Bentonite (CAS 1302-78-9) Usage
Papermaking Bentonite/sodium base bentonite.

According to the color, it can be divided into gray-white, tan and variegated bentonite mines.
According to its nature and industrial use, it can be divided into sodium-based, calcium-based and sodium-calcium-based, calcium-sodium-based bentonite ore.
According to the water-absorbent bentonite, it can be divided into two categories. The first category can absorb a large amount of water and swell greatly after absorbing water. Keep suspended in thin water dispersant. Such clays are mostly used as plasticizers for ceramics. It can increase the drying strength and firing temperature of the porcelain blank and reduce the adsorption. The second type bentonite can only absorb slightly more water than ordinary plastic clay or bleaching clay, the swelling is not significant, and it quickly precipitates in the thin water dispersant. This type of bentonite is widely used as a clarifying clay, used as a decolorizing agent and purifying agent in chemicals, medicine, and food, a carrier for insecticides, a graphite crucible, a regulator and a binder for enamel glaze, and manufacturing Clay products, etc.
