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)需稀料，施工(gong)(gong)(gong)(gong)對環境對人體無毒(du)害；涂(tu)(tu)層(ceng)外(wai)觀質(zhi)量優異，附著(zhu)力及(ji)機(ji)械強度強；噴(pen)涂(tu)(tu)施工(gong)(gong)(gong)(gong)固化時間(jian)短；涂(tu)(tu)層(ceng)耐腐耐磨能力高(gao)出很多(duo)；不(bu)需底(di)漆；施工(gong)(gong)(gong)(gong)簡便，對工(gong)(gong)(gong)(gong)人技術要求低；成(cheng)本(ben)低于噴(pen)漆工(gong)(gong)(gong)(gong)藝(yi)；有些施工(gong)(gong)(gong)(gong)場合已經明確提出使用靜(jing)電噴(pen)塑工(gong)(gong)(gong)(gong)藝(yi)處理；靜(jing)電噴(pen)粉噴(pen)涂(tu)(tu)過(guo)程中(zhong)不(bu)會出現(xian)噴(pen)漆工(gong)(gong)(gong)(gong)藝(yi)中(zhong)常見的流淌現(xian)象。

是利用電(dian)(dian)暈放電(dian)(dian)現象使粉(fen)末(mo)(mo)(mo)涂(tu)料(liao)(liao)吸(xi)附(fu)在電(dian)(dian)纜橋架上(shang)的(de)。其(qi)過程是這樣的(de)：粉(fen)末(mo)(mo)(mo)涂(tu)料(liao)(liao)由供粉(fen)系統借(jie)壓(ya)縮(suo)空氣氣體送(song)入噴(pen)(pen)槍，在噴(pen)(pen)槍前端加有高壓(ya)靜電(dian)(dian)發生(sheng)器(qi)產(chan)生(sheng)的(de)高壓(ya)，由于電(dian)(dian)暈放電(dian)(dian)，在其(qi)附(fu)近產(chan)生(sheng)密集的(de)電(dian)(dian)荷，粉(fen)末(mo)(mo)(mo)由槍嘴噴(pen)(pen)出時，形成帶(dai)電(dian)(dian)涂(tu)料(liao)(liao)粒子，它受靜電(dian)(dian)力的(de)作(zuo)用，被吸(xi)到與(yu)其(qi)相反的(de)工(gong)件(jian)上(shang)去，隨著噴(pen)(pen)上(shang)的(de)粉(fen)末(mo)(mo)(mo)增(zeng)多，電(dian)(dian)荷積聚也越多，當達到一(yi)定厚度時，由于產(chan)生(sheng)靜電(dian)(dian)排斥作(zuo)用，便不繼續吸(xi)附(fu)，從而使整(zheng)個工(gong)件(jian)獲得(de)一(yi)定厚度的(de)粉(fen)末(mo)(mo)(mo)涂(tu)層，然后經過熱使粉(fen)末(mo)(mo)(mo)熔融、流平、固化(hua)，即在工(gong)件(jian)表面形成堅(jian)硬的(de)涂(tu)膜。
