Green silicon carbide ufa: chida chobisika chothandizira kupukuta bwino
Cha m'ma 2 koloko m'mawa, a Lao Zhou ochokera ku gulu loyang'anira mafoni am'manja adaponya chivundikiro chagalasi chomwe chinali chitangotuluka kumene patebulo loyang'anira, ndipo phokosolo linali lomveka ngati kuyatsa zozimitsa moto. "Taonani! Ndi gulu lakhumi! Manda alalanje ndi chifunga. Oyang'anira Apple afika mawa. Kodi izi zitha kuperekedwa?!" Magazi omwe anali m'maso mwake anali ofiira kuposa kuwala kwachitsulo pamakina. Li, yemwe anali chete pakona, anakankhira pang'onopang'ono chidebe cha ufa wobiriwira wobiriwira, "Yesani 'wamisala wobiriwira' uyu, ndikosangalatsa kwambiri kugaya mafupa olimba." Patatha masiku atatu, gulu loyamba la zinthu zoyenerera lidatumizidwa usiku wonse. Lao Zhou adasisita chidebe chaufa wobiriwirandipo anadandaula kuti: “Kamnyamata kopsa mtima kameneka kakhozadi kupulumutsa miyoyo!” M'bwalo lankhondo lakupukuta, lomwe ndi mpikisano wotsutsana ndi nthawi,green silicon carbide powder (SiC)ndi mankhwala amphamvu komanso ogwira mtima omwe amachitira makamaka mitundu yonse ya "osatha kugaya" ndi "osatha kupukuta".
Green silicon carbide powder, yotchedwa "green carbon" kapena "GC"Si mchenga wamba, koma munthu wolimba "woyengedwa" mu ng'anjo yamagetsi yamagetsi ya madigiri oposa 2000 ndi zipangizo monga mchenga wa quartz ndi petroleum coke.white corundum Chodabwitsa kwambiri ndi "zovala zake zobiriwira" - makristalo oyera kwambiri a silicon carbide, okhala ndi mbali zakuthwa ndi ngodya, komanso kupsa mtima kofulumira komanso kowopsa.green silicon carbidendi "kaputeni wogwetsa" atanyamula mace yaying'ono, okhazikika pakukuta mafupa olimba, ndipo mphamvu zake ndizodabwitsa.
Phindu lake lagona mu mzimu “wofulumira, wolondola, ndi wankhanza”:
1. Kuluma "mafupa olimba": kukhazikika pamitundu yonse ya kusamvera
Magalasi a foni yam'manja (Corning Gorilla), kalilole wowonera wa safiro, kachitsulo kakang'ono ka crystal silicon, gawo lapansi la ceramic… "Mapulojekiti amaso" amakampani amakono ndi ovuta komanso osalimba kuposa ena. Ma abrasives wamba sangagwire ntchito kapena kuthyola m'mphepete ngati agwiritsidwa ntchito mwamphamvu. Mphepete zakuthwa za silicon carbide ufa wobiriwira (monga ma chisel osawerengeka ang'onoang'ono pamlingo wa microscopic), kuphatikiza ndi kuuma kwake kwakukulu, amalola "kudula" pamwamba pa zinthu zolimba komanso zowonongeka mwamphamvu komanso mosadukiza. Imatha kusenda mwachangu zinthuzo, m'malo "mozilima" ngati zomatira kuti ziwononge kwambiri. Kupukuta chivundikiro cha foni yam'manja? Imatha kuphwanyitsa mwachangu "mapiri" pagalasi popanda kuphatikizira "zigwa" pafupi ndi iyo, kuwirikiza kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kawiri kanambembembedzaze? Ayi!
2. Kudula "mpeni wofulumira": nthawi ndi ndalama
Pamzere wopangira magalasi amtundu wa TFT-LCD, sekondi iliyonse yakupera m'mphepete ndi kupukuta kwa gawo lalikulu lagalasi lalikulu kumakhudzana ndi kupanga. "Liwiro" la ufa wobiriwira wa silicon carbide umalembedwa mu majini ake. Zigawo zake sizongolimba komanso zakuthwa, komanso modabwitsa kudzinola - tinthu tating'onoting'ono timadziphwanya tokha mopanikizika, ndikuwulula zakuthwa zatsopano kuti tipitirize kumenyana! Mosiyana ndi ma abrasives ena ofewa, amakhala "osalala" pamene akupera, ndipo mphamvu zawo zimatsika. Kuthekera kwa "kudzikonzanso" kumeneku kumapangitsa kukhala ngati nsomba m'madzi m'magawo ovuta komanso opukutira, ndipo kuchuluka kwake kochotsa zinthu pa nthawi ya unit (MRR) kuli patsogolo kwambiri kuposa opikisana nawo. Pambuyo pa fakitale ya photovoltaic silicon wafer yasintha kukhala wobiriwira wa silicon carbide slurry ndi kukula kwake kwa tinthu tating'onoting'ono, mphamvu ya kuchotsa m'mphepete mwa silicon yakula ndi 35%, ndipo mphamvu yopanga tsiku ndi tsiku ya mzere umodzi inafinyidwa ndi mazana a zidutswa - mu nyengo yofulumira kukhazikitsa, izi ndi ndalama zenizeni!
3. "Zabwino" pazovuta: kusanja bwino pakati pa kuchita bwino ndi kulondola
Musaganize kuti “amisala obiriwiraMwatsatanetsatane zenera la safiro kupukuta, kusankha yoyenera tinthu kukula (monga W7, W5 kapena ngakhale bwino pambuyo grading bwino) ndi chilinganizo cha wobiriwira pakachitsulo carbide micropowder amasonyeza "wosakhwima pansi roughness". Ikhoza efficiently kuchotsa zokopa zakuya ndi sub-surface zowonongeka zigawo zomwe zasiyidwa ndi zotsalira za diamondi zotsalira (zosanjikiza zotsalira za diamondi) zomwe zimasiyidwa ndi maziko okhazikika a diamondi Kwa kupukuta kwenikweni kotsatira (monga kugwiritsa ntchito silika sol) ndikofunika kwambiri popanda kuchotsa "kuvulala koopsa", sitepe yabwino yopukutira idzakulitsidwa kwambiri, ndipo zokolola zidzakhala zovuta kutsimikizira izi Iwo, “ntchito yabwino” ya kumata zojambula zagolidi pambuyo pake idzakhala yachabe.
4. Kusewera ndi "madzi akupera": kukhazikika ndi njira yokhalitsa
Green silicon carbide micropowder imakhala ndi mankhwala osasunthika (inert) ndipo sizovuta kuchitapo kanthu ndi madzi omwe amagwiritsidwa ntchito nthawi zambiri opangidwa ndi madzi kapena opaka mafuta. Kodi izi zikutanthauza chiyani? The slurry ali ndi kukhazikika bwino ndipo si kophweka kuwonongeka, kukhazikika kapena agglomerate! Pamzere wopukutira wokhala ndi digiri yapamwamba yodzipangira okha, kukhazikika kwa slurry ndiko njira yamoyo. Ganizilani izi, ngati chonyezimira nthawi zina chimakhala chokhuthala ndipo nthawi zina chopyapyala, ndipo tinthu tating'onoting'ono tating'onoting'ono kuti titseke payipi, kodi zokolola ndi kukonza zida zitha kukhala zoyipa bwanji? “Green Carbon"Slurry yokonzedwayo imatha kuyenda mozungulira kapena motalikirapo, ndikuchepetsa kwambiri kuchuluka kwa kuzimitsidwa kuti musinthe magawo ndi mapaipi oyeretsa." Lao Wu, woyang'anira zopangira fakitale yonyamula zida za ceramic, adati mokhudzidwa: "Popeza kuti silicon carbide slurry yokhazikika idasinthidwa, ndimatha kukhala pansi ndikumamwa tiyi usiku. Poyamba zinali ngati kuzimitsa moto!”
Munthawi ino yofunafuna kufewa komanso kuchita bwino,green silicon carbide micropowderwagwiritsa ntchito "zachiwawa kupsya mtima" mphamvu zake zolimba kusema yekha kothandiza ndi odalirika dzina pambuyo zosawerengeka yosalala kalilole-ngati pamwamba-si udindo wodekha, koma oyenerera "chida chinsinsi" kupititsa patsogolo kupukuta bwino.
