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)對(dui)環境對(dui)人(ren)體無毒害；涂(tu)層外觀質(zhi)量優異，附(fu)著力及機械強(qiang)(qiang)度強(qiang)(qiang)；噴(pen)(pen)涂(tu)施工(gong)(gong)固化時(shi)間短；涂(tu)層耐腐耐磨能(neng)力高出很多；不需(xu)底漆(qi)；施工(gong)(gong)簡(jian)便(bian)，對(dui)工(gong)(gong)人(ren)技(ji)術要求低(di)；成本低(di)于噴(pen)(pen)漆(qi)工(gong)(gong)藝(yi)；有些施工(gong)(gong)場合已經明確提出使用靜(jing)電噴(pen)(pen)塑工(gong)(gong)藝(yi)處理；靜(jing)電噴(pen)(pen)粉噴(pen)(pen)涂(tu)過程中不會出現(xian)噴(pen)(pen)漆(qi)工(gong)(gong)藝(yi)中常見的流淌現(xian)象。

是利用電(dian)(dian)(dian)暈放電(dian)(dian)(dian)現象使(shi)粉(fen)(fen)(fen)末(mo)涂(tu)料(liao)吸(xi)附在電(dian)(dian)(dian)纜橋架上的。其過程是這樣(yang)的：粉(fen)(fen)(fen)末(mo)涂(tu)料(liao)由供粉(fen)(fen)(fen)系統借(jie)壓(ya)縮(suo)空(kong)氣氣體(ti)送入噴(pen)槍，在噴(pen)槍前端加(jia)有(you)高壓(ya)靜電(dian)(dian)(dian)發(fa)生(sheng)器產(chan)(chan)生(sheng)的高壓(ya)，由于(yu)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)，在其附近產(chan)(chan)生(sheng)密集的電(dian)(dian)(dian)荷，粉(fen)(fen)(fen)末(mo)由槍嘴噴(pen)出時，形(xing)成(cheng)帶電(dian)(dian)(dian)涂(tu)料(liao)粒(li)子，它受靜電(dian)(dian)(dian)力的作用，被吸(xi)到(dao)與(yu)其相反的工(gong)件上去(qu)，隨著噴(pen)上的粉(fen)(fen)(fen)末(mo)增多，電(dian)(dian)(dian)荷積聚也越(yue)多，當達到(dao)一定厚度(du)時，由于(yu)產(chan)(chan)生(sheng)靜電(dian)(dian)(dian)排斥作用，便不繼續(xu)吸(xi)附，從(cong)而使(shi)整(zheng)個工(gong)件獲得(de)一定厚度(du)的粉(fen)(fen)(fen)末(mo)涂(tu)層，然后經過熱(re)使(shi)粉(fen)(fen)(fen)末(mo)熔融、流(liu)平、固化，即(ji)在工(gong)件表面形(xing)成(cheng)堅硬的涂(tu)膜(mo)。
