Requirements For Color Uniformity Of Ceramic Dressing
In the production process of building sanitary ceramic products, the ceramic color materials used in the glaze are all formulated. Many color varieties although they have been the color material professional company's deployment of training, but the enterprise's technical staff should also have a deep understanding of it. In particular, there are many technical factors and some taboos in the mixing and use of pigments. In addition to glazed color decoration, other decorative methods using pigments, such as color glaze, there are many problems such as whether the A and B colors of the pigment can be mixed with each other to form the expected color and tone, these need to be strict and accurate process selection and process technology regulation.
Some ceramic color materials are not easy to meet a large number of repetitive production and use, resulting in each burn-out after the product color glaze color is different or different colors, so that can not guarantee the consistency of enterprise products. At present, the types of color materials found to be difficult to repeat and batch use, such as Victoria Green, Manganese aluminum pink, chromium tin pink, etc. will produce the above phenomenon. The process solution is to introduce a small number of color-sensitive color components into the pigment with light color to solve the above problem. In the blending of color materials, some enterprises use black and white emulsifiers to make gray, the results can not receive very good results, but also far less than the direct use of cobalt-nickel gray magnesium gray pigment color effect is good. Copper oxide pigments are very sensitive to the atmosphere of the flame, in the oxidation flame appears green, and in the reduction flame appears red, the performance is very different, so this pigment and other color materials for color ingestion should also pay attention to the unexpected effects.
In the high temperature burning of construction sanitary ceramic products, ceramic pigments and glazes melt and blend with each other. Therefore, in order to show the color function of pigments, it is necessary to require that the pigment components and glaze components have a high compatibility and adaptability. In fact, the usual glaze is composed of simple glaze, emulsion and other additives. Therefore, the compatibility of glaze and pigment is actually the compatibility of pigments and simple glazes, emulsions and additives. The radon emulsion glaze of the architectural sanitary ceramics is suitable for all radon pigments. Titanium oxide emulsion glaze is suitable for titanium series pigments. Pigments containing tin oxide, such as tin jaundice and chrome tin pink materials, can be used in combination with tin oxide emulsifiers.
In short, modern building sanitary ceramic products color and glaze decoration technology is making continuous progress. It is very important for ceramic production enterprises to grasp the new trend and new technology of the development of ceramic color in the world in a timely manner. Because of the current use of new color materials and glaze technology to improve the value of products and technical content, it seems to have become the international construction hygiene ceramicindustry production of high-grade products of the new fashion.
