Chitoliro chachitsulo cholimba cha Alumina Ceramic chosatha kuvala: Katundu, Kupanga, ndi Kugwiritsa Ntchito

Chitoliro chachitsulo chokongoletsedwa ndi ceramic cha Aluminandi payipi yopangidwa ndi alumina ceramic yolimba kwambiri yopangidwa pogwiritsa ntchito alumina ceramic yoyera kwambiri ku khoma lamkati la chitoliro chachitsulo. Chigawo cha ceramic nthawi zambiri chimakhala ndi alumina yosachepera 95% (Al₂O₃), yokhala ndi kuuma kwa Rockwell kopitilira HRA85 ndi kuuma kwa Mohs kofanana ndi giredi 9, yachiwiri pambuyo pa diamondi. Kapangidwe kameneka kamaphatikiza kukana kwakukulu kwa alumina ceramic ndi mphamvu ndi kulimba kwa chitsulo, zomwe zimapangitsa kuti ikhale yoyenera pamavuto akulu. Mapangidwe a mapaipi amatsatira miyezo yaukadaulo ndipo amalola kusintha kutalika, m'mimba mwake, ndi njira zolumikizira.

Njira zazikulu zopangira ndi njira yolumikizira zomatira ndi njira yolumikizira. Njira yolumikizira imagwiritsa ntchito guluu wamphamvu kwambiri, wosatentha kuti amange matailosi a alumina ceramic omwe adapangidwa kale pakhoma lachitsulo chamkati, oyenera kutentha kwapakati mpaka kotsika (nthawi zambiri ≤150°C). Njira yolumikizira imagwiritsa ntchito njira zapadera zolumikizira matailosi a ceramic obowoka mwachindunji kukhoma lachitsulo chamkati, ndikupanga kulumikizana kwachitsulo pakati pa ceramic ndi chitoliro chapansi, chomwe chimalola kukana kutentha kwambiri (nthawi zambiri ≤350°C) komanso kukhudza kwamphamvu. Njira zonsezi zimatsimikizira kuti chitoliro cha ceramic chosalala, chopanda ming'alu chokhala ndi cholumikizira chodalirika ku chitoliro chapansi.

Ubwino waukulu wa payipi iyi uli mu kukana kwake kuvala bwino komanso nthawi yayitali yogwirira ntchito. Mu mikhalidwe yofanana yogwirira ntchito, kukana kwake kuvala kuli kopitilira nthawi 20 kuposa mapaipi wamba achitsulo cha kaboni, zomwe zimachepetsa kwambiri kuchuluka kwa ndalama zosinthira ndi kukonza. Kuphatikiza apo, imapereka kukana kwabwino kwa dzimbiri komanso malo osalala amkati, zomwe zimachepetsa kusonkhana kwa zinthu ndi kukana mayendedwe. Imagwiritsidwa ntchito kwambiri m'mafakitale monga kupanga magetsi, zitsulo, migodi, ndi kukonza mankhwala ponyamula ufa, kusamalira ming'alu, ndi makina otumizira mpweya, zomwe zimathandiza kuthetsa kutayika kwakukulu kwa mapaipi.
