Njerwa zamoto zopepuka zopepuka zimagwiritsidwa ntchito kwambiri mu insulation system of kilns. Kugwiritsa ntchito njerwa zopepuka zotchinjiriza zamoto kwapeza zotsatira zina zopulumutsa mphamvu komanso zoteteza chilengedwe pantchito yotentha kwambiri.
Njerwa yamoto yonyezimira yopepuka ndi chinthu chotchinjiriza chokhala ndi kachulukidwe kakang'ono kwambiri, porosity yayikulu, komanso kutsika kwamafuta. Makhalidwe ake a otsika kachulukidwe ndi otsika matenthedwe madutsidwe kupanga izo Irreplaceable mu kilns mafakitale.
Kupanga ndondomeko yanjerwa yopepuka yoyaka moto
1. Yezerani zopangira molingana ndi chiŵerengero chofunikira, perani chinthu chilichonse kukhala ufa. Onjezani madzi ku mchenga wa silika kuti mupange slurry ndikuwotcha kutentha kwa 45-50 ℃;
2. Onjezerani zotsalira zotsalira ku slurry ndikugwedeza. Pambuyo kusakaniza kwathunthu, tsitsani slurry wosakanizidwa mu nkhungu ndikutenthetsa mpaka 65-70 ° C kuti mufufuze thovu. Kuchuluka kwa thovu kumaposa 40% ya ndalama zonse. Pambuyo pochita thovu, sungani pa 40 ° C kwa maola awiri.
3. Mukayimirira, lowetsani m'chipinda chotenthetsera kuti muwotche, ndikuthamanga kwa 1.2MPa, kutentha kwa 190 ℃, ndi nthawi yotentha ya maola 9;
4. High kutentha sintering, kutentha 800 ℃.
