Abstract

The invention relates to a method for preparing aventurine fluoride-free opal glass. The method for preparing aventurine fluoride-free opal glass is characterized by comprising the following steps: 1) carrying out burden calculation on the ingredient contents of oxides so as to obtain a charger sheet, introducing various oxides respectively by using raw mineral materials and raw chemical materials, and weighing and mixing the oxides so as to obtain a glass batch; 2) putting the glass batch obtained in the step 1) into a horseshoe flame glass smelting kiln to carry out smelting, then enabling the obtained product to enter a cooling part, wherein the temperature of the cooling part is controlled between 1300 DEG C and 1350 DEG C; 3) uniformly adding aventurine frits with the particle size of 1-15 mm into the cooling part so as to obtain a glass flow with aventurines; and 4) enabling the glass flow with aventurines obtained in the step 3) to flow to a forming machine arranged at the lower part of the horseshoe flame glass smelting kiln by a feed channel connected with the cooling part of the horseshoe flame glass smelting kiln, thereby obtaining the aventurine fluoride-free opal glass. The aventurine fluoride-free opal glass prepared by using the method disclosed by the invention not only has the characteristics of opal glass, but also has small plate crystals, therefore, the aventurine fluoride-free opal glass is sparkling.

Description

technical field [0001] The invention relates to a preparation method of Jinxing fluorine-free opacified glass. Background technique [0002] The opacified glass mainly includes fluoride opacified glass, phosphate opacified glass, oxide opacified glass, and phase-separated opacified glass. Due to its special optical properties and decorative properties, opal glass is widely used in instrumentation, architectural lighting, medical equipment, arts and crafts decoration, daily utensils, antique white porcelain bottles, art, etc. Compared with transparent glass, opal glass Turbid glass has the characteristics of soft color, high cleanliness and elegance. In recent years, the application of opacity glass has become more and more extensive, and the production scale is also gradually expanding, showing a good market development prospect. [0003] The mechanism of glass opacification mainly includes crystal grain opacification, phase separation opacification, unmelted particle opac...
