Description
(54) СПОСОБ СТАБИЛИЗАЦИИ ПОЛУГИДРАТА СУЛЬФАТА КАЛЫШЯ
Claims (2)
- Формула изобретения1. Способ стабилизации полугидрата сульфата кальция в производстве экстракционной фосфорной кислоты путем добавления водных растворов полифосфатов щелочных металлов в качестве стабилизатора, отличающийся тем, что, с целью снижения адгезионных свойств целевого продукта и исключения потерь стабилизатора, в качестве последнего используют гексаметафосфат, представляющий собой смесь линейных и разветвленных полифосфатов с циклическими метафосфатами и разветвленными изометафосфатами.
- 2. Способ по п.1, отличающийся тем, что гексаметафосфат вводят при перемешивании со скоростью 5-15 м/с.
