攪拌站水加熱器將電能有效轉化為管道加熱器的遠紅外輻射能,管道加熱器直接傳遞給被烘干物,管道加熱器迅速轉化為分子熱運動,管道加熱器由內向外干燥,管道加熱器達到快速烘干定型的目的,并取得管道加熱器的顯著節能效果。
管道(dao)加熱(re)(re)(re)器(qi)(qi)(qi)的碳(tan)化(hua)(hua)硅遠(yuan)紅外(wai)(wai)電(dian)(dian)(dian)熱(re)(re)(re)板是用管道(dao)加熱(re)(re)(re)器(qi)(qi)(qi)的涂有金屬氧(yang)化(hua)(hua)物(wu)即遠(yuan)紅外(wai)(wai)線涂料(liao)的碳(tan)化(hua)(hua)硅板做輻射元件,管道(dao)加熱(re)(re)(re)器(qi)(qi)(qi)的在(zai)(zai)元件孔(kong)內(nei)(或槽內(nei))裝(zhuang)進電(dian)(dian)(dian)熱(re)(re)(re)絲,在(zai)(zai)管道(dao)加熱(re)(re)(re)器(qi)(qi)(qi)的元件的底部放有較厚的絕緣、耐火、隔熱(re)(re)(re)材料(liao),然后裝(zhuang)上管道(dao)加熱(re)(re)(re)器(qi)(qi)(qi)的金屬外(wai)(wai)殼,安裝(zhuang)好管道(dao)加熱(re)(re)(re)器(qi)(qi)(qi)的接線柱便可通電(dian)(dian)(dian)使(shi)用。管道(dao)加熱(re)(re)(re)器(qi)(qi)(qi)中的碳(tan)化(hua)(hua)硅常溫抗折(zhe)強(qiang)(qiang)度 45Mpa,1000 ℃高溫抗折(zhe)強(qiang)(qiang)度 50Mpa 管道(dao)加熱(re)(re)(re)器(qi)(qi)(qi)的體積密度2.7-2.75g/cm3,900℃熱(re)(re)(re)膨脹率0.42-0.48% 導熱(re)(re)(re)系數(350℃)10.3-16.7w/m.k 。
