How many kinds of gypsum board
Gypsum board with ordinary paper gypsum board, water-resistant plaster board and fire-resistant plaster board three. Ordinary paper gypsum board for indoor walls and ceiling; water-resistant plaster board for the kitchen, bathroom walls and ceiling; refractory plaster board for refractory requirements of high indoor partitions and ceiling. Ordinary paper gypsum board is based on building gypsum as the main raw material, mixed with fiber and admixture constitute the core material, and with the face paper firmly together. The edge of the ordinary gypsum board is rectangular, 45. Chamfer, wedge, semicircular and round. Length of 1800,2100,2400,2700,3000,3300,3600mm, the width of 900,1200 mm; thickness of 9,12,15,18 mm. Products are special goods, first-class goods and three qualified products. Water-resistant plaster board is based on building gypsum as the main raw material, mixed with the amount of water-resistant admixture constitute water-resistant core material, and with water-resistant protective paper firmly bonded together. Water-resistant gypsum board edge shape is divided into rectangular, 450 chamfer, wedge, semi-circular and round five, the length of 1800,2100,2400,2700,3000,3300,3600mm; width 900, lZDOmm; Thickness of 9,] 2,15mm. Products are special goods, first-class goods and three qualified products. Refractory paper gypsum board is based on building gypsum as the main raw material, mixed with eight appropriate inorganic refractory fiber reinforced materials constitute refractory core material, and with the face paper firmly stick together. It has the ability to keep it from breaking when burning under high temperature open flame. The edges of the refractory gypsum board are rectangular, 45 0 chamfered, wedge, semi-circular and rounded. Length of 1800,2100,2400,2700,3000,3300,3600mm; width of 900,1200mm; thickness of 9,12,1 5,18,21,25 mm. Products are special goods, first-class goods and qualified products.
