Illite is a group of closely related non-expanding clay minerals. Illite is a secondary mineral precipitate, and an example of a phyllosilicate, or layered alumino-silicate. Its structure is a 2:1 sandwich of silica tetrahedron (T) – alumina octahedron (O) – silica tetrahedron (T) layers. The space between this T-O-T sequence of layers is occupied by poorly hydrated potassium cations which are responsible for the absence of swelling. Structurally, illite is quite similar to muscovite with slightly more silicon, magnesium, iron, and water and slightly less tetrahedral aluminium and interlayer potassium. The chemical formula is given as (K,H3O)(Al,Mg,Fe)2(Si,Al)4O10[(OH)2,(H2O)], but there is considerable ion (isomorphic) substitution. It occurs as aggregates of small monoclinic grey to white crystals. Due to the small size, positive identification usually requires x-ray diffraction or SEM-EDS (automated mineralogy) analysis. Illite occurs as an altered product of muscovite and feldspar in weathering and hydrothermal environments; it may be a component of sericite. It is common in sediments, soils, and argillaceous sedimentary rocks as well as in some low grade metamorphic rocks. The iron rich member of the illite group, glauconite, in sediments can be differentiated by x-ray analysis.
Flame ablation-resistant fireproof coating as well as preparation method and application thereof
The invention discloses a flame-ablation-resistant fireproof coating as well as a preparation method and application thereof, and belongs to the technical field of fireproof coatings. The coating comprises 20-60 parts of a film forming matter, 5-25 parts of indirect ceramic forming filler, 10-30 parts of an acid source and 5-15 parts of a gas source, the indirect ceramic forming filler comprises any one or more of feldspar, illite, kaolinite, montmorillonite, calcium silicate and magnesium silicate. The indirect ceramic forming filler is decomposed into a ceramic forming material at high temperature, and at the moment, the fireproof coating expands to form an expansion layer; the ceramic forming material in the expansion layer further reacts under the action of high-temperature flames, especially the ceramic forming material outside the expansion layer facing high temperature, to generate a ceramic substance, so that the surface ceramization of the fireproof coating is controllable, and the ceramization effect of the expansion layer after the coating is fully expanded is achieved; the problem that the fireproof performance is reduced due to the fact that a coating expansion layer forms a hard shell layer too early when the high-temperature-resistant performance of the fireproof coating is improved through a ceramic method is solved.
