Problems solved by technology

[0003] At present, most of the desulfurized gypsum comes from desulfurization of thermal power plants, and its quality fluctuates greatly, which has a great impact on the quality of gypsum board products, such as poor adhesion of paper surface and poor nail holding power; in addition, with the development of technology Progress, gypsum board companies at home and abroad have introduced lightweight gypsum boards, but as the surface density of gypsum boards decreases, most indicators such as board strength meet the requirements of relevant national standards, but the nail-holding force is often difficult to meet actual needs
Due to certain differences in building construction, it is inevitable that there will be unevenness during the decoration process. The existing solution for decoration construction is to level the multi-layer gypsum board or use putty to level it later, which will inevitably increase the amount of materials and cost.

Embodiment 1

[0044] to combine figure 1 As shown, the embodiment of the present invention provides a gypsum board, which includes a board body 1, and a mounting groove is opened on the board body 1, and the installation groove and the board body 1 are integrally formed; 1. It is fixed on the keel through the cooperation between the installation groove and the keel connector.

[0045] In the specific operation, the fitting connection between the gypsum board and the keel connector can be realized through the setting of the above-mentioned installation groove, and then the gypsum board can be firmly installed on the keel; the above-mentioned installation groove can be arranged on the board body according to the preset distance 1, the corresponding production can be completed in the molding stage; the installation groove and the plate body 1 can be set through the above-mentioned integral molding, which can effectively avoid the uncontrollability of the later on-site processing, and can effec...

Embodiment 2

[0054] Embodiment 2 of the present invention provides a gypsum board. The main structure is similar to that of Embodiment 1, and also includes a board body 1, and a mounting groove is also opened on the board body 1; for the specific setting of the main structure, please refer to the first embodiment For the record, the purpose here is to illustrate the difference between the two.

[0055] In this embodiment, the above-mentioned limiting structure is configured as a limiting protrusion 23; the limiting protrusion 23 is arranged on the outer side wall of the embedded block 2, and / or is arranged on the inner side wall of the cylindrical groove.

[0056] to combine figure 2 As shown, in the specific operation, the above-mentioned limiting protrusion 23 is arranged on the outer side wall of the embedded block 2, and the setting of the above-mentioned limiting protrusion 23 can also effectively improve the adhesion between the embedded block 2 and the installation groove, thereby ...

Embodiment 3

[0060] Embodiment 3 of the present invention provides a gypsum board. The main structure is similar to that of Embodiment 1. It also includes a board body, and an installation groove is also opened on the board body. For the specific configuration of the main structure, please refer to the description in Embodiment 1. The purpose here is to illustrate the difference between the two.

[0061] In this embodiment, adhesive glue is filled between the embedding block and the cylindrical groove.

[0062] In the specific operation, the amount of adhesive glue can be filled between the embedded block and the cylindrical groove, which can also effectively avoid the internal stress concentration of the plate body caused by the limit protrusion or the sharp angle of the external thread structure, and can effectively improve The internal structural stability of the board body can effectively improve the overall structural stability of the gypsum board.

Abstract

The invention discloses a preparation method of gypsum boards. The preparation method comprises the following steps of step a, preparing gypsum feed pulp; step b, placing embedded blocks into the gypsum feed pulp according to a pre-set spacing; and step c, performing drying and shaping operation on the gypsum feed pulp and the embedded blocks. The application can be applied to the technical fieldof sheet materials. Through the adoption of the preparation method disclosed by the invention, the defects existing in the prior art can be effectively overcome, the connecting pieces of the gypsum boards can be arranged in an embedding manner, and the structural stability of later connection can be effectively improved.

Description

technical field [0001] The present application relates to but not limited to the technical field of boards, especially a method for preparing gypsum boards. Background technique [0002] Paper-faced gypsum board is one of the three most widely used decorative boards in my country. It has the characteristics of light weight, sound insulation, heat insulation, strong processing performance, and simple construction methods. In the prior art, using desulfurized gypsum as raw material to manufacture paper-faced gypsum board is an effective way to efficiently absorb desulfurized gypsum. It not only solves the problem of environmental pollution caused by bulk solid waste in thermal power plants, but also provides cheap raw materials for gypsum board factories. [0003] At present, most of the desulfurized gypsum comes from desulfurization of thermal power plants, and its quality fluctuates greatly, which has a great impact on the quality of gypsum board products, such as poor adhes...
