鋼桶表面的除銹

鋼(gang)(gang)桶表(biao)面(mian)在涂裝(zhuang)前容(rong)易被氧(yang)化和腐(fu)蝕(shi)，其表(biao)面(mian)的(de)(de)氧(yang)化皮和鐵(tie)(tie)銹主要是氧(yang)化亞(ya)鐵(tie)(tie)、三(san)(san)氧(yang)化二(er)鐵(tie)(tie)、含(han)水(shui)三(san)(san)氧(yang)化二(er)鐵(tie)(tie)和四(si)氧(yang)化三(san)(san)鐵(tie)(tie)等。在鋼(gang)(gang)桶涂裝(zhuang)前，如果不(bu)將其表(biao)面(mian)的(de)(de)氧(yang)化皮和鐵(tie)(tie)銹除盡，就 會(hui)影響鋼(gang)(gang)桶表(biao)面(mian)漆膜的(de)(de)附著(zhu)力(li)、裝(zhuang)飾性和使用壽命(ming)。因(yin)為鐵(tie)(tie)銹結構疏松，在鋼(gang)(gang)桶表(biao)面(mian)附著(zhu)不(bu)牢，易隨涂層(ceng)一起脫(tuo)落。而氧(yang)化皮在水(shui)汾作用下會(hui)生成(cheng)氫氧(yang)化三(san)(san)鐵(tie)(tie)，體積增大使漆膜起泡(pao)、龜(gui)裂、 脫(tuo)落。漆膜下的(de)(de)氧(yang)化物(wu)與鋼(gang)(gang)桶金屬鐵(tie)(tie)組成(cheng)的(de)(de)腐(fu)蝕(shi)電(dian)池中是陰極，它促(cu)使鋼(gang)(gang)桶表(biao)面(mian)金屬繼續(xu)腐(fu)蝕(shi)，20升(sheng)鋼(gang)(gang)桶，使涂層(ceng)很快被破壞。

閉口鋼桶(tong)可能發生滲漏的因素

１ 桶(tong)(tong)(tong)(tong)腔剪(jian)板料(liao)加(jia)工質(zhi)量(liang) 桶(tong)(tong)(tong)(tong)身(shen)板材剪(jian)切的(de)(de)寬(kuan)(kuan)度(du)(du)和兩端尺(chi)(chi)寸(cun)(cun)的(de)(de)誤(wu)(wu)差(cha)會(hui)(hui)(hui)造(zao)(zao)成(cheng)(cheng)卷焊后錯位，搬(ban)邊(bian)(bian)(bian)(bian)尺(chi)(chi)寸(cun)(cun)寬(kuan)(kuan)窄(zhai)不(bu)(bu)一(yi)，會(hui)(hui)(hui)因為卷邊(bian)(bian)(bian)(bian)層數(shu)達(da)不(bu)(bu)到規定要求，鋼桶(tong)(tong)(tong)(tong)，導致Ｔ型區(qu)的(de)(de)滲漏(lou)。搬(ban)邊(bian)(bian)(bian)(bian)尺(chi)(chi)寸(cun)(cun)過小無(wu)法保證(zheng)卷邊(bian)(bian)(bian)(bian)層數(shu)，過大不(bu)(bu)易(yi)順(shun)利進入底(di)蓋的(de)(de)預(yu)卷邊(bian)(bian)(bian)(bian)內；搬(ban)邊(bian)(bian)(bian)(bian)處由于(yu)碰撞會(hui)(hui)(hui)造(zao)(zao)成(cheng)(cheng)鐵舌(she)的(de)(de)發生。 板材剪(jian)切長度(du)(du)尺(chi)(chi)寸(cun)(cun)誤(wu)(wu)差(cha)、對(dui)角(jiao)(jiao)線的(de)(de)超差(cha)會(hui)(hui)(hui)造(zao)(zao)成(cheng)(cheng)上下(xia)直(zhi)徑(jing)誤(wu)(wu)差(cha)，同時對(dui)角(jiao)(jiao)線超差(cha)會(hui)(hui)(hui)造(zao)(zao)成(cheng)(cheng)縫(feng)焊寬(kuan)(kuan)窄(zhai)不(bu)(bu)一(yi)致，鋼桶(tong)(tong)(tong)(tong)生產廠家，卷合時同樣不(bu)(bu)能保證(zheng)卷邊(bian)(bian)(bian)(bian)層數(shu)以及緊(jin)密(mi)度(du)(du)，閉口鋼桶(tong)(tong)(tong)(tong)，容易(yi)發生滲漏(lou)。 ２ 底(di)蓋沖(chong)壓預(yu)卷邊(bian)(bian)(bian)(bian)質(zhi)量(liang) 底(di)蓋成(cheng)(cheng)型尺(chi)(chi)寸(cun)(cun)對(dui)于(yu)桶(tong)(tong)(tong)(tong)腔搬(ban)邊(bian)(bian)(bian)(bian)尺(chi)(chi)寸(cun)(cun)配合的(de)(de)確定，如果底(di)蓋沖(chong)壓尺(chi)(chi)寸(cun)(cun)和桶(tong)(tong)(tong)(tong)腔搬(ban)邊(bian)(bian)(bian)(bian)尺(chi)(chi)寸(cun)(cun)不(bu)(bu)能保持很好的(de)(de)結(jie)合，會(hui)(hui)(hui)造(zao)(zao)成(cheng)(cheng)卷邊(bian)(bian)(bian)(bian)層數(shu)無(wu)法達(da)到指1定的(de)(de)層數(shu)，容易(yi)造(zao)(zao)成(cheng)(cheng)滲漏(lou)。 ３ 焊接（縫(feng)焊）質(zhi)量(liang) 桶(tong)(tong)(tong)(tong)腔焊接是(shi)制(zhi)桶(tong)(tong)(tong)(tong)工序中的(de)(de)關鍵工序，而焊縫(feng)的(de)(de)兩端的(de)(de)焊接質(zhi)量(liang)是(shi)影響Ｔ型區(qu)是(shi)否滲漏(lou)的(de)(de)關鍵點。 ４ 填料(liao)涂層以及選擇 填料(liao)涂層（密(mi)封(feng)膠）的(de)(de)質(zhi)量(liang)在鋼桶(tong)(tong)(tong)(tong)防滲漏(lou)方面至關重要。按照等(deng)強(qiang)度(du)(du)設(she)計、制(zhi)造(zao)(zao)原理，密(mi)封(feng)質(zhi)量(liang)不(bu)(bu)得(de)低于(yu)鋼桶(tong)(tong)(tong)(tong)其它部位的(de)(de)強(qiang)度(du)(du)。 ５ 封(feng)口輪設(she)計選用以及磨損 封(feng)口輪的(de)(de)設(she)計和磨損程度(du)(du)直(zhi)接影響鋼桶(tong)(tong)(tong)(tong)的(de)(de)卷邊(bian)(bian)(bian)(bian)質(zhi)量(liang)。 ６ 封(feng)桶(tong)(tong)(tong)(tong)機(ji)的(de)(de)性(xing)能和精度(du)(du) 封(feng)桶(tong)(tong)(tong)(tong)機(ji)的(de)(de)同心(xin)度(du)(du)、徑(jing)向跳動(dong)、汽缸(gang)或者液壓缸(gang)推進壓力等(deng)精度(du)(du)的(de)(de)降(jiang)低都會(hui)(hui)(hui)影響封(feng)桶(tong)(tong)(tong)(tong)質(zhi)量(liang)。
