Mhando nhanhatu dzeanowanzo shandiswa thermal conductive nanomaterials
1. Nano diomand
Dhaimondi ndicho chinhu chine yakanyanya kupisa conductivity muchisikirwo, ine kupisa kwemhepo kunosvika 2000 W/(mK) patembiricha yekamuri, tembiricha yekuwedzera yekupisa inosvika (0.86± 0.1)*10-5/K, uye kuvharira mumba. Tembiricha.Kuwedzera, dhaimondi inewo yakanakisa mechanical, acoustic, optical, magetsi nemakemikari zvivakwa, izvo zvinoita kuti ive pachena zvakanakira mukupisa kupisa kwepamusoro-simba photoelectric zvishandiso, izvo zvinoratidzawo kuti dhaimondi rine hukuru hwekushandisa mundima yekupisa kupisa.
2. BN
Iyo crystal chimiro chehexahedral boron nitride yakafanana neyeiyo yegraphite layer structure.Ihwo hupfu chena hunoratidzwa nekusununguka, mafuta, kunyura nyore uye kureruka.Theoretical density is 2.29g/cm3, mohs hardness is 2, uye makemikari emakemikari akanyanya kugadzikana.Chigadzirwa chacho chine hunyoro hwepamusoro uye hunogona kushandiswa mu nitrogen kana argon pamatembiricha kusvika ku2800 ℃.Haisi chete ine yakaderera thermal kuwedzera coefficient, asiwo ine high thermal conductivity, haisi chete conductor yakanaka yekupisa, asi yakajairika magetsi insulator.Thermal conductivity yeBN yaiva 730w / mk. ku300k.
3. SIC
Kemikari pfuma yesilicon carbide yakagadzikana, uye kupisa kwayo kuri nani kupfuura mamwe semiconductor fillers, uye kupisa kwayo kunopisa kwakatokura kudarika simbi pane imwe imba tembiricha. reinforced silicone rubber.Zvigumisiro zvinoratidza kuti thermal conductivity yesilicone rubber inowedzera nekuwedzera kwehuwandu hwesilicon carbide.Nehuwandu hwakafanana hwesilicon carbide, thermal conductivity yesilicon rubber yakasimbiswa nehukuru diki yakakura kudarika guru guru. .
4. ALN
Aluminium nitride ikristaro yeatomu uye inogona kuvapo yakadzikama pakupisa kwepamusoro kwe2200 ℃.Nekunaka kwekupisa kwekushisa uye diki coefficient yekuwedzera kwekupisa, chinhu chakanaka chinodzivirira kupisa chinopisa zvinhu.Thermal conductivity yealuminium nitride ndeye 320 W· (m·K) -1, iri pedyo nekupisa kwekushisa kwe boron oxide uye. silicon carbide uye kanopfuura ka5 iyo yealumina.
Nzira yekushandisa: thermal silica gel system, thermal plastic system, thermal epoxy resin system, thermal ceramic products.
5. AL2O3
Alumina imhando yeakawanda-inoshanda inorganic filler, ine hombe yekupisa yekupisa, dielectric inogara uye nani kupfeka kuramba, inoshandiswa zvakanyanya murubber composite zvinhu, senge silica gel, potting sealant, epoxy resin, plastiki, rubber thermal conductivity, thermal conductivity plastiki. , silicone girisi, kupisa kupisa ceramics uye zvimwe zvinhu.Mukushanda kwekushandisa, Al2O3 filler inogona kushandiswa yega kana kusanganiswa nemamwe mafirita akadai seAIN, BN, nezvimwe.
6.Carbon Nanotubes
The thermal conductivity of carbon nanotubes is 3000 W· (m·K) -1, 5 times that of copper.Carbon nanotubes inogona kuvandudza zvakanyanya thermal conductivity, conductivity uye zvinhu zvemuviri zverabha, uye kusimbisa kwayo uye kupisa kwekushisa kuri nani kudarika tsika. mafirita akadai sekabhoni dema, kabhoni fiber uye girazi fiber.
