Comparison of layer thickness on materials produced by sol-gel transition on substrates removed from aqueous solutions of colloidal binders

Abstract

This paper presents the method of investigating the sol-gel transition by constant speed removal of plates, made of suitable substrate, from an aqueous colloidal binder. The thickness of the deposited colloidal binder layer depends on the particle sizes in the binder. The processing feasibility of colloidal binders reduced by aggregation of particles is difficult to evaluate without access to special measuring equipment. Development of a simple method for prompt evaluation of performance parameters in colloidal binders may have industrial applications.
