  真空燒結爐(lu)是如何改善陶瓷(ci)材(cai)料性能的(de)

  真空燒結爐是(shi)將具有(you)特定(ding)化學(xue)成分和物(wu)理功用(yong)的材(cai)料(liao)轉變(bian)成特定(ding)結(jie)構(gou)的陶瓷(ci)材(cai)料(liao),使之在高(gao)真空(kong)條件(jian)下燒結(jie)。傳統上用(yong)真空(kong)燒結(jie)來取得(de)高(gao)溫高(gao)質(zhi)量的制品(pin)(pin),但因為高(gao)溫下燒結(jie)產生氣(qi)孔、裂紋、夾渣、組織疏松等(deng)缺陷。為了戰勝(sheng)傳統燒結(jie)過程中(zhong)的這(zhe)些缺陷,人們(men)通過改變(bian)燒結(jie)氣(qi)氛進(jin)行實驗,并不(bu)斷(duan)改善工(gong)藝來取得(de)具有(you)優良功用(yong)的陶瓷(ci)制品(pin)(pin)。

  真空燒(shao)結爐的真空輔佐加(jia)熱技能(neng)可以提高(gao)樣品在高(gao)溫下的質(zhi)量穩定(ding)性(xing)(xing),且(qie)在改善材料功用與質(zhi)量穩定(ding)性(xing)(xing)方面作(zuo)用明顯(xian),尤其是對一些(xie)高(gao)溫條件下構(gou)(gou)成晶粒細微、細密組織或結構(gou)(gou)愈(yu)加(jia)明顯(xian)。

  真空燒結爐的保養,一般(ban)包含(han)以(yi)下幾點:

  1、操作前首先查看爐體的真(zhen)空度(du),當爐體的真(zhen)空度(du)計顯現(xian)為0.12Pa~0.3Pa時,即可投入作業;

  2、當爐內的(de)作業溫(wen)度抵(di)達(da)300℃以上時,請(qing)使用不銹鋼(gang)加熱器以確(que)保爐體的(de)安全性(xing);

  3、為避免爐內產生過多水蒸氣(qi)影響(xiang)其散熱作用(yong),主張(zhang)選用(yong)空氣(qi)加熱器進行加熱;

  4、因為(wei)真空(kong)燒(shao)結(jie)爐的(de)作業環境比較惡劣(溫度高(gao)達500℃以上),為(wei)了確(que)保其正常運轉和延伸其使(shi)用(yong)壽命,主張您每(mei)半年對真空(kong)燒(shao)結(jie)爐進行(xing)一次(ci)全方面的(de)保護(hu)保養作業。
