Submicron-sized dispersed liquid preparing method

Abstract

A process for preparing a superfine dispersed liquid includes such steps as dissolving a disperser in a liquid carrier, adding matrix, stirring, adding grinding medium, grinding until the diameter of matrix particle is 10-100 microns, and separating out grinding medium.

Description

technical field

[0001] The invention relates to a method for producing an ultrafine dispersion liquid, especially a wet grinding micronization dispersion method suitable for the fields of colorants, organic compounds, metals or metal oxides, and pharmaceutical compounds. Background technique

[0002] Micronization technology is a key technology for manufacturing in many industries. Among them, wet grinding method is a relatively economical process and can be applied to different materials. Wet grinding is a traditional micronization dispersion method, and its micronization technology and products have a wide range of industrial applications. For example, colorant dispersions are widely used in many fields such as paints, inks, pigments, and industrial dyeing. With the improvement of technology, the micronization method of wet grinding can disperse materials to the nanometer scale, such as using different designs of dispersion equipment, different types of dispersion aids, a...
