Basa rekuchinja kweupfu hwealumina muindasitiri yeabrasive
Avo vakamboshanda mumaworkshop anokwesha vanoziva kuti zvinorwadza kubata nezvinhu zvakaoma - zvinopisa kubva pavhiri rekukuya, kukwenya panzvimbo yebasa, uye kudzikira kwehuwandu hwegoho. Chiso chemukuru chakasviba kupfuura pasi pehari. Kusvika pahupfu chena hweupfu hwealuminaZvayakapinda munhandare yehondo, zvakadhonzera indasitiri yechisimba munguva itsva. Nhasi, ngatitaurei kuti sei chinhu ichi chave "muponesi anokuya" weindasitiri yemazuva ano!
1. Ane tarenda: "murwi ane mativi matanhatu" muindasitiri yekurwisa nehasha
Upfu hweAlumina hunozvarwa kuti huve munhu akasimba anodya ndiro iyi yemupunga. Zvinhu zvitatu zvakasimba zvinopwanya shiri dzayo zvakananga:
Kuomarara kwakakwira: Kuomarara kweMohs kunotangira pa9.0, kuri kwechipiri kune dhaimani. Fekitori yezvishandiso muGuangdong yakayerwa: Pakucheka simbi inomhanya zvakanyanya, hupenyu hwemavhiri ekukuya ealumina hwakapetwa katatu kupfuura hwemabrasives akajairwa. Tenzi wekare Huang akati nefodya mumuromo make: “Ndaimbochinja vhiri rekukuya katatu pakucheka simbi ye alloy, asi ikozvino ndava kukwanisa kuzviita zvese ndisingafeme!”
Kuchena kunoshamisa: 99.6% α-Al₂O₃, tsvina yesimbi inodzikiswa kusvika pasi pe0.01%. Shanghai Semiconductor Factory yakarasikirwa: kushandisa mabrasives ane iron kupukuta mawafers, pamusoro payo paitaridzika sepockmarks mushure memwedzi mitatu; kushandisa alumina powder kurapa, haichinje ruvara kunyangwe mumabhati ane acid.
Kugadzikana kwekupisa kwakafanana nembwa yekare: nzvimbo yekunyunguduka 2050℃, thermal expansion coefficient yakaderera se4.8×10⁻⁶/℃. Fekitori yerocket nozzle muQingdao inoishandisa kukuya ma alloys anodziya zvakanyanya, uye kushanduka kwehukuru pasi pe1500℃ kushoma kupfuura dhayamita yebvudzi ka6.
Chinoshamisa ndechekuti inogona kuchinja chimiro chayo ka72 - kubva pa micron-level flat particles kusvika pa nano-level spherical powder, inogona kunge yakatenderera kana kuti yakati sandara sezvaunoda, uye yakagadzirirwa kurapa marudzi ese ekusateerera!
2. Chiitiko chechimurenga: "Kushanda kwechikamu chekuputika kwenyukireya" munhandare nhatu huru dzehondo
Musangano weSemiconductor: Unyanzvi hwekusona hweNano-level
Kupukuta simbi yesilicon wafer: Flat alumina micropowder inotsvedza pamusoro pesilicon wafer se skating, uye mwero wekukwenya unoderera ne70% nekukwenya kunotsvedza panzvimbo pekukwenya kwechinyakare. Nyanzvi yeSMIC yakati: "Basa iri rakanyanya kuoma kupfuura kusona!"
Chip yesilicon carbide: Nano-alumina polishing liquid inoboorera muchikamu chemachip, uye kushanda zvakanaka kwekupisa kunovandudzwa nemhedzisiro yequantum tunnel, uye mwero wegoho unokwira kusvika ku99.98%. Mainjiniya wepurojekiti akarova mufananidzo we electron microscope ndokuzvikudza achiti: "Kunyatsojeka uku kwakanyanya zvekuti kunyangwe umhutu hwakamira pairi hunofanira kupatsanura!"
Substrate yesafire: Submicron alumina inopolisha substrate ye LED kuita Ra<0.3nm, iyo inotsvedzerera kupfuura girazi. Mukuru weDongguan Optoelectronics Factory akati nemufaro: “Iye zvino tava kugadzira ma iPhone lenses, uye vaongorori veApple havagone kuwana mhosva nawo!”
Musangano wezvemotokari: inodhura zvakanyanya online
Ndege: nyanzvi dzinonetsa zvakanyanya
Kugadziriswa kwesimbi ye turbine blade mortise uye tenon:Alumina kukuya vhiriInoshanda pa nickel-based alloy, uye inogona kutsungirira maawa zana isina kurasikirwa nehupfu nekumhanya kwe2200 rpm. Mutyairi wekuyedza Lao Li akatarisa pachiratidziro chekutarisa ndokudanidzira achiti: "Nekuramba kupera uku, kunyange Musk anofanira kupfuudza fodya!"
Kupolisha madziro emukati me rocket nozzle: Upfu hwe alumina hwakaputirwa ne nano hunoderedza kuomarara kusvika paRa0.01μm, uye kushanda zvakanaka kwemafuta kunovandudzwa ne8%. Mainjiniya mukuru akati nemaziso matsvuku: "Chinhu ichi chimwe chete chinogona kuchengetedza matani matatu emafuta gore rega rega!"
3. Kurwisa kugadzirwa kwemumba: kubva pa "mutsipa wakanamatira" kusvika pa "kurwa nemaoko"
Mabrasive emumba ealumina aimbove "nyaya inosuwisa" - kusasimba kwekupfeka zvakanaka, mabheti asina kugadzikana, kuungana kwehupfu hwenano senge soup yemapundu, uye musika wepamusoro-soro waidzorwa nemakambani ekuAmerica neJapan13. Asi kuwanda kwenzvimbo dze semiconductor kwakamanikidza Jedi kurwisa:
Kurwiswa kweKuchena: Fekitori iri muLuoyang yakagadzira arc furnace intelligent control tembiricha, uye chiyero chekuchinja kwechikamu cheα chasvika 99.95%, uye kuchena kwacho kwakaenzana neShowa Denko yekuJapan.
Metaphysics yehukuru hwezvikamu: Makambani eZhejiang anoshandisa maAI turbine classifiers kudzora kugoverwa kwehukuru hwezvikamu mukati me ±0.1μm. Vatengi vekuKorea vakagumbuka pavakatarisa zvinhu: "Data iri rakarurama kupfuura detector!"
Kuzvarwazve kwemarara: Shandong base inopwanya uye inonatsazve mararamavhiri ekukuya, uye chiyero chekusanganiswa kwemvura chaderedzwa kusvika pa30%, uye mutengo wacho waderedzwa ne40%. Mutungamiriri weworkshop, Lao Zhou, akaseka ndokutuka achiti: “Marara aimboraswa asina kurongeka iye zvino ava kukosha kupfuura zvinhu zvitsva!”
4. Nzvimbo yehondo yeramangwana: mafambiro makuru matatu akagadzikana
Kudzora mazinga eNano: Rabhoritari yeHefei yauya netekinoroji nhema - tekinoroji yekuisa atomic layer kuisa "zvombo" paupfu hudiki uye kugadzirisa dambudziko rekubatana. Muongorori akasimudza muenzaniso ndokuzvikudza achiti: "Zvino kupukuta chip kwave kunyorova pane waxing!"
Chimurenga Chekurima: Chigadzirwa cheChongqing chinoshandisa sisitimu yekudzoreredza marara kuti chideredze kuburitswa kwematani mazana matatu emarara ane njodzi gore rega rega. Vanhu vekuEnvironmental Protection Bureau vakauya kuzoshanya ndokupa chigunwe chepamusoro vachiti: “Muchabvisa chigadzirwa chekuchenesa marara!”
Zvishandiso zvekuchenjera zvekukuya: Fekitori muZhengzhou yakaisa sensor yekumanikidza pavhiri rekukuya kuti igadzirise maparamita ekukuya panguva chaiyo. Xiao Liu, nyanzvi yemagetsi akazvarwa kuma1990, akanyora pakhibhodi ndokuzvikudza achiti: "Iye zvino kugadzirisa maparamita kuri nyore pane kutamba mitambo, uye mwero wekubudirira wasvika 99.8%!"
