Characterization of “Float Glass” Eroded by Sandblasting

Abstract

In this work, soda-lime glasses of the “Float Glass” type have been characterized before and after sanding. The latter process consists in producing erosion by sandy particles on the surface of the flat glasses. The impact of this erosion on the properties of these glasses was studied. Two types of sand blasting were carried out, one sandblasting machine was used in the first one, while in the second one sandblasting was carried out at the laboratory to assimilate the effect of the sand wind on the vehicle windscreens. Sandblasting has been found to have an enormous influence on the properties of glasses; the density increased, the chemical attack of the glasses in the acid solutions was greater than by bases, the mechanical resistances and the optical transmissions dropped.
