Cov cuab yeej ziab kom qhuav yuav ua li cas khiav haujlwm zoo

Abstracts:

Cov tshuab ziab khaub ncaws kuj tseem hu ua tshuab ziab khaub ncaws thiab tshuab ziab khaub ncaws. Lub hom phiaj ntawm kev ziab yog siv rau cov khoom siv los yog kev xav tau ntxiv. Xws li ntoo hauv kev tsim cov pwm pwm, ntoo ua ntej ziab tuaj yeem tiv thaiv cov khoom deformation, ceramic blanks hauv calcination ntawm ob lub tshuab ziab khaub ncaws ua ntej ziab tuaj yeem tiv thaiv cov khoom tiav tawg. Tsis tas li ntawd, cov khoom siv qhuav kuj yog ib qho yooj yim rau kev thauj thiab khaws cia, xws li cov qoob loo qhuav kom qhuav rau qee cov dej noo hauv qab no, txhawm rau tiv thaiv pwm thiab pwm. …

Cov tshuab ziab khaub ncaws kuj tseem hu ua tshuab ziab khaub ncaws thiab tshuab ziab khaub ncaws. Lub hom phiaj ntawm kev ziab yog siv rau cov khoom siv los yog kev xav tau ntxiv. Xws li ntoo hauv kev tsim cov pwm pwm, ntoo ua ntej ziab tuaj yeem tiv thaiv cov khoom deformation, ceramic blanks hauv calcination ntawm ob lub tshuab ziab khaub ncaws ua ntej ziab tuaj yeem tiv thaiv cov khoom tiav tawg. Tsis tas li ntawd, tom qab ziab cov khoom siv kuj yooj yim rau kev thauj mus los thiab khaws cia, xws li cov qoob loo ziab kom qhuav rau qee yam dej noo hauv qab no, txhawm rau tiv thaiv pwm thiab pwm. Raws li lub ntuj ziab kom deb ntawm qhov tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev tsim khoom, ntau hom tshuab ziab khaub ncaws yog siv ntau thiab ntau dua.

Cov txheej txheem ziab yuav tsum tau siv ntau lub zog thermal, thiaj li yuav txuag tau lub zog, qee cov ntaub ntawv uas muaj cov dej noo siab, muaj cov khib nyiab tshem tawm los yog kev daws teeb meem feem ntau yog ua ntej los ntawm kev siv lub cev qhuav dej lossis cua sov evaporation, thiab tom qab ntawd ziab hauv lub tshuab ziab khaub ncaws kom tau txais qhuav khoom.

Nyob rau hauv cov txheej txheem ziab yuav tsum tau ua kom tiav tib lub sij hawm hloov ntawm tshav kub thiab huab hwm coj (moisture), los xyuas kom meej tias ib nrab siab ntawm noo noo vapor (concentration) nyob rau saum npoo ntawm cov khoom yog siab tshaj ib nrab siab ntawm noo noo vapor nyob rau hauv. qhov chaw sab nraud, kom ntseeg tau tias qhov kub ntawm qhov cua sov yog siab dua qhov kub ntawm cov khoom.
Thaum tshav kub kub los ntawm qhov kub-kub kub qhov chaw nyob rau hauv ntau txoj kev mus rau cov khoom ntub dej, kom cov khoom nto ya raws vaporization thiab khiav mus rau qhov chaw sab nraud, kom cov khoom nto thiab cov khoom hauv cov dej noo sib txawv. Internal ya raws mus rau saum npoo ntawm diffusion thiab vaporization, thiaj li hais tias cov dej noo ntawm cov khoom txuas ntxiv txo, thiab maj mam ua kom qhuav ntawm cov khoom tag nrho.
