Thoob Ntiaj Teb - Premier Sodium Sulfite: Cov Tshuaj Tseem Ceeb rau Kev Siv Hauv Kev Lag Luam Ntau Yam
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam ntawv, sodium sulfite ua lub luag haujlwm tseem ceeb. Nws yog siv rau hauv cov txheej txheem pulping los rhuav tshem lignin, ib qho polymer nyuaj uas khi cellulose fibers hauv ntoo. Los ntawm kev cuam tshuam nrog lignin, sodium sulfite pab yaj nws, cais cov cellulose fibers thiab ua rau lawv muaj rau kev ua ntawv. Qhov no ua rau cov pulp zoo dua nrog lub zog thiab ci ntsa iab zoo dua. Cov chaw tsim ntawv vam khom peb cov sodium sulfite los tsim ntau yam khoom ntawv, los ntawm cov ntawv xov xwm mus rau cov ntawv luam ntawv siab, nrog kev ua tau zoo dua thiab zoo nkauj.
Kev lag luam textile kuj tau txais txiaj ntsig zoo los ntawm peb lub Global - Premier Sodium Sulfite. Nws yog siv ua tus neeg sawv cev txo qis hauv cov txheej txheem dyeing thiab ua tiav cov ntaub. Hauv kev dyeing, sodium sulfite pab hloov qee cov xim rau hauv lawv cov qauv soluble, cia lawv nkag mus rau hauv cov ntaub fibers zoo dua. Qhov no ua rau muaj xim ci ntsa iab thiab ntev dua. Tsis tas li ntawd, nws tuaj yeem siv los tshem tawm cov xim ntau dhau thiab cov neeg sawv cev oxidizing ntawm cov ntaub, txhim kho qhov zoo ntawm cov khoom tiav. Cov chaw tsim khoom siv textile siv peb cov sodium sulfite los tsim cov ntaub zoo uas ua tau raws li qhov xav tau ntawm kev lag luam zam thiab kho kom zoo nkauj hauv tsev.
Hauv kev lag luam khoom noj, sodium sulfite ua haujlwm ua cov tshuaj preservative thiab antioxidant. Nws pab tiv thaiv kev oxidation ntawm cov khoom noj, xws li cov rog thiab roj, uas tuaj yeem ua rau rancid thiab spoilage. Nws kuj tseem tiv thaiv kev loj hlob ntawm cov kab mob me me, ua rau lub txee ntev ntawm cov khoom noj. Piv txwv li, hauv cov txiv hmab txiv ntoo qhuav thiab zaub, sodium sulfite pab tswj lawv cov xim, saj, thiab cov khoom noj muaj txiaj ntsig. Cov chaw tsim khoom noj vam khom peb cov sodium sulfite los xyuas kom meej tias lawv cov khoom muaj kev nyab xeeb thiab zoo, thaum tseem ua raws li cov cai tswjfwm kev nyab xeeb khoom noj nruj.
Hauv kev lag luam kho dej, sodium sulfite yog siv los ua cov tshuaj oxygen scavenger. Cov pa oxygen uas yaj hauv dej tuaj yeem ua rau xeb hauv cov kav dej, boilers, thiab lwm yam khoom siv hauv kev lag luam. Sodium sulfite reacts nrog oxygen los tsim sodium sulfate, tshem tawm cov pa oxygen thiab tiv thaiv kev xeb. Cov chaw kho dej thiab cov chaw lag luam siv peb cov sodium sulfite los tiv thaiv lawv cov khoom siv, txo cov nqi kho, thiab xyuas kom meej tias lawv cov kab ke ua haujlwm zoo.
