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。

不需稀(xi)料，施工(gong)(gong)(gong)對(dui)(dui)(dui)環境對(dui)(dui)(dui)人體(ti)無(wu)毒害(hai)；涂(tu)(tu)層外觀質量優異，附著力及機械強度強；噴涂(tu)(tu)施工(gong)(gong)(gong)固(gu)化時間短；涂(tu)(tu)層耐(nai)腐(fu)耐(nai)磨(mo)能(neng)力高出(chu)很(hen)多；不需底漆(qi)；施工(gong)(gong)(gong)簡便，對(dui)(dui)(dui)工(gong)(gong)(gong)人技(ji)術要(yao)求低；成本低于噴漆(qi)工(gong)(gong)(gong)藝；有些施工(gong)(gong)(gong)場合已經明確(que)提出(chu)使用靜電(dian)噴塑工(gong)(gong)(gong)藝處理；靜電(dian)噴粉噴涂(tu)(tu)過(guo)程(cheng)中不會出(chu)現噴漆(qi)工(gong)(gong)(gong)藝中常見的流淌現象。

是利用電(dian)(dian)暈放(fang)電(dian)(dian)現象使粉(fen)(fen)(fen)末(mo)涂(tu)料吸(xi)附(fu)在電(dian)(dian)纜(lan)橋架上的(de)(de)(de)。其過程是這樣的(de)(de)(de)：粉(fen)(fen)(fen)末(mo)涂(tu)料由(you)(you)供粉(fen)(fen)(fen)系(xi)統借壓縮空氣氣體送(song)入噴(pen)槍(qiang)，在噴(pen)槍(qiang)前端(duan)加有高壓靜(jing)電(dian)(dian)發生(sheng)器產生(sheng)的(de)(de)(de)高壓，由(you)(you)于電(dian)(dian)暈放(fang)電(dian)(dian)，在其附(fu)近(jin)產生(sheng)密集(ji)的(de)(de)(de)電(dian)(dian)荷(he)(he)，粉(fen)(fen)(fen)末(mo)由(you)(you)槍(qiang)嘴噴(pen)出時，形成帶電(dian)(dian)涂(tu)料粒(li)子，它受靜(jing)電(dian)(dian)力(li)的(de)(de)(de)作(zuo)用，被吸(xi)到與其相反(fan)的(de)(de)(de)工(gong)件上去，隨(sui)著(zhu)噴(pen)上的(de)(de)(de)粉(fen)(fen)(fen)末(mo)增多，電(dian)(dian)荷(he)(he)積聚也越多，當(dang)達到一定(ding)(ding)厚度時，由(you)(you)于產生(sheng)靜(jing)電(dian)(dian)排(pai)斥作(zuo)用，便不繼續吸(xi)附(fu)，從(cong)而使整個工(gong)件獲(huo)得(de)一定(ding)(ding)厚度的(de)(de)(de)粉(fen)(fen)(fen)末(mo)涂(tu)層(ceng)，然后經過熱使粉(fen)(fen)(fen)末(mo)熔融、流平(ping)、固化，即在工(gong)件表面(mian)形成堅硬(ying)的(de)(de)(de)涂(tu)膜。
