Novel process of one-time fired underglaze color polished crystal tile

Abstract

The invention relates to a novel process of a one-time fired underglaze color polished crystal tile, and belongs to the field of ceramic production processes. The novel process is characterized by carrying out pulverizing, compacting, drying, glazing, printing, frit spreading, firing, polishing and trimming, anti-dirty treatment and packaging on raw materials to obtain a one-time fired underglaze color polished crystal tile. Through regulating the formula of a frit, the mesh number proportion of particles of the frit is improved. The raw materials are uniformly dispersed, and the one-time fired underglaze color polished crystal tile can be fired once, and thus the once firing is reduced, the cost of the one-time fired underglaze color polished crystal tile is greatly reduced, the energy consumption is reduced, the once cooling time is reduced, the preparation period of the one-time fired underglaze color polished crystal tile is shortened, the production efficiency is improved, the preparation cost of the once fired underglaze color polished crystal tile is also lowered virtually, and the market competitiveness of the one-time fired underglaze color polished crystal tile is improved.

Description

technical field [0001] The invention relates to a new process for one-time firing of underglaze color polished crystal bricks, which belongs to the field of ceramic production technology. Background technique [0002] At present, most of the underglaze polished crystal bricks are made of a mixture of low-temperature frit and high-temperature frit deposited on the surface of the printed brick that has been fired at a high temperature. Then the product is obtained by low-temperature secondary firing and polishing. [0003] The current secondary firing process is as follows: [0004] Milling—pressing—drying—glazing—printing—firing—cooling—distributing frit—secondary firing—polishing and trimming—antipollution treatment—packaging— finished product. [0005] Such a technological process is two firings, plus one cooling, and the two firings must be heated twice, which wastes a lot of energy, which is obviously inconsistent with the current energy-saving and emission-reduction p...

Problems solved by technology

[0005] Such a technological process is two firings, plus one cooling, and the two firings must be heated twice, which wastes a lot of energy, which is obviously inconsistent with the current energy-saving and emission-reduction policies, and increases the production capacity. The production cost of the product reduces the competitiveness of the product. At the same time, it needs to be cooled during the two firing processes, which prolongs the preparation time of the product, reduces the production efficiency, and is not conducive to the mass production of the product.
