Sodium Bentonite

[use]
1. In mechanical casting industry, may use as the casting molding sand, \the cementing agent, may overcome the casting " smuggles the sand " "the skin" phenomenon, reduces the casting waste product rate, guarantees the casting the precision and the smooth finish.

2. In paper industry, use as the paper fillers, strengthens the paper brightness.

3. Using this product strong bonding property, may uses in the white emulsion\the floor rubber\the starch and so on manufacture.

4. Because it has stable suspend property\Increase dense property, can effective respite floating scattered powder, may use as Increase dense\anti-deposition additives of water coating.

5. While, using its excellent dispersion and expansion property, high making pulp rate\Low loss water and colloid property\shear-dilution ability, may use as the drilling mud sodium bentonite.
