Studies concerning the improvement in quality of green sand by repeated freezing of bentonite suspensions.

Author(s) : SIMIONESCU G., CONSTANTINESCU A.

Type of article: Article

Summary

A practical method is repeated freezing of the bentonite suspensions, which helped obtain a super-rendering of montmorillonite particles by pounding the particles with additioned or adsorbed water upon the micells. This is a process by which repeatedly frozen water increases its volume and polishes the binder particles, thus leading to an enlarging of the additioning surfaces and micells surfaces.
