Uyini umehluko phakathi kwezinga lokushisa eliphezulu calcined α alumina powder kanye ne-corundum emhlophe

I-high-temperature calcined α alumina micropowder kanye ne-corundum emhlophe zombili zicutshungulwa kusukela ku-alumina powder yezinga lezimboni njengezinto zokusetshenziswa, kodwa ubuchwepheshe bokucubungula buhlukile, futhi umkhiqizo ophelile nawo unomehluko othile. Izinga lokushisa eliphezulu calcined α alumina powder icutshungulwa kuhhavini womhubhe noma kuhhavini ojikelezayo ku-1300-1400°C. Inokumelana nokushisa okuphezulu nokumelana nokugqoka, ngakho-ke isetshenziswa kakhulu ezintweni eziphikisayo nezimboni ze-ceramic. I-corundum emhlophe yenziwa ngokuncibilika ekushiseni okuphezulu ngaphezu kwama-degree angu-2000 ku-arc kagesi bese ipholiswa. Iyachotshozwa futhi yakhiwe, ihlukaniswe ngozibuthe ukuze ikhiphe insimbi, futhi isefe ibe yizinhlayiyana ezinosayizi abahlukahlukene. Ngenxa yokuthi i-corundum emhlophe inamakristalu aminyene, ubulukhuni obuphezulu, namakhona abukhali, ifanele ukukhiqiza izitsha zobumba. , Ama-abrasives e-Die, ukupholishwa, ukuqhunyiswa kwesihlabathi, ukusakaza okunembayo, njll. Ingasetshenziswa futhi ukwenza izinto eziphikisayo zezinga eliphezulu. Kuyi-abrasive ebaluleke kakhulu.

I-alpha-alumina micropowder enezinga eliphezulu lokushisa eliphezulu ayinzima kakhulu ukuyicubungula, futhi izindleko zokucubungula nazo ziphansi, ngakho-ke isetshenziswa kakhulu ezimbonini eziphikisayo neze-ceramic. Yehlisa izindleko zokukhiqiza ngenkathi uhlangabezana nezidingo zamakhasimende.

Ngaphezu kwalokho, i-alumina powder ekhiqizwe kahle yezinga eliphezulu ingasetshenziswa kumamvilophu e-electronic vacuum, ama-spark plugs nezinye izinto zobumba zikagesi, izindandatho zokuvala, izinto zobumba ezingagqoki njengemishini yendwangu, izinsimbi ze-alumina, amashubhu e-porcelain nezinye izinga lokushisa eliphezulu. izinto zokwakha, i-high-frequency insulating ceramics, LCD substrates Glass njll.
