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(xi)料，施(shi)工(gong)(gong)對(dui)環境(jing)對(dui)人體(ti)無毒害(hai)；涂(tu)(tu)層外觀(guan)質量優異(yi)，附(fu)著力(li)及機械強度強；噴(pen)(pen)涂(tu)(tu)施(shi)工(gong)(gong)固化時(shi)間短；涂(tu)(tu)層耐腐(fu)耐磨能力(li)高出(chu)(chu)很多(duo)；不需(xu)底(di)漆(qi)；施(shi)工(gong)(gong)簡便，對(dui)工(gong)(gong)人技術要求低；成本(ben)低于噴(pen)(pen)漆(qi)工(gong)(gong)藝(yi)(yi)；有些施(shi)工(gong)(gong)場合已經明(ming)確提(ti)出(chu)(chu)使(shi)用靜電噴(pen)(pen)塑(su)工(gong)(gong)藝(yi)(yi)處理；靜電噴(pen)(pen)粉(fen)噴(pen)(pen)涂(tu)(tu)過程中(zhong)不會出(chu)(chu)現噴(pen)(pen)漆(qi)工(gong)(gong)藝(yi)(yi)中(zhong)常見(jian)的流淌(tang)現象。

是(shi)利用(yong)電(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)現象(xiang)使(shi)粉(fen)末(mo)涂(tu)料吸(xi)附(fu)(fu)在電(dian)(dian)(dian)(dian)纜橋(qiao)架上的。其(qi)(qi)(qi)過程是(shi)這樣的：粉(fen)末(mo)涂(tu)料由供粉(fen)系統借壓縮空氣氣體送入(ru)噴(pen)槍，在噴(pen)槍前端加有(you)高(gao)壓靜(jing)電(dian)(dian)(dian)(dian)發生器產(chan)(chan)生的高(gao)壓，由于(yu)電(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)，在其(qi)(qi)(qi)附(fu)(fu)近產(chan)(chan)生密集的電(dian)(dian)(dian)(dian)荷(he)，粉(fen)末(mo)由槍嘴噴(pen)出時(shi)，形成帶電(dian)(dian)(dian)(dian)涂(tu)料粒子，它受靜(jing)電(dian)(dian)(dian)(dian)力的作用(yong)，被(bei)吸(xi)到(dao)與其(qi)(qi)(qi)相反(fan)的工件(jian)上去，隨著噴(pen)上的粉(fen)末(mo)增多，電(dian)(dian)(dian)(dian)荷(he)積聚(ju)也越多，當達到(dao)一(yi)定厚度時(shi)，由于(yu)產(chan)(chan)生靜(jing)電(dian)(dian)(dian)(dian)排斥(chi)作用(yong)，便(bian)不繼續吸(xi)附(fu)(fu)，從而使(shi)整(zheng)個工件(jian)獲得(de)一(yi)定厚度的粉(fen)末(mo)涂(tu)層，然后經過熱使(shi)粉(fen)末(mo)熔融、流平、固(gu)化，即在工件(jian)表面形成堅硬的涂(tu)膜(mo)。
