Cov piv txwv zoo ntawm lub cev muaj xws li qhov ntom ntom, xim, hardness, melting thiab boiling point, thiab hluav taws xob conductivity. … Piv txwv ntawm cov khoom muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion.
Vim li cas qhov ntom ntom yog cov khoom siv tshuaj?
Txoj Kev Ntsig yog suav tias yog lub cev khoomas; Qhov ntom yog qhov piv ntawm qhov hnyav rau qhov ntim ntawm cov khoom. … Qhov ntom ntawm ib yam khoom tseem nyob tas li thiab tsis nyob ntawm seb muaj pes tsawg ntawm cov khoom. Tsis tas li ntawd, cov tshuaj tsis tas yuav tsum muaj cov tshuaj tiv thaiv rau kev txheeb xyuas nws qhov ntom.
Puas yog qhov ntom ntom ntawm lub cev lossis tshuaj lom neeg?
A lub cev khoom yog ib yam ntawm cov teeb meem uas tsis cuam tshuam nrog kev hloov pauv hauv nws cov tshuaj muaj pes tsawg leeg. Cov piv txwv paub ntawm lub cev muaj xws li qhov ntom ntom, xim, hardness, melting thiab boiling point, thiab hluav taws xob conductivity.
Puas yog cov khoom muaj tshuaj lom neeg?
Cov khoom siv tshuaj yog cov uas tuaj yeem tsim los ntawm kev ua cov tshuaj tiv thaiv (kub ntawm combustion, flash point, enthalpies ntawm kev 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 cov tshuaj tiv thaiv, yog li nws yog lub cev khoom
Puas yog qhov ntom ntom yog cov khoom siv tshuaj lom neeg?
Cov khoom siv dav dav xws li xim, ntom ntom, tawv, yog cov piv txwv ntawm lub cev muaj zogCov khoom uas piav qhia tias cov tshuaj hloov pauv mus rau hauv cov khoom sib txawv kiag li hu ua cov khoom siv tshuaj. Flammability thiab corrosion / oxidation kuj yog cov piv txwv ntawm cov khoom siv tshuaj.
