The Distribution Of Pigmentation Content And Hair Color Saturation In Ceramic Ink
The solid content in ceramic ink is directly related to the stability of the ink and the saturation of hair color. The author was informed that the current emerging Indian market, many traditional color agents began to turn to the production of ink, ink solid content is also significantly higher than domestic ink, such as yellow ink in the solid content of inotin has been done more than 50%, there are other pigment solid content is also higher than the domestic. It is worth noting that individual enterprises take the hair color depth or hair color saturation of ceramic ink as one of the competitive advantages, which is not desirable. Because the depth of ceramic ink is determined by the hair saturation of the ceramic color material and the solid content in the ink.
At present, the common ceramic color materials are basically diluted, some products dilution even reached 50%. Why do we often say that the export of products on the quality requirements are high? That is because foreign customers are like the original, or low dilution of the product. The conservative dilution of the ceramic glaze industry is 5%. Because the consequences of the original version out is not only a deep question, but also the quality of stability can be maintained as a guarantee of the technical strength of enterprises.
The solid content in the ink is directly related to the combination of solvent and dispersant. The saturation of black, blue and red-brown hair in ceramic color material is very high, as long as the original version is guaranteed, the solid content is very dark in about 20-30% hair color. Of course, for ink pigment, the proportion is also an important issue. In order to avoid the appearance of layering and other noise after grinding, it is not possible to add fillers, therefore, ceramic ink hair color stability is basically by adjusting the solid content of the ink to blend.
The stability of ceramic ink is still a difficult problem in the ink industry, the original hair color of ceramic pigment is related to the late color saturation of the ink and the addition of solid content, solvent and dispersant deployment is only with the ink dispersion and prevention of sedimentation and other properties. In general, color performance is the main factor affecting ink quality.
At present, the domestic ink is relatively extensive, the traditional ceramic color formulation basically after a certain process can be used for the production of ceramic ink, and before the solvent and dispersant no major technological breakthrough, the best way to improve the quality of domestic ceramic ink is to improve the performance of domestic ink by improving the processing process of ceramic color. The introduction of raw materials of ceramic color materials directly affects the conductivity of hair color and later color, especially the addition of mineralizer is relatively unfavorable to the production of ink, but do not add mineralizer and can not be color requirements, so for ceramic color can not use mineralizer, can increase the burn temperature and improve the initial fineness of raw materials, to achieve the effect of reducing the burn temperature and improve reaction activity. More importantly, the process treatment before ceramic ink enters the grinding machine is also very important, and choosing the right pre-dispersion process is also one of the technical means to improve the quality of ceramic ink.
