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(liao)，施(shi)(shi)工(gong)(gong)(gong)對環境對人體無毒(du)害；涂層外(wai)觀質(zhi)量優異(yi)，附著力及機械強度強；噴(pen)(pen)涂施(shi)(shi)工(gong)(gong)(gong)固化(hua)時間短；涂層耐腐(fu)耐磨能力高(gao)出(chu)很多；不需底漆(qi)；施(shi)(shi)工(gong)(gong)(gong)簡便，對工(gong)(gong)(gong)人技術要求低(di)；成本低(di)于噴(pen)(pen)漆(qi)工(gong)(gong)(gong)藝(yi)；有些(xie)施(shi)(shi)工(gong)(gong)(gong)場合已經明確(que)提(ti)出(chu)使用靜(jing)(jing)電(dian)噴(pen)(pen)塑工(gong)(gong)(gong)藝(yi)處理；靜(jing)(jing)電(dian)噴(pen)(pen)粉噴(pen)(pen)涂過程(cheng)中(zhong)不會(hui)出(chu)現(xian)噴(pen)(pen)漆(qi)工(gong)(gong)(gong)藝(yi)中(zhong)常見的流淌現(xian)象(xiang)。

是(shi)利用電(dian)暈放(fang)電(dian)現象使粉(fen)(fen)末(mo)涂(tu)(tu)(tu)料(liao)(liao)吸附(fu)在(zai)電(dian)纜(lan)橋架上的(de)(de)(de)。其(qi)過程(cheng)是(shi)這樣的(de)(de)(de)：粉(fen)(fen)末(mo)涂(tu)(tu)(tu)料(liao)(liao)由(you)(you)供粉(fen)(fen)系(xi)統借壓(ya)縮(suo)空(kong)氣氣體送入噴(pen)槍(qiang)(qiang)，在(zai)噴(pen)槍(qiang)(qiang)前端加有高(gao)壓(ya)靜電(dian)發生(sheng)器產生(sheng)的(de)(de)(de)高(gao)壓(ya)，由(you)(you)于(yu)電(dian)暈放(fang)電(dian)，在(zai)其(qi)附(fu)近(jin)產生(sheng)密集的(de)(de)(de)電(dian)荷，粉(fen)(fen)末(mo)由(you)(you)槍(qiang)(qiang)嘴噴(pen)出時，形成帶電(dian)涂(tu)(tu)(tu)料(liao)(liao)粒子，它受靜電(dian)力的(de)(de)(de)作用，被吸到與(yu)其(qi)相反的(de)(de)(de)工件(jian)上去，隨著(zhu)噴(pen)上的(de)(de)(de)粉(fen)(fen)末(mo)增(zeng)多(duo)(duo)，電(dian)荷積聚也越多(duo)(duo)，當達到一(yi)定厚(hou)度(du)時，由(you)(you)于(yu)產生(sheng)靜電(dian)排斥作用，便不繼(ji)續吸附(fu)，從而使整個工件(jian)獲得一(yi)定厚(hou)度(du)的(de)(de)(de)粉(fen)(fen)末(mo)涂(tu)(tu)(tu)層，然后經過熱使粉(fen)(fen)末(mo)熔融、流平、固(gu)化，即在(zai)工件(jian)表面形成堅硬的(de)(de)(de)涂(tu)(tu)(tu)膜。
