Abstract
Способ получения гипсового вяжущего из неохлажденного кислого отхода производства фтористого водорода, включающий нейтрализацию кислого фторангидритового отхода известьсодержащим агентом и измельчение, отличающийся тем, что одновременно в процессе измельчения вводят воду в количестве 10,0-14,0 мас.% от кислого отхода, полученное вяжущее при этом выдерживают не менее 5 ч в бункере томления.A method of producing a gypsum binder from uncooled acidic waste of the production of hydrogen fluoride, comprising neutralizing the acidic fluorohydrite waste with a lime-containing agent and grinding, characterized in that at the same time during the grinding process, water is added in an amount of 10.0-14.0 wt.% Of the acidic waste, the resulting binder at the same time, they withstand at least 5 hours in the languishing hopper.
