DSD acid (4,4 diaminostilbene mono-2,2 bisulfonic acid) chinhu chakakosha chedhayi, chinoshandiswa zvikuru kugadzira zvinopenya zve fluorescent, yero yakagwamba yakananga G, yero yakananga R, orenji F3G isingatsvedzeri zuva uye mishonga inorwisa moth-eating agents. COD iri 6000-8000mg/L, munyu uri 6%-8%, uye ruvara rwayo rwakapetwa ka50,000; zvikamu zvikuru zvemvura yakasviba makemikari e organic ane nitro, amino uye sulfonic groups, uye chiyero cheBOD neCOD i0.03 chete, izvo zvakaoma kwazvo kuora.

Hunhu hwemvura nehuwandu hwemvura yemvura yakasviba inogadzirwa neDSD acid zvakagadzikana, asi huwandu hwechromaticity nesulfate hwakakwira zvakanyanya, zvinovaka muviri zvakaita seN neP hazvipo, uye mvura yakasviba ine zvinhu zvine chepfu uye zvinokuvadza, hapana muenzaniso wekurapa unobudirira muChina. dsd acid ipureti yero kana upfu, inonyungudika muethanol ne ether, hainyungudike mumvura, inonyungudika mu alkali solution. (2) Inonyungudika nyore nyore kuita tsvuku, uye ine hunhu hwe aromatic acids ne amines panguva imwe chete.

3) Hunhu hwechigadzirwa uye indekisi yehunyanzvi: huwandu hwese hweamino (zvichienderana nehuwandu hwese hwepaste) ≥48%; huwandu hwese hweamino hwechigadzirwa chakaoma (zvichienderana nehuwandu hwese hwesamples dzekuomesa) ≥95.0%; huwandu hwese hwealkali isinganyungudike (nehuwandu hwese hwepaste) ≤0.05%; huwandu hwese hwealkali isinganyungudike (nehuwandu hwese hweupfu) ≤0.08%; benzyl matter (nehuwandu hwese hwesamples) ≤0.25% yekugadzira fluorescent whitening agent, ...

Chidimbu cheOrganic compound. Zita rakazara i4,4`-diaminostilbene-disulfonic acid. Inogona kushandiswa kugadzira fluorescent whitening agent nedzimwe dhayi. CAS Nhamba: 81-11-8 Molecular Formula：C14H14N2O6S2 Molecular Weight：370.4008 Quality Index（Specification） Chitarisiko（Chitarisiko）： light yellow powder/light yellow paste Zviri mukati（Kuchena）： ≥95. 0 Kurongedza（Pakeji）： 25 mg/kg.

0 Kurongedza (Pakeji): 25kg/40kg/bhegi Hunhu Hwemuviri Huremu hweMorekuru: 370.4, kristaro yero kana yero yakajeka ine hygroscopicity. Zviri nyore kuoxidize mumhepo. Chigadzirwa ichi chine chepfu uye chinogumbura ganda, dzivisa kusangana zvakananga nemuviri wemunhu.

Nzira yekugadzira: Nzira yekugadzira iripo ikozvino ndeye p-nitrotoluene sulfonate ne fuming sulfuric acid, yozoiswa mvura, uye NTS yakaparadzaniswa inoiswa oxidized pasi pemamiriro ealkaline nemhepo, uye DNS mu oxidation solution inoiswa munyu, yozoderedzwa ne iron powder, yozoiswa sulfuric acid. Upfu hunoomeswa uye hunoomeswa. Upfu hunotengeswa sechigadzirwa chakanyorova chekutengesa mumba, asi hunongotengeswa muchimiro cheupfu hwekutengeserana kwenyika dzese.

Kambani yeMit-ivy inonyanya kugadzira DSD ACID ine simba rekugadzira rinosvika matani chiuru nemazana mashanu pagore, uye ine musika we97%.
