Yuav ua li cas xaiv cov degree ntawm lub tshuab nqus tsev hauv txoj kev ziab khaub ncaws hauv lub tshuab ziab khaub ncaws?
Yuav ua li cas xaiv cov degree ntawm lub tshuab nqus tsev hauv txoj kev ziab khaub ncaws hauv lub tshuab ziab khaub ncaws? Nws yog txheej txheem scientific los txiav txim siab tsim nyog kom khov rau khov kom qhuav los ntawm lub vapor siab ntawm dej khov. Ib qho kev ntsuas tseem ceeb rau kev xaiv qhov system siab: dej khov yog nyob rau thaj tsam ntawm 20% mus rau 30% ntawm vapour siab ntawm cov khoom lag luam kub. Sublimation tshwm sim thaum lub tshuab nqus qib teeb tsa taw tes qis dua lub vapour siab ntawm qhov dej khov yog ntawm cov khoom kub tam sim no.
Nquag, qhov khov-kom qhuav ntawm lub tshuab nqus tsev yog tswj tau los ntawm 50 thiab 300 mTorr (0.06 txog 0.40 mbar), thiab 100 rau 200 mTorr (0.13 txog 0.26 mbar) yog qhov ntau ntau.
Raws li tuaj yeem pom los ntawm cov lus hauv qab no, muaj qhov sib txuas ntawm qhov kub thiab txias. Qhov qis dua qhov kub ntawm dej khov, qhov qis dua ntawm lub vapor siab. Yog hais tias lub lyophilizer tsis tau tswj hwm tsis tu ncua mus rau lub tshuab nqus tsev qis, nws yuav tsis muaj qhov system system teeb tsa taw tes ntawm 20% mus rau 30% ntawm dej khov vapor siab ntawm cov khoom lag luam qis heev (hauv qab -40oC). nruab nrab ntawm. Yog li ntawd, khov qhuav yuav ua mus qeeb heev ntawm cov khoom lag luam qis heev.
