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(liao)，施(shi)工對(dui)環境對(dui)人體無毒害(hai)；涂(tu)(tu)層外觀質(zhi)量優異，附(fu)著力及機械強(qiang)度(du)強(qiang)；噴(pen)涂(tu)(tu)施(shi)工固化時間短；涂(tu)(tu)層耐腐耐磨能力高出(chu)很多；不需(xu)底漆；施(shi)工簡便，對(dui)工人技術要(yao)求低；成本低于噴(pen)漆工藝；有(you)些施(shi)工場(chang)合已經明確提出(chu)使用靜電(dian)噴(pen)塑工藝處理；靜電(dian)噴(pen)粉噴(pen)涂(tu)(tu)過(guo)程中(zhong)不會出(chu)現噴(pen)漆工藝中(zhong)常見(jian)的流淌現象。

是(shi)利用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象使粉末涂(tu)料吸附在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)纜橋架上的(de)(de)。其過程(cheng)是(shi)這樣(yang)的(de)(de)：粉末涂(tu)料由(you)供粉系(xi)統借壓縮空氣氣體送入噴(pen)槍，在(zai)噴(pen)槍前端加(jia)有高壓靜電(dian)(dian)(dian)(dian)(dian)(dian)發(fa)生(sheng)器產生(sheng)的(de)(de)高壓，由(you)于電(dian)(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，在(zai)其附近產生(sheng)密(mi)集的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷，粉末由(you)槍嘴噴(pen)出時(shi)(shi)，形(xing)成帶電(dian)(dian)(dian)(dian)(dian)(dian)涂(tu)料粒子(zi)，它受靜電(dian)(dian)(dian)(dian)(dian)(dian)力(li)的(de)(de)作(zuo)用(yong)，被吸到(dao)與其相(xiang)反的(de)(de)工(gong)(gong)件(jian)上去，隨著噴(pen)上的(de)(de)粉末增多(duo)，電(dian)(dian)(dian)(dian)(dian)(dian)荷積聚也(ye)越多(duo)，當達到(dao)一定厚度時(shi)(shi)，由(you)于產生(sheng)靜電(dian)(dian)(dian)(dian)(dian)(dian)排斥(chi)作(zuo)用(yong)，便不(bu)繼續吸附，從而使整個工(gong)(gong)件(jian)獲(huo)得一定厚度的(de)(de)粉末涂(tu)層，然后(hou)經過熱使粉末熔融、流平、固化，即在(zai)工(gong)(gong)件(jian)表面(mian)形(xing)成堅硬的(de)(de)涂(tu)膜(mo)。
