真空燒結爐的優勢有哪些呢

  真(zhen)空(kong)(kong)燒(shao)(shao)(shao)結(jie)(jie)爐的(de)(de)(de)(de)(de)優(you)勢有(you)哪些(xie)(xie)呢  真(zhen)空(kong)(kong)燒(shao)(shao)(shao)結(jie)(jie)爐的(de)(de)(de)(de)(de)優(you)勢有(you)哪些(xie)(xie)呢?這次八佳小編就和(he)大家介紹下。  1.真(zhen)空(kong)(kong)燒(shao)(shao)(shao)結(jie)(jie)爐可(ke)以減(jian)少(shao)(shao)氣氛(fen)里面(mian)的(de)(de)(de)(de)(de)一些(xie)(xie)有(you)害成(cheng)分,如(ru)氧(yang)、水(shui)以及氮(dan)等(deng)物質里面(mian)的(de)(de)(de)(de)(de)雜質,對于一些(xie)(xie)物料的(de)(de)(de)(de)(de)污(wu)染,可(ke)以避免出現滲碳(tan)、氧(yang)化、脫碳(tan)、滲氮(dan)以及還(huan)原等(deng)等(deng)反應。,對促進燒(shao)(shao)(shao)結(jie)(jie)后期的(de)(de)(de)(de)(de)收(shou)縮作用明顯。  2.真(zhen)空(kong)(kong)有(you)利于硅,鋁(lv),鎂,鈣等(deng)雜質或(huo)其氧(yang)化物的(de)(de)(de)(de)(de)排除,起到(dao)提純(chun)材料的(de)(de)(de)(de)(de)作用。  3.真(zhen)空(kong)(kong)可(ke)改善(shan)液(ye)相燒(shao)(shao)(shao)結(jie)(jie)的(de)(de)(de)(de)(de)潤濕性(xing)(xing),有(you)利于燒(shao)(shao)(shao)結(jie)(jie)過程(cheng)中的(de)(de)(de)(de)(de)收(shou)縮和(he)改善(shan)合金的(de)(de)(de)(de)(de)組織結(jie)(jie)構,提高(gao)了合金的(de)(de)(de)(de)(de)性(xing)(xing)能。  4.真(zhen)空(kong)(kong)是(shi)理想的(de)(de)(de)(de)(de)惰(duo)性(xing)(xing)氣氛(fen),當不宜用其他還(huan)原性(xing)(xing)或(huo)惰(duo)性(xing)(xing)氣體(ti)時,或(huo)者對容易(yi)出現脫碳(tan),滲碳(tan)的(de)(de)(de)(de)(de)材料,均可(ke)采用真(zhen)空(kong)(kong)燒(shao)(shao)(shao)結(jie)(jie)爐。  5.減(jian)少(shao)(shao)氣氛(fen)中的(de)(de)(de)(de)(de)有(you)害成(cheng)分(水(shui),氧(yang),氮(dan)等(deng))對產品(pin)的(de)(de)(de)(de)(de)玷污(wu)。例如(ru),電解(jie)氫中的(de)(de)(de)(de)(de)含(han)水(shui)量(liang)要求(qiu)降至lu點-40℃較為困難;而(er)真(zhen)空(kong)(kong)燒(shao)(shao)(shao)結(jie)(jie)時,真(zhen)空(kong)(kong)度只要在數百(bai)Pa就相當于含(han)水(shui)量(liang)為lu點-40℃  6.真(zhen)空(kong)(kong)燒(shao)(shao)(shao)結(jie)(jie)爐可(ke)以讓材料的(de)(de)(de)(de)(de)耐磨性(xing)(xing)和(he)強度更高(gao),還(huan)能夠降低產品(pin)的(de)(de)(de)(de)(de)生產成(cheng)本,從而(er)節約預算。
