Heilongjiang gypsum powder
1, the original physical state and characteristics are different。While other gypsum is bonded together in lumps, desulfurized gypsum exists as individual crystalline particles。From the point of view of characteristics, the easy grinding difference between desulphurized gypsum and gypsum is large, the coarse particles of other gypsum after grinding are mostly impurities, and the desulphurized gypsum has more particles than gypsum, and the fine particles are impurities, and its characteristics are the opposite of natural gypsum。
2. Particle size and grading are different。The particle size of desulfurized gypsum is relatively average, its distribution zone is very narrow, high fineness (more than 200 mesh), and the particles are mainly concentrated between 30-60μm, and the grading is far worse than that of other gypsum powder after grinding。
3. Different yields。The output of desulfurized gypsum is evenly distributed throughout the country，In particular, the production of desulfurized gypsum is also very large in the developed eastern region where a large number of gypsum products are consumed，And the quality of desulfurized gypsum is very high，Generally more than 90%;In this way, it makes up for the major defects of small reserves, low output and far away from consumption of other high-quality gypsum in China。
Heilongjiang gypsum powderIt is a monoclinic crystalline mineral, a hydrate whose main chemical composition is calcium sulfate (CaSO4)。Gypsum is a widely used industrial and building material。Can be used in cement retarder, gypsum building products, model making, food additives, sulfuric acid production, paper filler, paint filler and so on。
