Isingeniso

I-Solvent Yellow 44 yaziwa nangokuthi i-Sudan Yellow G kukhemistri, futhi ukwakheka kwayo kwamakhemikhali kuyi-chromate ye-Sudan Yellow G. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-Solvent Yellow 44 iyimpushana ecwebezelayo esuka kuwolintshi-ophuzi ukuya kokubomvu-ophuzi.

- Ukunyibilika: kuncibilika emanzini, i-methanol, i-ethanol, ayincibiliki ku-ether, benzene nezinye izinyibilikisi zemvelo.

 

Sebenzisa:

- Udayi wamakhemikhali: ophuzi oncibilikayo 44 ungasetshenziswa njengodayi kumadayi kanye nokulebula ama-reagents.

 

Indlela:

I-solvent yellow 44 ilungiswa ngokuyinhloko ukusabela kwe-sodium chromate ne-Sudan yellow G kusisombululo esinamanzi.

 

Ulwazi Lokuphepha:

- I-Solvent Yellow 44 ingudayi wamakhemikhali futhi kufanele iphathwe ngokucophelela ukugwema ukuhogela uthuli noma ukuthinta isikhumba, amehlo, njll.

- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nezingubo zokuzivikela ngesikhathi sokusebenzisa.

- Uma uhogela umoya noma uthinta isikhumba, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.

- Ngesikhathi sokugcina, i-solvent yellow 44 kufanele ibekwe endaweni eyomile, epholile, enomoya omuhle ukuze kugwenywe ukuthintana nokuthungela, ama-oxidants noma ezinye izinto ezisebenzayo.

 

Ngokuvamile, ukusetshenziswa kwe-solvent yellow 44 kufanele kwenziwe ngokuhambisana nezinqubo zokusebenza eziphephile futhi ngokusho kwendawo ethile yesicelo kanye nezidingo zokulawula.
