Method for coating titanium dioxide Zr-Al based on sulfate method
A technology of titanium dioxide and sulfuric acid method, which is used in chemical instruments and methods, inorganic pigment treatment, fibrous fillers, etc., can solve the problem that the aluminum oxide film cannot cover the surface of titanium dioxide uniformly, and affects the gloss, hiding power and weather resistance of titanium dioxide. It can reduce the performance of titanium dioxide, reduce the application performance of titanium dioxide, etc., to achieve the effect of stable product index, increase chemical inertness, and reduce free energy.
