1.拋(pao)(pao)(pao)丸(wan)(wan)(wan)(wan)機機械(xie)處(chu)理(li)法：主要包(bao)括拋(pao)(pao)(pao)丸(wan)(wan)(wan)(wan)法和噴丸(wan)(wan)(wan)(wan)法。拋(pao)(pao)(pao)丸(wan)(wan)(wan)(wan)法清(qing)理(li)是利(li)用離心力將(jiang)彈丸(wan)(wan)(wan)(wan)加速，拋(pao)(pao)(pao)射至工(gong)件(jian)進(jin)行除(chu)銹清(qing)理(li)的方法。但拋(pao)(pao)(pao)丸(wan)(wan)(wan)(wan)靈活性(xing)差(cha)，受場地限(xian)制，清(qing)理(li)工(gong)件(jian)時(shi)有些(xie)盲目性(xing)，在工(gong)件(jian)內(nei)表面(mian)易產生清(qing)理(li)不到的死角(jiao)。設備結構復雜，易損件(jian)多，特別(bie)是葉(xie)片等零件(jian)磨(mo)損快，維修工(gong)時(shi)多，費用高(gao)，一次性(xing)投入(ru)大。

2.噴(pen)(pen)丸(wan)(wan)(wan)又分為噴(pen)(pen)丸(wan)(wan)(wan)和(he)噴(pen)(pen)砂(sha)。用(yong)噴(pen)(pen)丸(wan)(wan)(wan)進行表面處理(li)，打擊力(li)大，清(qing)理(li)效(xiao)(xiao)果(guo)明顯。但噴(pen)(pen)丸(wan)(wan)(wan)對(dui)薄板(ban)工(gong)件(jian)(jian)(jian)的(de)(de)處理(li)，容易使工(gong)件(jian)(jian)(jian)變(bian)(bian)形，且鋼丸(wan)(wan)(wan)打擊到工(gong)件(jian)(jian)(jian)表面(無(wu)論拋丸(wan)(wan)(wan)機(ji)(ji)或噴(pen)(pen)丸(wan)(wan)(wan))使金屬基(ji)材產生(sheng)(sheng)變(bian)(bian)形，由于Fe3O4和(he)Fe2O3沒有塑性，破碎(sui)后剝離，而油膜與(yu)基(ji)材一同變(bian)(bian)形，所以(yi)對(dui)帶有油污(wu)(wu)的(de)(de)工(gong)件(jian)(jian)(jian)，拋丸(wan)(wan)(wan)、噴(pen)(pen)丸(wan)(wan)(wan)無(wu)法(fa)(fa)徹底清(qing)除(chu)油污(wu)(wu)。在現有的(de)(de)工(gong)件(jian)(jian)(jian)表面處理(li)方(fang)法(fa)(fa)中，清(qing)理(li)效(xiao)(xiao)果(guo)佳的(de)(de)還數噴(pen)(pen)砂(sha)清(qing)理(li)。噴(pen)(pen)砂(sha)適用(yong)于工(gong)件(jian)(jian)(jian)表面要求較高(gao)的(de)(de)清(qing)理(li)。但是我(wo)國目前通用(yong)噴(pen)(pen)砂(sha)設備中多由鉸龍(long)、刮板(ban)、斗式提升機(ji)(ji)等原始笨重輸砂(sha)機(ji)(ji)械組成(cheng)。用(yong)戶需要施建(jian)一個深地坑及做防水層(ceng)來裝置(zhi)機(ji)(ji)械，建(jian)設費(fei)用(yong)高(gao)，維修(xiu)工(gong)作量及維修(xiu)費(fei)用(yong)大，噴(pen)(pen)砂(sha)過程(cheng)中產生(sheng)(sheng)大量的(de)(de)矽(xi)塵無(wu)法(fa)(fa)清(qing)除(chu)，嚴重影響操作工(gong)人的(de)(de)健康并污(wu)(wu)染環境。
