Background
The color master batch titanium dioxide product for plastics needs to be subjected to dry organic surface treatment after wet inorganic surface treatment. The organic surface treatment is to improve the wettability, dispersibility and rheological property of the titanium dioxide particles in various dispersion media by the adsorption or bonding of polar groups of an organic surfactant on the surface of the titanium dioxide particles and by means of electric repulsion and steric hindrance effects.
In the dry organic coating industry, organic coating agents (mainly organic silicone oil) are generally added in a crushing process, and the adding mode mainly has two modes. One is to add organic coating agent into the crushing medium (mainly high temperature and high pressure steam). Its advantage is that the filming agent is uniformly mixed with titanium white particles by fully dispersing the ground medium. The disadvantage is that the coating agent is easily carbonized by high-temperature superheated steam, thereby affecting the coating effect. And secondly, adding a coating agent before the titanium dioxide material enters a pulverizer. The titanium dioxide powder coating agent has the advantages that the coating agent can be fully mixed with titanium dioxide particles, and the coating agent is not required to be conveyed by using a crushing medium.
