Kev Paub Txog Lub Tshuab Nqus Tsev Txhuam Txheej Txheem
May 23, 2019| Pib kev paub ntawm kev nqus tsev evaporation txheej txheem
Lub ntsiab ntawm lub tshuab nqus tsev evaporation khoom siv yog raws li nram no:
(1) nqus chamber, uas muab cov khoom nqus tsev kawm ntawv kom tsim nyog rau evaporation thiab tiv thaiv cov khoom ntawm oxidised thaum lub sijhawm evaporation; (2) evaporating qhov chaw thiab cov cua kub cua txias, uas yog siv los muab cov khoom siv evaporating thiab cua sov rau lawv; (3) substrate rau cov khoom noj evaporating thiab tsim ib cov yeeb yaj kiab evaporating ntawm nws qhov chaw; (4) phaj luj puag, siv rau cua sov lauj phuam; (5) ntsuas qhov ntsuas kub yog ntsuas kub ntsuas kub thermocouple.
Lub tshuab nqus tsev evaporation no muaj cov txheej txheem hauv qab no. 1. Cov cua kub thiab cov txheej txheem evaporation, nrog rau hloov theem ntawm cov txheej txheem xa mus rau cov roj (theem, theem ua kua lossis roj theem). Thaum twg tus compound tau vaporized los ntawm txhua yam khoom sib txawv ntawm qhov txawv ntawm qhov txawv ntawm qhov txawv ntawm qhov kub thiab qhov txawv ntawm qhov sib txawv ntawm qhov siab, nws lub zog ua haujlwm nrog lwm tus, qee yam uas nkag mus rau qhov chaw evaporation li gaseous lossis vapor.2. Kev thauj cov kab mob vaporized los yog cov khoom xyaw ntawm cov hmoov evaporation thiab cov substrate. Cov naj npawb ntawm kev sib tsoo ntawm cov khoom no thiab cov roj seem ntawm cov pa seem hauv lub voj voog thaum lub davhlau ntawm qhov chaw nyob yog nyob ntawm cov sib tsoo ntawm cov pa roj carbon monoxide ntawm cov evaporated atoms, qhov nruab nrab ntawm txoj kab kev qaug zog, thiab qhov kev ncua deb ntawm cov evaporated qhov chaw thiab lub substrate. 3. Cov txheej txheem uas muaj cov kabmob ua paug lossis cov kabmob vaporulates raug tso rau hauv cov substrate, uas yog, txheej txheem ntawm cov dej khov no, kev tsim nucleation, kev loj hlob ntawm nuclear thiab tsim muaj cov yeeb yaj kiab nyias. Txij thaum cov tshuaj kub qis dua qis dua li ntawm qhov evaporation, qhov hloov theem ntawm cov phom plaub hau ncaj qha tshwm sim nyob rau hauv cov substrate ntom ntawm cov roj theem mus rau theem.
Nyob hauv tus txheej txheem ntawm lub tshuab nqus tsev, lub tshuab nqus tsev rau cov evaporation txheej muaj ib lub luag hauj lwm tseem ceeb, vim evaporation atoms lossis molecules yuav sib tsoo nrog coob tus huab cua molecules, cov pa phem ntawm txheej membrane, ua oxide los yog cov evaporation txawm yog oxidation hlawv , los yog vim muaj kev sib tsoo thaiv huab cua molecules, nyuaj tsim homogeneous nruam nyias zaj duab xis. Yog li nws tseem ceeb heev kom muaj lub nqus dej ruaj khov, thiab txoj kev ua evaporation kuj yog qhov kev voos xyom kom siab ntawm qhov khoom siv. Yog li koj kuj yuav tsum paub txog tej yam hais txog kev kub ntxhov siab kom nkag siab txog kev hloov evaporation.
