Description
Известен епоеоб получени дисперслого двуводного гипса при десульфатизации малнезиальной рапы известью. Также известно получение строительного гипса (полугидрата) путем варки двуводного гипса в растворах солей с последующей сушкой и размолом.It is known to produce dispersible two-water gypsum by desulphating a small brine with lime. It is also known to obtain gypsum (hemihydrate) by boiling dihydrate gypsum in salt solutions, followed by drying and grinding.
Предложенный способ позвол ет упростить технологический процесс изготовлени изделий из дисперсного гипса за счет исключени сушки и размола, дл чего издели формуют путем прессовани под давлением 60-100 атм непосредственно из вареного и обмытого гипса, без предварительного выделени полугидрата.The proposed method allows us to simplify the technological process of manufacturing products from dispersed gypsum by eliminating drying and grinding, for which the products are molded by pressing under a pressure of 60-100 atm directly from boiled and washed gypsum, without first isolating the hemihydrate.
Таким образом, после варки дисперсного гипса в 50%-ном растворе хлористого кальпи в течение одного часа и получени соотношени объема раствора к весу пасты 3 : 1 проводились вакуум-фильтраци и отмывка пасты гипса на фильтре водой в соотношении воды к пасте гипса Зт2:1. Непосредственно затем проводилось прессование при давление 60-100 атм с отжимом воды. Предел прочности полученных образцов в 28-дневпом возрасте 100-150 кг/см Предмет изобретени Thus, after boiling dispersed gypsum in a 50% solution of calpy chloride for one hour and obtaining a ratio of solution volume to a paste weight of 3: 1, vacuum filtration was performed and washing the gypsum paste on the filter with water in a ratio of water to gypsum paste D2: 1 . Directly then, pressing was carried out at a pressure of 60-100 atm with water extraction. The ultimate strength of the obtained samples at 28 days of age is 100-150 kg / cm.
Способ изготовлени изделий из дисперсного гипса, получаемого варкой в растворах солей продукта десульфатизации магнезиальной рапы известью, отличающийс тем, что, с целью упрощени технологического процесса за счет исключени стадий сушки и размола, издели формуют путем прессовани при давлении 60-100 атм непосредственно из вареного и обмытого гипса без предварительного выделени полугидрата.A method of manufacturing products from dispersed gypsum obtained by boiling lime sulphate of the magnesia brine in salt solutions, characterized in that, in order to simplify the process by eliminating drying and grinding steps, the product is molded by pressing at a pressure of 60-100 atm directly from washed gypsum without prior isolation of the hemihydrate.
