Description
Изобретение относитс к производству теплоизол ционных материалов.The invention relates to the manufacture of thermal insulation materials.
Цель изобретени - повышение прочности , снижение стоимости и расширени технологических возможностей.The purpose of the invention is to increase the strength, reduce the cost and expand technological capabilities.
Из смеси формовали образцы - кубики 10x10x10 см путем свободной укладки их в формы с дес тисекундным вибрированием на стандартной лабораторной виброплощадке . Далее формы со смесью помещали в сушильный шкаф и прогревали при 250°С в течение 1,5 ч. После остывани образцов определ ли их среднюю плотность, прочность на сжатие, коэффициент водостойкости.Samples — cubes 10x10x10 cm — were molded from the mixture by free-laying them in forms with ten-second vibrations on a standard laboratory vibrating plate. Next, the forms with the mixture were placed in an oven and heated at 250 ° C for 1.5 hours. After the samples cooled down, their average density, compressive strength, and water resistance coefficient were determined.
Примеры композиций и свойства полученных материалов представлены в таблице .Examples of compositions and properties of the materials obtained are presented in the table.
Из таблицы видно, что оптимальным составом по показател м средней плотности и прочности на сжатие можно считать композицию , содержащую, мас.%: борна кислотаThe table shows that the optimal composition in terms of average density and compressive strength can be considered a composition containing, in wt.%: Boric acid
3; силикат-глыба 55; известн к 10; вода остальное .3; silicate block 55; known to 10; water the rest.
Материалы, полученные на основе предлагаемой композиции ,более прочные, более дешевые (в 1,5 раза), менее энергоемки и более технологичны.The materials obtained on the basis of the proposed composition, more durable, cheaper (1.5 times), less energy-intensive and more technological.
