Ubwoko butandatu bwibisanzwe bikoreshwa nubushyuhe bwa nanomateriali

1. Nano diomand

Diamond ni ibikoresho bifite ubushyuhe bwo hejuru cyane muri kamere, hamwe nubushyuhe bwumuriro bugera kuri 2000 W / (mK) mubushyuhe bwicyumba, coefficente yo kwagura ubushyuhe bwa hafi (0.86 ± 0.1) * 10-5 / K, hamwe nubwishingizi mubyumba ubushyuhe. Mubyongeyeho, diyama ifite kandi imashini nziza, acoustique, optique, amashanyarazi na chimique, ibyo bigatuma igira inyungu zigaragara mugukwirakwiza ubushyuhe bwibikoresho bifotora amashanyarazi menshi, ibyo bikaba byerekana kandi ko diyama ifite imbaraga nyinshi zo gukoresha mumashanyarazi.
2. BN

Imiterere ya kirisiti ya hexahedral boron nitride isa niy'imiterere ya grafite.Ni ifu yera irangwa no kurekura, gusiga amavuta, kwinjizwa byoroshye nuburemere bworoshye.Ubucucike bwa teoretiki ni 2,29g / cm3, ubukana bwa mohs ni 2, kandi imiti ya chimique irahagaze neza cyane.Ibicuruzwa bifite ubukana bwinshi kandi birashobora gukoreshwa muri azote cyangwa argon ku bushyuhe bugera kuri 2800 ℃ .Ntabwo ifite coefficente yo kwagura ubushyuhe buke gusa, ahubwo ifite nubushyuhe bwo hejuru bwumuriro, ntabwo ari umuyoboro mwiza wubushyuhe gusa, ahubwo nubushakashatsi bwamashanyarazi busanzwe.Ubushyuhe bwa BN bwari 730w / mk kuri 300K.

3. SIC

Imiti yimiti ya karubide ya silicon irahagaze, kandi nubushyuhe bwayo bwumuriro nibyiza kuruta ibindi byuzuza igice cya kabiri, kandi nubushyuhe bwumuriro burenze icyuma mubushyuhe bwicyumba. Abashakashatsi bo muri kaminuza ya Beijing y’ikoranabuhanga ry’ubushakashatsi bakoze ubushakashatsi ku mashanyarazi ya alumina na karubide ya silicon. reberi ya silicone ishimangiwe.Ibisubizo byerekana ko ubushyuhe bwumuriro wa silicone reberi yiyongera hamwe no kwiyongera kwa karbide ya silikoni. Hamwe na karubide ya silikoni ingana, ubwinshi bwumuriro wa silicon reberi ishimangirwa nubunini buke burenze ubunini buke buke .

4. ALN

Nitride ya aluminium ni kirisiti ya atome kandi irashobora kubaho neza ku bushyuhe bwo hejuru bwa 2200 ℃.Hamwe nubushuhe bwiza bwumuriro hamwe na coefficente ntoya yo kwagura ubushyuhe, nibikoresho byiza birwanya ubushyuhe.Ubushyuhe bwumuriro wa nitride ya aluminium ni 320 W · (m · K) -1, yegereye ubushyuhe bwumuriro wa oxyde ya boron na silicon karbide ninshuro zirenga 5 za alumina.
Icyerekezo cyo gusaba: sisitemu yubushyuhe bwa silika gel, sisitemu ya plastike yubushyuhe, sisitemu ya epoxy resin sisitemu, ibicuruzwa byubutaka bwa ceramic.

5. AL2O3

Alumina ni ubwoko bwimikorere myinshi ya organic organique, hamwe nubushyuhe bunini bwumuriro, dielectric ihora kandi irwanya kwambara neza, ikoreshwa cyane mubikoresho bya reberi, nka silika gel, inkono ya kashe, epoxy resin, plastike, amashanyarazi yumuriro, plastike yubushyuhe bwumuriro , amavuta ya silicone, ceramics yubushyuhe nibindi bikoresho.Mu bikorwa bifatika, uwuzuza Al2O3 arashobora gukoreshwa wenyine cyangwa akavangwa nibindi byuzuza nka AIN, BN, nibindi.

6.Carbon Nanotubes

Amashanyarazi ya carbone nanotubes ni 3000 W · (m · K) -1, inshuro 5 zumuringa. Nanotubes ya karubone irashobora kuzamura cyane ubushyuhe bwumuriro, ubwikorezi nibintu bifatika bya reberi, kandi imbaraga zayo hamwe nubushyuhe bwumuriro nibyiza kuruta gakondo ibyuzuza nka karubone umukara, fibre fibre na fibre fibre.
