Description
Technical Field
The invention relates to a method for preparing transparent glass, in particular to a melting-assisting clarifying agent for phosphogypsum glass, glass and a preparation method thereof.
Background
Phosphogypsum is industrial waste residue discharged in the wet-process production of phosphoric acid, and cannot be directly used due to the content of soluble phosphorus impurities. The phosphorus component in the phosphogypsum mainly has three forms of soluble phosphorus, eutectic phosphorus and precipitated phosphorus, and the soluble phosphorus has the greatest influence on the performance, so that the phosphorus component delays the setting and hardening of cement and building gypsum and reduces the strength of a hardened body. In large-scale phosphate fertilizer enterprises in China, wet-process slag discharge is mostly adopted, a dam is built in a valley, and a pipeline is built to collect and recycle reuse water; the small-sized phosphate fertilizer enterprises mostly adopt dry method for deslagging and flat land stockpiling. Because the yield of the phosphogypsum is huge, the market capacity of the comprehensively utilized product is limited, the phosphogypsum cannot be fully utilized in a short period and can only be stored in the open, and higher yard construction cost and operation and maintenance cost are brought to phosphorus chemical enterprises.
Transparent glass, which generally refers to transparent and colorless glass, is a very traditional and very common glass, and has very wide application in daily life and working environments.
In recent years of glass production and research, particularly in the production and research of glass production and processing enterprises near phosphogypsum stockpiling areas, in order to call corresponding policies and develop recycling of phosphogypsum waste residues, a plurality of glass production enterprises try to mix the phosphogypsum waste residues into glass, the mixing amount reaches more than 10 percent once, and a new thought is provided for recycling the phosphogypsum waste residues and solving the environmental problems caused by the phosphogypsum waste residues.
Although the phosphogypsum waste residue is used for producing the glass, the problems of environment and waste residue recycling are solved, the prepared glass has defects, and the main defects are that after the phosphogypsum is directly added into the glass raw material, more impurities are contained in the transparent glass, and the light transmittance is greatly reduced, so that the application of the transparent glass is greatly limited, the phosphogypsum cannot be widely accepted by the market, and the application of the phosphogypsum in the production of the transparent glass is limited in turn. In addition, after the phosphogypsum is used as a glass raw material, the calcining time is obviously increased, generally about 1100 ℃ for about 5 hours is required for calcining, the energy consumption is high, the glass production cost is high, and the application of the phosphogypsum in the production of transparent glass is also limited in turn.
Therefore, there is a need for development and improvement of the formulation and process for preparing transparent glass with phosphogypsum.
