Acetoneyog ib hom tshuaj siv dav siv nrog ntau yam kev lag luam thiab kev siv hauv tsev.Nws muaj peev xwm yaj ntau yam tshuaj thiab nws compatibility nrog ntau yam ntaub ntawv ua rau nws ib tug mus-rau kev daws rau ntau yam dej num, los ntawm tshem tawm 指甲 roj mus tu iavware.Txawm li cas los xij, nws qhov profile flammability feem ntau tso cov neeg siv thiab cov kws tshaj lij kev nyab xeeb zoo ib yam nrog cov lus nug hlawv.Puas yog 100% acetone flammable?Kab lus no delves rau hauv kev tshawb fawb tom qab lo lus nug no thiab tshawb nrhiav qhov txaus ntshai thiab qhov tseeb cuam tshuam nrog kev siv cov acetone ntshiab.

Yuav kom nkag siab txog qhov flammability ntawm acetone, peb yuav tsum xub xyuas nws cov qauv tshuaj.Acetone yog peb-carbon ketone uas muaj ob qho tib si oxygen thiab carbon, ob ntawm peb lub ntsiab lus tsim nyog rau cov nplaim taws (qhov thib peb yog hydrogen).Qhov tseeb, acetone's chemical formula, CH3COCH3, muaj ob qho tib si thiab ob daim ntawv cog lus ntawm carbon atoms, muab lub sijhawm rau cov tshuaj tiv thaiv dawb-radical uas tuaj yeem ua rau combustion.

Txawm li cas los xij, vim hais tias ib yam khoom muaj cov khoom siv hluav taws xob tsis tas txhais tau tias nws yuav hlawv.Cov xwm txheej rau flammability kuj muaj xws li ib tug concentration pib thiab muaj ib tug ignition qhov chaw.Nyob rau hauv cov ntaub ntawv ntawm acetone, qhov pib no ntseeg tau tias nyob nruab nrab ntawm 2.2% thiab 10% los ntawm qhov ntim hauv huab cua.Hauv qab no concentration, acetone yuav tsis ignite.

Qhov no coj peb mus rau ntu thib ob ntawm cov lus nug: cov xwm txheej uas acetone hlawv.Ntshiab acetone, thaum raug rau qhov hluav taws kub xws li lub txim taws lossis nplaim taws, yuav kub hnyiab yog tias nws cov concentration nyob rau hauv qhov hluav taws kub.Txawm li cas los xij, qhov kub hnyiab ntawm acetone kuj qis dua piv rau ntau lwm cov roj, ua rau nws tsis tshua muaj kev kub nyhiab hauv qhov chaw kub.

Tam sim no cia peb xav txog qhov cuam tshuam tiag tiag ntawm qhov kev paub no.Hauv feem ntau hauv tsev thiab chaw tsim khoom, cov acetone ntshiab tsis tshua pom muaj nyob rau hauv cov ntsiab lus siab txaus los ua cov nplaim taws.Txawm li cas los xij, hauv qee cov txheej txheem kev lag luam lossis cov ntawv siv hnyav uas siv cov acetone siab, yuav tsum tau ceev faj ntxiv kom muaj kev nyab xeeb.Cov neeg ua haujlwm tuav cov tshuaj no yuav tsum raug cob qhia zoo hauv kev coj ua kom muaj kev nyab xeeb, suav nrog kev siv cov khoom siv hluav taws xob tiv thaiv hluav taws thiab tiv thaiv cov khoom siv hluav taws xob nruj.

Hauv kev xaus, 100% acetone yog flammable nyob rau hauv tej yam kev mob tab sis tsuas yog thaum nws concentration nyob rau hauv ib tug tshwj xeeb ntau yam thiab nyob rau hauv lub xub ntiag ntawm ib tug ignition qhov chaw.Nkag siab txog cov xwm txheej no thiab ua raws li kev ntsuas kev nyab xeeb yuav pab tiv thaiv kom tsis txhob muaj hluav taws kub los yog tawg uas tshwm sim los ntawm kev siv cov tshuaj lom neeg no.
