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)(bu)需稀料，施(shi)工(gong)對(dui)環(huan)境對(dui)人(ren)(ren)體(ti)無毒(du)害；涂(tu)層(ceng)外觀質(zhi)量優異，附著力及(ji)機(ji)械強度強；噴(pen)(pen)涂(tu)施(shi)工(gong)固化時間短(duan)；涂(tu)層(ceng)耐腐耐磨(mo)能力高出很(hen)多；不(bu)(bu)需底漆(qi)；施(shi)工(gong)簡(jian)便，對(dui)工(gong)人(ren)(ren)技(ji)術(shu)要求(qiu)低；成本低于(yu)噴(pen)(pen)漆(qi)工(gong)藝(yi)；有些(xie)施(shi)工(gong)場(chang)合已經明確提(ti)出使用(yong)靜電噴(pen)(pen)塑工(gong)藝(yi)處理；靜電噴(pen)(pen)粉噴(pen)(pen)涂(tu)過程中不(bu)(bu)會出現噴(pen)(pen)漆(qi)工(gong)藝(yi)中常見的(de)流淌現象。

是(shi)利用(yong)電(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)現(xian)象使(shi)(shi)(shi)粉(fen)(fen)末(mo)涂(tu)料(liao)吸附(fu)在電(dian)(dian)(dian)(dian)(dian)纜(lan)橋架上(shang)的(de)(de)(de)。其(qi)過程是(shi)這樣的(de)(de)(de)：粉(fen)(fen)末(mo)涂(tu)料(liao)由(you)(you)供粉(fen)(fen)系統借(jie)壓(ya)縮空氣(qi)(qi)氣(qi)(qi)體送入噴(pen)槍，在噴(pen)槍前端加有高壓(ya)靜電(dian)(dian)(dian)(dian)(dian)發生(sheng)(sheng)器產(chan)生(sheng)(sheng)的(de)(de)(de)高壓(ya)，由(you)(you)于電(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)，在其(qi)附(fu)近產(chan)生(sheng)(sheng)密集的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)荷，粉(fen)(fen)末(mo)由(you)(you)槍嘴噴(pen)出時，形成帶電(dian)(dian)(dian)(dian)(dian)涂(tu)料(liao)粒子，它受靜電(dian)(dian)(dian)(dian)(dian)力(li)的(de)(de)(de)作(zuo)用(yong)，被吸到與其(qi)相(xiang)反的(de)(de)(de)工(gong)件(jian)上(shang)去，隨著噴(pen)上(shang)的(de)(de)(de)粉(fen)(fen)末(mo)增多，電(dian)(dian)(dian)(dian)(dian)荷積聚也越(yue)多，當達到一定厚度時，由(you)(you)于產(chan)生(sheng)(sheng)靜電(dian)(dian)(dian)(dian)(dian)排斥(chi)作(zuo)用(yong)，便不繼續吸附(fu)，從(cong)而使(shi)(shi)(shi)整個工(gong)件(jian)獲(huo)得(de)一定厚度的(de)(de)(de)粉(fen)(fen)末(mo)涂(tu)層，然后(hou)經(jing)過熱(re)使(shi)(shi)(shi)粉(fen)(fen)末(mo)熔融、流平、固化，即(ji)在工(gong)件(jian)表面形成堅(jian)硬的(de)(de)(de)涂(tu)膜。
