Kukuya Kuputika Kupukuta Media 240#-12500# Upfu Hwechena Hwakabatanidzwa hweAlumina
Tsananguro yeWFA
Corundum chena ine upfu hwealumina yeindasitiri sezvinhu zvakabikwa, iri mu arc mushure mekunyunguduka kwekupisa kwakanyanya kwemadhigirii 2000 mushure mekutonhora, kukuya nekugadzira, kupatsanurwa kwemagineti kubvisa simbi, kuvharwa kuita granularity yakasiyana-siyana, magadzirirwo ayo akaomarara, kuomarara kwakanyanya, zvidimbu zvinoumba Angle yakapinza, yakakodzera kugadzirwa kweceramics, resin consolidation abrasive tools uye grinding, polishing, sandblasting, precision casting (investment casting special corundum), nezvimwewo. Inogona zvakare kushandiswa kugadzira zvinhu zvinoramba kushanda zvakanaka.

Kushandiswa kweWFA
1. Gadzira zviumbwa zveceramic zvinoonekera: marambi e sodium ane simba guru, hwindo reEP-ROM.
Αalpha-Al2O3 inogona kupiswa kuita ceramic inoonekera kuti ishandiswe serambi re sodium rine simba rakawanda; pamwe chete nerambi re fluorescent rakapfava muchikamu chekudzivirira che phosphor layer kuti ivandudze hupenyu hwerambi.
2. Sezvinhu zvekupukuta zvepamusoro-soro zve: girazi, simbi, zvinhu zve semiconductor, plastiki, tepi, bhandi rekukuya, nezvimwewo.
3. Sechinowedzerwa: pendi yekusimbisa, rabha, inodzivirira kupera simba kwepurasitiki.
Sechinhu chitsva chinosanganiswa, upfu hweAl2o3 hunogona kushandiswa sekusimbisa kupararira uye sekuwedzera, zvakaita sekuwedzera alumina nanoparticles murabha, kuramba kupfeka kunogona kuvandudzwa kakawanda.
4. Shandisa sechinosimudzira, chinotakura chinobatsira, uye sechinogadzirisa zvinhu.
Nekuda kwehunhu hwayo hwakakosha, upfu hweAl2o3 hunoshandiswa zvakanyanya sechinokonzeresa uye sechinotakura, muzvigadzirwa zveceramics nedzimwe nzvimbo.
5. Shandisa pakuputira
Alumina nanoparticles sezvinhu zvinovheneka uye pamusoro pechinhu chinodzivirira chinogona kutora chiedza che ultraviolet, uye mune mamwe mawavelength echiedza anogona kugadzirwa nehukuru hwechidimbu chewavelength yechiedza.
6.Kushandisa simba guru resimbi
Mukushandiswa kweceramic, ceramics dzakagadzirwa ne nano alumina powder dzine plasticity yesimbi yakafanana uye kusimba, huremu hwakareruka, kunyanya, hunowedzera simba zvakanyanya.
Nekuwedzera huwandu hushoma hwe nano-alumina mu ceramic matrix yemazuva ano inogona kuita kuti hunhu hwemakanika hwezvinhu zvakapetwa kaviri huwedzere kusimba kweceramics kuderedza tembiricha yayo yekupisa.
- Inoshandiswa pakukuya mahara, senge indasitiri yegirazi.
2. Inoshandiswa pakugadzira zvinhu zvinokweshana uye pasi rinodzivirira kupfekwa.
3. Yakakodzera resin kana ceramic bond abrasive, senge grinding wheel, kucheka grinding wheel, nezvimwewo.
4. Yakakodzera zvigadzirwa zvinoramba kusimba, zvinodzivirira kupera uye zvinoramba kusimba.
5. Inoshandiswa pakukwesha, zvakaita semagedhi, mabhuroko ekukwesha, kutenderedza maplate, nezvimwewo.
6. Inoshandiswa pakuputira zvishandiso zvinokwesha, zvakaita sejecha, jira reemery, bhandi rejecha, nezvimwewo.
7. Inoshandiswa pakugadzira chakuvhuvhu nemazvo.
