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)(gong)對環境(jing)對人(ren)體無毒害；涂(tu)(tu)層外觀質量(liang)優異，附著力(li)及機械強(qiang)度強(qiang)；噴(pen)(pen)涂(tu)(tu)施(shi)工(gong)(gong)固化時(shi)間短；涂(tu)(tu)層耐腐耐磨能力(li)高(gao)出(chu)很多；不(bu)需底(di)漆；施(shi)工(gong)(gong)簡便，對工(gong)(gong)人(ren)技(ji)術(shu)要求(qiu)低；成本低于(yu)噴(pen)(pen)漆工(gong)(gong)藝；有些施(shi)工(gong)(gong)場合已經明確(que)提出(chu)使用靜(jing)電噴(pen)(pen)塑工(gong)(gong)藝處理；靜(jing)電噴(pen)(pen)粉噴(pen)(pen)涂(tu)(tu)過程中不(bu)會出(chu)現(xian)噴(pen)(pen)漆工(gong)(gong)藝中常(chang)見(jian)的(de)流淌現(xian)象。

是利用電(dian)(dian)(dian)暈放電(dian)(dian)(dian)現象使粉(fen)(fen)末(mo)(mo)涂(tu)料吸(xi)附在(zai)電(dian)(dian)(dian)纜橋架上的(de)(de)(de)(de)(de)。其(qi)過程(cheng)是這樣的(de)(de)(de)(de)(de)：粉(fen)(fen)末(mo)(mo)涂(tu)料由(you)供粉(fen)(fen)系統(tong)借壓(ya)縮空氣氣體(ti)送入(ru)噴(pen)槍，在(zai)噴(pen)槍前端加有(you)高壓(ya)靜電(dian)(dian)(dian)發生(sheng)器產生(sheng)的(de)(de)(de)(de)(de)高壓(ya)，由(you)于(yu)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)，在(zai)其(qi)附近產生(sheng)密集(ji)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)荷，粉(fen)(fen)末(mo)(mo)由(you)槍嘴(zui)噴(pen)出時，形成帶電(dian)(dian)(dian)涂(tu)料粒子，它受(shou)靜電(dian)(dian)(dian)力(li)的(de)(de)(de)(de)(de)作用，被吸(xi)到(dao)與其(qi)相(xiang)反的(de)(de)(de)(de)(de)工(gong)件(jian)上去(qu)，隨著(zhu)噴(pen)上的(de)(de)(de)(de)(de)粉(fen)(fen)末(mo)(mo)增多(duo)，電(dian)(dian)(dian)荷積(ji)聚也越多(duo)，當達到(dao)一定厚度(du)時，由(you)于(yu)產生(sheng)靜電(dian)(dian)(dian)排斥(chi)作用，便(bian)不(bu)繼續吸(xi)附，從(cong)而使整個工(gong)件(jian)獲得(de)一定厚度(du)的(de)(de)(de)(de)(de)粉(fen)(fen)末(mo)(mo)涂(tu)層，然后經過熱(re)使粉(fen)(fen)末(mo)(mo)熔融、流平(ping)、固(gu)化，即在(zai)工(gong)件(jian)表面形成堅硬的(de)(de)(de)(de)(de)涂(tu)膜。
