The invention relates to the field of gypsum board production, and provides a gypsum board production system, which can quickly match the admixtures for solidifying soluble impurity ions according to the types and contents of impurity ions in raw materials, so as to achieve the purpose of removing soluble impurity ions in raw materials, reduce The influence of soluble impurity ions on the quality and production process of gypsum board was studied, and the gypsum board was further optimized.

Description

technical field [0001] The present invention relates to the field of gypsum board production, more specifically, to a gypsum board production system. Background technique [0002] The resource utilization of industrial by-product gypsum can not only reduce the mining of gypsum mines, but also solve the problem of raw materials for gypsum products in areas without natural resources, and also reduce the pollution of solid waste to the environment. However, at present, domestic desulfurized gypsum contains many soluble impurity ions, and these soluble impurity ions have great harm to the quality of gypsum boards, especially the bonding performance between the board core and the protective paper and the performance when it is damp. In addition, its It also has a greater impact on processes such as calcination and hydration. [0003] At present, the high-speed production of gypsum board requires many and complex raw materials.

Problems solved by technology

However, at present, domestic desulfurized gypsum contains many soluble impurity ions, and these soluble impurity ions have great harm to the quality of gypsum boards, especially the bonding performance between the board core and the protective paper and the performance when it is damp. In addition, its It also has a greater impact on processes such as calcination and hydration

[0003] At present, the high-speed production of gypsum board requires many and complex raw materials. Different power plants have different raw materials. Even in the same power plant, the impurity content in raw materials at different times is also very different. The chemical detection method for impurities in gypsum raw materials requires a large workload. The quantity is limited and cannot be dynamically matched with the production situation

Therefore, when adding admixtures to low-quality desulfurized gypsum to solidify or adsorb impurity ions, there will be a phenomenon that the amount of admixtures does not match the raw materials, and high-speed, stable, and continuous production cannot be achieved.
