Preparation device for high-quality titanium dioxide ceramic paint and method

Abstract

The invention discloses a preparation device and method for high-quality titanium dioxide ceramic paint, which comprises a reaction chamber, a cooling chamber located below the reaction chamber, an impurity removal device connected with the cooling chamber, and a collection box connected with the impurity removal device; the reaction chamber They are respectively connected with the vacuum pump and the cooling water pump. There are several target heads on the reaction chamber, and the impurities are removed by the plasma method to directly generate high-quality rutile titanium dioxide. The preparation device and method of the high-quality titanium dioxide ceramic paint provided by the present invention are scientific and simple in design, directly generate high-quality rutile-type titanium dioxide through the plasma method, and do not need grinding, directly remove impurities, and have high quality.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a preparation device and method for high-quality titanium dioxide ceramic paint. Background technique [0002] The whiteness of titanium dioxide is very important to the coating industry, which not only affects the quality of titanium dioxide itself, but also affects the brightness of the coating. For pigment titanium dioxide, in addition to taking some measures in production to improve the whiteness, the key lies in the removal of impurities, which have a great adverse effect on the whiteness. The more thoroughly the impurities are removed, the higher the whiteness of the product will be. The significance of using it in paint is even greater. [0003] In the production process of titanium dioxide, if the removal of impurities is not complete, when calcined at high temperature, many impurity elements such as iron, vanadium, chromium, cobalt, cadmium, nickel, etc. exist in the state of ox...

AI Technical Summary

Problems solved by technology

[0003] In the production process of titanium dioxide, if the removal of impurities is not complete, when calcined at high temperature, many impurity elements such as iron, vanadium, chromium, cobalt, cadmium, nickel, etc. exist in the state of oxides, and these colored oxides will be It shows various hues, which affects the hue of the entire titanium dioxide and is not pure white, which greatly affects the quality of the product.
