Nkag siab Sodium Hydrosulfide: Siv, Cia Khoom thiab Kev Nyab Xeeb
Sodium hydrosulfide, feem ntau hu uaNahs(UN 2949), yog ib qho kev sib txuas ntxiv uas muaj ntau cov ntawv thov hla kev lag luam. Muaj nyob rau hauv ntau yam kev saib xyuas, xws li 10/1/1/16, sodium hydrosulfide feem ntau, cov ntawv tseem ceeb hauv cov txheej txheem xws li kev zas xim, tshuaj dawb thiab cov ntxhia.
Ib qho ntawm cov ntsiab ntawm cov sodium hydrosulfide yog nyob rau hauv kev tsim cov sodium sulfide, tshwj xeeb yog nyob rau hauv kev tsim cov pulp thiab ntawv. Nws ua raws li tus neeg sawv cev txo, pab txhawm rau rhuav tshem lub lignin hauv ntoo, uas yog qhov tseem ceeb rau kev tsim cov ntawv zoo. Tsis tas li ntawd, hauv kev lag luam textile, sodium hydrosulfide yog siv rau nws cov khoom siv dawb, zoo tshem cov xim tsis xav tau los ntawm cov ntaub.
Nyob rau hauv cov nqe lus ntawm cia, sodium hydrosulfide yuav tsum tau daws nrog kev saib xyuas vim nws cov xwm txheej. Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, kom deb ntawm cov khoom tsis muaj peev xwm xws li cov kua qaub thiab oxidants. Cov ntim yuav tsum tau muab khi kom tiv thaiv kev nqus dej noo, xws li sodium hydrosulfide nrog dej kom tso cov roj lom hydrogen sulfide, uas ua rau muaj kev pheej hmoo txaus ntshai.
Nws yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog sodium hydrosulfide tsis ua raws li cov khoom tiv thaiv kev nyab xeeb (ppe), xws li hnab looj tes tsim nyog (PPE), xws li hnab looj tes tsim nyog (PPE), xws li hnab looj tes tsim nyog (PPE), xws li hnab looj tes tsim nyog Kev ua haujlwm ua haujlwm thiab kev kawm ua haujlwm thaum muaj xwm ceev kuj tseem ceeb rau kom ntseeg tau tias muaj kev nyab xeeb.
Hauv cov ntsiab lus, sodium hydrosulfide yog ib qho kev siv tshuaj tseem ceeb nrog ntau yam ntawm kev siv, tab sis nws yuav tsum tau ceev faj tuav thiab cia kom txo qis kev pheej hmoo. Nkag siab txog nws cov kev siv thiab kev ntsuas kev nyab xeeb yog qhov tseem ceeb rau ib tus neeg ua haujlwm nrog cov kab ke no.

kev siv
siv hauv kev lag luam tsuas yog cov inhibitor, tus neeg saib xyuas tus kheej, tshem tawm tus neeg sawv cev
Siv hauv hluavtaws organic intermediate thiab kev npaj ntawm sulphur zas additives.
Siv rau hauv textile kev lag luam raws li kev ua kom dawb huv, raws li qhov desulfurizing thiab raws li lub ntsej muag dechlorinating
siv hauv pulp thiab daim ntawv kev lag luam.
Siv hauv cov dej kho raws li cov pa oxygen tus neeg sawv cev.
Lwm Yam Siv
♦ Hauv kev lag luam yees duab los tiv thaiv cov kev daws teeb meem los ntawm oxidation.
Nws yog siv rau kev tsim cov roj hmab tshuaj thiab lwm yam kev siv tshuaj sib xyaw.
Nws siv tau rau lwm cov ntawv thov suav nrog kev muab tshuaj txhuam, roj rov qab, cov khoom noj, ua kom tuag, thiab xab npum.
