Qhov sib txawv tseem ceeb ntawm qhov taw tes flash thiab nws pib ignition kub yog qhov flash point txiav txim siab qhov ntsuas kub qis tshaj ntawm qhov vapor ntawm cov khoom pib ignition nyob rau hauv lub xub ntiag ntawm ib tug ignition qhov twg nws pib ignition kub yog qhov qis tshaj qhov kub ntawm cov khoom. tuaj yeem pib ignition spontaneously.
Ob qho tib si flash point thiab nws pib ignition kub yog cuam tshuam nrog cov khoom siv hluav taws xob ntawm qhov kub qis tshaj plaws.
Flash Point yog dab tsi?
Lub teeb nyem ntawm cov khoom tshwj xeeb yog qhov kub qis tshaj plaws ntawm cov khoom vapor ntawm cov khoom siv hluav taws xob nyob rau hauv qhov muaj qhov hluav taws kub. Feem ntau, cov ntsiab lus hluav taws kub taw tes thiab flash point tsis meej pem vim lawv zoo li qub. Tab sis, qhov hluav taws kub muab qhov kub qis tshaj plaws uas cov vapor ntawm cov khoom tuaj yeem ua kom kub hnyiab tau thaum peb tshem tawm qhov hluav taws kub, uas txawv kiag li ntawm lub ntsiab lus ntawm lub teeb nyem.
Thaum xav txog qhov hluav taws kub ntawm vapor ntawm lub teeb nyem, muaj vapor txaus los ua kom muaj hluav taws kub thaum peb muab qhov hluav taws kub. Cov kua dej volatile muaj qhov tshwj xeeb ntawm cov nplaim hluav taws kub, uas yog qhov tsim nyog rau kev txhawb nqa kev sib txuas hauv huab cua.
Yog peb ntsuas qhov taw tes ntawm cov khoom, muaj ob txoj hauv kev: qhib khob ntsuas thiab ntsuas khob kaw. Tsis tas li ntawd, cov txheej txheem ntawm kev txiav txim siab lub teeb nyem tau teev nyob rau hauv ntau tus qauv.
Dab tsi yog Auto-Ignition Temperature?
Nws pib qhov hluav taws kub kub yog qhov kub qis tshaj plaws uas cov khoom siv tuaj yeem pib hluav taws kub nyhiab. Ntawm no, cov khoom pib hlawv yam tsis muaj kev cuam tshuam ntawm qhov hluav taws xob sab nraud, thiab qhov hluav taws kub no tshwm sim ntawm cov huab cua ib puag ncig tshwj tsis yog qhov kub thiab txias. Qhov kub thiab txias muab lub zog ua kom lub zog yuav tsum tau pib combustion.
Feem ntau, qhov kub thiab txias yuav tsum tau pib qhov hluav taws kub tshwm sim nyob ntawm qhov siab ntawm cov khoom. Kev nce siab txo qhov kub ntawm qhov pib ignition. Ntxiv mus, thaum cov pa oxygen concentration yog nce, qhov pib-ignition kub txo vim muaj cov pa txaus txaus ua rau nws yooj yim rau ignite spontaneously. Qee qhov piv txwv muaj raws li hauv qab no:
- Barium (550°C)
- Bismuth (735°C)
- Butane (405°C)
- Calcium (790°C)
- Carbon disulfide (90 ° C)
Qhov txawv ntawm Flash Point thiab Nws Pib Ignition Kub yog dab tsi?
Ob qho tib si flash point thiab nws pib ignition kub muaj feem xyuam rau cov khoom siv hluav taws xob ntawm qhov kub qis tshaj plaws. Qhov sib txawv tseem ceeb ntawm flash point thiab nws pib ignition kub yog tias flash point txiav txim siab qhov qis tshaj plaws ntawm qhov vapor ntawm cov khoom pib ignition nyob rau hauv lub xub ntiag ntawm qhov hluav taws xob qhov hluav taws xob whereas nws pib ignition kub yog qhov qis tshaj qhov kub ntawm cov khoom yuav pib ignition spontaneously.
Ntxiv mus, lwm qhov sib txawv tseem ceeb ntawm qhov chaw taws teeb thiab qhov kub ntawm qhov pib qhov hluav taws xob yog qhov chaw taws teeb yuav tsum muaj cov khoom siv hluav taws xob sab nraud thaum nws pib ignition kub tsis tas yuav muaj qhov hluav taws kub sab nraud. Tsis tas li ntawd, lub siab tsis muaj qhov cuam tshuam ntawm qhov taw tes thaum qhov nce ntawm lub siab txo qis atuo ignition kub.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm qhov chaw taws teeb thiab qhov kub ntawm qhov pib kub.
Summary – Flash Point vs Auto Ignition Temperature
Ob qho tib si flash point thiab nws pib ignition kub yog cuam tshuam nrog cov khoom siv hluav taws xob ntawm qhov kub qis tshaj plaws. Qhov sib txawv tseem ceeb ntawm flash point thiab nws pib ignition kub yog tias flash point txiav txim siab qhov qis tshaj plaws ntawm qhov vapor ntawm cov khoom pib ignition nyob rau hauv lub xub ntiag ntawm qhov hluav taws xob qhov hluav taws xob whereas nws pib ignition kub yog qhov qis tshaj qhov kub ntawm cov khoom yuav pib ignition spontaneously.
