Kuaj Dub 27

· CI Index No.: CI Solvent Black 27

· CAS No.: [3861-74-1] / [12237-22-8] (tej zaum yuav txawv ntawm isomer lossis ntsev daim ntawv)

· Chemical Class: Anthraquinone-raws li hnyav dye

· Cov tsos mob: feem ntau yog xiav tsaus rau cov hmoov dub los yog khoom.

Qauv & Khoom

· Structure: Nws yog ib tug derivative ntawm 1-amino-4-arylaminoanthraquinone chav kawm. Nws cov qauv molecular muaj cov anthraquinone chromophore, nrog rau cov khoom siv tshwj xeeb (xws li arylamino pawg) uas kho nws cov solubility hauv cov kuab tshuaj organic thiab nws cov ntxoov ntxoo.

· Solubility: Insoluble nyob rau hauv dej, tab sis yooj yim soluble nyob rau hauv ib tug ntau yam ntawm cov organic solvents, xws li:

· Aromatic hydrocarbons (benzene, toluene, xylene)

· Halogenated hydrocarbons (chloroform, dichloromethane)

· Ketones (acetone, methyl ethyl ketone)

· Esters

· Qee yam cawv thiab roj ntau dua.

· Ntxoov ntxoo: Imparts xiav -dub mus rau dub xim nyob rau hauv kev daws.

Cov ntawv thov tseem ceeb

Vim nws cov kuab tshuaj zoo heev solubility thiab stability, Solvent Black 27 feem ntau yog siv rau cov xim uas tsis yog -aqueous systems:

1. Plastics Coloring: Tshwj xeeb yog tsim rau colouring polystyrene (PS), polymethyl methacrylate (PMMA/acrylic), polycarbonate (PC), thiab lwm yam engineering plastics. Nws muab qhov sib sib zog nqus, pob tshab dub ntxoov ntxoo.

2. Ink Industry: Siv nyob rau hauv kev tsim ntau yam hnyav-raws li inks, xws li gravure printing inks, flexographic printing inks, thiab hlau kho kom zoo nkauj inks.

3. Resins & Coatings: Siv rau xim lacquers, resin khoom, thiab lwm yam ntaub ntawv txheej uas yuav tsum tau dissolution nyob rau hauv cov organic solvents.

4. Lwm tus: Kuj tseem siv rau xim waxes, greases, khau polishes, thiab lwm yam.

Kev nyab xeeb & kev tswj hwm xwm txheej

· Toxicity: Raws li ib qho tshuaj, kev nqus plua plav thiab kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav tsum zam. Cov ntaub ntawv tshwj xeeb toxicity yuav tsum tau sab laj los ntawm nws Daim Ntawv Qhia Kev Nyab Xeeb (SDS).

· Ib puag ncig: Nws tsis yooj yim biodegradable thiab tej zaum yuav lom rau cov kab mob hauv dej. Kev siv thiab pov tseg yuav tsum ua raws li cov cai hauv cheeb tsam ib puag ncig.

· Regulatory Status: Nws tsis yog ib qho ntawm cov classic "banned azo dyes" (cov uas cleave tso tawm carcinogenic aromatic amines). Txawm li cas los xij, nws cov kev tsim khoom thiab kev siv yuav tsum ua raws li kev tswj hwm tshuaj lom neeg xws li EU REACH txoj cai. Tej zaum yuav muaj kev txwv rau kev siv tshwj xeeb lossis hauv qee thaj tsam.

Kev sib txawv ntawm cov khoom zoo sib xws

· vs. Solvent Black 7: Solvent Black 7 (CI Solvent Black 7) feem ntau yog ib qho azo-raws li hnyav hnyav dye, whereas Solvent Black 27 yog anthraquinone-raws li. Anthraquinone dyes feem ntau muab lub teeb zoo dua thiab kub ceev tab sis ntawm tus nqi siab dua.

· vs. Carbon Black: Cov roj carbon dub yog cov xim tsis muaj zog, xim los ntawm lub cev dispersion. Nws feem ntau yog opaque thiab conductive. Solvent Black 27 yog cov organic dye uas yaj ntawm qib molecular, muab cov xim dub pob tshab los yog translucent thiab tsis yog -conductive.

Cov ntsiab lus

Solvent Black 27 yog ib qho kev ua haujlwm siab -kev ua tau zoo, anthraquinone-raws li cov kuab tshuaj dub, muaj nuj nqis rau nws qhov zoo tshaj plaws lightfastness, kub tsis kam, solubility, thiab transparency. Nws thawj daim ntawv thov yog nyob rau hauv siab- cov yas zoo (xws li, PS, PMMA) thiab cov kuab tshuaj-raws li inks, qhov xav tau xim kev ua tau zoo thiab ruaj khov. Kev tswj hwm kev nyab xeeb thiab kev tswj hwm ib puag ncig yuav tsum tau saib xyuas thaum siv.
