電(dian)泳(yong)設備線的導電(dian)裝置(zhi)介紹

     在陽極電(dian)(dian)泳(yong)(yong)涂裝(zhuang)時(shi)，從(cong)整流器出來(lai)的負極連(lian)接(jie)一組不銹鋼(gang)板，正極連(lian)接(jie)至工件，工件通(tong)電(dian)(dian)的方式有(you)兩(liang)種(zhong)，一種(zhong)是帶(dai)電(dian)(dian)入槽(cao)，射陽涂裝(zhuang)電(dian)(dian)泳(yong)(yong)線(xian)，一種(zhong)是入槽(cao)后通(tong)電(dian)(dian)。兩(liang)個通(tong)電(dian)(dian)方法各有(you)其(qi)優缺點：帶(dai)電(dian)(dian)入槽(cao)可縮短電(dian)(dian)泳(yong)(yong)槽(cao)長度，但漆膜(mo)表面易出現斑(ban)馬(ma)紋；入槽(cao)后通(tong)電(dian)(dian)，能夠避免(mian)前述的涂膜(mo)外觀(guan)的弊病，但電(dian)(dian)源系統較復(fu)雜龐大，涂裝(zhuang)電(dian)(dian)泳(yong)(yong)線(xian)標準，要求有(you)可調時(shi)間的漸升壓(ya)電(dian)(dian)路，以防止電(dian)(dian)流脈(mo)沖損壞涂層及電(dian)(dian)氣設備。

     電(dian)(dian)(dian)沉積時，涂裝電(dian)(dian)(dian)泳線廠價，電(dian)(dian)(dian)壓(ya)從(cong)零伏升到工作電(dian)(dian)(dian)壓(ya)的時間約需要10-20秒，整流器輸出脈動(dong)(dong)率很重要，電(dian)(dian)(dian)壓(ya)脈動(dong)(dong)幅度不能超過平(ping)均直流電(dian)(dian)(dian)壓(ya)的5%-10%。在滿負荷情況下，電(dian)(dian)(dian)壓(ya)脈動(dong)(dong)率也應小(xiao)于5%-10%。

     電(dian)(dian)(dian)泳(yong)涂(tu)裝(zhuang)的(de)直流電(dian)(dian)(dian)源電(dian)(dian)(dian)壓應在0-350V范(fan)圍內可(ke)調，直流電(dian)(dian)(dian)流一(yi)般(ban)與涂(tu)裝(zhuang)面(mian)積及涂(tu)料(liao)的(de)庫侖效率有(you)關，平均電(dian)(dian)(dian)流強(qiang)(qiang)度(du)可(ke)按下式(shi)計算(suan)：（一(yi)般(ban)而言，電(dian)(dian)(dian)泳(yong)所需電(dian)(dian)(dian)流強(qiang)(qiang)度(du)為10-20A/M2）

涂裝電泳線對消防、環保的要求：

1消防形式(shi)(shi)：噴漆室采(cai)用(yong)水(shui)噴淋自動(dong)滅火(huo)裝(zhuang)置，調漆間采(cai)用(yong)二氧化碳自動(dong)滅火(huo)裝(zhuang)置。若綱領較低(di)，噴漆室亦可采(cai)用(yong)設置推車式(shi)(shi)滅火(huo)器等(deng)消防形式(shi)(shi)。

2防(fang)爆(bao)要求：噴漆(qi)(qi)室(shi)(shi)、流平室(shi)(shi)、調漆(qi)(qi)間所有電氣(qi)元(yuan)(yuan)件要求防(fang)爆(bao)；面漆(qi)(qi)烘干(gan)爐和距烘干(gan)爐出口(kou)處3m距離內的電器元(yuan)(yuan)件要求防(fang)爆(bao)；噴漆(qi)(qi)室(shi)(shi)、流平室(shi)(shi)、調漆(qi)(qi)間設置可(ke)燃氣(qi)體濃度報警裝置。

3主(zhu)要廢水及排放量（單(dan)個(ge)工(gong)件(jian)的排放量指(zhi)標）
