Abstract
The invention belongs to the field of handicraft production, and in particular relates to artificial jade produced by utilizing flue-gas desulfurization (fgd) gypsum. The artificial jade is characterized by comprising all or a part of the following raw materials: fgd gypsum, quartz powder, lead oxide, calcium fluoride, sodium carbonate, sodium silicate and pigment. The preparation method comprises the following steps: (1) weighing; (2) crushing and grinding; (3) mixing and stirring; (4) melting; (5) carving, burnishing and polishing. The artificial jade prepared by the method is smooth and hard in texture, mild and gentle in luster, has excellent mechanical performances, can be used in handicrafts and other fields, and has a wide application prospect. Products with high additional values can be produced from fgd gypsum as a raw material, high-additional-value utilization of the fgd gypsum can be realized, and a new means is opened up for comprehensive utilization of industrial solid wastes.
Description
Technical field
The invention belongs to artwork production field, is the industrial solid castoff that utilizes power plant to produce specifically---artificial jade and manufacture method thereof that desulfurated plaster is produced.
Background technology
Desulfurated plaster is the solid waste that thermal power plant produces in process of production, and annual quantum of output is up to several ten million tons.Enterprise generally adopts the formal layout desulfurated plaster of air storage, and this has taken a large amount of soils on the one hand, on the other hand, also can pollute the ecotope of periphery.
For many years, it has been recognized that desulfurated plaster is also a kind of important resource, and adopt multiple technologies to fully utilize it, the at present main approach that utilizes comprises with desulfurated plaster as raw material production building gypsum plaster, gypsum block, cement setting retarder etc., but these utilize approach majority to belong to extensive and utilize, value-added content of product is lower, and the economic benefit of generation is limited.
For these reasons, in the market in the urgent need to new technology, novel process to desulfurated plaster comprehensive utilization.The contriver of this patent is engaged in the development work of utilizing industrial solid castoff to prepare artificial jade from April, 2009, develops multiple product, 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, there is high value-added product take desulfurated plaster as main material production---artificial jade, thus open up a new approach for the comprehensive utilization of desulfurated plaster.Feature of the present invention is take desulfurated plaster as main raw material, adds a certain amount of additive simultaneously, through weighing, pulverizing, grinding, batch mixing, stirring, melting, chisel and carve, polishing, glossing prepare artificial jade.
Preparation method of the present invention is:
1. the raw materials for production of artificial jade and proportioning:
Desulfurated plaster: 35-85%
Silica powder: 15-45%
Plumbous oxide: 10-35%
Calcium Fluoride (Fluorspan): 5-25%
Soda ash: 5-25%
Water glass: 10-30%
Pigment: 1-15%
Above-mentioned raw materials can use also simultaneously and can partly use, and determines according to the performance requriements to product and production cost.
2. the preparation technology of artificial jade 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, heat up with stove; Heating temperature is 800-1650 ℃, is incubated 3 hours; 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 jade, then according to the difference of concrete product chisel and carve, polishing, glossing, finally obtain finished product.
Beneficial effect of the present invention:
Artificial jade 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 the field such as jewellery, artwork, have broad application prospects.
The present invention has high value-added product take desulfurated plaster as production raw material production, has realized the high value added utilization to desulfurated plaster, 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.
