The high-pressure grinding machine and superfine grinding machine produced by Zenith company are widely used in the field of kaolin grinding and milling. Kaolin is widely used as filler in the paper industry. In recent years, due to the development and application of kaolin in the coating industry, many enterprises have begun to have an extraordinary value.
Because of its high whiteness, soft texture, easy dispersion in water, good acid melting resistance and fire resistance, kaolin has become an indispensable mineral raw material in the coating industry. For example, in the paint industry instead of white pigment titanium dioxide, and through Zenith mills processing kaolin powder with different particle size, it can be applied in different types of paint.
We will analyze the application of kaolin with different particle size. The coarse powder processed by common Raymond mill can be used in dull gloss or flat paint, while the fine powder processed by micro powder grinding can be used to produce high gloss paint or latex pigment, which can make the coating have better opacity, corrosion resistance and anti sedimentation, improve the film hardness and modification The quality of the film.
Calcined kaolin not only has the characteristics of ordinary kaolin, but also has the advantages of irregular shape, excellent optical properties, high oil absorptivity and pigment volume concentration, not easy to aging, wear-resistant, easy to emulsify in water or oil medium, and high covering power. It is widely used in paint and coating industry. Zenith mining machinery provides not only kaolin mill, but also kaolin calcination rotary kiln.
When calcined kaolin is added into the coating, it can shield the ultraviolet radiation, improve the weatherability of the coating, delay the powdering and discoloration, enhance the comprehensive mechanical properties, anti fouling and self-cleaning, acid, alkali and high temperature resistance of the coating, and improve the heat resistance and corrosion resistance of the coating. Paint and coating is a large consumption area of calcined kaolin in China, accounting for 65% ~ 85% of the total consumption. Calcined kaolin with whiteness over 90 and particle size over 1250 mesh is widely used in special functional coatings such as interior and exterior wall coatings, anti-corrosion coatings, powder coatings, heat-resistant coatings, insulation coatings, road marking coatings, waterproof coatings, radiation protection coatings, etc.
