Cov khoom dav dav ntawm cov teeb meem xws li xim, ntom ntom, hardness, yog cov piv txwv ntawm lub cev. 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 cov khoom siv tshuaj. Flammability thiab corrosion / oxidation kuj yog cov piv txwv ntawm cov khoom siv tshuaj.
Puas toxicity yog lub cev lossis tshuaj lom neeg?
Kev hloov ntawm ib hom teeb meem mus rau lwm yam (lossis tsis muaj peev xwm hloov tau) yog tshuaj muaj tshuaj. Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion.
Puas yog qhov ductility yog lub cev lossis tshuaj lom neeg?
khoom uas hais tias yog ductility yog ib tug lub cev khoomuas yog ntawm ib yam khoom uas muaj feem xyuam nrog lub peev xwm yuav hammered nyias los yog peb hais tau stretched rau hauv hlau tsis tawg nws. Muaj ib yam khoom ductile tuaj yeem rub mus rau hauv ib lub xaim.
Puas viscosity yog lub cev lossis tshuaj lom neeg?
Txhua yam yam ntxwv ntawm cov khoom uas koj tuaj yeem soj ntsuam yam tsis hloov tus kheej ntawm cov khoom yog lub cev khoomQee qhov piv txwv ntawm lub cev muaj zog yog boiling point, melting point, viscosity, ntom., hardness, malleability, solubility, zoo, loj, thiab xim.
Puas yog solubility yog tshuaj los yog lub cev khoom?
yam ntxwv xws li melting point, boiling point, ntom, solubility, xim, tsw, thiab lwm yam. yog lub cev muaj zog. Cov khoom uas piav qhia txog yuav ua li cas cov khoom hloov pauv tus kheej los tsim cov khoom tshiab yog cov khoom siv tshuaj.
