Embodiment Construction

[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0063] During concrete implementation: a kind of plastering gypsum, it is characterized in that, adopts following raw material: major ingredient is hemihydrate gypsum powder; Auxiliary material comprises retarder, methyl cellulose, industrial flour, wood cellulose, pearl powder and quartz sand, Obtained by stirring and mixing.

[0064] In this way, using the hemihydrate gypsum powder as the raw material, the industrial by-product gypsum can be used to reuse the waste, which is greatly beneficial to environmental protection and reduces the production cost of the product. Combined with various auxiliary materials to mix evenly, various materials cooperate with each other to ensure the product quality of plastering gypsum.

[0065] Specifically, the mass ratio of various materials is 10-30% of quartz sand, 3-15% of pearl powder (closed), 0.05-0.1% of retarder, ...

Abstract

The invention discloses a gypsum plaster. The gypsum plaster is obtained by stirring and mixing a hemihydrate gypsum powder, a retarder, methyl cellulose, industrial flour, wood cellulose, pearl powder and quartz sands until uniformity. The invention also discloses a gypsum plaster preparation system for preparing the gypsum plaster. The gypsum plaster prepared in the invention has the advantagesof good quality, and realization of no mildewing, efflorescence or greening in the use process, and well meets the use requirements of the gypsum plaster.

Description

technical field [0001] The invention belongs to the technical field of plastering gypsum, and in particular relates to a plastering gypsum and a preparation system thereof. Background technique [0002] Gypsum, whose main component is calcium sulfate, includes natural gypsum and industrial gypsum. Among them, industrial gypsum, also known as industrial by-product gypsum, is a by-product of some industrial production processes, mainly including phosphogypsum and desulfurization gypsum, of which phosphogypsum accounts for more than half of industrial by-product gypsum. At present, the cumulative stockpiles of industrial by-product gypsum in my country have exceeded 300 million tons, of which phosphogypsum has reached more than 200 million tons. A large amount of industrial by-product gypsum is piled up, which not only occupies land, but also wastes resources. The acid and other harmful substances contained in it are likely to pollute the surrounding environment, which has bec...
