閉口鋼(gang)桶可能(neng)發生滲漏(lou)的因素

１ 桶腔(qiang)(qiang)(qiang)剪(jian)板(ban)料(liao)加工質(zhi)(zhi)量(liang)(liang) 桶身板(ban)材剪(jian)切的(de)(de)(de)(de)寬(kuan)度(du)(du)(du)(du)和(he)兩端尺(chi)(chi)(chi)寸(cun)的(de)(de)(de)(de)誤(wu)差會(hui)(hui)造成(cheng)(cheng)(cheng)卷(juan)(juan)(juan)焊(han)(han)(han)后錯位(wei)，搬(ban)邊(bian)(bian)(bian)尺(chi)(chi)(chi)寸(cun)寬(kuan)窄不(bu)一(yi)，會(hui)(hui)因為卷(juan)(juan)(juan)邊(bian)(bian)(bian)層(ceng)(ceng)(ceng)(ceng)(ceng)數(shu)達(da)不(bu)到規定(ding)要求，導(dao)致Ｔ型區(qu)(qu)的(de)(de)(de)(de)滲(shen)(shen)漏(lou)(lou)。搬(ban)邊(bian)(bian)(bian)尺(chi)(chi)(chi)寸(cun)過小無法保證卷(juan)(juan)(juan)邊(bian)(bian)(bian)層(ceng)(ceng)(ceng)(ceng)(ceng)數(shu)，過大不(bu)易(yi)(yi)(yi)順利進入底(di)(di)蓋(gai)(gai)的(de)(de)(de)(de)預卷(juan)(juan)(juan)邊(bian)(bian)(bian)內；搬(ban)邊(bian)(bian)(bian)處由于碰撞會(hui)(hui)造成(cheng)(cheng)(cheng)鐵(tie)舌的(de)(de)(de)(de)發(fa)生。 板(ban)材剪(jian)切長度(du)(du)(du)(du)尺(chi)(chi)(chi)寸(cun)誤(wu)差、對(dui)角線的(de)(de)(de)(de)超差會(hui)(hui)造成(cheng)(cheng)(cheng)上下直徑誤(wu)差，同(tong)時(shi)對(dui)角線超差會(hui)(hui)造成(cheng)(cheng)(cheng)縫(feng)焊(han)(han)(han)寬(kuan)窄不(bu)一(yi)致，卷(juan)(juan)(juan)合(he)時(shi)同(tong)樣不(bu)能(neng)保證卷(juan)(juan)(juan)邊(bian)(bian)(bian)層(ceng)(ceng)(ceng)(ceng)(ceng)數(shu)以(yi)及(ji)(ji)緊密度(du)(du)(du)(du)，容(rong)易(yi)(yi)(yi)發(fa)生滲(shen)(shen)漏(lou)(lou)。 ２ 底(di)(di)蓋(gai)(gai)沖壓(ya)預卷(juan)(juan)(juan)邊(bian)(bian)(bian)質(zhi)(zhi)量(liang)(liang) 底(di)(di)蓋(gai)(gai)成(cheng)(cheng)(cheng)型尺(chi)(chi)(chi)寸(cun)對(dui)于桶腔(qiang)(qiang)(qiang)搬(ban)邊(bian)(bian)(bian)尺(chi)(chi)(chi)寸(cun)配合(he)的(de)(de)(de)(de)確(que)定(ding)，如果底(di)(di)蓋(gai)(gai)沖壓(ya)尺(chi)(chi)(chi)寸(cun)和(he)桶腔(qiang)(qiang)(qiang)搬(ban)邊(bian)(bian)(bian)尺(chi)(chi)(chi)寸(cun)不(bu)能(neng)保持很(hen)好的(de)(de)(de)(de)結合(he)，會(hui)(hui)造成(cheng)(cheng)(cheng)卷(juan)(juan)(juan)邊(bian)(bian)(bian)層(ceng)(ceng)(ceng)(ceng)(ceng)數(shu)無法達(da)到指1定(ding)的(de)(de)(de)(de)層(ceng)(ceng)(ceng)(ceng)(ceng)數(shu)，容(rong)易(yi)(yi)(yi)造成(cheng)(cheng)(cheng)滲(shen)(shen)漏(lou)(lou)。 ３ 焊(han)(han)(han)接(jie)（縫(feng)焊(han)(han)(han)）質(zhi)(zhi)量(liang)(liang) 桶腔(qiang)(qiang)(qiang)焊(han)(han)(han)接(jie)是(shi)(shi)制(zhi)桶工序中(zhong)的(de)(de)(de)(de)關鍵(jian)工序，而焊(han)(han)(han)縫(feng)的(de)(de)(de)(de)兩端的(de)(de)(de)(de)焊(han)(han)(han)接(jie)質(zhi)(zhi)量(liang)(liang)是(shi)(shi)影(ying)響Ｔ型區(qu)(qu)是(shi)(shi)否滲(shen)(shen)漏(lou)(lou)的(de)(de)(de)(de)關鍵(jian)點。 ４ 填料(liao)涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)以(yi)及(ji)(ji)選擇 填料(liao)涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)（密封(feng)膠）的(de)(de)(de)(de)質(zhi)(zhi)量(liang)(liang)在鋼桶防滲(shen)(shen)漏(lou)(lou)方面(mian)至關重要。按照(zhao)等強(qiang)度(du)(du)(du)(du)設(she)計、制(zhi)造原(yuan)理，密封(feng)質(zhi)(zhi)量(liang)(liang)不(bu)得低于鋼桶其它部(bu)位(wei)的(de)(de)(de)(de)強(qiang)度(du)(du)(du)(du)。 ５ 封(feng)口輪設(she)計選用(yong)以(yi)及(ji)(ji)磨損 封(feng)口輪的(de)(de)(de)(de)設(she)計和(he)磨損程(cheng)度(du)(du)(du)(du)直接(jie)影(ying)響鋼桶的(de)(de)(de)(de)卷(juan)(juan)(juan)邊(bian)(bian)(bian)質(zhi)(zhi)量(liang)(liang)。 ６ 封(feng)桶機的(de)(de)(de)(de)性(xing)能(neng)和(he)精度(du)(du)(du)(du) 封(feng)桶機的(de)(de)(de)(de)同(tong)心(xin)度(du)(du)(du)(du)、徑向跳(tiao)動(dong)、汽(qi)缸(gang)或(huo)者(zhe)液壓(ya)缸(gang)推進壓(ya)力(li)等精度(du)(du)(du)(du)的(de)(de)(de)(de)降(jiang)低都會(hui)(hui)影(ying)響封(feng)桶質(zhi)(zhi)量(liang)(liang)。

鋼桶卷封過程(cheng)究竟(jing)能(neng)卷多(duo)(duo)少(shao)層？有人(ren)認為越(yue)(yue)多(duo)(duo)越(yue)(yue)多(duo)(duo)，這(zhe)話沒錯！卷邊層數越(yue)(yue)多(duo)(duo)，20升(sheng)鋼桶供應，強度越(yue)(yue)高，密封效果越(yue)(yue)好(hao)。然而(er)是(shi)不是(shi)能(neng)夠(gou)實現(xian)十層、二十層的卷封呢？這(zhe)里我(wo)們且(qie)不說存在一個質量成本 問題，實際上，這(zhe)是(shi)不能(neng)夠(gou)實現(xian)。

（1）鋼桶(tong)(tong)(tong)原(yuan)(yuan)材料的(de)(de)(de)限制 制作鋼桶(tong)(tong)(tong)，要(yao)(yao)求(qiu)材料含(han)碳量要(yao)(yao)低(di)，塑(su)性(xing)(xing)(xing)(xing)要(yao)(yao)好(hao)。因為(wei)(wei)(wei)這樣加工性(xing)(xing)(xing)(xing)能(neng)好(hao)，焊接、沖壓、脹形(xing)都(dou)容易(yi)保證質量。但(dan)是卷(juan)(juan)邊(bian)(bian)就(jiu)不一(yi)樣了，因為(wei)(wei)(wei)卷(juan)(juan)邊(bian)(bian)輥(gun)槽的(de)(de)(de)大小不可(ke)能(neng)隨著卷(juan)(juan)邊(bian)(bian)過程變化，卷(juan)(juan)邊(bian)(bian)力(li)(li)要(yao)(yao)通過 外(wai)圍的(de)(de)(de)材料逐漸傳遞到卷(juan)(juan)邊(bian)(bian)中(zhong)心(xin)去(qu)，才能(neng)把中(zhong)心(xin)卷(juan)(juan)成。而材料的(de)(de)(de)塑(su)性(xing)(xing)(xing)(xing)越好(hao)，力(li)(li)的(de)(de)(de)傳遞就(jiu)越困難。可(ke)以(yi)想象，如果鋼桶(tong)(tong)(tong)的(de)(de)(de)材料采用(yong)彈(dan)簧鋼，像鐘表的(de)(de)(de)法(fa)條一(yi)樣的(de)(de)(de)材料，不要(yao)(yao)說(shuo)卷(juan)(juan)十層，恐(kong)怕就(jiu)是 二十層也很(hen)(hen)容易(yi)，湖州20升鋼桶(tong)(tong)(tong)，因為(wei)(wei)(wei)它彈(dan)性(xing)(xing)(xing)(xing)和剛性(xing)(xing)(xing)(xing)好(hao)，通過外(wai)圍的(de)(de)(de)卷(juan)(juan)封(feng)(feng)(feng)力(li)(li)很(hen)(hen)容易(yi)傳到中(zhong)心(xin)。但(dan)這是不可(ke)能(neng)的(de)(de)(de)，就(jiu)是因為(wei)(wei)(wei)這種材料彈(dan)性(xing)(xing)(xing)(xing)好(hao)，所以(yi)在卷(juan)(juan)封(feng)(feng)(feng)結束后，20升閉(bi)口鋼桶(tong)(tong)(tong)，卷(juan)(juan)封(feng)(feng)(feng)力(li)(li)消失(shi)的(de)(de)(de)情況下，很(hen)(hen)容易(yi)又反(fan)彈(dan)回原(yuan)(yuan)來的(de)(de)(de) 狀態，也就(jiu)是說(shuo)恢復到卷(juan)(juan)封(feng)(feng)(feng)開始的(de)(de)(de)樣子。這樣顯(xian)然(ran)不是我(wo)們需要(yao)(yao)的(de)(de)(de)。所以(yi)，我(wo)們不可(ke)能(neng)選用(yong)高彈(dan)性(xing)(xing)(xing)(xing)的(de)(de)(de)材料。就(jiu)目前全世界(jie)用(yong)來制作鋼桶(tong)(tong)(tong)的(de)(de)(de)材料來看，我(wo)國的(de)(de)(de)材料剛性(xing)(xing)(xing)(xing)z大，所以(yi)質量也較難保 證。而且卷(juan)(juan)邊(bian)(bian)層數(shu)沒有超過七層的(de)(de)(de)。據國外(wai)有關的(de)(de)(de)研究，鋼桶(tong)(tong)(tong)卷(juan)(juan)邊(bian)(bian)層數(shu)不會超過七層，顯(xian)然(ran)卷(juan)(juan)封(feng)(feng)(feng)力(li)(li)傳送(song)不到那么遠。

鋼(gang)(gang)(gang)桶(tong)包裝材(cai)(cai)料(liao)的分類鋼(gang)(gang)(gang)桶(tong)包裝材(cai)(cai)料(liao)主要為鋼(gang)(gang)(gang)材(cai)(cai)，與其它金屬材(cai)(cai)料(liao)相比，鋼(gang)(gang)(gang)材(cai)(cai)來源較(jiao)豐富，能耗和(he)(he)成本也較(jiao)低，至(zhi)今仍占金屬包裝材(cai)(cai)料(liao)的首位，鋼(gang)(gang)(gang)桶(tong)用鋼(gang)(gang)(gang)材(cai)(cai)主要是低碳(tan)(tan)薄鋼(gang)(gang)(gang)板(ban)。低碳(tan)(tan)薄鋼(gang)(gang)(gang)板(ban)具有(you)良好(hao)的塑(su)性和(he)(he)延展性，20升鋼(gang)(gang)(gang)桶(tong)生產廠家，制桶(tong)工(gong)藝(yi)性好(hao)，有(you)優良的綜合防(fang)護性能。鋼(gang)(gang)(gang)材(cai)(cai)z大的缺點(dian)是耐蝕性差，易銹，必須采用表面鍍層和(he)(he)涂料(liao)等方式(shi)才能使(shi)用。。。。。。。。。。。
