Thaum tshav kub kub ua Epoxy
Heat Conducting Epoxy yog kev tshawb fawb txog kev tswj xyuas cov khoom siv thermal tsim los daws cov teeb meem tseem ceeb ntawm cov cua sov dissipation hauv cov khoom siv hluav taws xob niaj hnub thiab hluav taws xob. Qhov tshwj xeeb epoxy resin no tau txais kev hloov kho lub hom phiaj txhawm rau txhim kho nws cov thermal conductivity, hloov nws los ntawm cov txheej txheem insulator rau hauv cov cua kub zoo- hloov nruab nrab. Tus yuam sij rau nws qhov kev ua tau zoo yog nyob rau hauv kev sib koom ua ke ntawm siab -purity thermally conductive fillers, xws li txhuas oxide thiab silicon micro- hmoov, rau hauv epoxy polymer matrix. Los ntawm kev tswj xyuas meej ntawm hom muab tub lim, particle loj faib, concentration, thiab interfacial bonding, peb formulation engineers tsim nruam thiab ua tau zoo thermal txoj hauv cov khoom. Qhov kev ua kom zoo no tso cai rau cov khoom lag luam kom ua tiav cov thermal conductivity ntau dua piv rau cov pa epoxy.
Tshaj li nws cov thermal ua haujlwm tseem ceeb, cov khoom siv no muaj peev xwm tswj tau cov txheej txheem ntawm cov khoom muaj txiaj ntsig cuam tshuam nrog hwm epoxy resins. Qhov tshwm sim Thaum tshav kub kub ua Epoxy nthuav tawm cov hluav taws xob zoo heev, ua kom muaj kev nyab xeeb thiab tiv thaiv luv luv. Nws muaj formidable mechanical zog rau cov qauv kev them nyiaj yug, siab tshuaj stability los tiv thaiv degradation, zoo heev adhesion rau ntau yam substrates, thiab cov yam ntxwv zoo rau kev yooj yim ntawm daim ntawv thov. Qhov kev sib xyaw tshwj xeeb ntawm thermal kev ua tau zoo thiab cov khoom siv ruaj khov ua rau cov khoom lag luam xaiv zoo rau cov ntawv thov nrog ntau yam kev xav tau. It is extensively utilized in power-dense electronic appliances, thermal management modules for new energy vehicle lithium-ion batteries, and various automotive electronics, particularly in assemblies where high heat flux, post-curing stability, electrical insulation, and resistance to moisture or corrosion are simultaneously required. Los ntawm kev xaiv Heat Conducting Epoxy, koj koom ua ke ib qho kev txhim khu kev qha thermal interface uas txhawb kev ua haujlwm ntev thiab kev nyab xeeb ntawm kev ua haujlwm.

Cov Txheej Txheem Nqus Tsev Casting System
Tom qab tag nrho cov casting lub cev tau sib sau ua ke thiab molded, thov tso tus neeg sawv cev rau pwm thiab muab lub cev casting rau hauv qhov cub ntawm 80-100℃rau 5-8 teev.
Siv cov khoom raws li B: A piv ntawm 1: 1 thiab muab tso rau hauv qhov cub kub tsis tu ncua. Preheat qhov cub kom 70℃ntawm chav tsev kub (25 degree) thiab tuav rau 2-3 teev.
Hloov lub cev qhuav qhuav mus rau lub tank casting. Teem lub tank kub rau 70-75 degree. Ib txhij, ntxiv cov khoom preheated rau lub tank casting, teem lub tank kub rau 60 degree.
Teem cov khoom kub hauv lub tank sib tov rau 60 degree. Do thiab tshem tawm lub tshuab nqus tsev mus rau 50-150Pa. Saib xyuas los ntawm cov iav pom tias cov khoom tau degassed ua ntej casting.
Nyob ntawm qhov loj ntawm lub cev casting, tswj lub sijhawm casting mus rau 30-70 feeb. Tom qab casting, tswj lub tshuab nqus tsev rau 30-40 feeb, tom qab ntawd tawg lub tshuab nqus tsev thiab siv 2 kg ntawm siab ua ntej tshem tawm lub cev casting ntawm lub tank.
