natural sodium bentonite

high purity;high dispersion fineness; good distensibility of water;large ion change work well in acidic and basic condition

It has high strength of water absorption and has characteristics of non-poison..non contact-corrosion.non-environment pollution.it is mainly used in the product that cant be sealed with oil,such as for the sealing experiment..optical iinstrument and ammunition etc.it also can be used as desiccant of foodstuff. medicament.its price is lower than silicone desiccant and cement desiccant and without environmental pollution.it goes through grinding.puring.drying shaped high temperature treatment with high-pure montmorillonite.and then cooled.
