The installation of the sealing strip plays an important role in waterproofing, sealing and energy saving, sound insulation, dustproof, antifreeze, and warmth. It must have strong tensile strength, good elasticity, and better temperature resistance and aging resistance. The specific installation steps are as follows: The installation position of the top is generally on the door and window sash, around the frame fan or on the sealing bridge (wind block) to enhance the seal between the frame and the fan. Excessively large tops or high vertical hairs not only make assembly difficult, but also increase the movement resistance of doors and windows, especially the initial resistance of opening and the resistance of closing in place. If the specifications are too small, the height of the vertical tops is not enough to easily fall out of the groove, which greatly reduces the sealing performance of the window. The tops need to be siliconized, and the tops with qualified quality have a straight surface, smooth base and vertical hairs. No bending, no pitting on the base plate. bubble. The vertical hair is firmly bonded to the base plate, and the density is uniform, and it is not easy to shed hair.
