噴塑也就(jiu)是咱(zan)們常講(jiang)的靜電粉末噴涂，它是運(yun)用靜電發生(sheng)器使塑料(liao)粉末帶電，吸附(fu)在鐵板外表，然后(hou)通過180～220℃的烘烤，使粉末熔化(hua)黏附(fu)在金屬外表，噴塑產品(pin)多用于戶內(nei)運(yun)用的箱體，漆(qi)膜呈現平(ping)光(guang)或(huo)啞光(guang)作用。噴塑粉首要有(you)丙烯(xi)酸粉末、聚酯粉末

靜電噴涂工藝（靜電噴塑）具有的優勢:

不需稀料，施工對環境，對人體無毒害；涂層外觀質量優異，附著力及機械強度強；噴涂施工固化時刻短；金屬噴涂廠家涂(tu)(tu)層耐腐耐磨才能高出(chu)很多；不需底漆；施工(gong)簡(jian)便，對工(gong)人技(ji)術(shu)要求低(di)；本錢(qian)低(di)于噴(pen)(pen)漆工(gong)藝；有(you)些施工(gong)場合已經明確提出(chu)有(you)必(bi)要運用(yong)靜(jing)電(dian)噴(pen)(pen)塑工(gong)藝處理；靜(jing)電(dian)噴(pen)(pen)粉噴(pen)(pen)涂(tu)(tu)進程中(zhong)不會(hui)出(chu)現噴(pen)(pen)漆工(gong)藝中(zhong)常見的流淌現象。

靜電噴塑的工藝原理(li):

是運用電暈放電現象使粉末涂料吸附在工件上的。其進程是這樣的：粉末涂料由供粉系統借壓縮空氣氣體送入噴槍，金屬板材噴塑在(zai)噴(pen)(pen)槍前端(duan)加有(you)高(gao)壓靜(jing)電(dian)(dian)(dian)發(fa)(fa)生(sheng)(sheng)(sheng)器發(fa)(fa)生(sheng)(sheng)(sheng)的(de)(de)高(gao)壓，由于電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)，在(zai)其(qi)(qi)鄰近(jin)發(fa)(fa)生(sheng)(sheng)(sheng)密集的(de)(de)電(dian)(dian)(dian)荷(he)，粉末(mo)由槍嘴噴(pen)(pen)出時(shi)，構成帶電(dian)(dian)(dian)涂(tu)料粒(li)子，它受靜(jing)電(dian)(dian)(dian)力的(de)(de)作用(yong)，被吸到與(yu)其(qi)(qi)相反的(de)(de)工(gong)(gong)件上(shang)去(qu)，隨著噴(pen)(pen)上(shang)的(de)(de)粉末(mo)增多，電(dian)(dian)(dian)荷(he)積聚也(ye)越(yue)多，當到達必(bi)定(ding)(ding)厚度時(shi)，由于發(fa)(fa)生(sheng)(sheng)(sheng)靜(jing)電(dian)(dian)(dian)排斥(chi)作用(yong)，便不持續(xu)吸附，從(cong)而使整(zheng)個工(gong)(gong)件取得(de)必(bi)定(ding)(ding)厚度的(de)(de)粉末(mo)涂(tu)層，然后通(tong)過熱使粉末(mo)熔融、流(liu)平、固(gu)化，即在(zai)工(gong)(gong)件外表構成堅(jian)硬的(de)(de)涂(tu)膜。
