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(xu)稀料，施(shi)(shi)工(gong)(gong)(gong)(gong)對環(huan)境(jing)對人(ren)體無(wu)毒害；涂層外(wai)觀(guan)質量優異(yi)，附著力及機械強度強；噴(pen)涂施(shi)(shi)工(gong)(gong)(gong)(gong)固(gu)化(hua)時(shi)間短；涂層耐腐耐磨(mo)能力高(gao)出很多；不需(xu)底(di)漆；施(shi)(shi)工(gong)(gong)(gong)(gong)簡便，對工(gong)(gong)(gong)(gong)人(ren)技術要求低；成本(ben)低于噴(pen)漆工(gong)(gong)(gong)(gong)藝(yi)；有些施(shi)(shi)工(gong)(gong)(gong)(gong)場合已經明(ming)確提(ti)出使用靜電噴(pen)塑工(gong)(gong)(gong)(gong)藝(yi)處理(li)；靜電噴(pen)粉噴(pen)涂過程中不會出現噴(pen)漆工(gong)(gong)(gong)(gong)藝(yi)中常見的流淌(tang)現象。

是(shi)利用電暈(yun)放(fang)電現象(xiang)使(shi)粉(fen)末(mo)涂(tu)料吸附(fu)在(zai)電纜橋架上(shang)的(de)。其過(guo)程是(shi)這樣(yang)的(de)：粉(fen)末(mo)涂(tu)料由(you)(you)供(gong)粉(fen)系統借壓(ya)(ya)縮空氣氣體送(song)入噴槍，在(zai)噴槍前端加(jia)有高壓(ya)(ya)靜電發生(sheng)(sheng)(sheng)器產生(sheng)(sheng)(sheng)的(de)高壓(ya)(ya)，由(you)(you)于(yu)電暈(yun)放(fang)電，在(zai)其附(fu)近產生(sheng)(sheng)(sheng)密集的(de)電荷，粉(fen)末(mo)由(you)(you)槍嘴噴出時，形成帶電涂(tu)料粒子(zi)，它受(shou)靜電力的(de)作用，被(bei)吸到與其相反(fan)的(de)工(gong)(gong)(gong)件上(shang)去(qu)，隨著噴上(shang)的(de)粉(fen)末(mo)增多(duo)，電荷積聚(ju)也(ye)越多(duo)，當(dang)達到一定厚度(du)時，由(you)(you)于(yu)產生(sheng)(sheng)(sheng)靜電排斥(chi)作用，便不繼續吸附(fu)，從而(er)使(shi)整個工(gong)(gong)(gong)件獲得一定厚度(du)的(de)粉(fen)末(mo)涂(tu)層，然后經(jing)過(guo)熱使(shi)粉(fen)末(mo)熔融、流平、固(gu)化(hua)，即在(zai)工(gong)(gong)(gong)件表面(mian)形成堅(jian)硬的(de)涂(tu)膜。
