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，施工(gong)(gong)(gong)對環境對人(ren)體無毒害；涂層(ceng)外觀(guan)質量優異(yi)，附著力及機械強度(du)強；噴(pen)涂施工(gong)(gong)(gong)固化時間短；涂層(ceng)耐腐耐磨能力高出(chu)(chu)很多；不需(xu)底漆；施工(gong)(gong)(gong)簡便，對工(gong)(gong)(gong)人(ren)技(ji)術要求低；成本低于噴(pen)漆工(gong)(gong)(gong)藝(yi)；有些施工(gong)(gong)(gong)場合已(yi)經明確提出(chu)(chu)使用(yong)靜電噴(pen)塑工(gong)(gong)(gong)藝(yi)處理；靜電噴(pen)粉噴(pen)涂過程中(zhong)不會出(chu)(chu)現(xian)噴(pen)漆工(gong)(gong)(gong)藝(yi)中(zhong)常見(jian)的流淌(tang)現(xian)象。

是利(li)用電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)現象使粉(fen)末涂料吸附(fu)在(zai)電(dian)(dian)(dian)纜橋架上(shang)(shang)的(de)(de)(de)。其(qi)過程是這樣的(de)(de)(de)：粉(fen)末涂料由(you)供粉(fen)系統借壓縮空(kong)氣(qi)氣(qi)體送入噴(pen)(pen)槍，在(zai)噴(pen)(pen)槍前端加有高壓靜(jing)電(dian)(dian)(dian)發生器(qi)產生的(de)(de)(de)高壓，由(you)于電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)，在(zai)其(qi)附(fu)近產生密集的(de)(de)(de)電(dian)(dian)(dian)荷，粉(fen)末由(you)槍嘴(zui)噴(pen)(pen)出時(shi)，形(xing)(xing)成(cheng)帶電(dian)(dian)(dian)涂料粒子，它受(shou)靜(jing)電(dian)(dian)(dian)力的(de)(de)(de)作(zuo)(zuo)用，被吸到(dao)與(yu)其(qi)相反的(de)(de)(de)工件(jian)上(shang)(shang)去，隨著噴(pen)(pen)上(shang)(shang)的(de)(de)(de)粉(fen)末增多(duo)(duo)，電(dian)(dian)(dian)荷積聚(ju)也越多(duo)(duo)，當(dang)達到(dao)一(yi)定厚度(du)(du)時(shi)，由(you)于產生靜(jing)電(dian)(dian)(dian)排斥作(zuo)(zuo)用，便不繼續吸附(fu)，從而使整個工件(jian)獲得一(yi)定厚度(du)(du)的(de)(de)(de)粉(fen)末涂層，然后經過熱(re)使粉(fen)末熔(rong)融、流平(ping)、固化，即在(zai)工件(jian)表面形(xing)(xing)成(cheng)堅硬的(de)(de)(de)涂膜(mo)。
