Ulwazi Lwemakethe Yemibala Nemibala Kuleli viki (26th Sep. – 2nd Oct.)

Organic Pigments

I-Pigment Yellow 12, Pigment Yellow 13, Pigment Yellow 14, Pigment Yellow 17, Pigment Yellow 83, Pigment Orange 13, Pigment Yellow16.

Amathuba okunyuka kwamanani alandelayo ngenxa yokukhula kwe-DCB kwesidingo sempahla eyinhloko -

i-o-nitro impahla kanye ne-phthalic anhydride, i-phenol, nentengo ye-aniline iqhubekile nokukhuphuka.

Ifekthri ye-DCB imise ikhotheshini yangaphandle okwamanje ngenxa yamathuba okunyuka kwentengo.

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

I-2B acid (impahla eyinhloko ye-Azo Pigments) izintengo azishintshi kuleli sonto.

Ngakho intengo yeqembu le-Azo pigment izozinza evikini elilodwa elizayo.

I-Pigment Yellow 180&I-Pigment Orange 64

I-AABI eluhlaza isalokhu izinzile, nokho umkhiqizi angase alungise intengo (ukwehliswa kwentengo) ngesonto elizayo ngenxa yokuthi imakethe ibuthaka.

I-Pigment Ebomvu 122&I-Pigment Violet 19

Intengo isalokhu iqinile njengamanje, kodwa intengo ye-phosphorus ephuzi ikhuphuka kancane kuleli sonto.

Alukho uphawu olucacile lokukhuphuka kwentengo yakho kokubili i-PR122 ne-PV19 evikini elizayo.

I-Phthalocyanine Pigments

I-Pigment Blue 15 series & Pigment Green 7

Kukhona amathuba okuthi intengo elandelayo nayo izokwenyuka ngenxa yezinto ezingavuthiwe eziyinhloko

(i-phthalic anhydride, cuprous chloride, ammonium lacrimal acid) amanani akhuphuka kuleli sonto.

I-Solvent Dyes

Imakethe yedayi isesesimweni esibuthakathaka kuleli sonto.

Nokho, izintengo zeSolvent Red 23, Solvent Red 24, neSolvent Red 25 ziyenyuka ngenxa yezinto ezisetshenziswayo eziyisisekelo (i-aniline, i-hydrochloric acid, i-liquid caustic soda, ne-o-toluidin).

Ezinye izintengo zezinto zokusetshenziswa zehla, njenge-PMP (1-phenyl-3-methyl-5-pyrazolinone), 1,8-diaminos, 1-nitroanthraquinone, 1,4 dihydroxy anthraquinone, ne-DMF.

Kodwa-ke, intengo yedayi ye-solvent isezingeni eliphansi futhi amathuba okulungiswa okulandelayo aphakeme kakhulu ngenxa yezidingo ezikhulayo ngenkathi yesi-4.
