Micropowder na Green Silicon Carbide: Sabon Ma'auni don Kayan Aiki Masu Inganci da Tanadin Makamashi
I. Menene Ainihin Shi? Me Yasa Ake Kira Shi "Hardcore"?
Da farko, bari mu fahimci menenefoda mai siffar silicon carbide koreshine. Ka yi tunaninsa a matsayin wani nau'in "lu'u-lu'u na wucin gadi." Duk da cewa lu'u-lu'u na gaske bai yi ƙarfi ba, babu shakka yana da ƙarfi sosai. Ana tace shi a cikin tanda mai jure zafi mai zafi sama da digiri 2,000 na Celsius ta amfani da yashi mai siffar quartz, petroleum coke, da sauran kayan masarufi, wanda hakan ya sa ya zama launin kore na musamman.
Yanayin "hardcore" yana bayyana a fannoni uku:
Babban Tauri da Kaifi: Taurin Mohs ɗinsa ya kai 9.2, wanda ya biyo bayan lu'u-lu'u. Wannan yana nufin cewa lokacin yankewa da niƙa, yana aiki kamar ƙaramin haƙori mai kaifi, wanda cikin sauƙi yake "niƙa" ta cikin abubuwa masu tauri da karyewa kamar wafers ɗin silicon na photovoltaic, gilashin sapphire, da lu'ulu'u na piezoelectric.
Tauri Mai Girma, Yana Son Karyewa Maimakon Lanƙwasawa: Tauri kaɗai bai isa ba; yana kuma buƙatar dorewa. Wasu kayan suna da ƙarfi sosai kuma suna rugujewa zuwa foda mai laushi idan aka matse su, wanda hakan ke sa su zama marasa amfani. Micropowder ɗin silicon carbide mai launin kore yana da ƙarfi sosai yayin da yake riƙe da ƙarfi mai kyau. Yana kiyaye siffarsa a ƙarƙashin matsin lamba mai yawa, yana amfani da ƙarfi sosai ga kayan aikin ba tare da ya karye ba.
Mai dorewa a fannin sinadarai kuma mai aiki tukuru: A yanayin zafi na ɗaki, da kyar yake amsawa da duk wani sinadarin acid ko tushe, wanda hakan ke sa shi ya zama abu mai aiki tukuru. Wannan yana nufin cewa a lokacin yankewa, yana guje wa halayen sinadarai da ba a so tare da kayan da ake sarrafawa, yana tabbatar da tsarkin abu. Wannan yana da mahimmanci ga masana'antar photovoltaic da semiconductor, inda tsarki yake da matuƙar muhimmanci.
II. Ingantaccen aiki da kuma adana makamashi—ba wai kawai taken banza ba ne
Zuwa ga ma'anar: Me yasa ake kiransa "sabon ma'auni"? Ta yaya aka nuna waɗannan ingantattun ayyuka da tanadin makamashi musamman? Bari mu yanke hukunci kan abubuwan da ba su dace ba mu kwatanta wasu yanayi masu amfani.
Yanayi na 1: "Masu Yanke Daidaito" na Wafers na Silicon Photovoltaic
Lao Zhang, ka fi sanin wannan.Kayan siliconYana da tsada sosai a kwanakin nan. Rage shi da sirara yana haifar da ƙarin wafers, yana rage farashi. Duk da haka, wafers ɗin silicon masu sirara suna da sauƙin karyewa, suna buƙatar mafi girman ƙa'idodi don fasahar yankewa da gogewa. Micropowder ɗin silicon carbide mai launin kore, tare da siffar barbashi iri ɗaya da gefuna masu kaifi, yana haifar da ƙarfi mai ƙarfi da daidaito yayin aikin yankewa. Sakamakon:
Ingantaccen yankan itace: Ana iya yanke ƙarin wafers a cikin lokaci ɗaya, ko kuma a ƙara saurin yankan.
Ingancin saman da aka yanke: Layin lalacewar saman wafers ɗin silicon da aka yanke ƙanƙanta ne, kuma TTV (bambancin kauri gaba ɗaya) ƙasa ne, wanda ke haifar da ƙaruwar yawan amfanin ƙasa cikin sauri.
Ƙarancin asarar kayan aiki: Yankewa daidai yana haifar da ƙarancin asarar kerf, yana rage ɓatar da kayan silicon masu tsada. Ga jarin da suka wuce ɗaruruwan miliyoyin yuan, wannan tanadi yana da yawa.
Yanayi na 2: "Ɗan wasa mai juriya" na sarrafa saffir
Yawancin murfin kyamarar wayarka da gilashin agogo masu tsada an yi su ne da saffir. Sapphire ya fi gilashi wahala kuma yana da matuƙar wahala a sarrafa shi. Amfani da goge-goge na yau da kullun na iya rage shi bayan ɗan lokaci, wanda hakan ke rage inganci sosai. Duk da haka, micropowder ɗin silicon carbide mai launin kore, godiya ga kyakkyawan juriyarsa ta lalacewa, yana riƙe da kaifi mai kaifi na tsawon lokaci, yana tsawaita tsawon rayuwarsa. Wannan yana nufin:
Ana rage yawan canje-canjen gogewa, ana rage lokacin aiki, kuma ana inganta ingancin samarwa.
An rage farashin sarrafawa gaba ɗaya. Duk da cewa farashin kowace tan na iya zama mafi girma, ƙaruwar inganci da raguwar abubuwan amfani a zahiri suna rage jimlar kuɗin. Wannan gaskiya ne "ceton makamashi."
Yanayi na 3: Faɗaɗawa Zuwa Duniya Mai Faɗi
Ƙarfinsa ya wuce wannan. Ƙara shi zuwa kayan da ke hana ruwa shiga zai iya tsawaita rayuwar murhu da inganta rufin rufi, yana adana makamashi yadda ya kamata a cikin tanderun masana'antu masu amfani da makamashi. A cikin kayan haɗin gwiwa, a matsayin ƙarfafawa, yana sa kayan aikin su fi juriya ga lalacewa da ƙarfi, yana faɗaɗa zagayowar kula da kayan aiki - kuma wani nau'in adana makamashi ne da aka ɓoye. Ko da a cikin masana'antar sararin samaniya, yana da mahimmanci don niƙa daidai na wasu kayan aikin yumbu na musamman.
III. Hanya Mai Gaba: Mafi Kyau, Mafi Inganci, Mafi Hankali
Ba shakka, micropowder mai launin kore na silicon carbide ba cikakke ba ne. Domin tabbatar da wannan "sabon ma'auni," masana'antunmu dole ne su yi aiki tukuru a fannoni da dama:
Ci gaba da gyaran girman barbashi: Masana'antu na ƙasa suna buƙatar ƙarin daidaito. Muna buƙatar samar da ƙananan foda tare da rarraba girman barbashi da kuma siffar barbashi akai-akai (mafi kyawun isomorphism). Wannan kamar ƙungiyar sojoji ne ke tafiya tare suna tafiya a cikin alkibla ɗaya don ingantaccen tasirin yaƙi. Dole ne a sarrafa abubuwan da ke cikin manyan da ƙananan barbashi (abin da ake kira "maras kyau" da "mai kyau") sosai; in ba haka ba, yankewa zai haifar da ƙage a kan aikin da kuma raguwar inganci.
Fasahar gyaran fuska: Gyaran fuska naƙwayoyin micropodaiki ne mai matuƙar fasaha. Misali, haɓaka dacewarsu da ruwan yankewa da kuma abubuwan ɗaure resin na iya ƙara haɓaka ingancin yankewa da aikin samfur. Kamar shafa mai a kan takobi ne—ba wai kawai yana kaifafa gefensa ba har ma yana ƙara ƙarfinsa.
Gyaran Tsarin Samarwa: Duk da cewa abu ne mai adana makamashi, shin tsarin samar da shi zai iya zama mai inganci ga makamashi da kuma dacewa da muhalli? Misali, amfani da makamashi a cikin tanderun narkewa, tattara ƙura yayin niƙawa da tantancewa, da kuma sake amfani da ruwa - duk waɗannan fannoni ne da ke buƙatar ci gaba da haɓakawa da sake maimaitawa a cikin masana'antarmu. Muna ƙoƙarin ƙirƙirar kayan kore a duk tsawon rayuwarsu.
Ga waɗanda muke cikin masana'antar kayan aiki, labarin ƙaramin foda mai launin kore na silicon carbide ya fara. Yin amfani da shi ya fi kyau, cikakken bayani, da kuma wayo shine babban gudummawar da muke bayarwa wajen haɓaka masana'antar China don inganci da kiyaye makamashi.
