Xyoo 2021 tseem yog ib xyoo uas txawv txawv heev, kev ua lag luam Calcium Chloride kuj tsis paub tseeb. Txij li thaum pib lub Rau Hli, tus nqi ntawm Calcium Chloride anhydrous, zoo li lub foob pob hluav taws, tau nce siab zuj zus. Muaj qee zaum poob qis, tab sis lawv nyob deb ntawm qhov nce nqi. Tus nqi yuav luag ob npaug ntawm cov xyoo dhau los.
Cov laj thawj tseem ceeb yog raws li nram no:
1) Tus nqi raw khoom nce siab yog qhov laj thawj tseem ceeb.
Hydrochloric acid, ua ib qho ntawm cov khoom siv raw rau kev tsim cov Calcium Chloride 95% anhydrous, tau pom nws tus nqi nce siab heev. Ncaj qha nce tus nqi tsim khoom ntawm anhydrous Calcium Chloride.
2) Kev nyuaj siab ntawm ib puag ncig
Yuav kom tiv thaiv ib puag ncig, ntau lub tuam txhab tsis ua haujlwm zoo, kev tsim khoom poob qis, thiab kev muab khoom hauv khw tsis txaus.
3) Kev thauj khoom hiav txwv nce siab
Tus nqi thauj khoom hiav txwv tseem nce siab, tsis yog siab tshaj plaws, tsuas yog siab dua xwb.
4) Ntau lub lag luam tau tso tseg lossis txo qis kev tsim khoom.
Ua ib yam khoom uas muaj nqis tsawg thiab tsis muaj txiaj ntsig ntau, yog tias qhov txiaj ntsig siab dhau los ua tsis tau raws li cov xaj, yog tias qhov txiaj ntsig qis dhau, nws yuav poob nyiaj vim tias tus nqi thauj khoom hauv hiav txwv nce siab. Cov neeg xa khoom tawm tsis txaus siab thiab cov neeg tsim khoom ua ke poob ntau dua li lawv khwv tau.
Kev kwv yees kev ua lag luam rau ib nrab xyoo thib ob ntawm xyoo 2021:Hauv kev xaus lus, tus nqi ntawm anhydrous Calcium Chloride hmoov yuav txuas ntxiv nce mus txog thaum kawg ntawm xyoo 2021.
