Abstract

PURPOSE: To obtain a desiccating agent which maintains hygroscopic effect for a long time by immersing lump-shaped gypsum into an aqueous calcium chloride soln., or stirring gypsum powder into the aqueous calcium chloride soln. to the form of lumps, then heating the same at specific temp.
CONSTITUTION: Lump-shaped gypsum is immersed in an aqueous calcium chloride soln. or gypsum powder is added to the aqueous calcium chloride soln. and the mixture is stirred to form coagulated lumps, after which it is heated and dried at about 200°C, whereby a granular desiccating agent is produced. Since the resulted desiccating agent has gentle hygroscopicity, it is usable for a long period of time, and this makes an important contribution to the protection and safety of the merchandise to be dried; moreover raw materials are ample and production is feasible at low costs.
