Application of Desulfurization Gypsum Powder
1. In the production line of desulfurization gypsum powder, most of desulfurization gypsum is used as cement retarder in the production process of desulfurization gypsum, followed by the production and manufacture of many contemporary necessary building decoration materials such as engineering gypsum. For example: concrete auxiliary materials, plastering gypsum, gypsum block bricks, making fertilizers, improving the alkalinity of soil environment, making foundation filling materials, fireproof materials, etc. Due to the variability of desulfurization gypsum itself and the strict standards of facilities and processing technology, the cost of concrete products is high. In order to better control the cost, coal enterprises generally choose pure natural gypsum.
2. In addition, the fatal defects such as low compressive strength and poor waterproof of desulfurization gypsum limit its wide application. In terms of utilization rate, desulfurization gypsum is far less than overseas. Therefore, it is an important problem for people to expand the application scope of desulfurization gypsum and improve its performance index.
3. Nowadays, gypsum hemihydrate is a commonly used additive in building materials, also known as engineering building gypsum. The main component of gypsum hemihydrate is calcium bicarbonate hemihydrate (CaSO4? 1/2H2O)[9], but the main component of desulfurization gypsum is hydrochloric acid dihydrate (CaSO4? 2H2O), it is necessary to take some measures to convert gypsum dihydrate into gypsum hemihydrate. First of all, the desulfurization gypsum must be thoroughly dried to ensure that the deviation of heat treatment method is avoided as much as possible, and then the heat treatment process can be carried out. It is necessary to choose a suitable heat treatment method and then crush the obtained hemihydrate gypsum.
4. The transformation of desulfurized gypsum into semi-hydrated gypsum also conforms to the regulation of coordinated development of _ source, which further improves the utilization rate of sediment and provides social value and ecological benefits for production, daily life and social development.
