Apparatus and method for processing inorganic coating agent

Abstract

The invention provides an apparatus and a method for processing an inorganic coating agent. The apparatus for processing the inorganic coating agent comprises a water glass storage tank, a water glass dilution tank, a desalinized water storage tank, a mixer and a density meter, the water glass dilution tank communicates with the water glass storage tank through a first pipeline, the water glass storage tank is arranged at the inlet end of the first pipeline, and the water glass dilution tank is arranged at the outlet end of the first pipeline; the desalinized water storage tank communicates with the first inlet of the first pipeline; the mixer is arranged on the first pipeline, and is positioned between the first inlet and the water glass dilution tank; and the density meter is arranged on the first pipeline, and is positioned between the mixer and the water glass dilution tank. The apparatus for processing the inorganic coating agent has the advantages of rapid and uniform dilution of water glass, effective reduction of the water use mount, automatic control, high accuracy, simplicity and convenience in operation, low cost, and improvement of the market competitiveness of a product.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a device and method for processing inorganic coating agents. Background technique [0002] Due to the photochemical properties and lattice defects of titanium dioxide base materials, it is necessary to block the photoactive points through inorganic and organic coatings to improve the weather resistance and gloss of titanium dioxide, and to improve its wetting in various media. Sexuality and dispersion. In the inorganic coating, silica-alumina is mainly used as the main reagent coating. The use of silicon coating is mainly through the generation of "active silicon" to form a layer of dense amorphous water and silicon dioxide skin-like film, which precipitates on the surface of titanium dioxide particles, improving the high weather resistance, high dispersion, high Gloss, high whiteness and high wettability. Titanium silica coating generally adopts 10%-15% concentration of Na 2 Si...

AI Technical Summary

Problems solved by technology

If there is no proven method to dilute Na 2 SiO 3 Affect the organic coating of titanium dioxide, affect the weather resistance, dispersibility and other properties of the product, resulting in unstable performance of titanium dioxide

At the same time, it will also affect the cycle of titanium dioxide production and reduce production efficiency.
