Calcium ndi silicon: awiriwa amtsogolo aukadaulo? 

Mumamva zambiri za silicon, mwachiwonekere. Koma kugwirizana ndi calcium? Ndipamene kukambirana kumakhala kosangalatsa, ndipo moona mtima, kusamvetsetsana pang'ono kunja kwa mabwalo ena. Sikungopanganso zitsulo zolimba.

Pambuyo pa Ng'anjo: Maganizo Olakwika

Anthu ambiri, ngakhale m'magawo oyandikana nawo aukadaulo, amawona silicon ya calcium ngati chinthu chochuluka chazitsulo - kuyimitsa kwathunthu. Imapita mu ladle kuti deoxidation, mwina nodularizing chitsulo kuponyedwa, ndipo ndilo dziko lake. Lingaliro loti aloyi wonyozekayi ikhoza kukhala yothandiza kwambiri pakupanga zinthu zapamwamba, kusungirako mphamvu, kapenanso zamagetsi zamtundu wamtsogolo zikuwoneka ngati kutambasula. Ndilo kulakwitsa koyamba: kupeputsa udindo wa chiyero chakuthupi ndikuchitanso koyenera. Mukamagwira nawo ntchito, mumazindikira kuti magwiridwe antchitowo samangowonjezera 'kuwonjezera calcium,' koma m'magawo olondola, kuwongolera kuphatikiza, ndi uinjiniya wa tinthu. Gulu lokhala ndi morphology yosiyana pang'ono kapena ma trace elements lingathe kusokoneza njira yoponyera yolondola kwambiri. Ndaziwona zikuchitika.

Izi zimatsogolera ku mfundo yachiwiri: kufufuza. Osati zonse calcium silicon amapangidwa mofanana. Kudalirika kwa ma chain chain, kusasinthika kuchokera ku maere kupita ku maere, ndikofunikira kwambiri kuposa kale. Makampani omwe amawatenga ngati chinthu amawotchedwa. Mwachitsanzo, wopanga ma silicon opangidwa ndi solar omwe tidagwira naye ntchito anali ndi vuto losalekeza ndi mbeu zonyansa m'mitsuko yawo. Vutoli lidayambikanso pakusinthika kwamitundu mchere wa calcium amagwiritsidwa ntchito poyambira sitepe. Kusintha kwa ogulitsa omwe ali ndi njira zowongolera, monga Malingaliro a kampani Inner Mongolia Xinxin Silicon Industry Co.,Ltd, yomwe imagwira ntchito imodzi mwamizere yayikulu yophatikizika yopanga, idapanga kusiyana kowonekera. Kukhazikitsa kwawo ndi makonzedwe odzipatulira a molybdenum, titaniyamu, ndi zosintha zina zikuwonetsa kuyang'ana kwapadera, komwe ndikofunikira.

The nuance ali mu mafomu kompositi. Sikuti ndi CaSinso. Ndi silicon barium calcium yopititsa patsogolo inoculation, kapena waya wokhala ndi mawonekedwe enaake osungunuka. Apa ndipamene gawo la 'tech' limayamba kukwawa. Simukungogula alloy; mukugula phukusi lantchito. Kuthekera kwa kampani kupereka izi - kuchokera ku ferrosilicon wamba kupita ku ma noduzer apadera ndi waya wopindika - kumawonetsa kuya komwe kumadyedwa ndi mapulogalamu apamwamba kwambiri.

Vuto la Chiyankhulo: Kumene Chiphunzitso Chimakumana ndi Kusungunuka

M'mawu othandiza, lonjezo la calcium silicon nthawi zambiri amapunthwa pa mawonekedwe-kwenikweni. Kodi mumayiyambitsa bwanji kuti ikhale yotentha kwambiri? Jekeseni wa waya wa cored anali wosintha masewera, koma adabweretsa mutu wake womwe. Kupeza liwiro la chakudya, makulidwe a waya, ndi kuya kwa kumiza molakwika kumatanthauza kusabereka bwino, kupsa mtima, ndi kuwonongeka kwamtengo wapatali. Ndimakumbukira mlandu womwe unachitikira pamalo opangira zitsulo pomwe tinkakonza zopangira chitsulo chatsopano, chocheperako. Waya wokhazikika adayambitsa zachiwawa kwambiri. Tidayenera kugwirira ntchito limodzi ndi wopanga aloyi kuti tiwongolere kapangidwe kake ndi kachulukidwe kuti tipeze kutulutsa kosalala, koyendetsedwa bwino. Zinatenga kubwereza katatu.

Ndiye pali vuto la kuyeza. Mukuwonjezera izi kuti zikhudze mawonekedwe ang'onoang'ono pamlingo wocheperako, koma mayankho anthawi yeniyeni ndi olakwika. Nthawi zambiri mumadalira zowonera za post-cast komanso kuyezetsa kwamakina, zomwe zikutanthauza kuti kuwongolera kukuchedwa. Ichi ndi kusiyana kwakukulu. M'tsogolomu sikuti mumangokhala ndi ma alloys abwino, koma muzophatikizana bwino - masensa omwe amatha kuzindikira mphamvu ya kusinthidwa munthawi yeniyeni, mwina kudzera mu kusanthula kwamafuta kapena ma ultrasonics apamwamba. Sitinafikebe.

Ichi ndichifukwa chake machitidwe otsimikizira zamtundu wa opanga sangakambirane. Ngati kuyesa kwawo kwamkati sikuli kolimba, kusinthasintha kwanu kutsika kumakwera kwambiri. Gulu lathunthu la zida zoyesera zolondola, monga tafotokozera mu mbiri ya Xinxin Silicon Viwanda, sizogulitsa; ndiye maziko a aliyense amene akufuna kupitilira kupanga zinthu. Ndizomwe zimalola kupangidwa kwa zinthu zomwe zimapangidwira ngati ma deoxidizer kapena ma desulfurizer.

Kupatula Mwamsanga pa Silicon Metal Payokha

Simungathe kuyankhula za awiriwa popanda kuvomereza mbali ya silicon. Kukankhira kwapamwamba-kuyera chitsulo cha silicon kwa polysilicon ndi zamagetsi zimapanga malingaliro osangalatsa. Njira zoyeretsera zitsulo zoyeretsera silicon nthawi zambiri zimakhala ... Chifukwa chake kufunikira kwaukadaulo pakuyendetsa silicon kopitilira muyeso kumawongoleranso njira zogwiritsira ntchito ma aloyi a calcium. Ndi kusintha kwa mafakitale a symbiotic.

Zotsatira za Ntchito Yotsatira: Mphamvu ndi Zowonjezera

Kodi izi zimapitilira pati zitsulo zachikhalidwe? Magawo awiri akuwonetsa zonyezimira. Choyamba, ma anode a batri. Silikoni ndiye grail yopatulika ya mphamvu ya lithiamu-ion, koma kufalikira kwake ndikupha. Kafukufuku wamagulu ophatikizika omwe amagwiritsa ntchito calcium-silicon intermediates kapena zokutira kuti athe kuthana ndi kupsinjika ndikupanga zigawo zabwino za SEI akupitilira. Ndikoyamba, koma chemistry yayikulu ikulonjeza. Kudziwa momwe mungapangire zoyendetsedwa bwino, tinthu tating'onoting'ono zitsulo za silicon akhoza kusamutsidwa mwachindunji.

Chachiwiri, kupanga zowonjezera. Kusindikiza ndi zitsulo, makamaka zosunthika monga aluminiyamu kapena titaniyamu aloyi, nthawi zambiri kumafuna deoxidation yeniyeni ndi kukonzanso tirigu mu situ. Powder feedstock yopangidwa ndi miniti, kufalikira kwa yunifolomu kwa ma modifiers opangidwa ndi calcium-silicon kungakhale njira yopita kuzinthu zosindikizidwa bwino. Ndiko kusuntha sitepe yosinthira zinthu kuchokera kusungunuka wambiri kupita ku tinthu ta ufa. Izi zimafuna mawonekedwe osiyana kwambiri a aloyi, zovuta kwa opanga miyambo.

Izi sizinthu zenizeni. Iwo ndi bets. Ndipo amafuna kuti opanga aziganiza ngati opereka mayankho, osati osungunula okha. Zikutanthauza kuyika ndalama mu R&D pazofunsira zomwe sizingakhale ndi msika kwazaka khumi. Kodi makampaniwa ali ndi chipiriro? Ena amatero. Osewera akuluakulu, ophatikizika omwe ali ndi machitidwe abwino okhazikika ali ndi mwayi wowongolera chifukwa amamvetsetsa kale kuwongolera pamlingo wofunikira.

Zowona Zenizeni: Mtengo, Scale, ndi Green Pressures

Tisatengeke. Kwa zonse zomwe zingatheke, dalaivala wamkulu wa calcium silicon kupanga kudzakhala mafakitale achitsulo ndi maziko amtsogolo. Ndipo gawo ili likukakamizidwa kwambiri kuti liwononge mpweya. Mphamvu yopangira ma alloys amenewa ndi yodabwitsa. Tsogolo la 'duo' ili likugwirizana mosagwirizana ndi kubiriwira kwa ng'anjo yamagetsi yamagetsi. Opanga omwe ali m'magawo omwe ali ndi mphamvu zowonjezera, monga Inner Mongolia, akhoza kukhala ndi mwayi wokhalitsa ngati angazigwirizanitse ndi njira zogwirira ntchito.

Mtengo ndi nyundo ina. Mapulogalamu apamwamba ndi otsika mtengo. Battery anode kapena ufa wosindikiza wa 3D sungathe kutenga ndalama zambiri pazinthu zomwe zilipo pokhapokha ngati kudumpha kwa ntchitoyo kuli kodabwitsa. Kukweza mitundu yatsopano, yoyera kwambiri kapena yopangidwa mwapadera kuti muchepetse mtengo ndiye vuto lalikulu. Ndilo chigwa chapamwamba cha imfa kwa zipangizo zamakono.

Ndiye, ndi awiriwa amtsogolo? M’lingaliro lina, zili kale—osati m’njira yodabwitsa imene timalingalira. Udindo wake ngati wofunikira, wothandizira kumbuyo kwa mafakitale oyambira ndi gawo laukadaulo. Chisinthikocho chidzakhala pang'onopang'ono: kusasinthasintha kwapamwamba, zinthu zowonjezera, ndipo mwinamwake, mwinamwake, kutulukira m'munda wapafupi waukadaulo wapamwamba. Mphamvu yaiwisi, monga momwe zimawonekera pagulu la opanga wamkulu-kuchokera silicon manganese ku mawaya apadera - zikuwonetsa kusinthasintha kwazinthu kulipo. Funso ndilakuti ndani angayilumikize ku gulu lotsatira lamavuto.

Kuyimaliza: Maonedwe a Othandizira

Kotero, ndichiyani changa? Kuchotsa calcium ndi silicon monga chuma chakale ndi chosawona bwino. Kuzama kwa kukonza ndi kugwiritsa ntchito chidziwitso chomwe chili mumsika ndi chinthu chofunikira kwambiri. Tsogolo siliri kwenikweni kusintha, koma kukulitsa kwaukadaulo. Ndizokhudza kupititsa patsogolo kumvetsetsa kwazitsulo koteroko kuti athetse mavuto olondola m'madera atsopano.

Makampani omwe amapeza izi, omwe amakhalabe owongolera bwino akamafufuza m'mphepete mwawo - monga omwe ali ndi ma alloy alloy processing ndi mizere yoyesera - ndi omwe amapanga zomwe 'duo' iyi imakhala. Iwo ndi maziko.

Kwa injiniya kapena woyang'anira zogula, phunziro ndikuyang'ana mozama. Osangotchula CaSi 30/60. Mvetsetsani njira yomwe idachokera, kuyesa kumbuyo kwake, ndi kuthekera kwa wopanga kuti agwirizane pavuto. Ndiko komwe m'mphepete mwaukadaulo weniweni ukukulitsidwa, gulu limodzi lolamulidwa nthawi imodzi.
