Daim ntawv thov thiab cov txheej txheem kev txhim kho ntawm sodium formaldehyde sulfoxylate

Sodium sulfoxylate formaldehyde (NaHSO2 · CH2O · 2H2O),

Kuj tseem hu ua assodium formaldehyde sulfoxylate,

Khoom npe: Rongalite C.

Nws yog ib tug dawb translucent thaiv nrog ib tug melting point ntawm 64 ℃. Nws muaj zog txo qis ntawm qhov kub thiab txias tuaj yeem ua rau cov ntaub dyed ploj.

Yog li ntawd, nws yog tsuas yog siv los ua tus neeg sawv cev tso tawm hauv kev lag luam luam ntawv thiab dyeing, ua cov tshuaj bleaching nyob rau hauv cov roj hmab synthesis thiab qab zib kev lag luam.

Nrog rau kev txhim kho thiab kev siv cov khoom, nyob rau hauv xyoo tas los no, nws kuj tau siv nyob rau hauv xab npum kev lag luam thiab kev kho mob raws li ib tug antidote ntawm Hg, Bi, Ba.

Kev tsim tawm ntawmrongalite feem ntau siv cov txheej txheem peb-kauj ruam, uas yog zinc hmoov-sulfur dioxide-formaldehyde txoj kev.

Ntawd yog, sulfur dioxide, zinc hmoov, thiab formaldehyde yog siv los ua raw cov ntaub ntawv, thiab sulfur dioxide thiab zinc hmoov react rau zinc dithionite (ZnS2O4), thiab tom qab ntawd formaldehyde ntxiv, zinc hmoov txo thiab sodium hydroxide metathesis cov tshuaj tiv thaiv los ua cov khoom.

Kev tsim khoom ntawm domesticrongalite kuj siv cov khoom siv tes ua saum toj no. Cov khoom lag luam yog nkag mus rau hauv kev lag luam hauv tsev, thiab qee qhov raug xa tawm mus rau South Asia.

Qhov peb nthuav qhia yog txheej txheem tshiab, uas yog, cov txheej txheem tau txais cov khoom lag luam los ntawm sodium metabisulfite ua cov khoom siv raw los ntawm kev txo cov zinc hmoov thiab ntxiv cov formaldehyde hauv ib kauj ruam.

Cov ntaub ntawv nyoos raug txo thiab ntxiv rau hauv tib lub hwj, thiab tag nrho cov reactants hloov mus rau hauv cov khoom, thiab tsis muaj pov tseg.

Ntxiv nrog rau cov khoom tseem ceeb, nws kuj tsim cov tshuaj ntshiab zinc oxide (99.5%) cov khoom.

Cov txheej txheem muaj cov yam ntxwv ntawm cov txheej txheem luv luv, cov txheej txheem ruaj khov, cov cuab yeej siv qis thiab kev ua haujlwm yooj yim.

Hauv tsab xov xwm tom ntej, kuv yuav qhia txog cov txheej txheem tsim khoom ntsig txog ntawm sodium formaldehyde sulfoxylate.
