Uma abantu bezwa igama elithi White Fused Alumina Micropowder, abaningi abangaphandle kwemboni yokuhudula bangase bakuthole kungajwayelekile. Kodwa-ke le mpuphu emhlophe ecolekile ihileleke buthule ezicini eziningi zokuphila kwansuku zonke—kusukela ezikrinini ze-smartphone namalensi ezibuko zamehlo kuya ezingxenyeni zezimoto kanye nezingxenye zezindiza. Njenge-abrasive yokwenziwa ehlanzekile kakhulu, eqinile kakhulu, i-alumina micropowder emhlophe ehudulayo iyaziswa ngenqubo yayo yokukhiqiza enembile kanye nobubanzi bezicelo zezimboni.
Kusukela Kuzinto Ezingavuthiwe Kuya Ku-Micropowder: Inqubo Yokukhiqiza Eqinile
Abaningi bacabanga ukuthi i-micropowder yenziwa ngokuchoboza izinhlamvu ezinkulu ezimhlophe ze-alumina ezihlanganisiwe, kodwa iqiniso liyinkimbinkimbi kakhulu.
1. Ukukhethwa Kwezinto Ezingavuthiwe Nokwelashwa Kwangaphambi Kokwelashwa
I-alumina micropowder emhlophe ehlanganisiwe esezingeni eliphezulu iqala nge-alumina powder yezimboni ye-premium, enobumsulwa be-Al₂O₃ obungaphezu kuka-99.5%. Izinto ezihlanzekile zingathinta ubulukhuni, ubumhlophe, kanye nokuqina kwamakhemikhali. Ngaphambi kokuncibilikisa, i-powder eluhlaza iyahlolwa futhi ihlukaniswe emoyeni ukuze kususwe izinhlayiya eziqinile futhi kuqinisekiswe usayizi wezinhlayiya ezifanayo ukuze kuncibilike kahle.
2. Ukuncibilika Nokubumbana Kwesithando Somlilo Se-Arc Sikagesi
Impuphu ye-alumina elungisiwe kusengaphambili incibilikiswa esithandweni sikagesi esinezigaba ezintathu emazingeni okushisa angu-2050–2150°C amahora angu-4–6. Kuleli zinga lokushisa elibi kakhulu, i-alumina incibilika ngokuphelele ibe uketshezi, kuyilapho ukungcola kuhlukana futhi kuhlala ngenxa yokwehluka kobuningi.
Ukulawulwa kwezinga lokushisa kubalulekile phakathi nalesi sigaba. Ama-electrode afakwa ngokujulile echibini elincibilikisiwe ukuqinisekisa ukushisa okufanayo. Ngesikhathi sokupholisa, ukupholisa okusheshayo kusetshenziswa emazingeni okushisa aphezulu, kulandelwe ukupholisa okuhamba kancane emazingeni okushisa aphansi, okuvumela ukwakheka kwamakristalu e-α-Al₂O₃ azinzile. Uma esepholile, izinto ziyaqina zibe yizigaxa ze-alumina ezimhlophe ezihlanganisiwe ezinobulukhuni obuhle kakhulu nokuqina.
3. Ukuchoboza, Ukugaya, kanye Nokuhlukaniswa Ngokucophelela
Amabhulokhi e-alumina ahlanganisiwe aqala ngokuchotshozwa yizicucu zemihlathi, bese kuncishiswa kahle yizicucu ze-roller, bese ekugcineni kucutshungulwa kube yimpuphu ye-micron kusetshenziswa izicucu ze-jet.
Ukuze kufezwe ukusatshalaliswa kosayizi wezinhlayiya okunembile, ukuhlukaniswa okuthuthukisiwe kokuchichima kwe-hydraulic kanye nezinhlelo zokuhlukaniswa kokugeleza komoya kusetshenziselwa ukuhlukanisa amamaki ahlukene njenge-W5, i-W10, kanye ne-W20, kanti eminye imikhiqizo ifinyelela amazinga angaphansi kwe-micron.
Ngemva kokuhlukaniswa, impuphu igezwa nge-asidi, igezwa ngamanzi, yomiswe, futhi ihlukaniswe nge-magnetic ukuze kususwe insimbi esele, i-sodium, nokunye ukungcola. Ukuhlolwa kokugcina kwekhwalithi kuhlanganisa ukuhlolwa nge-microscope kanye nokuhlaziywa kosayizi wezinhlayiya ngaphambi kokupakisha.
Ukusetshenziswa Okubalulekile kwe-White Fused Alumina Micropowder
Ngenxa yobulukhuni bayo obuphezulu, ubumsulwa bayo obuphezulu, kanye nokuqina kwamakhemikhali, i-white fused alumina micropowder isetshenziswa kabanzi ezimbonini eziningi.
Ukugaya Nokupholisha Okunembile
Lokhu kungenye yezindlela ezibaluleke kakhulu zokusebenzisa. Imikhiqizo efana namalensi optical, amaphaneli e-LCD, nama-wafer e-semiconductor adinga izindawo ezibushelelezi kakhulu nezinembile.
Njengoba ubulukhuni bukaMohs bungu-9—okwesibili ngemva kwedayimane—i-white fused alumina micropowder inikeza izinhlayiya ezibukhali nezifanayo ezipholisha kahle ngaphandle kokuklwebha ubuso.
Ngokuvamile isetshenziselwa:
- Izikrini ze-smartphone ze-Sapphire
- Amalensi ezibuko zamehlo
- Izinsika zenjini yezimoto
- Amabheringi aqondile
- Amadivayisi ezokwelapha
Ama-compound amaningi okupholisha kanye nama-slurry abrasive nawo asebenzisa i-white fused alumina micropowder njengesithako esiyinhloko.
Ukukhiqiza Amathuluzi Ahluphayo Asezingeni Eliphezulu
I-white fused alumina micropowder isetshenziswa ekukhiqizeni:
- Amasondo okugaya aboshwe nge-resin
- Amasondo okugaya e-Ceramic
- Amadiski okusika amancane kakhulu
- Amabhande e-sandpaper asezingeni eliphezulu kanye namabhande ahudulayo
Lawa mathuluzi anikeza ubukhali obuphezulu, ukukhiqizwa kokushisa okuphansi, kanye nokuphila isikhathi eside kwenkonzo, okwenza afaneleke kakhulu ekugayeni insimbi engagqwali, ama-alloy aqinile, izinto zobumba, kanye nezindawo zokhuni.
Izinto Zokucwenga Nezigcwalisi Zezimboni
Njengoba izinga lokuncibilika lingaphezu kuka-2200°C futhi limelana kahle nokushisa, i-asidi, kanye ne-alkali, i-alumina micropowder emhlophe ehlanganisiwe iyinto eluhlaza efanelekile yemikhiqizo ethuthukisiwe yokungaguquguquki.
Isetshenziswa kabanzi ku:
- Izembozo zesithando sensimbi
- Izindwangu zesithando seglasi
- Izembozo ezingagugi
- Izinto zokuqinisa ze-ceramic
- Izinto zokupakisha ze-elekthronikhi zokushisa nokushisa
Ikusasa Le-White Fused Alumina Micropowder
Nakuba kubonakala sengathi yimpuphu emhlophe nje evamile, i-alumina micropowder emhlophe ehlanganisiwe iwumphumela wenqubo yokukhiqiza eqinile neyinkimbinkimbi. Kusukela ekukhetheni izinto zokusetshenziswa kuya ekupakisheni kokugcina, isinyathelo ngasinye sidinga ukulawulwa okunembile ukuqinisekisa ubumsulwa obuphezulu nokusebenza okulinganayo.
Njengoba izimboni ezifana nokukhiqiza ngokunemba, izinto zikagesi, ama-optics, kanye nama-semiconductor ziqhubeka nokukhula, isidingo sezinto ezihudulayo ezisezingeni eliphezulu sizokhula kuphela. Esikhathini esizayo, i-alumina micropowder emhlophe ehlanganisiwe izodlala indima enkulu nakakhulu ekusetshenzisweni kwezimboni okuthuthukisiwe nokucwengisisiwe.
Njengo “uchwepheshe wokupholisha ongabonakali,” i-alumina micropowder emhlophe ehlanganisiwe iyaqhubeka nokubumba umhlaba wanamuhla—indawo eyodwa ebushelelezi ngesikhathi.
