Description

Artificial agate based on coal gangue and manufacture method thereof

Technical field

The invention belongs to artwork production field, is to utilize the industrial solid castoff producing in coal production process specifically---artificial agate and manufacture method thereof that coal gangue is produced.

Background technology

Coal gangue is one of industrial solid castoff that industrial solid castoff ，Shi China quantity discharged of producing in coal production process is maximum, totally piles up more than 3,000,000,000 tons at present, and also annual still in the speed increment with hundred million tons of 1-2.Enterprise generally adopts the mode of air storage to process coal gangue, and this has taken a large amount of soils on the one hand, on the other hand, and objectionable impurities meeting polluted underground water and ambient air in coal gangue, thereby ecotope is produced to serious harm.

For many years, people have adopted multiple technologies to fully utilize coal gangue, as therefrom extracted useful chemical composition, the coal gangue of take is raw material production building materials etc., but all there is defect in these technology to a certain extent, as still can produce industrial solid castoff after extracting Hubeiwan, and when extracting Hubeiwan, generally need to add a certain amount of reactant, the amount of the waste producing so is under many circumstances also more than coal gangue; Also there is the problems such as quality is unstable, energy consumption is high in the application aspect in building materials.

For these reasons, new technology, the novel process of active demand in the market to coal gangue comprehensive utilization.The contriver of this patent is engaged in artificial jade development work from April, 2009, has developed the multiple products such as artificial white jade, black jade, jasper, carbuncle, and excellent property, has broad application prospects in artwork field.

Summary of the invention

The object of the invention is to overcome the defect that conventional art exists, the coal gangue of take has high value-added product as raw material production---artificial agate, thus open up a new approach for the comprehensive utilization of coal gangue.Feature of the present invention is to take coal gangue as main raw material, adds a certain amount of additive simultaneously, through weighing, pulverizing, grinding, batch mixing, stirring, melting, chisel and carve, the technique such as polishing, polishing prepares artificial agate.

Preparation method of the present invention is:

1. the raw materials for production of artificial agate and proportioning:

Coal gangue: 40-85%

Silica powder: 20-60%

Zinc oxide: 1-15%

Water glass: 1-30%

Above-mentioned raw materials can be used also simultaneously and can partly use, according to the performance requriements of product and production cost are determined.

2. the preparation technology of artificial agate is:

(1) weigh on request various raw materials;

(2) by block raw material crushing, grinding;

(3) various raw materials are put into container and mix and stir, make material composition even;

(4) pour the raw material mixing into crucible, put into smelting furnace and carry out melting, be characterized as: raw material is put into crucible, at room temperature pack smelting furnace into, with stove, heat up; Heating temperature is 800-1650 ℃, insulation 2-30 hour; Furnace cooling, in process of cooling, fire door is closed all the time;

(5) product is cooled to after room temperature, from stove, takes out;

(6) from crucible, take out artificial agate, then according to the difference of concrete product chisel and carve, polishing, glossing, finally obtain finished product.

     

Beneficial effect of the present invention:

Artificial agate quality exquisiteness prepared in accordance with the present invention is tough and tensile, gloss is gentle soft, and there is good mechanical property, as higher hardness, toughness and wear resistance, high thermal resistance, erosion resistance, weathering resistance etc., can be used for artwork field, have broad application prospects.

The present invention be take coal gangue and is had high value-added product as production raw material production, has realized the high value added utilization to coal gangue, for a new way has been opened up in the comprehensive utilization of industrial solid castoff.

Raw material sources of the present invention are extensive, and the additive of use is for Chemicals common on market, cheap.

Aspect preparation technology, preparation technology of the present invention is simple, lower to the requirement of equipment, and operator's technical ability is not had to particular requirement yet, and common laborer can operate.

In sum, the present invention has higher practicality and application value.
