Problems solved by technology

Most of the existing yellow phosphorus electric furnaces use molten slag to flow out intermittently. After the ferrophosphorus is settled, the molten slag at 1200-1450°C flows into the water quenching pool for water quenching to obtain water quenching slag. Steam, causing serious environmental pollution and visual pollution

specific Embodiment

[0026] see figure 1 Shown, the specific embodiment that the present invention provides is as follows:

[0027] The method of using yellow phosphorus slag to prepare light-duty composite artificial stone profiles in this embodiment, the method includes:

[0028] S1. Preparation of air-porous base layer: mix silica powder and limestone granules and evenly arrange them on the bottom of the base-layer forming mold, then pour yellow phosphorus slag into the base-layer forming mold, and make the air-hole base layer profile after heat preservation, cooling and cutting processes ; Among them, the base forming mold is made of materials resistant to 1600 ° C or above, such as mullite shed board;

[0029]S2. Preparation of surface layer and molding of light-duty composite artificial stone profiles, mixing and stirring the adhesive with natural stone granules or powders, and inorganic mineral pigments to obtain a mixture, and putting the pore-based base profile into the bottom of the art...

Abstract

The method for preparing light-duty composite artificial stone profiles using yellow phosphorus slag provided by the present invention includes: S1. Preparation of pore base, mixing silica powder and limestone granules evenly on the bottom of the base forming mold, and then adding yellow The phosphorus slag is poured into the base forming mold, and after heat preservation, cooling, and cutting processes, the pore base profile is obtained; S2. Surface layer preparation and light composite artificial stone profile molding, the adhesive is combined with natural stone pellets or powder, Inorganic mineral pigments are mixed and stirred to obtain the mixture, and the pore base profile is put into the bottom of the artificial stone forming mold, and then the mixture is injected into the artificial stone forming mold and evenly covered on the surface of the pore base profile through the compounding process to form a surface layer; Lightweight composite artificial stone profiles are produced through molding and polishing processes. The beneficial effect of the present invention is reflected in that it not only reduces the specific gravity of the pore-based profile, but also reduces the residual free calcium oxide and magnesium oxide content in the yellow phosphorus slag, so that the yellow phosphorus slag can be turned from waste to treasure.

Description

technical field [0001] The invention relates to the technical fields of metallurgy, chemical industry and building materials, in particular to a method for preparing light composite artificial stone profiles by using yellow phosphorus slag. Background technique [0002] Artificial stone is made of high molecular polymer or cement or a mixture of the two as a binder, with natural stone fragments and / or natural quartz stone or aluminum hydroxide powder as the main raw material, adding pigments and other auxiliary agents, and mixing and stirring , Condensation and curing processes such as composite material. It mainly includes artificial stone solid fabrics, artificial stone quartz stone and artificial stone granite and other products. According to the composition of the binder, it can be divided into three categories: organic, inorganic and organic-inorganic composite artificial stone. [0003] Organic artificial stone is made of crushed stone, stone powder, etc. as the basi...
