Description
Глпсовые строительные детали отличаютс невысокой механической прочностью и водонеустойчнвостыо . Попытки увеличени прочности и водоустойчивости гипсовых изделий путем пропитки жидким стеклом не увенчались успехом и лаже привели к отрицательным результатам , вследствие образовани дес тиводното сульфата натри , который при кристаллизации увеличиваетс в объеме и вызывает разрзтпение изделий.Construction details are low mechanical strength and water resistant. Attempts to increase the strength and water resistance of gypsum products by impregnation with liquid glass did not succeed and even led to negative results, due to the formation of one or two sodium sulfate, which increases in volume during crystallization and causes the products to disintegrate.
Авторами установлено, что эти отрицательные результаты могут быть устранены, если ввести в массу небольшое количество хлористого натри дл понижени температуры перехода глауберовой соли и дл торможени реакции меледу жидким стеклом и гипсом.The authors found that these negative results can be eliminated if a small amount of sodium chloride is introduced into the mass to lower the transition temperature of the Glauber's salt and to slow down the reaction with meleda with liquid glass and plaster.
Соответственно этому был разработан новый способ получени формовочной массы, по которому измельченный и просе нный полуводный гипс смешивают с просе нной окисью кальци (негашеной известью ), измельченной и просе нной обожженной глиной (или с измельченным боем строительногоAccordingly, a new method has been developed to obtain a molding mass, in which crushed and sifted semi-aquatic gypsum is mixed with sieved calcium oxide (quicklime), crushed and sieved calcined clay (or crushed
кирпича) и небольшим количеством поваренной соли. Всю массу тшательно перемешивают в сухом состо нии , затем увлажн ют, перемешивают и смешивают с жидким стеклом, имеющим модуль 3,3-3,8. После пере.мешивани массу формуют , высушивают при температуре 40-60° и направл ют на склад.brick) and a small amount of salt. The whole mass is thoroughly mixed in a dry state, then moistened, mixed and mixed with liquid glass having a module of 3.3-3.8. After mixing, the mass is molded, dried at a temperature of 40-60 ° and sent to the warehouse.
Преи.мушеством способа вл ютс : увеличение механической прочности гипсовых строительных деталей , увеличение атмосфероустойчивости , повышение огнестойкости, устранение пластической деформации , ускорение процесса изготовлени строительных деталей, возможность изготовлени деталей в кустарных услови х (восстановительное строительство). Рецепт:The advantages of the method are: an increase in the mechanical strength of gypsum building parts, an increase in weather resistance, an increase in fire resistance, the elimination of plastic deformation, an acceleration of the process of manufacturing building parts, the possibility of producing parts in artisanal conditions (restoration construction).
