鋼桶(tong)包裝(zhuang)用鋼材主要有下(xia)面幾類：

1、冷軋低碳薄鋼板

主(zhu)要用(yong)于(yu)制造(zao)大中型運輸包(bao)裝(zhuang)鋼桶。

2、熱軋低碳薄鋼板

主要(yao)用(yong)于制造大中型運輸包裝鋼桶(tong)。

3、鍍鋅薄鋼板

又稱(cheng)白鐵皮，是制桶z理想的(de)材(cai)料，主(zhu)要用(yong)于制造工業產品包裝(zhuang)的(de)各種鋼桶。

4、鍍錫薄鋼板

又稱馬口鐵，是(shi)制造(zao)小型鋼桶的主(zhu)要材料，大量用于(yu)制罐(guan)工(gong)業，也(ye)可(ke)以用來制造(zao)其它食(shi)(shi)品和非(fei)食(shi)(shi)品的小型桶罐(guan)容器。

5、鍍鉻薄鋼板

又(you)稱無錫(xi)鋼板，是制造小型桶罐的(de)主(zhu)要材料之(zhi)一，可部分(fen)代(dai)替(ti)馬(ma)口鐵(tie)，主(zhu)要用于制造食品包(bao)裝容器。

鋼桶的涂裝方法

鋼桶(tong)(tong)成(cheng)型后，鋼桶(tong)(tong)生產廠家(jia)，已經成(cheng)為(wei)一(yi)個可以實用的鋼桶(tong)(tong)，但為(wei)了增(zeng)加其美觀及防(fang)腐蝕能力，50升(sheng)鋼桶(tong)(tong)，還(huan)必須給其進行涂裝(zhuang)處理，這(zhe)個過程一(yi)般包括涂裝(zhuang)前清洗、水份烘干、涂漆、涂層(ceng)烘干、印刷(shua)等工藝過程。

國(guo)內采用廣(guang)泛的涂(tu)裝(zhuang)工藝是油漆涂(tu)裝(zhuang)工藝。涂(tu)裝(zhuang)工藝可以保(bao)證鋼(gang)桶外觀質量，增強(qiang)鋼(gang)桶抗腐蝕(shi)能力(li)。

涂(tu)裝工藝按噴(pen)涂(tu)方式可(ke)分(fen)為空氣噴(pen)涂(tu)、靜電噴(pen)涂(tu)和高壓無氣噴(pen)涂(tu)等(deng)幾

在涂裝(zhuang)前應進行除(chu)油、除(chu)銹、磷(lin)化、清洗(xi)、烘干等(deng)處(chu)理，以保證涂裝(zhuang)質量，提高漆膜(mo)附著力。對于(yu)表(biao)面要求不高的鋼桶產品，也可采用人工擦桶的辦法，有效(xiao)降低成(cheng)本。

涂(tu)裝的后一(yi)道工序是標(biao)志的印刷。以前鋼桶的標(biao)志是采用空氣噴涂(tu)法，利(li)用鏤空的標(biao)志版進行(xing)噴字。隨著用戶對鋼桶外表質量要求的提高(gao)，標(biao)志印刷已逐(zhu)漸(jian)采用效果更(geng)好的絲(si)網(wang)印刷和熱轉 印技術。

鋼桶的優勢

1、經濟效(xiao)益顯著 減小用材厚(hou)度，節約了(le)原材料(liao)，給企業帶(dai)來(lai)的經濟效(xiao)益是顯著的。

2、堆(dui)碼運(yun)輸(shu)方便，鋼桶(tong)(tong)(tong)(tong)(tong)廠家(jia)，未(wei)(wei)(wei)(wei)縮頸的桶(tong)(tong)(tong)(tong)(tong)底比(bi)較容易地套堆(dui)在縮頸后的桶(tong)(tong)(tong)(tong)(tong)頂(ding)上(shang)，相對平穩安(an)全。反之，縮頸后的桶(tong)(tong)(tong)(tong)(tong)底也比(bi)較容易地套堆(dui)在未(wei)(wei)(wei)(wei)縮頸的桶(tong)(tong)(tong)(tong)(tong)頂(ding)上(shang)，但未(wei)(wei)(wei)(wei)縮頸的桶(tong)(tong)(tong)(tong)(tong)頂(ding)的強度(du)并未(wei)(wei)(wei)(wei)增(zeng)強，僅(jin)僅(jin)方便堆(dui)碼。錐(zhui)形(xing)鋼桶(tong)(tong)(tong)(tong)(tong)的空桶(tong)(tong)(tong)(tong)(tong)可以桶(tong)(tong)(tong)(tong)(tong)套桶(tong)(tong)(tong)(tong)(tong)的運(yun)輸(shu)，鋼桶(tong)(tong)(tong)(tong)(tong)，增(zeng)加了運(yun)量，降低了運(yun)輸(shu)成本(ben)，很受歡迎。但桶(tong)(tong)(tong)(tong)(tong)口不能縮頸，因而桶(tong)(tong)(tong)(tong)(tong)口的強度(du)未(wei)(wei)(wei)(wei)增(zeng)強，只能縮桶(tong)(tong)(tong)(tong)(tong)底，否(fou)則，就失去了錐(zhui)形(xing)桶(tong)(tong)(tong)(tong)(tong)的優勢。
