preparation example Construction

[0031] A method for preparing stone-like glass. The raw materials are configured according to the requirements, and the raw materials are passed into the melting part, mixed and melted to form a molten glass liquid, and then the glass liquid is passed into the cooling part, where it is homogenized, clarified, and air bubbles are discharged. Then discharge the molten glass to the forming part, anneal after forming, and finally take out the imitation stone glass, wherein the temperature in the forming part is kept at 1320°C to 1400°C, and the glass liquid is stored in the forming part for 1 to 10 hours. After cooling down, anneal after forming, and finally take out the imitation stone glass. The heat preservation process of the forming part is conducive to the growth of crystal nuclei. Since the raw material may stick in the mold cavity during the crystallization process, the mold cavity needs to be destroyed, so the mold cavity can be made of low-cost heat-resistant ceramics, o...

Abstract

The invention proposes a crystalline stone imitation material for making handicrafts, and the proportion of crystals is about 40% to 60%. It has excellent mechanical properties, opaque, light green or white appearance, and good gloss. It is an excellent imitation stone material. Its molding viscosity is low, and it can be used to make imitation stone Buddha statues, imitation stone seals, imitation stone sculptures, etc.

Description

technical field [0001] The invention relates to a microcrystalline stone imitation material, in particular to a crystalline stone imitation material for making handicrafts. Background technique [0002] Microcrystals consist of a glass phase and a crystalline phase. Glass-ceramic is similar to stone in appearance, but its strength and hardness are superior to ordinary marble. It can be poured or sintered, so it can be made into handicrafts just like ceramic products. [0003] 200710051220.7 relates to lead-free crystal glass, which contains: SiO 2 : 40-60%, B 2 o 3 : 0~5%, Li 2 O: 0~5%, Na 2 O: 0~10%, K 2 O: 5-15%, TiO 2 : 10-20%, ZnO: 0-5%, ZrO 2 : 0~5%, KHF 2 : 3~10%, Al 2 o 3 : 1.5~5%, CaO: 0.5~5%, Sb 2 o 3 : 0~1%. The crystal glass is used to make glass handicrafts. In the production of handicrafts, in addition to the color requirements, mechanical properties and melt viscosity are also an aspect to consider. Viscosity is too high, not easy to shape. [...
