Txhais thiab siv cov dej ntshiab
1. Txhais cov dej ntshiab
Cov dej ntshiab yog ib qho inorganic compound nrog cov tshuaj formula H2O thiab cov kua uas muaj cov qauv. Hauv cov dej ua kua, cov dej molecules tsis muaj nyob hauv ib tus neeg molecules, tab sis yog cov pawg ntawm cov dej molecules (H2O) tsim los ntawm hydrogen bonding. Yog li ntawd, kev taw qhia thiab kev txav ntawm cov dej molecules yuav cuam tshuam los ntawm lwm cov dej molecules nyob ib puag ncig.
Los ntawm txoj kev kawm, dej ntshiab yog hais txog cov dej uas muaj cov tshuaj purity siab heev, uas yog siv rau hauv thaj chaw xws li biomedicine, zaub mov thiab catering, chemical engineering, precision manufacturing, metallurgy thiab fais fab, aerospace, electronics semiconductors, thiab lwm yam. Tam sim no, cov khoom siv hluav taws xob semiconductor muaj cov kev cai nruj tshaj plaws rau cov dej ntshiab.
2. Kev siv dej ntshiab
Cov dej ntshiab yog hais txog cov dej uas tau kho kom tshem tawm impurities, minerals, thiab organic teeb meem, nrog rau purity ntau tshaj 99.9%. Cov dej ntshiab muaj ntau yam kev siv hauv lub neej txhua hnub thiab kev lag luam.
Cov dej ntshiab muaj ntau yam kev siv hauv lub neej txhua hnub. Peb xav tau dej haus txhua hnub, thiab cov dej ntshiab yog ib hom dej haus zoo tshaj plaws. Cov dej ntshiab tshem tawm feem ntau ntawm impurities thiab minerals, tiv thaiv peb lub cev noj qab haus huv. Tsis tas li ntawd, cov dej ntshiab kuj siv tau rau kev ua noj, ntxuav ntsej muag, da dej, thiab lwm yam. Hauv kev ua noj, siv cov dej ntshiab tuaj yeem ua rau cov zaub mov qab ntau dua yam tsis muaj kev cuam tshuam rau nws saj. Cov dej ntshiab huv tuaj yeem ntxuav cov tawv nqaij thiab ua kom muaj kev noj qab haus huv thaum lub ntsej muag ntxuav thiab da dej.
Cov dej ntshiab kuj muaj ntau yam kev siv hauv kev lag luam. Ntau cov txheej txheem tsim khoom lag luam yuav tsum tau siv cov dej ntshiab, xws li electronics, semiconductors, pharmaceuticals, chemicals, thiab lwm yam lag luam. Hauv kev lag luam electronics thiab semiconductor, dej ntshiab yog siv los ntxuav thiab yaug cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob semiconductor. Hauv kev lag luam tshuaj thiab tshuaj lom neeg, cov dej ntshiab yog siv los ua cov kuab tshuaj thiab cov tshuaj reactant rau cov tshuaj thiab tshuaj lom neeg. Tsis tas li ntawd, cov dej ntshiab kuj tuaj yeem siv rau kev tsim cov ntawv, luam ntawv, dyeing, txias, thiab lwm yam.
Cov dej ntshiab kuj tuaj yeem siv rau kev tiv thaiv ib puag ncig thiab kev tshawb fawb tshawb fawb. Hais txog kev tiv thaiv ib puag ncig, cov dej ntshiab tuaj yeem siv los ntxuav cov dej phwj tuaj thiab cov dej khib nyiab, txo cov dej paug. Hauv kev tshawb fawb tshawb fawb, cov dej ntshiab tuaj yeem siv rau kev tshuaj xyuas tshuaj lom neeg thiab kev sim tshuaj lom neeg hauv cov chaw soj nstuam kom paub meej qhov tseeb ntawm kev sim cov txiaj ntsig.
Cov dej ntshiab muaj ntau yam kev siv hauv ob qho tib si niaj hnub thiab kev lag luam. Nws tuaj yeem tsis tsuas yog tiv thaiv peb lub cev kev noj qab haus huv xwb, tab sis kuj txhawb kev tsim kho kev lag luam thiab kev tshawb fawb tshawb fawb.
