Abstract
A kind of Desulfurization gypsum sand pulp, belongs to material of construction.This Desulfurization gypsum sand pulp comprises surface layer and whitewashes desulfurated plaster and bottom layer brushing desulfurated plaster two kinds, described surface layer whitewashes desulfurated plaster and comprises: desulfurated plaster, SC calcium sulphate retarder, flyash and ether of cellulose, desulfurated plaster is 79.6%, SC calcium sulphate retarder is 0.35%, flyash is 20%, ether of cellulose is 0.010%, is all weight percentage; Described bottom layer brushing desulfurated plaster comprises: desulfurated plaster is 79.6%, SC calcium sulphate retarder is 0.35%, flyash is 20%, ether of cellulose is 0.010% and river sand, be 1:2 according to desulfurated plaster, SC calcium sulphate retarder, flyash and cellulose ether mixture and the ratio of sand, be weight percentage.Advantage: this Desulfurization gypsum sand pulp forms primarily of industrial residue, is applicable to the facing of unselected clay brick wall, Aerated Concrete wall etc. under dry environment and plasters, in plant produced, can realize convenient, fast construction.Improve serviceability and physical and mechanical property, "dead", unharmful substance and non-corrosiveness.
Description
Technical field
The present invention relates to a kind of material of construction, particularly a kind of Desulfurization gypsum sand pulp.
Background technology
The flue gas desulfurization that current industry uses produces a large amount of industrial residue-desulfurated plaster, stack these industrial residue-desulfurated plasters and occupy a large amount of soils, good farmland, also there is no a kind of well treating method, bringing secondary pollution to our life, is also our pollution problem to environment urgently to be resolved hurrily.
Summary of the invention
Technical problem: the object of the invention is to provide a kind of Desulfurization gypsum sand pulp, utilize industrial by-products, solves industrial residue to the pollution problem of environment.
Technical scheme: the object of the present invention is achieved like this: this Desulfurization gypsum sand pulp comprises surface layer and whitewashes desulfurated plaster and bottom layer brushing desulfurated plaster two kinds, described surface layer whitewashes desulfurated plaster and comprises: desulfurated plaster, SC calcium sulphate retarder, flyash and ether of cellulose, desulfurated plaster is 79.6%, SC calcium sulphate retarder is 0.35%, flyash is 20%, ether of cellulose is 0.010%, is all weight percentage; Described bottom layer brushing desulfurated plaster comprises: desulfurated plaster is 79.6%, SC calcium sulphate retarder is 0.35%, flyash is 20%, ether of cellulose is 0.010% and river sand, be 1:2 according to desulfurated plaster, SC calcium sulphate retarder, flyash and cellulose ether mixture and the ratio of sand, be weight percentage.
The standard diffusion degree water consumption that described surface layer whitewashes desulfurated plaster is 35%, and the standard diffusion degree water consumption of bottom layer brushing desulfurated plaster is 60%; Described flyash is II grade, and ether of cellulose is hydroxypropyl methyl cellulose ether, and viscosity is 100000mPas.
Beneficial effect, owing to have employed such scheme, desulfurated plaster is utilized to prepare Desulfurization gypsum sand pulp for main raw material(s), for the Desulfurization gypsum sand pulp that the facing such as unselected clay brick wall, Aerated Concrete wall under dry environment is plastered, solve desulfurated plaster based on stocking and storing, land occupation resource, to the problem of environmental danger, effectively control the environmental pollution of China, for the modern urban construction of China provides a kind of novel starting material.Improve serviceability and the mechanical property of Desulfurization gypsum sand pulp, while meeting national regulation, improve the performance of Desulfurization gypsum sand pulp largely.Described performance index all meet specification.Selected material has desulfurated plaster and the flyash of larger component, solves the problem of industrial residue environmental pollution.
Advantage: this Desulfurization gypsum sand pulp forms primarily of industrial residue, is applicable to the facing of unselected clay brick wall, Aerated Concrete wall etc. under dry environment and plasters, in plant produced, can realize convenient, fast construction.Desulfurization gypsum sand pulp prepared by the present invention significantly improves its serviceability and physical and mechanical property, "dead", unharmful substance and non-corrosiveness.The target that environmental protect saves the material of construction of the energy and innovation China can be realized, produce good Social benefit and economic benefit.
