Thoob Ntiaj Teb - Qib Siab Sodium Sulfide: Cov Tshuaj Tseem Ceeb Rau Ntau Yam Kev Lag Luam
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam ntawv, peb cov sodium sulfide ua lub luag haujlwm tseem ceeb hauv cov txheej txheem kraft pulping. Nws pab rhuav tshem lignin, ib qho polymer organic uas khi cellulose fibers hauv ntoo. Los ntawm kev yaj lignin, sodium sulfide ua rau muaj kev sib cais ntawm cellulose, uas yog cov khoom tseem ceeb siv los ua ntawv. Qhov no ua rau cov pulp zoo dua nrog lub zog thiab ci ntsa iab dua. Cov chaw tsim ntawv tuaj yeem tsim ntau yam khoom ntawv, los ntawm cov ntawv xov xwm mus rau cov ntawv luam ntawv siab, siv peb cov sodium sulfide los txhim kho lawv cov txiaj ntsig zoo thiab cov khoom zoo.
Kev lag luam textile kuj tau txais txiaj ntsig zoo los ntawm peb lub Global - Premier Sodium Sulfide. Nws yog siv rau hauv cov txheej txheem desulfurization ntawm cov ntaub plaub. Cov ntaub plaub feem ntau muaj cov tshuaj sulfur uas tuaj yeem cuam tshuam rau nws qhov zoo thiab kev ua tiav. Sodium sulfide reacts nrog cov tshuaj no, tshem tawm sulfur thiab txhim kho qhov mos, xim, thiab qhov zoo ntawm cov ntaub plaub. Tsis tas li ntawd, nws yog siv rau hauv qee cov txheej txheem dyeing los kho qhov chaw ib puag ncig tshuaj, pab txhawb kev nqus xim zoo dua los ntawm cov ntaub, ua rau muaj xim ci ntsa iab thiab ntev dua.
Hauv kev lag luam mining, sodium sulfide yog ib qho tseem ceeb reagent. Nws yog siv rau hauv cov txheej txheem flotation ntawm qee cov hlau ores, tshwj xeeb tshaj yog cov uas muaj tooj liab, txhuas, thiab zinc. Sodium sulfide tuaj yeem ua kom cov nplaim ntawm cov ores no ua haujlwm, ua rau lawv txais tos ntau dua rau cov neeg sawv cev siv hauv flotation. Qhov no txhim kho qhov ua tau zoo ntawm kev sib cais cov zaub mov muaj nqis ntawm gangue (pob zeb pov tseg), ua rau kom rov qab tau cov hlau muaj nqis. Cov tuam txhab mining vam khom peb cov sodium sulfide los ua kom zoo dua lawv cov haujlwm ua ore thiab ua kom lawv cov nyiaj tau los ntau tshaj plaws.
Hauv kev lag luam tawv, peb cov sodium sulfide siv rau hauv cov txheej txheem tshem cov plaub hau. Nws pab yaj cov protein hauv cov plaub hau thiab epidermis ntawm cov tawv tsiaj, ua rau nws yooj yim dua rau kev tshem tawm cov plaub hau. Qhov no yog ib kauj ruam tseem ceeb hauv kev tsim tawv vim nws npaj cov tawv rau kev ua tiav ntxiv. Los ntawm kev siv peb cov sodium sulfide zoo, cov chaw tsim khoom tawv tuaj yeem tsim cov tawv nrog qhov chaw du thiab cov qauv zoo dua, ua tau raws li cov qauv siab ntawm kev lag luam tawv thoob ntiaj teb.
