Problems solved by technology

[0005] Now, many countries prohibit the hunting of elephants and trade in ivory. Therefore, the number of natural ivory is getting smaller and smaller, which is far from meeting people's growing demand for ivory handicrafts. In order to solve this contradiction, some people use other animal ivory Teeth instead of ivory, or using synthetic techniques to create artificial ivory
[0006] However, products carved with the teeth of other animals will turn yellow and crack after being placed for a long time, and the value will be greatly reduced
Most of the artificial ivory currently on the market is made of organic matter (such as unsaturated resin) as the main raw material, and at the same time adding aluminum hydroxide and other fillers. Because their chemical composition and microstructure are relatively different from natural ivory, these products The performance is also relatively poor, such as color, gloss, hardness, wear resistance, high temperature resistance, corrosion resistance, weather resistance, etc., are vulnerable to various factors (mechanical, high temperature, corrosion, natural light) during use ) to cause deterioration or damage

Abstract

The invention belongs to the field of artware and jewelry production, and in particular relates to the artificial ivory production by utilization of desulfurized gypsum. The invention is characterized in that raw materials comprise all or part of desulfurized gypsum, potassium fluotitanate, lithium oxide, calcium fluoride and lead oxide. A preparation method comprises the following steps: (1) weighing; (2) crushing and grinding; (3) mixing and stirring; (4) melting; (5) carving, grinding and polishing. The artificial ivory prepared by the invention is similar to natural ivory, has white color, delicate and firm texture, mild and soft luster, high hardness, high toughness and excellent wear resistance, high temperature resistance, corrosion resistance and weather resistance; the product has satisfactory decorative performance and the mechanical properties, can be used in the field of artware and jewelry. The invention achieves high added value utilization of desulfurized gypsum, and has broad application prospect.

Description

technical field [0001] The invention belongs to the field of handicraft and jewelry production, in particular to artificial ivory produced by using desulfurized gypsum, an industrial solid waste produced by a power plant, and a manufacturing method thereof. Background technique [0002] Desulfurization gypsum is a solid waste produced in the production process of thermal power plants, with an annual output of tens of millions of tons. Enterprises generally treat desulfurized gypsum in the form of stacking in the open air, which takes up a lot of land and pollutes the surrounding ecological environment on the other hand. [0003] Over the years, people have realized that desulfurized gypsum is also an important resource, and have adopted a variety of technologies to comprehensively utilize it. At present, the main utilization methods include using desulfurized gypsum as raw material to produce construction gypsum powder, gypsum blocks, cement Retarders, etc., but most of the...
