Description
Technical Field
The invention is applied to the technical field of building ceramic production, and particularly relates to a method for manufacturing an inkjet brick.
Background
Along with the upsizing and rapiding of the ink-jet technology, the domestic cultural market is continuously developing, the demand for artistic ornaments is increasingly larger, so that the oil painting ink-jet brick is taken as a novel ink-jet brick to enter households, the oil painting ink-jet brick has higher requirements on the color development of glaze, and meanwhile, the smoothness of the glaze of the brick body can be ensured only by spraying the pattern on the glaze of the brick body through ink. The traditional ink-jet process has no specific pattern design, does not need fine spraying, has lower requirements on the precision of the glaze in the production process, and does not need to treat the glaze corrugation. In addition, since the ink jet of the oil painting needs to use more ink in order to improve the saturation, the pattern of the product can be blurred and distorted after the ink jet printing and firing are carried out on the surface glaze of the traditional formula. Therefore, the traditional manufacturing process is adopted to produce the oil painting ink-jet bricks, so that the patterns are corrugated on the glaze, the display of the patterns is affected, meanwhile, the patterns are incomplete to display, the stable and continuous production cannot be realized, and the resource is wasted.

According to the scheme, the overglaze is sprayed for three or more times at intervals, so that the glaze is smoother and more textured. Wherein, 15-20 parts by weight of barium carbonate is added into the overglaze, so that the content of the whole barium element in the overglaze is about 0.3mol, barium feldspar crystals are separated out from the overglaze in the firing process, and the barium feldspar crystals are matt, so that the color development of the oil painting pattern on the overglaze is purer and more stable than the previous matt glaze mainly containing calcium and magnesium, and the ink is not dispersed and blurred in the subsequent firing process. By adjusting K2O, al2O3 and SiO2 in the glaze ingredients, the generation of glaze melt is facilitated to be further promoted, and the coloring agent in the glaze is not easy to agglomerate and settle. Meanwhile, the amounts of quartz and potassium feldspar are increased, so that the expansion coefficient of the base glaze is slightly smaller than that of a green brick, and the defects of air holes, glaze flowing and the like can be avoided. And further, the method effectively solves the problems of high saturation required glaze pattern integrity, smooth surface and no blurring of the pattern in the firing process.
