Mawu Oyamba

Pigment Yellow 74 ndi organic pigment yomwe ili ndi dzina la mankhwala CI Pigment Yellow 74, yomwe imadziwikanso kuti Azoic Coupling Component 17. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha Pigment Yellow 74:

 

Ubwino:

- Pigment Yellow 74 ndi ufa wonyezimira wachikasu wokhala ndi zida zabwino zodaya.

- Simasungunuka m'madzi koma amasungunuka mu zosungunulira zina monga ma alcohols, ketones, ndi esters.

- Pigment imakhazikika pakuwala komanso kutentha.

 

Gwiritsani ntchito:

- Pazinthu zapulasitiki, Pigment Yellow 74 itha kugwiritsidwa ntchito popanga jakisoni, kuumba nkhonya, kutulutsa ndi njira zina zowonjezera mapulasitiki kuti awapatse mtundu wachikasu.

 

Njira:

- Pigment Yellow 74 nthawi zambiri imakonzedwa ndi kaphatikizidwe, komwe kumafuna kugwiritsa ntchito ma reagents angapo amankhwala ndi othandizira.

- Njira zenizeni zokonzekera ndikuphatikiza, kulumikizana ndi kudaya, ndipo pamapeto pake utoto wachikasu umapezeka ndi kusefera kwa mpweya.

 

Zambiri Zachitetezo:

- Pigment Yellow 74 nthawi zambiri imadziwika kuti ndiyotetezeka ngati ikugwiritsidwa ntchito bwino.

- Kusamalira moyenera kuyenera kutsatiridwa mukamagwiritsa ntchito pigment iyi, monga kupewa kutulutsa ufa komanso kupewa kukhudzana ndi maso ndi khungu.

- Mukapuma mwangozi kapena kukhudzana ndi pigment, muzimutsuka nthawi yomweyo ndi madzi oyera ndikufunsana ndi dokotala kuti aunike ndi chithandizo.
