危包鋼桶的基本條件：

1．內外(wai)包(bao)裝(zhuang)之間要有(you)一定的(de)適(shi)應性，在運輸中內襯(chen)不應與(yu)鋼桶摩(mo)擦并損壞。另外(wai)，鋼桶內焊縫不要有(you)飛刺，以(yi)免(mian)刺破內襯(chen)。

2．鋼(gang)桶(tong)應(ying)(ying)能(neng)經受一(yi)(yi)定范圍內溫度和(he)濕度的(de)(de)(de)(de)變化(hua)。由于出口貿易(yi)一(yi)(yi)般是遠距(ju)離海運，地區的(de)(de)(de)(de)溫濕度差別很大(da)，因此，連云港(gang)開(kai)口鋼(gang)桶(tong)，危險貨物的(de)(de)(de)(de)包裝鋼(gang)桶(tong)必須具有一(yi)(yi)定的(de)(de)(de)(de)防潮外(wai)膜。鋼(gang)桶(tong)涂膜本身應(ying)(ying)具有一(yi)(yi)定的(de)(de)(de)(de)防水(shui)性、抗水(shui)性，具有良好(hao)的(de)(de)(de)(de)耐候性和(he)耐久性。另外(wai)，在灌裝貨物后，開(kai)口鋼(gang)桶(tong)廠家，盛裝液(ye)體的(de)(de)(de)(de)鋼(gang)桶(tong)，必須留有足夠(gou)的(de)(de)(de)(de)空(kong)間，以避免由于溫度變化(hua)液(ye)體膨脹(zhang)而釀成事故。

3．包裝(zhuang)鋼桶的質量、規(gui)格和形(xing)式(shi)要便于裝(zhuang)卸、運輸和貯存。要符合國(guo)際鋼桶標準的要求。

鋼桶表面的除銹方法(fa)(fa)分為(wei)化學(xue)方法(fa)(fa)和(he)機械法(fa)(fa)兩(liang)大類。

化(hua)(hua)(hua)(hua)學(xue)法(fa)除銹(xiu)是(shi)利用(yong)化(hua)(hua)(hua)(hua)學(xue)瓜(gua)或(huo)電化(hua)(hua)(hua)(hua)學(xue)瓜(gua)從(cong)鋼(gang)(gang)桶表(biao)面溶解掉一般銹(xiu)跡、氧(yang)(yang)化(hua)(hua)(hua)(hua)皮及各種腐蝕產物而不影(ying)響鋼(gang)(gang)桶基(ji)體金屬。常(chang)用(yong)的化(hua)(hua)(hua)(hua)學(xue)除銹(xiu)方(fang)法(fa)是(shi)酸(suan)(suan)洗，即利用(yong)有(you)機酸(suan)(suan)或(huo)無(wu)機酸(suan)(suan)使鋼(gang)(gang)桶表(biao)面的氧(yang)(yang)化(hua)(hua)(hua)(hua)物 和黃銹(xiu)從(cong)鋼(gang)(gang)桶表(biao)面折出。

機(ji)械除(chu)(chu)銹(xiu)是利(li)用摩擦(ca)、錘擊、沖刷等機(ji)械作用力，使(shi)磨粒在鋼(gang)桶表面除(chu)(chu)去銹(xiu)跡、高(gao)溫氧化(hua)皮等污物(wu)。鋼(gang)桶企(qi)業常(chang)用的(de)機(ji)械除(chu)(chu)銹(xiu) 方法(fa)是手(shou)工打(da)磨才(cai)機(ji)械打(da)磨埤(pi)工除(chu)(chu)銹(xiu)是使(shi)用簡單工具(ju)用人力進 行除(chu)(chu)銹(xiu)，其方法(fa)簡單易行，但勞動強度(du)大(da)，生產效率低且除(chu)(chu)銹(xiu)質量(liang)差(cha)，一般(ban)只能(neng)除(chu)(chu)去疏松的(de)或(huo)較輕的(de)鐵(tie)銹(xiu)。

鋼桶的優勢

1、經濟(ji)效益顯著 減(jian)小(xiao)用(yong)材厚度，開(kai)口鋼桶批發，節約了(le)原材料(liao)，給企(qi)業帶來的經濟(ji)效益是顯著的。

2、堆(dui)碼運(yun)輸(shu)(shu)方(fang)便(bian)，未(wei)(wei)縮(suo)(suo)頸(jing)的(de)(de)(de)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)底比(bi)較容易(yi)地套(tao)堆(dui)在縮(suo)(suo)頸(jing)后的(de)(de)(de)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)頂上，相對(dui)平穩安全。反之，全開口鋼(gang)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)，縮(suo)(suo)頸(jing)后的(de)(de)(de)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)底也(ye)比(bi)較容易(yi)地套(tao)堆(dui)在未(wei)(wei)縮(suo)(suo)頸(jing)的(de)(de)(de)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)頂上，但未(wei)(wei)縮(suo)(suo)頸(jing)的(de)(de)(de)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)頂的(de)(de)(de)強度(du)并未(wei)(wei)增強，僅僅方(fang)便(bian)堆(dui)碼。錐形鋼(gang)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)空桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)可以桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)套(tao)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)運(yun)輸(shu)(shu)，增加了(le)(le)(le)運(yun)量，降低(di)了(le)(le)(le)運(yun)輸(shu)(shu)成本，很受歡迎。但桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)口不能縮(suo)(suo)頸(jing)，因(yin)而桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)口的(de)(de)(de)強度(du)未(wei)(wei)增強，只能縮(suo)(suo)桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)底，否(fou)則(ze)，就失(shi)去了(le)(le)(le)錐形桶(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)優勢。
