Abstract: PURPOSE:To provide a production of a cement dispersant. CONSTITUTION:This cement dispersant is produced by the following processes (1) and (2) in the production of the alkali metal salt of a naphthalenesulfonic acid-formalin condensate. (1) One mol of naphthalene is sulfonated with 1.12-1.17 mols of fuming sulfuric acid (expressed in terms of sulfuric acid). (2) Neutralization is carried out with the double salt consisting of one mol of sodium salt and 0.8-1.2 mols of potassium salt. As a result, the process for producing the dispersant is drastically simplified, and the cost is reduced. The dispersant has excellent dispersibility and is widely used in the field of ready-mixed cement, secondary products, etc.

Abstract: PROBLEM TO BE SOLVED: To provide an opening method capable of improving the dispersibility of inorganic fibers by suppressing the re-aggregating of the inorganic fibers, and to provide a composite board having improved bending strength.
SOLUTION: In this opening method, the inorganic fibers are opened in water added with a quaternary ammonium salt type cationic surfactant. The inorganic fibers show negative potential and the cationic surfactant shows positive potential in water. Then the adsorption of the cationic surfactant to th surface of the inorganic fiber is considered to be strong. As a result, the inorganic fibers, on which the cationic surfactant is adsorbed, repel each other by the positive charge of the cationic surfactant adsorbed on the surface to improve the dispersibility to suppress the re-aggregation.
