Acetone ntom ntom: qhov tob saib thiab nws cov kev siv
Acetone, raws li ib qho tseem ceeb organic compound, yog dav siv nyob rau hauv ntau industries xws li tshuaj, tshuaj thiab coatings. Hauv cov teb no, nws yog qhov tseem ceeb tshwj xeeb kom nkag siab thiab paub qhov ceev ntawm acetone, vim nws cuam tshuam ncaj qha rau cov khoom sib piv, hnyav siv thiab cov khoom zoo thiab lwm yam tseem ceeb. Hauv daim ntawv no, peb yuav tham txog cov ntsiab lus tseem ceeb ntawm acetone ntom ntom, cov yam ntxwv cuam tshuam thiab siv tau.
1. Acetone ceev ntawm cov ntsiab lus yooj yim
Acetone ntom yog hais txog qhov loj ntawm acetone ib chav tsev ntim, nws tus qauv ntom ntawm chav tsev kub thiab siab yog li 0.784 g / cm³. Kev ntsuas ntawm qhov ntom yog ntau tshaj li tus lej yooj yim, nws qhia txog qib ntawm compactness ntawm acetone molecules thiab kev faib tawm ntawm cov khoom loj. Kev paub txog cov ntaub ntawv yooj yim ntawm acetone ntom ntom yog qhov tseem ceeb rau kev tswj xyuas meej ntawm cov concentration thiab sib tov piv ntawm cov tshuaj.
2. Cov nyhuv ntawm qhov kub thiab txias ntawm qhov ntom ntawm acetone
Qhov kub thiab txias yog qhov tseem ceeb cuam tshuam rau qhov ntom ntawm acetone. Feem ntau, qhov ceev ntawm acetone txo qis thaum qhov kub nce. Qhov no yog vim qhov nce ntawm qhov kub thiab txias ua rau muaj qhov nce ntawm qhov sib txawv ntawm qhov sib txawv, uas ua rau txo qis ntawm cov molecules ntawm ib chav tsev ntim thiab txo qhov ceev. Rau kev lag luam tshuaj, kev tswj qhov kub thiab txias yog qhov tseem ceeb hauv cov txheej txheem tsim khoom, yog li kev paub meej ntawm acetone ntom ntom hauv qhov kub sib txawv yog lub hauv paus rau kev ua kom cov khoom zoo.
3. Acetone ceev nyob rau hauv qhov tseem ceeb ntawm cov ntawv thov kev lag luam
Acetone ntom ntom hauv kev lag luam hauv ntau hom kev siv. Piv txwv li, nyob rau hauv kev lag luam coatings, qhov ceev yuav cuam tshuam cov fluidity ntawm cov xim thiab ziab ceev; Hauv kev lag luam kws tshuaj, acetone ua cov kuab tshuaj, kev hloov pauv ceev tuaj yeem cuam tshuam rau purity thiab stability ntawm cov tshuaj. Kev ntsuas qhov tseeb ntawm qhov ntom ntawm acetone yuav tsum tsis txhob saib xyuas hauv cov khoom sib npaug hauv kev tsim khoom, khaws cia thiab thauj. Piv txwv li, thaum khaws cia acetone, cov kev hloov ntawm qhov ntom yuav ua rau muaj kev hloov pauv hauv ntim, yog li cuam tshuam rau kev xaiv thiab siv cov ntim khoom.
4. Yuav ntsuas thiab xam qhov ceev ntawm acetone li cas
Cov txheej txheem ntawm kev ntsuas qhov ntom ntawm acetone suav nrog txoj kev nqus lub raj mis tshwj xeeb, txoj kev buoyancy thiab cov txheej txheem digital densitometer. Qhov kev xaiv ntawm txhua txoj kev yog nyob ntawm qhov ntsuas qhov tseeb uas yuav tsum tau ua thiab cov kev ua haujlwm tshwj xeeb. Feem ntau, digital densitometer tuaj yeem siv kom tau txais tus nqi nrawm thiab raug ntawm acetone ntom ntom, tshwj xeeb tshaj yog rau kev saib xyuas cov kab ntau lawm. Kev kho qhov siab thiab qhov kub thiab txias kuj yuav tsum tau txiav txim siab thaum xam cov acetone ntom kom ntseeg tau qhov tseeb ntawm cov txiaj ntsig.
Xaus
Acetone ntom ntom, raws li cov cuab yeej tseem ceeb ntawm lub cev, tsis yog tsuas yog qhov tseem ceeb, tab sis kuj siv dav hauv kev coj ua hauv ntau lub lag luam. Kev nkag siab thiab paub qhov ceev ntawm acetone yog qhov tseem ceeb rau kev txhim kho cov txheej txheem, txhim kho cov khoom zoo thiab ua kom muaj kev nyab xeeb. Yog li ntawd, nyob rau hauv kev xyaum, ntxiv rau mastering tus txheej txheem tus nqi ntawm acetone ceev, nws tseem yuav tsum tau tag nrho xav txog qhov kub thiab txias, siab thiab lwm yam tseem ceeb nyob rau hauv thiaj li yuav txiav txim siab thiab daim ntawv thov.
