Asidi wa DSD (4,4 diaminostilbene mono-2,2 bisulfonic acid) ndi wofunika kwambiri wa utoto wapakatikati, womwe umagwiritsidwa ntchito kwambiri popanga zowunikira za fulorosenti, zachikasu zowongoka zamtundu wa G, chikasu cholunjika cha R, malalanje osamva kuwala kwa dzuwa F3G ndi anti-moth-eating agents. COD ndi 6000-8000mg/L, mchere ndi 6% -8%, ndipo mtundu ndi nthawi 50,000; zigawo zikuluzikulu za madzi oipa ndi zonunkhira organic mankhwala ndi nitro, amino ndi sulfonic magulu, ndi chiŵerengero cha BOD kwa COD ndi 0,03 yekha, amene ndi zovuta kwambiri biodegrade.

Mlingo wamadzi ndi kuchuluka kwa madzi amadzi onyansa a DSD acid ndi okhazikika, koma chromaticity ndi sulphate ndende ndizokwera kwambiri, zakudya monga N ndi P zikusowa, ndipo madzi otayira amakhala ndi zinthu zoopsa komanso zovulaza, palibe chitsanzo chabwino chamankhwala. China. dsd acid ndi phala lachikasu lopepuka kapena ufa, wosungunuka mu ethanol ndi ether, wosasungunuka m'madzi, sungunuka mu njira ya alkali. (2) Imakhala ndi okosijeni mosavuta kufiira, ndipo imakhala ndi ma asidi onunkhira ndi ma amines nthawi yomweyo.

3) Ubwino wazinthu ndi index yaukadaulo: mtengo wonse wa amino (malinga ndi kuchuluka kwa phala) ≥48%; mankhwala owuma okwana mtengo wa amino (malinga ndi kuchuluka kwa zitsanzo zowuma) ≥95.0%; zinthu za alkali zosasungunuka (ndi kuchuluka kwa phala) ≤0.05%; zinthu za alkali zosasungunuka (ndi kuchuluka kwa ufa) ≤0.08%; benzyl nkhani (ndi kuchuluka kwa zitsanzo) ≤0.25% kwa kupanga fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti, fulorosenti whitening agent whitening wothandizira, fulorosenti whitening wothandizira, fulorosenti whitening wothandizira, fulorosenti whitening wothandizira, fulorosenti whitening wothandizira, fulorosenti whitening wothandizira, fulorosenti whitening wothandizila, fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti whitening, fulorosenti whitening wothandizila fulorosenti whitening wothandizila fulorosenti. Yeloni wozizira kwambiri wa G ndi wachikasu R, ndipo amagwiritsidwa ntchito ngati mankhwala ophera tizilombo.

Organic pawiri chidule. Dzina lonse ndi 4,4`-diaminostilbene-disulfonic acid. Itha kugwiritsidwa ntchito popanga ma fulorosenti whitening wothandizira ndi utoto wina. CAS No.: 81-11-8 Molecular Formula:C14H14N2O6S2 Molecular Weight:370.4008 Quality Index (Mawonekedwe) Maonekedwe (Maonekedwe): kuwala chikasu ufa / kuwala yellow phala Zokhutira (Kuyera): ≥95. 0 Kulongedza (Phukusi): 25 mg / kg.

0 Kulongedza (Phukusi): 25kg / 40kg / thumba Physical Properties Kulemera kwa maselo: 370.4, kristalo wachikasu kapena wowala wachikasu ndi hygroscopicity. N'zosavuta kuti oxidize mu mpweya. Mankhwalawa ndi oopsa komanso amakwiyitsa khungu, pewani kukhudzana mwachindunji ndi thupi la munthu.

Kaphatikizidwe njira: panopa kaphatikizidwe njira ndi p-nitrotoluene sulfonated ndi fuming sulfuric acid, ndiye precipitated ndi madzi, ndi olekanitsidwa NTS ndi oxidized pansi zinthu zamchere ndi mpweya, ndi DNS mu makutidwe ndi okosijeni njira precipitated ndi mchere, ndiye kuchepetsedwa ndi chitsulo. ufa, ndiyeno umatenthedwa ndi sulfuric acid. ufa ndi zouma ndi zouma. Ufawu umagulitsidwa ngati chinthu chonyowa pazogulitsa zapakhomo, koma umangogulitsidwa ngati ufa pamalonda apadziko lonse lapansi.

Kampani yamakampani a Mit-ivy imapanga makamaka DSD ACID yokhala ndi mphamvu yopanga pachaka ya matani 1,000,000, ndipo ili ndi gawo lokwanira la msika la 97%.
