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(shi)工(gong)(gong)對環境對人(ren)體無毒害；涂層外觀質量優異，附著(zhu)力及機(ji)械強(qiang)度強(qiang)；噴(pen)(pen)(pen)(pen)涂施(shi)工(gong)(gong)固化時間(jian)短；涂層耐腐耐磨能力高出(chu)很多；不(bu)需底漆(qi)(qi)；施(shi)工(gong)(gong)簡便(bian)，對工(gong)(gong)人(ren)技術要求低；成本低于噴(pen)(pen)(pen)(pen)漆(qi)(qi)工(gong)(gong)藝(yi)(yi)；有(you)些施(shi)工(gong)(gong)場(chang)合已(yi)經(jing)明(ming)確提(ti)出(chu)使用靜(jing)電噴(pen)(pen)(pen)(pen)塑工(gong)(gong)藝(yi)(yi)處理；靜(jing)電噴(pen)(pen)(pen)(pen)粉(fen)噴(pen)(pen)(pen)(pen)涂過程(cheng)中不(bu)會出(chu)現(xian)噴(pen)(pen)(pen)(pen)漆(qi)(qi)工(gong)(gong)藝(yi)(yi)中常見的流淌(tang)現(xian)象。

是利用(yong)電(dian)(dian)暈(yun)放電(dian)(dian)現象使粉(fen)末(mo)涂(tu)料吸(xi)附(fu)在(zai)(zai)電(dian)(dian)纜橋架上的。其(qi)過(guo)(guo)程是這樣的：粉(fen)末(mo)涂(tu)料由(you)(you)供粉(fen)系統借壓縮空氣(qi)氣(qi)體送入噴(pen)(pen)槍，在(zai)(zai)噴(pen)(pen)槍前(qian)端加有高壓靜(jing)電(dian)(dian)發(fa)生(sheng)器產生(sheng)的高壓，由(you)(you)于(yu)電(dian)(dian)暈(yun)放電(dian)(dian)，在(zai)(zai)其(qi)附(fu)近(jin)產生(sheng)密集的電(dian)(dian)荷，粉(fen)末(mo)由(you)(you)槍嘴噴(pen)(pen)出時(shi)(shi)，形(xing)(xing)成帶(dai)電(dian)(dian)涂(tu)料粒子(zi)，它受靜(jing)電(dian)(dian)力(li)的作用(yong)，被吸(xi)到與其(qi)相反的工(gong)件上去，隨著噴(pen)(pen)上的粉(fen)末(mo)增多(duo)，電(dian)(dian)荷積聚(ju)也越多(duo)，當達到一定(ding)厚度(du)時(shi)(shi)，由(you)(you)于(yu)產生(sheng)靜(jing)電(dian)(dian)排斥(chi)作用(yong)，便不繼續吸(xi)附(fu)，從而使整個工(gong)件獲(huo)得(de)一定(ding)厚度(du)的粉(fen)末(mo)涂(tu)層，然后經過(guo)(guo)熱使粉(fen)末(mo)熔(rong)融、流(liu)平、固(gu)化，即在(zai)(zai)工(gong)件表面形(xing)(xing)成堅硬的涂(tu)膜。
