Low-density ash silicon plate produced with industrial wastes as raw materials and production process of ash silicon plate

Abstract

The invention relates to a low-density ash silicon plate produced with industrial wastes, such as coal ash and acetylene sludge, as main raw materials and a production process of the ash silicon plate, in particular to a low-density ash silicon plate produced with industrial wastes as raw materials, and belongs to the technical field of building materials. The low-density ash silicon plate comprises 60-65% of coal ash, 10-15% of cement, 10-15% of acetylene sludge, 5-8% of porcelain clay, 0.5% of iron oxide and 8-10% of wood fiber. The production process comprises the following steps: extraction and preparation of the wood fiber, preparation of plate blank slurry, manufacturing of a plate blank, pressurization and demoulding of the plate blank, steam curing of the treated plate blank, and obtaining of the finished plate. The low-density ash silicon plate provided by the invention is high in performance, relatively low in cost, convenient for construction, relatively high in toughness, and high in moisture resistance; the fire-resistant level is A1; the utilization ratios of the coal ash and calcium carbide sludge reach 65% and 15%, so that the industrial wastes are utilized sufficiently, and environmental pollution is relieved; the protection process is relatively easy to operate; the problem that the construction of a cement plate, a calcium silicate plate and other similar products are difficult is solved.

Description

technical field [0001] The invention relates to a low-density gray silicon board produced by using industrial waste fly ash and carbide slag as main raw materials and a production process thereof, belonging to the technical field of building materials. Background technique [0002] At present, thermal power plants that use coal to generate electricity emit a large amount of fly ash, which occupies land, pollutes the environment, and has formed a public hazard around the power plant. The development and utilization of fly ash is also a top priority. [0003] Gray silica board is a general-purpose building material. Because of its A1-class fire resistance, moisture resistance, sound insulation, and high strength, it can be widely used in building ceilings, partition walls, exterior walls, furniture linings and cabinet linings. And the decorative surface is made of high-parameter fly ash and calcium carbide slag as raw materials, and then processed by special techniques such as...
