Ultrathin slurry sprinkling and glazing process

Abstract

The invention relates to an ultrathin slurry sprinkling and glazing process. The ultrathin slurry sprinkling and glazing process comprises the following steps: preparing a porcelain tile bottom blankfor subsequent use; preparing a face slurry for subsequent use; first-time drying: conveying the bottom blanks in a drying kiln at the temperature of 120-220 DEG C in a period of 60-100 minutes; second-time face slurry sprinkling and applying: carrying out second-time sprinkling and applying, sprinkling 16-22 g / m<2> water on the surfaces of the dried bottom blanks to arrive at a first-time slurrysprinkling position, carrying out waterfall type face slurry sprinkling and applying according to the use amount of 320-450 g / m<2>, and arriving at a second-time slurry sprinkling position about 10-20seconds of transmitting time later; second-time drying: conveying the blanks with the face slurry into the drying kiln at the temperature of 120-220 DEG C again in a drying period of 35-45 minutes; 3D full-color high-definition printing: spraying permeation ink and a permeation aid which are used for preparing digital patterns on the surfaces of the blanks with the dried face slurry layer according to a design file by a 3D full-color high-definition printing machine; firing: firing the blanks in a kiln of which the highest temperature reaches 1160-1220 DEG C in the period of 60-80 minutes; and cooling and polishing to obtain back-to-ancients finished bricks.

Description

technical field [0001] The invention relates to the field of building bricks, in particular to an ultra-thin slurry glazing process. Background technique [0002] Retro bricks have been developed in the Chinese market for several years. Taiwanese businessmen first brought this term into mainland China, and retro brick companies sprung up like mushrooms after rain. In the context of fierce competition in the market, ceramic enterprises and technicians, in addition to innovating in product design, pay more attention to product texture, surface hardness and surface flatness, and strive to reduce production costs. The color and appearance of retro bricks emphatically reflect the style of returning to nature, with rustic, rustic, and rough characteristics. The glazed surface is mostly matte. According to the development trend of globalization, its innovative design and innovative technology endow retro tiles with higher market value and vitality, requiring certain wear-resistant...

[0004] However, the ceramic tiles in the prior art have low wear resistance, poor antifouling ability, and high gloss, which is easy to cause environmental pollution. At present, the inkjet patterns of domestic enterprises are relatively rough and not fine enough. Therefore, the patterns made To be more refined and to win the favor of customers has always been the direction that enterprises strive for
