I-DSD acid (4,4 diaminostilbene mono-2,2 bisulfonic acid) iwudayi obalulekile omaphakathi, ikakhulukazi osetshenziselwa ukwenza izikhanyisi ze-fluorescent, eziphuzi eziqondile eziqandisiwe G, u-R ophuzi oqondile, owolintshi ongazweli e-F3G kanye nama-anti-moth-eating agents. I-COD ingu-6000-8000mg/L, usawoti ngu-6% -8%, nombala izikhathi ezingu-50,000; izingxenye eziyinhloko zamanzi angcolile ziyinhlanganisela ye-organic enamakha ane-nitro, amino kanye namaqembu e-sulfonic, kanti isilinganiso se-BOD ne-COD singu-0.03 kuphela, okunzima kakhulu ukubola.

Izinga lamanzi nenani lamanzi okukhiqizwa kwe-asidi ye-DSD lamanzi angcolile lizinzile, kodwa i-chromaticity ne-sulfate concentration iphezulu kakhulu, imisoco efana ne-N no-P ayinakho, futhi amanzi angcolile aqukethe izinto ezinobuthi neziyingozi, asikho isibonelo sokwelashwa okuphumelelayo China. I-dsd acid inhlama ephuzi noma impushana ekhanyayo, encibilika ku-ethanol ne-ether, engancibiliki emanzini, encibilika kusixazululo se-alkali. (2) I-oxidized kalula ibe bomvu, futhi inezakhiwo zama-asidi anephunga elimnandi nama-amine ngesikhathi esifanayo.

3) Ikhwalithi yomkhiqizo kanye nenkomba yezobuchwepheshe: inani le-amino eliphelele (ngokwenani eliphelele lokunamathisela) ≥48%; umkhiqizo owomile inani le-amino eliphelele (ngokwenani eliphelele lamasampuli okomisa) ≥95.0%; okuqukethwe kwe-alkali engancibiliki (ngenani eliphelele lokunamathisela) ≤0.05%; okuqukethwe kwe-alkali engancibiliki (ngenani eliphelele lempushana) ≤0.08%; i-benzyl matter (ngenani eliphelele lamasampuli) ≤0.25% ukuze kukhiqizwe i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti ekhanyayo ye-fluorescent i-ejenti emhlophe, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent, i-ejenti emhlophe ye-fluorescent emhlophe, i-fluorescent whitening agent Okuphuzi okuqondile okuqandisiwe okuqondile no-R okuphuzi okuqondile, futhi kusetshenziswe njengesibulala-zinambuzane.

Isifinyezo senhlanganisela ye-Organic. Igama eligcwele yi-4,4`-diaminostilbene-disulfonic acid. Ingasetshenziselwa ukuhlanganiswa kwe-agent emhlophe ye-fluorescent kanye nabanye odayi. Inombolo ye-CAS: 81-11-8 I-Molecular Formula:C14H14N2O6S2 Isisindo Se-Molecular:370.4008 Quality Index (Ukucaciswa) Ukubukeka (Ukubukeka): Impushana ephuzi ekhanyayo/Okuqukethwe kokunamathisela okuphuzi okukhanyayo (Ubumsulwa): ≥95. 0 Ukupakisha (Iphakheji): 25 mg/kg.

0 Ukupakisha (Iphakheji): 25kg/40kg/isikhwama Izakhiwo Zomzimba Isisindo Semolekyuli: 370.4, ikristalu ephuzi noma ekhanyayo ephuzi ene-hygroscopicity. Kulula ukufaka i-oxidize emoyeni. Lo mkhiqizo unobuthi futhi uyacasula esikhumbeni, gwema ukuthintana ngqo nomzimba womuntu.

Indlela yokuhlanganisa: Indlela yamanje yokuhlanganisa i-p-nitrotoluene sulfonated ne-fuming sulfuric acid, bese iwa ngamanzi, bese i-NTS ehlukanisiwe ifakwe i-oxidized ngaphansi kwezimo ze-alkaline ngomoya, kanti i-DNS esixazululweni se-oxidation iqalwa ngosawoti, bese incishiswa ngensimbi. impushana, bese igcwaliswa nge-sulfuric acid. Impushana yomile futhi yomisiwe. Impushana idayiswa njengomkhiqizo omanzi ukuze ithengiswe ekhaya, kodwa idayiswa kuphela iyimpushana ukuze kuhwetshwe ngayo amazwe ngamazwe.

Inkampani yemboni ye-Mit-ivy ikhiqiza ikakhulukazi i-DSD ACID enamandla okukhiqiza minyaka yonke amathani ayi-1,000,000, futhi inesabelo semakethe esiphelele esingu-97%.
