Desulfurization gypsum powder furniture board

Abstract

The invention discloses a desulfurization gypsum powder furniture board. A raw material formula is as follows: 80-90 parts of desulfurization gypsum powder, 8-12 parts of polyvinyl chloride and 4-6 parts of polyethylene (PE) wax in a proportion of the raw material formula. A preparation method comprises the following steps of: (1) weighing 80-90 parts of desulfurization gypsum powder, 8-12 parts of polyvinyl chloride and 4-6 parts of PE wax in a proportion of the raw material formula; (2) fully mixing and stirring the weighed materials in a sealed warming stirrer for 10 minutes every time, wherein the stirring quantity every time is 300 liters; (3) transferring a mixed material to a blank body mould to perform extrusion molding; (4) sanding and grinding; (5) performing surface treatment and spraying with ultraviolet (UV) paint; (6) splicing; and (7) packaging a finished product and storing into a warehouse. By using the desulfurization gypsum powder furniture board, resource recycling of the desulfurization gypsum powder is realized, and wastes are turned into treasures, so that environment pollution is reduced; and meanwhile, the furniture board has the advantages of hard texture, acid-alkali resistance, anti-aging, and environment protection, and the water absorption and the radioactive poisoning are avoided, and the pollution is prevented; and therefore, the desulfurization gypsum powder furniture board can be safely used.

Description

technical field [0001] The invention relates to the field of building boards, in particular to a desulfurized gypsum powder furniture board. Background technique [0002] Coal-fired power generation is the largest emitter of sulfur dioxide, so our government attaches great importance to it. Thermal power plants consume more than 50% of the country's coal while converting chemical energy into electrical energy. Coal ash, desulfurized gypsum and other solid emissions, as the national environmental protection requirements for desulfurization of power plants are getting higher and higher, the output of desulfurized gypsum is increasing, and the environmental pollution caused is also increasing. How to dispose of this large amount of "waste It is the subject of the development of circular economy to turn "things" into important mineral resources. The main component of desulfurization gypsum is calcium sulfate dihydrate crystals. All kinds of wooden furniture currently on the mar...
