Problems solved by technology

However, this kind of fluoride imitation porcelain glaze has problems such as serious corrosion of refractory materials and environmental pollution, which greatly limits its application range.
So far, there is no fluorine-free imitation porcelain glaze production method that is less dependent on the glass melt phase separation or crystallization initiation temperature and cooling rate during molding, and can overcome defects such as uneven opacity and streaks report

Abstract

The invention discloses a colored fluoride-free ceramic imitation azure stone, and belongs to the field of new materials of glass. The colored fluoride-free ceramic imitation azure stone is characterized by having a laminated structure and is divided into fiver layers from inside to outside, wherein a first layer is a first bright material layer; a second layer is a white material layer; a third layer is a second bright material layer; a fourth layer is a pigment layer; a fifth layer is a third bright material layer; the thickness of the white material layer is 0.7 to 0.95mm; and the thickness of the pigment layer is 0.6 to 0.85mm. According to the ceramic imitation azure stone, the defect of high dependence degree of the conventional ceramic imitation azure stone on the starting temperature of a glass melt in the phase-splitting or crystallizing process and the cooling speed of the temperature melt in the forming process is overcome; and simultaneously, common defects of non-uniform opacification degrees, stripes and the like are overcome through the ceramic imitation azure stone.

Description

technical field [0001] A colored fluorine-free imitation porcelain glaze belongs to the field of new glass materials. Background technique [0002] Porcelain-like glaze (also known as opalescent glass) is a new material widely used in daily utensils, cosmetic packaging, and architectural lighting and decoration. The production scale is gradually expanding, and it has a good market development prospect. [0003] The reason for the "devitrification" of melamine glaze 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 a dispersed phase during cooling of a glass melt can be caused by liquid-liquid phase separation initiated by the immiscibility of one liquid phase in the other, or by crystallization, microbubbles or microscopic particles. caused by cracks. Depending on ...
