Micropowder na Green Silicon Carbide: Tauraron da ke Tashi na Abubuwan da ke Kare Mu Masu Kyau
A yau, bari mu ci gaba da tattaunawarmu game da wani babban ɗan wasa a cikin iyali mai tsauri—foda mai siffar silicon carbide kore. Waɗanda muke cikin wannan masana'antar suna kiransa da "Hulk" a ɓoye, kuma ba ma tsammanin sunan yana da ban dariya; iyawarsa ta yi daidai da wannan taken. Kwanan nan mun tattauna farin alumina da aka haɗa sosai; kamar ƙwararren ma'aikacin kotu ne, yana samar da aiki mai kyau da tsabta. Amma "Hulk" na yau ya fi kama da janar mai ja gaba wanda ke shiga yaƙi, ƙwararre a cikin yaƙe-yaƙe masu wahala da kuma magance ƙalubale mafi wahala. Me yasa ake kiransa "tauraro mai tasowa"? Dalili na farko shine "taurinsa."
Koren silicon carbide yana da mafi girman tauri a tsakanin abrasives na yau da kullun, tare da taurin Mohs na 9.5, kaɗan ƙasa da lu'u-lu'u. Kada ku raina wannan bambancin 0.5 sama da hakafarin alumina mai haɗe; idan ana mu'amala da wasu kayan da suka yi tauri sosai, yana kawo babban canji. Sabbin kayan aiki suna ci gaba da fitowa: yumbun silicon carbide, nitride na aluminum, gilashin sapphire, wafers na silicon photovoltaic, simintin carbide - kowannensu ya fi ta ƙarshe ƙarfi. Yin amfani da goge-goge na yau da kullun kamar goge dutse da zanen ƙarfe ne - yana da wahala kuma ba shi da tasiri.
Amma tare da micropowder mai launin kore na silicon carbide, daidai ne. Gefen sa masu kaifi suna aiki kamar ƙananan kayan aikin yanke lu'u-lu'u, suna "taunawa" da kyau ga waɗannan kayan aiki masu wahala. Musamman a masana'antar photovoltaic, yanke waɗannan ingots ɗin silicon monocrystalline masu tauri da ƙarfi, za ku ga ana amfani da shi a cikin babban ɓangaren layin samarwa. Ba tare da shi ba, farashi da ingancin samarwa ba za a rage su ba. Wannan shine abin da kuke kira "abu ɗaya yana rinjayar wani."
Bugu da ƙari, ƙarfin thermal ɗinsa yana da kyau ƙwarai.
Wannan kayan da kansa kyakkyawan mai sarrafa zafi ne. Wannan babban fa'ida ne a cikin tsarin niƙa. Ka yi tunanin, niƙa mai sauri yana haifar da zafi mai yawa nan take. Idan wannan zafi ba zai iya ɓacewa ba kuma ya makale a cikin kayan aikin, to abin bala'i ne: saman kayan aikin yana da saurin "ƙonewa" da fashewa; sassan ƙarfe na iya rufewa, suna canza taurinsu; kuma girman abubuwan da aka gyara na iya zama ba daidai ba saboda faɗaɗa zafi da matsewa.
Foda mai launin kore na silicon carbide yana aiki kamar "ƙaramin tsarin watsa zafi," wanda aka gina a ciki, yana fitar da zafi cikin sauri daga yankin niƙa, yana rage zafin yankin sarrafawa yadda ya kamata. Wannan yana rage lalacewar kayan aikin da ke haifar da zafi mai yawa, yana tabbatar da ingancin sarrafawa. Wannan kusan siffa ce mai mahimmanci, musamman ga kayan aiki da sassan da ke da matuƙar saurin kamuwa da zafi.
Bugu da ƙari, kayan aikinsa na "kaifi kai" yana sa aikin ya kasance mai kaifi koyaushe.
Gilashin gogewa masu kyau ba abu ne da ake amfani da shi sau ɗaya kawai ba; suna buƙatar su daɗe.barbashi na silicon carbide koresuna da tauri da karyewa, a ƙarƙashin ƙarfin niƙa, ƙwayoyin da suka lalace za su ruguje, suna fallasa sabbin gefuna masu kaifi don ci gaba da aiki. Wannan halayyar ana kiranta "kaifi kai."
Wannan yayi kama da amfani da fensir na inji; idan ya yi duhu, sai ka sake danna shi, sai sabon fensir ya fito don ci gaba da zane. Wannan yana nufin cewa a duk tsawon aikin, ikon yankewa yana ci gaba da zama sabo da ƙarfi, ba tare da ya yi duhu ba akan lokaci. Ingancin sarrafawa yana da ƙarfi, kuma ingancin saman kayan aikin iri ɗaya ne, yana guje wa yanayin da ingancin ya inganta a farko amma ya lalace daga baya. Wannan yana da mahimmanci ga samarwa ta zamani, babba, ta atomatik.
Bari in ba ku labari na gaskiya.
A bara, wata masana'anta da ke yin bututun injin mai inganci ta tuntube ni. bututun su an yi su ne da yumbu na musamman masu tauri sosai. Yin amfani da goge-goge na yau da kullun don sarrafawa ko dai bai yi inganci ba kuma yana da tsada, ko kuma ingancin saman bai yi daidai ba, sau da yawa yana nuna ƙananan fasa. Daga baya, sun yi ƙoƙarin amfani da micropowder na silicon carbide mai kore don niƙa da gogewa mai kyau, kuma sakamakon ya kasance nan take. Ba wai kawai inganci ya ƙaru da kashi 30-40% ba, amma mafi mahimmanci, a ƙarƙashin na'urar hangen nesa, layin lalacewa akan saman aikin kusan ba a iya gani, kuma ƙimar yawan amfanin ƙasa ta yi tashin gwauron zabi. Daga baya shugabansu ya yi kuka, "Da alama aikin bai yi wahala ba; kawai ba mu zaɓi kayan aiki da suka dace ba."
Ka gani, wannan shine ƙarfin "Hulk" - a fannin ƙwarewa, yana iya magance matsalolin da wasu ba za su iya ba.
Ba shakka, wannan "janaral mai ƙarfin hali" ba shi da wani irin yanayi. Duk da cewa yana da wahala, amma ƙarfinsa ba shi da kyau, wanda hakan ke sa ya yi rauni. Saboda haka, idan ana mu'amala da wasu kayan aiki masu ƙarfi, kamar wasu ƙarfe, ba zai yi aiki kamar farin alumina da aka haɗa da ƙarfi ba. Bugu da ƙari, launin kore mai launin shuɗi ya fito ne daga ƙaramin adadin ƙazanta; a cikin takamaiman hanyoyin goge semiconductor waɗanda ke buƙatar tsantsar sinadarai, har ma ana iya buƙatar kayan aiki masu tsabta. Amma wannan ba ya rage matsayinsa na iko wajen sarrafa kayan aiki masu tauri da masu rauni ba.
To me yasa ake ɗaukarsa a matsayin "tauraro mai tasowa"? Kawai kalli yanayin masana'antu na yanzu da na gaba: semiconductor na ƙarni na uku (silicon carbide, gallium nitride), sabon makamashin photovoltaic, yumbu na sararin samaniya, gilashin gani mai inganci… da yawa daga cikin waɗannan masana'antun fitowar rana sun dogara ne akan kayan sarrafawa na asali waɗanda suke da tauri da rauni. Micropowder na silicon carbide mai launin kore yana ɗaya daga cikin kayan aiki mafi dacewa da inganci don magance waɗannan matsalolin ƙalubale.
Ƙarfinsa yana ƙaruwa tare da waɗannan masana'antu masu fasaha. Muddin waɗannan masana'antu suka bunƙasa, za a ci gaba da buƙatar ƙaramin foda mai launin kore mai silicon carbide. Masana'antarmu ta abrasion kuma tana ci gaba da bincike kan yadda za ta sa ƙwayoyinta su zama iri ɗaya da kuma yadda za a daidaita su da kyau, ta yadda za su iya haskakawa sosai a wannan zamani mai cike da albarka.
