Ukusebenza Okumangalisayo kwe-Alumina Powder kwiZixhobo zoKubona
Xa kufikwa kwi-alumina, abantu abaninzi banokucinga kuqala ngezo zinto zimhlophe, ziqinileyo zokwenza imveliso, ezibonakala ngathi azinxulumananga nobuchwepheshe obuphezulu bokukhanya. Nokuba ukholelwe okanye awukholwa, oko kukungakunaki ngokupheleleyo. Wakuba uyiqondile kwaye uyiqhelile, ingakumbi ekufezekiseni ubunyulu obugqithisileyo kunye nolawulo oluchanekileyo kwimo yempuphu, indima yayo kwihlabathi lokukhanya iyamangalisa ngokwenene, nto leyo eyenza ukuba ibe "yindlu enamandla engaphantsi."
I. Ukusuka “kwindoda enzima” ukuya “ecacileyo”: Utshintsho oluhle kakhulu
Sonke siyayazi loo ntoi-aluminainegama elidumileyo—i-corundum, enobunzima be-Mohs obuyi-9, ilandela idayimani kuphela, nto leyo eyenza ukuba ibe “ngumntu oqinileyo.” Liyinxalenye ephambili yamatye anqabileyo axabisekileyo afana nesafire kunye neruby. Nangona kunjalo, kwizinto ezibonakalayo, eyona nto iphambili ayikokuqina, kodwa “ukucaca”—ukudlulisa ukukhanya okuhle, ubumsulwa, kunye nokuzinza.
Kulapho ke iteknoloji ingena khona. Ngeenkqubo zokulungiselela eziphambili, ezinje ngokutshiswa okulawulwayo kwe-aluminium ecocekileyo kakhulu kunye neendlela ezikhethekileyo ze-hydrolysis, sinokufumana i-ultrafine kunye ne-ultra-uniform.umgubo we-aluminaenobunyulu obufikelela kwi-99.99% okanye i-99.999%. Musa ukuyithatha lula le nkqubela yobunyulu; kufana nokuguqula amanzi omlambo amdaka abe ngamanzi acacileyo entwasahlobo, ukunciphisa ubumdaka ukuya kumanqanaba angaphantsi kakhulu. Sisebenzisa le powder icocekileyo njengesixhobo sokuqala, emva kokubumba nokuthambisa, singalungisa ii-alumina ceramics ezinokukhanya okugqwesileyo.
Le ceramic ayiseyiyo "indoda erhabaxa" engacacanga, kodwa "yindoda ekhanyayo" okanye ephantse ibonakale. Xa ukukhanya kukhanya kuyo, ivumela ukukhanya okubonakalayo nokubonakalayo ukuba kudlule, ngelixa igcina amandla aphezulu, ubulukhuni obuphezulu, ukumelana nokugqwala, kunye nokumelana nobushushu obuphezulu kwe-alumina. Olu phawu "lweenjongo ezimbini" luyivumele ukuba izinze ngokukhawuleza kusapho lwezinto ezibonakalayo.
II. Ukusetyenziswa Okusebenzayo Kutyhila Amandla Okwenene: Iintsika Zeendawo Ezininzi Eziphambili
Intetho ibiza kancinci. Ukusebenza okugqwesileyo kweumgubo we-aluminakwizixhobo ezibonakalayo sisiphumo sovavanyo lwehlabathi lokwenyani. Makhe sijonge imizekelo embalwa kubomi bethu bemihla ngemihla nakumacandelo emizi-mveliso ukubonisa oku.
1. Izibane zeSodium: “Izixhobo Ezicacileyo” Ezikhanyisa Ubusuku
Uninzi lwezibane ezikhanyayo ezidolophini ebusuku zizibane zesodium ezinoxinzelelo oluphezulu. Ngaba uqaphele ukuba iityhubhu ezikhanyayo aziyoglasi eqhelekileyo, kodwa yityhubhu yeseramikhi ekhanyayo? I-Alumina ceramic yeyona nto iphambili apha.
Kutheni kunjalo? Okokuqala, umphunga wesodium uyatsha kakhulu xa ushushu kakhulu kwaye uxinezelekile; iglasi eqhelekileyo ayinakumelana nayo kwaye iya “kufa” kwiintsuku nje ezimbalwa.I-Alumina ceramicKwelinye icala, ayimelani nokugqwala ngokwemvelo, ihlala iqinile xa ijongene “nomceli mngeni” womphunga wesodium. Okwesibini, kufuneka isebenze ngokuzinzileyo ixesha elide kumaqondo obushushu afikelela kumawaka eedigri zeCelsius, apho ukumelana nobushushu obuphezulu be-alumina kuyanceda. Okubaluleke kakhulu, kufuneka ivumele ukukhanya okubonakalayo kudlule ngokufanelekileyo ngelixa ngaxeshanye ingasabeli kumphunga wesodium. Njengoko ubona, amandla aphezulu, ukumelana nokugqwala okuphezulu, ukumelana nobushushu obuphezulu, kunye nokukhanya okukhanyayo—ezi mfuno zinzima xa zidibene zenza ii-ceramics ze-alumina zibe lolona khetho lusebenzayo. Isiseko sayo yonke le nto yi-alumina powder ekhethwe ngononophelo kwaye ilungiselelwe ngononophelo.
2. Iifestile ze-Infrared kunye neeFairings: "Amehlo Akhanyayo" eeMissile kunye neeDetectors
Kwimimandla yomkhosi neyeenqwelo-moya, abantu abafuna imijukujelwa kunye neenkqubo zokubona i-infrared zezithuthi eziphakamileyo nezihamba ngesantya esiphezulu zonke zifuna ikhaka elikhuselayo, okanye "ifestile" okanye "ifairing." Iimfuneko zoku ziphezulu nangakumbi: akufuneki nje kuphela ukuba yomelele ngokwaneleyo ukumelana nokukhukuliseka komoya ohamba ngesantya esiphezulu kunye nempembelelo yamaconsi emvula nothuli, kodwa kufuneka ikwadlulise ukukhanya kwe-infrared kwiiwavelength ezithile, okuvumela abafumani bangaphakathi ukuba "babone" ihlabathi langaphandle.
Kulapho ke i-alumina ceramics ecacileyo okanye ekhanyayo iphinda ivele khona. Ubulukhuni bayo banele ukumelana nokukhukuliseka kweendawo ezinobungozi, kwaye ukusebenza kwayo kokusasazwa kwe-infrared kugqwesile, ingakumbi kwiibhendi ze-infrared eziphakathi nakude. Khawuthelekelele i-missile ebhabha esibhakabhakeni esikhulu sasebusuku. "Amehlo" ayo yi-fairing eyenziwe nge-alumina ceramic, ekhusela inkqubo yangaphakathi yokubona kakuhle kwaye ikhokela i-missile ngokuchanekileyo kwithagethi yayo. Olu xanduva lunzima lungaphaya kwamandla ezixhobo eziqhelekileyo.
3. IiSubstrates kunye nezixhobo eziphezulu: "I-Solid Stage" yeHlabathi le-Integrated Circuit Optical
Ngenxa yokuqhubela phambili kwetekhnoloji, izixhobo ezifana nee-LED, ii-laser, kunye nee-optical sensors zihlala zifuna "isigaba" esizinzileyo, esithe tyaba, esikhuselayo, nesiqhuba ubushushu ukuze zisebenze. Ii-Alumina ceramic substrates zezona "sigaba" zifanelekileyo.
Ngokufanayo, umgangatho wale "nqanaba" uxhomekeke ngokuthe ngqo kumgangatho "wezitena" zalo—umgubo we-alumina. Ubunyulu obuphezulu bomgubo bubangela umphezulu ogudileyo, ofana nesipili kwi-substrate exotyulweyo, nto leyo enciphisa ukubonakaliswa kokukhanya kunye nokuphazamiseka kokuhambisa; amasuntswana afanayo kunye nomgubo ocolekileyo aqinisekisa isakhiwo esixotyulweyo esixineneyo, esingenazo iimbobo kunye nezinye iziphene, nto leyo ebangela ukuba kubekho ubushushu obuhle kakhulu kunye nokuqhuba kobushushu. Ukujikeleza okuntsonkothileyo kwiifowuni zethu eziphathwayo kusenokuba kukho ngenxa ye-alumina ceramic substrates, nangona zihlala zifihliwe. III. Kutheni kunjalo? Masithethe "Ngempumelelo" Yayo Engaphakathi
Emva kokuba sixoxe ngeendlela ezininzi zokusetyenziswa, makhe siphinde sijonge ukuba kutheni i-alumina powder ibalasele kangaka. Ekugqibeleni, kungenxa yoluhlu lweempawu zayo ezintle zangaphakathi, ezihlangabezana ngokugqibeleleyo neemfuno eziphambili zezinto ezibonakalayo:
Ukusebenza Kokukhanya Okulawulekayo: Ngokulawula ubunyulu bomgubo, ubungakanani bamasuntswana, kunye nenkqubo yokusila, isalathisi sokudlulisa kunye nokurhawuzelela kwemveliso yokugqibela yeseramikhi kwi-ultraviolet, ebonakalayo, kunye neebhendi ze-infrared zinokulawulwa ngokuchanekileyo.
Amandla Oomatshini Angaqhelekanga: Ubunzima obuphezulu, amandla aphezulu, kunye nokuqina okuphezulu kwenza ukuba ikwazi ukumelana nobunzima kwaye iphile ixesha elide.
Iimpawu zeekhemikhali ezihlala ziqinile: Izinzile kakhulu, ayisebenzi lula kwii-asidi, ii-alkali, iityuwa, kunye nezinye izinto ezininzi zeekhemikhali, kwaye inokumelana neendawo ezahlukeneyo ezinzima.
Uzinzo Oluhle Kakhulu Lobushushu: Njengoko iqondo lokunyibilika lingaphezulu kwama-2050℃ kunye ne-coefficient ephantsi yokwandiswa kobushushu, imo kunye nobukhulu bayo azitshintshi phantse kumaqondo obushushu aphezulu, kwaye ikwanokumelana okuhle nokutsha kobushushu (oko kukuthi, ayoyiki utshintsho olukhawulezileyo lobushushu).
Intshatsheli yokukhusela umbane: Ukumelana kwayo okuphezulu kuyenza ibe yi-insulator ebalaseleyo, ebalulekileyo kwiinkqubo ezidibeneyo ze-optoelectronic.
Njengoko ubona, ezi mpawu zidibeneyo zenza kubonakale ngathi zenzelwe ukusetyenziswa kwezixhobo ezininzi ezikhethekileyo ze-optical. Ngaphezu koko, xa kuthelekiswa nezinye izinto ze-optical ezifana ne-sapphire single crystals, ukulungiselela ii-ceramics ezibonakalayo ezivela kwi-powder kunika iingenelo ezibalulekileyo kunye nokuguquguquka ekulawuleni iindleko kunye nokwenziwa kweemilo ezinzima kunye neemveliso ezinkulu. Ngoko ke, ungasayi kuyithatha lula i-alumina powder!
