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(shi)工(gong)對環境對人體(ti)無毒(du)害；涂層外觀質量優異，附著力(li)及機械強度強；噴(pen)(pen)(pen)涂施(shi)工(gong)固化時(shi)間短；涂層耐腐耐磨能力(li)高(gao)出很多；不(bu)需底漆(qi)；施(shi)工(gong)簡(jian)便，對工(gong)人技(ji)術要求低(di)；成本低(di)于(yu)噴(pen)(pen)(pen)漆(qi)工(gong)藝；有些施(shi)工(gong)場合已經明確提出使(shi)用靜電噴(pen)(pen)(pen)塑工(gong)藝處理；靜電噴(pen)(pen)(pen)粉(fen)噴(pen)(pen)(pen)涂過(guo)程中不(bu)會出現噴(pen)(pen)(pen)漆(qi)工(gong)藝中常(chang)見的流淌(tang)現象(xiang)。

是利用電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)現象(xiang)使粉末(mo)涂(tu)(tu)(tu)料吸(xi)附(fu)在電(dian)(dian)(dian)纜橋(qiao)架上(shang)的(de)(de)(de)。其過(guo)程是這樣的(de)(de)(de)：粉末(mo)涂(tu)(tu)(tu)料由(you)供粉系統借壓(ya)縮空(kong)氣(qi)氣(qi)體(ti)送入噴(pen)槍，在噴(pen)槍前端加(jia)有(you)高(gao)壓(ya)靜電(dian)(dian)(dian)發(fa)生器(qi)產(chan)生的(de)(de)(de)高(gao)壓(ya)，由(you)于電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)，在其附(fu)近產(chan)生密(mi)集的(de)(de)(de)電(dian)(dian)(dian)荷，粉末(mo)由(you)槍嘴噴(pen)出時(shi)，形成帶(dai)電(dian)(dian)(dian)涂(tu)(tu)(tu)料粒子，它(ta)受靜電(dian)(dian)(dian)力的(de)(de)(de)作用，被(bei)吸(xi)到與其相反(fan)的(de)(de)(de)工件(jian)上(shang)去，隨著噴(pen)上(shang)的(de)(de)(de)粉末(mo)增多(duo)，電(dian)(dian)(dian)荷積聚也越多(duo)，當達到一定厚(hou)度時(shi)，由(you)于產(chan)生靜電(dian)(dian)(dian)排斥作用，便不繼續(xu)吸(xi)附(fu)，從而使整個工件(jian)獲得一定厚(hou)度的(de)(de)(de)粉末(mo)涂(tu)(tu)(tu)層，然(ran)后經過(guo)熱使粉末(mo)熔融、流平(ping)、固(gu)化，即在工件(jian)表面形成堅硬的(de)(de)(de)涂(tu)(tu)(tu)膜。
