The application scope and characteristics of kaolin

Characteristics and advantages of calcined kaolin:

Calcination is a mineral with porous structure and excellent chemical stability.

The porous structure and chemical composition determine that it has good strength and outstanding electrical insulation function, as well as outstanding adsorption ability and oil absorption.

It has excellent miscibility with polymer materials and is often used as an additive in polymers. It has high dispersion, which can make polymer materials have high modulus and improve tear resistance.

Impact strength and wear resistance can also improve electrical insulation function and water flow resistance.

The treatment requires a series of processes including sand removal, grading separation, bleaching, magnetic separation, layering, filtration, drying, calcination, and grinding. It can be divided into hydration level, layering level, calcination level, and appearance level.

Scope of application: Various types of coatings, including latex coatings, powder coatings, oily coatings, and other categories.

Product features: High whiteness, fine particle size, chemical inertness, high coverage ability, ambitious fluidity and suspension, low cost, etc., which can reduce the demand for expensive dyes; In addition to the common characteristics mentioned above, it also has advantages such as irregular shape, excellent optical function, high oil absorption rate and pigment volume concentration, low aging, wear resistance, and easy emulsification in water or oil medium, and has high hiding power. The most important thing is that it can replace expensive titanium dioxide, and when mixed, it can reduce the light flocculation phenomenon caused by the use of titanium dioxide; Especially used in the production of latex like pigments, coatings can have good opacity, anti-corrosion, and anti settling properties, improve film hardness, and improve film quality.
