Graphene carbon yas alloy tshav kub dissipation tov debuted ntawm Guangya Exhibition thawj zaug, ua lub hom phiaj ntawm cov neeg tuaj saib
Thaum graphene siv nyob rau hauv qhov chaw ntawm LED tshav kub dissipation, dab tsi ntawm sparks nws yuav tsoo nrog? Nyob rau ntawm Guangya Exhibition ib lub lim tiam dhau los, peb pom tias muaj lub rooj muag khoom hauv Hall 10.2 nthuav tawm ntau yam tsis yog txhuas radiators, uas nyiam cov neeg tuaj koom ntau hauv tsev thiab txawv teb chaws. Ib lub rooj muag khoom kub tshaj plaws nyob rau hauv lub exhibition.
Raws li cov neeg ua haujlwm nyob rau ntawm qhov chaw, cov radiators yog tsim los ntawm cov khoom siv tshiab-" carbon-yas alloy". Carbon-yas alloy yog ib hom tshiab ntawm ultra-siab thermal conductivity cov khoom sib xyaw ua ke ntawm graphene thiab polymer cov ntaub ntawv. Nws yog tus kheej tsim los ntawm Xiamen Kaina Graphene Technology Co., Ltd. raws li nws tus thawj thib rau tiam core technology ntawm lub cev thiab txhua yam exfoliation graphene.
Nws tau nkag siab tias graphene yog ob-dimensional nanomaterial nrog hexagonal honeycomb lattice tsim los ntawm carbon atoms thiab SP2 hybrid orbitals. Xyoo 2004, University of Manchester Andrei Heim thiab Konstantin Novosenov thawj zaug pom graphene. Thaum Lub Kaum Hli 2010, lawv tau sib koom ua ke yeej Nobel nqi zog hauv Physics rau lawv cov kev tshawb fawb tau zoo hauv cov ntaub ntawv graphene. Raws li cov khoom siv ua haujlwm zoo tshaj plaws, graphene suav nrog hauv phau ntawv qhia kev txhim kho ntawm kuv lub tebchaws' s" Ua nyob rau hauv Tuam Tshoj 2025". Lub thermal conductivity ntawm graphene yog siab li 5300W / m·K, uas yog ntau dua li cov khoom siv hluav taws xob cov khoom siv hluav taws xob xws li tooj liab (li 400W / m·K) thiab txhuas (li 240W / m·K). Lub ultra-siab thermal conductivity thiab lwm yam khoom zoo heev ua rau graphene ib qho kev cog lus rau tiam tom ntej tshav kub dissipation thiab thermal tswj cov khoom, thiab nws muaj ntau yam kev siv nyob rau hauv lub tshav pob ntawm high-power LED teeb pom kev zoo.
Xiamen Kaina tau sau npe thiab tsim 5 lub hlis ua ntej graphene yeej qhov khoom plig Nobel. Nws tsis yog tsuas yog ib lub tuam txhab graphene ntxov tshaj plaws tsim nyob rau hauv Suav teb, tab sis kuj yog lub teb chaws high-tech enterprise tshwj xeeb hauv graphene R& D, ntau lawm thiab muag khoom. Kev lag luam-kev ua lag luam thib rau-tiam lub cev tshuab tev graphene core thev naus laus zis tau txo qis tus nqi ntawm KNG graphene thiab tau dhau los ua tus thawj coj hauv kev npaj lub cev ntawm graphene.
Tom qab xyoo dhau los nag lossis daus thiab kev loj hlob, Xiamen Kaina tau tsim cov qauv kev lag luam ntawm" ib qho nyuaj thev naus laus zis thiab ob qhov kev siv tau zoo": graphene siv los ua cov thev naus laus zis nyuaj, thiab cov thermal conductivity carbon-yas alloys. tau tsim nyob rau hauv cov nqe lus ntawm tshav kub conduction kev lag luam daim ntawv thov. LED tshav kub dissipation yog thawj zaug, ua rau graphene thermal tswj kev siv; Hauv kev lag luam kev lag luam kev lag luam, kev tsim cov khoom siv hluav taws xob zoo graphene rau cov roj teeb lithium tau coj mus rau kev siv zog tshiab ntawm graphene.
Carbon-yas alloy muaj cov yam ntxwv ntawm cov khoom siv qis, tsis muaj kev ua haujlwm thib ob uas yuav tsum tau txhaj tshuaj molding, thiab qhov hnyav yog ntau dua 40% sib dua li aluminium alloy, uas tuaj yeem ua rau muaj txiaj ntsig zoo rau cov neeg siv khoom. Tsis tas li ntawd, lub super corrosion kuj ntawm carbon yas alloy, tom qab 2016 teev ntawm ntsev tsuag raug (50g / l ntsev dej concentration, 35 °, saturated cua kub 47 ° [GB / T 10125-2012]), nws cov cua kub dissipation kev ua tau zoo. tsis tshwm sim. Qhov kev hloov no ua rau cov pa roj carbon-yas alloy radiator tsis xav tau kev pleev xim kim, electroplating lossis anodic oxidation theem ob ua haujlwm zoo li aluminium alloy kom ua tiav kev ruaj ntseg zoo dua hauv qhov hnyav.
Nws tau tshaj tawm tias txij li Xiamen Kaina tau tsim thawj tiam ntawm carbon-yas alloy cov ntaub ntawv nyob rau hauv 2018, nws tau siv LED tshav kub dissipation ua thawj zaug. Nws tau siv nyob rau hauv kev lag luam teeb pom kev zoo (spotlights, downlights, taug qab teeb, thiab lwm yam), engineering teeb pom kev zoo (txoj kev teeb, kev vam meej tseem ceeb tau ua nyob rau hauv cov kev siv ntawm industrial thiab mining teeb, dej nyab teeb, integrated txoj kev teeb vaj tse, thiab lwm yam) thiab tsheb teeb. Tam sim no, lub thib ob tiam ultra-high-strength carbon-yas alloy khoom siv tshuab tau matured, thiab cov khoom tau tsim ob loj series ntawm general-lub hom phiaj thiab txhim khu kev qha cov khoom. Cov qauv ntawm" hloov txhuas nrog yas" tau tshwm sim hauv kev lag luam ntawm LED, cov khoom siv hluav taws xob, khoom siv sib txuas lus, thiab kev tswj hwm kev lag luam. sib.
