Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0024] The application provides a kind of preparation method of gypsum board, such as figure 1 Shown, preparation method comprises the following steps:

[0025] (1) Score the left and right sides of the lower protective paper;

[0026] (2) Apply adhesive in the scored area on the left and right sides of the lower face paper;

[0027] (3) Fold the left and right sides of the lower protective paper through the mold, so that the lower protective paper forms a tank body that can accommodate the gypsum slurry;

[0028] (4) Place fillers in the scored areas on the left and right sides of the l...

Abstract

The application provides a method for preparing gypsum board. The preparation method includes the following steps: (1) scoring the left and right sides of the lower protective paper; (3) Fold the left and right sides of the lower protective paper through the mold, so that the lower protective paper forms a tank body that can accommodate the gypsum slurry; (4) place fillers in the scored areas on the left and right sides of the lower protective paper (5) spray gypsum slurry in the tank formed by the lower protective paper; (6) bond and fix the upper protective paper and the lower protective paper to form a gypsum board wet board; (7) gypsum board The wet board is solidified, cut, dried, and sawn to make a finished gypsum board. The preparation method of the gypsum board provided in the present application can produce a gypsum board with irregular board edges, which can be applied to various splicing situations.

Description

technical field [0001] The present application relates to but not limited to the field of gypsum board, especially a preparation method of gypsum board. Background technique [0002] The traditional gypsum board keel wall structure is a relatively old building structure wall. The specific construction method is to use the horizontal keel as the sky and earth keel, use expansion bolts to fix the roof and the ground respectively, and use the vertical keel to connect the sky and the earth. The junction of the horizontal keel and the vertical keel is connected with self-tapping nails, plaster boards are pasted on both sides of the keel, and rock wool boards are installed between the gypsum boards. Therefore, the traditional gypsum board keel wall is basically pure manual work, which is inefficient and produces a large amount of construction waste, resulting in a poor construction environment and destroying the surrounding environment. At the same time, the construction quality c...
