閉(bi)口(kou)鋼桶可能發生滲漏的因(yin)素(su)

１ 桶(tong)(tong)(tong)腔剪板(ban)料(liao)(liao)加工(gong)質(zhi)(zhi)(zhi)(zhi)(zhi)量 桶(tong)(tong)(tong)身板(ban)材剪切的(de)(de)(de)(de)寬(kuan)度(du)(du)(du)和兩(liang)端尺(chi)(chi)寸(cun)的(de)(de)(de)(de)誤差(cha)會(hui)造(zao)成(cheng)卷(juan)焊后錯(cuo)位(wei)，搬(ban)邊(bian)(bian)(bian)尺(chi)(chi)寸(cun)寬(kuan)窄不一，會(hui)因為卷(juan)邊(bian)(bian)(bian)層(ceng)數達不到規定要求(qiu)，20升(sheng)閉口鋼(gang)桶(tong)(tong)(tong)，導致(zhi)Ｔ型(xing)區(qu)的(de)(de)(de)(de)滲漏。搬(ban)邊(bian)(bian)(bian)尺(chi)(chi)寸(cun)過(guo)(guo)小無法(fa)保(bao)證卷(juan)邊(bian)(bian)(bian)層(ceng)數，過(guo)(guo)大不易順利進入底蓋(gai)的(de)(de)(de)(de)預(yu)卷(juan)邊(bian)(bian)(bian)內；搬(ban)邊(bian)(bian)(bian)處由于碰撞(zhuang)會(hui)造(zao)成(cheng)鐵舌(she)的(de)(de)(de)(de)發生。 板(ban)材剪切長度(du)(du)(du)尺(chi)(chi)寸(cun)誤差(cha)、對角(jiao)線(xian)的(de)(de)(de)(de)超(chao)差(cha)會(hui)造(zao)成(cheng)上下直(zhi)徑(jing)誤差(cha)，上海20升(sheng)鋼(gang)桶(tong)(tong)(tong)，同(tong)時對角(jiao)線(xian)超(chao)差(cha)會(hui)造(zao)成(cheng)縫焊寬(kuan)窄不一致(zhi)，卷(juan)合(he)時同(tong)樣不能(neng)保(bao)證卷(juan)邊(bian)(bian)(bian)層(ceng)數以(yi)及(ji)緊密(mi)度(du)(du)(du)，容易發生滲漏。 ２ 底蓋(gai)沖壓(ya)預(yu)卷(juan)邊(bian)(bian)(bian)質(zhi)(zhi)(zhi)(zhi)(zhi)量 底蓋(gai)成(cheng)型(xing)尺(chi)(chi)寸(cun)對于桶(tong)(tong)(tong)腔搬(ban)邊(bian)(bian)(bian)尺(chi)(chi)寸(cun)配合(he)的(de)(de)(de)(de)確定，20升(sheng)鋼(gang)桶(tong)(tong)(tong)生產廠(chang)家，如(ru)果底蓋(gai)沖壓(ya)尺(chi)(chi)寸(cun)和桶(tong)(tong)(tong)腔搬(ban)邊(bian)(bian)(bian)尺(chi)(chi)寸(cun)不能(neng)保(bao)持(chi)很好的(de)(de)(de)(de)結合(he)，會(hui)造(zao)成(cheng)卷(juan)邊(bian)(bian)(bian)層(ceng)數無法(fa)達到指1定的(de)(de)(de)(de)層(ceng)數，容易造(zao)成(cheng)滲漏。 ３ 焊接（縫焊）質(zhi)(zhi)(zhi)(zhi)(zhi)量 桶(tong)(tong)(tong)腔焊接是制桶(tong)(tong)(tong)工(gong)序(xu)中的(de)(de)(de)(de)關鍵工(gong)序(xu)，而焊縫的(de)(de)(de)(de)兩(liang)端的(de)(de)(de)(de)焊接質(zhi)(zhi)(zhi)(zhi)(zhi)量是影響Ｔ型(xing)區(qu)是否滲漏的(de)(de)(de)(de)關鍵點。 ４ 填料(liao)(liao)涂層(ceng)以(yi)及(ji)選(xuan)擇 填料(liao)(liao)涂層(ceng)（密(mi)封(feng)膠）的(de)(de)(de)(de)質(zhi)(zhi)(zhi)(zhi)(zhi)量在鋼(gang)桶(tong)(tong)(tong)防滲漏方(fang)面至關重要。按照等強度(du)(du)(du)設計、制造(zao)原理，密(mi)封(feng)質(zhi)(zhi)(zhi)(zhi)(zhi)量不得低于鋼(gang)桶(tong)(tong)(tong)其它部(bu)位(wei)的(de)(de)(de)(de)強度(du)(du)(du)。 ５ 封(feng)口輪(lun)設計選(xuan)用以(yi)及(ji)磨損 封(feng)口輪(lun)的(de)(de)(de)(de)設計和磨損程度(du)(du)(du)直(zhi)接影響鋼(gang)桶(tong)(tong)(tong)的(de)(de)(de)(de)卷(juan)邊(bian)(bian)(bian)質(zhi)(zhi)(zhi)(zhi)(zhi)量。 ６ 封(feng)桶(tong)(tong)(tong)機(ji)的(de)(de)(de)(de)性能(neng)和精度(du)(du)(du) 封(feng)桶(tong)(tong)(tong)機(ji)的(de)(de)(de)(de)同(tong)心度(du)(du)(du)、徑(jing)向跳動(dong)、汽缸或者液壓(ya)缸推進壓(ya)力(li)等精度(du)(du)(du)的(de)(de)(de)(de)降低都(dou)會(hui)影響封(feng)桶(tong)(tong)(tong)質(zhi)(zhi)(zhi)(zhi)(zhi)量。

鋼桶表面的除銹方法分為(wei)化學方法和機械法兩大類(lei)。

化(hua)(hua)學(xue)法除銹是利(li)用(yong)化(hua)(hua)學(xue)瓜或電(dian)化(hua)(hua)學(xue)瓜從(cong)鋼(gang)(gang)桶(tong)表(biao)面溶(rong)解(jie)掉(diao)一般(ban)銹跡、氧(yang)化(hua)(hua)皮及(ji)各種(zhong)腐(fu)蝕產物(wu)而不影響鋼(gang)(gang)桶(tong)基體(ti)金(jin)屬(shu)。常用(yong)的化(hua)(hua)學(xue)除銹方法是酸(suan)洗，即利(li)用(yong)有機酸(suan)或無機酸(suan)使鋼(gang)(gang)桶(tong)表(biao)面的氧(yang)化(hua)(hua)物(wu) 和黃(huang)銹從(cong)鋼(gang)(gang)桶(tong)表(biao)面折(zhe)出。

機械(xie)除(chu)銹(xiu)是利用摩(mo)擦、錘(chui)擊、沖刷等(deng)機械(xie)作用力(li)，使磨粒在鋼桶表面除(chu)去(qu)銹(xiu)跡、高溫氧化皮等(deng)污物。鋼桶企業常用的機械(xie)除(chu)銹(xiu) 方法(fa)是手工(gong)打磨才機械(xie)打磨埤(pi)工(gong)除(chu)銹(xiu)是使用簡單(dan)工(gong)具用人力(li)進 行除(chu)銹(xiu)，其方法(fa)簡單(dan)易(yi)行，20升鋼桶供應，但勞動強度(du)大，生產(chan)效率低(di)且除(chu)銹(xiu)質量差，一般只能(neng)除(chu)去(qu)疏松的或較輕(qing)的鐵銹(xiu)。
