Kafukufuku pa Kugwiritsa Ntchito Zirconia Powder mu High-End Precision polishing
Ndikukula mwachangu kwa mafakitale apamwamba kwambiri monga zamagetsi ndi ukadaulo wazidziwitso, opanga ma optical, ma semiconductors, ndi zida zadothi zapamwamba, zofunikira zapamwamba zikuyikidwa pamtundu wa zinthu zakuthupi. Makamaka, pamakina olondola kwambiri azinthu zazikulu monga safiro, magalasi owoneka bwino, ndi mbale zolimba za disk, momwe zinthu zopukutira zimagwirira ntchito zimatsimikizira momwe makinawo amagwirira ntchito komanso mtundu womaliza wa pamwamba.Zirconia powder (ZrO₂), mkulu-ntchito zakuthupi zakuthupi, pang'onopang'ono akutulukira m'munda wa mkulu-mapeto mwatsatanetsatane kupukuta chifukwa cha kuuma kwambiri, kukhazikika matenthedwe, kuvala kukana, ndi katundu kupukuta, kukhala woimira m'badwo wotsatira wa zipangizo kupukuta pambuyo cerium okusayidi ndi aluminium okusayidi.
I. Katundu waZirconia Powder
Zirconia ndi ufa woyera wokhala ndi malo osungunuka kwambiri (pafupifupi 2700 ° C) ndi mitundu yosiyanasiyana ya kristalo, kuphatikizapo monoclinic, tetragonal, ndi cubic phases. Zirconia ufa wokhazikika kapena wokhazikika pang'ono ukhoza kupezedwa powonjezera kuchuluka kwa stabilizers (monga yttrium oxide ndi calcium oxide), zomwe zimalola kuti zisunge kukhazikika kwagawo komanso makina amakina ngakhale kutentha kwambiri.
Zirconia powderUbwino waukulu wa 's akuwonekera makamaka muzinthu izi:
Kulimba kwambiri komanso luso lopukuta bwino: Ndi kuuma kwa Mohs kwa 8.5 kapena kupitilira apo, ndikoyenera kupukuta komaliza kwa zinthu zosiyanasiyana zolimba kwambiri.
Kukhazikika kwamphamvu kwamankhwala: Imakhalabe yokhazikika m'malo okhala acidic kapena amchere pang'ono ndipo sivuta kukhudzidwa ndi kusintha kwamankhwala.
Dispersibility bwino: Kusinthidwa nano- kapena submicron-sizezirconia powderskuwonetsa kuyimitsidwa kwabwino kwambiri komanso kuyenda bwino, kumathandizira kupukuta kofanana.
Kutsika kwamafuta otentha komanso kuwonongeka kocheperako: Kutentha komwe kumapangidwa panthawi yopukutira kumakhala kochepa, kumachepetsa kupsinjika kwamafuta komanso chiwopsezo cha ma microcracks pamtunda wokonzedwa.
II. Momwe Mungagwiritsire Ntchito Zirconia Powder mu Precision polishing
1. Kupukuta kwa Sapphire Substrate
Makristalo a safiro, chifukwa cha kuuma kwawo kwakukulu komanso mawonekedwe abwino kwambiri a kuwala, amagwiritsidwa ntchito kwambiri mu tchipisi ta LED, magalasi owonera, ndi zida za optoelectronic. Zirconia ufa, ndi kuuma kwake kofanana ndi kuchepa kochepa, ndi chinthu choyenera cha mankhwala opangidwa ndi makina opukuta (CMP) a safiro. Poyerekeza ndi chikhalidwealuminiyamu okusayidi kupukuta ufaZirconia, zirconia, imathandizira kwambiri kutsetsereka kwapamwamba komanso kutsirizika kwa galasi ndikusunga mitengo yochotsa zinthu, kuchepetsa mikanda ndi ma microcracks.
2. Kupukuta kwagalasi
Pokonza zinthu zowoneka bwino monga ma lens olondola kwambiri, ma prisms, ndi nkhope zomata za ulusi, zida zopukutira ziyenera kukwaniritsa ukhondo wapamwamba kwambiri komanso zofunikira za fineness. Kugwiritsa ntchito kuyeretsa kwakukuluzirconium oxide ufandi kulamulira tinthu kukula kwa 0.3-0.8 μm monga chomaliza kupukuta wothandizila amakwaniritsa otsika kwambiri padziko roughness (Ra ≤ 1 nm), kukwaniritsa zokhwima "chopanda cholakwika" amafuna zipangizo kuwala.
3. Hard Drive Platter ndi Silicon Wafer Processing
Ndi kuchuluka kosalekeza kwa kachulukidwe kasungidwe ka data, zofunikira za hard drive platter surface flatness zikuchulukirachulukira.Zirconia powder, yogwiritsidwa ntchito popukuta bwino pazitsulo zolimba, imayendetsa bwino zowonongeka zowonongeka, kukonza bwino kulemba kwa disk ndi moyo wautumiki. Kuphatikiza apo, pakupukuta kopitilira muyeso kwa zowotcha za silicon, zirconium oxide imawonetsa kuyanjana kwapamwamba komanso kutayika kochepa, ndikupangitsa kuti ikhale njira yokulirapo kuposa ceria.
Ⅲ. Zotsatira za Kukula kwa Particle ndi Dispersion Control pa Zotsatira Zopukuta
Kupukuta kwa zirconium oxide ufa kumakhudzana kwambiri osati ndi kuuma kwake kwakuthupi ndi mawonekedwe a kristalo, komanso kumakhudzidwa kwambiri ndi kugawa kwake kwa tinthu ndi kubalalitsidwa.
Kukula kwa Tinthu ting'onoting'ono: Kukula kwakukulu kwa tinthu ting'onoting'ono kumatha kuyambitsa zokanda pamwamba, pomwe kung'ono kwambiri kumatha kuchepetsa mitengo yochotsa zinthu. Choncho, ma micropowders kapena nanopowders omwe ali ndi D50 osiyanasiyana a 0.2 mpaka 1.0 μm amagwiritsidwa ntchito kuti akwaniritse zofunikira zosiyanasiyana.
Kubalalitsidwa Magwiridwe: Good dispersibility kupewa tinthu agglomeration, amaonetsetsa kukhazikika kwa njira kupukuta, ndi bwino processing dzuwa. Mafuta ena apamwamba a zirconia, atasinthidwa pamwamba, amawonetsa kuyimitsidwa kwabwino mumadzi am'madzi kapena ofooka acidic, kumagwira ntchito mokhazikika kwa maola ambiri.
IV. Development Trends ndi future Outlook
Ndi kupita patsogolo kosalekeza kwaukadaulo wa nanofabrication,zirconia powdersakukonzedwa kuti akhale oyera kwambiri, kugawa tinthu kakang'ono, ndi kuwonjezereka kwa dispersibility. Madera otsatirawa akuyenera kuwunikiranso mtsogolo:
1. Kupanga Misa ndi Kukonzekera kwa Mtengo wa Nano-ScaleZirconia Powder
Kulimbana ndi mtengo wapamwamba ndi ndondomeko yovuta yokonzekera ufa woyeretsa kwambiri ndizofunikira kwambiri polimbikitsa kugwiritsa ntchito kwawo kwakukulu.
2. Kupanga Zinthu Zophatikiza Zopukuta
Kuphatikiza zirconia ndi zinthu monga aluminiyamu ndi silika kumapangitsa kuti mitengo yochotsamo komanso mphamvu zowongolera pamwamba.
3. Green ndi Environmental Friendly Polishing Fluid System
Konzani zofalitsa zosakhala ndi poizoni, zowola komanso zowonjezera kuti mulimbikitse chilengedwe.
V. Mapeto
Zirconium oxide ufa, yokhala ndi zinthu zabwino kwambiri zakuthupi, ikugwira ntchito yofunika kwambiri pakupukuta mwatsatanetsatane kwambiri. Ndi kupita patsogolo kosalekeza kwaukadaulo wopanga komanso kukwera kwamakampani, kugwiritsa ntchitozirconium oxide ufaidzafalikira kwambiri, ndipo ikuyembekezeka kukhala chithandizo chachikulu cham'badwo wotsatira wa zida zapamwamba zopukuta. Kwa makampani oyenerera, kuyenderana ndi kukweza kwazinthu ndikukulitsa ntchito zapamwamba pantchito yopukutira kudzakhala njira yofunika kwambiri yokwaniritsira kusiyanitsa kwazinthu ndi utsogoleri waukadaulo.
