style="text-indent:25px">螺紋硅碳管是一種非金屬的電熱元件，在很多的行業(yè)都有應(yīng)用到，而且該產(chǎn)品在使用的過(guò)程中是會(huì)發(fā)熱的，正因如此它根據(jù)這個(gè)原理進(jìn)行工作，下面就給大家介紹一下它的發(fā)熱原理：　　一、發(fā)熱原理　　1、在外加電能量作用下，電子和空穴的輻射復(fù)合發(fā)生電致發(fā)光，在PN結(jié)附近輻射出來(lái)的光還需經(jīng)過(guò)碳管本身的半導(dǎo)體介質(zhì)和封裝介質(zhì)才能抵達(dá)外界，比如空氣。　　2、綜合電流注入效率、輻射發(fā)光量子效率、碳管外部光取出效率等，之后大概只有60-70％的能量主要以非輻射復(fù)合發(fā)生的點(diǎn)陣振動(dòng)的形式轉(zhuǎn)化熱能。　　二、含義　　1、該產(chǎn)品是用高精度碳化硅，化學(xué)式是SIC為主要原料、經(jīng)高溫2200℃再結(jié)晶制成的非金屬電熱元件。　　2、使用中限度的高溫在1600℃，正常使用溫度1450攝氏度，連續(xù)使用壽命可達(dá)3000小時(shí)以上。　　螺紋硅碳管發(fā)熱原理很簡(jiǎn)單，不過(guò)我們?cè)谶M(jìn)行使用的時(shí)候也要掌控好它的溫度，不要超過(guò)限度，否則會(huì)因?yàn)檫^(guò)熱而給產(chǎn)品以及人員帶來(lái)傷害，除此之外，定期保養(yǎng)和維護(hù)，可以很好地提高工作性能和延長(zhǎng)使用期限。</p><p> 產(chǎn)品結(jié)構(gòu)本系列電爐外殼由鋼板卷制焊接而成，爐膛管采用耐高溫的氧化鋁制成。發(fā)熱元件為硅碳管，其外套有隔熱高鋁管，爐膛襯有絕熱良好的保溫材料。由于選用雙螺紋一端接線的硅碳管，與工作電源連接比較整齊方便，熱電偶也從此端插入。四、使用注意事項(xiàng)1、硅碳管質(zhì)地硬而脆，螺紋帶彈性有限，安裝拆卸時(shí)應(yīng)充分小心注意，以免折斷，碰壞。在任何情況下應(yīng)保證它自由膨脹和收縮，應(yīng)避免機(jī)械應(yīng)力的存在。2、硅碳管的老化、壽命與使用溫度關(guān)系很大，一般在1300℃±50℃能運(yùn)行1500作業(yè)小時(shí)左右。3、被加熱物不能含有過(guò)高的水分，否則會(huì)影響硅碳管的壽命，可以烘干以后再加熱。4、硅碳管不適應(yīng)在保護(hù)氣氛下工作，例如氫氣。一氧化碳在供氧不足的情況下也會(huì)使碳游離，從而影響硅碳管的壽命。5、硅碳管的表面負(fù)荷的選用隨溫度而變化，工作溫度在1300℃時(shí)允許6w/cm2，而工作溫度在1000℃時(shí)可允許30w/cm2，選擇合適的加熱功率可以延長(zhǎng)硅碳管的壽命。6、硅碳管安裝之前應(yīng)將內(nèi)外爐管之間打掃干凈。硅碳管螺紋帶之間或能引起短路的雜物，導(dǎo)電卡子連接片應(yīng)旋緊接實(shí)，絕緣片應(yīng)可靠絕緣。7、安裝完畢即可通電烘爐，由低溫小功率開(kāi)始進(jìn)行8小時(shí)，長(zhǎng)期不用使用前也必須烘爐，尤其是南方潮濕地區(qū)。奧翔硅碳以發(fā)展求壯大，就一定會(huì)贏得更好的明天。</p><div
