Key points of quality control of sealing strip

Key points of quality control of sealing strip:

(1) The sealing strip can be directly installed on the doors and windows in the factory when the doors and windows are produced, but when the doors and windows are transported, attention must be paid to prevent warping and deformation.

(2) the selection of the variety and specification of the sealing strip should be matched with the type of door and window, the width of the gap and the part used, otherwise the expected effect will not be achieved.

(3) The sealing strip for the flat door window should be attached to the pressure surface of the door and window seam, and should not be attached to the shear surface, otherwise it will greatly shorten the life of the sealing strip

(4) Before pasting the sealing strip, the joints of doors and windows should be cleaned in advance, free of dust and dirt, and clean and dry.

(5) The fixed position of the sealing strip should be so that even if the joint is completely sealed, it is necessary to avoid the doors and windows being too tight or too loose.

(6) The sealing strip bonded with glue is coated with glue at the joint of the door and window frame. Depending on the type of glue, it often needs to be dried for a few minutes. The solvent in the glue volatilizes, and then the sealing strip is glued to be firm.
