Mawu Oyamba

Pigment Red 149 ndi organic pigment yokhala ndi dzina lamankhwala la 2-(4-nitrophenyl)acetic acid-3-amino4,5-dihydroxyphenylhydrazine. Zotsatirazi ndizofotokozera zamtundu, kagwiritsidwe ntchito, njira yokonzekera ndi chidziwitso cha chitetezo cha pigment:

Ubwino:

- Pigment Red 149 imawoneka ngati ufa wofiira.

- Imakhala ndi kupepuka kwabwino komanso kukana nyengo, ndipo siyiwonongeka mosavuta ndi zidulo, ma alkalis ndi zosungunulira.

- Pigment Red 149 ili ndi chromaticity yayikulu, yowala komanso yokhazikika.

Gwiritsani ntchito:

- Pigment Red 149 imagwiritsidwa ntchito ngati utoto wofiira m'mafakitale monga utoto, zokutira, mapulasitiki, mphira ndi nsalu.

- Itha kugwiritsidwa ntchito popanga utoto ndi inki, komanso m'minda monga utoto, inki, ndi kusindikiza kwamitundu.

Njira:

- Kukonzekera kwa pigment red 149 nthawi zambiri kumachitika chifukwa cha aniline ndi nitrobenzene kuti apeze mankhwala a nitroso, ndiyeno zomwe o-phenylenediamine ndi mankhwala a nitroso kuti apeze mtundu wofiira 149.

Zambiri Zachitetezo:

- Valani zida zodzitetezera zoyenera monga magolovesi, masks, ndi magalasi mukamagwiritsa ntchito.

- Pewani kutaya mwachindunji m'chilengedwe ndikusunga ndikusunga moyenera.

- Mukamagwiritsa ntchito Pigment Red 149, iyenera kuyendetsedwa motsatira njira zoyendetsera chitetezo kuti zitsimikizire chitetezo ndi thanzi.
