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，施工(gong)(gong)(gong)(gong)對(dui)環境對(dui)人體無毒(du)害；涂(tu)(tu)層外觀質量優異，附著(zhu)力及機械強度強；噴(pen)(pen)涂(tu)(tu)施工(gong)(gong)(gong)(gong)固化時間短(duan)；涂(tu)(tu)層耐腐(fu)耐磨能(neng)力高出(chu)很多；不(bu)需底(di)漆；施工(gong)(gong)(gong)(gong)簡便，對(dui)工(gong)(gong)(gong)(gong)人技術要求(qiu)低(di)；成本(ben)低(di)于噴(pen)(pen)漆工(gong)(gong)(gong)(gong)藝(yi)；有些施工(gong)(gong)(gong)(gong)場合(he)已經明(ming)確提出(chu)使用(yong)靜電(dian)噴(pen)(pen)塑工(gong)(gong)(gong)(gong)藝(yi)處理；靜電(dian)噴(pen)(pen)粉(fen)噴(pen)(pen)涂(tu)(tu)過程中不(bu)會出(chu)現(xian)噴(pen)(pen)漆工(gong)(gong)(gong)(gong)藝(yi)中常見的流淌現(xian)象。

是利用電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)現象使(shi)粉(fen)末(mo)(mo)涂料吸附(fu)在電(dian)(dian)(dian)纜橋架(jia)上(shang)的(de)(de)(de)。其(qi)過(guo)程是這樣的(de)(de)(de)：粉(fen)末(mo)(mo)涂料由(you)供粉(fen)系統借壓(ya)縮空氣氣體送入噴(pen)槍(qiang)，在噴(pen)槍(qiang)前端加有高壓(ya)靜(jing)電(dian)(dian)(dian)發生(sheng)器產生(sheng)的(de)(de)(de)高壓(ya)，由(you)于電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)，在其(qi)附(fu)近(jin)產生(sheng)密(mi)集的(de)(de)(de)電(dian)(dian)(dian)荷，粉(fen)末(mo)(mo)由(you)槍(qiang)嘴噴(pen)出時，形成帶電(dian)(dian)(dian)涂料粒(li)子，它受靜(jing)電(dian)(dian)(dian)力的(de)(de)(de)作(zuo)用，被吸到與(yu)其(qi)相(xiang)反的(de)(de)(de)工(gong)(gong)件(jian)上(shang)去，隨著(zhu)噴(pen)上(shang)的(de)(de)(de)粉(fen)末(mo)(mo)增多(duo)，電(dian)(dian)(dian)荷積(ji)聚也越多(duo)，當達(da)到一定厚度時，由(you)于產生(sheng)靜(jing)電(dian)(dian)(dian)排斥作(zuo)用，便(bian)不(bu)繼續(xu)吸附(fu)，從而使(shi)整個工(gong)(gong)件(jian)獲得一定厚度的(de)(de)(de)粉(fen)末(mo)(mo)涂層(ceng)，然(ran)后經過(guo)熱使(shi)粉(fen)末(mo)(mo)熔融、流(liu)平、固化，即(ji)在工(gong)(gong)件(jian)表面形成堅硬的(de)(de)(de)涂膜。
