電泳涂裝線之設備介紹
電泳涂裝的設備是由電泳槽、攪拌裝置、涂料過濾裝置、溫度調節裝置、涂料管理裝置、直流電源裝置、電泳涂裝后的水洗裝置、超濾裝置、烘烤裝置、備用罐等組成。
電(dian)(dian)(dian)泳槽槽體(ti)的(de)(de)(de)(de)大(da)小(xiao)(xiao)及形(xing)狀需根(gen)據(ju)工(gong)(gong)件(jian)大(da)小(xiao)(xiao)、形(xing)狀和(he)施工(gong)(gong)工(gong)(gong)藝確定(ding)。在保證一(yi)定(ding)的(de)(de)(de)(de)極間距離(li)條件(jian)下,應(ying)(ying)盡可(ke)(ke)能設(she)計(ji)小(xiao)(xiao)些(xie)。槽內(nei)裝(zhuang)有過濾(lv)裝(zhuang)置及溫度調節(jie)裝(zhuang)置,以保證漆(qi)(qi)液(ye)(ye)(ye)一(yi)定(ding)的(de)(de)(de)(de)溫度和(he)除去循(xun)環(huan)漆(qi)(qi)液(ye)(ye)(ye)中的(de)(de)(de)(de)雜質(zhi)(zhi)和(he)氣(qi)泡(pao)。攪(jiao)拌裝(zhuang)置可(ke)(ke)使(shi)工(gong)(gong)作漆(qi)(qi)液(ye)(ye)(ye)保持均(jun)勻一(yi)致,多采用(yong)循(xun)環(huan)泵,漆(qi)(qi)液(ye)(ye)(ye)的(de)(de)(de)(de)循(xun)環(huan)一(yi)般(ban)(ban)(ban)每小(xiao)(xiao)時4~6次,當循(xun)環(huan)泵開動時,槽內(nei)漆(qi)(qi)液(ye)(ye)(ye)液(ye)(ye)(ye)面(mian)應(ying)(ying)均(jun)勻翻動。涂料(liao)管(guan)理裝(zhuang)置的(de)(de)(de)(de)作用(yong)在于(yu)補充(chong)調整涂料(liao)成分(fen),控制槽液(ye)(ye)(ye)的(de)(de)(de)(de)PH值,用(yong)隔(ge)膜(mo)電(dian)(dian)(dian)極除去中和(he)劑和(he)用(yong)超濾(lv)裝(zhuang)置排(pai)除低(di)分(fen)子(zi)量(liang)成分(fen)等。電(dian)(dian)(dian)泳電(dian)(dian)(dian)源的(de)(de)(de)(de)選擇,一(yi)般(ban)(ban)(ban)采用(yong)直流(liu)(liu)電(dian)(dian)(dian)源。整流(liu)(liu)設(she)備(bei)可(ke)(ke)采用(yong)硅(gui)整流(liu)(liu)器或(huo)可(ke)(ke)控硅(gui)。電(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)大(da)小(xiao)(xiao)與涂料(liao)的(de)(de)(de)(de)性質(zhi)(zhi)、溫度、工(gong)(gong)作面(mian)積、通電(dian)(dian)(dian)方式等有關,一(yi)般(ban)(ban)(ban)為(wei)30~50A/m2。水(shui)洗裝(zhuang)置用(yong)于(yu)電(dian)(dian)(dian)泳涂裝(zhuang)前后工(gong)(gong)件(jian)的(de)(de)(de)(de)沖洗,一(yi)般(ban)(ban)(ban)用(yong)去離(li)子(zi)水(shui),但需加壓(ya)設(she)備(bei),常用(yong)的(de)(de)(de)(de)是一(yi)種帶(dai)螺旋(xuan)體(ti)的(de)(de)(de)(de)淋洗噴嘴。烘烤裝(zhuang)置用(yong)來促(cu)進(jin)電(dian)(dian)(dian)泳涂料(liao)的(de)(de)(de)(de)干(gan)燥成膜(mo),可(ke)(ke)采用(yong)電(dian)(dian)(dian)阻爐、感應(ying)(ying)電(dian)(dian)(dian)熱爐和(he)紅外線烘烤設(she)備(bei)。烘房(fang)設(she)計(ji)要有預熱、加熱和(he)后熱三段,應(ying)(ying)根(gen)據(ju)涂料(liao)的(de)(de)(de)(de)品種和(he)工(gong)(gong)件(jian)的(de)(de)(de)(de)情況制訂(ding)。
