Sodium hydroxide, tseem hu ua caustic soda, yog ib qho tseem ceeb muaj tshuaj siv nyob rau hauv ntau yam kev tsim khoom. Los ntawm cov ntawv thiab textiles mus rau xab npum thiab detergents, qhov sib xyaw ua ke no ua lub luag haujlwm tseem ceeb hauv ntau yam khoom siv niaj hnub. Raws li peb saib ua ntej rau xyoo 2024, cia peb tshawb xyuas seb lub khw muaj dab tsi hauv khw rau sodium hydroxide.
Kev lag luam thoob ntiaj teb sodium hydroxide yuav tsum pom kev loj hlob tsis tu ncua nyob rau xyoo tom ntej. Raws li cov kws tshaj lij kev lag luam, qhov kev thov rau sodium hydroxide yog kwv yees kom nce ntxiv hauv ntau qhov chaw xws li cov ntaub so ntswg thiab ntawv, textiles, thiab dej kho. Nrog rau cov pej xeem nce thiab nce hauv nroog, qhov xav tau ntawm cov khoom tseem ceeb xws li ntawv thiab textiles yuav txuas ntxiv mus rau qhov kev thov rau sodium hydroxide.
Lwm qhov tseem ceeb uas ua rau muaj kev loj hlob ntawm kev lag luam sodium hydroxide yog kev nthuav dav kev lag luam. Raws li kev lag luam txuas ntxiv mus ntxiv, qhov kev thov rau sodium hydroxide ua cov khoom tseem ceeb hauv kev tsim cov xab npum, tshuaj ntxuav tes, thiab lwm yam khoom siv tu yuav nce ntxiv. Tsis tas li ntawd, kev tsim kho kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam tawm tshiab, yuav ua rau muaj kev xav tau ntau ntxiv rau sodium hydroxide hauv kev tsim khoom ntawm ntau yam khoom siv hauv tsev.
Hais txog kev thov hauv cheeb tsam, Asia-Pacific xav tias yuav yog tus neeg siv khoom loj tshaj plaws ntawm sodium hydroxide. Lub cheeb tsam kev lag luam sai thiab kev lag luam hauv nroog yog tsav kev thov rau sodium hydroxide hauv ntau daim ntawv thov. Lub caij no, North America thiab Europe tseem xav tias yuav pom kev loj hlob tsis tu ncua hauv kev lag luam sodium hydroxide vim muaj kev tsim khoom lag luam zoo.
Ntawm cov khoom siv, kev tsim cov sodium hydroxide yuav tsum nce thoob ntiaj teb kom tau raws li qhov xav tau nce. Cov tuam txhab lag luam loj tau tsom mus rau kev nthuav dav lawv cov peev txheej ntau lawm kom ua tau raws li qhov xav tau ntawm ntau yam kev lag luam. Qhov muaj peev xwm ntau lawm no kuj tseem yuav ua rau kev txhim kho cov saw hlau txuas ntxiv, ua rau sodium hydroxide yooj yim dua rau cov neeg siv khoom.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tau xav txog cov teeb meem uas yuav cuam tshuam rau kev lag luam sodium hydroxide nyob rau xyoo tom ntej. Ib qho zoo li no yog qhov hloov pauv ntawm cov khoom siv raw, tshwj xeeb tshaj yog tus nqi ntawm electrolysis-qib ntsev, uas yog ib qho tseem ceeb hauv kev tsim cov sodium hydroxide. Tsis tas li ntawd, kev tswj hwm ib puag ncig nruj thiab nce kev tsom mus rau cov txheej txheem tsim khoom kom ruaj khov kuj tseem yuav ua rau muaj teeb meem rau cov tuam txhab.
Saib ua ntej rau xyoo 2024, kev lag luam sodium hydroxide tau npaj rau kev loj hlob, tau tsav los ntawm kev xav tau los ntawm ntau yam kev lag luam siv kawg. Raws li kev lag luam thoob ntiaj teb txuas ntxiv txhim kho thiab nthuav dav, qhov tseem ceeb ntawm sodium hydroxide yog ib qho tseem ceeb ntawm kev lag luam tshuaj yuav tsuas yog ua kom pom tseeb. Nrog rau cov tswv yim zoo nyob rau hauv qhov chaw los daws cov teeb meem muaj peev xwm, kev lag luam sodium hydroxide yog qhov chaw zoo rau lub neej yav tom ntej.
