Description

A kind of rhinestone and manufacture method thereof

Technical field

The invention belongs to jewelry, artwork production field, is a kind of rhinestone and manufacture method thereof of producing with Inorganic Chemicals specifically.

Background technology

The quality of diamond is hard, and fire is color strong, bright and glittering, very popular since ancient times, but the diamond resource-constrained of natural output, can not meet the growing needs of people, and therefore people adopt synthetic technology to manufacture rhinestone.

At present, on market, there is a lot of artificial diamond productions, be widely used in the production of jewellery, artwork, but these product majorities are take cubic zirconia and lead glass as raw material, and cubic zirconia fire is color relatively good, and specific refractory power is high, bright and glittering, approach rough diamond, but its fusing point is very high, is difficult to fusing and processing, the fusing point of lead glass is lower, be easy to fusing and processing, but its specific refractory power is low, fiery coloured silk is not strong.

Summary of the invention

The object of the invention is the weak point in order to overcome currently available products, with Inorganic Chemicals common on market, produce the rhinestone with premium properties, it is characterized in that take inorganic chemical product as main raw material, through weighing, pulverizing, grinding, batch mixing, stirring, melting, cutting, polishing, glossing, prepare rhinestone.

Preparation method of the present invention is:

1. raw materials for production and proportioning:

PbO：10-60%

ZrO ₂：15-30%

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

2. the preparation technology of rhinestone 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 500-2200 ℃, insulation 1-15 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 rhinestone, then according to the difference of concrete product cut, polishing, glossing, finally obtain finished product.

     

Beneficial effect of the present invention:

Rhinestone prepared in accordance with the present invention has higher specific refractory power, and fire is color strong, bright and glittering, and fusing point is lower, easily melts and processes.Have high rigidity, high tenacity and good wear resistance, high thermal resistance, erosion resistance, weathering resistance etc., performance is satisfactory simultaneously.

The present invention use industrial chemicals composition accurate, fluctuating range is little, therefore the steady quality of rhinestone, easily control.In addition, these raw materials are Chemicals common on market, cheap, and production cost is low.

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.

Product of the present invention can be used for the fields such as jewellery, artwork, has broad application prospects.
