Abstract
The invention discloses a processing method and a processing device for a waterproof paper-faced gypsum board. The method includes unfolding an upper paper surface and a lower paper surface, and the upper paper surface and the lower paper surface are both common face-protecting papers; The outer surface of the lower paper surface and the lower paper surface are sprayed with polymer waterproofing agent to form a hydrophobic film on the surface of the board after forming; the gypsum wet material used to form the gypsum board core is added to the lower paper surface; the upper paper surface, gypsum board core and The lower paper surface forms a shaped board. By spraying the polymer waterproof agent on the ordinary face paper (upper paper surface and lower paper surface), instead of adding waterproof agent to the wet material of the gypsum board and purchasing special waterproof face paper, and can Overcome the defects of board foaming caused by the high air permeability and unevenness of the protective paper in the production process of waterproof paper-faced gypsum board, improve the qualified rate of finished boards, reduce production costs and simplify the production process.
