With the joint venture of USG Boral and Siam Cement Group (SCG), Elephant Gypsum Board is enabling builders and contractors alike to build faster and build better for a greater tomorrow.
A gypsum block is made of gypsum plaster and water. The manufacturing process [1] is automated at production plants where raw gypsum (CaSO 4 #183;2H 2 O) is ground and dried, then heated to remove threequarters of the bound water and thus transformed into calcium sulfate hemihydrate (CaSO 4 #183;#189;H 2 O), also known as gypsum plaster, stucco, calcined gypsum or plaster of Paris.
ING AGENTS FOR GYPSUM BOARD MANUFACTURE ABSTRACT This invention relates to a novel means of manufacture of gypsum board. The improvement herein comprises the use of sodium and/or ammonium salts of ethoxylated, sulfated alcohols as ing agents, said alcohols being a mixture of primary, linear alcohols having an average chain length of 9 carbon atoms.
Calcined gypsum is mixed with water to make a slurry (muddy state). Then, the slurry is poured into a line (belt) where board liners are flowing down, thus sandwiched with board liners. 3. Drying process. Boards are sent to a drying machine (dryer) to remove excess water content.
with gypsum and water in various proportions to fabricate gypsumwood and gypsumrubber cylindrical samples and standard solid br icks with six holes using appropriate molds.
Gypsum board is made mainly of paper (generally called as liner) and gypsum. When you convert quot;calcined gypsumquot; and water into quot;gypsum dihidratequot;, needleshaped crystals are formed and the gypsum solidifies. The bonding of paper and gypsum uses the mechanism that this needlelike crystal digests into the fiber of the paper and integrates it.
A gypsum board is a boardshaped one in which a core based on dihydrate gypsum is covered with a base paper for gypsum board, wherein, as for manufacturing thereof, a calcined gypsum, a bonding aid, a hardening accelerator, for lightening thereof, another additive, and the like, and further an admixture and water are kneaded, and thus obtained calcined gypsum slurry is poured into between

fluegas gypsum. The gypsum boards consisted out of 9 wt% water, which was removed before the calcination step. After the calcination, the stucco was rehydrated and the slurry was put between paper to make the final gypsum boards, which had to be dried for the last time. All the heating was provided by a
ASTM standards govern the manufacture of gypsum board and set strict criteria for strength, water resistance, and other characteristics. To produce gypsum board, crushed natural gypsum or synthetic gypsum is heated or calcined to dehydrate the feedstock. Next the calcined gypsum is mixed with water and additives to form a slurry which is fed
