Mashandisirwo Akawanda eAlumina Powder muIndasitiri yeMota
Pinda mukati memota yemazuva ano uye uchawanaupfu hwealumina ichiita mabasa akawanda chinyararire, asi isingawanzoonekwa nevatengi. Nhasi, ngatisimudzei hood tione kuti iyi poda chena inobata sei zvakanyanya mukufamba kwe "muviri wese" wemotokari.
Ⅰ. "Mapfupa Akaoma" eMabhureki Pads
"Mabhureki asina simba here? Zvingangodaro kuti zvinhu zvekukweshana hazvina kuoma zvakakwana!" mumwe mushandi wepafekitori yemabhureki akachema-chema achiyedza mabhureki. Simba rayo rinoshamisa: kuwedzera 3%-5% chete pazvinhu zvekukweshana kunogona kuwedzera kuomarara kwepamusoro pebhureki. Zvakafanana nejira diki rezvombo, zvichidzivirira kuti risakanganise kana kuputsika kana paine kukweshana kwakanyanya. Data kubva kuHangzhou Jikang New Materials rinoratidza kuti kuwedzerwa kwechinhu ichi kunovandudza kusakara kwebhureki neanopfuura 15%, zvichiita kuti ive chishandiso chinochengetedza mari yetekisi ine kutanga nekumira kakawanda.
Zviri nani here kugara kwayo kwenguva refu - ngura ine acid nealkali? Hapana dambudziko! Tembiricha ye800°C? Kunyangwe zvakadaro! Matambudziko engura nekuchema kwemabrake pads esimbi echinyakare anogadziriswa zviri nyore ne nano-alumina-enhanced ceramic formula.
II. "Imba yeUchi" yekuchenesa Gasi Rinobuda Nemhepo
Pafekitori ye catalyst yeBeijing, vashandi vanoisa slurry ine kirimu pamuchina we ceramic wakaita seuchi. Chinhu chikuru cheslurry iyi i gamma-phase. nano-alumina, ine nzvimbo yepamusoro ye130-200 m²/g. Izvi zvinoreva kuti gramu imwe chete yechigadzirwa ichi, yakapararira kupfuura hafu yehukuru hwenhandare yebasketball, yakaenzana nehukuru hwakapetwa katatu.
Kana utsi hwemotokari huchipfuura nepakati pema nano-coatings aya, mamorekuru ecarbon monoxide ne nitrogen oxide anonamirwa zvakasimba pamusoro pemaburi ealumina. Zvinhu zvinokosha zvesimbi zvinotora matanho, zvichizvishandura kuita magasi asina njodzi. Nyanzvi yezvemagetsi kuJingcheng New Materials yakashandisa fananidzo: “Alumina yakafanana nescaffolding yechivako, zvichiita kuti platinum nepalladium, 'VIPs', zvigare zvakasimba uye zvishande nesimba!”
Ongororo dzakaratidza kuti ma catalysts anoshandisa 10-30nmalumina kuwedzera kushanda kwemhepo inopisa neanenge 20% - zvichireva kucheneswa kweutsi nekukurumidza kunyangwe panguva yekutonhora, zvakakosha kuti pave nekusangana nemitemo yakasimba yeChina VIb emission.
III. "Chigadziko Chekutonhodza" Chemapaketi Emabhatiri
Chii chinonyanya kutyiwa nevaridzi vemotokari itsva dzinoshandisa simba? Kupisa kwebhatiri! Mumwe mainjiniya wepaHangzhou Jiupeng New Materials akaratidza chubhu yegel inofambisa mafuta yakaita seyemazino: "Unoona kupenya kwesirivha here? 60% yayo idenderedzwa realumina!" Upfu hwealumina hunofambisa mafuta hweCY-L15S hunoshanda se "nzvimbo inotonhorera" yebhatiri.
Girisi rechinyakare resilicone rine simba rekupisa re1.5W/mK chete, nepo gel yakazadzwa nealumina ichigona kusvika pamusoro pe6W/mK. Miedzo yakaitwa pabhatiri kubva kuCATL yakaratidza kuti kuwedzera jira rekupisa realumina kwakaderedza musiyano wekupisa mumaseru ebhatiri panguva yekuchaja nekukurumidza kubva pa15°C kusvika mukati me5°C—musiyano wekupisa uri mudiki, ndiko kureba kwenguva yehupenyu hwebhatiri.
Hurongwa hwekuwedzera hweTianma New Materials hunosimbisawo kudiwa kuri kukura: chirongwa chekugadzira matani zviuru zvishanu eupfu hwealumina hunopisa zvakanyanya gore rega rega chakatanga, chakanangana nemusika wekutonhodza masisitimu matatu emagetsi emotokari itsva dzinoshandisa magetsi.
IV. "Murume Anosimbisa" Akareruka
"Kuderedza huremu pasina kurasikirwa nesimba" ndiyo kiyi yemotokari dzinorerutsa. Mukamuri remuenzaniso reShanghai Gaoquan Chemical, upfu hwealumina hwe α-phase 80-160 gauge hunosanganiswa mu epoxy resin: "Kuiwedzera kunogona kuderedza ukobvu hwemadziro ebhuraketi rebhampa ne 0.5mm, ukuwo uchiwedzera simba rayo!"
Nheyo yacho yakafanana nekongiri yakasimbiswa:zvidimbu zvealuminavanogadzira "skeleton diki" mukati mepurasitiki. Data kubva kune mumwe mugadziri wemotokari rinoratidza kuti kuwedzera 30% alumina kune polyamide material iri mukati meinjini hood kunowedzera tembiricha yekuchinja kwekupisa kubva pa160°C kusvika 290°C—inoponesa hupenyu hwezvinhu zviri pedyo neturbocharger.
Mari yacho iri nani kupfuura iyi: carbon fiber reinforcement inodhura segoridhe, nepo alumina composites ichidhura chikamu chimwe chete muzvitatu chete.
V. Chivharo cheSpark "Chidziviriro Chekudzivirira"
Bvisa chivharo cheinjini uye uchaona kupenya kweupfu hwe alumina micropowder hunodziya zvakanyanya pa ceramic insulator. Mushumo wekuyedza kubva kuShanghai Gaoquan Chemical Industry unoratidza kuti muviri we ceramic, unoumbwa ne 96% α-phase alumina, unogona kutsungirira kuputika kamwe kamwe pa 1700°C.
"Taishandisa zviumbwa zvesimbi zvakajairika, uye zvaitsemuka zvodonha mushure memakiromita 80,000." Mainjiniya mukuru wefekitori yespark plug akasimudza chivakwa chitsva.alumina zvedongo muviri ndokuti, “Zvino, mushure memakiromita 150,000, kunyangwe maerekitirodhi akatsva, ceramic inoramba yakadaro!” Izvi zvinokonzerwa nehunhu hwe "alumina" hwakasimba—haitsvedzerere pakupisa kwakanyanya uye ine thermal expansion coefficient yakaderera, zvichiita kuti ive hwaro hwakasimba mukati me "Flaming Mountain" yecylinder.
VI. "Ace Itsva" yeHondo Yemangwana
Kugadzira Alumina kuri kuramba kuchienderera mberi. Alumina isingawanzo shandiswa pasi yakatoonekwa murabhoritari: mabhureki ane huwandu hushoma hwe yttrium oxide anowedzera kuramba kweganda ne10%, nepo cerium oxide-enhanced catalyst coatings inowedzera hupenyu hwemuviri ne30%.
Mamwe mashandisirwo epamusoro ari mukutyaira kwakangwara—magirazi eradar ane mamirimita anoda zvinhu zvinotumira mafungu uye zvinobvisa kupisa. Kambani yeHangzhou iri kuyedza chinhu chakagadzirwa nealumina/silicone: chinhu chayo che dielectric chinoramba chakasimba pa3.2, uye thermal conductivity yayo yakapetwa kashanu pane yepurasitiki yechinyakare, zvichiita kuti radar ikwanise "kuona" mugwagwa nemazvo kunyangwe patembiricha ye120°C.
Kubva pamotokari dzemafuta dzechinyakare kusvika kumotokari dzemagetsi dzakangwara, cheni yekubatsira yeupfu hwealuminainoramba ichikura. Ingasamboonekwa mumabhurocha emotokari, asi patinobata chidhiraivho, mabhureki ese akachengeteka, kuburitswa kwese kwemagetsi kunobudirira, uye mweya wega wega wakachena unodzivirirwa chinyararire nehupfu huchena uhwu, hwakavanzwa kuti hauonekwe.
Uye nekubuda kwenzvimbo itsva dzehondo dzakadai sema "solid-state battery thermal insulation pads" uye ma "hydrogen fuel cell stack guide plates", nzira yealumina yekuva "mhare yakavanzwa" iri kuramba ichikura.
