涂裝生產線簡介

涂(tu)裝生產線(xian)(xian)(xian)主要由(you)前處理(li)(li)電泳線(xian)(xian)(xian)（電泳漆(qi)是早開發的水性涂(tu)料，它的主要特點是涂(tu)裝，經濟安全(quan)(quan)，污染少(shao)，可實(shi)現完全(quan)(quan)自動化管理(li)(li)。涂(tu)裝電泳漆(qi)之前需(xu)要進行(xing)預處理(li)(li)）、密封(feng)底涂(tu)線(xian)(xian)(xian)、中涂(tu)線(xian)(xian)(xian)、面涂(tu)線(xian)(xian)(xian)、精修(xiu)線(xian)(xian)(xian)及其烘干系(xi)統(tong)組成。涂(tu)裝生產線(xian)(xian)(xian)全(quan)(quan)線(xian)(xian)(xian)工件輸送(song)(song)系(xi)統(tong)采(cai)用(yong)空中懸(xuan)掛和地面滑橇(qiao)相結合(he)的機械化輸送(song)(song)方式，運(yun)行(xing)平穩、快速便捷，采(cai)用(yong)PLC可控編程，根(gen)據生產工藝的實(shi)際要求編程控制——實(shi)行(xing)現場總線(xian)(xian)(xian)中心監控，分(fen)區自動實(shi)現轉接運(yun)行(xing)。

涂(tu)(tu)裝生(sheng)產(chan)線(xian)全線(xian)各(ge)(ge)烘(hong)(hong)干系統的(de)(de)設(she)計(ji)參照國外的(de)(de)設(she)計(ji)理念和參數，噴粉(fen)生(sheng)產(chan)線(xian)供(gong)應商，烘(hong)(hong)道室體均(jun)采用橋式結構（密封底涂(tu)(tu)爐除外），保證了(le)爐溫(wen)的(de)(de)均(jun)勻(yun)性和穩定性，提高了(le)熱(re)能(neng)的(de)(de)效益性；供(gong)熱(re)裝置引(yin)進了(le)加(jia)拿(na)大(da)科邁科公司的(de)(de)產(chan)品，選用進口的(de)(de)燃燒器和控制(zhi)系統，經測試各(ge)(ge)烘(hong)(hong)干系統運行良好穩定，溫(wen)度曲線(xian)平(ping)滑持續(xu)。

作(zuo)為(wei)干(gan)(gan)(gan)燥(zao)(zao)(zao)固化工藝來(lai)說，一般有熱(re)(re)(re)(re)(re)(re)(re)風循環(huan)式和(he)輻射(she)加(jia)熱(re)(re)(re)(re)(re)(re)(re)式。在五六(liu)十(shi)(shi)年(nian)(nian)代主要(yao)(yao)用(yong)(yong)(yong)蒸汽(qi)或電(dian)加(jia)熱(re)(re)(re)(re)(re)(re)(re)器作(zuo)熱(re)(re)(re)(re)(re)(re)(re)源(yuan)來(lai)干(gan)(gan)(gan)燥(zao)(zao)(zao)固化，從60年(nian)(nian)開始(shi)出(chu)(chu)現紅(hong)外線(xian)干(gan)(gan)(gan)燥(zao)(zao)(zao)，70年(nian)(nian)代出(chu)(chu)現遠紅(hong)外干(gan)(gan)(gan)燥(zao)(zao)(zao)和(he)微波干(gan)(gan)(gan)燥(zao)(zao)(zao)，靜電(dian)噴粉生產(chan)線(xian)，1994年(nian)(nian)出(chu)(chu)現了(le)高(gao)紅(hong)外快速加(jia)熱(re)(re)(re)(re)(re)(re)(re)技術。隨著對干(gan)(gan)(gan)燥(zao)(zao)(zao)溫度(du)的(de)(de)(de)控制(zhi)要(yao)(yao)求(qiu)和(he)溫度(du)控制(zhi)均勻性(xing)的(de)(de)(de)要(yao)(yao)求(qiu)，出(chu)(chu)現了(le)在爐內(nei)進行(xing)(xing)熱(re)(re)(re)(re)(re)(re)(re)風循環(huan)，80年(nian)(nian)代后期出(chu)(chu)現了(le)燃(ran)油（氣(qi)(qi)）熱(re)(re)(re)(re)(re)(re)(re)風循環(huan)的(de)(de)(de)干(gan)(gan)(gan)燥(zao)(zao)(zao)爐（固化爐），而(er)且燃(ran)油（氣(qi)(qi)）熱(re)(re)(re)(re)(re)(re)(re)風干(gan)(gan)(gan)燥(zao)(zao)(zao)（固化）的(de)(de)(de)應(ying)(ying)(ying)用(yong)(yong)(yong)漸趨廣泛(fan)；一般來(lai)說，目前國內(nei)采(cai)用(yong)(yong)(yong)電(dian)加(jia)熱(re)(re)(re)(re)(re)(re)(re)熱(re)(re)(re)(re)(re)(re)(re)風干(gan)(gan)(gan)燥(zao)(zao)(zao)爐較(jiao)多，但用(yong)(yong)(yong)電(dian)作(zuo)為(wei)烘(hong)烤熱(re)(re)(re)(re)(re)(re)(re)源(yuan)往(wang)往(wang)不是(shi)一種經濟(ji)的(de)(de)(de)方法，特(te)別(bie)是(shi)增(zeng)(zeng)容費的(de)(de)(de)負擔，使(shi)建設(she)投資增(zeng)(zeng)大(da)(da)；但電(dian)加(jia)熱(re)(re)(re)(re)(re)(re)(re)的(de)(de)(de)設(she)計與(yu)運行(xing)(xing)管(guan)理較(jiao)簡便，操作(zuo)比較(jiao)方便，所以(yi)在較(jiao)小的(de)(de)(de)干(gan)(gan)(gan)燥(zao)(zao)(zao)爐中應(ying)(ying)(ying)用(yong)(yong)(yong)仍然較(jiao)多。采(cai)用(yong)(yong)(yong)燃(ran)油（氣(qi)(qi)）加(jia)熱(re)(re)(re)(re)(re)(re)(re)取代電(dian)烘(hong)烤的(de)(de)(de)方法是(shi)一項(xiang)重(zhong)大(da)(da)節能(neng)技術，隨著國內(nei)工業發(fa)展，燃(ran)油（氣(qi)(qi)）的(de)(de)(de)供(gong)應(ying)(ying)(ying)已基(ji)本(ben)解決或便于解決，噴粉生產(chan)線(xian)哪(na)家好，如額(e)定供(gong)熱(re)(re)(re)(re)(re)(re)(re)每小時達到幾十(shi)(shi)萬至上百萬大(da)(da)卡的(de)(de)(de)大(da)(da)型(xing)干(gan)(gan)(gan)燥(zao)(zao)(zao)爐設(she)計中，用(yong)(yong)(yong)電(dian)加(jia)熱(re)(re)(re)(re)(re)(re)(re)與(yu)用(yong)(yong)(yong)燃(ran)油加(jia)熱(re)(re)(re)(re)(re)(re)(re)的(de)(de)(de)干(gan)(gan)(gan)燥(zao)(zao)(zao)爐運行(xing)(xing)成本(ben)相差達3-5倍，故在涂裝(zhuang)生產(chan)線(xian)設(she)計中，可以(yi)加(jia)以(yi)推(tui)廣應(ying)(ying)(ying)用(yong)(yong)(yong)。
