噴(pen)(pen)(pen)丸(wan)又分為噴(pen)(pen)(pen)丸(wan)和噴(pen)(pen)(pen)砂。用(yong)(yong)噴(pen)(pen)(pen)丸(wan)進行(xing)表面(mian)處理(li)，打擊(ji)力大，清(qing)(qing)理(li)效果(guo)明顯。但噴(pen)(pen)(pen)丸(wan)對薄板工(gong)(gong)件(jian)(jian)(jian)的(de)(de)處理(li)，容易使工(gong)(gong)件(jian)(jian)(jian)變(bian)形(xing)，且(qie)鋼丸(wan)打擊(ji)到工(gong)(gong)件(jian)(jian)(jian)表面(mian)(無(wu)論拋(pao)(pao)丸(wan)機或噴(pen)(pen)(pen)丸(wan))使金屬基材產生變(bian)形(xing)，由(you)于(yu)(yu)Fe3O4和Fe2O3沒有(you)塑性，破碎后(hou)剝(bo)離，而油膜與(yu)基材一同變(bian)形(xing)，所以對帶有(you)油污的(de)(de)工(gong)(gong)件(jian)(jian)(jian)，拋(pao)(pao)丸(wan)、噴(pen)(pen)(pen)丸(wan)無(wu)法徹(che)底清(qing)(qing)除油污。在現有(you)的(de)(de)工(gong)(gong)件(jian)(jian)(jian)表面(mian)處理(li)方法中(zhong)，清(qing)(qing)理(li)效果(guo)最佳的(de)(de)還數(shu)噴(pen)(pen)(pen)砂清(qing)(qing)理(li)。噴(pen)(pen)(pen)砂適用(yong)(yong)于(yu)(yu)工(gong)(gong)件(jian)(jian)(jian)表面(mian)要求較高的(de)(de)清(qing)(qing)理(li)。但是我(wo)國目前通用(yong)(yong)噴(pen)(pen)(pen)砂設(she)備中(zhong)多由(you)鉸龍、刮(gua)板、斗(dou)式(shi)提(ti)升(sheng)機等(deng)原始笨重輸(shu)砂機械組成。用(yong)(yong)戶(hu)需要施(shi)建(jian)一個深(shen)地坑(keng)及(ji)做(zuo)防水層來裝置機械，建(jian)設(she)費(fei)用(yong)(yong)高，維修(xiu)工(gong)(gong)作量及(ji)維修(xiu)費(fei)用(yong)(yong)極大，噴(pen)(pen)(pen)砂過程中(zhong)產生大量的(de)(de)矽(xi)塵無(wu)法清(qing)(qing)除，嚴重影響操(cao)作工(gong)(gong)人的(de)(de)健康并污染環(huan)境
