微弧氧(yang)化手電解質溶液(ye)及其組分的影(ying)響

微(wei)(wei)(wei)(wei)弧(hu)(hu)氧(yang)(yang)化(hua)(hua)電(dian)(dian)解液(ye)(ye)是獲到(dao)合格膜層的(de)技術(shu)關鍵(jian)。不同(tong)(tong)的(de)電(dian)(dian)解液(ye)(ye)成(cheng)(cheng)(cheng)分及氧(yang)(yang)化(hua)(hua)工(gong)藝參數，所(suo)得(de)膜層的(de)性質(zhi)也不同(tong)(tong)。微(wei)(wei)(wei)(wei)弧(hu)(hu)氧(yang)(yang)化(hua)(hua)電(dian)(dian)解液(ye)(ye)多采用含有一定金屬或非金屬氧(yang)(yang)化(hua)(hua)物堿性鹽(yan)(yan)溶(rong)液(ye)(ye)（如硅酸鹽(yan)(yan)、磷(lin)酸鹽(yan)(yan)、硼酸鹽(yan)(yan)等），微(wei)(wei)(wei)(wei)弧(hu)(hu)氧(yang)(yang)化(hua)(hua)電(dian)(dian)源(yuan)廠商，其在溶(rong)液(ye)(ye)中的(de)存在形式較好是膠體(ti)狀(zhuang)態。溶(rong)液(ye)(ye)的(de)pH范圍一般在9～13之(zhi)間。根據(ju)膜層性質(zhi)的(de)需(xu)要(yao)，微(wei)(wei)(wei)(wei)弧(hu)(hu)氧(yang)(yang)化(hua)(hua)電(dian)(dian)源(yuan)監控，可(ke)添加(jia)一些有機或無機鹽(yan)(yan)類作為輔(fu)助添加(jia)劑。在相同(tong)(tong)的(de)微(wei)(wei)(wei)(wei)弧(hu)(hu)電(dian)(dian)解電(dian)(dian)壓下，電(dian)(dian)解質(zhi)濃度(du)越大，成(cheng)(cheng)(cheng)膜速(su)度(du)就越快，微(wei)(wei)(wei)(wei)弧(hu)(hu)氧(yang)(yang)化(hua)(hua)電(dian)(dian)源(yuan)，溶(rong)液(ye)(ye)溫度(du)上升越慢(man)，反之(zhi)，成(cheng)(cheng)(cheng)膜速(su)度(du)較慢(man)，溶(rong)液(ye)(ye)溫度(du)上升較快。微(wei)(wei)(wei)(wei)弧(hu)(hu)氧(yang)(yang)化(hua)(hua)生產線、微(wei)(wei)(wei)(wei)弧(hu)(hu)氧(yang)(yang)化(hua)(hua)電(dian)(dian)源(yuan)
