Thermal conductivity kua silicone roj hmab
Cov kua roj hmab silicone siv qee qhov qis-viscosity polysiloxane ua lub hauv paus polymer, reacts nrog cross-linking agents thiab catalysts, tuaj yeem sib txuas thiab kho ntawm chav tsev kub. Thermal conductivity kua silicone roj hmab (ob lub ntsiab lus) ntau lawm raws li txoj cai no. Lub thermal conductivity ob chav chav kub vulcanized silicone roj hmab tuaj yeem siv rau hauv cov khoom siv hluav taws xob, khoom siv hauv tsev, cov khoom ua si hluav taws xob, thiab lwm yam. Automotive qhov chaw thiab lwm yam khoom siv hluav taws xob, xws li hluav taws xob potting nplaum, rwb thaiv tsev nplaum nplaum, thermal conductivity thiab bonding adhesive. Nrog rau kev vam meej ntawm tib neeg, kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, thiab kev hloov tshiab thiab iteration ntawm cov khoom siv hluav taws xob, cov khoom siv ntawm cov kua silicone roj hmab no kuj tau nthuav dav, tsim cov lag luam muaj txiaj ntsig.
Kev piav qhia ntau lawm
Kev lag luam muaj thermal conductivity kua silicone roj hmab feem ntau ntim raws li ob lub ntsiab lus, thiab tseem muaj cov khoom ntim ib leeg, tab sis tus nqi yuav nce ntxiv. Thaum siv, ob yam khoom ntawm silicone roj hmab yog sib tov sib xyaw thiab nchuav rau hauv cov khoom siv hluav taws xob los ntawm cov cuab yeej, uas tuaj yeem kho tau los tsim cov txheej txheem tiv thaiv ntawm chav tsev kub.
Kev sib xyaw ntawm ob lub ntsiab lus no yog raws li hauv qab no

Chav tsev kub / kub curing silicone thermal conductivity khoom ua los ntawm cov saum toj no A thiab B Cheebtsam, no ob-tivthaiv elastic silicone yog tsim los rau pooping, tiv thaiv hluav taws xob khoom nyob rau hauv hnyav tej yam kev mob, xws li lub zog tshiab roj teeb, inverters, hluav taws xob modules los yog hluav taws xob khoom siv hluav taws xob. . Thaum ob qho khoom sib xyaw ua ke hauv ib qho kev faib ua feem, qhov sib tov yuav kho rau hauv elastomer. Cov colloid kho tau zoo heev lub cev thiab hluav taws xob.
Ntau lawm nta
1. Tsawg viscosity thiab zoo fluidity
2.High thermal conductivity thiab zoo heev tshav kub dissipation
3.Flame retardant, UL94V -0 nplaim qib
4.Nyob ruaj khov lub cev thiab txhua yam khoom ntawm -50 mus rau 200 degree nyob rau hauv lub sij hawm ntev
Thermal conductivity muab tub lim
Lub thermal conductivity ntawm silicone roj hmab yog nyob ntawm kev sib koom ua ke ntawm silicone roj hmab thiab thermal conductive muab tub lim, silicone roj hmab uas muaj ntau ntawm thermal conductive muab tub lim (xws li SiO2, Al2O3, BN), nws thermal conductivity yuav nce. Thaum tus nqi ntawm thermal conductivity muab tub lim me me, cov thermal conductivity ntawm cov khoom tsis zoo tuaj. Thaum tus nqi ntawm cov muab tub lim yog nce mus rau ib qho twg, kev sib cuag thiab kev sib cuam tshuam ntawm cov muab tub lim raug tsim, thiab cov thermal conductivity ntawm cov khoom tau zoo dua.
