Mawu Oyamba

Solvent yellow 33 ndi utoto wosungunulira wa organic wokhala ndi mtundu wachikasu-lalanje, ndipo dzina lake lamankhwala ndi bromophenol yellow. Solvent Yellow 33 ili ndi izi:

 

1. Kukhazikika kwamtundu: zosungunulira zachikasu 33 zimasungunuka mu organic zosungunulira kutentha kwa firiji, kusonyeza yankho la lalanje-chikasu, ndi kukhazikika kwamtundu wabwino.

 

2. Kusungunuka: zosungunulira zachikasu 33 zimasungunuka mu zosungunulira za organic monga ma alcohols, ketoni, esters, aromatics, etc., koma osasungunuka m'madzi.

 

3. Kukana kwazitsulo zosungunulira: Zosungunulira zachikasu 33 zimakhala ndi kusungunuka kwakukulu mu zosungunulira ndipo zimakhala ndi zosungunulira zabwino.

 

Ntchito zazikulu za zosungunulira zachikasu 33 zikuphatikizapo:

 

1. Mitundu ya utoto: Monga organic zosungunulira utoto, zosungunulira yellow 33 nthawi zambiri ntchito zokutira, inki, mapulasitiki, mphira, ulusi ndi minda ina kupereka mankhwala lalanje chikasu.

 

2. Utoto wapakatikati: zosungunulira zachikasu 33 zitha kugwiritsidwanso ntchito ngati utoto wapakatikati, womwe ungagwiritsidwe ntchito ngati zopangira popanga utoto wina wa pigment.

 

Njira zodziwika bwino zopangira zosungunulira zachikasu 33 ndi:

 

1. kaphatikizidwe njira: zosungunulira chikasu 33 akhoza kukonzekera bromine mu phenol bromination, ndiyeno acidification, sulfonation, alkylation ndi zina Mipikisano sitepe zimachitikira.

 

2. Njira ya okosijeni: zosungunulira zachikasu 33 zimathiridwa ndi okosijeni pamaso pa chothandizira kuti apange zosungunulira zachikasu 33.

 

Zambiri zachitetezo cha zosungunulira zachikasu 33 zili motere:

 

1. Zosungunulira zachikasu 33 zimakhala ndi mphamvu zinazake, zimatha kuyambitsa kuyabwa, kuyabwa pakhungu ndi maso, komanso zida zoyenera zodzitetezera ziyenera kuvalidwa.

 

2. Mukamagwiritsa ntchito, pewani kutulutsa fumbi kapena madzi osungunulira achikasu 33, ndipo pewani kukhudzana ndi khungu ndi maso.

 

3. Mukakhala mwangozi kukhudzana ndi zosungunulira yellow 33, muzimutsuka malo okhudzidwa mwamsanga ndi madzi ambiri.

 

4. Zosungunulira zachikasu 33 ziyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino kuti asakhudzidwe ndi okosijeni, ma asidi, alkalis ndi zinthu zina.
