Abstract

A disclosed super-smooth thick glaze is composed of frit and a raw material with a mass ratio of (10-30):100. The super-smooth thick glaze is composed of the frit with good high-temperature fluidity and a part of the raw material, so that a glaze surface is capable of rapidly levelling at a high temperature and is good in fusion performance. Through matching of different materials, the glaze surface is small in high-temperature viscosity, and a gas in a glazer layer is facilitated to be exhausted, thereby guaranteeing the smooth effect of the glaze surface and relatively small and less glaze-layer bubbles. Detection results show that a super-smooth thick glazed porcelain tile prepared from the super-smooth thick glaze has less and small bubbles and relatively good glaze-layer transparent feeling because has the bubble quantity in a vision field with a diameter of 1.6 mm is 1-3 and the diameter of the bubbles is in the scope of 0.02-0.06 mm. The super-smooth thick glazed porcelain tile subjected to polishing has the glossiness of 105 DEG -110 DEG higher than 95 DEG -100 DEG which is the glossiness of common fully-glazed porcelain tiles.

Description

technical field [0001] The invention belongs to the technical field of ceramic glaze production, and in particular relates to a super-flat-thick polished glaze and a manufacturing method of super-flat-thick polished glazed porcelain tiles. Background technique [0002] At present, the production process of ordinary full-polished glazed porcelain tiles is to print or pour a layer of transparent full-polished glaze on the surface of the printed antique bricks, and then use elastic modules to polish after entering the kiln for high-temperature firing. The full glaze thickness of this product is relatively thin after firing. In order to meet the polishing needs, the polishing machine modules generally use elastic modules for polishing. Due to the use of elastic modules, it can be observed that the brick surface of this type of product is not smooth under the lamp tube after paving, especially at the junction of bricks and bricks, it is easy to produce a phenomenon similar to "wa...
