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.
