Description
Шамот низкожженный4О--50 Кварцевый песок15-25 Ганна полукисла ЗО-4,0 и кроме того,/ Коксик,3-3 а сверх 100% Жидкое стекло3-5 Сульфитно-спиртова барда, не менее5 3 J i-ia основе этой композиции получают штучные прессованные издели с сравннтеиьио низкими теплоизол ционными свойствами, кроме того, она непригодна дл нанесени на защищаемую поверх ность торкретированием. Пень изобретени - улучшение тепло изолйлионных свойств композиций и обес печение возможности нанесени ее торкретированием на защищаемую поверхность . Поставленна цель достигаетс тем, что композици дл футеровки тепловых агрегатов, включающа шамотный порошок , кварцевый песок, глину и жидкое стекло, дополнительно содержит асбест, керамзит и кремнефтористый натрий при следующем соотношении компонентов, вес.%: Шамотный порошок40-49 Кварцевый песок25 30 Глина5-11 74 Жидкое стекло5-7 Асбест3-10 Керамзит. .5. О Кремнефтористый натрий 3-5 Дл приготовлени шамотного порошка берут куски или бой алюмосиликатного кирпича или кускового, шамота и размалывают до крупности зерен не более 5 мм. Огнеупорную глину измельчают до крупности зерен не более 1 мм. Асбест предварительно распушивают, пропуска через дезинтегратор. Кремне- фтористый натрий, используемый дл интенсификации процесса твердени , представл ет собой тонкодисперсный порошок, и не требует предварительной подготовки. В качестве в зущего примен ют раствор жидкого стекла плотностью 1280кг/мГ Были изготовлены композиции, из ко тррых прессовали образцы. Технологи изготовлени образцов аналогична технологии , описанной в . В таблице приведены характеристики физических свойств образцов из полученHbjx огнеупорных масс. Предлагаема композици позвол ет наносить ее торкретированием на защищаемую поверхность (до 500°С) и обладает большей стойкостью к стекольной шихтной пыли и продуктам горени .Low-burnt fireclay4O - 50 Quartz sand15-25 Gunn half-acid ZO-4.0 and also / Koksik, 3-3 and over 100% Liquid glass3-5 Sulfite-alcohol bard, not less than 5 3 J i-ia this composition is obtained piece pressed products with comparatively low thermal insulation properties; in addition, it is not suitable for spraying onto the surface to be protected. The stump of the invention is the improvement of the thermal insulating properties of the compositions and the possibility of its application by gunning on the surface to be protected. The goal is achieved by the fact that the composition for lining thermal units, including chamotte powder, quartz sand, clay and water glass, additionally contains asbestos, expanded clay and sodium silicofluoride in the following ratio, wt.%: Chamotte powder 40-49 Quartz sand 25 30 Clay5- 11 74 Liquid glass5-7 Asbestos 3-10 Expanded clay. .five. О Sodium silicofluoride 3-5 To prepare chamotte powder, take chunks or a battle of aluminosilicate brick or lump, chamotte and grind to a grain size of not more than 5 mm. Refractory clay is crushed to a grain size of not more than 1 mm. Asbestos is predrung, passes through the disintegrator. Sodium fluoride, used to intensify the hardening process, is a fine powder and does not require prior preparation. A liquid glass solution with a density of 1280 kg / mG was used as the composition. Compositions were made from which samples were pressed. Sample fabrication techniques are similar to those described in c. The table shows the characteristics of the physical properties of the samples from the obtained Hbjx refractory masses. The proposed composition allows to apply it by gunning to the surface to be protected (up to 500 ° C) and is more resistant to glass blend dust and combustion products.
