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(dui)(dui)環境(jing)對(dui)(dui)人(ren)體無(wu)毒(du)害(hai)；涂層外觀質量優異，附(fu)著力及(ji)機械(xie)強度強；噴(pen)(pen)(pen)涂施(shi)工(gong)(gong)固化(hua)時間短；涂層耐(nai)腐(fu)耐(nai)磨能力高出很(hen)多；不(bu)需底漆(qi)(qi)；施(shi)工(gong)(gong)簡(jian)便，對(dui)(dui)工(gong)(gong)人(ren)技(ji)術(shu)要(yao)求低(di)；成(cheng)本低(di)于噴(pen)(pen)(pen)漆(qi)(qi)工(gong)(gong)藝(yi)；有些施(shi)工(gong)(gong)場合已經明確提出使(shi)用靜(jing)電(dian)噴(pen)(pen)(pen)塑工(gong)(gong)藝(yi)處理；靜(jing)電(dian)噴(pen)(pen)(pen)粉噴(pen)(pen)(pen)涂過程中不(bu)會出現噴(pen)(pen)(pen)漆(qi)(qi)工(gong)(gong)藝(yi)中常見(jian)的流(liu)淌現象。

是利用電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)現象使粉(fen)末(mo)涂(tu)料吸(xi)附(fu)(fu)在電(dian)(dian)(dian)纜橋架上(shang)的(de)(de)。其過程是這樣的(de)(de)：粉(fen)末(mo)涂(tu)料由供粉(fen)系統借壓縮空氣氣體送入噴槍，在噴槍前端加有高壓靜(jing)電(dian)(dian)(dian)發生器產生的(de)(de)高壓，由于(yu)電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)，在其附(fu)(fu)近產生密(mi)集的(de)(de)電(dian)(dian)(dian)荷，粉(fen)末(mo)由槍嘴噴出(chu)時(shi)，形(xing)成(cheng)帶電(dian)(dian)(dian)涂(tu)料粒子(zi)，它(ta)受靜(jing)電(dian)(dian)(dian)力的(de)(de)作用，被吸(xi)到(dao)與(yu)其相反的(de)(de)工(gong)(gong)件上(shang)去，隨著(zhu)噴上(shang)的(de)(de)粉(fen)末(mo)增多，電(dian)(dian)(dian)荷積(ji)聚(ju)也(ye)越多，當達到(dao)一定厚度時(shi)，由于(yu)產生靜(jing)電(dian)(dian)(dian)排斥作用，便(bian)不繼續(xu)吸(xi)附(fu)(fu)，從而使整個工(gong)(gong)件獲得一定厚度的(de)(de)粉(fen)末(mo)涂(tu)層，然(ran)后經過熱使粉(fen)末(mo)熔融(rong)、流平、固(gu)化，即在工(gong)(gong)件表面(mian)形(xing)成(cheng)堅硬的(de)(de)涂(tu)膜。
