Description

Stupalith prepared by a kind of industrial residue and preparation method thereof

Technical field

The present invention relates to technical field of ceramic material, is more particularly stupalith of preparing of a kind of industrial residue and preparation method thereof.

Background technology

Stupalith is the class ceramic made through shaping and high temperature sintering with natural or synthetic compound.It has the advantages such as high-melting-point, high rigidity, high-wearing feature, resistance to oxidation.Can be used as structured material, cutter material, because pottery also has some special performance, can be used as functional materials again.

Industrial residue refers in the industrial production, give off poisonous, inflammable, mordant, communicate illness, have chemically reactive and other harmful solid waste.The solid waste of industrial residue is stored up for a long time and is not only taken a large amount of soil, and can cause the severe contamination to water system and air and harm.The result that mass breaking barren rock is piled up, has damaged large stretch of farmland and backwoods.The harmful slag of industry is stored up for a long time, and through sleet leaching, soluble ingredient permeates downwards from earth's surface with water.Transform to soil mobility, be enriched with harmful substances, make soil property acidifying, alkalization, sclerosis near stockyard. even there is huge sum of money genotype and pollute.Such as, in the soil generally near non-ferrous metals smelting works, lead content is 10 1 40 times of content in normal soil, and copper content is 5-200 times, and Zn content is 5-50 times.These toxic substances enter water body by soil on the one hand, accumulation and absorbed by crops occurs on the other hand in soil, poisons farm crop.Industrial residue and municipal wastes, under the effect of rainwater, snow-broth, flow into rivers,lakes and seas, cause severe contamination and the destruction of water body, can cause larger pollution if industrial residue or rubbish directly poured in river, lake or coastal marine site.The waste residue of reactor, fallout that nuclear explosion produces and the radwaste that jettisons to deep-sea in the world, the ocean that made energy be the isotopic contamination of 0.74EBq (2000 × 10000Ci), Living marine resources suffer very big destruction.Industrial residue and rubbish are in convergent-divergent process, and under the effect of temperature, moisture, some organic substance decomposes, and produce obnoxious flavour, the junk of some corruption distributes bad smell, causes the pollution to air.Such as: during the coal gangue generation spontaneous combustion that pile up like a mountain, fire spreading, is difficult to rescue. and release a large amount of SO2 gas, contaminate environment, in addition, take the flue dust of discharging during incinerating method process solid waste and obnoxious flavour also can atmosphere pollution.

The present invention utilizes industrial residue to prepare stupalith, can carry out recycling, have important economic benefit and social benefit to industrial residue.
