Lub uniformity ntawm foaming nyob rau hauv cov khoom siv roj hmab-yas tseem ceeb heev rau lawvthermal conductivity(qhov taw qhia tseem ceeb ntawm kev ua haujlwm rwb thaiv tsev), uas ncaj qha txiav txim siab qhov zoo thiab ruaj khov ntawm lawv cov rwb thaiv tsev. Cov kev cuam tshuam tshwj xeeb yog raws li hauv qab no:
1. Uniform Foaming: Ua kom muaj kev ua tau zoo ntawm rwb thaiv tsev
Thaum ua npuas ncauj yog sib txawv, me me, faib cov khoom faib, thiab cov npuas me me ntawm cov khoom sib thooj loj hauv cov khoom. Cov npuas no zoo thaiv kev hloov pauv cua sov:
- Cov huab cua ntws nyob rau hauv cov me me, nyob rau hauv npuas npuas yog tsis tshua muaj heev, txo convection tshav kub hloov.
- Cov qauv npuas tsis sib xws tiv thaiv kom tsis txhob muaj cua sov los ntawm kev nkag mus los ntawm cov ntsiab lus tsis muaj zog, ua kom muaj kev ruaj khov, ruaj khov thaiv thaiv.
Qhov no tuav cov thermal conductivity tsawg (feem ntau, cov thermal conductivity ntawm cov khoom siv roj hmab-yas rwb thaiv tsev tsim nyog yog ≤0.034 W / (m·K)), yog li ua tiav cov rwb thaiv tsev zoo.
2. Cov Foaming tsis sib xws: Txo qhov ua tau zoo ntawm rwb thaiv tsev
Kev ua npuas tsis sib xws (xws li kev hloov pauv loj hauv npuas loj, thaj chaw tsis muaj npuas, lossis tawg / sib txuas npuas) tuaj yeem ua rau cov qauv rwb thaiv tsev ncaj qha, ua rau txo cov rwb thaiv tsev. Cov teeb meem tshwj xeeb suav nrog:
- Thaj chaw ntom ntom hauv zos (Tsis muaj / Tsawg npuas): Qhov chaw ntom ntom tsis muaj npuas rwb thaiv tsev. Lub thermal conductivity ntawm cov roj hmab-yas matrix nws tus kheej yog siab dua li ntawm huab cua, tsim "kub raws" uas hloov cov cua sov sai sai thiab tsim "cov rwb thaiv tsev qhov chaw tuag."
- Cov npuas loj / txuas nrog: Cov npuas loj heev tuaj yeem ua rau tawg, lossis ntau cov npuas txuas mus rau hauv daim ntawv "air convection channels." Huab cua ntws hauv cov channel no ua rau cov cua sov pauv thiab ua kom cov thermal conductivity nce ntxiv.
- Zuag qhia tag nrho Performance Unstable: Txawm hais tias foaming tau txais nyob rau hauv qee qhov chaw, cov qauv tsis sib xws tuaj yeem ua rau muaj kev hloov pauv ntawm cov khoom siv rwb thaiv tsev tag nrho, ua rau nws tsis tuaj yeem ua tau raws li cov kev xav tau ntawm rwb thaiv tsev ruaj khov. Sij hawm dhau mus, cov qauv npuas tsis sib xws tuaj yeem ua rau muaj kev laus zuj zus ntxiv, ua rau muaj kev puas tsuaj ntxiv rau kev puas tsuaj.
Yog li ntawd,uniform foamingyog qhov tsim nyog ua ntej rau kev ua haujlwm thermal rwb thaiv tsev ntawm cov roj hmab thiab cov khoom yas. Tsuas yog nrog cov foaming tsis sib xws tuaj yeem ua kom ruaj khov npuas qauv ntxiab huab cua thiab thaiv kev hloov hluav taws xob. Txwv tsis pub, cov txheej txheem tsis xws luag yuav txo qhov thermal rwb thaiv tsev nyhuv.
Kingflex cov khoom siv cov txheej txheem ntau lawm los xyuas kom meej tias cov foaming zoo ib yam, uas ua rau muaj kev ua haujlwm zoo dua thermal rwb thaiv tsev.
