Embodiment 1

[0034] The production process of the ceramics with digital control glazing comprises the following steps:

[0035] A. The ceramic powder is conveyed by the conveyor belt into the press hopper, and the press is made into a ceramic green body under a pressure of 25MPa;

[0036] B. Transport the shaped body to a multi-layer horizontal drying kiln, and dry it in an air atmosphere of 160°C for 50 minutes;

[0037] C. Add the digital surface glaze with a viscosity of 18mPa·s at 40°C, the glaze required for printing patterns, protective glaze, etc. to the ceramic digital printer, and set the glaze amount of the digital surface glaze in the ceramic digital printer to 120g / m 2 , the pattern to be printed, and the glaze amount of the protective glaze is 40 g / m 2 , sending the dried green body into the ceramic digital printer to print the digital surface glaze, pattern and protective glaze directly on the green body in sequence;

[0038] D. The green body after glazing is sent into the...

Abstract

The invention discloses a production technology of ceramic with digital-controlled glazing. The production technology comprises the following steps of after a green body subjected to press forming isdried, surface glazes, patterns, various decorative and protective glazes and the like on the green body are directly printed by a digital printer. The technology can realize simultaneous printing ofthe surface glazes and the protective glazes with different effects on a same ceramic tile, can also perform whole glazing or local glazing to the ceramic tile and can also perform simultaneous printing of various colors, and then high-temperature firing is performed; digital printing glazing is accurate in positioning, the patterns are high in simulation degree, high in definition, strong in stereoscopic sensation and little in glazing amount, so that the production technology reduces waste of glazes, saves the energy, reduces emission, accords with the requirements for environmental protection, avoids the defects of cracking, deformation, glazed pinhole and the like of the green body caused by too much glazing quantity and moisture in the glazes, increases the high-grade rate of productsfrom a kiln, is particularly suitable for production of thin plates in a large specification, is high in production intelligence degree and reduces the manpower cost.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a production process of digitally controlled glazed ceramics. Background technique [0002] At present, the glazing process in the production process of traditional ceramics is generally realized by spraying glaze, pouring glaze and printing glazing. to the surface of the body; glazing is to pump the glaze slurry into the high-level tank, and through the control of pipes and valves, the glaze slurry will pass through a smooth bell jar and cover the surface of the body evenly like a waterfall; printing and glazing is through silk screen or rubber rollers to print the glaze on the body; however, the amount of glaze applied by these three methods is relatively large, and only the entire surface can be glazed, which is prone to uneven glaze application, unevenness, lack of glaze, split ends, etc. Process problems lead to production fluctuations; more moisture in the glaze...
