Title: Gypsum structure for casting
Inventor: OSADA KANJI
IPC: B22C1/08
Filed: 1988-07-26
Abstract: PURPOSE:To shorten the time for drying and dehydrating and to obtain the gypsum structure for casting having excellent air permeability, heat resistance, etc., by adding inorg. fibers such as glass fibers, ceramics fibers and carbon fibers forming a network structure to the structure. CONSTITUTION:The inorg. fibers, for example, powdery microglass fibers, ceramics fibers such as alumina silicon carbide, carbon fibers and ground asbestos are mixed alone or properly with the gypsum for casting and the mixture is kneaded and is cured in a mold. The inorg. fibers entangle like nets in the gypsum to form the unshaped network structure, by which the capillary tubes of the continuous fibers are formed. The moisture in the gypsum mold can flow along the continuous inorg. fibers by capillarity. The free water and water of crystallization in the inside are well expelled to the outside by the capillarity at the time of drying and dehydrating the gypsum mold after parting. The drying and dehydrating stages are thus executed in a short period of time.
