Description
Способы изготовлени шамотноизвестковых строительных изделийиз амеси глины с известн ком посредством обжига, совместного тонкого помола, увлажнени , вылеживани , формовани и гидротермальной обработки известны. В насто щее врем при содержании в глинах и суглинках крупных .включений известн ка в количестве более 2 - 4 о сырье бракуетс и считаетс непригодным дл производства.Methods for making fireclay building products from lime clay and limestone by roasting, fine grinding, wetting, curing, molding and hydrothermal processing are known. At present, when content in clay and loam of large inclusions of limestone in the amount of more than 2-4, raw materials are rejected and are considered unsuitable for production.
Согласно насто щему изобретению , глин ное сырье с карбонатными включени ми и добавлением от 10 до 20% известн ка обжигаетс при температуре от 950 до 1000-. Продукт обжига замачиваетс . При этом происходит гидратаци окиси кальци , разруп1аю1ца комки образовавшегос шамота . Гидратированный продукт обжига размалываетс , просеиваетс , увлажн етс до 10- 14 б и в таком виде вылеживаетс . Полученна таким образом смесь шамотного порошка с гашеной известью имеет активность пор дка 6 - 10 и в нересчете ка окись кальци и из нее обычными методами формуют издели , подвергаемыеAccording to the present invention, clayey raw materials with carbonate inclusions and the addition of 10 to 20% limestone are burned at a temperature of 950 to 1000-. The calcine is soaked. When this occurs, calcium oxide hydrates, breaking up the lumps of the formed chamotte. The hydrated calcination product is milled, sieved, moistened to 10-14 b, and cured in this form. The mixture of fireclay powder with hydrated lime thus obtained has an activity of from 6 to 10 and, in addition, calcium oxide is used to form articles from it using conventional methods.
в заключение гидротермальной обработке под давлением от 8 до 16 aniM. В результате получаютс издели с объемным весом от 1,6 до 1,65 г с.)г , с прочностью на сжатие от 100 до 200 . Описанный способ позвол ет использовать дл производства строительных материалов некондиционное глин ное сырье, которое сильно засорено крупными карбонатными включени ми в количестве до . Это существенно расшир ет сырьевую базу дл производства строительных изделий, что позвол ет более широко использовать местные сырьевые ресурсы и тем ликвидировать дорогостоющие дальние перевозки строительных изде ЛИЙ. (г 1 О до 30 °о обожженной массы могут быть заменены той же высуп енной и размолотой необожженной глиной, а также часть глины можно вводить в смесь в виде шликера.finally hydrothermal treatment under pressure from 8 to 16 aniM. The result is a product with a bulk weight from 1.6 to 1.65 g. C) g, with compressive strength from 100 to 200. The described method makes it possible to use substandard clay raw materials for the production of building materials, which is heavily clogged with large carbonate inclusions in the amount of up to. This significantly expands the raw material base for the production of building products, which allows for a wider use of local raw materials and thereby eliminates the costly long-distance transportation of building materials. (g 1 o up to 30 ° o baked mass can be replaced with the same spiked and ground unburned clay, and also part of the clay can be introduced into the mixture in the form of a slip.
