時間:2022-06-07點擊次數:1180

1)噴丸(wan)和(he)噴砂(sha)的(de)區別
噴(pen)丸(wan)和(he)噴(pen)砂(sha)的(de)(de)原(yuan)理(li),都是利用空氣(qi)為動力對產(chan)品表面清(qing)理(li)的(de)(de)一(yi)種方式(shi),噴(pen)丸(wan)使(shi)(shi)用的(de)(de)是一(yi)種金(jin)屬磨料,比如(ru):鋼丸(wan)、鋼砂(sha)、陶瓷丸(wan)。噴(pen)砂(sha)使(shi)(shi)用的(de)(de)是非金(jin)屬磨料,比如(ru):剛玉砂(sha)、玻璃(li)砂(sha)、樹脂砂(sha)等。
2)噴(pen)丸和噴(pen)砂的工藝
噴(pen)丸和噴(pen)砂(sha)(sha)的(de)工(gong)藝是(shi)要(yao)根據產品(pin)不(bu)同,性(xing)能(neng)等不(bu)同要(yao)求,才能(neng)確定是(shi)否(fou)使用(yong)噴(pen)丸或者噴(pen)砂(sha)(sha)。
3)噴丸和噴砂設備選型
噴丸和(he)噴砂除了磨料(liao),磨料(liao)的(de)(de)回收(shou)方式,磨料(liao)的(de)(de)分選(xuan)裝置不同以外,其(qi)它設(she)備裝置都一樣,當(dang)(dang)然(ran)(ran)比較小顆粒的(de)(de)磨料(liao)也可(ke)以和(he)噴砂的(de)(de)設(she)備通用,當(dang)(dang)然(ran)(ran)要看實際情況(kuang)而定。
4)噴(pen)(pen)丸(wan)(wan)(wan)(wan)(wan)(wan)是(shi)以(yi)金屬(shu)彈丸(wan)(wan)(wan)(wan)(wan)(wan),利用(yong)壓縮空氣或機(ji)械離心力為(wei)動力和(he)摩(mo)擦力來除去(qu)金屬(shu)銹蝕的(de)方(fang)法。彈丸(wan)(wan)(wan)(wan)(wan)(wan)直(zhi)徑在(zai)0.2-2.5mm之間,壓縮空氣壓力為(wei)0.2-0.6Mpa,噴(pen)(pen)流與表面(mian)(mian)角度(du)為(wei)30度(du)-90度(du)左(zuo)右(you)。噴(pen)(pen)嘴(zui)系用(yong)T7或T8工(gong)(gong)具鋼制成(cheng)并淬(cui)火至硬度(du)50-55HRC,每(mei)個噴(pen)(pen)嘴(zui)使(shi)用(yong)期限為(wei)15-20天。噴(pen)(pen)丸(wan)(wan)(wan)(wan)(wan)(wan)是(shi)用(yong)來清(qing)除厚(hou)度(du)不小于2mm的(de)或不要求保持(chi)準確尺寸(cun)及(ji)輪(lun)廓的(de)中型(xing)(xing)、大型(xing)(xing)金屬(shu)制品以(yi)及(ji)鑄鍛件上(shang)的(de)氧化皮、鐵銹、型(xing)(xing)砂及(ji)舊漆膜(mo)。是(shi)表面(mian)(mian)涂(tu)(鍍)覆前的(de)一種清(qing)理(li)方(fang)法。廣泛用(yong)于大型(xing)(xing)造(zao)船(chuan)廠(chang)、重型(xing)(xing)機(ji)械廠(chang)、汽車廠(chang)等。用(yong)噴(pen)(pen)丸(wan)(wan)(wan)(wan)(wan)(wan)進行表面(mian)(mian)處理(li),打(da)擊力大,清(qing)理(li)效果明顯(xian)。但噴(pen)(pen)丸(wan)(wan)(wan)(wan)(wan)(wan)對(dui)薄(bo)板工(gong)(gong)件的(de)處理(li),容易使(shi)工(gong)(gong)件變(bian)(bian)形(xing)(xing),且(qie)鋼丸(wan)(wan)(wan)(wan)(wan)(wan)打(da)擊到工(gong)(gong)件表面(mian)(mian)(無論(lun)拋丸(wan)(wan)(wan)(wan)(wan)(wan)或噴(pen)(pen)丸(wan)(wan)(wan)(wan)(wan)(wan))使(shi)金屬(shu)基(ji)材產生變(bian)(bian)形(xing)(xing),由(you)于Fe3O4和(he)Fe2O3沒有塑性,破(po)碎后剝離,而油(you)(you)膜(mo)與基(ji)材一同變(bian)(bian)形(xing)(xing),所(suo)以(yi)對(dui)帶有油(you)(you)污(wu)的(de)工(gong)(gong)件,拋丸(wan)(wan)(wan)(wan)(wan)(wan)、噴(pen)(pen)丸(wan)(wan)(wan)(wan)(wan)(wan)無法徹底清(qing)除油(you)(you)污(wu)。
5)噴(pen)(pen)(pen)砂(sha)也是(shi)一(yi)種(zhong)機(ji)械(xie)清(qing)(qing)理方法(fa)(fa),但(dan)噴(pen)(pen)(pen)砂(sha)不是(shi)噴(pen)(pen)(pen)丸(wan),噴(pen)(pen)(pen)砂(sha)用(yong)(yong)的(de)是(shi)砂(sha)粒如(ru)石英砂(sha),噴(pen)(pen)(pen)丸(wan)用(yong)(yong)的(de)是(shi)金屬彈丸(wan)。在現(xian)有的(de)工件表面處理方法(fa)(fa)中,清(qing)(qing)理效果的(de)還數噴(pen)(pen)(pen)砂(sha)清(qing)(qing)理。噴(pen)(pen)(pen)砂(sha)適用(yong)(yong)于(yu)工件表面要求(qiu)較高(gao)的(de)清(qing)(qing)理。但(dan)是(shi)我國目前通用(yong)(yong)噴(pen)(pen)(pen)砂(sha)設(she)備中多由鉸龍、刮板、斗式提(ti)升機(ji)等原始笨重輸砂(sha)機(ji)械(xie)組成。用(yong)(yong)戶需要施建(jian)一(yi)個深地坑及(ji)做防(fang)水層來(lai)裝置機(ji)械(xie),建(jian)設(she)費用(yong)(yong)高(gao),維(wei)修工作量及(ji)維(wei)修費用(yong)(yong)極大(da)。隨著國家對環境(jing)保護和(he)工業衛生的(de)重視,由于(yu)噴(pen)(pen)(pen)砂(sha)過(guo)程有大(da)量粉塵(chen)產生不僅(jin)嚴重污染環境(jing),還及(ji)易導(dao)致操作者的(de)職業病(bing)(矽肺),已大(da)量將噴(pen)(pen)(pen)丸(wan)來(lai)代替噴(pen)(pen)(pen)砂(sha)。
