陶瓷圈

      陶瓷電熱(re)圈采用(yong)(yong)的(de)不(bu)(bu)是一般云(yun)母撓線方(fang)式制作，而(er)是采用(yong)(yong)陶瓷條穿絲(si)方(fang)式，因(yin)此該(gai)產(chan)(chan)品的(de)功率比普通(tong)的(de)要高0.5~1.5倍。發熱(re)體為進(jin)口圓絲(si)陶撓成(cheng)(cheng)彈(dan)簧狀穿入陶瓷條圈成(cheng)(cheng),外(wai)(wai)罩采用(yong)(yong)日本產(chan)(chan)不(bu)(bu)銹鋼,中間采用(yong)(yong)高溫(wen)(wen)隔熱(re)保溫(wen)(wen)棉（硅(gui)酸鋁纖維(wei)板(ban)）防止溫(wen)(wen)度外(wai)(wai)泄。陶瓷條是高頻陶瓷具有傳熱(re)快、堅硬(ying)不(bu)(bu)易碎(sui)、高溫(wen)(wen)不(bu)(bu)變形(xing)不(bu)(bu)易老化等優點。
