INTEGRATED PRODUCTION UNIT OF GYPSUM POWDER, GYPSUM BOARD AND P.V.C. LAMINATED GYPSUM CEILING TILES
Calcium always occurs in the combined state. The most important naturally occurring compounds of calcium are calcium sulphate in mineral anhydrite and hydrated calcium sulphate in gypsum. Gypsum is employed in the manufacture of Plaster of Paris. Calcium sulphate occurs in enormous deposits of gypsum, CaSO4.2H2O. Large quantities of gypsum are employed in the manufacture of flooring plasters gypsum is used for making casts of statues and surgical treatment. For gypsum boards, the raw materials will be plaster of paris, special surface protection paper, glass fibre, frothing preparation and white latex. For the production of PVC laminated gypsum ceiling tiles, the capacity of the plant will be 1 million sq. mt./annum, PVC is one kind of plastics decoration materials. With PVC resin the principal ingredient mixed with moderate anti-age modifier and other materials, PVC is made through refining and calendaring. After coating, the gypsum board becomes light, insulated, warm, water-proof, fine-resistant and convenient to use. Gypsum board PVC coating, rich in specification, color and design, can be widely used in the decoration of interior walls and ceilings.
