Mullite lightweight insulation njerwa
Mafotokozedwe Akatundu
Njerwa zopepuka za mullite zimakhala ndi porosity yayikulu, yomwe imatha kupulumutsa kutentha kwambiri ndipo imachepetsa mtengo wamafuta.Pakalipano kulemera kwa kuwala kumatanthauza kuchepa kwa mphamvu yosungirako kutentha, choncho nthawi yochepa imafunika pamene ng'anjo yatenthedwa kapena itakhazikika.Kuthamanga kwapang'onopang'ono ndikotheka.
Itha kugwiritsidwa ntchito pa kutentha kuyambira 900 mpaka 1600 ℃.
Amagwiritsidwa ntchito kwambiri ngati ng'anjo yowotchera kutentha kwambiri (zosakwana 1700 ℃) zoumba zoumba, petrochemical, zitsulo ndi makina.
Zomwe Zimachitika
Low matenthedwe madutsidwe, otsika kutentha mphamvu, otsika zonyansa okhutira
Mphamvu yayikulu, kukana kwamphamvu kwamafuta, kukana kukokoloka
Mlingo wolondola
Kugwiritsa Ntchito
Mng'anjo ya ceramics ndi ng'anjo yowotchera: njerwa zokhazikika, njerwa zopumira, njerwa zophatikizira,
Makampani opanga zitsulo: ng'anjo yotentha yotentha;mkati mwa ng'anjo zamoto
Makampani opanga magetsi: zopangira magetsi ndi zida zabedi zothira madzi
Makampani a Electrolytic Aluminium: ng'anjo yamkati yamkati
Makhalidwe mankhwala
