Application

1. China stipulates that it is used as a flour treatment agent (as a diluent of benzoyl peroxide), with a maximum usage of 1.5g/kg; As a coagulant, it can be used in soybean products and canned foods according to production needs

2. Can be used for building materials, heat insulation materials, coatings, reinforcement materials, etc. Used in the paper industry, it can replace part or most of the pulp. The length-diameter ratio ≤50 can be used as a high-level filler for paper, which can greatly increase the output of paper, reduce wood consumption, help protect the environment and reduce waste water pollution. In the chemical industry can be used as reinforcement materials, anhydrous sulfuric acid whisker can be used in plastic granulation to enhance the strength of plastic particles, high temperature resistance, and reduce costs. In the production of polyvinyl chloride, polyethylene, propylene, polystyrene and other plastics can enhance the performance of all aspects of the product, improve the fineness, dimensional stability, surface finish, tensile strength, bending strength, bending elasticity and thermal deformation temperature, and reduce the wear of equipment. Calcium sulfate whisker has good friction, thermal insulation, heat insulation, fire protection, non-conductor insulation and other properties, can replace asbestos as friction material, thermal insulation material and fire (flame retardant) material. The softening point of asphalt can be significantly improved as asphalt filler.

3. As an early strength agent in concrete admixtures, the general content is about 3%, which is used to adjust the setting time and mixed in cement. When calcium sulfate is added into concrete, it has obvious early strength effect. Used as a filler in the coatings and paper industry. Used as fertilizer in agriculture, it can reduce soil alkalinity and improve soil properties. Food grade products can be used as nutrition supplement, coagulant, yeast food, dough conditioner and chelating agent, can also be used as tomato, potato canned tissue strengthening agent, brewing water hardener, wine flavor enhancer.
