Nhanganyaya, kushandiswa uye kugadzirwa kwe white corundum
Alumina Chena Yakasanganiswa (WFA)ipurasitiki yakagadzirwa nehupfu hwealumina hweindasitiri sechinhu chikuru, inotonhodzwa uye inonatswa mushure mekunyunguduka kwearc pakupisa kwakanyanya. Chikamu chayo chikuru ialuminium oxide (Al₂O₃), ine kuchena kweinopfuura 99%. Ichena, yakaoma, yakakora, uye ine simba rakanaka rekudzivirira kupisa kwakanyanya, inodzivirira ngura uye inochengetedza kupisa. Ndiyo imwe yeabrasives dzepamusoro dzinoshandiswa zvakanyanya.
1. Nhanganyaya yeChigadzirwa
Corundum chena rudzi rwecorundum yekugadzira. Kana ichienzaniswa necorundum yebrown, ine huwandu hushoma hwekusvibiswa, kuomarara kwakanyanya, ruvara ruchena, haina silica yakasununguka, uye haina njodzi kumuviri wemunhu. Yakakodzera zvakanyanya pazviitiko zvekugadzira zvine zvinodiwa zvakanyanya zvekuchena, ruvara uye kugona kukuya. Corundum chena ine kuomarara kweMohs kusvika ku9.0, yechipiri chete kune diamond nesilicon carbide. Ine hunhu hwakanaka hwekuzvirodza, haisi nyore kunamira pamusoro pebasa panguva yekukuya, uye inokurumidza kupisa. Yakakodzera nzira dzekugadzirisa dzakaoma uye dzakanyorova.
2. Mashandisirwo Makuru
Nekuda kwehunhu hwayo hwakasiyana hwemuviri uye hwemakemikari, white corundum inoshandiswa zvakanyanya muminda yakawanda yepamusoro-soro, kusanganisira asi kwete kungogumira kune zvinotevera:
Maturusi ekukuya nekushandisa pakukuya
Inoshandiswa kugadzira mavhiri ekukuya eceramic, mavhiri ekukuya e resin, jira re emery, sandpaper, scouring pads, grinding pastes, nezvimwewo. Chinhu chakanakira kukuya chesimbi ine kabhoni yakawanda, simbi ye alloy, simbi isina ngura, girazi, ceramics nezvimwe zvinhu.
Kuputira jecha nekupukuta
Yakakodzera kuchenesa pamusoro pesimbi, kubvisa ngura, kusimbisa pamusoro uye kugadzirisa matte. Nekuda kwekuoma kwayo kwakanyanya uye kusakuvadza uye kusakuvadza, inowanzoshandiswa pakuputira jecha nekupukuta mapundu akanyatsogadzirwa uye zvigadzirwa zvesimbi isingatsvedzi.
Zvinhu zvinodzivirira mhepo
Inogona kushandiswa sehupfu hwakasanganiswa kana hwakatsetseka hwezvidhinha zvemhando yepamusoro zvinoramba kushanda, zvinhu zvinogadziriswa, uye zvinhu zvinogadziriswa. Inoshandiswa zvakanyanya munzvimbo dzinopisa zvakanyanya dzakadai sesimbi, simbi inonyungudutsa simbi isina ferrous, magirazi emoto, nezvimwewo.
Indasitiri yemagetsi/yemaziso
Inoshandiswa kugadzira zvicherwa zveceramic zvine purity yakakwira, kukuya kwegirazi re optical, kupukuta kwe LED sapphire substrate, kuchenesa nekukuya kwe semiconductor silicon wafer, nezvimwewo, uye upfu hwe corundum white hwakachena hwakanyanya hunodiwa.
Kuzadza kunoshanda
Inoshandiswa murabha, mapurasitiki, machira ekuputira, magirazi eceramic nedzimwe nzvimbo dzeindasitiri kuti ivandudze kuramba kupfeka, kugadzikana kwekupisa uye mashandiro ekudzivirira kupisa kwezvinhu.
3. Maitiro ekugadzira
Maitiro ekugadzira white corundum akaomarara uye ane sainzi, kunyanya kusanganisira matanho akakosha anotevera:
Kugadzirira zvinhu zvisina kugadzirwa
Sarudza upfu hwe alumina hweindasitiri hwakachena kwazvo (Al₂O₃≥99%), ongorora uye edza zvinhu zvakagadzirwa nemakemikari kuti uve nechokwadi chekuti kusvibiswa kwacho kwakaderera zvakanyanya uye saizi yezvikamu zvakaenzana.
Kunyunguduka kweArc
Isa upfu hwealumina muchoto chearc chine zvikamu zvitatu wochinyungudutsa patembiricha yepamusoro inosvika 2000℃. Munguva yekunyungudutsa, maelectrode anodziiswa kuti anyungudise alumina zvachose uye abvise tsvina kuti agadzire corundum melt yakachena.
Kutonhodza kristalllization
Kana mvura yanyunguduka yatonhodzwa, inogomera kuita makristaro machena ecorundum. Kutonhodza zvishoma nezvishoma kunobatsira kukura kwezviyo uye kushanda zvakanaka, inova chinhu chikuru chinoita kuti corundum tsvuku ive yakanaka.
Kupwanya uye kupatsanurwa kwemagineti
Makristasi ecorundum anotonhodzwa anopwanywa uye anopwanywa zvakanaka nemidziyo yemakanika, uye tsvina yakaita sesimbi inobviswa nekupatsanurwa kwakasimba kwemagineti kuitira kuti chigadzirwa chapera chive chakachena.
Kupwanya uye kuongorora
Shandisai mabhora, ma air flow mill nezvimwe zvishandiso kupwanya corundum chena kusvika pahukuru hwe particle hunodiwa, uye shandisai michina yekuongorora yakanyatsogadzirwa kuti muwane saizi ye particle zvichienderana nezvinodiwa pasi rose (senge FEPA, JIS) kuti muwane jecha kana micro powder ine specifications dzakasiyana.
Kuchenesa zvakanaka (zvichienderana nechinangwa)
Kune mamwe mashandisirwo epamusoro-soro, akadai seupfu hwe corundum chena hwe electronic grade ne optical grade, kupatsanurwa kwemhepo, kutorwa kwe pickling uye kuchenesa kwe ultrasonic kunoitwa kuti kuwedzere kuvandudza kuchena uye kutonga kwehukuru hwezvikamu.
Kuongorora kwemhando yepamusoro uye kurongedza
Chigadzirwa chapera chinofanira kudzorwa nenzira dzakasiyana siyana dzakadai sekuongorora makemikari (Al₂O₃, Fe₂O₃, Na₂O, nezvimwewo), kuona saizi yezvidimbu, kuona kuchena, nezvimwewo, uye mushure mekupasa bvunzo, chinoiswa mupakeji zvinoenderana nezvinodiwa nevatengi, kazhinji mumabhegi e25kg kana mabhegi etani.
Sechinhu cheindasitiri chine mashandiro akanaka kwazvo, corundum chena ine basa risingatsiviwi mumaindasitiri mazhinji. Haisi chete mumiriri akakosha wezvigadzirwa zvepamusoro-soro, asiwo chinhu chakakosha muminda yepamusoro-soro senge machining akarurama, ceramics inoshanda, uye zvinhu zvemagetsi. Nekuvandudzwa kuri kuramba kuchiita tekinoroji yeindasitiri, zvinodiwa zvemhando yepamusoro yecorundum chena zviri kuramba zvichivandudzika, izvo zvinokurudzirawo vagadziri kuti varambe vachivandudza maitiro avo, vawedzere kushanda kwechigadzirwa, uye vakure nenzira yekuchena kwakanyanya, saizi yezvidimbu zvakapfava, uye mhando yakagadzikana.
