Description
Technical Field
The invention relates to the technical field of ceramic products, in particular to a jun blue glaze, a ceramic product, a preparation method and application thereof.
Background
Along with the improvement of science and technology and living standard, the variety of ceramic decoration products is more and more abundant, and the demands of people on the ceramic products are also more and more abundant. With the gradual increase of young consumer groups, the thought of fashion foresight of young people influences the transformation of sanitary space, the traditional white basin can not completely meet the demands of consumers, and the consumers pay more attention to personalized, attractive and fashionable products to improve the decorative effect.
For sanitary ceramics, the sanitary ceramics mainly comprises single white glaze, a small amount of pigment is adopted to form single-color glaze color, and the colorful effect of the artistic porcelain glaze cannot be realized; the double-layer glaze mainly has the effects of crystallization imitation, single color and no flow mark. The existing sanitary ceramic is fired by a tunnel kiln, the firing range is too narrow, the ceramic glaze effect of the same kiln car is large in difference, the glaze has the problems of pinholes, bubbles and the like, special effects are difficult to realize in kiln atmosphere and firing period, and the problems of glaze pinholes and the like cannot be solved.
The prior art discloses a jun porcelain sky blue glaze and a preparation method thereof, wherein the jun porcelain sky blue glaze is glazed and fired by a glaze material in a separated mode, the operation is complex, and the effect of flow marks cannot be achieved.
Therefore, the new jun glaze ceramic products which are applicable to tunnel kiln, can realize rapid industrialization, clear flow lines and have no pinhole problem are very necessary to be researched.
Disclosure of Invention
The invention mainly aims to provide a jun blue glaze, a ceramic product and a preparation method and application thereof, and aims to provide a jun blue glaze and a ceramic product thereof, which are suitable for tunnel kilns, can realize rapid industrialization, clear flow marks and no pinhole problem, wherein the jun blue glaze is suitable for most tunnel kilns, has consistent glaze effect within 20 ℃ and solves the problem of over-narrow firing range; the glaze cloth can realize the multilayer glaze color flow line effect after being applied to the green body and once sintered, has clear flow line and no pinholes, and can be used for rapid industrialization.
The jun blue glaze comprises a ground glaze and a cover glaze, wherein iron oxide and manganese oxide contained in the ground glaze are used for color development together to generate an antique copper colored glaze surface; titanium oxide and cobalt oxide contained in the overglaze are mixed to present blue-white textures, and the nepheline is utilized to further improve the white flow line color development of the overglaze, so that the blue-white textures are bright and clear; the ground glaze and the overglaze are mutually melted at high temperature, and the high-calcium raw material and the bovine bone powder in the overglaze are utilized to split phases, so that cobalt-titanium opaque crystals are floated on the surface to form glaze color separation, thereby achieving the effects of multi-layer glaze color and clear flow marks; by utilizing the interaction of zinc oxide, glass powder, heavy calcium and wollastonite in the ground glaze, the ground glaze and the ground glaze can well react at high temperature and low temperature, the firing range is improved, the high-temperature fluidity of the ground glaze is improved, and the problem of pinholes is solved; the ceramic product prepared by the jun blue glaze has wider firing range, is suitable for most tunnel kilns, is simple to operate and can be rapidly industrialized; the ceramic product has the advantages of multi-layer glazing effect, clear flow marks, bright glazing and no pinholes.
The high-ratio zinc oxide and iron oxide in the ground glaze can increase the firing range of the ground glaze, and meanwhile, the iron oxide is easy to exhaust and foam at high temperature, so that the condition of mutually fusing two layers of glaze is created; the high-ratio glass powder and zinc oxide in the overglaze make the overglaze in a low-viscosity melt state from 950 ℃ to 1210 ℃, so that the overglaze can be smoothly discharged at high temperature, and is mutually fused in the discharge process to generate a multi-layer glaze effect, the bluish white in the overglaze is generated from the opacifying effect of titanium oxide crystals and the color development of cobalt oxide, and the bovine bone powder is favorable for phase separation when the overglaze is fused, so that the titanium oxide is not easy to be dissolved and covered, and the flow line effect is formed. Therefore, the requirements on the kiln are not high, and the kiln is applicable to most kilns.
In order to achieve the above purpose, the invention provides a jun blue glaze, which comprises a ground glaze and a cover glaze.
