Methanol Density: Kev Ntsuam Xyuas Kev Tshawb Fawb thiab Daim Ntawv Thov
Methanol, ua ib qho tseem ceeb ntawm cov organic compound, muaj ntau yam kev siv hauv kev lag luam tshuaj. Kev nkag siab txog lub cev lub cev ntawm methanol, xws li qhov ceev ntawm methanol, yog qhov tseem ceeb heev rau kev tsim tshuaj, khaws cia thiab thauj. Hauv tsab xov xwm no, peb yuav tham txog cov ntsiab lus ntawm methanol ntom ntom, nws cov yam ntxwv cuam tshuam thiab nws qhov tseem ceeb hauv kev siv tswv yim.
Basic tswvyim ntawm methanol ceev
Qhov ceev ntawm methanol yog qhov loj ntawm methanol rau ib chav tsev ntim, feem ntau qhia hauv grams ib cubic centimeter (g / cm³) los yog kilograms ib cubic meter (kg / m³). Raws li cov qauv txheej txheem, qhov ceev ntawm methanol ntawm 20 ° C yog kwv yees li 0.7918 g / cm³. Tus nqi ntom ntom no ua rau methanol sib dua li dej (uas muaj qhov ntom ntom ntawm 1 g / cm³), uas nyob rau hauv ntau daim ntawv thov txhais tau tias sib txawv tuav thiab khaws cia.
Cov yam ntxwv cuam tshuam rau qhov ntom ntawm methanol
Qhov kub thiab txias
Qhov kub thiab txias yog ib qho tseem ceeb cuam tshuam rau qhov ntom ntawm methanol. Raws li qhov kub thiab txias, qhov molecular txav ntawm methanol nce, qhov ntim nthuav dav thiab qhov ntom ntom. Hloov pauv, thaum qhov kub thiab txias qis, lub zog molecular qeeb thiab qhov ceev ntawm methanol nce. Yog li ntawd, nyob rau hauv kev xyaum, tshuaj tuam txhab uas muag feem ntau kho tus tsim thiab muaj peev xwm ntawm cia khoom raws li qhov kub thiab txias ambient.
Kev cuam tshuam ntawm purity
Lub purity ntawm methanol kuj ncaj qha cuam tshuam nws qhov ntom. Hauv kev tsim khoom lag luam, methanol tuaj yeem sib xyaw nrog cov kab dej lossis lwm yam impurities, uas feem ntau hnyav dua lossis sib dua li methanol, yog li hloov tag nrho qhov ntom ntawm methanol. Yog li ntawd, kev tswj cov purity ntawm methanol yog ib qho tseem ceeb nyob rau hauv qhov ceev-sensitive daim ntawv thov scenarios.
Daim ntawv thov scenarios rau methanol ntom
Kev siv tshuaj lom neeg ntau lawm
Cov ntaub ntawv tseeb ntawm methanol ntom ntom yog qhov tseem ceeb rau kev siv tshuaj thiab tshuaj tiv thaiv kev tswj xyuas thaum lub sijhawm tsim tshuaj. Ntau cov tshuaj tiv thaiv muaj kev nruj me ntsis rau cov concentration ntawm reactants, uas feem ntau txiav txim siab los ntawm qhov ceev. Piv txwv li, nyob rau hauv cov tshuaj tiv thaiv methanol-rau-formaldehyde, kev ntsuas qhov tseeb yog pab xyuas kom meej qhov ua tau zoo ntawm cov tshuaj tiv thaiv thiab cov purity ntawm cov khoom.
Kev siv hauv kev khaws cia thiab thauj
Methanol density cuam tshuam rau kev tsim cov tank cia thiab cov thawv thauj khoom. Thaum lub sij hawm thauj mus los, qhov ntom ntom tsawg txhais tau hais tias methanol hnyav dua rau tib lub ntim, uas tuaj yeem txo cov nqi thauj khoom. Kev nkag siab txog qhov ntom ntom ntawm methanol kuj tseem tuaj yeem pab txhim kho kev tsim cov khoom siv khaws cia kom ruaj ntseg thiab tiv thaiv kom tsis txhob tawg.
Hauv cov ntsiab lus
Qhov ntom ntawm methanol tsis yog tsuas yog cov cuab yeej ntawm lub cev, tab sis kuj tseem ceeb heev rau kev siv tshuaj lom neeg, khaws cia thiab thauj. Kev nkag siab thiab raug siv cov ntaub ntawv methanol ntom ntom tsis tsuas yog txhim kho kev tsim khoom, tab sis kuj tseem tswj tau cov nqi thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm. Rau cov kws tshaj lij kev lag luam tshuaj, kev paub txog methanol ntom ntom yog ib qho tseem ceeb ntawm lawv cov kev txawj ntse.
