Distillation yog cov txheej txheem sib cais uas siv kom zoo dua ntawm qhov kub ntawm cov khoom sib xyaw. Txhawm rau ua kom distillation, sib tov miscible ntawm ob lub kua nrog qhov sib txawv tseem ceeb hauv cov ntsiab lus kub - tsawg kawg 20 °C - yog rhuab.
Dab tsi yog qhov ntsuas kub thaum lub sijhawm distillation?
Distilling cawv siv qhov kub siab - feem ntau ncig 200 degrees Fahrenheit. Qhov kub thiab txias txhais tau tias muaj kev sib tsoo, yog li xyuas kom txhua tus neeg nyob hauv koj qhov chaw distilling paub txog tias koj cov cuab yeej kub npaum li cas.
Puas kub tseem ceeb hauv distillation?
Kev tswj kub muaj feem xyuam rau cov khoom zoo, kev ua kom zoo dua qub thiab ruaj khov, ua rau cov nroj tsuag muaj kev nyab xeeb thiab txo cov nqi hluav taws xob. Txawm hais tias qhov zoo li qhov tsis yooj yim, kev nkag siab qhov tseem ceeb ntawm kev ntsuas qhov kub thiab txias yog qhov tseem ceeb rau kev khiav ntawm kab distillation at peak efficiency.
Yuav ua li cas thaum cov kua ua kom sov hauv qhov yooj yim distillation?
Yooj yim distillation ua haujlwm vim tias cov kuab tshuaj yaj muaj qhov kub kub ntau dua li cov kuab tshuaj. Thaum cov tshuaj yog rhuab, kuab vapor evaporates los ntawm cov tshuaj. … Cov tshuaj uas tseem tshuav ua kom muaj zog ntau dua hauv cov kuab tshuaj raws li cov kuab tshuaj hauv nws txo qis.
Vim li cas qhov kub thiab txias nyob tas li thaum lub sijhawmdistillation?
Qhov kub tseem nyob tas li vim lub zog ntxiv nkag mus rau hauv chav khiav tawm, thiab tsis mus rau qhov kub ntawm dej. Chav ntawm 1ny muab qhov kub thiab txias muaj zog ntau dua li cov dej ua kua ntawm qhov kub thiab txias.

Puas yog qhov kub thiab txias cuam tshuam qhov zaus ntawm cov yeeb nkab hauv nruab nrog cev?
Qhov cuam tshuam ntawm cua sov ntawm cov yeeb nkab zaus ntau dua li qhov nce ntawm qhov ntev ntawm cov yeeb nkab kom qhov zaus ntawm cov yeeb nkab hauv nruab nrog cev nce ntxiv thaum kub nce. Thaum kub nce zaus ntawm cov yeeb nkab hauv nruab nrog cev?
Yuav tsum lub tub yees txias txias khiav txhua lub sijhawm?
Yog lub tub yees tsis txias txaus, nws yuav ua haujlwm hnyav dua kom txias. Vim li ntawd, nws yuav khiav tas li. Lub freezer kub yuav tsum tau teem ntawm 0 txog 5 degrees Fahrenheit (-18 txog -15C). Kuv lub tub yees Whirlpool yuav tsum khiav ntau npaum li cas?
Lub sijhawm hloov ntawm lub xeev qhov kub thiab txias tseem nyob li qub?
Qhov kub tseem nyob tas li thaum lub sijhawm hloov pauv vim tias tshav kub lub zoguas tau muab los hloov lub xeev cov teeb meem yog siv los rhuav tshem cov rog intermolecular thiab lwm yam txaus nyiam. … Li no qhov kub tseem nyob tas li vim txhua qhov cua sov tau siv thiab tsis muaj cua sov sab nraud tawm los yog nqus tau.
Puas yog qhov kub thiab txias cuam tshuam rau cov kua Newtonian?
Qhov ntsuas kub ntawm qhov viscosity ntawm Newtonian kua yog xws li qhov viscosity txo qis nrog qhov kub thiab txias, thiab feem ntau, qhov viscosity siab dua, qhov ntau dua qhov txo qis nrog qhov kub thiab txias.. … Lub viscosity ntawm cov kua yuav luag ib txwm nce nrog lub siab, nrog rau dej yog ib qho kev zam.
Lub sijhawm txias txias austenite hloov mus rau?
Thaum lub sijhawm hloov pauv ferrite, cov pa roj carbon diffuses rau hauv austenite, uas ua rau kom muaj zog ntawm theem no. Lub hom phiaj ntawm lub caij txias ceev yog hloov pauv cov austenite ntxiv mus rau martensite. Qhov kub npaum li cas ua qhov kawg austenite hloov pauv ntawm qhov txias?
