Abstract
A process for producing inorganic molds involving molding a kneaded mixture containing a particulate inorganic material and water, which process comprises adding water-soluble hemicellulose to the kneaded mixture. The process provides inorganic molds with excellent dispersion stability of the inorganic material particles and improved plasticity, workability including fillability and shape retention, as well as strength.
Claims4
A process for producing an inorganic mold by molding of a kneaded mixture containing a particulate inorganic material and water, which process comprises extracting water-soluble hemicellulose from soybeans under acidic conditions at a pH near the isoelectric point of soybean protein, and adding said water-soluble hemicellulose to said kneaded mixture.
