Description
Изобретение касаетс способа получени термоизол ционного материала из силикатов щелочных металлов путем нагревани при температурах , при которых происходит вспучивание силиката.The invention concerns a process for the preparation of a thermally insulating material from alkali metal silicates by heating at temperatures at which the silicate is expanded.
В цел х получени конечного продукта в форме шариков, авторы насто щего изобретени предлагают измельчать исходный силикат до его термической обработки.In order to obtain the final product in the form of beads, the authors of the present invention propose to grind the starting silicate prior to its thermal treatment.
В зависимости от намеченных к получению размеров шариков готового продукта силикат натри или кали измельчаетс до гранулометрического состава от 0,1 до 2 мм. Измельченный порошок подвергаетс термической обработке при температуре не свыще 650°, в результате которой отдельные зерна вспучиваютс , во много раз увеличиваютс в объеме, образу тельца шарообразной формы, имеющие однородную пористую структуру.Depending on the size of the beads of the finished product to be obtained, sodium silicate or potassium silicate is ground to a particle size distribution of 0.1 to 2 mm. The crushed powder is subjected to heat treatment at a temperature not higher than 650 °, as a result of which individual grains swell, many times increase in volume, forming a spherical body with a uniform porous structure.
Дл предотвращени слипани отдельных зерен силиката при термической обработке предлагаетс опыливать их порошком какого-либо термостойкого материала, например, слюды, талька, диатомита и т. п.In order to prevent individual silicate grains from sticking together during heat treatment, it is suggested to dust them with a powder of some heat-resistant material, for example, mica, talc, diatomite, etc.
Полученный материал отличаетс малым объемным весом (от 25 до 75 KZlM, в зависимости от размеров щариков) и высокими теплозащитными свойствами, обусловленными пористой структурой материала и сферической поверхностью.The resulting material is distinguished by its low volumetric weight (from 25 to 75 KZlM, depending on the size of the balls) and high heat-shielding properties due to the porous structure of the material and the spherical surface.
Ири желании повысить механическую прочность или придать материалу какие-либо особые свойства (водостойкость, огнестойкость и т. д.) в массу предварительно ввод т соответствующие наполнители.If you wish to increase the mechanical strength or impart any special properties to the material (water resistance, fire resistance, etc.), appropriate fillers are introduced into the mass.
По своей структуре полученный материал совершенно однороден, так как благодар малому размеру зерен силиката (от 0,1 до 2 м.м температура во всех зонах остаетс во врем термической обработки однородной, и тепло проникает через всю толщу.The structure of the material obtained is completely homogeneous, since, due to the small size of the silicate grains (from 0.1 to 2 m. M, the temperature in all zones remains homogeneous during the heat treatment and heat penetrates through the entire thickness.
Предлагаемый материал может примен тьс при температуре до 650 при полной сохранности конструкции.The proposed material can be used at temperatures up to 650 with complete safety of the structure.
Материал может примен тьс как засыпна изол ци и в виде формованных изделий. В последнем случае шарики смешиваютс с соответствующими в жущими материалами органического или неорганического происхождени .The material can be used as a charge of insulation and in the form of molded products. In the latter case, the balls are mixed with corresponding organic or inorganic materials.
