Изобретние относитс к составам гипсовых в жущих и может быть использовано в промышленности строительных материалов при производстве полу-водного гипса из фосфогипса.The inventions relate to gypsum compositions in the living and can be used in the building materials industry in the production of semi-aqueous gypsum from phosphogypsum.
Известна сырьева смесь дл получени гапсового в жущего на основе отходов производства фосфорной кислоты -фосфогипса 1 . Недостатком смеси вл етс наличие в фосфогипсе до 0,5-2 % экстрагированной фосфорной кислоты, котора отрицательно вли ет на продесс кристаллизации полуБодного гипса, снижа его прочность и замедл сроки схватьшани .The known raw material mixture for the production of gaps into a binder based on waste phosphoric acid production - phosphogypsum 1. The disadvantage of the mixture is the presence in phosphogypsum of up to 0.5-2% of extracted phosphoric acid, which negatively affects the progress of crystallization of semi-bodied gypsum, reducing its strength and slowing down the time of setting.
Из известных составов наиболее близьсим к описьшаемому по технической сущности и достигаемому эффекту вл етс другой состав, включающий фосфогипс и карбонат кальци , вводимый дл нейтрализации фосфорной кислоты 2. На основе такого состава получают высококачественный ползводный гипс, однако, при повышенном содержании свободной кислоты в продз сте образуетс большое кодшчество фосфата кальци , которьш замедл ет процесс твердени гипса и снижает прочность изделий.Of the known compositions, another composition, including phosphogypsum and calcium carbonate, introduced to neutralize phosphoric acid 2, is the closest to the technical essence and effect achieved. On the basis of this composition, high-quality half-water gypsum is obtained, however, with an increased content of free acid in production a large amount of calcium phosphate is formed, which slows down the process of gypsum hardening and reduces the strength of the products.
Целью изобретени вл етс повышение прочности гипсовых в жущих на основе фосфогипса. Это достигаетс тем, что смесь дополнительноThe aim of the invention is to increase the strength of gypsum in phosphogypsum-based living. This is achieved in that the mixture additionally

При осуществлении данного технического решени фосфогипс смешивают с карбонатом кальци в необходимом соотношении. Полиметилсилаксановую жидкость ПМС-200 добавл ют после окончани реакции нейтрализации фосфорной кислоты , т.е. перед варкой гипсового в жушего. Варку осушествл ют в гипсоварочном котле.In the implementation of this technical solution, phosphogypsum is mixed with calcium carbonate in the required ratio. The PMS-200 polymethylsiloxane fluid is added after the phosphoric acid has been neutralized, i.e. before cooking plaster in the rain. The cooking is done in a gypsum kettle.
