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)對環境對人(ren)體無(wu)毒害；涂(tu)層(ceng)外觀質量優(you)異，附著(zhu)力及機械(xie)強(qiang)(qiang)度強(qiang)(qiang)；噴(pen)涂(tu)施工(gong)(gong)固化時間短；涂(tu)層(ceng)耐腐(fu)耐磨能力高出很多(duo)；不需(xu)底漆(qi)；施工(gong)(gong)簡(jian)便(bian)，對工(gong)(gong)人(ren)技(ji)術(shu)要求低(di)；成本低(di)于噴(pen)漆(qi)工(gong)(gong)藝；有些(xie)施工(gong)(gong)場合已經(jing)明確提出使用(yong)靜電噴(pen)塑工(gong)(gong)藝處理；靜電噴(pen)粉(fen)噴(pen)涂(tu)過程中不會出現噴(pen)漆(qi)工(gong)(gong)藝中常見的流淌現象。

是利用電(dian)(dian)暈放(fang)電(dian)(dian)現(xian)象使(shi)粉末(mo)(mo)涂(tu)(tu)料(liao)吸(xi)附(fu)在(zai)(zai)電(dian)(dian)纜橋架上的(de)。其過程是這樣的(de)：粉末(mo)(mo)涂(tu)(tu)料(liao)由(you)供(gong)粉系統借壓縮空氣氣體送(song)入噴槍，在(zai)(zai)噴槍前端加有高(gao)壓靜電(dian)(dian)發生(sheng)(sheng)器產(chan)生(sheng)(sheng)的(de)高(gao)壓，由(you)于(yu)電(dian)(dian)暈放(fang)電(dian)(dian)，在(zai)(zai)其附(fu)近產(chan)生(sheng)(sheng)密集的(de)電(dian)(dian)荷，粉末(mo)(mo)由(you)槍嘴噴出時，形(xing)成帶電(dian)(dian)涂(tu)(tu)料(liao)粒(li)子，它受靜電(dian)(dian)力的(de)作用，被(bei)吸(xi)到與其相反的(de)工件(jian)上去，隨著噴上的(de)粉末(mo)(mo)增(zeng)多，電(dian)(dian)荷積(ji)聚也越多，當達到一定厚(hou)度時，由(you)于(yu)產(chan)生(sheng)(sheng)靜電(dian)(dian)排斥作用，便不繼續吸(xi)附(fu)，從而使(shi)整個工件(jian)獲得一定厚(hou)度的(de)粉末(mo)(mo)涂(tu)(tu)層，然(ran)后經過熱使(shi)粉末(mo)(mo)熔融、流(liu)平、固化，即在(zai)(zai)工件(jian)表面形(xing)成堅硬的(de)涂(tu)(tu)膜。
