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)對(dui)環境對(dui)人體無毒害；涂(tu)層(ceng)外(wai)觀質量(liang)優異(yi)，附著力及機械強度強；噴(pen)涂(tu)施工(gong)固化時間短；涂(tu)層(ceng)耐(nai)腐(fu)耐(nai)磨(mo)能力高(gao)出(chu)很(hen)多；不需底漆(qi)；施工(gong)簡便(bian)，對(dui)工(gong)人技術要求低；成本低于噴(pen)漆(qi)工(gong)藝；有(you)些施工(gong)場合已經明確提出(chu)使用靜(jing)電噴(pen)塑(su)工(gong)藝處(chu)理；靜(jing)電噴(pen)粉噴(pen)涂(tu)過程中(zhong)(zhong)不會(hui)出(chu)現(xian)噴(pen)漆(qi)工(gong)藝中(zhong)(zhong)常見(jian)的流淌現(xian)象(xiang)。

是利用電(dian)(dian)(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)(dian)(dian)現象(xiang)使(shi)粉(fen)(fen)末(mo)涂(tu)料吸附在電(dian)(dian)(dian)(dian)(dian)纜橋架上(shang)的(de)。其(qi)過(guo)程是這樣的(de)：粉(fen)(fen)末(mo)涂(tu)料由供粉(fen)(fen)系(xi)統借(jie)壓縮(suo)空氣氣體送入噴(pen)槍(qiang)，在噴(pen)槍(qiang)前端加有高壓靜(jing)電(dian)(dian)(dian)(dian)(dian)發生器產生的(de)高壓，由于電(dian)(dian)(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)(dian)(dian)，在其(qi)附近產生密集的(de)電(dian)(dian)(dian)(dian)(dian)荷(he)，粉(fen)(fen)末(mo)由槍(qiang)嘴噴(pen)出(chu)時，形成(cheng)帶(dai)電(dian)(dian)(dian)(dian)(dian)涂(tu)料粒(li)子，它受(shou)靜(jing)電(dian)(dian)(dian)(dian)(dian)力的(de)作用，被吸到與(yu)其(qi)相反(fan)的(de)工件上(shang)去(qu)，隨著噴(pen)上(shang)的(de)粉(fen)(fen)末(mo)增(zeng)多(duo)(duo)，電(dian)(dian)(dian)(dian)(dian)荷(he)積聚也越多(duo)(duo)，當達到一定厚(hou)度時，由于產生靜(jing)電(dian)(dian)(dian)(dian)(dian)排斥(chi)作用，便(bian)不繼續吸附，從而使(shi)整(zheng)個工件獲得一定厚(hou)度的(de)粉(fen)(fen)末(mo)涂(tu)層，然后經過(guo)熱(re)使(shi)粉(fen)(fen)末(mo)熔融、流平、固化，即在工件表面形成(cheng)堅硬的(de)涂(tu)膜。
