Problems solved by technology

Tourmaline can release negative oxygen ions, but tourmaline releases negative oxygen ions at a low rate and low concentration, which cannot meet the demand
[0004] However, there is no report related to desulfurized gypsum powder that can release negative oxygen ions.

Abstract

The invention relates to desulphurization gypsum powder capable of releasing negative oxygen ions and a preparation method thereof. The preparation method comprises the steps that 1, materials are taken: 50-80 parts of expanded vermiculite, 0.1-5 parts of tourmaline, 20-50 parts of desulphurization gypsum and 20-30 parts of other raw materials are weighed by volume as raw materials; 2, the raw materials are mixed: the raw materials are mixed through a stirrer and are stirred evenly to obtain the desulphurization gypsum powder capable of releasing the negative oxygen ions. Compared with the prior art, the desulphurization gypsum powder has the advantages of being capable of releasing the negative oxygen ions, environmentally friendly, good in practicability and the like.

Description

technical field [0001] The invention relates to a building material, in particular to a desulfurized gypsum powder capable of releasing negative oxygen ions and a preparation method thereof. Background technique [0002] Desulfurization gypsum is also known as exhaust gas desulfurization gypsum, sulfur gypsum or FGD gypsum. The main component is the same as natural gypsum, calcium sulfate dihydrate CaSO4.2H2O, with a content of ≥93%. Desulfurization gypsum is an industrial by-product gypsum obtained by coal or oil-burning industrial enterprises after treating sulfur dioxide in flue gas. The environmental pollution caused is also increasing. How to turn this bulk "waste" into an important mineral resource It is the subject of developing circular economy. The main component of desulfurization gypsum is calcium sulfate dihydrate crystals. The exterior wall decorative board is a new type of building exterior wall decoration and thermal insulation integrated material developed in...
