The door and window seals are divided into glass sealant strip and wool strip.
Sealing strip tape is generally used on doors and windows, and there are special sealant slots on the pressing strip and doors and windows.
The main function is to wear sealant tape on both the pressing strip and the inner fan to make the glass and frame fan closer, thus ensuring the air tightness of doors and windows.
The installation position of the sealant strip should be flat, not crimped, not stretched, the joint should be less than 1MM, the type of sealant strip should match, too large to press the strip, too small to make the sealant strip easy to fall off, glass and fan body are not close, there will be gaps.
Sealing tape should be non-toxic. Tasteless and environmentally friendly special sealant strip.
The installation part of the wool strip is usually on doors and windows, around the frame fan or on the sealing bridge (windshield block), which enhances the sealing between the frame and the fan.
It is not only difficult to assemble, but also increase the moving resistance of doors and windows, especially the initial resistance of opening and the in-situ resistance of closing.
The size is too small, and the height of vertical wool strip is not enough to get out of the groove, which greatly reduces the sealing performance of (doors) and windows.
The top should be treated by silicification. The surface of the qualified top is straight and the bottom and vertical hair are smooth. No bending, no pitting on the back plate.
Bubble. Vertical hairs are firmly bonded to the bottom plate, with uniform sparseness and density, and are not easy to shed hairs.
