涂(tu)裝(zhuang)生產線工藝流程(cheng)分(fen)為：前(qian)處理、噴粉涂(tu)裝(zhuang)、加熱固化。

　　(1)涂裝(zhuang)(zhuang)(zhuang)生(sheng)(sheng)產線(xian)(xian)前(qian)(qian)(qian)(qian)處(chu)(chu)(chu)理(li)(li)(li)(li)工(gong)(gong)(gong)段(duan)的(de)(de)(de)生(sheng)(sheng)產前(qian)(qian)(qian)(qian)處(chu)(chu)(chu)理(li)(li)(li)(li)有手動(dong)簡易工(gong)(gong)(gong)藝和(he)自(zi)動(dong)前(qian)(qian)(qian)(qian)處(chu)(chu)(chu)理(li)(li)(li)(li)工(gong)(gong)(gong)藝，后者(zhe)又分(fen)自(zi)動(dong)噴(pen)淋和(he)自(zi)動(dong)浸噴(pen)兩種(zhong)工(gong)(gong)(gong)藝。工(gong)(gong)(gong)件在(zai)噴(pen)粉之前(qian)(qian)(qian)(qian)必(bi)須(xu)進(jin)(jin)行表(biao)面(mian)(mian)處(chu)(chu)(chu)理(li)(li)(li)(li)去(qu)(qu)油(you)去(qu)(qu)銹。在(zai)這一(yi)工(gong)(gong)(gong)段(duan)所(suo)用藥液較多(duo)，主要(yao)(yao)有除銹劑(ji)、除油(you)劑(ji)、表(biao)調劑(ji)、磷化劑(ji)等(deng)等(deng)。在(zai)涂裝(zhuang)(zhuang)(zhuang)生(sheng)(sheng)產線(xian)(xian)前(qian)(qian)(qian)(qian)處(chu)(chu)(chu)理(li)(li)(li)(li)工(gong)(gong)(gong)段(duan)或(huo)車間，要(yao)(yao)注意的(de)(de)(de)就是制定必(bi)要(yao)(yao)的(de)(de)(de)強酸強堿購買、運輸(shu)、保管(guan)和(he)使用制度，給工(gong)(gong)(gong)人提供必(bi)要(yao)(yao)的(de)(de)(de)保護(hu)著裝(zhuang)(zhuang)(zhuang)，安全可靠的(de)(de)(de)盛裝(zhuang)(zhuang)(zhuang)、搬運、配置(zhi)器具(ju)，以(yi)及(ji)(ji)制定萬一(yi)發生(sheng)(sheng)事故時(shi)的(de)(de)(de)緊急處(chu)(chu)(chu)理(li)(li)(li)(li)措施、搶救辦法。其(qi)次，在(zai)涂裝(zhuang)(zhuang)(zhuang)生(sheng)(sheng)產線(xian)(xian)前(qian)(qian)(qian)(qian)處(chu)(chu)(chu)理(li)(li)(li)(li)工(gong)(gong)(gong)段(duan)，由于存在(zai)一(yi)定量(liang)的(de)(de)(de)廢(fei)氣(qi)、廢(fei)液等(deng)三(san)廢(fei)物質(zhi)，所(suo)以(yi)在(zai)環保措施方面(mian)(mian)，必(bi)須(xu)配置(zhi)抽氣(qi)排氣(qi)、排液和(he)三(san)廢(fei)處(chu)(chu)(chu)理(li)(li)(li)(li)裝(zhuang)(zhuang)(zhuang)置(zhi)。前(qian)(qian)(qian)(qian)處(chu)(chu)(chu)理(li)(li)(li)(li)過的(de)(de)(de)工(gong)(gong)(gong)件質(zhi)量(liang)，由于前(qian)(qian)(qian)(qian)處(chu)(chu)(chu)理(li)(li)(li)(li)液及(ji)(ji)涂裝(zhuang)(zhuang)(zhuang)生(sheng)(sheng)產線(xian)(xian)工(gong)(gong)(gong)藝流程不盡(jin)相同，其(qi)質(zhi)量(liang)當有差異。處(chu)(chu)(chu)理(li)(li)(li)(li)較好(hao)的(de)(de)(de)工(gong)(gong)(gong)件，表(biao)面(mian)(mian)油(you)、銹去(qu)(qu)盡(jin)，為了防(fang)止短時(shi)間內(nei)再(zai)次生(sheng)(sheng)銹，一(yi)般(ban)應(ying)在(zai)前(qian)(qian)(qian)(qian)處(chu)(chu)(chu)理(li)(li)(li)(li)后幾道工(gong)(gong)(gong)序(xu)，進(jin)(jin)行磷化或(huo)鈍化處(chu)(chu)(chu)理(li)(li)(li)(li)：在(zai)噴(pen)粉前(qian)(qian)(qian)(qian)，還應(ying)將已磷化的(de)(de)(de)工(gong)(gong)(gong)件進(jin)(jin)行干(gan)(gan)燥，去(qu)(qu)其(qi)表(biao)面(mian)(mian)水分(fen)。小(xiao)批量(liang)單件生(sheng)(sheng)產，一(yi)般(ban)采用自(zi)然晾干(gan)(gan)、曬干(gan)(gan)、風干(gan)(gan)。而對于大批量(liang)之流水作業，一(yi)般(ban)采取(qu)低溫烘干(gan)(gan)，采用烘箱(xiang)或(huo)烘道。

　　(2)噴(pen)(pen)(pen)粉涂(tu)裝(zhuang)的組織生(sheng)(sheng)產對(dui)于(yu)小(xiao)批量(liang)工(gong)件(jian)，一(yi)(yi)般(ban)(ban)采取(qu)手動(dong)噴(pen)(pen)(pen)粉裝(zhuang)置(zhi)(zhi)，而對(dui)于(yu)大(da)批量(liang)工(gong)件(jian)，一(yi)(yi)般(ban)(ban)采用手動(dong)或(huo)自動(dong)噴(pen)(pen)(pen)粉裝(zhuang)置(zhi)(zhi)。無論是手動(dong)噴(pen)(pen)(pen)粉或(huo)自動(dong)噴(pen)(pen)(pen)粉，把住質(zhi)量(liang)關是非常重(zhong)要(yao)(yao)的。要(yao)(yao)確(que)保(bao)被噴(pen)(pen)(pen)工(gong)件(jian)著(zhu)粉均(jun)勻、厚度(du)一(yi)(yi)致(zhi)，防止薄(bo)噴(pen)(pen)(pen)、漏噴(pen)(pen)(pen)、擦落等缺(que)陷。在(zai)涂(tu)裝(zhuang)生(sheng)(sheng)產線這一(yi)(yi)工(gong)序(xu)，還應(ying)注意(yi)工(gong)件(jian)之(zhi)掛(gua)(gua)鉤部分(fen)，在(zai)進入固(gu)化之(zhi)前(qian)，應(ying)盡可(ke)能將附著(zhu)其(qi)上的粉末吹掉(diao)，防止掛(gua)(gua)鉤上之(zhi)多余粉末固(gu)化，有的對(dui)固(gu)化前(qian)去掉(diao)余粉確(que)有困(kun)難時，應(ying)及時剝(bo)離掛(gua)(gua)鉤上已固(gu)化之(zhi)粉膜，從而確(que)保(bao)掛(gua)(gua)鉤導電良好，以利下批工(gong)件(jian)易于(yu)著(zhu)粉。

　　(3)涂裝生產線固化工序(xu)生產這一工序(xu)應注(zhu)意(yi)的事項有：噴好的工件，如果是小(xiao)批量(liang)單件生產，進(jin)(jin)固化爐前注(zhu)意(yi)防止碰落(luo)粉(fen)(fen)末(mo)(mo)，如有擦粉(fen)(fen)現(xian)象，應及時(shi)補噴粉(fen)(fen)末(mo)(mo)。烘烤時(shi)嚴格工藝及溫度、時(shi)間控制，切實注(zhu)意(yi)防止色差、過(guo)烘或(huo)(huo)時(shi)間過(guo)短造成固化不(bu)足(zu)。對于(yu)大批量(liang)自動輸送的工件，在進(jin)(jin)烘道(dao)(dao)前同樣要仔細檢(jian)查是否漏噴、噴薄或(huo)(huo)局部擦粉(fen)(fen)現(xian)象，如發現(xian)不(bu)合(he)格件，應把好關防止進(jin)(jin)入烘道(dao)(dao)，盡可能取下重噴。如個別工件因薄噴不(bu)合(he)格，在固化出烘道(dao)(dao)后可以(yi)重噴再次固化。
