噴(pen)(pen)(pen)(pen)丸(wan)(wan)又分為噴(pen)(pen)(pen)(pen)丸(wan)(wan)和(he)噴(pen)(pen)(pen)(pen)砂(sha)。用噴(pen)(pen)(pen)(pen)丸(wan)(wan)進行表面(mian)(mian)處理(li)，打擊力(li)大(da)，清(qing)理(li)效果明(ming)顯。但噴(pen)(pen)(pen)(pen)丸(wan)(wan)對薄板工(gong)(gong)件的處理(li)，容易使(shi)工(gong)(gong)件變形，且鋼丸(wan)(wan)打擊到工(gong)(gong)件表面(mian)(mian)(無論拋丸(wan)(wan)機(ji)或噴(pen)(pen)(pen)(pen)丸(wan)(wan))使(shi)金屬基材產生變形，由于(yu)Fe3O4和(he)Fe2O3沒有塑性，破碎(sui)后剝(bo)離，而油膜與基材一(yi)同變形，所(suo)以(yi)對帶有油污(wu)的工(gong)(gong)件，拋丸(wan)(wan)、噴(pen)(pen)(pen)(pen)丸(wan)(wan)無法徹底清(qing)除油污(wu)。在(zai)現有的工(gong)(gong)件表面(mian)(mian)處理(li)方法中，清(qing)理(li)效果最佳的還數噴(pen)(pen)(pen)(pen)砂(sha)清(qing)理(li)。噴(pen)(pen)(pen)(pen)砂(sha)適(shi)用于(yu)工(gong)(gong)件表面(mian)(mian)要求較(jiao)高(gao)的清(qing)理(li)。但是(shi)我國目前通用噴(pen)(pen)(pen)(pen)砂(sha)設備中多由鉸龍(long)、刮板、斗式提升機(ji)等(deng)原始笨重(zhong)(zhong)輸(shu)砂(sha)機(ji)械組成。用戶需要施建(jian)一(yi)個深地坑(keng)及做防(fang)水層來(lai)裝置機(ji)械，建(jian)設費用高(gao)，維(wei)(wei)修工(gong)(gong)作(zuo)(zuo)量及維(wei)(wei)修費用極大(da)，噴(pen)(pen)(pen)(pen)砂(sha)過程中產生大(da)量的矽塵(chen)無法清(qing)除，嚴重(zhong)(zhong)影響(xiang)操(cao)作(zuo)(zuo)工(gong)(gong)人的健康并污(wu)染(ran)環境
