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(shi)工(gong)(gong)對環(huan)境對人體(ti)無毒害；涂(tu)(tu)(tu)層外觀質(zhi)量優異，附著力及機(ji)械強度強；噴(pen)涂(tu)(tu)(tu)施(shi)工(gong)(gong)固化時(shi)間短(duan)；涂(tu)(tu)(tu)層耐(nai)腐(fu)耐(nai)磨(mo)能力高(gao)出(chu)很(hen)多；不需底漆(qi)(qi)；施(shi)工(gong)(gong)簡(jian)便，對工(gong)(gong)人技術要(yao)求低(di)；成本低(di)于噴(pen)漆(qi)(qi)工(gong)(gong)藝(yi)；有些施(shi)工(gong)(gong)場合已經明確提出(chu)使用靜電(dian)噴(pen)塑工(gong)(gong)藝(yi)處(chu)理；靜電(dian)噴(pen)粉噴(pen)涂(tu)(tu)(tu)過程中不會出(chu)現(xian)噴(pen)漆(qi)(qi)工(gong)(gong)藝(yi)中常見的流(liu)淌現(xian)象。

是利用電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)現象(xiang)使粉(fen)末(mo)涂(tu)(tu)料(liao)吸(xi)附在電(dian)(dian)(dian)纜橋架上的(de)(de)。其過程是這樣的(de)(de)：粉(fen)末(mo)涂(tu)(tu)料(liao)由(you)供粉(fen)系統借壓(ya)縮空(kong)氣氣體(ti)送(song)入噴槍(qiang)，在噴槍(qiang)前端加有(you)高壓(ya)靜(jing)電(dian)(dian)(dian)發(fa)生(sheng)器產(chan)生(sheng)的(de)(de)高壓(ya)，由(you)于(yu)電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)，在其附近(jin)產(chan)生(sheng)密集(ji)的(de)(de)電(dian)(dian)(dian)荷，粉(fen)末(mo)由(you)槍(qiang)嘴(zui)噴出(chu)時，形(xing)成帶電(dian)(dian)(dian)涂(tu)(tu)料(liao)粒子(zi)，它受靜(jing)電(dian)(dian)(dian)力的(de)(de)作用，被吸(xi)到(dao)與其相反的(de)(de)工(gong)件上去，隨著噴上的(de)(de)粉(fen)末(mo)增(zeng)多(duo)，電(dian)(dian)(dian)荷積聚(ju)也越多(duo)，當達到(dao)一(yi)定(ding)厚度時，由(you)于(yu)產(chan)生(sheng)靜(jing)電(dian)(dian)(dian)排(pai)斥(chi)作用，便不繼續吸(xi)附，從(cong)而使整個(ge)工(gong)件獲得一(yi)定(ding)厚度的(de)(de)粉(fen)末(mo)涂(tu)(tu)層，然后經過熱使粉(fen)末(mo)熔融、流平、固化，即在工(gong)件表面形(xing)成堅(jian)硬(ying)的(de)(de)涂(tu)(tu)膜。
