噴塑橋架

噴塑電纜橋架是將塑料粉末噴涂在電纜橋架上的一種表面處理方法。

不需稀料，施工(gong)(gong)(gong)對(dui)環境(jing)對(dui)人體無毒害；涂(tu)層外觀質量優異，附著(zhu)力及(ji)機(ji)械強度強；噴(pen)(pen)涂(tu)施工(gong)(gong)(gong)固化(hua)時間短；涂(tu)層耐腐耐磨能(neng)力高(gao)出很多；不需底(di)漆(qi)；施工(gong)(gong)(gong)簡(jian)便，對(dui)工(gong)(gong)(gong)人技術要求低(di)；成本(ben)低(di)于噴(pen)(pen)漆(qi)工(gong)(gong)(gong)藝；有些施工(gong)(gong)(gong)場合已經明(ming)確(que)提出使用靜電噴(pen)(pen)塑工(gong)(gong)(gong)藝處(chu)理；靜電噴(pen)(pen)粉噴(pen)(pen)涂(tu)過程中(zhong)不會(hui)出現噴(pen)(pen)漆(qi)工(gong)(gong)(gong)藝中(zhong)常見的(de)流淌現象(xiang)。

是利用電(dian)暈放電(dian)現象(xiang)使粉(fen)(fen)末(mo)(mo)涂料(liao)吸(xi)附在(zai)電(dian)纜橋架上(shang)的(de)(de)。其過程是這樣的(de)(de)：粉(fen)(fen)末(mo)(mo)涂料(liao)由(you)供(gong)粉(fen)(fen)系統(tong)借壓(ya)(ya)(ya)縮空(kong)氣氣體(ti)送入噴槍(qiang)，在(zai)噴槍(qiang)前端加(jia)有高(gao)壓(ya)(ya)(ya)靜電(dian)發生(sheng)器(qi)產生(sheng)的(de)(de)高(gao)壓(ya)(ya)(ya)，由(you)于電(dian)暈放電(dian)，在(zai)其附近產生(sheng)密集的(de)(de)電(dian)荷，粉(fen)(fen)末(mo)(mo)由(you)槍(qiang)嘴噴出(chu)時，形成(cheng)帶電(dian)涂料(liao)粒子，它(ta)受(shou)靜電(dian)力(li)的(de)(de)作用，被(bei)吸(xi)到與(yu)其相(xiang)反的(de)(de)工件(jian)上(shang)去，隨著(zhu)噴上(shang)的(de)(de)粉(fen)(fen)末(mo)(mo)增多(duo)，電(dian)荷積聚也(ye)越多(duo)，當達到一(yi)定(ding)厚度(du)時，由(you)于產生(sheng)靜電(dian)排斥作用，便不繼續吸(xi)附，從而使整(zheng)個(ge)工件(jian)獲得(de)一(yi)定(ding)厚度(du)的(de)(de)粉(fen)(fen)末(mo)(mo)涂層，然后(hou)經過熱(re)使粉(fen)(fen)末(mo)(mo)熔(rong)融、流平、固化，即在(zai)工件(jian)表(biao)面形成(cheng)堅(jian)硬的(de)(de)涂膜。
