Ulwazi lweMarike yeePigments kunye neDayi kule Veki (26th Sep. - 2nd Oct.)

Ii-Pigments ze-Organic

I-Pigment Yellow 12, Pigment Yellow 13, Pigment Yellow 14, Pigment Yellow 17, Pigment Yellow 83, Pigment Yellow 13, Pigment Yellow 16.

Ithuba lokunyuka kwexabiso elilandelayo ngenxa yokukhula kwe-DCB kwimfuno yezinto eziphambili zekrwada -

I-o-nitro impahla kunye ne-phthalic anhydride, i-phenol, kunye nexabiso le-aniline liqhubekile ukunyuka.

Umzi-mveliso we-DCB uyekile uqikelelo-mali lwangaphandle okwangoku ngenxa yokwenyuka kwamaxabiso.

I-Pigment eBomvu 48:1, i-Pigment Red48:3, i-Pigment eBomvu 48:4, i-Pigment eBomvu 53:1, i-Pigment eBomvu 57:1.

I-asidi ye-2B (izinto eziphambili ze-Azo Pigments) amaxabiso azinzile kule veki.

Ke ixabiso leqela le-Azo pigment liya kuhlala lizinzile kwiveki enye ezayo.

I-Pigment Yellow 180&I-Pigment Orange 64

I-AABI ekrwada isahlala izinzile, nangona kunjalo umenzi unokulungelelanisa ixabiso (ukunciphisa ixabiso) ngeveki ezayo ngenxa yokuba imarike ibuthathaka.

I-Pigment eBomvu 122&I-Pigment Violet 19

Ixabiso lihlala liqinile okwangoku, kodwa ixabiso le-phosphorus eliphuzi likhuphuka kancinci kule veki.

Akukho phawu lucacileyo lokunyuka kwexabiso kuzo zombini i-PR122 kunye ne-PV19 kwiveki ezayo.

I-Phthalocyanine Pigments

Uthotho lwePigment Blue 15 kunye nePigment Green 7

Kukho ithuba lokuba ixabiso elilandelayo liya kunyuka ngenxa yezinto eziphambili zekrwada

(phthalic anhydride, cuprous chloride, ammonium lacrimal acid) amaxabiso ayanyuka kule veki.

Idayi ezinyibilikayo

Imarike yedayi isekwindlela ebuthathaka kule veki.

Nangona kunjalo, i-Solvent Red 23, i-Solvent Red 24, kunye ne-Solvent Red 25 amaxabiso anyuka ngenxa yezinto ezisisiseko (i-aniline, i-hydrochloric acid, i-liquid caustic soda, kunye ne-o-toluidin).

Amanye amaxabiso ezinto eziluhlaza athobile, njenge-PMP (1-phenyl-3-methyl-5-pyrazolinone), 1,8-diaminos, 1-nitroanthraquinone, 1,4 dihydroxy anthraquinone, kunye ne-DMF.

Nangona kunjalo, ixabiso ledayi ye-solvent lisezantsi kwaye amathuba okulungelelaniswa okulandelayo kuphakamileyo ngenxa yeemfuno zokunyuka kwixesha le-4.
