Peb txhua tus paub tias sab hauv lub tshuab hluav taws xob cua sov yuav tsum tau muaj cov hmoov av qhuav magnesium oxide hmoov thiab lwm cov chaw ntim, cov ntawv sau no muaj qee yam khoom hygroscopic.Qhov sau cov khoom siv sab hauv lub qhov cub hluav taws xob cua sov lub raj yuav muaj cov npoo kev ua haujlwm, cov cua kub tsis sib xws, thiab txawm tias qhov tshwm sim ntawm raj tawg.Yog li ntawd, txhawm rau kom zam cov khoom ntawm cov hluav taws xob cua kub yeeb nkab raug cuam tshuam los ntawm kev ya raws, peb yuav muab lub qhov chaw nres nkoj ntawm hluav taws xob cua kub yeeb nkab thaum peb tsim cov hluav taws xob cua kub yeeb nkab.Yog li cov khoom sib khi ntawm hluav taws xob cua sov raj ua lub luag haujlwm tseem ceeb heev.Yog li cas cov yam ntxwv ntawm hluav taws xob cua kub yeeb nkab sib khi cov ntaub ntawv?
1, cov khoom nws tus kheej muaj qhov siab ua tau zoo ntawm rwb thaiv tsev thiab hluav taws xob muaj zog.
2, cov khoom siv dag zog yog qhov dav, tus nqi yog tsawg.
3. Nws muaj qhov zoo sib xws thermal expansion coefficient nrog conductive txhuas pas nrig thiab hlau tsis muaj hlau ruaj khov.
4, muaj qhov ua tau zoo sealing ntawm cov dej nrawm thiab huab cua nruj, qhov kev ua tau zoo no yog qhov zoo tshaj plaws elastic foob.
5, nws qis hygroscopicity.
6, ntawm lub ntsuas kub ua haujlwm, kev ua haujlwm ntev yog tsis laus.
7. Muaj kub ua hauj.
8, cov txheej txheem no yooj yim, yooj yim rau kev khiav lag luam, tuaj yeem tsim rau huab hwm coj los yog tsim ntau lawm.
