Изобретение -относитс :к промышленности строительных мате|риал0в.The invention relates to: the building materials industry.
Известен снособ (производства тогпсовых в жущих Путем разложени датолитового концентрата серной ;кислотой с последующей от .мыВКОЙ бор;ной 1КИ€лоты, сушкой и термообработкой .Known snozob (produced to the living ones by decomposing datolite concentrate with sulfuric acid; followed by 1KI boron, drying and heat treatment.
Цель игюбретени - 1повышение прочности искусственного 1калш . и «снижение водопотребности . ГИПСО1ВЫХ в жущих.The purpose of ejaculatory is to increase the strength of artificial 1lksh. and "reducing water demand. HYPSO1 in gnawing.
Дости.гаетс цель тем, что шла.м шерод обработкой 1иодвергают О богаи1.еНИ.1О известными способами, например .отмучпвание:м в проточной воде, в отстойни1ке или отделением частит менее 1 MIK в гидрощиклоне, флотацией Шлама в 1Ирисутст1Вии П0верхрностно-а:кт1ивных веществ -с и радменепием флота1цио нных машин. При отмучива ии шлама в проточной воде (, преимущественно 10) содержание частиц до 10 мк в осадке (кон:центрат) снижают с 30-40% до 10-15%, а содержание SiOa € :20--/25% до 10-15%. Еще болееThe goal is achieved by the fact that the slag and the sludge are treated with 1 and exposed to the bog1 .1O1O by known methods, for example. chemical substances with radmenepia of flotation machines. When otmuchivaja sludge in running water (mainly 10) the content of particles up to 10 microns in sediment (co: centrate) is reduced from 30-40% to 10-15%, and the content of SiOa €: 20 - / 25% to 10- 15%.
