Isingeniso
I-pigment yellow 14, eyaziwa nangokuthi i-barium dichromate yellow, i-pigment ephuzi evamile. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-Yellow 14:
Ikhwalithi:
- Ukubukeka: Okuphuzi 14 kuyimpushana ephuzi.
- Isakhiwo samakhemikhali: I-pigment ye-inorganic enesakhiwo samakhemikhali se-BaCrO4.
- Ukuqina: Okuphuzi 14 kunokuqina okuhle futhi akuthintwa kalula ukukhanya, ukushisa kanye nemiphumela yamakhemikhali.
- Izakhiwo ze-Spectral: I-Yellow 14 iyakwazi ukumunca ukukhanya kwe-ultraviolet nokukhanya okuluhlaza okwesibhakabhaka, okubonisa ukukhanya okuphuzi.
Sebenzisa:
- I-Yellow 14 isetshenziswa kabanzi kuma-coatings, amapende, amapulasitiki, irabha, izitsha zobumba nezinye izimboni ukunikeza imiphumela yombala ophuzi.
- Ibuye isetshenziswe ngokujwayelekile emkhakheni wezobuciko nokudweba njengosizo lombala.
Indlela:
- Ukulungiswa kwe-yellow 14 kuvame ukutholwa ngokuphendula i-barium dichromate ne-barium salt ehambisanayo. Izinyathelo eziqondile zihilela ukuxuba kokubili, ukufudumeza kumazinga okushisa aphezulu futhi uwabambe isikhathi esithile, bese uwapholisa futhi uwahlunge ukuze akhiqize imvula ephuzi, futhi ekugcineni yome.
Ulwazi Lokuphepha:
- I-Yellow 14 iwumbala ophephile uma kuqhathaniswa, kodwa kusenezinyathelo zokuphepha okufanele uziqaphele:
- Gwema ukuhogela umoya noma ukuthintana nempushana ephuzi 14 ukugwema ukucasuka komgudu wokuphefumula kanye nesikhumba.
