Basa reshanduko realuminium poda muindasitiri yeabrasive
Avo vakashanda mumasangano abrasive vanoziva kuti kutemwa nemusoro kutarisana nepamusoro-kuoma zvinhu - mazhenje kubva pagumbo rekukuya, kukwenya panzvimbo yebasa, uye kudonha kwegoho. Chiso chasabhuku chasviba kudarika pasi pepoto. Kusvikira hupfu huchena hwealumina powderyakamhanyira munhandare yehondo, yakakwevera indasitiri yakashata kupinda munguva itsva. Nhasi, ngatitaurei kuti sei chinhu ichi chave "muponesi anokuya" weindasitiri yemazuva ano!
1. Talented: "hexagonal warrior" mune abrasive indasitiri
Alumina poda anozvarwa ari mukomana akaomarara anodya ndiro iyi yemupunga. Zvitatu zvakaoma-musimboti zvivakwa zvinopwanya vezera rayo:
Kuoma kwakakwirira: Kuoma kweMohs kunotanga pa9.0, yechipiri chete kune diamond. Fekitori yezvishandiso muGuangdong yakayerwa: Kana uchicheka simbi inomhanya-mhanya, hupenyu hwealumina inokuya mavhiri inopeta katatu pane yeakajairika mabrasives. Mukuru mukuru Huang akati nefodya mumuromo make: “Ndaiwanzochinja vhiri rokukuya katatu pakucheka simbi inosanganiswa nesimbi, asi iye zvino ndinogona kuzviita pasina kumbofema!”
Kuchena kunoshamisa: 99.6% α-Al₂O₃ yemukati, tsvina yesimbi inodzvanywa kusvika isingasviki 0.01%. Shanghai Semiconductor Factory yakatambura kurasikirwa: kushandisa iron-containing abrasives kupora wafers, nzvimbo yacho yakaita semapockmarks mushure memwedzi mitatu; kushandisa alumina poda kurapa, haichinji ruvara kunyangwe mumabhati ane acid.
Kugadzikana kwekupisa kwakafanana nembwa yakwegura: nzvimbo inonyunguduka 2050℃, coefficient yekuwedzera kwemafuta yakaderera se4.8×10⁻⁶/℃. Fekitori yeroketi nozzle muQingdao inoishandisa kukuya-tembiricha alloys, uye saizi yekuchinja pasi pe1500 ℃ nharaunda isingasviki ka6 padhayamita yebvudzi.
Chinotonyanya kushamisa ndechekuti inogona kushandura chimiro chayo ka72 - kubva pamicron-level flat particles kuenda ku nano-level spherical powder, inogona kunge yakaita denderedzwa kana kuti yakati sandara sezvaunoda, uye yakagadzirirwa kurapa marudzi ese ekusateerera!
2. Chiitiko cheChimurenga: “Kuputika-padanho rekuputika kwenyukireya” munzvimbo nhatu dzehondo huru
Semiconductor musangano: Nano-level embroidery hunyanzvi
Silicon wafer polishing: Flat alumina micropowder skims pamusoro peiyo silicon wafer seskating, uye mwero wekukwenya unodonha ne70% nekutsvedza kukuya pachinzvimbo chekuumburuka yechinyakare. Mudzidzisi weSMIC akati: “Basa iri harina kusimba kupfuura kusona!”
Silicon carbide chip: Nano-aluminium polishing liquid drills mukati me chip gap, uye kupisa kwekushisa kunovandudzwa ne quantum tunnel effect, uye chiyero chegoho chinokwira kusvika 99.98%. Injiniya wepurojekiti akabhabhadzira mufananidzo wemaikorosikopu erekitironi ndokudada achiti: “Kunyatsoita uku kwakakwira zvekuti kana umhutu humire pauri hunotozotsemuka!”
Sapphire substrate: Submicron alumina inopukuta iyo LED substrate kuRa <0.3nm, inotsvedzerera kupfuura girazi. Mukuru weDongguan Optoelectronics Factory akati nemufaro: "Iye zvino tave kugadzira ma iPhone lens, uye vaongorori veApple havasi kuwana mhosva kwavari!"
Automotive workshop: mutengo muurayi pamhepo
Aerospace: yakanyanyisa dambudziko nyanzvi
Turbine blade mortise uye tenon kugadzirisa:Alumina achikuya vhiriinoshanda pane nickel-based alloy, uye inogona kumira kwemaawa zana pasina kurasikirwa nehupfu nekumhanya kwe2200 rpm. Mutyairi webvunzo Lao Li akatarisa pachiratidziri chekutarisa uye akashevedzera kuti: "Nekusapfeka uku, kunyange Musk anofanira kudarika fodya!"
Rocket nozzle yemukati madziro polishing: Nano-yakavharidzirwa alumina poda inoderedza kushata kusvika kuRa0.01μm, uye kushanda kwemafuta kunovandudzwa ne8%. Injiniya mukuru akati nemaziso matsvuku: “Chinhu chimwe chete ichi chinogona kuchengetedza matani matatu emafuta gore negore!
3. Counterattack yekugadzirwa kwemumba: kubva "kunamira mutsipa" kuenda ku "ruoko mutsimba"
Domestic alumina abrasives yaimbove "nyaya inosuruvarisa" - kushomeka kwekusagadzikana, mabheji asina kugadzikana, nano powder agglomeration senge pimple soup, uye musika wepamusoro wakatorwa nemakambani eAmerica neJapan13. Asi mafungu e semiconductor localization akamanikidza Jedi counterattack:
Kurwiswa kwakachena: Fekitari muLuoyang yakagadzira arc choto chakangwara chekudzora tembiricha, uye α chikamu chekushandura chasvika 99.95%, uye kuchena kwakaenzana neJapan Showa Denko.
Particle size metaphysics: Makambani eZhejiang anoshandisa AI turbine classifiers kudzora kugoverwa kwesaizi mukati me ± 0.1μm. Vatengi vekuKorea vakasiya shaya vachiongorora zvinhu: "Iyi data ndeyechokwadi kupfuura detector!"
Kuberekwazve kwemarara: Shandong base inopwanya uye inonatsazve tsvinakugaya mavhiri, uye admixture reshiyo yakaderedzwa kusvika 30%, uye mutengo unoderedzwa ne40%. Mutungamiriri wewekishopu, Lao Zhou, akaseka ndokutsiura, kuti: “marara aichimboraswa arasika zvino anokosha zvikuru kupfuura zvinhu zvitsva!”
4.Nhengo yehondo yeramangwana: maitiro makuru matatu akagadzikana
Nano-level control: Hefei laboratory yauya neblack tekinoroji - atomic layer deposition tekinoroji yekuisa "zvombo" pahupfu hudiki uye kugadzirisa dambudziko reagglomeration. Muongorori akasimudza sampuli ndokuzvirova dundundu achiti: “Iye zvino kuporiswa kwechipisi kuri kutsvedzerera pane kunakisa!”
Green Revolution: Chirimwa cheChongqing chinoshandisa tsvina yeasidhi yekudzoreredza sisitimu kudzikisa kubuda kwematani mazana matatu emarara ane ngozi gore rega rega. Vanhu veEnvironmental Protection Bureau vakauya kuzoshanya ndokupa chigunwe kuti: “Muri kuzorasa pombi yetsvina!”
Smart kugaya maturusi: Fekitori muZhengzhou yakaisa yekumanikidza sensor paguyo rekukuya kugadzirisa maparamendi ekukuya munguva chaiyo. Xiao Liu, nyanzvi yakazvarwa kuma1990s, akataipa pakibhodhi ndokudada achiti: "Iye zvino kugadzirisa ma parameter kuri nyore pane kutamba mitambo, uye chiyero chegoho chasvika 99.8%!"
