Cov kauj ruam ntawm Kev Siv Hydrothermal Autoclaves
Nkag siab txog kev siv kom raug ahydrothermal autoclaveyog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig xav tau thiab ua kom muaj kev nyab xeeb. Nov yog cov lus qhia ib kauj ruam dhau los rau kev khiav hauj lwm cov cuab yeej muaj zog no:
Kev npaj: Pib los ntawm kev ua tib zoo xaiv koj cov reactants thiab xam cov ntim ntim uas tsim nyog. Nws yog ib qho tseem ceeb kom tsis txhob overfill lub autoclave, vim qhov no tuaj yeem ua rau muaj kev phom sij txaus ntshai.
Chaw thau khoom: Muab koj cov reactants tso rau hauv Teflon liner lossis cov tshuaj tiv thaiv chamber. Xyuas kom meej tias tag nrho cov ntsaws ruaj ruaj thiab gaskets huv si thiab nyob rau hauv qhov zoo ua ntej kev ruaj ntseg liner nyob rau hauv lub stainless hlau tsho.
Kev sib khi: Kaw lub autoclave kom ruaj ntseg, ua raws li cov chaw tsim khoom cov lus qhia. Rau cov ntsia hlau-hom ntsaws ruaj ruaj, siv lub xauv pas nrig kom nruj lub hau clockwise. Flange-type seals yuav xav tau txawm tias nruj ntawm ntau lub bolts.
Cua sov: Muab cov autoclave kaw rau hauv lub qhov cub lossis qhov cub. Maj mam nce qhov kub ntawm tus nqi ntawm 5 degree ib feeb kom txog thaum koj ncav cuag qhov ntsuas kub xav tau. Qhov kev nyab xeeb ua haujlwm kub rau Teflon-lined autoclaves feem ntau yog nyob ib puag ncig 200 degree, thaum PPL-lined versions tuaj yeem tiv taus kub txog 260 degree.
Lub Sijhawm Tawm Tsam: Khaws lub hom phiaj kub rau lub sij hawm cov tshuaj tiv thaiv predetermined. Qhov no tuaj yeem nyob ntawm ob peb teev mus rau ob peb hnub, nyob ntawm cov txheej txheem tshwj xeeb.
Txias: Tom qab cov tshuaj tiv thaiv tiav, cia lub autoclave txias ib txwm nyob ntawm tus nqi ntawm 5 degree ib feeb. Kev txias nrawm tuaj yeem ua rau thermal shock thiab ua rau cov khoom puas.
Kev nyuaj siab: Thaum txias rau hauv chav tsev kub, ua tib zoo qhib lub autoclave kom tso tawm cov kev ua haujlwm siab. Ib txwm ua raws li cov txheej txheem kev nyab xeeb thaum lub sijhawm cov kauj ruam no, vim tias qhov seem seem tuaj yeem ua rau muaj kev phom sij.
Cov khoom rov qab: Qhib lub liner thiab khaws koj cov khoom siv tshuaj tiv thaiv. Ntxuav lub liner kom huv si los npaj nws rau kev siv tom ntej.
Los ntawm kev ua raws li cov kauj ruam no, cov kws tshawb fawb thiab cov kws tshaj lij tuaj yeem siv lub zog ntawm hydrothermal synthesis los tsim ntau yam khoom siv nrog cov khoom tshwj xeeb.
