Nkag mus rau hauv lub ntiaj teb thev naus laus zis ntawm ntsuab silicon carbide micropowder
Ntawm chav kuaj lub rooj ntawm lub Hoobkas hauv Zibo, Shandong, tus kws tshaj lij Lao Li tab tom khaws ib txhais tes ntawm cov hmoov ntsuab ntsuab nrog tweezers. "Qhov no yog sib npaug rau peb cov khoom siv tuaj txawv teb chaws hauv peb lub rooj cob qhia." Nws squinted thiab luag. Cov emerald xim no yog ntsuab silicon carbide micropowder hu ua "cov hniav kev lag luam". Los ntawm kev txiav cov iav photovoltaic mus rau kev sib tsoo ntawm cov nti substrates, cov khoom siv yees siv no nrog qhov loj me me dua li ib puas feem pua ntawm cov plaub hau yog sau nws cov lus dab neeg ntawm kev sib ntaus sib tua ntawm kev tshawb fawb thiab thev naus laus zis.
1. Cov txheej txheem thev naus laus zis dub hauv cov xuab zeb
Taug kev mus rau hauv lub rhiav ntau lawm ntawmntsuab silicon carbide micropowder, dab tsi hits koj tsis yog lub imagined hmoov av, tab sis ib tug ntsuab waterfall nrog ib tug hlau luster. Cov hmoov no nrog qhov nruab nrab me me ntawm tsuas yog 3 microns (sib npaug rau PM2.5 hais) muaj qhov tawv ntawm 9.5 ntawm Mohs nplai, thib ob tsuas yog pob zeb diamond. Yawg Wang, tus thawj coj ua haujlwm ntawm lub tuam txhab hauv Luoyang, Henan, muaj cov txuj ci tshwj xeeb: rub ib txhais tes ntawm micropowder thiab nphoo rau ntawm daim ntawv A4, thiab koj tuaj yeem pom cov qauv siv lead ua hexagonal nrog lub iav loj. "Tsuas yog cov crystals uas muaj qhov ua tiav ntawm ntau dua 98% tuaj yeem hu ua cov khoom lag luam zoo. Qhov no yog qhov nruj dua li kev zoo nkauj pageant." Nws hais tias thaum qhia cov duab microscopic ntawm daim ntawv tshaj tawm kev soj ntsuam zoo.
Tab sis kom tig pob zeb mus rau hauv cov thev naus laus zis thev naus laus zis, vaj txiaj ntsim ntuj ib leeg tsis txaus. Lub "kev taw qhia crushing thev naus laus zis" uas lub chaw soj nstuam hauv Jiangsu Xeev tau tawg dhau xyoo tas los tau nce kev ua haujlwm ntawm micro-hmoov txiav los ntawm 40%. Lawv tswj tau lub zog electromagnetic teb ntawm lub crusher kom yuam cov siv lead ua tawg raws ib lub dav hlau siv lead ua. Ib yam li "tua nyuj hla lub roob" hauv martial arts novels, qhov zoo li kev ua phem ntawm kev sib tsoo tiag tiag zais kev tswj hwm qib molecular. Tom qab siv thev naus laus zis no, qhov txiaj ntsig ntawm photovoltaic iav txiav tau nce ncaj qha los ntawm 82% mus rau 96%.
2. Tsis pom kev hloov pauv ntawm qhov chaw tsim khoom
Ntawm lub hauv paus tsim khoom hauv Xingtai, Hebei, tsib-zaj dab neeg arc rauv tau tawg tawm cov nplaim taws. Lub sijhawm qhov cub kub kub pom 2300 ℃, tus kws tshaj lij Xiao Chen txiav txim siab nias lub khawm pub. "Lub sijhawm no, sprinkling quartz xuab zeb zoo li tswj cov cua sov thaum ua noj." Nws taw tes rau qhov dhia spectrum nkhaus ntawm qhov kev tshuaj ntsuam xyuas thiab piav qhia. Niaj hnub no cov kev tswj hwm ntse tuaj yeem txheeb xyuas cov ntsiab lus ntawm 17 lub ntsiab lus hauv lub qhov cub hauv lub sijhawm tiag tiag thiab tuaj yeem kho qhov sib piv carbon-silicon. Xyoo tas los no, qhov system no tau tso cai rau lawv cov khoom lag luam zoo tshaj plaws los ntawm 90% cov cim, thiab cov khib nyiab tau ncaj qha txo los ntawm ob feem peb.
Nyob rau hauv lub rhiav muab qhab nia, lub turbine airflow sorting tshuab nrog ib txoj kab uas hla ntawm yim meters yog ua "kub panning nyob rau hauv cov xuab zeb hiav txwv". "Peb-theem plaub-dimensional sorting method" tsim los ntawm lub tuam txhab Fujian faib cov micropowder rau 12 qib los ntawm kev kho cov cua khiav ceev, kub, av noo, thiab nqi. Cov khoom zoo tshaj plaws 8000 mesh yog muag ntawm ntau tshaj 200 yuan ib gram, hu ua "Hermes hauv hmoov". Tus thawj coj ntawm lub rooj cob qhia Lao Zhang tso dag nrog tus qauv uas nyuam qhuav tawm hauv kab: "Yog tias qhov no tau nchuav, nws yuav mob ntau dua li cov nyiaj nchuav."
3. Kev sib ntaus sib tua yav tom ntej ntawm ntsuab ntse tsim
Saib rov qab ntawm kev sib tshuam ntawm kev siv thev naus laus zis thiab kev lag luam, zaj dab neeg ntawm ntsuab silicon carbide micropowder yog zoo li keeb kwm evolutionary ntawm lub ntiaj teb microscopic. Los ntawm cov xuab zeb thiab pob zeb mus rau cov ntaub ntawv txiav, los ntawm cov chaw tsim khoom mus rau cov hnub qub thiab dej hiav txwv, qhov kov ntawm ntsuab yog nkag mus rau hauv capillaries ntawm kev lag luam niaj hnub no. Raws li tus thawj coj tshawb fawb thiab kev tsim kho ntawm BOE tau hais tias: "Qee lub sijhawm nws tsis yog cov loj heev uas hloov lub ntiaj teb, tab sis cov khoom me me uas koj tsis pom." Raws li ntau lub tuam txhab pib delve rau hauv lub ntiaj teb microscopic no, tej zaum cov noob ntawm kev hloov kho thev naus laus zis tom ntej no tau muab zais rau hauv cov hmoov ci ntsuab ua ntej peb ob lub qhov muag.
