Abstract

A manufacturing method for colored fluorine-free imitation ceramic glaze belongs to the field of advanced glass materials. According to the manufacturing method, a melt jacking blowing method is adopted, and the five-layer colored fluorine-free imitation ceramic glaze is prepared by dip blowing according to the sequence of bright material, white material, bright material, pigment and bright material. The manufacturing method overcomes the defect that the traditional imitation ceramic glass production greatly depends on the initial temperature of glass melt phase-splitting or devitrification and the cooling speed during forming; and meanwhile, the manufacturing method realizes very good opacifying effect under the condition of lower phosphorous content, and the common defects of uneven opacifying degree, stripe and the like are not liable to occur.

Description

Technical field [0001] A manufacturing method of colored fluorine-free porcelain imitation glass belongs to the field of new glass materials. Background technique [0002] Porcelain glaze (also known as opal glass) is a new material widely used in daily utensils, cosmetic packaging, and architectural lighting and decoration. In recent years, the production scale has gradually expanded and it has a good market development prospect. [0003] The reason for the "devitrification" of the enamel glass is that the glass melt spontaneously precipitates a dispersed phase with a large difference in refractive index from the base glass during the cooling process, so that the light entering the glass is strongly scattered rather than transmitted. The appearance of the dispersed phase of the glass melt during the cooling process can be caused by the liquid-liquid separation caused by the immiscibility of one liquid phase in the other liquid phase, or it may be caused by crystallization, micro b...
