摘要： An improved slurry blasting process is disclosed wherein a liquid carrier medium such as water contains a dispersed water-soluble particulate abrasive to enhance blast cleaning efficiency and wherein the liquid carrier comprises a saturated solution such as the dissolved particulate abrasive so as to minimize the dissolution of the particulate abrasive therein. Slurry blasting at relatively low pressures below 500 psi and at room temperature provides effective and cost efficient cleaning of substrates. The slurry can be recovered and continuously reused. A recrystallization agent can be added to the slurry to increase abrasive particulate growth in the saturated solution.
