Natrificated Bentonite - dried
Natrificated bentonite is selectively
excavated rock,homogenised and dried by indirect heat.The natrium
sodium is added to natural bentonite in kneading machine to improve the
qualities of natural bentonite.The whole technology is closely checked
and maintaned by computers.
Natrificated bentonite-dried-is well defined by its:
- Increased sorbitive ability
- Increased plasticity
- Increased binding
- Increased strength in condensing area
Use:
Semi-product used for preparation of
bentonite containing products for building industry - concrete
injections, timbering slurry, drilling slush, smelting, food and
pharmacy, ore dump preparation.
