An example of the extensive processing of kaolin is found in those products intended for the paper industry. The greatest demand for kaolin-based pigments comes from the paper industry, which uses them to coat and fill papers and boards. There are many ways to produce these pigments. One of the methods used is the water washed process.
The bottom line of this review paper is to highlight the current trends in the hydrothermal synthesis of zeolite, attention is paid to the utilization of natural resources and manufacturing wastes as raw materials to synthesize zeolite. Optimum conditions for sustainable hydrothermal synthesis of zeolites from kaolinite natural resources are ...
Jul 07, 2018· Nanocomposites were successfully prepared from kaolinite nanoplatelets, MFC and wood fibers by a continuous paper-making process showing the industrial scalability of these inorganic hybrids. Continuous processing was successful for a composite based on 51 wt% wood fibers and as much as 35 wt% nano-kaolinite and 14 wt% MFC nanocellulose.
