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)(gong)對環(huan)境對人(ren)體無(wu)毒害；涂(tu)層外觀質量優異，附著力及機械強度強；噴(pen)(pen)涂(tu)施(shi)工(gong)(gong)(gong)固化時間(jian)短；涂(tu)層耐腐耐磨能力高出很多；不需底漆；施(shi)工(gong)(gong)(gong)簡便，對工(gong)(gong)(gong)人(ren)技術要求低；成本低于(yu)噴(pen)(pen)漆工(gong)(gong)(gong)藝；有(you)些施(shi)工(gong)(gong)(gong)場合已經明確提出使用靜(jing)電噴(pen)(pen)塑工(gong)(gong)(gong)藝處(chu)理；靜(jing)電噴(pen)(pen)粉(fen)噴(pen)(pen)涂(tu)過程(cheng)中(zhong)不會出現噴(pen)(pen)漆工(gong)(gong)(gong)藝中(zhong)常見(jian)的流淌現象。

是利用電(dian)暈放電(dian)現(xian)象(xiang)使(shi)粉末涂料吸(xi)(xi)附(fu)(fu)在(zai)電(dian)纜橋架上的(de)(de)。其(qi)(qi)過程是這樣的(de)(de)：粉末涂料由(you)(you)供粉系統借壓(ya)縮空氣氣體送入噴槍(qiang)，在(zai)噴槍(qiang)前(qian)端(duan)加有高(gao)壓(ya)靜電(dian)發生(sheng)器產生(sheng)的(de)(de)高(gao)壓(ya)，由(you)(you)于電(dian)暈放電(dian)，在(zai)其(qi)(qi)附(fu)(fu)近產生(sheng)密(mi)集的(de)(de)電(dian)荷(he)，粉末由(you)(you)槍(qiang)嘴噴出(chu)時(shi)(shi)，形(xing)成帶電(dian)涂料粒子，它受靜電(dian)力的(de)(de)作用，被吸(xi)(xi)到與(yu)其(qi)(qi)相反的(de)(de)工件(jian)上去，隨著噴上的(de)(de)粉末增多，電(dian)荷(he)積聚也越多，當達到一定厚度(du)時(shi)(shi)，由(you)(you)于產生(sheng)靜電(dian)排斥作用，便不繼(ji)續吸(xi)(xi)附(fu)(fu)，從而使(shi)整個(ge)工件(jian)獲得一定厚度(du)的(de)(de)粉末涂層，然后經過熱使(shi)粉末熔融、流平、固化，即在(zai)工件(jian)表面形(xing)成堅硬的(de)(de)涂膜(mo)。
