1. Isakhelo seMichiza yeAlumina eSpherical

1.1 Yintoni kanye kanye IAlumina eSpherical?

IAlumina eSpherical imele ukutsiba kwe-quantum kwizinto zolawulo lwe-thermal- uhlobo olwenziwe ngononophelo lwe-aluminiyam oxide (Al2O5) yatshintshwa yaba yinto engenasiphako, imijikelo efanayo ngeendlela ezintsonkothileyo zokucoca. Ngokungafaniyo nomgubo we-alumina ongaqhelekanga ophuhlisa ukusetyenzwa kwamaphupha amabi kunye nokusebenza okungahambelaniyo, le morphology engqukuva kukuphunyezwa kwesayensi yemveliso. Asinto nje yokuzalisa; sisisombululo sohlaziyo esenziwe ukusombulula omnye weyona mingeni ikhathazayo yobushushu kwiinkqubo zombane ezisebenza kakhulu kunye neenkqubo zoshishino. Ifomu engqukuva isusa imiphetho ejijekileyo ebangela imfumba, izikhonkwane ezityebileyo, kunye namanqaku abuthathaka kwimidibaniso- ukuhambisa ukulinganisa okungenamthungo kunye nokufana okungahambelaniyo. Olu ayilonkqubela phambili eyongezelelweyo; lutshintsho lweparadigm oluxhobisa abayili ukutyhala imida ngaphandle kwemvume.

1.2 Wenza ntoni IAlumina eSphericalUlwakhiwo lweMichiza lubonakala ngathi?

Umlingo uxhomekeke kulwakhiwo lwayo olusulungekileyo lwe-alphaphase crystalline (Al2O6), eyilwe ngenkuthalo ibe yimijikelo egudileyo, engenasiphako. Le latticework yekristale ikhuselekile ngokwendalo ngokwendalo, inert ngokwekhemikhali, kwaye ikhuselekile ekonakaleni kumaqondo obushushu angaphezu kwe-1,600 °C. Amaqhekeza angqukuva abandakanya umphezulu ongaguquguqukiyo, oqhele ukwenziwa ngonyango olukhethekileyo lomphezulu olukhulisa ukuhambelana neepolymers, i-epoxies, kunye neeporcelain. Okubaluleke kakhulu, ukungabikho kwemiphetho ebukhali kuthintela uxinzelelo lwangaphakathi kunye nezinto ezixhalabileyo kwii-composites, ziqinisekisa iindlela ezihlala zishushu. Oku kuchaneka kweathom akuyonto nje entsonkothileyo- iyimfuneko ukuze kuphunyezwe ulungelelwaniso olunzima phakathi kwe-thermal conductivity kunye nokugqunyelelwa kombane. Waba yintoni umphumo? Isixhobo esingafezekisiyo iinkcukacha kuphela- siyabodlula ngokuthembeka okungagungqiyo.

2. Iimpawu eziphambili zeAlumina

2.1 Ziintoni iiPropati zoMzi neMichiza yeAlumina eSpherical?

I-Alumina eSpherical ineendidi ezoyikekayo zeendawo zokuhlala ezixhathisa izithethe zecandelo. Ngokwenyama, inika ubunzima be-Mohs ye-9 (ukwenza ukuchasana kwe-abrasion ethile), i-coefficient yokwandisa i-thermal ephantsi (7- 8 × 10 ⁻⁶/ ° C), kunye noluhlu lwe-thermal conductivity ye-25- 35 W / mK- ngokumangalisayo ngaphezu kwe-insulators ezisisiseko ezifana ne-silica. Ngokomchiza, ayizinzi, ikhuselekile, kwaye iyakhusela ngombane (ukuqina kwedielectric> 20 kV/mm), iyenza inganyangeki kwiiasidi, iziseko, kunye nobushushu obuphezulu. Ubume bayo obungqukuva bunciphisa kakhulu i-viscosity kwii-composites, okwenza kube lula ukulayisha okungaqhelekanga kwesihluzi (ukuya kuma-70%) ngaphandle kokubeka esichengeni ukuqhubekeka. Olu ayilophuculo nje lwemveliso- lutshintsho-mdlalo kulawulo lobushushu.

5. I-Golden Equilibrium: iSpherical Alumina's HighFiller Ratio Breakthrough

Ubukrelekrele bokwenyani be-Alumina eSpherical buxhomekeke ekukwazini kwayo ukuhambisa ukuhanjiswa kwe-thermal kunye nokugquma kwireyishini eziphezulu zokuzalisa- ukusombulula eyona ngxaki izingisayo yecandelo. Izihluzi zemveli zifuna i-tradeoffs engathandekiyo: iintsimbi ziqhuba ubushushu kodwa zibangela iisekethe ezimfutshane, ngelixa izigqumatheli zifana ne-silica dini esebenza ngokufanelekileyo kwe-thermal. I-Alumina eyiSpherical iyayichitha le paradigm. Ifom yayo ejikelezayo iphuhlisa inethiwekhi ye-thermal engqingqwa, edibeneyo ye-thermal kwi-65-70% yokulayisha i-filler, eyenza i-thermal conductivity ye-22- 28 W / mK ngelixa igcina ukuhlukaniswa kombane ngokupheleleyo.

Le asiyomfundo- ingqinwe emsebenzini. Kwizixhobo ze-LED ezinamandla amakhulu, i-Spherical Alumina idibanisa amanqanaba okushisa aphantsi okusebenza nge-18 ° C xa kuthelekiswa neyeza-based-silica-based remedies, ukwandisa ixesha lokuphila ngama-40% kunye nokuphelisa ukuvalwa kwe-thermal. Kwiipakethe zebhetri yemoto yombane, yenza ukuba i-conditioning ye-air conditioning encinci, ilula kwaye iphephe ukutshisa ngaphandle kokongeza ubunzima. Iimpembelelo zibanzi: izixhobo zombane zinokuba ncinci, zikhawuleze, kwaye zibe namandla ngakumbi- ngaphandle kwemida yobushushu.

Iinjineli akusafuneki ukuba zikhethe phakathi kokusebenza kunye nokhuseleko kunye nokhuseleko. I-Alumina eSpherical ibonelela ngokulingana kwegolide- inkonzo ehambelanayo apho ukusebenza kwe-thermal kunye nokhuseleko lombane kuhlala kunye. Le asiyonto nje; sisivuseleli sokuqhubela phambili esivula imida emitsha kuyilo.

Yamkela ulungelelwaniso. Yamkele impumelelo. I-Alumina eSpherical ayilokamva- lukhetho obusoloko ululindile.
