1.拋(pao)丸(wan)(wan)機(ji)機(ji)械(xie)處(chu)理(li)法(fa)：主(zhu)要包括(kuo)拋(pao)丸(wan)(wan)法(fa)和噴丸(wan)(wan)法(fa)。拋(pao)丸(wan)(wan)法(fa)清(qing)(qing)理(li)是利用離心(xin)力將彈丸(wan)(wan)加速，拋(pao)射至工(gong)(gong)件(jian)進(jin)行除銹清(qing)(qing)理(li)的(de)方法(fa)。但拋(pao)丸(wan)(wan)靈活性差，受場(chang)地限制，清(qing)(qing)理(li)工(gong)(gong)件(jian)時有些盲目性，在工(gong)(gong)件(jian)內表面易產生清(qing)(qing)理(li)不到的(de)死角。設備結構復雜(za)，易損件(jian)多，特別(bie)是葉片等零(ling)件(jian)磨損快，維修工(gong)(gong)時多，費用高，一次性投入(ru)大(da)。

2.噴(pen)丸(wan)又分為噴(pen)丸(wan)和噴(pen)砂(sha)。用噴(pen)丸(wan)進行(xing)表面(mian)處(chu)理(li)(li)，打擊力大(da)，清(qing)理(li)(li)效(xiao)(xiao)果(guo)(guo)明顯。但(dan)噴(pen)丸(wan)對薄板工(gong)件(jian)(jian)的(de)處(chu)理(li)(li)，容易使(shi)工(gong)件(jian)(jian)變(bian)(bian)形，且鋼(gang)丸(wan)打擊到工(gong)件(jian)(jian)表面(mian)(無(wu)論拋丸(wan)機(ji)(ji)或(huo)噴(pen)丸(wan))使(shi)金屬基(ji)材產生(sheng)變(bian)(bian)形，由于Fe3O4和Fe2O3沒有塑(su)性(xing)，破碎后剝(bo)離，而油(you)(you)膜與基(ji)材一同變(bian)(bian)形，所以(yi)對帶有油(you)(you)污(wu)的(de)工(gong)件(jian)(jian)，拋丸(wan)、噴(pen)丸(wan)無(wu)法徹底清(qing)除油(you)(you)污(wu)。在現有的(de)工(gong)件(jian)(jian)表面(mian)處(chu)理(li)(li)方法中(zhong)，清(qing)理(li)(li)效(xiao)(xiao)果(guo)(guo)佳的(de)還數噴(pen)砂(sha)清(qing)理(li)(li)。噴(pen)砂(sha)適用于工(gong)件(jian)(jian)表面(mian)要求較高的(de)清(qing)理(li)(li)。但(dan)是我國目前通用噴(pen)砂(sha)設備(bei)中(zhong)多由鉸龍、刮(gua)板、斗式(shi)提升機(ji)(ji)等原始笨(ben)重輸(shu)砂(sha)機(ji)(ji)械組成(cheng)。用戶需(xu)要施建一個深地坑及(ji)做防(fang)水層來裝置機(ji)(ji)械，建設費用高，維修(xiu)(xiu)工(gong)作(zuo)量(liang)及(ji)維修(xiu)(xiu)費用大(da)，噴(pen)砂(sha)過程中(zhong)產生(sheng)大(da)量(liang)的(de)矽塵無(wu)法清(qing)除，嚴重影響(xiang)操作(zuo)工(gong)人的(de)健康(kang)并(bing)污(wu)染環境。
