Summary of the invention
The object of the present invention is to provide a kind of oil shale slag lightweight high-strength haydite and production method, solve the problems such as the approach of dissolving of the in short supply and industrial solid castoff of present haydite market starting material.
Technical scheme of the present invention is:
1. along with the rising steadily of oil and fuel price, utilize oil shale to carry oil and the generating interests are huge, utilize in the process at this to produce a large amount of waste residues, deposit these waste residues and not only take a large amount of soils, simultaneously also contaminate environment.And building material industry is sharp useless rich and influential family, utilizes these waste residues to produce building material-haydite, sharp useless environmental protection, economic benefit and obvious social benefit.2. according to the roasting principle of haydite, consider the synthesis result of solid phase, liquid phase, gas-phase reaction, create three prerequisites of haydite roasting: the one, in the expansion temperature scope, produce expanding gas; The 2nd, the liquid phase parcel of suitable viscosity is arranged after expanding gas produces and suppress gas evolution; The 3rd, suitable maturing temperature scope and time.Rationally controlling well under the situation of above three prerequisites, just can produce light high-strength haydite.
Expansion mechanism of the present invention:
If make oil shale slag particulate materials produce expansion, should possess following two conditions simultaneously through roasting through preparation: the one, can in the expansion temperature scope, produce expanding gas; The 2nd, the liquid phase parcel that have suitable viscosity is to suppress gas evolution.From above-mentioned two conditions as can be seen, haydite expansion at high temperature is solid phase, liquid phase, gas phase three phase dynamic equilibrated result, only possesses this two conditions, could obtain the good homogeneous porous light high-strength haydite that expands.In the haydite materials, adding the material that heat energy produces gas has a lot, and as the crystal water of organism, carbonate, sulfide, ferriferous oxide and some mineral etc., above-mentioned various materials produce the severe degree of gas and also have nothing in common with each other under differing temps.Therefore, in the differing temps scope, gas is produced by certain or several material, is not fixed, and the generation gas reaction is as follows:
(1) discharge its volatile matter and destructive distillation product at 400～800 ℃ of organism, be rapidly heated or anoxia condition under, organism is wanted complete oxidation, temperature will can be expressed as near the raw material softening temperature:
C+O
2 →CO
