Perlite in paint industry


     Paint is consuming as covering cracks, roughness and gaps in internal and external parts of building, and usually is using in high volume. So texturing of paint has basic role and perlite as a texturing material, effectively is replacing granulated san.

The method of removing paint pollutions from effluent of paint industry is one of the problems of this industry, and workers of dyeing industry are looking for solutions to reducing negative effects on environmental.

In some researches, for removing paint by perlite, from blue ultramarine soluble paint that is one of water based paints, results show this mineral has high ability to absorb paint from paint effluent and in optimal conditions (PH=2, grain size=0/025 mm, particles amount=0/8 gr and contact time=5 minutes) has ability to absorb the most of paint from paint effluent (blue ultramarine).
