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，施工(gong)(gong)對(dui)(dui)環境對(dui)(dui)人(ren)體無毒害(hai)；涂(tu)層(ceng)外觀(guan)質量優異，附(fu)著力及機械強(qiang)度強(qiang)；噴(pen)涂(tu)施工(gong)(gong)固化時間短；涂(tu)層(ceng)耐(nai)腐(fu)耐(nai)磨能力高出很多；不(bu)需底(di)漆；施工(gong)(gong)簡便，對(dui)(dui)工(gong)(gong)人(ren)技術(shu)要求低；成本低于噴(pen)漆工(gong)(gong)藝(yi)；有些施工(gong)(gong)場合已(yi)經明確提出使用(yong)靜電(dian)噴(pen)塑工(gong)(gong)藝(yi)處理；靜電(dian)噴(pen)粉噴(pen)涂(tu)過程中不(bu)會出現噴(pen)漆工(gong)(gong)藝(yi)中常見的流(liu)淌(tang)現象(xiang)。

是利用(yong)電(dian)(dian)暈(yun)放電(dian)(dian)現象使(shi)粉(fen)(fen)末(mo)涂(tu)(tu)料吸附(fu)在(zai)電(dian)(dian)纜橋架上(shang)的(de)。其過程是這樣的(de)：粉(fen)(fen)末(mo)涂(tu)(tu)料由(you)供粉(fen)(fen)系統借壓縮空(kong)氣氣體送入(ru)噴槍(qiang)，在(zai)噴槍(qiang)前端(duan)加有高(gao)壓靜電(dian)(dian)發生(sheng)器(qi)產(chan)生(sheng)的(de)高(gao)壓，由(you)于電(dian)(dian)暈(yun)放電(dian)(dian)，在(zai)其附(fu)近產(chan)生(sheng)密集的(de)電(dian)(dian)荷(he)(he)，粉(fen)(fen)末(mo)由(you)槍(qiang)嘴(zui)噴出時(shi)，形(xing)成(cheng)帶電(dian)(dian)涂(tu)(tu)料粒(li)子，它受靜電(dian)(dian)力的(de)作用(yong)，被(bei)吸到與(yu)其相(xiang)反的(de)工(gong)(gong)件上(shang)去，隨(sui)著噴上(shang)的(de)粉(fen)(fen)末(mo)增(zeng)多，電(dian)(dian)荷(he)(he)積(ji)聚(ju)也越多，當達到一定厚(hou)度時(shi)，由(you)于產(chan)生(sheng)靜電(dian)(dian)排斥作用(yong)，便不(bu)繼續(xu)吸附(fu)，從而使(shi)整(zheng)個工(gong)(gong)件獲(huo)得一定厚(hou)度的(de)粉(fen)(fen)末(mo)涂(tu)(tu)層，然后(hou)經過熱使(shi)粉(fen)(fen)末(mo)熔(rong)融(rong)、流平、固化，即在(zai)工(gong)(gong)件表面形(xing)成(cheng)堅硬的(de)涂(tu)(tu)膜。
