鋼桶的涂裝方法

鋼桶成(cheng)型(xing)后(hou)，已(yi)經(jing)成(cheng)為(wei)一個(ge)可以實(shi)用的鋼桶，但(dan)為(wei)了增加其美觀及防腐蝕能力(li)，烤漆(qi)鋼桶，還必須給其進(jin)行涂裝(zhuang)處理，這個(ge)過程一般(ban)包括(kuo)涂裝(zhuang)前(qian)清(qing)洗(xi)、水份烘干、涂漆(qi)、涂層(ceng)烘干、印刷等工藝過程。

國內采用廣泛的涂裝工藝是油漆涂裝工藝。涂裝工藝可以保(bao)證鋼(gang)桶外觀(guan)質量(liang)，增強鋼(gang)桶抗腐蝕能力。

涂(tu)裝(zhuang)工(gong)藝按噴(pen)涂(tu)方式可分為空氣(qi)噴(pen)涂(tu)、靜電噴(pen)涂(tu)和高(gao)壓無氣(qi)噴(pen)涂(tu)等幾

在涂(tu)裝前應進(jin)行除油(you)、除銹、磷(lin)化、清(qing)洗、烘干等(deng)處理(li)，以保證涂(tu)裝質(zhi)量，50升鋼桶(tong)，提高漆膜(mo)附(fu)著力。對(dui)于表面要求不高的鋼桶(tong)產品，也(ye)可采用人(ren)工擦桶(tong)的辦法，有效(xiao)降低成(cheng)本。

涂(tu)(tu)裝(zhuang)的后一道工序是標(biao)志(zhi)的印刷。以前鋼桶(tong)的標(biao)志(zhi)是采用(yong)空氣(qi)噴(pen)涂(tu)(tu)法，利用(yong)鏤空的標(biao)志(zhi)版進行噴(pen)字。隨著用(yong)戶對鋼桶(tong)外表(biao)質量要求的提高，標(biao)志(zhi)印刷已逐漸采用(yong)效(xiao)果更好的絲(si)網印刷和熱(re)轉 印技(ji)術。

鋼桶(tong)(tong)的修補(bu)(bu)(bu)方法(fa)(fa) （1）傳統(tong)修補(bu)(bu)(bu)法(fa)(fa)——氣焊(han)(han)補(bu)(bu)(bu)漏(lou) 特(te)(te)點：熱影(ying)響(xiang)區比較(jiao)大，能造(zao)成表面氧(yang)化，桶(tong)(tong)身(shen)變形、卷邊內(nei)密封膠燒焦失效(xiao)，一點滲漏(lou)須補(bu)(bu)(bu)焊(han)(han)整圈(quan)。 （2）釬焊(han)(han)修補(bu)(bu)(bu)法(fa)(fa) 特(te)(te)點：熱影(ying)響(xiang)區比較(jiao)小(xiao)，不會致(zhi)使桶(tong)(tong)身(shen)成形。但(dan)補(bu)(bu)(bu)焊(han)(han)前處理(li)比較(jiao)復雜，工作效(xiao)率低。 （3）弧焊(han)(han)修補(bu)(bu)(bu)法(fa)(fa) 特(te)(te)點：熱影(ying)響(xiang)區比較(jiao)小(xiao)，不會產生表面氧(yang)化，鋼桶(tong)(tong)，補(bu)(bu)(bu)焊(han)(han)效(xiao)果好，工作效(xiao)率相對較(jiao)高。 （4）膠粘劑膠接法(fa)(fa) 特(te)(te)點：成本低，工作，操(cao)作簡單，但(dan)適用范圍有(you)限。 2、鋼桶(tong)(tong)的應急修補(bu)(bu)(bu)方法(fa)(fa) （1）環氧(yang)樹脂(zhi)補(bu)(bu)(bu)漏(lou)法(fa)(fa) 先配好補(bu)(bu)(bu)漏(lou)膠，再添入(ru)桶(tong)(tong)身(shen)接縫(feng)中，晾干即可，但(dan)適用范圍要注意(yi)。 （2）輥輪(lun)再次(ci)壓(ya)緊法(fa)(fa) 必須返廠，采用較(jiao)小(xiao)尺寸槽形的輥輪(lun)，再在封口機(ji)上(shang)(shang)滾壓(ya)一次(ci)，可減(jian)少(shao)80%以上(shang)(shang)的漏(lou)桶(tong)(tong)。

鋼桶用鋼板的分類

鋼(gang)(gang)(gang)(gang)(gang)桶用鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)按(an)厚(hou)度(du)分(fen)類(lei)(lei)：薄(bo)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、中(zhong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、厚(hou)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、特厚(hou)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。按(an)生產方法(fa)分(fen)類(lei)(lei)：熱(re)軋鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、冷軋鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。按(an)表面特征分(fen)類(lei)(lei)：鍍(du)鋅板(ban)(ban)(ban)(ban)(ban)(ban)(ban)（熱(re)鍍(du)鋅板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、電鍍(du)鋅板(ban)(ban)(ban)(ban)(ban)(ban)(ban)）、鍍(du)錫(xi)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、復合鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、彩色涂(tu)層鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。 按(an)用途分(fen)類(lei)(lei)：橋梁鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、鍋爐(lu)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、造船(chuan)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、裝甲鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、汽車鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、屋(wu)面鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、結構(gou)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)、電工鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)（硅(gui)鋼(gang)(gang)(gang)(gang)(gang)片(pian)）、彈簧(huang)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，其他。。。。。。。。。。。。。。。
