Iindlela Ezininzi Zokusebenzisa Umgubo We-Alumina Kwishishini LeeMoto
Ngena ngaphakathi nakweyiphi na imoto yanamhlanje kwaye uza kufumanaumgubo we-alumina yenza imisebenzi emininzi ngokuthula, kodwa ayibonwa rhoqo ngabathengi. Namhlanje, masiphakamise i-hood size sibone indlela le mpuphu emhlophe ethatha inxaxheba ngayo ngokunzulu kwintshukumo "yomzimba wonke" wemoto.
Ⅰ. "Amathambo Aqinileyo" eeBrake Pads
“Iibhuleki ezibuthathaka? Kusenokwenzeka ukuba izinto zokungqubana azinzima ngokwaneleyo!” watsho ingcali kwifektri yeebhuleki ngelixa ivavanya iibhuleki. Amandla ayo ayamangalisa: ukongeza i-3%-5% kuphela kwizinto zokungqubana kunokunyusa kakhulu ubunzima bomphezulu webhuleki. Kufana nomaleko omncinci wezixhobo, okuthintela ukuba ingaguquki okanye iwe phantsi kokungqubana okushushu kakhulu. Idatha evela kwiHangzhou Jikang New Materials ibonisa ukuba ukongezwa kwesi sithako kuphucula ukumelana nokuguguleka kwebhuleki ngaphezulu kwe-15%, okwenza kube sisixhobo esonga iindleko zeeteksi ezinokuqala nokuma rhoqo.
Ngaba ingcono na ngakumbi xa ihlala ixesha elide – i-asidi kunye nokugqwala kwe-alkali? Akukho ngxaki! Amaqondo obushushu angama-800°C? Ikwanjalo! Iingxaki zokugqwala kunye nokukrwada kwee-brake pads zemveli zisonjululwa ngokulula ngefomula ye-ceramic ephuculweyo ye-nano-alumina.
II. “Indlu yoBusi” yokuCoca iGesi yoMphunga
Kwifektri ye-catalyst yaseBeijing, abasebenzi bafaka i-slurry ekhrimu kwisitya se-ceramic esimile okwe-honeycomb. Ingundoqo yale slurry yi-gamma-phase. i-nano-alumina, enommandla womphezulu we-130-200 m²/g. Oku kuthetha ukuba igram enye yale nto, esasazeke ngaphezu kwesiqingatha sobukhulu benkundla yebhasikithi, ilingana nobukhulu obuphindwe kathathu.
Xa umbane ophuma kwimoto udlula kwezi nano-coatings, iimolekyuli ze-carbon monoxide kunye ne-nitrogen oxide zifunxwa ngokuqinileyo kwiindawo ze-pore ze-alumina. Ii-catalysts zesinyithi ezixabisekileyo emva koko zithatha inyathelo, ziguqula zibe ziigesi ezingenabungozi. Ingcali kwiJingcheng New Materials isebenzise umzekelo: “I-Alumina ifana ne-scaffolding yesakhiwo, ivumela iplatinum kunye ne-palladium, 'ii-VIP', ukuba zihlale ziqinile kwaye zisebenze nzima!”
Uvavanyo lubonise ukuba ii-catalysts zisebenzisa i-10-30nmi-alumina yonyusa umsebenzi wobushushu obuphantsi phantse ngama-20%—oko kuthetha ukucocwa ngokukhawuleza komoya ophumayo kwanaxa kuqala ukubanda, oku kubalulekile ekuhlangabezaneni nemigangatho eqinileyo yokukhutshwa komoya eTshayina iVIb.
III. "Iphetshi Yokupholisa" yeePakethi zeBhetri
Yintoni abayoyika kakhulu abanini bezithuthi zamandla amatsha? Ubushushu obugqithisileyo bebhetri! Injineli eHangzhou Jiupeng New Materials ibonise ityhubhu yejeli eqhuba ubushushu efana ne-toothpaste: “Uyayibona loo mbala wesilivere? Ama-60% ayo yi-alumina engqukuva!” I-CY-L15S alumina thermal conductive powder isebenza njenge-“cooling patch” yeseli yebhetri.
Igrisi ye-silicone yendabuko inombane wobushushu we-1.5W/mK kuphela, ngelixa ijeli egcwele i-alumina inokufikelela ngaphezulu kwe-6W/mK. Uvavanyo kwiphakheji yebhetri evela kwi-CATL lubonise ukuba ukongeza umaleko wombane wobushushu we-alumina kunciphisa umahluko wobushushu kwiiseli zebhetri ngexesha lokutshaja ngokukhawuleza ukusuka kwi-15°C ukuya ngaphakathi kwe-5°C—okukhona umahluko wobushushu umncinci, kokukhona ubomi bebhetri bude.
Isicwangciso sokwandisa seTianma New Materials siqinisekisa ngakumbi imfuno ekhulayo: iprojekthi yokuvelisa iitoni ezingama-5,000 zepowder ye-alumina eqhuba ubushushu obuphezulu ngonyaka iqalile, ijolise kwimarike yokupholisa yeenkqubo ezintathu zombane zezithuthi ezintsha zamandla.
IV. "Indoda Yokuqinisa" Elula
"Ukunciphisa ubunzima ngaphandle kokulahla amandla" yeyona nto ibalulekileyo kwizithuthi ezikhaphukhaphu. Kwigumbi lesampulu leShanghai Gaoquan Chemical, i-alumina micropowder ye-α-phase alumina engama-80-160 gauge ifakwa kwi-epoxy resin: "Ukuyongeza kunokunciphisa ubukhulu bodonga lwe-bumper bracket nge-0.5mm, ngelixa kwandisa amandla ayo!"
Lo mgaqo ufana nekhonkrithi eqinisiweyo:amasuntswana e-aluminayenza “i-micro-skeleton” ngaphakathi kweplastiki. Idatha evela kumenzi wemoto othile ibonisa ukuba ukongeza i-30% ye-alumina kwizinto ze-polyamide ngaphakathi kwe-hood yenjini kunyusa ubushushu bokuguqulwa kobushushu ukusuka kwi-160°C ukuya kwi-290°C—indlela yokusindisa ubomi kwiindawo ezikufutshane ne-turbocharger.
Ixabiso lingcono nangakumbi: ukuqinisa ifayibha yekhabhoni kubiza njengegolide, ngelixa izinto ezidityanisiweyo ze-alumina zibiza isithathu kuphela.
V. Iplagi yeSpark “Isixhobo sokuKhusela”
Nqamla iplagi ye-spark yenjini uze ubone ukukhanya okukhazimlayo kwe-alumina micropowder yobushushu obuphezulu kwi-insulator yeseramik. Ingxelo yovavanyo evela kwiShanghai Gaoquan Chemical Industry ibonisa ukuba umzimba weseramik, owenziwe yi-96% α-phase alumina, unokumelana nokuqhuma ngequbuliso kwi-1700°C.
“Besisebenzisa izinto zodongwe eziqhelekileyo, kwaye beziqhekeka zize zivuze emva kweekhilomitha ezingama-80,000.” Injineli eyintloko yefektri ye-spark plug yabamba i-spark plug entsha.i-alumina ceramic umzimba waza wathi, “Ngoku, emva kweekhilomitha ezili-150,000, nokuba ii-electrode ziyatsha, i-ceramic ihlala injalo!” Oku kungenxa yophawu “lokuqina” lwe-alumina—ayirhubuluzi kumaqondo obushushu aphezulu kwaye inomlinganiselo wokwanda kobushushu ophantsi, nto leyo eyenza ibe sisiseko esiqinileyo ngaphakathi “kweNtaba evuthayo” yesilinda.
VI. "I-Ace Entsha" yeMfazwe Yexesha Elizayo
Uyilo lwe-alumina luyaqhubeka ngaphandle kokuphazamiseka. I-alumina engaqhelekanga eguqulwe umhlaba sele ibonakalise uphawu lwayo kwilebhu: ii-brake pads ezine-trace amounts ye-yttrium oxide ziphucula ukumelana nokuguguleka nge-10%, ngelixa i-catalyst coatings ephuculwe yi-cerium oxide yandisa ubomi bayo nge-30%.
Ezinye izicelo ezisemgangathweni zifumaneka ekuqhubeni ngobuchule—iilensi zeradar ze-millimeter-wave zifuna izinto ezithumela amaza kunye nezisusa ubushushu. Inkampani yaseHangzhou ivavanya izinto ezidityanisiweyo ze-alumina/silicone: i-dielectric constant yayo ihlala izinzile kwi-3.2, kwaye i-thermal conductivity yayo iphindwe kahlanu kuneplastiki yendabuko, nto leyo evumela i-radar ukuba "ibone" ngokuchanekileyo indlela nokuba kumaqondo obushushu ayi-120°C.
Ukususela kwizithuthi zepetroli zemveli ukuya kwiimoto ezikrelekrele zombane, uthotho lwexabiso lweumgubo we-aluminaiyaqhubeka nokwanda. Isenokungaze ivele kwiincwadana zezithuthi, kodwa xa sibamba ivili lokuqhuba, ibhuleki nganye ekhuselekileyo, ukukhutshwa kombane okusebenzayo, kunye nokukhupha umoya okucocekileyo kukhuselwa buthule yile mpuphu emhlophe, efihliweyo emehlweni.
Kwaye ngokuvela kweendawo ezintsha zemfazwe ezifana nee-solid-state battery thermal insulation pads kunye nee-hydrogen fuel cell stack guide plates, indlela ye-alumina yokuba "yintshatsheli efihliweyo" iyaqhubeka nokukhula.
