Abstract

The invention discloses a plasterboard starch adding control method and a system thereof. The method comprises the following steps: adding starch and clear water into a container, premixing the starch and the clear water, and outputting the premixed starch mixed solution fro the container; and mixing the starch mixed solution with clear water, injecting the obtained mixture to a mixer, and mixing the mixture wit a slip. The method and the system make the starch uniformly distributed in the slip, so the quality of plasterboards is improved, the use amount of the starch is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a solid material addition control technology, in particular to a starch addition control method and system for gypsum boards. Background technique [0002] In the gypsum board production process, in order to improve the bonding of the protective paper, the general method is to add starch appropriately. The amount of starch added in the molding process directly affects the bonding of the protective paper, and the bonding of the protective paper is good or bad. It also directly affects the key parameters such as the strength of the gypsum board. Therefore, the control of the amount of starch added and the way of adding has a crucial impact on the quality of the molding stage and the final gypsum board. At the same time, compared with other additives in gypsum board production, the amount of starch added is the largest. Therefore, in the case of strengthening the bonding of face paper, reducing the amount of starch added in gypsum...
