Sulphur, chlorine thiab fluorine tsis yog hlau. … Yog li, nws muaj tag nrho cov khoom ntawm cov hlau uas txhais tau tias nws tuaj yeem raug ntaus rau hauv cov ntawv nyias heev. Nws yog malleable nyob rau hauv qhov. Yog li ntawd, kev xaiv, 'B.
Puas Sulfur tuaj yeem raug ntaus ua cov ntawv nyias?
Tawm ntawm qhov no, cov hlau tuaj yeem kos rau hauv cov ntawv nyias thiab cov cuab yeej los ntawm cov hlau tuaj yeem raug ntaus rau hauv cov ntawv nyias yam tsis muaj qhov tawg yog hu ua malleability. Tag nrho cov hlau yog malleable nrog qee qhov kev zam. Yog li, tib lub hlau peb muaj nyob rau hauv peb lo lus nug yog zinc, thiab yog li qhov kev xaiv raug yog A.
Yuav ua li cas thiaj ntaus tau rau hauv daim ntawv?
Piv txwv ntawm cov hlau uas tuaj yeem ua tau yog kub, hlau, txhuas, tooj liab, nyiaj, thiab txhuas. Ntawm tag nrho cov ntsiab lus nyob rau hauv lub sij hawm lub sij hawm magnesium (Mg) muaj qis tshaj malleability. Yog li ntawd lo lus teb yuav yog zinc vim nws yog cov hlau uas tuaj yeem raug ntaus ua cov ntawv yooj yim.
Cov ntsiab lus twg tsis tuaj yeem raug ntaus rau hauv nplooj ntawv?
Kev piav qhia: Zinc yog tib lub hlau uas tuaj yeem ua kom nyias nyias. Zinc muaj cov khoom zoo tshaj plaws thaum lwm cov khoom tsis yog hlau uas tsis yog-malleable yog li tsis tuaj yeem raug ntaus rau hauv cov ntawv.
Cov pob zeb twg tuaj yeem raug ntaus ua cov ntawv?
Mica yog cov ntxhia tsis yog xim hlau uas tuaj yeem faib tau yooj yim rau hauv cov ntawv nyias. Mica siv nyob rau hauv: (i) Hluav taws xob thiab hluav taws xob kev lag luam: Mica yog siv nyob rau hauv cov industries vim nws zoo heevLub zog dielectric, tsis tshua muaj hluav taws xob tsis zoo, cov khoom siv hluav taws xob thiab ua haujlwm rau high voltage.
