Kev piav qhia: Tshuaj cov khoom yog cov uas tsuas yog tsim los ntawm kev nqa tawm a tshuaj cov tshuaj tiv thaiv (kub ntawm combustion, flash point, enthalpies ntawm tsim, thiab lwm yam). Qhov ntom tuaj yeem tsim tau yooj yim los ntawm kev txiav txim siab qhov loj thiab ntim ntawm cov khoom, tsis muaj kev cuam tshuam cuam tshuam, yog li nws a khoom ntiag tug.
Xav txog qhov no, qhov ceev yog lub cev lossis tshuaj lom neeg?
Tus general khoom ntawm cov teeb meem xws li xim, ceev , hardness, yog piv txwv ntawm lub cev khoom . Cov khoom uas piav qhia txog yuav ua li cas cov khoom hloov pauv mus rau hauv cov khoom sib txawv kiag li hu ua tshuaj muaj zog . Flammability thiab corrosion / oxidationresistance yog cov piv txwv ntawm tshuaj muaj zog.
Tsis tas li ntawd, vim li cas qhov ntom ntom yog lub cev muaj zog? Dab tsi yog ceev , thiab vim li cas thiaj suav tias yog a khoom ntiag tug tsis yog tshuaj vaj tse yam tseem ceeb? Nws suav tias yog a khoom ntiag tug vim qhov loj / ntim. Nws yog intensive khoom ntiag tug vim koj ntsuas tau ceev ntawm kev daws yam tsis hloov nws cov tshuaj txheeb xyuas, nws pom tau.
Ib sab ntawm qhov no, puas yog qhov kev hloov ntawm qhov ntom ntom ntawm cov tshuaj hloov pauv?
Ntim Hloov Txhua tshuaj compound muaj qhov tshwj xeeb ceev . Yog tias tshuaj compound kev hloov vim a tshuaj tiv thaiv , cov kev hloov ceev ib yam nkaus. Qhov no ua rau lub ntim ntawm cov khoom lag luam rov qab los yog nthuav dav thaum lub sijhawm tshuaj tiv thaiv txheej txheem.
Puas yog flammability hloov lub cev lossis tshuaj lom neeg?
Teb thiab piav qhia: Flammability yog a chemical khoom , los yog ib qho uas tuaj yeem pom thaum asubstance kev hloov rau hauv lwm yam. Piv txwv li, ntawv yog nplaim taws.

Puas yog huab cua hloov pauv lub cev lossis tshuaj lom neeg?
Kev hloov ntawm lub xeev yog kev hloov ntawm lub cev hauv qhov teeb meem. Lawv yog cov kev hloov pauv uas tsis hloov qhov teeb meem tshuaj pleev lossis tshuaj lom neeg. Piv txwv li, thaum huab cua hloov mus rau dej vapor, nws tseem yog dej thiab tuaj yeem hloov rov qab mus rau cov kua dej dua
Puas yog hluav taws kub nyhiab yog qhov hloov pauv ntawm lub cev lossis tshuaj lom neeg?
Thaum cov roj hlawv nws feem ntau ua ke nrog oxygen kom muab cov pa roj carbon dioxide, dej thiab lwm yam nrog rau kev tso tawm ntawm lub zog. Los ntawm kev txhais, nws yog kev hloov tshuaj
Dab tsi yog qhov ntom ntom ntom ntom ntom ntom ntom?
Ib daim phiaj density yog ib qho piv txwv ntawm kev faib cov lej sib txawv. Nws yuav siv ib ntsiav ceev kwv yees los qhia qhov tshwm sim ceev muaj nuj nqi ntawm lub nce mus nce los (saib ntxiv). Nws yog ib tug smoothed version ntawm lub histogram thiab yog siv nyob rau hauv tib lub tswvyim
Dab tsi yog qhov txawv ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom nrog cov piv txwv?
Nws ua haujlwm nyob rau hauv ob qho tib si loj thiab me me thiab tsis yog raws li cov pej xeem ceev. Ceev dependent yam yog cov uas tswj cov kev loj hlob ntawm ib tug pej xeem nyob rau ntawm nws lub ceev thaum ceev ywj siab yam yog cov uas tswj pejxeem kev loj hlob yam tsis muaj nyob rau nws cov ceev
Puas muaj kev hloov pauv ntawm lub cev lossis tshuaj lom neeg thaum muaj suab thaj yaj hauv dej?
Dissolving qab zib hauv dej yog ib qho piv txwv ntawm kev hloov lub cev. Nov yog vim li cas: Kev hloov tshuaj lom neeg tsim cov khoom siv tshuaj tshiab. Txhawm rau kom qab zib hauv dej los ua cov tshuaj hloov pauv, ib yam tshiab yuav tsum tau ua. Yog tias koj evaporate cov dej los ntawm cov kua qab zib-dej, koj nyob nraum nrog qab zib
