Malleability txhais tau tias hlau tuaj yeem ua rau cov ntawv thiab cov ntawv. Piv txwv li, aluminium foils yog siv los qhwv cov khoom noj khoom haus, nyiaj foils yog siv los kho cov khoom qab zib thiab txiv hmab txiv ntoo. Ductility txhais tau hais tias cov hlau tuaj yeem kos rau hauv cov xov hlau. Kub thiab nyiaj xov hlau yog siv rau hauv ornaments.
muag khoom siv tau qhov twg?
Thaum cov hlau zoo li tooj liab, tin, txhuas, thiab hlau yog cov khoom siv los yog cov khoom siv, lawv yuav luag zoo li khob noom cookie. Uas ua rau nws yooj yim rau cov tuam txhab tsim khoom kom yob lawv tawm, yuam lawv los ntawm cov tshuab sib txawv, thiab tseem coj lawv rov qab mus rau lawv lub xeev qub zoo li khob noom cookie.
Yuav ua li cas thiaj siv tau hauv lub neej txhua hnub?
a) Cov ntim khoom siv hauv chav ua noj yog ua los ntawm cov hlau uas tau kos rau hauv qhov xav tau zoo li cov hlau yog malleable. b) Hlau siv los ua ornaments xws li kub thiab nyiaj yog thawj kos rau hauv cov duab ntawm lub caj dab, rings thiab lwm yam no tsuas yog ua tau vim hlau yog malleable.
Ib qho piv txwv zoo ntawm kev ua tau zoo yog dab tsi?
Cov cuab yeej hlau uas tuaj yeem raug ntaus rau hauv cov ntawv nyias, ces cov cuab yeej hu ua malleability. Cov cuab yeej no tau pom los ntawm cov hlau uas tuaj yeem kos rau hauv cov nplooj ntawv thaum hammered. Piv txwv li: steel, aluminium, tooj liab, nyiaj, txhuas thiab lwm yam.
Cov khoom siv tuaj yeem siv tau li cas?
Malleable khoom tuaj yeem hloov pauv mus rau hauv cov duab sib txawv thiab ntau thiab tsawg, thiab lawv cov khoomtuaj yeem hloov pauv (piv txwv li los ntawm kev ntxiv dej). Ua si nrog cov ntaub ntawv malleable muab kev xav txog cov duab, qhov chaw thiab cheeb tsam - thiab cov hauv paus ntawm chemistry.
