heat-insulating materials. SUBSTANCE: raw mixture comprises the following components, wt. -%: porous granules of fraction 2-10 mm, 45-55; swollen vermiculite of fraction 1-2 mm, 3-10; clay, 3-8; water glass, 30-40. Porous granules can be made as capsules, for example, from claydite, agloporite, slaggy pumic, schungisite, tripolite and other materials based on alumosilicates. Raw mixtures can be used for making heat- insulation used in industrial heat units, in part, for heat-insulation of internal cavities of carcasse covers and combustion chambers of gas turbine units using for main-line methane pumping. EFFECT: valuable properties of mixture. 2 cl, 2 tbl, 2 dwg, 3 ex |
