Isingeniso

I-Pigment Red 149 i-organic pigment enegama lekhemikhali elithi 2-(4-nitrophenyl)acetic acid-3-amino4,5-dihydroxyphenylhydrazine. Okulandelayo yisingeniso semvelo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha lwe-pigment:

Ikhwalithi:

- I-Pigment Red 149 ibonakala njengento eyimpuphu ebomvu.

- Inobunono obuhle kanye nokumelana nesimo sezulu, futhi ayigqwali kalula ngama-asidi, ama-alkali nezincibilikisi.

- I-Pigment Red 149 ine-chromaticity ephezulu, umbala ogqamile futhi ozinzile.

Sebenzisa:

- I-Pigment Red 149 ivame ukusetshenziswa njengesibala esibomvu ezimbonini ezinjengopende, okokunamathela, amapulasitiki, irabha nezindwangu.

- Ingasetshenziselwa ukulungisa umbala noyinki, kanye nasezindaweni ezinjengodayi, oyinki, nokuphrinta kwe-offset yemibala.

Indlela:

- Ukulungiswa kombala obomvu we-pigment 149 ngokuvamile kwenzeka ngokusabela kwe-aniline ne-nitrobenzene ukuze kutholwe izinhlanganisela ze-nitroso, bese kuba nokusabela kwe-o-phenylenediamine nezinhlanganisela ze-nitroso ukuze kutholwe umbala obomvu ongu-149.

Ulwazi Lokuphepha:

- Gqoka izinto zokuzivikela ezifanele njengamagilavu, imaski, nezibuko ngesikhathi sokusebenzisa.

- Gwema ukulahla ngokuqondile endaweni ezungezile futhi uphathe futhi ugcine ngendlela efanele.

- Uma usebenzisa i-Pigment Red 149, kufanele isetshenziswe ngokuhambisana ngokuqinile nezinqubo ezifanele zokusebenza zokuphepha ukuze kuqinisekiswe ukuphepha nempilo.

Okwedlule: I-Pigment Ebomvu 144 CAS 5280-78-4

Olandelayo: I-Pigment Red 166 CAS 3905-19-9
