Abstract

Способ изготовления альфа-полугидрата сульфата кальция из дегидрата сульфата кальция, включает такие стадии: а) заполнения оборудованного смесителем автоклава (1) дегидратом кальция, b) непрямой подогрев оборудованоного смесителем автоклава (1), c) управляемое добавление и примешивание воды, d) предотвращение налипанию материала на поверхности реакционной камеры с помощью движимых цепей (3), расположенных на лопатях и/или приводном валу (16) оборудованного смесителем автоклава (1), e) периодическое или беспрерывное регулирование давления в реакционной камере путем выпуска пара по достижению определенного давления внутри камеры, причем пар выводят через циклонный сепаратор (17) и регулируемый клапан (18), f) подведение холодного воздуха для остаточного высушивания, g) удаление технологического материа�
