Gypsum Wallboard Chemical Additives
GEO SPECIALTY CHEMICALS, INC. PAGE 2 Wallboard Synopsis Gypsum wallboard consists of a hardened gypsum containing core surfaced with paper or other fibrous material suitable to receive a coating such as paint. It is common to manufacture gypsum wallboard by placing an aqueous core slurry comprised predominantly of calcined gypsum between(PDF) Retarding action of various chemicals on setting and,,Gypsum is used in the manufacture of variety of plasters mainly hemihydrate, anhydrite, light weight premixed compositions etc. for use in building, surgical, ceramic, dental and construction sectors. Industrially, the hemihydrate plasters (and forms) are generally used on a large scale for the interior decoration of buildings.Industrial Chemicals | Greenstar Fertilizers Limited,Gypsum works as an agent to remove saline or alkaline ingredients in the soil and acts more or less like manure. For industrial use. Gypsum is used to manufacture Gypsum boards. In the cement industry, gypsum is used to manufacturing lime. Gypsum is also used in manufacturing Plaster of Paris.Allied chemicals - Chemicals - Products - Tata Chemicals,,Gypsum. Gypsum, formed in crystalline lumps or powder form, is yet another product from the Tata Chemicals stable. Gypsum is used as an ingredient for Portland cement, for soil treatment, and to stabilise volatile compounds and dissolve nitrogenous ones. It also finds use as an inert filler in paints, paper, pharmaceuticals, insecticide dusts, etc.The Use of Lignosulfonates as Water Reducing Agents in,In 1998, close to one million tons of lignosulfonates were used worldwide in a variety of industrial applications. 1 The largest use of this material is as a dispersant of particle slurries such as concrete, clays, gypsum, and dyes. 2 In these applications, lignosulfonates must compete with synthetic dispersants such as condensation polymers of,PROCESS FOR THE MANUFACTURE OF GYPSUM BOARD,A process for the manufacture of a gypsum board wherein α-type hemihydrate gypsum by-produced in the wet process of phosphoric acid manufacturing is ground and mixed with water and a metal ion of iron or aluminum to form an aqueous slurry containing said gypsum and said slurry is enclosed between two sheets of board paper while maintaining the pH value of said slurry at 4 to 7, thereby said,
