Nws yog tsuas yog siv los ua tus stabilizer rau hluavtaws fibers, bleaching tus neeg sawv cev rau fabrics, ib tug yees duab tsim, deoxidizer rau dyeing thiab bleaching, txo tus neeg sawv cev rau fragrances thiab dyes, thiab lignin tshem tawm tus neeg sawv cev nyob rau hauv papermaking.
Hauv kev kho dej, sodium sulfite yog siv los ua deoxidizer rau boiler dej thiab oilfield txhaj dej, thiab ib tug dechlorinator rau lub nroog los yog industrial dej. Hauv kev kho dej khib nyiab, nws yog siv los txo cov hexavalent chromium ntsev kom tsawg - lom trivalent chromium ntsev, thiab tuaj yeem ua rau nag thiab cais cov nyiaj thiab mercury ntawm cov dej khib nyiab. Sulfite yog dav siv nyob rau hauv me me thiab nruab nrab- boilers loj thiab boilers ua hauj lwm nyob rau hauv siab qis dua 5.88 MPa, feem ntau npaj raws li ib tug 2% -10% tov. Cov koob tshuaj ib txwm siv ntawm sodium sulfite yog 0.076 g / L. Nws yog qhov zoo tshaj plaws los ntxiv qhov tsim nyog ntawm catalyst, xws li ntsev ntawm Cu, Co, Mn, thiab Ni, los txhim kho deoxygenation tus nqi. Thaum tsis siv lub boiler, nws tuaj yeem ntim nrog alkaline deoxygenated dej uas muaj kwv yees li 200 mg / L sodium sulfite los tiv thaiv cov hlau los ntawm corrosion. Thaum tshem tawm cov tshuaj dawb dawb los ntawm dej, sodium sulfite yuav tsum tau siv ua ke nrog sodium bisulfite lossis sulfur dioxide. Tsis tas li ntawd, raws li ib tug deoxidizer rau cov dej txhaj tshuaj nyob rau hauv oilfield ntau lawm, ntxiv 10 mg / L ntawm sodium sulfite tuaj yeem tswj cov pa oxygen corrosion ntawm lub qhov dej zoo. Tsis tas li ntawd, sodium sulfite yog siv rau hauv kev tsim tshuaj raws li cov khoom siv raw rau sodium thiosulfate ntau lawm, thiab tseem yog ib qho stabilizer rau viscose fibers, tshuaj tua kab mob rau npias fwj, ib tug engraving tus neeg saib xyuas rau iav tsom iav thiab slates, bleaching tivthaiv thiab deoxidizer rau fabrics, thiab tus tsim tawm rau lub photosensitive kev lag luam.
