Cas 24304-00-5 Nano Aluminum Nitride AlN pauka
Nā hiʻohiʻona o ka pauka AlN:
Loaʻa i ka pauka AlN ka maʻemaʻe kiʻekiʻe, ka hāʻawi ʻana i ka nui o nā ʻāpana liʻiliʻi, ʻoi aku ka nui o ka ʻili, ka haʻahaʻa haʻahaʻa haʻahaʻa a ʻoi aku ka maikaʻi o ka hana ʻana i nā waiwai hoʻoheheʻe ʻia.2. Aluminum nitride nano pauka i hoʻohana 'ia i ka composite, a he mea hoʻohālikelike maikaʻi me ka semiconductor silicon a me kona maikaʻi interface hoʻopono hoʻomaikaʻi i ka mechanical waiwai a me ka thermal conductivity o ka composite mea.
Hōʻike o ka pauka AlN:
| 'ikamu | Maemae | APS | kalakala | ʻAiʻi Nui | ʻAno Crystallographic | maʻiʻo oxygen | Hana hana | SSA |
| XL-AlN pauda | 99% | 50nm | Hinahina | 0.05g/cm3 | Hexagonal hale | 0.8% | Plasma CVD | 105m2/g |
Nā noi o ka pauka AlN:
AlN pauka hoʻohana 'ia e hoʻomaikaʻi i ka hana o ka epoxy resin I Aluminum nitride nanopowder a me ka epoxy resin nenoaiu, i ka wa a ka maʻiʻo o Aluminum nitride nanoparticle hiki i 1% ~ 5%, aniani-hoʻololi wela piʻi a me ka module o ka elasticity hiki i ka nui waiwai.ʻO ka hoʻohui ʻana o Aluminum nitride nanopowder i nā mea hoʻohui epoxy resin he ʻokoʻa loa ia mai ka hoʻohui ʻana o Aluminum nitirde micro grain i loko o ke ʻano.Hoʻohui pinepine ʻia ka pauka AlN ma ke ʻano he ʻano mea hoʻoikaika a hoʻolaha nui ʻia ma waena o nā kaulahao o nā mea polymer.No ka lawa ʻole o ka hoʻonohonoho ʻana ma ka ʻili a me ka nui o ka ʻili, hōʻike ka pauka AlN i ka hana ikaika loa.I kēia manawa, ua māhele ʻia ka ʻāpana o ka Aluminum nitride nanoparticles grains i ka spacing o ke kaulahao polymer.Ke hoʻohālikelike ʻia me ka alumini nitride micro grain, loaʻa i ka pauka AlN ka wai maikaʻi loa a hiki ke hoʻomaikaʻi nui i ka ikaika, tenacity a me ka tractility o ka resin epoxy.
Hoʻohana ʻia ka pauka AlN no ka mea hoʻokele wela
ʻO ka silica gel i hui pū ʻia me ka pauka AlN, nona ka conductivity thermal super, hāʻawi i ka conductivity thermal maikaʻi loa, insulation uila, ʻoi aku ka nui o ka mahana hana o ka insulation uila (-60 ℃ ~ -200 ℃), haʻahaʻa haʻahaʻa a me ka hana hana maikaʻi, a hiki ke ākea ākea. hoʻohana ʻia i ka mīkini hoʻoili wela o ka mea uila e hoʻomaikaʻi i ka hana pono, e like me ka CPU radiator filler, high-power audion, controllable Silicon components, diode, thermal transmission medium in the seam a pēlā aku.
Hiki i ka pauka AlN ke hoʻomaikaʻi nui i ka conductivity thermal o ka plastic.Ma ka hoʻohui ʻana i nā nanoparticles Aluminum nitride i ka plastic e like me ka māhele o 5% ~ 10% i ka nuipa, hiki iā mākou ke hoʻonui i ka conductivity thermal o ka plastic mai 0.3W / (mk) a i 0.5W / (mk), 16 mau manawa hou aku.Ke hoʻohālikelike ʻia me ka hoʻopiha ʻana i ka wela (alumina a i ʻole magnesia) i ka mākeke, hiki iā ia ke hoʻomaikaʻi i nā waiwai mechanical o nā huahana me ka liʻiliʻi.I kēia manawa, ua kūʻai aku nā mea hana pili i ka pauka AlN i ka nui a e hoʻokuʻu ʻia ke ʻano hou nano heat conduction plastic i ka mākeke.
Hana maikaʻi loa ka pauka AlN i loko o ka silicon dioxide a makemake e hoʻopuehu i ka lāʻau.Ma lalo o ka manaʻo o ka hana ʻole ʻana i ka hana mechanical o ka lāʻau, (ua hōʻike ʻia nā hoʻokolohua e hiki ke hoʻomaikaʻi i ka hana mechanical o ka rubber), hiki iā ia ke hoʻomaikaʻi nui i ka conductivity wela o ka lāʻau a ʻaʻole e hoʻohaʻahaʻa i ka viscosity e like me nā oxides i ka wā o ka hoʻohui ʻana. , a he mea liʻiliʻi wale nō ke koi ʻia.Ua hoʻohana nui ʻia i ka pūʻali koa, ka mokulele a me ka ʻenehana ʻike.
