Chubu Choteteza Alumina Ceramic
Zambiri Zamalonda
Machubu a AluminaAmagawidwa makamaka m'machubu a corundum, machubu a ceramic ndi machubu a aluminiyamu okwera, omwe amasiyana mu kapangidwe kake, mawonekedwe ake, ndi ntchito zake.
Chubu cha Corundum:Zinthu zopangira za chubu cha corundum ndi alumina, ndipo gawo lalikulu ndi α-alumina (Al₂O₃). Kulimba kwa chubu cha corundum ndi kwakukulu, kulimba kwa Rockwell ndi HRA80-90, ndipo kukana kutopa ndikwabwino kwambiri, komwe kuli kofanana ndi kuwirikiza nthawi 266 kuposa chitsulo cha manganese ndi kuwirikiza nthawi 171.5 kuposa chitsulo cha chromium chochuluka. Kuphatikiza apo, chubu cha corundum chili ndi mawonekedwe a kukana kutsika, kukhuthala kwakukulu komanso kukhazikika kwabwino kwa mankhwala. Nthawi zambiri chimagwiritsidwa ntchito m'zigawo zosatha kutopa, mabearing a ceramic, zisindikizo, ndi zina zotero. Kuphatikiza apo, machubu a corundum amagwiritsidwanso ntchito popangira mawotchi ndi makina olondola.
Chubu cha ceramic:Kapangidwe ka chubu cha ceramic kangakhale alumina woyeretsedwa kwambiri (monga 99 porcelain) kapena alumina wamba (monga 95 porcelain, 90 porcelain, ndi zina zotero). Ma ceramic a alumina woyeretsedwa kwambiri (monga 99 porcelain) ali ndi Al₂O₃ yoposa 99.9%, ndi kutentha kotentha mpaka 1650-1990℃. Ali ndi kuwala kowala bwino komanso kukana dzimbiri la alkali metal. Machubu a ceramic a alumina woyeretsedwa kwambiri nthawi zambiri amagwiritsidwa ntchito mu nyali za sodium ndi ma substrates ophatikizidwa a circuit ndi zipangizo zotetezera kutentha kwambiri mumakampani amagetsi chifukwa cha kuwala kwawo koyeretsedwa bwino komanso kukana dzimbiri. Machubu a ceramic a alumina wamba amagwiritsidwa ntchito pa ma crucible otentha kwambiri, machubu a ng'anjo yotsutsa komanso zipangizo zapadera zosavala.
Chubu cha aluminiyamu chapamwamba:Chigawo chachikulu cha machubu okhala ndi aluminiyamu yambiri ndi alumina, koma nthawi zambiri amakhala pakati pa 48%-82%. Machubu okhala ndi aluminiyamu yambiri amadziwika kuti ndi olimba kwambiri komanso opirira kutentha kwambiri. Amagwiritsidwa ntchito kwambiri m'magawo monga machubu oteteza thermocouple ndi machubu ophimba machubu a tubular. Amatha kuteteza bwino zigawo zamkati ku kuwonongeka kwa kutentha kwambiri ndikuwonjezera nthawi yawo yogwira ntchito.
