Specifications are affected tops watertight sliding doors and an important factor in the performance , but also affect the switching power windows important factor . Tops specification is too large or vertical hair too high, not only difficult to assemble , but make doors and windows mobile resistance increases , especially when the initial resistance is turned on and off when the last place greater resistance . Size is too small, or the vertical tops high enough, easy to prolapse outside the tank , so that doors and windows sealing performance is greatly reduced. Siliconized tops subject to satisfactory quality appearance of the surface flat tops , bottom and vertical hair smooth, no bending , no pitting on the floor , in line 0.20MM requirements.
From the above, we can see that the sealing strip in steel doors and windows and aluminum doors and windows broken bridge played a waterproof seal , and the important role of energy-saving , noise , dust, frost, warm. It must have a strong tensile strength , good flexibility , but also good heat resistance and resistance to aging.
