Abstract

The invention discloses a method for producing microcrystalling foam glass with gold tail ore, which comprises the steps of: firstly, putting gold tail ore powder, waste glass powder, fluorite powder, sodium nitrate powder, calcite powder, pure alkali powder, sodium fluosilicate powder and antimonous oxide powder into a mixer to be evenly mixed, and putting into a glass furnace to be melted; draining molten glass liquid into a water pond and water quenching; fishing out water quenched glass, and ball milling and screening with 150 screen mesh to produce the glass powder; and putting the glass powder, foaming agent, ammonium dihydrogen phosphate, iron sesquioxide and manganese dioxide powder into the mixer to be evenly mixed, putting into a foam glass-producing mould, and moving the mould into to a foaming furnace and heating to obtain the microcrystalling foam glass by means of temperature raising, fast cooling and annealing.The method not only is good for recycling waste substance and protecting environment, but also has low producing and foaming temperature and simple production technology, and the produced foaming glass has high structural intensity, low water absorption rate, small density and low heat conduction coefficient.

Description

technical field [0001] The invention relates to a method for manufacturing foam glass, in particular to a method for producing microcrystalline foam glass from gold tailings. Background technique [0002] Foam glass is a new type of environmentally friendly building material with superior performance in heat insulation, sound absorption, moisture resistance, waterproof, and light weight. In practical applications, it is found that the mechanical strength of foam glass is low, which greatly limits the scope of use of foam glass. The method of adding a small amount of additives to the foam glass batch material to precipitate a certain amount of crystals in the foam glass after foaming can greatly improve the mechanical strength of the foam glass. Usually, waste flat glass, waste bottle glass, and fly ash are used as the main raw materials to produce foam glass. Nanjing University uses waste glass and fly ash as the main raw materials, and calcium carbonate as the foaming agent...
