Ufa Wobiriwira wa Silicon Carbide: Chizindikiro Chatsopano cha Zipangizo Zogwira Ntchito Kwambiri komanso Zosunga Mphamvu
I. Kodi kwenikweni ndi chiyani? N’chifukwa chiyani imatchedwa “Hardcore”?
Choyamba, tiyeni timvetse zomweufa wobiriwira wa silicon carbide micropowderndi. Taganizirani ngati mtundu wa "diamondi yopangira." Ngakhale kuti ndi yolimba pang'ono poyerekeza ndi diamondi yeniyeni, mosakayikira ndi yolimba kwambiri. Imayengedwa mu uvuni wotentha kwambiri pa madigiri Celsius oposa 2,000 pogwiritsa ntchito mchenga wa quartz, petroleum coke, ndi zipangizo zina zopangira, zomwe zimapangitsa kuti ikhale yobiriwira kwambiri.
Chikhalidwe chake "cholimba" chimawonetsedwa makamaka m'mbali zitatu:
Kulimba Kwambiri ndi Mphepete Mwakuthwa: Kulimba kwake kwa Mohs kumafika pa 9.2, chachiwiri pambuyo pa diamondi. Izi zikutanthauza kuti podula ndi kupukuta, imagwira ntchito ngati dzino laling'ono, lakuthwa, "lopera" mosavuta kudzera muzinthu zolimba komanso zofooka monga ma wafers a silicon a photovoltaic, galasi la safiro, ndi ma crystals a piezoelectric.
Kulimba Kwambiri, Kukonda Kusweka M'malo Mopindika: Kulimba kokha sikokwanira; kumafunanso kulimba. Zipangizo zina zimakhala zofooka kwambiri ndipo zimasweka n’kukhala ufa wosalala zikakanikizidwa, zomwe zimapangitsa kuti zisagwire ntchito. Ufa wobiriwira wa silicon carbide umadzitamandira ndi kulimba kwambiri pamene umakhala wolimba kwambiri. Umasunga mawonekedwe ake pansi pa kupanikizika kwakukulu, ndipo umagwiritsa ntchito mphamvu pa ntchito popanda kusweka.
Yokhazikika komanso yogwira ntchito molimbika: Pa kutentha kwa chipinda, imakumana ndi ma acid kapena maziko aliwonse, zomwe zimapangitsa kuti ikhale chinthu chogwira ntchito molimbika. Izi zikutanthauza kuti panthawi yodula, imapewa kusintha kwa mankhwala kosafunikira ndi zinthu zomwe zikukonzedwa, ndikuwonetsetsa kuti zinthuzo ndi zoyera. Izi ndizofunikira kwambiri m'mafakitale a photovoltaic ndi semiconductor, komwe kuyera ndikofunikira kwambiri.
II. Kugwiritsa ntchito bwino mphamvu komanso kusunga mphamvu—si mawu opanda pake okha
Kufika pa mfundo: N’chifukwa chiyani imatchedwa “chiwerengero chatsopano”? Kodi kugwiritsa ntchito bwino mphamvu komanso kusunga mphamvu kumeneku kwawonetsedwa bwanji? Tiyeni tidule zinthu zochepa ndikuwonetsa zochitika zina zothandiza.
Chitsanzo 1: "Zodulira Zolondola" za Photovoltaic Silicon Wafers
Lao Zhang, ndiwe wodziwa bwino izi.Zinthu zopangidwa ndi siliconMasiku ano ndi okwera mtengo kwambiri. Kuduladula kocheperako kumabweretsa ma wafer ambiri, zomwe zimachepetsa ndalama. Komabe, ma wafer a silicon ocheperako amatha kusweka mosavuta, zomwe zimafuna miyezo yapamwamba yodulira ukadaulo ndi ma abrasives. Ufa wobiriwira wa silicon carbide, wokhala ndi mawonekedwe ofanana a tinthu tating'onoting'ono komanso m'mbali mwake zakuthwa, umapanga mphamvu zodulira zokhazikika komanso zofanana panthawi yodulira. Zotsatira zake:
Kudula bwino kwambiri: Ma wafer ambiri amatha kudulidwa nthawi yomweyo, kapena liwiro lodula lingawonjezeke.
Ubwino wapamwamba: Kuwonongeka kwa pamwamba pa ma wafer a silicon odulidwa ndi kochepa, ndipo TTV (kusiyana kwa makulidwe onse) ndi kochepa, zomwe zimapangitsa kuti phindu liwonjezeke mwachangu.
Kutaya zinthu zochepa: Kudula bwino kumabweretsa kutayika kochepa kwa kerf, kuchepetsa kutayika kwa zinthu zodula za silikoni. Pa ndalama zomwe nthawi zambiri zimaposa mayuan mazana ambiri, ndalama zomwe zimasungidwa zimakhala zambiri.
Chitsanzo chachiwiri: "Wothamanga wopirira" pakupanga safiro
Magalasi ambiri a kamera ya foni yanu ndi magalasi apamwamba owonera amapangidwa ndi safiro. Safira ndi wovuta kwambiri kuposa galasi ndipo ndi wovuta kwambiri kuwagwiritsa ntchito. Kugwiritsa ntchito zinthu wamba zopukutira kungathe kuichepetsa pakapita nthawi yochepa, zomwe zimachepetsa kwambiri magwiridwe antchito. Komabe, ufa wobiriwira wa silicon carbide micropowder, chifukwa cha kukana kwake kutopa, umasungabe kuwala kwa nthawi yayitali, ndikuwonjezera moyo wake wautumiki. Izi zikutanthauza:
Kusintha kwa zinthu mopupuluma kumachepa, nthawi yogwira ntchito imachepetsedwa, ndipo mphamvu yopangira zinthu imawonjezeka.
Ndalama zonse zogulira zinthu zimachepetsedwa. Ngakhale kuti mtengo pa tani imodzi ukhoza kukhala wokwera, kugwira ntchito bwino komanso kuchepetsa kugwiritsa ntchito zinthu zina kumachepetsa mtengo wonse. Izi ndi zoona “kusunga mphamvu.”
Chitsanzo Chachitatu: Kufalikira ku Dziko Lonse
Mphamvu zake zimapitirira izi. Kuziyika mu zipangizo zamakono zotetezera kutentha kumatha kukulitsa moyo wa ma uvuni ndikuwonjezera kutchinjiriza kutentha, ndikusunga mphamvu bwino m'mafakitale omwe amagwiritsa ntchito mphamvu zambiri. Mu zipangizo zophatikizika, monga chowonjezera mphamvu, zimapangitsa kuti zinthu zikhale zolimba komanso zolimba, zomwe zimapangitsa kuti zida zosungiramo zida zisamawonongeke komanso zikhale zolimba, zomwe zimapangitsa kuti zida zosungiramo zinthu zisamawonongeke - komanso njira yobisika yosungira mphamvu. Ngakhale mumakampani opanga ndege, ndizofunikira kwambiri pogaya molondola zinthu zina zapadera zadothi.
III. Njira Yotsogola: Yabwino Kwambiri, Yofanana Kwambiri, Yanzeru Kwambiri
Zachidziwikire, ufa wobiriwira wa silicon carbide si wangwiro. Kuti tipeze "chiwerengero chatsopanochi," opanga athu ayenera kugwira ntchito mwakhama m'magawo angapo:
Kukonza kosalekeza kwa kukula kwa tinthu tating'onoting'ono: Makampani otsika pansi pa nthaka akufuna kulondola kwambiri. Tikufunika kupanga ufa wochepa wokhala ndi kugawa kwakukulu kwa tinthu tating'onoting'ono komanso mawonekedwe okhazikika a tinthu tating'onoting'ono (isomorphism yabwino). Izi zili ngati gulu la asilikali omwe akuyenda limodzi ndikuyenda mbali imodzi kuti agwire bwino ntchito yankhondo. Kuchuluka kwa tinthu tating'onoting'ono ndi tating'onoting'ono (kotchedwa "coarse" ndi "fine") kuyenera kulamulidwa mosamala; apo ayi, kudula kudzapangitsa kuti ntchitoyo ikhwime komanso kuti ntchitoyo ichepe.
Luso losintha pamwamba: Kusintha pamwambatinthu tating'onoting'ono ta ufandi ntchito yaukadaulo kwambiri. Mwachitsanzo, kuonjezera kugwirizana kwawo ndi zinthu zodulira ndi zomangira utomoni kungathandize kwambiri kudula bwino komanso kugwira ntchito bwino kwa zinthuzo. Zili ngati kudzola mafuta lupanga—sikungonola m'mphepete mwake komanso kumawonjezera kulimba kwake.
Kupanga Zinthu Zobiriwira: Ngakhale kuti ndi chinthu chosunga mphamvu, kodi njira yake yopangira zinthu ingakhale yosunga mphamvu komanso yoteteza chilengedwe? Mwachitsanzo, kugwiritsa ntchito mphamvu m'zitofu zosungunulira, kusonkhanitsa fumbi panthawi yoponda ndi kuyeretsa, komanso kubwezeretsanso madzi—zonsezi zomwe zimafuna kusinthidwa kosalekeza ndi kubwerezabwereza mkati mwa makampani athu. Timayesetsa kupanga zinthu zobiriwira nthawi zonse.
Kwa ife omwe tili mumakampani opanga zinthu, nkhani ya ufa wobiriwira wa silicon carbide yangoyamba kumene. Kupangitsa kuti ikhale yokonzedwa bwino, yatsatanetsatane, komanso yanzeru ndiye gawo lathu lalikulu kwambiri pakuyendetsa ntchito yopanga zinthu zapamwamba ku China kuti igwire bwino ntchito komanso kuti isunge mphamvu.
