Hlau Complex Dyes

Cov kuab tshuaj dyes yog cov xim xim uas tsis soluble hauv dej thiab tuaj yeem yaj hauv cov kuab tshuaj organic.

Chemical structure:

        azo dyes feem ntau yog daj, txiv kab ntxwv, xim av, thiab liab, thiab tseem muaj xim liab xanthene thiab triphenylmethane dyes.Xiav thiab ntsuab feem ntau yog anthraquinone, triphenylmethane, azine, thiazine thiab phthalocyanine dyes.Nigrosin nyob rau hauv azine series yog ib qho tseem ceeb dub hnyav dye.

Muab faib ua peb series los ntawm hnyav hom, uas yog:

Solvent hom:

       Cov kuab tshuaj siv yog cawv, ethers, esters, ketones, hydrocarbons thiab chlorinated hydrocarbons, benzene hydrocarbons, thiab roj, rog, waxes thiab lwm yam.

Kev faib tawm:

(1) Insoluble hauv dej tab sis soluble hauv cawv.Cov xim ci, feem ntau yog siv rau xim cawv, hom A

(2) Cov xim tshwj xeeb rau xim xim, nws yog U hom

(3) Dyes haum rau cov xim paraffin, W hom.

Daim ntawv thov:

           Cov kuab tshuaj dyes feem ntau yog siv rau cov xim ntawm cov ntoo thiab cov yas, tab sis kuj rau cov xim pob tshab, inks, rog, roj, waxes, xab npum, roj av thiab aerosols: aluminium ntawv ci, tawv, thiab lwm yam. Nws kuj tuaj yeem siv rau xim ntawm hluavtaws pulp.

Xav paub ntau ntxiv txog hlau complex dye:

          Cov molecule muaj dyes uas sib koom tes hlau atoms.Ntxiv nrog rau acid hlau complex dyes, hlau complex disperse dyes, hlau complex nruab nrab dyes, thiab lwm yam.

Lus Cim: Qee cov dyes (direct, acidic, acidic media, cov tshuaj tiv thaiv thiab lwm yam dyes) yog complex nrog hlau ions (tooj liab, cobalt, chromium, npib tsib xee, thiab lwm yam).Soluble hauv dej.Cov khoom siv dyed yog cov resistant rau lub teeb los yog ntxhua.Piv txwv li, ncaj lub teeb-resistant turquoise xiav GL thiab acid complex xiav GGN.

         1: 2 hlau complex dye yog ib tug dye uas yog soluble nyob rau hauv organic solvents xws li aromatics, esters, styrene, methyl propionate (yuav luag insoluble nyob rau hauv dej).

     Lub ntsiab xim ntawm 1: 2 hlau complex dyes yog: daj, txiv kab ntxwv, liab, xiav, dub, thiab fluorescent liab (liab liab).

         Jiaman Qibang dej-roj-soluble kua hlau complex dye yog ib puag ncig-phooj ywg hlau complex dye hloov kho raws li cawv-soluble hlau complex dye.Nws yog cov khoom lag luam zoo tshaj plaws hauv ntiaj teb niaj hnub no.Nws tuaj yeem ua tsis tiav miscible nrog dej thaum tswj hwm ultra-siab concentration.Thaum yaj hauv dej, nws yog qhov tseeb thiab pob tshab, tsis muaj nag lossis daus thiab turbidity, thiab muaj yeeb yuj.

         Tam sim no, muaj hlau complex zas xim nrog Suav liab lub npe ntawm lub khw.Cov xim yog ci heev.Yufang Pigment tau tsim cov khoom no.Kuj hu ua chij liab.
