The invention discloses a foamed
flue gas desulfurization
gypsum heat-preservation plate based on foamed glass wastes. The foamed
flue gas desulfurization
gypsum heat-preservation plate consists of the following components in parts by weight: 40 parts of
flue gas desulfurization
gypsum, 20 parts of
coal ash, 0-40 parts of ore
powder, 0.25-0.5 part of a
foaming agent, 0-12 parts of foamed glass leftovers, 0-40 parts of steel
slag, 70 parts of water, 2 parts of
lime, 0.5-1 part of a water reduction agent and 2 parts of an early strength agent. Waste foamed glass is crushed, screened and graded into
artificial light aggregate of different particle sizes, and is mixed with a
flue gas desulfurization gypsum based foamed concrete blank to prepare a heat-preservation plate. The foamed
flue gas desulfurization gypsum heat-preservation plate disclosed by the invention has a heat conduction coefficient of 0.06-0.09w / m*k, pressure strength up to 0.5MPa or greater and a
drying apparent density of310-450kg / m<3>. According to the foamed
flue gas desulfurization gypsum heat-preservation plate, the waste foamed glass and wastes such as
flue gas desulfurization gypsum and
coal ash in thermal powerplants are turned into effective resources and are recycled, in addition, a production process is energy-saving and
environmentally friendly, environment
pollution can be reduced, meanwhile, types ofenergy-saving heat-preservation wall materials can be enriched, and the environmental-friendly degree of an inorganic light material can be increased.
