Isingeniso

I-Solvent Yellow 176, eyaziwa nangokuthi i-Dye Yellow 3G, ingudayi we-organic solvent. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Isakhiwo samakhemikhali: Isakhiwo samakhemikhali se-solvent yellow 176 ingudayi we-phenyl azo paraformate.

- Ukubukeka Nombala: I-Solvent Yellow 176 iyimpushana ecwebezelayo ephuzi.

- Ukunyibilika: I-solvent Yellow 176 iyancibilika kuzincibilikisi zemvelo ezifana ne-ethanol, i-acetone ne-methylene chloride, futhi cishe ayincibiliki emanzini.

 

Sebenzisa:

- Imboni yodayi: I-Solvent Yellow 176 ivame ukusetshenziswa njengodayi we-solvent ephilayo futhi ingasetshenziswa ekulungiseni izinhlobo ezahlukene zodayi noyinki.

- Imboni yokunyathelisa: Ingasetshenziswa njengombala ezitembu zenjoloba noyinki wokunyathelisa.

- Izibonisi ze-Fluorescent: Ngenxa yezakhiwo zayo ze-fluorescent, i-solvent yellow 176 nayo isetshenziswa ekukhanyeni okungemuva kwezibonisi ze-fluorescent.

 

Indlela:

- I-solvent yellow 176 ingatholwa ngokuhlanganiswa kodayi be-formate ester, futhi indlela ethile yokuhlanganisa ingalungiswa ngokuya ngezidingo zokusabela kwamakhemikhali.

 

Ulwazi Lokuphepha:

- I-Solvent Yellow 176 ayifaki ingozi enkulu ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Njengento yamakhemikhali, lezi zinyathelo zokuphepha ezilandelayo kusafanele ziqashelwe uma uyisebenzisa:

- Gwema ukuhogela umoya noma ukuthintana nesikhumba namehlo.

- Uma kwenzeka uthinta isikhumba, geza ngokushesha ngensipho namanzi amaningi.

- Gqoka amagilavu ​​okuvikela afanelekile kanye nokuvikela amehlo lapho usebenzisa.

- Uma usebenzisa noma ugcina i-solvent yellow 176, landela imithetho yendawo yendawo bese uyigcina endaweni eyomile, epholile.
