Experimental Study on Paint Removal From Aluminum Surface Using Ice Jet
摘要
Abstract
Icejet(blasting)technologyshowsapromisingprospectofapplicationandextensioninsurfacecleaningandde-painting engineering because of its environmentally friendly feature.The main objective of this work is to present a deeply experi-mental study on the organic paint removal from aluminum alloy(2A12)substrates and the surface damage development by ice jets. The effects of ice blasting pressure and blasting time on de-painting and damage to the substrate were mainly concerned.It was shown that at blasting pressure of 0.2MPa,organic paint coatings can be stripped from the 2A12 substrates.The paint coatings, moreover,are removed more effectively with increasing blasting pressure.Little changes of the roughness of the blasted substrate surface can be observed.SEMimages showed little plastic deformation at the blasting pressure of 0.5MPa existed on the surface. Whereas,a few of impact craters due to impact of high-velocity ice particles appeared at 0.7MPa for 7s of exposure time with its number increasing obviously for 15s.关键词
