Bentonite Powder And Lumps

タイトルまたは説明

Bentonite is very fine grained mineral. It vary in color from cream to olive green. Bentonite shows conchoidal or subconchoidal fracture; can be easily cut with knife into thin shavings. It shows waxy luster on freshly cut surface and are soapy to feel. Bentonite is an important naturally occurring clay of great commercial importance. Based on water absorbing qualities in industry, Bentonite are know as swelling and non-swelling types.
The swelling types absorb large quantities of water, swells enormously in the process and remains in suspension for a long time in dilute water dispersions.
The non-swelling absorbs water slightly more than ordinary plastic clays. It does not swell much and settles rapidly in dilute suspensions. There are all gradations between two types. The swelling type is highly colloidal and know as sodium montmorillonite. The swelling property is reversible, i.e. the Bentonite can be dried and re-swelled again and again.
