等直徑硅碳棒“老化”的原因是什么呢？1小編就為大家介紹一下硅碳棒的“老化”。硅碳棒是由于在高溫下,空氣中的o2、co2和水蒸汽能強(qiáng)烈地促使砝碳櫸氧化，生成玻璃態(tài)的Sio2薄膜，而Si02的電阻率較SiC電PU率大，故使電阻增加。又因?yàn)檫@層SiO,薄暌可以保護(hù)內(nèi)層的Sic不再繼續(xù)氧化，所以在連續(xù)使用一定時(shí)間后，電阻的增加將緩慢下來(lái)。在間歇使用時(shí)，由干sio2薄膜與SiC的熱膨脹系數(shù)不同，當(dāng)砝碳棒冷卻時(shí)，這層玻璃態(tài)薄膜即行破裂而暴露出新的Sic表面。當(dāng)繼續(xù)加熱時(shí)，這些新露出的SiC表面又繼續(xù)被氧化，經(jīng)過(guò)多次加熱、冷卻之后丨珪碳棒的電阻越來(lái)越大，終千大到不能再使用了。1、幾何尺寸的選擇電爐的爐膛是由被加熱物的尺寸推算而決定，因而硅碳管的尺寸也相應(yīng)確定下來(lái)，現(xiàn)舉例說(shuō)明如下：如被加熱物是?70×500mm的石英管（這里的500mm是指石英管的受熱區(qū)，實(shí)際上石英管還要長(zhǎng)）則硅碳管的規(guī)格可選用?90/80×500/100，重慶專業(yè)生產(chǎn)硅碳管供應(yīng)商，二爐膛的高鋁管則可選用其內(nèi)徑為100mm，其長(zhǎng)度要略長(zhǎng)于500mm。2、硅碳棒保護(hù)管使用的功率硅碳管使用的功率決定于爐子的保溫條件，幾何尺寸及到達(dá)的溫度。對(duì)于較好的保溫條件，恒溫后，重慶專業(yè)生產(chǎn)硅碳管供應(yīng)商，硅碳管發(fā)熱區(qū)內(nèi)表面的溫度與被加熱物的溫度相差≦50℃，重慶專業(yè)生產(chǎn)硅碳管供應(yīng)商。奧翔硅碳技術(shù)力量雄厚，工裝設(shè)備和檢測(cè)儀器齊備，檢驗(yàn)與實(shí)驗(yàn)手段完善。重慶專業(yè)生產(chǎn)硅碳管供應(yīng)商</p><div

粗端式硅碳棒在高溫下長(zhǎng)期使用，由于sic表面被氧化，致使原件中的sio2含量逐漸增多，使其電阻增大，這是正?，F(xiàn)象，稱之為“老化”，原件在使用中，前500小時(shí)老化速度快，以后的老化速度緩慢，主要是元件表面的sio2膜減緩了sic的氧化。硅碳棒的老化速度取決于元件的使用溫度和表面負(fù)荷密度。要想使硅碳棒的功率恒定不變，仍然獲得理想的爐溫，必須采用相應(yīng)的調(diào)壓器，適應(yīng)元件在使用中電阻增長(zhǎng)的需要。1、幾何尺寸的選擇電爐的爐膛是由被加熱物的尺寸推算而決定，因而硅碳管的尺寸也相應(yīng)確定下來(lái)，現(xiàn)舉例說(shuō)明如下：如被加熱物是?70×500mm的石英管（這里的500mm是指石英管的受熱區(qū)，實(shí)際上石英管還要長(zhǎng)）則硅碳管的規(guī)格可選用?90/80×500/100，二爐膛的高鋁管則可選用其內(nèi)徑為100mm，其長(zhǎng)度要略長(zhǎng)于500mm。2、硅碳棒保護(hù)管使用的功率硅碳管使用的功率決定于爐子的保溫條件，幾何尺寸及到達(dá)的溫度。對(duì)于較好的保溫條件，恒溫后，硅碳管發(fā)熱區(qū)內(nèi)表面的溫度與被加熱物的溫度相差≦50℃。我們可以利用下式先計(jì)算硅碳管發(fā)熱部單位表面積的負(fù)荷。奧翔硅碳以發(fā)展求壯大，就一定會(huì)贏得更好的明天。重慶專業(yè)生產(chǎn)硅碳管供應(yīng)商</p><p
