... Thermal Conductive - Guangzhou Hongwu Material Technology Co., Ltd.

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, kupisa kwekuwedzera kwehumwe hunosvika (0.86±0.1)*10-5/K, uye kuvharisa mukamuri. Tembiricha.Kuwedzera, dhaimondi inewo yakanakisa mechanical, acoustic, optical, magetsi uye makemikari ehupfumi, izvo zvinoita kuti ive nemabhenefiti ari pachena mukupisa kupisa kwemhando yepamusoro-simba mafotoelectric zvishandiso, izvo zvinoratidzawo kuti dhaimondi rine hukuru hwekushandisa mundima yekupisa kupisa.
2. BN

Iyo crystal chimiro chehexahedral boron nitride yakafanana neyeiyo yegraphite layer structure.Ihupfu chena hunoonekwa nekusununguka, mafuta, kunyura nyore uye kureruka kurema.Theoretical density is 2.29g/cm3, mohs hardness is 2, uye makemikari emakemikari akanyanya kugadzikana.Chigadzirwa chacho chine hunyoro hwepamusoro uye hunogona kushandiswa munitrogen kana argon pamatembiricha kusvika ku2800 ℃.Haisi chete ine yakaderera thermal kuwedzera coefficient, asiwo ine high thermal conductivity, haisi chete conductor yakanaka yekupisa, asi inowanzoitika insulator yemagetsi.Thermal conductivity yeBN yaiva 730w / mk. ku300k.

3. SIC

Kemikari yesilicon carbide yakagadzikana, uye kupisa kwayo kuri nani kudarika mamwe semiconductor fillers, uye kupisa kwayo kunopisa kwakatokura kudarika simbi patembiricha yekamuri. 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 huduku hunokura 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, iyo 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 plastic. , silicone girisi, kupisa kupisa ceramics uye zvimwe zvinhu.Mukuita application, Al2O3 filler inogona kushandiswa yega kana kusanganiswa nemamwe mafirita akadai seAIN, BN, nezvimwe.

6.Carbon Nanotubes

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 kwemhepo zviri nani pane zvechinyakare. mafirita akadai sekabhoni dema, kabhoni fiber uye girazi fiber.
