陶瓷圈

      陶(tao)瓷電熱(re)圈(quan)(quan)采(cai)用(yong)(yong)的不(bu)(bu)是(shi)一(yi)般云母撓線方式(shi)(shi)制作，而是(shi)采(cai)用(yong)(yong)陶(tao)瓷條穿絲方式(shi)(shi)，因此該產品(pin)的功率比(bi)普通(tong)的要高(gao)0.5~1.5倍(bei)。發(fa)熱(re)體(ti)為進(jin)口(kou)圓絲陶(tao)撓成彈簧狀(zhuang)穿入陶(tao)瓷條圈(quan)(quan)成,外(wai)罩采(cai)用(yong)(yong)日本產不(bu)(bu)銹鋼,中間采(cai)用(yong)(yong)高(gao)溫(wen)(wen)隔熱(re)保溫(wen)(wen)棉（硅酸鋁纖(xian)維板）防止溫(wen)(wen)度(du)外(wai)泄。陶(tao)瓷條是(shi)高(gao)頻陶(tao)瓷具有傳熱(re)快、堅硬(ying)不(bu)(bu)易碎、高(gao)溫(wen)(wen)不(bu)(bu)變(bian)形不(bu)(bu)易老化等優點。
