韓意(yi)機電設備【瑞士金(jin)馬授(shou)權(quan)的代理商】為您(nin)分享：教你如何(he)操作(zuo)噴槍及(ji)噴涂的幾大要(yao)領

在噴(pen)涂(tu)作業過程中，噴(pen)槍操作不(bu)(bu)(bu)當就會影響(xiang)產品噴(pen)涂(tu)效果(guo)，瑞(rui)士金(jin)馬靜電噴(pen)槍，好的(de)噴(pen)涂(tu)效果(guo)表現在：1、涂(tu)層分布平均 2、涂(tu)層不(bu)(bu)(bu)能過厚(hou)不(bu)(bu)(bu)能太薄(bo)。噴(pen)涂(tu)需(xu)注意的(de)幾點(dian)問題：

噴(pen)(pen)(pen)(pen)嘴出(chu)(chu)料(liao)(liao)口與(yu)被涂(tu)(tu)物(wu)之間的(de)(de)距(ju)離(li)(li)稱為槍(qiang)(qiang)距(ju)。槍(qiang)(qiang)距(ju)越(yue)小(xiao)，噴(pen)(pen)(pen)(pen)涂(tu)(tu)壓(ya)力就(jiu)(jiu)越(yue)大(da)(da)，產品受到氣壓(ya)的(de)(de)沖擊也(ye)越(yue)大(da)(da)，涂(tu)(tu)層(ceng)(ceng)就(jiu)(jiu)會出(chu)(chu)現不平(ping)(ping)均的(de)(de)情況(kuang)，產生涂(tu)(tu)抹(mo)過厚(hou)的(de)(de)問(wen)題。槍(qiang)(qiang)距(ju)越(yue)大(da)(da)，噴(pen)(pen)(pen)(pen)涂(tu)(tu)壓(ya)力越(yue)小(xiao)，涂(tu)(tu)料(liao)(liao)易(yi)流失，使被涂(tu)(tu)物(wu)部分噴(pen)(pen)(pen)(pen)料(liao)(liao)過少，涂(tu)(tu)抹(mo)達不到的(de)(de)厚(hou)度(du)。噴(pen)(pen)(pen)(pen)涂(tu)(tu)扇(shan)面(mian)與(yu)被涂(tu)(tu)物(wu)面(mian)呈現垂(chui)直(zhi)的(de)(de)狀態。手工(gong)操縱噴(pen)(pen)(pen)(pen)槍(qiang)(qiang)時(shi)，噴(pen)(pen)(pen)(pen)涂(tu)(tu)寬(kuan)度(du)不能出(chu)(chu)現過大(da)(da)的(de)(de)情況(kuang)，否(fou)則(ze)會出(chu)(chu)現涂(tu)(tu)層(ceng)(ceng)平(ping)(ping)均的(de)(de)問(wen)題。噴(pen)(pen)(pen)(pen)槍(qiang)(qiang)運轉(zhuan)的(de)(de)目的(de)(de)要(yao)始(shi)終與(yu)被涂(tu)(tu)物(wu)面(mian)平(ping)(ping)行，與(yu)噴(pen)(pen)(pen)(pen)涂(tu)(tu)扇(shan)面(mian)垂(chui)直(zhi)，運轉(zhuan)速率(lv)不穩，涂(tu)(tu)層(ceng)(ceng)厚(hou)度(du)不平(ping)(ping)均，運轉(zhuan)速率(lv)過快(kuai)涂(tu)(tu)層(ceng)(ceng)太薄(bo)，運轉(zhuan)速率(lv)過慢涂(tu)(tu)層(ceng)(ceng)太厚(hou)。總而言之，金(jin)馬噴(pen)(pen)(pen)(pen)槍(qiang)(qiang)多少錢，在使用噴(pen)(pen)(pen)(pen)涂(tu)(tu)設備的(de)(de)時(shi)候，要(yao)做到力度(du)適(shi)中，距(ju)離(li)(li)合(he)適(shi)才可以，這樣(yang)才能夠得到想(xiang)要(yao)的(de)(de)涂(tu)(tu)裝效果(guo)，在施(shi)工(gong)后(hou)，一(yi)些掃尾(wei)的(de)(de)事情也(ye)需要(yao)完(wan)善起來，涂(tu)(tu)料(liao)(liao)及幫助器具的(de)(de)收拾，使用后(hou)的(de)(de)殘剩涂(tu)(tu)料(liao)(liao)要(yao)保留這都是(shi)需要(yao)注意的(de)(de)問(wen)題。

對(dui)于粉(fen)(fen)末靜電(dian)(dian)噴涂工藝，重(zhong)點要(yao)考慮的(de)(de)(de)(de)是粉(fen)(fen)末涂料(liao)(liao)(liao)顆粒接(jie)受電(dian)(dian)荷，保持(chi)電(dian)(dian)荷和(he)電(dian)(dian)荷分布情(qing)況(kuang)，這(zhe)(zhe)直接(jie)影(ying)響到粉(fen)(fen)末對(dui)工件的(de)(de)(de)(de)吸附(fu)力(li)和(he)沉積效率，此外，重(zhong)要(yao)的(de)(de)(de)(de)是，金(jin)馬噴槍報(bao)價，未(wei)經(jing)固化(hua)的(de)(de)(de)(de)粉(fen)(fen)末涂層必須經(jing)得起(qi)傳(chuan)送機構的(de)(de)(de)(de)機械震(zhen)動(dong)而不掉粉(fen)(fen)。實際上，影(ying)響粉(fen)(fen)末顆粒接(jie)受電(dian)(dian)荷和(he)保持(chi)電(dian)(dian)荷的(de)(de)(de)(de)主要(yao)因素(su)是粉(fen)(fen)末涂料(liao)(liao)(liao)的(de)(de)(de)(de)介電(dian)(dian)常(chang)數(shu)(shu)，粉(fen)(fen)末的(de)(de)(de)(de)介電(dian)(dian)常(chang)數(shu)(shu)越(yue)低，顆粒帶電(dian)(dian)越(yue)容易(yi)(yi)，但(dan)(dan)喪(sang)失電(dian)(dian)荷也越(yue)容易(yi)(yi)，這(zhe)(zhe)反(fan)映粉(fen)(fen)末在工件上的(de)(de)(de)(de)吸咐力(li)不牢(lao)，略受振動(dong)就掉粉(fen)(fen)，對(dui)于靜電(dian)(dian)噴涂的(de)(de)(de)(de)粉(fen)(fen)末涂料(liao)(liao)(liao)，應盡可能的(de)(de)(de)(de)用(yong)高介電(dian)(dian)常(chang)數(shu)(shu)的(de)(de)(de)(de)，它將使粉(fen)(fen)末吸附(fu)力(li)大大提高。涂膜更均(jun)勻。但(dan)(dan)是介電(dian)(dian)常(chang)數(shu)(shu)高的(de)(de)(de)(de)粉(fen)(fen)末涂料(liao)(liao)(liao)，帶電(dian)(dian)較困難，這(zhe)(zhe)就需要(yao)在靜電(dian)(dian)噴粉(fen)(fen)槍的(de)(de)(de)(de)結構上加以改進(jin)，采用(yong)多電(dian)(dian)極的(de)(de)(de)(de)強(qiang)制帶電(dian)(dian)的(de)(de)(de)(de)結構。

對于粉(fen)末(mo)(mo)(mo)涂(tu)料(liao)來講，它均(jun)(jun)是高(gao)分(fen)子化合(he)物組成的(de)(de)（如：環(huan)氧粉(fen)末(mo)(mo)(mo)、聚酯粉(fen)末(mo)(mo)(mo)等），它們對工件(jian)的(de)(de)吸附力(li)(li)(li)主要有(you)二個：庫(ku)侖力(li)(li)(li)（靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)(li)）和(he)VandeWaals力(li)(li)(li)（分(fen)子力(li)(li)(li)）。高(gao)分(fen)子化合(he)物均(jun)(jun)有(you)較(jiao)高(gao)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)率(lv)(lv)(lv)，因此庫(ku)侖力(li)(li)(li)（靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)(li)）是大而可靠的(de)(de)。粉(fen)末(mo)(mo)(mo)本身(shen)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)率(lv)(lv)(lv)，將決(jue)定粉(fen)末(mo)(mo)(mo)在(zai)一定的(de)(de)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場強度下的(de)(de)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態；如：當粉(fen)末(mo)(mo)(mo)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)率(lv)(lv)(lv)在(zai)1013歐姆時，靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)只要30-50KV，就(jiu)能使(shi)粉(fen)末(mo)(mo)(mo)良好的(de)(de)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)；而粉(fen)末(mo)(mo)(mo)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)率(lv)(lv)(lv)在(zai)108-109歐姆時，則要施加100-120KV的(de)(de)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)才能得(de)到上(shang)述(shu)的(de)(de)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)效果。粉(fen)末(mo)(mo)(mo)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)率(lv)(lv)(lv)與靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)關系（圖略(lve)）。能否自動限制粉(fen)末(mo)(mo)(mo)沉積(ji)岐的(de)(de)厚度，這與粉(fen)末(mo)(mo)(mo)本身(shen)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)率(lv)(lv)(lv)關系很大，實(shi)驗證實(shi)，只有(you)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)率(lv)(lv)(lv)的(de)(de)粉(fen)末(mo)(mo)(mo)才能得(de)到合(he)適的(de)(de)涂(tu)膜。
