在(zai)(zai)靜電(dian)噴(pen)(pen)涂(tu)(tu)中，工(gong)件(jian)距離(li)噴(pen)(pen)頭的距離(li)應在(zai)(zai)150-300mm之間，距離(li)太近容易(yi)(yi)短路(lu)，容易(yi)(yi)造成(cheng)涂(tu)(tu)層有(you)擊穿點，而距離(li)太遠則不易(yi)(yi)上(shang)粉(fen)。在(zai)(zai)整(zheng)個噴(pen)(pen)涂(tu)(tu)過(guo)程中，噴(pen)(pen)和(he)工(gong)件(jian)應始終(zhong)保持(chi)垂(chui)直(zhi)，否則會(hui)(hui)造成(cheng)涂(tu)(tu)料(liao)的浪費，或形成(cheng)“橘皮”現象。同時(shi)要規避(bi)噴(pen)(pen)的弧形移(yi)動，移(yi)動速度要保持(chi)均勻，這(zhe)些(xie)都會(hui)(hui)影響終(zhong)的噴(pen)(pen)涂(tu)(tu)效果。在(zai)(zai)噴(pen)(pen)噴(pen)(pen)涂(tu)(tu)的過(guo)程中，靜電(dian)噴(pen)(pen)槍廠家，噴(pen)(pen)涂(tu)(tu)圖案可能會(hui)(hui)不均勻，這(zhe)時(shi)考(kao)慮有(you)兩點原因：

1、噴粉管磨損；

2、噴(pen)(pen)或粉(fen)管(guan)(guan)堵(du)塞。如果是噴(pen)(pen)粉(fen)管(guan)(guan)磨損，我們需要更換(huan)噴(pen)(pen)粉(fen)管(guan)(guan)，若(ruo)是粉(fen)管(guan)(guan)或噴(pen)(pen)堵(du)塞，我們要先斷(duan)開進(jin)料軟(ruan)管(guan)(guan)與噴(pen)(pen)的連(lian)接，用噴(pen)(pen)氣吹掃噴(pen)(pen)。再斷(duan)開軟(ruan)管(guan)(guan)與噴(pen)(pen)和粉(fen)末(mo)泵，吹掃軟(ruan)管(guan)(guan)，如堵(du)塞比較嚴重，需要更換(huan)進(jin)料軟(ruan)管(guan)(guan)。粉(fen)末(mo)泵也需要拆解和清潔，必(bi)要時需要更換(huan)新的噴(pen)(pen)組件。

噴(pen)涂(tu)(tu)(tu)是將涂(tu)(tu)(tu)料(liao)噴(pen)涂(tu)(tu)(tu)到(dao)諸如板之(zhi)類(lei)的材料(liao)表(biao)面(mian)上的過程(cheng)。根據工藝技術的自動(dong)化程(cheng)度，靜(jing)電噴(pen)槍設(she)備(bei)，噴(pen)涂(tu)(tu)(tu)可分為(wei)手動(dong)噴(pen)涂(tu)(tu)(tu)設(she)備(bei)和自動(dong)噴(pen)涂(tu)(tu)(tu)設(she)備(bei)。讓我們從六個方(fang)面(mian)看一下(xia)自動(dong)噴(pen)涂(tu)(tu)(tu)設(she)備(bei)和手動(dong)噴(pen)涂(tu)(tu)(tu)設(she)備(bei)的優勢。

工作原(yuan)理：手動(dong)噴(pen)涂(tu)(tu)主要是由操作員直(zhi)接噴(pen)涂(tu)(tu)產品表(biao)面，而自動(dong)噴(pen)涂(tu)(tu)則是通過涂(tu)(tu)布(bu)設備帶動(dong)噴(pen)涂(tu)(tu)槍(qiang)移(yi)動(dong)，使噴(pen)涂(tu)(tu)槍(qiang)能夠自動(dong)完成(cheng)各(ge)種噴(pen)涂(tu)(tu)動(dong)作。

精度：自(zi)動噴(pen)(pen)涂(tu)設備的噴(pen)(pen)涂(tu)路徑準確，不(bu)會引(yin)起偏(pian)差(cha)，避免(mian)了傳統噴(pen)(pen)涂(tu)手動操作(zuo)的不(bu)可控性，噴(pen)(pen)涂(tu)的涂(tu)膜質量(liang)高，誤差(cha)小，穩定性高。

④粉末(mo)靜電噴涂(tu)過程中(zhong)配備的粉末(mo)回收裝置(zhi)換色困難(nan)。

⑤由于粉(fen)末(mo)(mo)(mo)靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)涂(tu)(tu)過程中(zhong)未沉積的粉(fen)末(mo)(mo)(mo)需要回收，粉(fen)末(mo)(mo)(mo)靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)涂(tu)(tu)必須在(zai)噴(pen)粉(fen)室內進行，而粉(fen)末(mo)(mo)(mo)靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)槍(qiang)的噴(pen)涂(tu)(tu)圖(tu)形范圍僅為450毫米左(zuo)右(you)，靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)槍(qiang)，因此對大型工(gong)(gong)件(jian)涂(tu)(tu)裝有困難。所(suo)以(yi)，一(yi)般業說:粉(fen)末(mo)(mo)(mo)靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)涂(tu)(tu)特別只適用于中(zhong)小型工(gong)(gong)件(jian)，而且耐磨、耐沖擊(ji)和耐腐蝕等(deng)性(xing)能特別優異(yi)。粉(fen)末(mo)(mo)(mo)靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)涂(tu)(tu)的涂(tu)(tu)層平整、豐滿、光亮，色彩(cai)多樣(yang)，粉(fen)體靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)槍(qiang)，有一(yi)定(ding)的裝飾(shi)性(xing)。尤其(qi)是粉(fen)末(mo)(mo)(mo)靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)涂(tu)(tu)在(zai)涂(tu)(tu)裝過程無溶劑污染，節省(sheng)了環境保護措施費用，工(gong)(gong)序(xu)簡(jian)(jian)化，生(sheng)產周期短，經濟效益(yi)髙(gao)。雖然粉(fen)末(mo)(mo)(mo)涂(tu)(tu)料烘(hong)烤所(suo)需能源增(zeng)加，但(dan)由于粉(fen)末(mo)(mo)(mo)靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)涂(tu)(tu)工(gong)(gong)序(xu)簡(jian)(jian)化，和環保裝置簡(jian)(jian)單，能耗(hao)均有所(suo)減少，所(suo)以(yi)粉(fen)末(mo)(mo)(mo)靜(jing)(jing)(jing)電(dian)(dian)(dian)噴(pen)涂(tu)(tu)在(zai)與溶劑型涂(tu)(tu)料施工(gong)(gong)相比，總的來說能耗(hao)并沒有增(zeng)加多少，甚至有些(xie)情況下(xia)還降(jiang)低(di)了一(yi)些(xie)。
