Problems solved by technology

[0002] The existing waterproof paper-faced gypsum board achieves waterproof effect by adding waterproofing agent inside the gypsum core and using special protective paper for waterproof boards; The evaporation of gas requires that the breathing space is usually too large, and there is a problem of uneven ventilation. In addition, in the production process, the slurry is stratified due to uneven addition of waterproofing agent, which will easily lead to foaming of the board, resulting in a decline in the qualified rate of the finished board. The production cost is higher, which makes the production process more simplified

Embodiment

[0019] see figure 1 , the present invention provides a waterproof paper-faced gypsum board processing method and processing device, and the processing flow will be described in detail in conjunction with the device below:

[0020] First, roll out the protective paper wound on the roll of the upper paper machine, and use the protective paper on the lower roller 11 below as the lower paper surface 10, and spread it flat on the forming table 31 of the platen machine, and the upper upper roller 11 above it The protective paper on the roller 12 is located above the lower paper surface 10 as the upper paper surface 20, and passes under the extrusion plate 32 of the plate press machine;

[0021] Before the protective paper enters the platen press, fill the gypsum board wet material on the paper surface 10 through the outlet of the mixer 2. There is no need to add gypsum waterproofing agent to the wet material of the gypsum board, but before the protective paper passes through the mix...

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.

Description

technical field [0001] The invention relates to a gypsum board preparation technology, in particular to a processing method and a processing device for a waterproof paper-faced gypsum board. Background technique [0002] The existing waterproof paper-faced gypsum board achieves waterproof effect by adding waterproofing agent inside the gypsum core and using special protective paper for waterproof boards; Air evaporation needs, usually the breathing space is too large, and there is a problem of uneven ventilation. In addition, in the production process, due to the uneven addition of waterproofing agent, the slurry is stratified, which will easily lead to foaming of the board, resulting in a decline in the qualified rate of the finished board. The higher production cost makes the production process more simplified. Contents of the invention [0003] The invention provides a waterproof paper-faced gypsum board processing method and a processing device, which are used to over...
