(54) КОМПОЗИЦИЯ ДЛЯ ПРИГОТОВЛЕНИЯ ГАЗОГИПСА(54) COMPOSITION FOR PREPARING GAS GIPS
1one
Изобретение относитс к промышле.нности строительных материалов и мр-жет быть использовано при производстве газогипса на основе гипсовых в жущих веществ дл получени различных изделий.The invention relates to the industry of building materials and can be used in the production of gypsum-based gypsum gypsum for the production of various products.
Известны смеси дл изготовлени газогипса, включающие гипсовые в жущие , карбонатную и кисло.тную добавки и воду l.Known mixtures for the manufacture of gas gypsum, including gypsum in cement, carbonate and acid additives and water l.
Наиболее близка к предлагаемой смесь дл производства газогипса, включающа полуводный гипс и порообразующие добавки: кислотную - сернокислый алюминий и карбонатсодержащую - известн к 2J.Closest to the proposed mixture for the production of gas gypsum, including semi-aquatic gypsum and pore-forming additives: acidic - aluminum sulphate and carbonate-containing - known to 2J.
Недостаток этой смеси - низка прочность газогипса. The disadvantage of this mixture is the low strength of the gas gypsum.
Целью насто щего изобретени вЛйётс повышение прочности газогипса .The purpose of the present invention is to increase the strength of gas gypsum.
Указанна цель достигаетс тем, что смесь, включающа полуводный . гипс, сернокислый алюминий и карбонатсодержащую добавку, содержит в качестве карбонатной добавки шламовый осадок содового производства и дополнительно сульфитно-дрожжевую бражку и стекловолокно при следующем соотношении компонентов,, мас.% :This goal is achieved by the fact that the mixture, including semi-aquatic. gypsum, aluminum sulphate and carbonate-containing additive, contains as a carbonate additive sludge soda production and additionally sulphite-yeast mash and fiberglass in the following ratio of components, wt.%:
Полуводный гипс 55,0 - 65,0 СернокислыйSemi-aquatic gypsum 55.0 - 65.0 Sulfate

Шламовый осадок содового производства0 ,3 - 1,3 Сульфитно-дрожжева бражка 0,2 - 0,6 Стекловолокно 0,1 - 1,9 Sludge slurry soda production0, 3 - 1.3 Sulphite yeast brew 0.2 - 0.6 Glass fiber 0.1 - 1.9
10 Вода Остальное Шламовый осадок образуетс на содовых производствах и включает в себ , мас.%... 5 СаСО 5 - 70-85; Са(ОН),2-4 , Мд(ОН)2 - 0,3-0,6/ CaClj, - О,1510 Water Remaining Sludge residue is formed in soda production and includes, in wt.% ... 5 CASO 5 - 70-85; Ca (OH), 2-4, Md (OH) 2 - 0.3-0.6 / CaClj, - O, 15
0,4,- Nad - 0,2-0,5.0.4, - Nad - 0.2-0.5.
смесь дл изготовлени газогипса приготавливают следующим образом.The mixture for making gas-gypsum is prepared as follows.
Полуводный гипс, шламовый осадок содового производства и стекловолок20 но перемешивают до однородной массы и затвор ют в воде, в котрую предварительно ввод т и тщательно перемешивают сернокислый алюминий и сульфитно дрожжевую бражку.Semi-aquatic gypsum, sludge sludge production and glass fibers20 are mixed until they are homogeneous and shut in water, into which aluminum sulphate and sulphite yeast mash are thoroughly mixed.

В результате реакции между карбонатами , вход щими в состав шламового осадка содового производства, и сернокислым алюминием образуетс углекислый газ, который поризует формо30 вочную смесь.As a result of the reaction between the carbonates, which are part of the sludge sludge soda production, and aluminum sulphate, carbon dioxide is formed, which porous forma mixture.
Содержащиес в составе шламового осадка содового производства примеси хлористого натри и хлористого кальци служат ускорител ми схватывауи формовочной смеси, что позвол ;ёт отказатьс от дополнительного ввода в смесь ускорител схватывани , например, двуводного гипса.The impurities of sodium chloride and calcium chloride contained in the sludge sludge production serve as accelerators for the setting of the molding sand, which makes it possible to refuse additional input into the mixture of the accelerator of setting, for example, two-water gypsum.
Сернокислый алюминий, будучи поризующей добавкой играет также роль ускорител схватьшани и упрочнител пористой структуры материала в результате образовани высокодисперсной- активной гидроокиси алюмини в процессе гидролиза сернокислого алюмини в водном растворе;Aluminum sulphate, being a penetrating additive, also plays the role of accelerator for hardening and hardening the porous structure of the material as a result of the formation of highly dispersed active aluminum hydroxide in the process of hydrolysis of aluminum sulphate in aqueous solution;
Сульфитно-дрожжева бражка, вл сь пластификатором,.позвол ет снизить водо-гипсовое отношение смеси, что, как известно, влечет за собой повышение физико-механических свойст материала. Кроме того, при изготовлении сухой гипсовой штукатурки, гипсо-картонных листов и других слоистых издели{5, введение в смесь сульфитно-дрожжевой бражки повышает адгезию газогипса к картону.The sulphite-yeast brew, being a plasticizer, makes it possible to reduce the water-gypsum ratio of the mixture, which, as is well known, entails an increase in the physicomechanical properties of the material. In addition, in the manufacture of dry gypsum plaster, gypsum-cardboard sheets and other layered products {5, the introduction of a sulphite-yeast brew into the mixture increases the adhesion of the gas-gypsum to cardboard.
