Kev tsim cov qhov chaw evaporation thiab kev siv qhov teeb meem

Thaum lub tshuab nqus tsev vacuum thiab nqus tsev ion, cov khoom siv membrane yuav nyob rau hauv 1000 ~ 2000C kub siab, yog li ntawd nws Yanfa vaporization ntawm lub cuab yeej, hu ua qhov chaw evaporation. Evaporation qhov chaw ntau hom, qej plaub hau qhov chaw vaporization ntawm cov ntaub ntawv membrane yog cov hauv paus ntsiab lus sib txawv. Txawm li cas los xij, hais txog nws cov yam ntxwv ntawm daim ntawv thov, hauv kev tsim lossis daim ntawv thov, qhov tseem ceeb yuav tsum tau muab rau cov hauv qab no:

① qhov chaw evaporation yuav tsum ua tau raws li cov khoom siv membrane evaporation nrog tus nqi evaporation loj, thiab tuaj yeem khaws cia cov khoom siv membrane txaus;

② Qhov chaw ua kom cov dej noo tawm yuav tsum muaj lub neej ua haujlwm zoo dua thiab ntev dua;

③ Qhov chaw ua kom yaj yuav tsum tau siv rau ntau yam kev ua kom yaj ntawm cov hlau lossis cov hlau sib xyaw (xws li Al, Ti, Fe. Co. Cr) nrog rau cov tshuaj sib xyaw (piv txwv li SiO, SiO2, Zns thiab lwm yam);

④ Qhov chaw ua pa yuav tsum siv zog ua kom yooj yim hauv cov qauv, yooj yim ua, yooj yim siv thiab tswj, thiab pheej yig rau kev khiav lag luam.
