閉口(kou)鋼桶可能發(fa)生滲漏的因素(su)

１ 桶(tong)(tong)(tong)腔剪(jian)(jian)板(ban)料(liao)加工(gong)(gong)質(zhi)(zhi)(zhi)(zhi)量(liang)(liang) 桶(tong)(tong)(tong)身板(ban)材(cai)剪(jian)(jian)切的(de)(de)(de)(de)(de)寬度(du)(du)和(he)(he)兩端(duan)尺(chi)(chi)(chi)(chi)寸(cun)(cun)的(de)(de)(de)(de)(de)誤(wu)差會(hui)造(zao)成(cheng)(cheng)卷(juan)焊(han)(han)后(hou)錯位，搬(ban)邊尺(chi)(chi)(chi)(chi)寸(cun)(cun)寬窄(zhai)不(bu)一(yi)(yi)，會(hui)因為卷(juan)邊層(ceng)(ceng)(ceng)數(shu)達(da)不(bu)到(dao)規(gui)定(ding)要求，導致(zhi)Ｔ型(xing)區(qu)的(de)(de)(de)(de)(de)滲(shen)(shen)漏(lou)。搬(ban)邊尺(chi)(chi)(chi)(chi)寸(cun)(cun)過(guo)小無法(fa)保(bao)證(zheng)卷(juan)邊層(ceng)(ceng)(ceng)數(shu)，過(guo)大(da)不(bu)易順利進入底(di)(di)(di)蓋的(de)(de)(de)(de)(de)預卷(juan)邊內；搬(ban)邊處(chu)由于(yu)(yu)(yu)碰撞會(hui)造(zao)成(cheng)(cheng)鐵舌(she)的(de)(de)(de)(de)(de)發(fa)(fa)生。 板(ban)材(cai)剪(jian)(jian)切長(chang)度(du)(du)尺(chi)(chi)(chi)(chi)寸(cun)(cun)誤(wu)差、對(dui)(dui)角(jiao)線的(de)(de)(de)(de)(de)超(chao)差會(hui)造(zao)成(cheng)(cheng)上下直徑誤(wu)差，同時對(dui)(dui)角(jiao)線超(chao)差會(hui)造(zao)成(cheng)(cheng)縫焊(han)(han)寬窄(zhai)不(bu)一(yi)(yi)致(zhi)，卷(juan)合(he)時同樣不(bu)能保(bao)證(zheng)卷(juan)邊層(ceng)(ceng)(ceng)數(shu)以(yi)及緊密(mi)度(du)(du)，容易發(fa)(fa)生滲(shen)(shen)漏(lou)。 ２ 底(di)(di)(di)蓋沖(chong)壓預卷(juan)邊質(zhi)(zhi)(zhi)(zhi)量(liang)(liang) 底(di)(di)(di)蓋成(cheng)(cheng)型(xing)尺(chi)(chi)(chi)(chi)寸(cun)(cun)對(dui)(dui)于(yu)(yu)(yu)桶(tong)(tong)(tong)腔搬(ban)邊尺(chi)(chi)(chi)(chi)寸(cun)(cun)配(pei)合(he)的(de)(de)(de)(de)(de)確定(ding)，如果底(di)(di)(di)蓋沖(chong)壓尺(chi)(chi)(chi)(chi)寸(cun)(cun)和(he)(he)桶(tong)(tong)(tong)腔搬(ban)邊尺(chi)(chi)(chi)(chi)寸(cun)(cun)不(bu)能保(bao)持很好的(de)(de)(de)(de)(de)結合(he)，會(hui)造(zao)成(cheng)(cheng)卷(juan)邊層(ceng)(ceng)(ceng)數(shu)無法(fa)達(da)到(dao)指1定(ding)的(de)(de)(de)(de)(de)層(ceng)(ceng)(ceng)數(shu)，容易造(zao)成(cheng)(cheng)滲(shen)(shen)漏(lou)。 ３ 焊(han)(han)接(jie)（縫焊(han)(han)）質(zhi)(zhi)(zhi)(zhi)量(liang)(liang) 桶(tong)(tong)(tong)腔焊(han)(han)接(jie)是(shi)(shi)制桶(tong)(tong)(tong)工(gong)(gong)序(xu)中(zhong)的(de)(de)(de)(de)(de)關鍵工(gong)(gong)序(xu)，開口鋼(gang)桶(tong)(tong)(tong)廠家，而焊(han)(han)縫的(de)(de)(de)(de)(de)兩端(duan)的(de)(de)(de)(de)(de)焊(han)(han)接(jie)質(zhi)(zhi)(zhi)(zhi)量(liang)(liang)是(shi)(shi)影(ying)響Ｔ型(xing)區(qu)是(shi)(shi)否(fou)滲(shen)(shen)漏(lou)的(de)(de)(de)(de)(de)關鍵點。 ４ 填(tian)料(liao)涂(tu)層(ceng)(ceng)(ceng)以(yi)及選擇 填(tian)料(liao)涂(tu)層(ceng)(ceng)(ceng)（密(mi)封(feng)(feng)(feng)膠）的(de)(de)(de)(de)(de)質(zhi)(zhi)(zhi)(zhi)量(liang)(liang)在鋼(gang)桶(tong)(tong)(tong)防(fang)滲(shen)(shen)漏(lou)方面至關重要。按照(zhao)等(deng)強度(du)(du)設(she)計、制造(zao)原(yuan)理，密(mi)封(feng)(feng)(feng)質(zhi)(zhi)(zhi)(zhi)量(liang)(liang)不(bu)得低于(yu)(yu)(yu)鋼(gang)桶(tong)(tong)(tong)其它部位的(de)(de)(de)(de)(de)強度(du)(du)。 ５ 封(feng)(feng)(feng)口輪設(she)計選用以(yi)及磨損(sun) 封(feng)(feng)(feng)口輪的(de)(de)(de)(de)(de)設(she)計和(he)(he)磨損(sun)程度(du)(du)直接(jie)影(ying)響鋼(gang)桶(tong)(tong)(tong)的(de)(de)(de)(de)(de)卷(juan)邊質(zhi)(zhi)(zhi)(zhi)量(liang)(liang)。 ６ 封(feng)(feng)(feng)桶(tong)(tong)(tong)機的(de)(de)(de)(de)(de)性能和(he)(he)精度(du)(du) 封(feng)(feng)(feng)桶(tong)(tong)(tong)機的(de)(de)(de)(de)(de)同心度(du)(du)、徑向(xiang)跳動、汽缸或者液(ye)壓缸推進壓力等(deng)精度(du)(du)的(de)(de)(de)(de)(de)降(jiang)低都會(hui)影(ying)響封(feng)(feng)(feng)桶(tong)(tong)(tong)質(zhi)(zhi)(zhi)(zhi)量(liang)(liang)。

如何確認(ren)鋼桶的容積？

1、如果您是要(yao)灌裝液體，就需要(yao)按產品的比重（密度）計算，寧波(bo)開(kai)口鋼桶，但必須留(liu)足(zu)因(yin)產品膨脹而(er)產生漲(zhang)裂所需的10%的空間(jian)，以防鋼桶在搬運中跌落時變(bian)形開(kai)裂。

2、如果您是要(yao)盛裝固(gu)體，全開口鋼(gang)桶(tong)，可要(yao)求(qiu)鋼(gang)桶(tong)生產廠家提供相(xiang)同體積(ji)的(de)鋼(gang)桶(tong)試裝，然后換算出該(gai)需裝重(zhong)量(liang)要(yao)求(qiu)體積(ji)鋼(gang)桶(tong)。但也(ye)要(yao)留足5%～10%的(de)空間，用于內襯塑(su)料內袋的(de)包扎，以防鋼(gang)桶(tong)在搬運中因跌(die)落變形而裂開、飛(fei)蓋等現象(xiang)。

鋼桶涂料干燥時(shi)間測定(ding)

涂料以一(yi)定(ding)厚度涂在鋼桶表面上之后(hou)，經過物(wu)理性揮發或化學性氧化聚合作用(yong)，形成固體(ti)薄膜，這(zhe)樣的過程(cheng)(cheng)所需要的時間(jian)稱為干燥時間(jian)。此過程(cheng)(cheng)分(fen)為兩個階段：

(1)表(biao)(biao)干(gan)(gan)：涂(tu)(tu)膜(mo)從流體(ti)至鋼桶表(biao)(biao)面(mian)(mian)形成微薄膜(mo)層時(shi)，稱為(wei)表(biao)(biao)干(gan)(gan)。表(biao)(biao)干(gan)(gan)時(shi)間(jian)的測定方(fang)法(fa)有兩種，即吹(chui)棉(mian)(mian)球法(fa)和指(zhi)觸(chu)法(fa)。吹(chui)棉(mian)(mian)球法(fa)為(wei)在涂(tu)(tu)膜(mo)表(biao)(biao)面(mian)(mian)輕輕放(fang)上一個脫脂棉(mian)(mian)球，嘴距棉(mian)(mian)球10～15cm，水(shui)平方(fang)向輕吹(chui)棉(mian)(mian)球，如(ru)能從涂(tu)(tu)膜(mo)表(biao)(biao)面(mian)(mian)吹(chui)走棉(mian)(mian)球而不留棉(mian)(mian)絲，則(ze)(ze)認(ren)為(wei)已經表(biao)(biao)干(gan)(gan)粘，但(dan)無涂(tu)(tu)料(liao)粘在手上，則(ze)(ze)也認(ren)為(wei)達到表(biao)(biao)干(gan)(gan)了。

(2)實(shi)(shi)干(gan)：涂膜(mo)(mo)從流(liu)體至(zhi)全(quan)部形成固體膜(mo)(mo)層時，稱為實(shi)(shi)干(gan)。測定實(shi)(shi)干(gan)時間的(de)方(fang)法(fa)有(you)濾紙法(fa)、棉球(qiu)法(fa)、刀片法(fa)等。現在介紹為方(fang)便的(de)的(de)刀片法(fa)：用保險刀片在樣板上能刮起涂膜(mo)(mo)，而涂膜(mo)(mo)底層無粘著(zhu)現象，即認為涂膜(mo)(mo)已實(shi)(shi)于。
