。
The installation position of the wool strip is generally on the sliding window (door) leaf, around the frame leaf or on the sealing bridge (wind block), to enhance the sealing between the frame and the leaf. The size of the strip is not only an important factor affecting the performance of sliding doors and windows and water tightness, but also an important factor affecting the opening and closing force of doors and windows. It is not only difficult to assemble, but also increases the resistance of door and window movement, especially the initial resistance when opening and the last resistance when closing. The size is too small, or the height of the vertical strip is not enough, which is easy to get out of the groove, so that the sealing performance of the doors and windows is greatly reduced.
