CAS Nr .: 68123-13-7 BASIC BLUE 99

Txauv peev xwm hais txog tus nqi ntawm ions uas ib chav tsev loj lossis ntim ntawm cov resin pauv tau. Nws yog qhov taw qhia tseem ceeb rau kev ntsuas kev sib pauv peev xwm ntawm cov resin.

1. Textile dyeing thiab luam ntawv: Cationic reactive dyes rau paj rwb / linen / viscose fibers
2. Kev kuaj biochemical: Redox enzymes / Hydrogen peroxide colorimetric substrate
3. Ntawv Kev Lag Luam: Cationic Colorants rau Cultural Paper / Ntim Ntawv
4. Lwm daim ntawv thov (organic photoelectric coloration material intermediates / anti-cov ntaub ntawv pov thawj ink raw khoom / dej ntsuas ntsuas qhov zoo)

1. Lub electrostatic adsorption ntawm cationic dyes daws cov teeb meem ntawm qeeb dyeing, tsawg siv tus nqi, thiab tsis sib xws dyeing nyob rau hauv cov tsoos anionic dyes, ua tau zoo thiab uniform dye accumulation;
2. Covalent bonding ntawm anionic dyes daws cov teeb meem ntawm kev ceev ceev tsis zoo, yooj yim fading, thiab cov xim tsis zoo nyob rau hauv cov tshuaj cationic dyes, ua tiav ntev - kav ntev thiab ruaj khov dye fixation.

Lub zog sib txuas nrog cov tub ntxhais ntawm cov tawv nqaij fibers yog cov electrostatic attraction (ion bond) ntawm cov quaternary ammonium ntsev cations thiab cov anions ntawm cov pulp fibers. Nyob rau tib lub sijhawm, nws tau txais kev txhawb nqa los ntawm van der Waals rog, hydrophobic kev sib cuam tshuam, thiab kev taw qhia thiab ntom ntom ntawm cov qauv molecular nruj ntxiv ntxiv dag zog rau kev khi lub zog. Nws txoj hlua khi muaj zog ntau dua li qhov sib txuas ntawm lub cev ntawm cov nplaum thiab tuaj yeem ua tiav qhov ruaj khov hauv cov txheej txheem dej papermaking.

This compound requires sealing and protection from light in a 0-25℃ environment for storage in its solid state. The core issue is that the naphthoquinone imine chromogenic subunit is a weak point in its structure. Exposure to light (especially ultraviolet light) will cause irreversible photochemical oxidation / ring-opening of the parent unit. High temperature (>25℃, especially >100 degree) yuav ua kom lub thermal decomposition / tshem tawm cov kev ua haujlwm ntawm pawg niam txiv, ob qho tib si uas yuav ua rau lub luag haujlwm tseem ceeb ntawm cov molecule (chromophore, active site, quaternary ammonium ntsev stability), thaum kawg ua rau ib qho tseem ceeb attenuation los yog ua tsis tiav ntawm nws cov haujlwm tseem ceeb xws li kev loj hlob xim, dyeing, thiab biochemical detection. Ntxiv mus, qhov kev puas tsuaj yog irreversible thiab tsis tuaj yeem rov qab los ntawm recombination los yog optimization txoj kev.
