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)(shi)工(gong)(gong)對環境對人體無毒害；涂(tu)(tu)層(ceng)外觀(guan)質量優異，附著(zhu)力及機械強(qiang)度強(qiang)；噴涂(tu)(tu)施(shi)(shi)工(gong)(gong)固化(hua)時間短(duan)；涂(tu)(tu)層(ceng)耐腐耐磨能(neng)力高出很(hen)多；不(bu)需底漆(qi)；施(shi)(shi)工(gong)(gong)簡便，對工(gong)(gong)人技術(shu)要(yao)求低；成(cheng)本(ben)低于噴漆(qi)工(gong)(gong)藝；有些施(shi)(shi)工(gong)(gong)場合已經明確(que)提出使(shi)用靜電噴塑工(gong)(gong)藝處(chu)理(li)；靜電噴粉噴涂(tu)(tu)過程(cheng)中(zhong)(zhong)不(bu)會出現噴漆(qi)工(gong)(gong)藝中(zhong)(zhong)常見的流淌(tang)現象。

是利用電(dian)(dian)暈(yun)放電(dian)(dian)現象使粉(fen)(fen)(fen)末(mo)涂(tu)(tu)料吸附在(zai)電(dian)(dian)纜(lan)橋(qiao)架上(shang)的(de)(de)。其過程是這樣(yang)的(de)(de)：粉(fen)(fen)(fen)末(mo)涂(tu)(tu)料由供(gong)粉(fen)(fen)(fen)系(xi)統(tong)借壓縮(suo)空氣氣體送(song)入噴(pen)(pen)槍，在(zai)噴(pen)(pen)槍前端加有高(gao)壓靜(jing)(jing)電(dian)(dian)發生器產(chan)生的(de)(de)高(gao)壓，由于電(dian)(dian)暈(yun)放電(dian)(dian)，在(zai)其附近產(chan)生密集的(de)(de)電(dian)(dian)荷，粉(fen)(fen)(fen)末(mo)由槍嘴噴(pen)(pen)出時，形成帶電(dian)(dian)涂(tu)(tu)料粒子，它受靜(jing)(jing)電(dian)(dian)力的(de)(de)作用，被吸到與其相反的(de)(de)工(gong)件(jian)上(shang)去(qu)，隨著噴(pen)(pen)上(shang)的(de)(de)粉(fen)(fen)(fen)末(mo)增多(duo)，電(dian)(dian)荷積聚也越(yue)多(duo)，當達到一(yi)定厚度時，由于產(chan)生靜(jing)(jing)電(dian)(dian)排(pai)斥作用，便不繼續吸附，從而使整個工(gong)件(jian)獲得一(yi)定厚度的(de)(de)粉(fen)(fen)(fen)末(mo)涂(tu)(tu)層，然后經(jing)過熱使粉(fen)(fen)(fen)末(mo)熔融、流(liu)平、固化，即在(zai)工(gong)件(jian)表面(mian)形成堅硬的(de)(de)涂(tu)(tu)膜。
