Abstract

A process for preparing nano Kaolinite includes adding the chemical assistant (potassium acetate, dimethyl sulfoxide, thiourea, urea, hydrazine, or their derivative) which can decrease the Coulomb force between layers of kaolinite, heating or plasma, ultrasonic or microwave acting for physiochemical reaction, grinding, water washing and drying.

Description

Technical field:

[0001] The invention relates to a pulverization and separation method. Background technique:

[0002] Kaolin is a 1:1 layered aluminosilicate mineral, which is one of the main raw materials for the production of ceramics. The existing method of pulverizing ceramic raw materials such as kaolin is the grinding method, that is, through physical grinding, the ceramic raw materials such as kaolin are ground into very fine powders, but limited by the existing technology, it is impossible to grind kaolin between layers. The Coulomb force destroys, so the particle size of the ground particles is far from nanometer. Invention content:

[0003] The invention object of the present invention is to provide a kind of preparation method of the nano kaolin that can pulverize the ceramic raw materials such as kaolin to nanometer powder.

[0004] It is mainly to mix chemical additives that can destroy or weaken the Coulomb force between kaolin layers into kaolin. The chem...
