Intshayelelo

I-pigment yellow 138, eyaziwa ngokuba yintyatyambo ekrwada emthubi, ixilongo elityheli, igama lekhemikhali yi-2,4-dinitro-N-[4-(2-phenylethyl)phenyl]aniline. Oku kulandelayo sintshayelelo kwezinye zeepropati, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko lweYellow 138:

 

Umgangatho:

- I-Yellow 138 ngumgubo wekristale omthubi, onyibilika ngokulula kwizinyibilikisi zezinto eziphilayo, ezinjenge-methanol, i-ethanol, njl., kwaye ezinganyibilikiyo emanzini.

- Ubume balo beekhemikhali bugqiba ukuba bune-photostability elungileyo kunye nokumelana nobushushu.

- I-Yellow 138 inozinzo oluhle phantsi kweemeko ze-acidic, kodwa ithanda ukuguquguquka phantsi kweemeko ze-alkaline.

 

Sebenzisa:

-Yellow 138 isetyenziswa ikakhulu njenge pigment ephilayo kwaye isetyenziswa kakhulu kwiipeyinti, ii-inki, iiplastiki kunye namanye amashishini.

- Ngenxa yombala otyheli ocacileyo kunye nokukhawuleza kombala olungileyo, iYellow 138 ihlala isetyenziswa njengepigment kwipeyinti yeoli, ipeyinti yombala wamanzi, ipeyinti ye-acrylic kunye nezinye iindawo zobugcisa.

 

Indlela:

- Indlela yokulungiselela i-yellow 138 inzima ngakumbi, kwaye idla ngokufunyanwa ngokusabela kwe-oxidation kunye nee-amino compounds.

- Indlela ethile yokulungiselela ingabandakanya ukusabela kwe-nitroso compounds kunye ne-aniline ukufumana i-2,4-dinitro-N-[4-(2-phenylethyl) phenyl]imine, kwaye emva koko ukuphendula kwemine nge-hydroxide yesilivere ukulungiselela i-Huang 138 .

 

Ulwazi ngoKhuseleko:

- Umthubi 138 uthathwa ngokuba uzinzile kwaye ukhuselekile ngokwemeko phantsi kweemeko zokusetyenziswa kwesiqhelo.

- I-Yellow 138 ithanda ukujika umbala phantsi kweemeko zealkaline, ngoko ke ukudibana nezinto zealkaline kufuneka kuphetshwe.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
