Mawu Oyamba

Solvent Yellow 44 imadziwikanso kuti Sudan Yellow G mu chemistry, ndipo kapangidwe kake ka mankhwala ndi chromate ya Sudan Yellow G. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira zopangira ndi chitetezo:

 

Ubwino:

- Maonekedwe: Zosungunulira Yellow 44 ndi ufa wa crystalline kuchokera ku lalanje-chikasu mpaka kufiira-chikasu.

- Kusungunuka: kusungunuka m'madzi, methanol, ethanol, osasungunuka mu ether, benzene ndi zosungunulira zina.

 

Gwiritsani ntchito:

- Utoto wa Chemical: zosungunulira zachikasu 44 zitha kugwiritsidwa ntchito ngati utoto mu utoto ndikulemba ma reagents.

 

Njira:

Chosungunulira chachikasu 44 chimakonzedwa makamaka ndi momwe sodium chromate ndi Sudan yellow G mu njira yamadzimadzi.

 

Zambiri Zachitetezo:

- Solvent Yellow 44 ndi utoto wamankhwala ndipo uyenera kugwiridwa mosamala kuti usapume fumbi kapena kukhudzana ndi khungu, maso, ndi zina zambiri.

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

- Mukakoka mpweya kapena kukhudza khungu, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala.

- Pakusungirako, zosungunulira zachikasu 44 ziyenera kuyikidwa pamalo owuma, ozizira, olowera mpweya wabwino kuti asakhudzidwe ndi kuyatsa, okosijeni kapena zinthu zina zotakataka.

 

Kawirikawiri, kugwiritsa ntchito zosungunulira zachikasu 44 kuyenera kuchitidwa motsatira njira zotetezeka zogwirira ntchito komanso molingana ndi malo ogwiritsira ntchito komanso zofunikira zoyendetsera.
