Lo lus nug "Puas acetone yaj yas?"yog ib qho uas ib txwm hnov, feem ntau hnov ​​hauv tsev neeg, kev cob qhia, thiab kev tshawb fawb.Cov lus teb, raws li nws hloov tawm, yog ib qho nyuaj, thiab tsab xov xwm no yuav delve rau hauv cov ntsiab lus tshuaj thiab cov tshuaj tiv thaiv uas cuam tshuam qhov tshwm sim no.

acetoneyog ib qho yooj yim organic compound uas belongs rau tsev neeg ketone.Nws muaj cov tshuaj formula C3H6O thiab paub zoo tias nws muaj peev xwm yaj tej yam yas.Yas, ntawm qhov tod tes, yog ib lo lus dav uas npog ntau yam khoom siv los ntawm tib neeg.Lub peev xwm ntawm acetone los yaj cov yas yog nyob ntawm hom yas koom nrog.

Thaum acetone los rau hauv kev sib cuag nrog qee hom yas, tshuaj lom neeg tshwm sim.Cov yas molecules yog attracted rau cov acetone molecules vim lawv cov polar xwm.Qhov kev nyiam no ua rau cov yas ua liquefied, uas ua rau "melting" nyhuv.Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias qhov no tsis yog txheej txheem melting tiag tiag tab sis yog kev sib cuam tshuam tshuaj lom neeg.

Qhov tseem ceeb ntawm no yog polarity ntawm cov molecules koom nrog.Polar molecules, xws li acetone, muaj ib feem zoo thiab ib nrab tsis zoo nqi faib nyob rau hauv lawv cov qauv.Qhov no tso cai rau lawv sib cuam tshuam thiab sib txuas nrog cov khoom polar zoo li qee hom yas.Los ntawm qhov kev cuam tshuam no, cov qauv yas molecular raug cuam tshuam, ua rau nws pom meej "melting".

Tam sim no, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm ntau hom yas thaum siv acetone ua cov kuab tshuaj.Txawm hais tias qee cov yas xws li polyvinyl chloride (PVC) thiab polyethylene (PE) muaj qhov cuam tshuam rau acetone lub ncov qaumteb qabteb attraction, lwm yam xws li polypropylene (PP) thiab polyethylene terephthalate (PET) yog tsawg reactive.Qhov sib txawv ntawm qhov reactivity no yog vim muaj cov qauv tshuaj sib txawv thiab cov polarities ntawm cov yas sib txawv.

Lub sijhawm ntev ntawm cov yas rau acetone yuav ua rau muaj kev puas tsuaj mus tas li lossis degradation ntawm cov khoom.Qhov no yog vim hais tias cov tshuaj tiv thaiv ntawm acetone thiab yas yuav hloov cov qauv molecular ntawm lub tom kawg, ua rau kev hloov nyob rau hauv nws lub cev zog.

acetone lub peev xwm los "kua" yas yog los ntawm cov tshuaj tiv thaiv ntawm lub ncov qaumteb qabteb acetone molecules thiab qee hom polar yas.Cov tshuaj tiv thaiv no cuam tshuam cov yas cov qauv molecular, ua rau nws pom tseeb liquefaction.Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev raug acetone ntev ntev tuaj yeem ua rau muaj kev puas tsuaj mus tas li lossis degradation ntawm cov khoom yas.
