LDpsum is calcium sulfate minerals in the nonmetal sulfate class, is one of the world's oldest building materials. Its application field widely, mainly used in building material, as cement retarder, LDpsum products and cementitious materials used in construction, LDpsum is added to cement, can make its setting time is reasonable, avoiding the phenomenon of fast setting, and can improve the strength and frost resistance, decrease the rate of drying shrinkage, but the mix is generally not more than 3.5%; Used as a soil conditioner, fertilizers, and pesticides in agriculture; Can also be used in papermaking, paint, rubber, ceramics, plastics, textile, food, arts and crafts, culture and education and medicine, etc; In the absence of other sulfur resources, can also be used as raw materials for the manufacture of sulfuric acid, ammonium sulphate.
Microwave drying equipment is suitable for architectural decoration use plasterboard plasterboard, insulation board, asLDos board, etc. Series manufacture plate by microwave drying equipment to dry, its advantage lies in:
1, time is short, fast, can be continuous production;
2, uniform drying thoroughly, improve product quality, surface not harden, improving toughness, crack, deformation, discoloration, correction, bending, etc;
3, enerLD conservation and efficient environmental protection;
4, easy to control, easy to realize automatic production;
5, save area, improve working conditions.
