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(liao)，施工(gong)(gong)(gong)(gong)(gong)對環境對人體無毒害；涂(tu)層(ceng)外觀(guan)質量(liang)優異(yi)，附著力及機械(xie)強度強；噴(pen)(pen)(pen)(pen)涂(tu)施工(gong)(gong)(gong)(gong)(gong)固(gu)化時(shi)間(jian)短；涂(tu)層(ceng)耐腐耐磨能力高出(chu)很(hen)多；不(bu)(bu)需底漆(qi)；施工(gong)(gong)(gong)(gong)(gong)簡(jian)便，對工(gong)(gong)(gong)(gong)(gong)人技術(shu)要求低；成本低于(yu)噴(pen)(pen)(pen)(pen)漆(qi)工(gong)(gong)(gong)(gong)(gong)藝；有些施工(gong)(gong)(gong)(gong)(gong)場合已經明確(que)提出(chu)使用(yong)靜電噴(pen)(pen)(pen)(pen)塑工(gong)(gong)(gong)(gong)(gong)藝處理；靜電噴(pen)(pen)(pen)(pen)粉噴(pen)(pen)(pen)(pen)涂(tu)過程中不(bu)(bu)會出(chu)現(xian)噴(pen)(pen)(pen)(pen)漆(qi)工(gong)(gong)(gong)(gong)(gong)藝中常見的流淌現(xian)象。

是利用電(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象使(shi)粉(fen)末(mo)涂(tu)料吸(xi)附在(zai)電(dian)(dian)(dian)(dian)(dian)纜橋架上(shang)的(de)(de)(de)(de)(de)。其(qi)過程是這樣的(de)(de)(de)(de)(de)：粉(fen)末(mo)涂(tu)料由(you)供(gong)粉(fen)系(xi)統(tong)借壓縮空(kong)氣氣體(ti)送入噴槍，在(zai)噴槍前端加有高壓靜(jing)電(dian)(dian)(dian)(dian)(dian)發生(sheng)器產(chan)生(sheng)的(de)(de)(de)(de)(de)高壓，由(you)于電(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)，在(zai)其(qi)附近產(chan)生(sheng)密(mi)集的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)荷(he)，粉(fen)末(mo)由(you)槍嘴(zui)噴出(chu)時(shi)(shi)，形成(cheng)帶(dai)電(dian)(dian)(dian)(dian)(dian)涂(tu)料粒子，它受靜(jing)電(dian)(dian)(dian)(dian)(dian)力的(de)(de)(de)(de)(de)作用，被吸(xi)到(dao)與其(qi)相反的(de)(de)(de)(de)(de)工(gong)件(jian)上(shang)去，隨著噴上(shang)的(de)(de)(de)(de)(de)粉(fen)末(mo)增多，電(dian)(dian)(dian)(dian)(dian)荷(he)積聚(ju)也越多，當達(da)到(dao)一定(ding)厚度時(shi)(shi)，由(you)于產(chan)生(sheng)靜(jing)電(dian)(dian)(dian)(dian)(dian)排斥作用，便不(bu)繼(ji)續吸(xi)附，從而使(shi)整個工(gong)件(jian)獲得一定(ding)厚度的(de)(de)(de)(de)(de)粉(fen)末(mo)涂(tu)層(ceng)，然后經過熱使(shi)粉(fen)末(mo)熔融、流平、固化(hua)，即在(zai)工(gong)件(jian)表面形成(cheng)堅硬的(de)(de)(de)(de)(de)涂(tu)膜。
