Isopropanol Ceev: Nkag siab thiab Nws Daim Ntawv Thov hauv Kev Lag Luam Tshuaj
Isopropanol, tseem hu ua isopropyl cawv los yog IPA, yog ib hom organic compound siv nyob rau hauv ntau yam tshuaj, tshuaj thiab tshuaj pleev ib ce. Hauv tsab xov xwm no, peb yuav ua tib zoo saib cov ncauj lus ntawm isopropanol ntom ntom kom pab koj nkag siab tag nrho cov cuab yeej ntawm lub cev thiab nws qhov tseem ceeb hauv kev siv tiag tiag hauv ntiaj teb.
Isopropyl Alcohol Density yog dab tsi?
Qhov ceev ntawm isopropyl cawv yog qhov loj ntawm isopropyl cawv ib chav tsev ntim, feem ntau qhia hauv grams ib cubic centimeter (g / cm³). Qhov ntom ntom yog qhov tseem ceeb ntawm cov khoom siv lub cev ntawm cov kua, uas cuam tshuam los ntawm qhov kub thiab txias. Raws li tus qauv (20 ° C, 1 atm), qhov ceev ntawm isopropanol yog kwv yees li 0.785 g / cm³. Tus nqi no yuav txawv ntawm qhov kub thiab txias, yog li nws yog ib qho tseem ceeb kom nkag siab thiab kho qhov ntom ntawm isopropyl cawv hauv cov ntawv thov sib txawv.
Qhov tseem ceeb ntawm Isopropyl cawv ntom ntom
Kev ntsuas qhov tseeb ntawm qhov ntom ntawm isopropyl cawv yog qhov tseem ceeb rau kev tsim tshuaj thiab kev siv tshuaj. Qhov ntom ntom tsis tsuas yog cuam tshuam rau qhov sib piv ntawm qhov sib tov, tab sis kuj tseem cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov tshuaj tiv thaiv thiab qhov zoo ntawm cov khoom. Piv txwv li, nyob rau hauv cov tshuaj tiv thaiv, qhov ntom ntawm isopropanol yuav cuam tshuam rau viscosity ntawm cov tshuaj, uas nyob rau hauv lem cuam tshuam rau huab hwm coj hloov mus thiab cov tshuaj tiv thaiv. Paub qhov ceev ntawm isopropanol pab txhim kho cov txheej txheem tsis zoo thiab xyuas kom meej tias cov tshuaj tiv thaiv tuaj yeem tshwm sim hauv cov xwm txheej zoo.
Kev hloov pauv ntawm isopropanol ntom ntom ntawm qhov kub sib txawv
Raws li tau hais ua ntej, qhov ceev ntawm isopropanol txo qis thaum kub nce. Qhov no yog vim qhov nce ntawm qhov kub thiab txias ua rau qhov kev ncua deb ntawm molecules nce, uas txo qhov ntom ntawm cov kua. Tshwj xeeb, ntawm 20 ° C, isopropyl cawv muaj qhov ceev ntawm 0.785 g / cm³, thaum nyob rau ntawm 40 ° C, nws qhov ceev txo mus rau kwv yees li 0.774 g / cm³. Qhov kev hloov pauv no yog qhov tseem ceeb tshwj xeeb hauv cov tshuaj zoo, tshuaj thiab biotechnology sectors, qhov tseeb ntawm cov khoom siv raw yog qhov tseem ceeb heev thiab kev hloov me me ntawm qhov ntom tuaj yeem cuam tshuam rau cov khoom kawg.
Yuav ntsuas thiab kho li cas isopropyl cawv ntom ntom
Kev ntsuas ntawm isopropanol ntom ntom feem ntau yog ua los ntawm kev siv lub raj mis tshwj xeeb los yog lub ntsuas qhov densitometer. Hauv kev xyaum, kev tswj xyuas meej ntawm qhov ceev ntawm isopropanol tuaj yeem ua tiav los ntawm kev kho qhov kub lossis qhov sib tov sib xyaw. Rau cov txheej txheem tshuaj lom neeg uas xav tau kev ua haujlwm siab, nws yog ib qho kev coj ua los saib xyuas qhov ceev ntawm lub sijhawm tiag tiag thiab hloov kho kom haum. Qhov no tsis tsuas yog txhim kho kev tsim khoom, tab sis kuj ua kom cov khoom zoo thiab sib xws.
Cov ntsiab lus
Isopropanol ntom ntom yog ib qho tseem ceeb ntawm lub cev tsis zoo hauv kev lag luam chemical thiab muaj ntau yam cuam tshuam rau kev siv tswv yim. Kev nkag siab txog qhov ntom ntom ntawm isopropanol thiab nws qhov ntsuas kub ntawm qhov ntsuas kub yog qhov tseem ceeb rau kev txhim kho cov txheej txheem tsim khoom thiab txhim kho cov khoom zoo. Hauv kev tsim tshuaj lom neeg, kev tswj xyuas meej ntawm isopropanol ntom ntom tuaj yeem ua rau muaj kev ua tau zoo dua thiab ruaj khov ntawm cov khoom lag luam. Yog li ntawd, kev nkag siab tob thiab siv tau ntawm qhov kev ntsuas no yuav ua rau muaj kev sib tw tseem ceeb rau cov tuam txhab tshuaj.
