The performance of Liu Fang Zi brand natural sodium bentonite such as water-swelling, water proof, viscosity, plasticity, compaction, stability, lubricity and cation exchange, etc are examined to be in the leading position in Asia. It is renowned as excellent bentonite out of “omnipotent clay” and can compare beauty with American Wyoming bentonite.
“Liu Fang Zi deposit is of or similar to layered structure, parallel output with four industrial layers, including M layer (main layer),the largest one with the best quality, which distributes stably. The ore is ash green with compact and delicate mud or clay-like structure, uniform texture, porcelain or tile shaped fracture, wax luster and strong smooth feel; it turns fragile or powder when dried and tenacious when wet. It swells and disintegrates slowly in water. A stable colloidal suspension is formed after stirring. The main content is montmorillonite, ranging from 50 to 90%. The average content is 70%. Seldom does it contain impure mixture. It has tremendous economic value and big potential for development.”
