1. Ziziphi iimpawu ze-thermal silica gel (i-thermal potting glue)?
abicah conductive thermally ikwabizwa ngokuba thermally conductive potting glue okanye thermally conductive RTV glue.I-low-viscosity i-low-viscosity-retardant-two-component Ukongeza uhlobo lwe-silicone eqhuba ukushisa kwe-potting glue.Inokunyangwa kwiqondo lokushisa okanye ukufudumeza.Okukhona ubushushu buphezulu, kokukhona unyango olukhawulezayo.okukhethekileyo.Umahluko omkhulu kwigrisi ye-silicone ye-thermal kukuba i-silicone ye-thermal inokunyangwa kwaye ineempawu ezithile zokubambelela.
Ijeli ye-silica ye-Thermally conductive (iglue ye-thermally conductive potting) luhlobo lwerabha ye-silicone, eyerubha elulwelo lwe-vulcanization yecandelo elinye lobushushu.Emva kokuba ibonakaliswe emoyeni, i-silane monomers kuyo idibanisa ukwenza isakhiwo sothungelwano, inkqubo idibene, ayikwazi ukunyibilika kwaye inyibilike, i-elastic, ibe yi-rubbery, kwaye ibambelele kwizinto ngexesha elifanayo.I-thermal conductivity yayo iphezulu kancinane kunerabha eqhelekileyo, kodwa iphantsi kakhulu kunegrisi ye-silicone ye-thermal conductive, kwaye xa sele iphilisiwe, kunzima ukwahlula izinto eziboshiweyo.
2. Ziziphi iimpawu zegrisi ye-thermal
Igrisi ye-silicone ye-thermal conductive idla ngokubizwa ngokuba "yi-thermally conductive paste", "i-silicon intlama", igrisi ye-silicone conductive luhlobo oluphezulu lwe-thermal conductivity yokukhusela imathiriyeli ye-silicone, ayinyangi, kwaye inokugcina imeko yegrisi ixesha elide. kwiqondo lobushushu -50 ° C-+230 ° C izinto eziphathekayo conductive thermally.Ayinayo nje i-insulation egqwesileyo yombane, kodwa ine-conductivity egqwesileyo ye-thermal, kwaye kwangaxeshanye inokwahlukana kwe-oyile ephantsi (idla ngo-zero), ukuxhathisa ubushushu obuphezulu naphantsi, ukumelana namanzi, ukuxhathisa kwe-ozone, kunye nokumelana nokuguga kwemozulu.
Ingasetyenziswa ngokubanzi kwiimveliso ezahlukeneyo ze-elektroniki, kunye nomphezulu woqhagamshelwano phakathi kwezinto zokufudumeza (iityhubhu zamandla, ii-silicone ezilawulwayo ezihlaziyiweyo, izigxobo zokufudumeza zombane, njl. njl.) , ubungqina bokuthuthumela kunye nezinye iimpawu.
Ilungele ukugqunywa komphezulu okanye ukusetyenzwa kwezixhobo ezohlukeneyo zemayikhroweyivu ezinje ngonxibelelwano lwemicrowave, izixhobo zokuhambisa iimayikhroweyivu, ubonelelo lombane olukhethekileyo lwemayikhroweyivu, kunye nobonelelo lwamandla ombane oluzinzisiweyo.Olu hlobo lwezinto ze-silicon zibonelela nge-thermal conductivity egqwesileyo kumacandelo e-elektroniki avelisa ubushushu.Ezinjena: iitransistors, i-CPU assembly, thermistors, sensors sensors, i-automotive components electronic, iifriji zemoto, iimodyuli zamandla, iintloko zeprinta, njl.
3. Ukufana kunye nomahluko phakathi kwejeli ye-silika ye-thermal kunye ne-thermal grease
Yintoni abafana ngayo: bonke bane-conductivity ye-thermal kunye ne-insulation, kwaye zonke zizinto ze-interface ye-thermal.
umehluko:
I-silicone ye-thermally conductive (iglue yokufaka i-thermally conductive): incangathi (yakube ibambekile, kunzima ukuyisusa,
Ngoko ke, isetyenziswa kakhulu kwiimeko apho kufuneka ukuba kubekho ukudibanisa ixesha elinye kuphela.I-translucent, inyibilika kwiqondo lokushisa eliphezulu (i-viscous liquid), iqina (ibonakaliswe) kwiqondo lokushisa eliphantsi, ayikwazi ukunyibilika kunye nokuchithwa, kwaye i-elastic.
Igrisi ye-silicone ye-Thermally conductive (i-thermally conductive paste): I-Adsorptive, i-non-stick, incamathelisa i-semi-liquid, engaguqukiyo, ayinyangi (ayijiki kwiqondo lobushushu eliphantsi, kwaye ayibi ncinane kwiqondo lokushisa eliphezulu).
4. Umda wesicelo
Xa kuthelekiswa nejeli ye-silica, ukusetyenziswa kwegrisi ye-silicone kubanzi kakhulu.Iimveliso ezininzi zamashishini kunye ne-elektroniki zisebenzisa igrisi ye-silicone ye-thermal conductive apho kufuneka ukutshatyalaliswa kobushushu.
Ngaphezu koko, zininzi iintlobo zegrisi ye-silicone, kwaye abantu bongeza "ukungcola" kwigrisi ye-silicone ecocekileyo ye-thermal conductive ukuze kuphuculwe ukuhanjiswa kwayo kwe-thermal.
Obu bumdaka ngumgubo wegraphite, umgubo wealuminium, umgubo wobhedu njalo njalo.
Igrisi ye-silicone esulungekileyo imhlophe yobisi, igrisi yesilicone exutywe negraphite imnyama ngombala, igrisi yesilicone exutywe nomgubo we-aluminiyam ingwevu kwaye iyamenyezela, kwaye igrisi yesilicone exutywe nomgubo wobhedu inobutyheli noko.
