Problems solved by technology

For example, phosphogypsum is added as raw material to make pigments; phosphogypsum is added as raw material to make paint; phosphogypsum is added to make insulation blocks, insulation bricks and other technologies; although these apply phosphogypsum to building materials The field has been generalized and mass-produced, but the annual discharge of phosphogypsum is still difficult to solve, so that a large amount of phosphogypsum is still stockpiled. Therefore, the re-application of phosphogypsum needs to continue to expand the field and expand the scope of phosphogypsum. The amount of application, thereby alleviating the defects caused by the stockpiling of phosphogypsum

Abstract

The invention relates to the technical field of chemical building materials and particularly relates to a jade-imitated decorative plate made of a phosphogypsum base material and a preparation method of the jade-imitated decorative plate. Phosphogypsum, quick lime, coal ash, ceramic fibers and a jade-imitated coating are reasonably proportioned and combined, and raw materials provided in the preparation method are treated, aged, ground and stirred, so that complex biochemical reaction is carried out among all the raw materials; in addition, parameters in all the process steps are controlled so that oriented biochemical reaction is carried out among all the raw materials, soluble impurities in phosphogypsum are reduced, the solidification characteristic of a phosphogypsum product is promoted, and the strength and freezing-thawing resistance of the phosphogypsum base material are improved; the coal ash and the ceramic fibers are added so that the performance of the phosphogypsum base material is improved; in addition, the combination and proportion of the raw materials are controlled, and steps in the preparation method and technical parameters in the steps are combined, so that the radioactivity, heat insulation property, freezing-thawing resistance and breaking strength of the phosphogypsum base material are improved.

Description

technical field [0001] The invention relates to the technical field of chemical building materials, in particular to a phosphogypsum base material imitation jade decorative board and a preparation method thereof. Background technique [0002] Phosphogypsum is a large amount of waste produced in wet-process phosphoric acid, and according to the increase in the output of my country's wet-process phosphoric acid production process and the gradual expansion and growth of the phosphate fertilizer industry, the stockpiling of phosphogypsum has also increased dramatically. Due to its own performance, phosphogypsum is stored and placed in the natural environment. If it is not properly treated, it will bring serious pollution to the environment; at the same time, a large amount of available resources contained in phosphogypsum will also be wasted. into the natural environment, and then bring serious economic burdens to enterprises such as phosphate fertilizer and phosphoric acid. ...
