I-Alumina ceramics ingasetshenziswa emishinini yokushisa okuphezulu kanye nemishini yokuguga okuphezulu embonini yamandla okushisa

Embonini yamandla okushisa, imishini ivame ukonakala ngenxa yendawo eshisa kakhulu kanye nezimo zokuguga okuphezulu, okuthinta ukukhiqizwa kokuphepha kohlelo lonke. Ukuze kuxazululwe le nkinga, kuyadingeka ukuthola izinto ezingamelana namazinga okushisa aphezulu futhi zimelane nokuguguleka. Izinto zobumba ze-Alumina zifaneleka kakhulu.

I-Alumina ceramic uhlobo lwe-alumina (Al2O3) njengezinto zokusetshenziswa ezenziwe ngezinto ze-ceramic, ngemva kokucindezela okomile, bese kuba ngaphezu kwama-degrees angu-1,700 okushisa okuphezulu. I-Alumina ceramics inezici zokuqhuba kahle, amandla omshini, ukumelana nokushisa okuphezulu kanye nokumelana nokugqwala. Ilinganiswa yi-Shanghai Institute of Silicate ye-Chinese Academy of Sciences, ubulukhuni bayo be-Rockwell buyi-HRA80-90, ubulukhuni bulandela idayimane kuphela, budlula kakhulu ukumelana nokugqwala kwensimbi engagqwali kanye nensimbi engagqwali. Ukumelana nokugqwala kuphindwe izikhathi ezingu-266 kunensimbi ye-manganese kanye nezikhathi ezingu-171.5 kunensimbi ephezulu ye-chromium. Ngokusho kocwaningo lwethu lokulandelela amakhasimende iminyaka engaphezu kweyishumi, ngaphansi kwezimo ezifanayo zokusebenza, impilo yokusebenza kwemishini ingandiswa okungenani izikhathi eziyishumi.

I-Alumina ceramics ingasetshenziswa ezingxenyeni zemishini eshisa kakhulu negugile embonini yamandla okushisa, njengeziphepheni, ama-pump rotor, amagobolondo, amapayipi, izihlalo, amasongo okuvala, njll. Lezi zingxenye zidinga ukumelana nokushisa okuphezulu, umfutho ophezulu kanye nemidiya egqwalisayo, ngakho-ke zidinga ukusebenzisa izinto ezinhle zokumelana nokugugile ukuze zikhiqize.

Embonini yamandla okushisa, umshini wokugaya amalahle uyimishini eyinhloko, kanye nokusetshenziswa kwawoizitsha zobumba ezingagugiingathuthukisa ngempumelelo impilo yesevisi yesigayo samalahle, bese iqinisekisa ukusebenza kohlelo lonke lwebhoyila. Lokhu akugcini nje ngokunciphisa isikhathi sokungasebenzi kahle kwemishini, kuqinisekise ukusebenza okuzinzile kohlelo lwebhoyila, kodwa futhi kunciphise nezindleko zokugcinwa kwemishini, okuhambisana nokuphishekela izinzuzo zomnotho embonini yamandla okushisa.

Kufanele kuqashelwe ukuthi ekusetshenzisweni okungokoqobo, imininingwane, okuqukethwe, ukucubungula kanye nokusetshenziswa kwezinto zobumba ezingagugi kudingeka kukhethwe ngokwezimo zokusebenza zangempela ukuqinisekisa ukusebenza okuhle kakhulu nemiphumela.
