Pulverized coal ash is a low extinguished after constituted like pozzolana mixed. It was extinguished coal plants will be ground into pulverized coal 100 microns or less, with a warm-up atmosphere injected into the furnace to form a suspension off, low-temperature occurrence thick cloud of smoke small amounts of non-combustible material, install the trap to get through the dust fly ash. The chemical composition of fly ash is similar to clay, minor identity as silica, aluminum oxide, ferric oxide, calcium oxide and unburned carbon. Fly ash is a coal-fired power plants are the major solid waste discharge.
Lytag is fly ash as the main raw material (85%) about the incorporation of the right amount of lime (or carbide slag), gypsum, additives, etc., by measurement, ingredients, forming, hydration and hydrothermal synthesis reaction or An artificial lightweight aggregate reaction and made of natural water hard. Ceramic has excellent properties such as low density, high pressure tube, high porosity, softening coefficient, good frost resistance, excellent alkali aggregate reaction and so on. Especially due to the small high density ceramic density porous internal morphology, composition more uniform, and possessed a certain strength and robustness, which has a lightweight, corrosion-resistant, frost, seismic and good barrier properties (insulation, heat insulation, sound insulation, separated tide) and other multi-features. The use of these excellent properties of ceramic, it can be widely used in building materials, gardening, food and beverage, fire-resistant insulation materials, chemical, oil and other departments, applications increasingly widespread, continues to expand. At the beginning of the invention and production of ceramic proppants , it is mainly used for building materials, as technology continues to evolve and people on a deeper understanding of the performance of ceramic, ceramic applications already exceeded the scope of the traditional building materials, expanding its use of new fields. Ceramic building materials now in use, and has fallen from 100% to 80%, applied in other areas, accounted for 20%. With the continuous development of new uses for ceramic, its share in other areas will gradually increase.
