METHOD OF USING WATER SOLUBLE FOAMED STARCH FOR RECLAIMING PAINT OVERSPRAY PARTICLES

摘要

A method of using water soluble foamed starch for reclaiming paint overspray particles from air includes the steps of passing a stream of air containing paint overspray particles through an air filter assembly (10) having a filtration element (12). The filtration element (12) consists essentially of water soluble foamed starch. The paint overspray particles are collected on the filtration element (12). The filtration element (12) containing the collected paint overspray particles is deposited in a vessel containing water. The filtration element is dissolved in the water and an aqueous solution of starch in water is formed. The paint overspray particles are separated from the aqueous solution of starch dissolved in water.
