DSD acid (4,4 diaminostilbene mono-2,2 bisulfonic acid) yog ib qho tseem ceeb ntawm cov xim nruab nrab, feem ntau yog siv los tsim cov tshuaj fluorescent brighteners, ncaj qha khov daj G, ncaj qha daj R, hnub ci-resistant txiv kab ntxwv F3G thiab cov neeg sawv cev tiv thaiv kab npauj npaim. COD yog 6000-8000mg / L, salinity yog 6% -8%, thiab xim yog 50,000 zaug; cov khoom tseem ceeb ntawm cov dej khib nyiab yog cov organic sib xyaw aromatic nrog nitro, amino thiab sulfonic pawg, thiab qhov piv ntawm BOD rau COD tsuas yog 0.03, uas nyuaj heev rau biodegrade.

Qhov zoo ntawm dej thiab cov dej ntawm DSD acid cov dej khib nyiab yog ruaj khov, tab sis qhov chromaticity thiab sulfate concentration siab heev, cov as-ham xws li N thiab P tsis txaus, thiab cov dej khib nyiab muaj cov tshuaj lom thiab cov tshuaj lom, tsis muaj piv txwv kev kho mob zoo hauv Suav teb. dsd acid yog ib qho daj daj lossis hmoov, soluble hauv ethanol thiab ether, insoluble hauv dej, soluble hauv alkali kua. (2) Nws yooj yim oxidized rau liab, thiab muaj cov khoom ntawm aromatic acids thiab amines tib lub sijhawm.

3) Cov khoom zoo thiab cov ntsuas kev ua haujlwm: tag nrho cov amino nqi (raws li tag nrho cov nyiaj ntawm cov tshuaj nplaum) ≥48%; cov khoom qhuav tag nrho cov amino nqi (raws li tag nrho cov nyiaj ntawm cov qauv ziab) ≥95.0%; alkali insoluble teeb meem cov ntsiab lus (los ntawm tag nrho cov nyiaj ntawm cov tshuaj nplaum) ≤0.05%; alkali insoluble teeb meem cov ntsiab lus (los ntawm tag nrho cov nyiaj ntawm cov hmoov) ≤0.08%; benzyl teeb meem (los ntawm tag nrho cov nyiaj ntawm cov qauv) ≤0.25% rau kev tsim cov tshuaj dawb fluorescent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent, fluorescent whitening agent. Ncaj qha khov daj G thiab ncaj qha daj R, thiab siv ua tshuaj tua kab.

Cov tshuaj organic luv luv. Lub npe tag nrho yog 4,4`-diaminostilbene-disulfonic acid. Nws tuaj yeem siv rau kev tsim cov tshuaj dawb fluorescent thiab lwm yam xim. CAS No.: 81-11-8 Cov mis molecular: C14H14N2O6S2 Qhov hnyav molecular: 370.4008 Cov ntsuas zoo (Kev qhia tshwj xeeb) Tsos (Zoo li): hmoov daj daj / nplaum daj daj Cov ntsiab lus (Purity): ≥95. 0 Ntim (Pob): 25 mg / kg.

0 Ntim (Pob): 25kg/40kg/hnab Cov Khoom Siv Lub Cev Lub Cev Qhov Hnyav Molecular: 370.4, siv lead ua daj lossis daj daj nrog hygroscopicity. Nws yooj yim rau oxidize hauv huab cua. Cov khoom no yog lom thiab khaus rau daim tawv nqaij, tsis txhob kov ncaj qha rau tib neeg lub cev.

Txoj kev tsim cov tshuaj: Txoj kev tsim cov tshuaj tam sim no yog p-nitrotoluene sulfonated nrog fuming sulfuric acid, tom qab ntawd precipitated nrog dej, thiab NTS sib cais yog oxidized nyob rau hauv alkaline mob nrog huab cua, thiab DNS nyob rau hauv cov tshuaj oxidation yog precipitated nrog ntsev, tom qab ntawd txo nrog hlau hmoov, thiab tom qab ntawd precipitated nrog sulfuric acid. Cov hmoov yog qhuav thiab qhuav. Cov hmoov yog muag ua cov khoom ntub rau kev muag khoom hauv tsev, tab sis tsuas yog muag hauv daim ntawv hmoov rau kev lag luam thoob ntiaj teb.

Lub tuam txhab kev lag luam Mit-ivy feem ntau tsim cov DSD ACID nrog lub peev xwm tsim khoom txhua xyoo ntawm 1,000,000 tons, thiab muaj feem lag luam ntawm 97%.
