Method for improving pores in surfaces of glazed tiles

Abstract

The invention discloses a method for improving pores in the surfaces of glazed tiles. The method comprises the following steps of standing, wherein porous ceramic tiles discharged out of a kiln standand release heat stress completely; polishing and cutting, wherein the surfaces of the porous ceramic tiles are polished and cut, and the polishing and cutting amount is 0.07-0.1 mm; ink dripping, wherein a dripping pipe is adopted for dripping ceramic ink into crevasses and holes in the porous ceramic tiles polished and cut in a titration manner, and the intake amount of the ceramic ink is determined according to the number and the size of the crevasses and the holes in the porous ceramic tiles polished and cut; curing, wherein by means of the manner of pressurizing and heating of a polishingand milling disc, the ceramic ink fills the crevasses and the holes fully, the pressurizing pressure ranges from 1 kg / m2 to 4 kg / m2, and the heating temperature ranges from 40 DEG C to 60 DEG C; andwaxing and polishing, so that finished products of the glazed tiles are obtained. The ceramic ink fills the holes generated due to floating of air bubbles, consistency of pattern colors of the products can be ensured, the yield of the products is increased, and the anti-fouling effect of the products can also be improved.

Description

technical field [0001] The invention relates to the technical field of building ceramic production, in particular to a method for improving capillary pores on the surface of glazed tiles. Background technique [0002] Polished glaze products have to be poured with a layer of low-temperature transparent glaze on the surface to form a glass-phase glaze layer to improve the transparency of the glaze surface. The organic matter in the glaze oxidizes and releases gas. If the gas is not fully exhausted before the glaze is melted, a large number of fine air bubbles float on the glaze layer surface. Wearing through, after waxing, the wax water fills the air bubbles, resulting in the formation of dense white spots on the brick surface, which affects the appearance and quality of the product. Generally, the porosity problem can be solved by adjusting the firing curve of the kiln or increasing the high-temperature viscosity of the glaze, but it is still difficult to avoid unqualified ...

[0002] Polished glaze products have to be poured with a layer of low-temperature transparent glaze on the surface to form a glass-phase glaze layer to improve the transparency of the glaze surface. The organic matter in the glaze oxidizes and releases gas. If the gas is not fully exhausted before the glaze is melted, a large number of fine air bubbles float on the surface of the glaze layer. After the polishing block cuts and polishes the brick surface, the floating bubbles on the brick surface Wear through, after waxing, the wax water fills the air bubbles, resulting in the formation of dense white spots on the brick surface, which affects the appearance and quality of the product

Generally, the porosity problem can be solved by adjusting the firing curve of the kiln or increasing the high-temperature viscosity of the glaze, but it is still difficult to avoid the occurrence of unqualified products

[0003] Patent 200610123726.X discloses a nano antifouling polished tile production process, the inorganic silicon compound liquid nano-material is infiltrated into the unwaxed polished adobe, and then fired to achieve the combination of the two, thereby achieving the antifouling effect, but the nanometer It needs to be introduced multiple times, and each time it needs to be fired once. This kind of process is complicated to operate and high in cost, which is not conducive to wide application
