Vanhu pavanonzwa izwi rekuti White Fused Alumina Micropowder, vazhinji vasiri muindasitiri yeabrasive vanogona kuriona serisingazivikanwe. Asi iyi upfu hwakatsetseka hunobatanidzwa muzvinhu zvakawanda zvehupenyu hwezuva nezuva—kubva pamafoni nemagirazi emaziso kusvika kuzvinhu zvemotokari nezvikamu zvemuchadenga. Sechinhu chinogadzirwa chakachena kwazvo, chine kuomarara kwakanyanya, upfu hwealumina hwakasanganiswa hunokosha nekuda kwemaitiro ahwo chaiwo ekugadzira uye kushandiswa kwakasiyana-siyana kwemaindasitiri.
Kubva paZvinhu Zvisina Kugadzirwa Kuenda kuMicropowder: Maitiro Akaoma Ekugadzira
Vazhinji vanofunga kuti upfu hudiki hunongogadzirwa nekupwanya tsanga huru chena dzakasanganiswa dzealumina, asi chokwadi chiripo chakaoma zvikuru.
1. Kusarudzwa Kwezvinhu Zvisina Kugadzirwa uye Kurapwa Kwepamberi
Upfu hwepamusoro hwe alumina chena hwakasanganiswa hunotanga nehupfu hwepamusoro hwe alumina hweindasitiri, hune kuchena kweAl₂O₃ kunodarika 99.5%. Zvinhu zvisina kuchena zvinogona kukanganisa kuomarara, kuchena, uye kugadzikana kwemakemikari. Upfu husati hwanyungudutswa, hunoongororwa uye hunoiswa muzvikamu zvemhepo kuti hubvise zvidimbu zvakakora uye huve nechokwadi chekuti zvidimbu zvakafanana kuti zvinyungudutswe zviri nani.
2. Kunyungudutsa uye Kugadzira Furnace yeMagetsi
Upfu hwealumina hwakagadziriswa kare hunozonyungudutswa muchoto chemagetsi chezvikamu zvitatu patembiricha ye2050–2150°C kwemaawa 4–6. Patembiricha iyi yakanyanya, alumina inonyunguduka zvizere kuita semvura, nepo tsvina ichiparadzana yodzikama nekuda kwekusiyana kwehuwandu.
Kudzora tembiricha kwakakosha panguva ino. Maelectrode anoiswa mukati medziva rakanyungudutswa kuti ave nechokwadi chekuti rinodziya zvakaenzana. Munguva yekutonhodza, kutonhora nekukurumidza kunoiswa pakupisa kwakanyanya, kuchiteverwa nekutonhora zvishoma nezvishoma pakupisa kwakaderera, zvichibvumira makristaro eα-Al₂O₃ akagadzikana kuumbwa. Kana atonhodzwa, chinhu chacho chinosimba kuita mapundu machena ealumina akabatana ane kuomarara kwakanaka uye kusimba.
3. Kupwanya, Kukuya, uye Kuronga Magadzirirwo Akarurama
Mabhuroko ealumina akasanganiswa anotanga apwanywa nemajaw crushers, ozochekwa zvakanaka nemaroller mills, uye pakupedzisira anogadzirwa kuita micron-scale powder achishandisa jet mills.
Kuti pave nekugoverwa kwakakwana kwehukuru hwezvikamu, kupatsanurwa kwepamusoro kwe hydraulic overflow uye masisitimu ekupatsanurwa kwemhepo anoshandiswa kupatsanura magiredhi akasiyana akadai seW5, W10, uye W20, nezvimwe zvigadzirwa zvichisvika pamazinga e submicron.
Mushure mekupatsanurwa, upfu hunogezwa neacid, huchigezwa nemvura, huchiomeswa, uye huchiparadzaniswa nemagnetic kubvisa tsvina yesimbi yasara, sodium, nezvimwe. Kuongorora kwekupedzisira kwehunhu kunosanganisira kuongororwa nemicroscope uye kuongorora saizi yezvidimbu usati warongedza.
Mashandisirwo Akakosha eWhite Fused Alumina Micropowder
Nekuda kwekuoma kwayo kukuru, kuchena kwayo kwakanyanya, uye kugadzikana kwayo kwemakemikari, upfu hwe alumina hwakasanganiswa huchena hunoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana.
Kukuya uye Kupukuta Nemazvo
Iyi ndeimwe yemabasa akakosha. Zvigadzirwa zvakaita sema optical lenses, LCD panels, uye semiconductor wafers zvinoda nzvimbo dzakanyatsotsvedzerera uye dzakanyatsorongeka.
Nekuomarara kweMohs kwe9—kwechipiri kubva kudhaimani—upfu hwealumina hwakasanganiswa huchena hune zvidimbu zvakapinza, zvakafanana zvinopenya zvakanaka pasina kukwenya pamusoro.
Inowanzoshandiswa kune:
- Skrini dzefoni dzeSapphire
- Magirazi egirazi
- Mapazi einjini dzemotokari
- Mabheyaringi akanyatsojeka
- Zvishandiso zvekurapa
Mishonga yakawanda yekupukuta uye slurry dzinoshandisawo upfu hwealumina micropowder hwakasanganiswa sechinhu chakakosha.
Kugadzira Zvishandiso Zvekutsamwisa Zvepamusoro-soro
Upfu hwe alumina hwakasanganiswa hunoshandiswa mukugadzira:
- Mavhiri ekukuya akabatanidzwa neResin
- Mavhiri ekukuya eCeramic
- Madhisiki ekucheka akatetepa zvikuru
- Mabhandi ejecha emhando yepamusoro uye anokwesha
Zvishandiso izvi zvinopa kupinza kwakanyanya, kupisa kushoma, uye hupenyu hurefu hwebasa, zvichiita kuti zvive zvakanaka pakukuya simbi isingasvibi, alloys dzakaoma, ceramics, uye pamusoro pehuni.
Zvinhu Zvinodzora Simba uye Zvekuzadza Maindasitiri
Nepo kunyunguduka kuri pamusoro pe2200°C uye kuchidzivirira kupisa, asidhi, uye alkali zvakanyanya, upfu hwealumina hwakasanganiswa imhando yepamusoro yezvinhu zvakagadzirwa zvemhando yepamusoro zvinoramba kusimba.
Inoshandiswa zvakanyanya mu:
- Matanda esimbi echoto
- Magirazi echitofu
- Mapfekero asingapfeki
- Zvinhu zvekusimbisa zveCeramic
- Zvinhu zvemagetsi zvekuputira zvekudzivirira kupisa uye kupisa
Remangwana reWhite Fused Alumina Micropowder
Kunyangwe ichiratidzika kunge upfu hwejena hwakajairika, upfu hwe alumina hwakasanganiswa hunobva mukugadzirwa kwakaoma uye kwakanyatsogadzirwa. Kubva pakusarudza zvinhu zvakabikwa kusvika pakurongedza kwekupedzisira, nhanho imwe neimwe inoda kudzorwa kwakanyatsojeka kuti ive nechokwadi chekuchena kwakanyanya uye kushanda kwakafanana.
Sezvo maindasitiri akadai sekugadzira zvinhu nemazvo, zvemagetsi, zvemagetsi, uye zvemichina yemagetsi zvichiramba zvichikura, kudiwa kwezvinhu zvemhando yepamusoro zvinogumbura kuchawedzera chete. Mune ramangwana, upfu huchena hwakasanganiswa nealumina huchaita basa rakakura mukushandiswa kwemaindasitiri epamusoro uye akagadziriswa.
Se "nyanzvi yekupukuta isingaoneki," upfu hwe alumina hwakasanganiswa hunoramba huchiumba nyika yemazuva ano—nzvimbo imwe chete yakatsetseka panguva imwe chete.
