Cov nroj tsuag caustic sodakev lag luam tab tom muaj kev loj hlob tseem ceeb vim qhov kev thov nce ntxiv rau qhov tseem ceeb tshuaj lom neeg sib xyaw. Caustic soda, tseem hu ua sodium hydroxide (NaOH), ua lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem kev lag luam, tsav nws qhov kev thov thoob plaws ntau qhov chaw.
Caustic soda yog ib hom tshuaj muaj ntau yam nrog rau kev siv cov ntaub so ntswg thiab cov ntawv tsim, textiles, tshuaj tsim khoom, kev kho dej, thiab lwm yam. Hauv kev lag luam pulp thiab ntawv, nws yog siv rau pulping ntoo thiab bleaching ntawv. Hauv kev lag luam textile, nws tau ua haujlwm los ua cov ntaub thiab txhim kho lawv cov khoom. Ntxiv mus, caustic soda yog ib qho tseem ceeb hauv kev tsim khoom ntawm ntau yam tshuaj, nrog rau cov tshuaj ntxuav tes, xab npum, thiab txawm tias tshuaj.
Ib qho ntawm cov yam tseem ceeb uas ua rau muaj kev loj hlob ntawm caustic soda cog kev lag luam yog kev nthuav dav thoob ntiaj teb kev tsim toj roob hauv pes. Raws li kev lag luam loj hlob thiab kev loj hlob hauv nroog txuas ntxiv mus, qhov kev thov rau cov khoom siv tau nce ntxiv, tom qab ntawd ua rau muaj kev xav tau rau cov dej qab zib caustic hauv ntau cov txheej txheem tsim khoom.
Tsis tas li ntawd, kev kho dej tau tshwm sim los ua tus neeg siv khoom tseem ceeb ntawm cov dej qab zib caustic. Nws yog siv nyob rau hauv cov dej khib nyiab kho cov nroj tsuag rau pH hloov, coagulation, thiab neutralization. Raws li kev txhawj xeeb ib puag ncig hnyav zuj zus, cov kev cai nruj nruj tau yuam kev lag luam los nqis peev hauv kev kho cov dej khib nyiab, ntxiv rau qhov kev thov rau cov dej qab zib caustic.
Kev lag luam caustic soda cog kev lag luam kuj tseem pom kev tsim kho tshiab hauv kev tsim khoom. Cov txheej txheem niaj hnub ntawm caustic soda ntau lawm koom nrog cov txheej txheem mercury cell, uas ua rau muaj kev pheej hmoo rau ib puag ncig thiab kev noj qab haus huv. Txawm li cas los xij, kev nce qib niaj hnub no tau ua rau kev siv cov thev naus laus zis ruaj khov dua li cov txheej txheem membrane cell thiab diaphragm cell, uas muaj kev nyab xeeb dua thiab zoo ib puag ncig.
Cov neeg ua si thoob ntiaj teb hauv kev lag luam tshuaj lom neeg tau nthuav dav lawv cov peev txheej tsim khoom kom tau raws li qhov xav tau ntau ntxiv rau cov dej qab zib caustic. Qhov kev nthuav dav no tsis yog tsom rau kev ua kom tau raws li qhov xav tau tam sim no tab sis tseem xav tias yuav xav tau yav tom ntej raws li kev lag luam txuas ntxiv mus.
Hauv kev xaus,cog caustic sodakev lag luam yog nyob rau ntawm txoj kev nce siab uas tau tsav los ntawm kev xav tau ntau ntxiv rau cov tshuaj lom neeg muaj txiaj ntsig thoob plaws ntau qhov chaw. Kev lag luam muaj peev xwm hloov mus rau cov txheej txheem tsim khoom kom ruaj khov thiab nws lub luag haujlwm hauv cov ntawv thov tseem ceeb xws li kev tsim khoom thiab kev kho dej ua haujlwm nws yog ib qho tseem ceeb hauv ntiaj teb tshuaj lom neeg toj roob hauv pes.
Raws li lub ntiaj teb tau txais kev ruaj ntseg thiab kev loj hlob ntawm kev lag luam, kev lag luam caustic soda cog kev lag luam tau teeb tsa los ua lub luag haujlwm tseem ceeb hauv kev ua kom huv si, ua haujlwm zoo dua yav tom ntej.
