將塑料粉末噴涂(tu)在(zai)零件上的(de)一種(zhong)表(biao)面(mian)處理(li)方法。優點(dian)是不(bu)需(xu)稀料，施(shi)工(gong)(gong)對環境無污染，對人體(ti)無毒(du)害；涂(tu)層(ceng)外觀質量優異，附著力及(ji)機(ji)械強(qiang)度強(qiang)；噴涂(tu)施(shi)工(gong)(gong)固化時間短(duan)；涂(tu)層(ceng)耐腐(fu)耐磨能力高出很(hen)多(duo)、不(bu)需(xu)底漆、施(shi)工(gong)(gong)簡(jian)便(bian)、對工(gong)(gong)人技(ji)術(shu)要求低(di)、成本低(di)于噴漆工(gong)(gong)藝(yi)。

將(jiang)塑料粉末通過高壓靜電設(she)備(bei)充電，在電場的作用(yong)下，將(jiang)涂(tu)(tu)料噴涂(tu)(tu)到工件(jian)的表(biao)面，粉末會被(bei)均勻(yun)地吸附(fu)(fu)在工件(jian)表(biao)面，形成(cheng)粉狀(zhuang)的涂(tu)(tu)層;而粉狀(zhuang)涂(tu)(tu)層經過高溫(wen)烘(hong)烤(kao)后流平固化，塑料顆粒會融化成(cheng)一層致密的效果各異的最終保護(hu)涂(tu)(tu)層;牢牢附(fu)(fu)著(zhu)在工件(jian)表(biao)面，噴塑產(chan)品多用(yong)于戶(hu)內使(shi)用(yong)的箱體(ti),漆膜(mo)呈現(xian)平光或啞光效果。噴塑粉主(zhu)要(yao)有(you)丙烯酸粉末、聚酯粉末等。
