Problems solved by technology

[0004] However, when coating the surface of the facial paper, since the facial paper is always in a moving state, there are certain wrinkles and local bulges on the surface of the facial paper. When coating, the local coating is uneven, resulting in low coating quality

Embodiment 1

[0041] see figure 1 , in the figure a represents the working plane, b represents the coating roller, and c represents the surface paper, a multi-directional balanced gypsum board coating process, including the following steps:

[0042] S1. Install a slurry pump and a coating machine on the mixer. The slurry pump extracts the slurry from the mixer, and transfers the slurry along the conveying pipe to the front of the coating machine through the slurry transfer pump;

[0043] S2, see figure 2 , in front of the outlet of the conveying pipe, traverse the stroking plate 1, and make the tissue paper guided by the traction mechanism pass through the traversing stroking plate 1, such as Figure 4, control the horizontal change of the smoothing plate 1 to extend horizontally along the face paper first, so that the smoothing strip 3 and the surface of the face paper are attached to each other, and then control the contact length of the smoothing strip 3 and the paper surface to change...

Abstract

The invention discloses a multidirectional balanced paper surface gypsum board coating process, and belongs to the field of paper surface gypsum board production. Two transverse flattening plates are arranged in an area before coating, so that an isosceles triangle-shaped flattening structure is formed on the surface of a paper surface; the contact part of the transverse flattening plate far away from the coating roller and the surface of the surface paper is controlled to be fixed, the contact area of the flattening strip on the other transverse flattening plate and the transverse flattening plate is controlled to be increased and then decreased, the process is continuously repeated, and in the process, the bottom edge of an isosceles triangle formed by the contact part of the flattening strip and the surface of the paper is continuously changed; by means of the guiding device, paper surface wrinkles or local protrusions are guided to the two sides and gradually move to the edge to disappear, balance and stability of the surface paper during operation are effectively guaranteed, and compared with the prior art, the conditions of wrinkles and local protrusions of the surface paper before coating are greatly reduced, and the uniformity of the coating is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of gypsum board production, in particular to a multi-directional balanced gypsum board coating process. Background technique [0002] The gypsum board is made of building gypsum as the main raw material, mixed with appropriate amount of additives and fibers as the core, and made of special cardboard as the protective surface. Paper-faced gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method. Gypsum board can be divided into four categories: ordinary, water-resistant, fire-resistant and moisture-resistant. [0003] In the production control standard of gypsum board, the physical property data of the board is particularly important. With the continuous innovation of the production process and the improvement of the speed, the board is easy to be over-burned or under-temperature during the board control process, resulting in ...
