Qhov sib txawv tseem ceeb ntawm azeotropic thiab zeotropic sib tov yog qhov dej lwg thiab npuas taw tes ntawm qhov sib xyaw azeotropic sib tshuam whereas dew point thiab npuas taw tes ntawm zeotropic sib tov yog qhov txawv.
Cov ntsiab lus azeotropic thiab zeotropic sib xyaw muaj feem cuam tshuam rau ib leeg vim lawv muaj cov khoom sib txawv rau ib leeg. Yog li ntawd, lawv muaj qhov sib txawv dew thiab npuas nkhaus yam ntxwv zoo li. Cov dej lwg thiab npuas nkhaus no tau kos rau hauv cov duab ntsuas kub.
Azeotropic Mixture yog dab tsi?
Azeotropic sib tov yog cov tshuaj sib xyaw uas muaj cov kua dej uas muaj qhov kub tsis tu ncua. Qhov no yog vim lub vapor ntawm cov kua sib tov muaj tib yam li cov kua sib tov. Qhov kub ntawm qhov sib tov no tuaj yeem siab dua lossis qis dua ib qho ntawm cov khoom sib xyaw ntawm cov khoom sib xyaw.

Vim tias qhov kub ntawm qhov sib xyaw azeotropic yog qhov tas li, peb tsis tuaj yeem siv cov distillation yooj yim rau kev sib cais ntawm cov khoom hauv qhov sib tov. Yog li ntawd, peb yuav tsum tau siv lwm yam txuj ci xws li siv ob kab distillation nrog ntau qib ntawm kev sib cais los yog ntxiv ntawm ib tug thib peb compound rau azeotropic sib tov thiaj li yuav hloov lub volatility thiab boiling point ntawm lub Cheebtsam.
Zeotropic Mixture yog dab tsi?
Zootropic sib tov yog sib xyaw ntawm cov kua dej uas muaj cov ntsiab lus kub sib txawv. Txij li nws yog qhov sib txawv ntawm qhov sib xyaw azeotropic, peb tuaj yeem hu nws tsis yog azeotropic sib tov. Vim qhov sib txawv ntawm lawv cov ntsiab lus boiling, ib tug neeg cov khoom tsis raug evaporation los yog condensation ntawm tib qhov kub thiab txias. Yog li ntawd, qhov sib tov yog nyob rau hauv ib tug kub glide. Cov theem hloov pauv ntawm cov khoom ua kua ua rau muaj qhov kub thiab txias ntau dua li qhov kub thiab txias.

Yog tias peb kos qhov kub thiab qhov sib xyaw ua ke rau zeotropic sib tov, peb tuaj yeem soj ntsuam qhov kub kub ntawm cov khoom nruab nrab ntawm npuas taw tes thiab cov dej dew point. Lub npuas taw tes yog qhov kub ntawm qhov uas thawj npuas ntawm vapor cov ntaub ntawv. Dew point yog qhov kub ntawm qhov chaw condensation. Qhov ntsuas kub thiab qhov sib xyaw ua ke qhia pom tias muaj pes tsawg leeg ntawm cov kua thiab vapor hloov li cas thaum boiling, condensing thiab kub nyob nruab nrab ntawm lawv. Ib qho piv txwv ntawm zeotropic sib tov yog sib xyaw ntawm ethane, methane, nitrogen, propane thiab isobutene.
Qhov txawv ntawm Azeotropic thiab Zeotropic Mixture yog dab tsi?
Azeotropic thiab zeotropic yog cov lus sib txawv. Qhov sib txawv tseem ceeb ntawm azeotropic thiab zeotropic sib tov yog qhov dej lwg taw tes thiab npuas taw tes ntawm qhov sib xyaw azeotropic sib tshuam, whereas lub lwg taw tes thiab npuas taw tes ntawm zeotropic sib tov yog qhov txawv. Qhov ntawd txhais tau tias, peb tuaj yeem pom ob lub ntsiab lus raws li qhov taw tes npuas thiab dej lwg taw tes hauv daim duab ntawm qhov kub thiab txias ntawm cov khoom sib xyaw hauv zeotropic, tab sis rau qhov sib xyaw azeotropic, cov ntsiab lus no nyob ib leeg.
Ua raws li yog cov ntsiab lus ntawm qhov sib txawv ntawm azeotropic thiab zeotropic sib tov.
Summary – Azeotropic vs Zeotropic Mixture
Cov ntsiab lus azeotropic thiab zeotropic yog qhov sib txawv rau ib leeg. Qhov sib txawv tseem ceeb ntawm azeotropic thiab zeotropic sib tov yog qhov dej lwg taw tes thiab npuas taw tes ntawm qhov sib xyaw azeotropic sib tshuam, whereas lub lwg taw tes thiab npuas taw tes ntawm zeotropic sib tov yog qhov txawv.
