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，施工(gong)(gong)對環境(jing)對人體(ti)無毒害；涂層(ceng)外觀質量優異，附著力及(ji)機械強(qiang)度強(qiang)；噴(pen)(pen)(pen)涂施工(gong)(gong)固化(hua)時間短；涂層(ceng)耐腐耐磨能(neng)力高出(chu)很(hen)多；不(bu)(bu)需底(di)漆；施工(gong)(gong)簡(jian)便，對工(gong)(gong)人技術要求低；成本低于噴(pen)(pen)(pen)漆工(gong)(gong)藝(yi)；有些施工(gong)(gong)場合已(yi)經明確(que)提出(chu)使用(yong)靜電噴(pen)(pen)(pen)塑工(gong)(gong)藝(yi)處理；靜電噴(pen)(pen)(pen)粉噴(pen)(pen)(pen)涂過(guo)程中(zhong)不(bu)(bu)會出(chu)現噴(pen)(pen)(pen)漆工(gong)(gong)藝(yi)中(zhong)常(chang)見的流淌現象。

是利用電(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)現象使粉(fen)末(mo)(mo)涂料吸(xi)附在(zai)電(dian)(dian)(dian)(dian)纜橋(qiao)架上(shang)的(de)。其(qi)(qi)過程是這樣的(de)：粉(fen)末(mo)(mo)涂料由(you)供粉(fen)系(xi)統借壓縮空氣氣體送入噴(pen)槍(qiang)(qiang)，在(zai)噴(pen)槍(qiang)(qiang)前端加有(you)高壓靜電(dian)(dian)(dian)(dian)發生器產(chan)生的(de)高壓，由(you)于電(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)，在(zai)其(qi)(qi)附近(jin)產(chan)生密集(ji)的(de)電(dian)(dian)(dian)(dian)荷(he)，粉(fen)末(mo)(mo)由(you)槍(qiang)(qiang)嘴噴(pen)出時(shi)，形(xing)成帶電(dian)(dian)(dian)(dian)涂料粒子，它受靜電(dian)(dian)(dian)(dian)力的(de)作(zuo)用，被吸(xi)到與其(qi)(qi)相反的(de)工(gong)(gong)件(jian)上(shang)去，隨著噴(pen)上(shang)的(de)粉(fen)末(mo)(mo)增多，電(dian)(dian)(dian)(dian)荷(he)積聚也越多，當達到一定厚度(du)時(shi)，由(you)于產(chan)生靜電(dian)(dian)(dian)(dian)排斥作(zuo)用，便不繼續吸(xi)附，從而使整個工(gong)(gong)件(jian)獲(huo)得一定厚度(du)的(de)粉(fen)末(mo)(mo)涂層，然后經過熱使粉(fen)末(mo)(mo)熔融、流平(ping)、固化(hua)，即在(zai)工(gong)(gong)件(jian)表面形(xing)成堅(jian)硬的(de)涂膜。
