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)(gong)對環(huan)境對人體無毒害(hai)；涂層外觀質(zhi)量優異，附著(zhu)力及機械強度強；噴涂施(shi)工(gong)(gong)(gong)固化時間短；涂層耐腐耐磨能力高出(chu)(chu)很多；不(bu)需底漆；施(shi)工(gong)(gong)(gong)簡便，對工(gong)(gong)(gong)人技術要求低(di)；成本低(di)于噴漆工(gong)(gong)(gong)藝；有些施(shi)工(gong)(gong)(gong)場(chang)合已經(jing)明確提(ti)出(chu)(chu)使用靜電噴塑工(gong)(gong)(gong)藝處理；靜電噴粉(fen)噴涂過程中(zhong)(zhong)不(bu)會出(chu)(chu)現噴漆工(gong)(gong)(gong)藝中(zhong)(zhong)常見的流淌現象。

是利用(yong)電(dian)(dian)暈(yun)放電(dian)(dian)現象(xiang)使粉(fen)末涂(tu)料(liao)吸(xi)附在電(dian)(dian)纜橋架(jia)上的(de)(de)(de)。其過程是這樣的(de)(de)(de)：粉(fen)末涂(tu)料(liao)由(you)(you)供粉(fen)系統借(jie)壓縮空氣氣體送入噴(pen)(pen)槍，在噴(pen)(pen)槍前端加有高壓靜電(dian)(dian)發生(sheng)器產生(sheng)的(de)(de)(de)高壓，由(you)(you)于電(dian)(dian)暈(yun)放電(dian)(dian)，在其附近產生(sheng)密(mi)集的(de)(de)(de)電(dian)(dian)荷，粉(fen)末由(you)(you)槍嘴噴(pen)(pen)出時，形(xing)成帶電(dian)(dian)涂(tu)料(liao)粒(li)子，它受靜電(dian)(dian)力的(de)(de)(de)作用(yong)，被吸(xi)到與其相反的(de)(de)(de)工(gong)(gong)件上去(qu)，隨(sui)著噴(pen)(pen)上的(de)(de)(de)粉(fen)末增多(duo)，電(dian)(dian)荷積聚(ju)也越多(duo)，當達到一(yi)定(ding)厚度時，由(you)(you)于產生(sheng)靜電(dian)(dian)排斥(chi)作用(yong)，便不繼續(xu)吸(xi)附，從而使整(zheng)個(ge)工(gong)(gong)件獲得(de)一(yi)定(ding)厚度的(de)(de)(de)粉(fen)末涂(tu)層，然(ran)后經過熱使粉(fen)末熔融(rong)、流平、固化，即在工(gong)(gong)件表面形(xing)成堅硬(ying)的(de)(de)(de)涂(tu)膜(mo)。
