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(bu)需(xu)稀料(liao)，施(shi)工(gong)(gong)對環(huan)境(jing)對人(ren)體無毒害；涂(tu)層(ceng)(ceng)外觀質量優異，附(fu)著力(li)及機械強度強；噴(pen)涂(tu)施(shi)工(gong)(gong)固化(hua)時間(jian)短(duan)；涂(tu)層(ceng)(ceng)耐(nai)腐耐(nai)磨能力(li)高出很多；不(bu)需(xu)底漆；施(shi)工(gong)(gong)簡便，對工(gong)(gong)人(ren)技(ji)術要求低；成本低于噴(pen)漆工(gong)(gong)藝(yi)(yi)；有(you)些施(shi)工(gong)(gong)場合已經明確提(ti)出使用靜(jing)電(dian)噴(pen)塑工(gong)(gong)藝(yi)(yi)處(chu)理；靜(jing)電(dian)噴(pen)粉噴(pen)涂(tu)過程(cheng)中不(bu)會出現噴(pen)漆工(gong)(gong)藝(yi)(yi)中常見的流淌現象(xiang)。

是利用(yong)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)現象使(shi)粉(fen)(fen)末(mo)(mo)涂(tu)(tu)料(liao)吸附在(zai)電(dian)(dian)(dian)纜橋架上(shang)的(de)(de)。其過程(cheng)是這樣(yang)的(de)(de)：粉(fen)(fen)末(mo)(mo)涂(tu)(tu)料(liao)由(you)供粉(fen)(fen)系統借壓(ya)縮空氣氣體送(song)入噴(pen)槍，在(zai)噴(pen)槍前端加有高(gao)壓(ya)靜(jing)電(dian)(dian)(dian)發生器(qi)產(chan)(chan)生的(de)(de)高(gao)壓(ya)，由(you)于電(dian)(dian)(dian)暈放電(dian)(dian)(dian)，在(zai)其附近產(chan)(chan)生密集的(de)(de)電(dian)(dian)(dian)荷，粉(fen)(fen)末(mo)(mo)由(you)槍嘴噴(pen)出(chu)時，形(xing)成帶電(dian)(dian)(dian)涂(tu)(tu)料(liao)粒(li)子，它受靜(jing)電(dian)(dian)(dian)力(li)的(de)(de)作(zuo)(zuo)用(yong)，被吸到(dao)與其相反(fan)的(de)(de)工件(jian)上(shang)去，隨著噴(pen)上(shang)的(de)(de)粉(fen)(fen)末(mo)(mo)增多，電(dian)(dian)(dian)荷積聚也越多，當(dang)達到(dao)一(yi)定(ding)厚(hou)度時，由(you)于產(chan)(chan)生靜(jing)電(dian)(dian)(dian)排斥作(zuo)(zuo)用(yong)，便不(bu)繼續吸附，從而(er)使(shi)整(zheng)個工件(jian)獲得(de)一(yi)定(ding)厚(hou)度的(de)(de)粉(fen)(fen)末(mo)(mo)涂(tu)(tu)層，然后經過熱使(shi)粉(fen)(fen)末(mo)(mo)熔融、流平、固化，即在(zai)工件(jian)表(biao)面形(xing)成堅(jian)硬(ying)的(de)(de)涂(tu)(tu)膜。
