UV-144 CAS 63843-89-0 ni iki?

Ifu y'umweru kugeza ku muhondo muto ya UV-144, ifite ubushobozi bwo hejuru bwo gukingira urumuri rwa amine, ikwiriye inganda zisiga ifu. Ingufu zigabanya ubukana bwa amine zifite imiterere ya phenolic antioxidant ishobora kugabanya gucika no gutakaza urumuri, bigatuma amarangi aramba cyane.

Porogaramu

UV-144 ifite ubushobozi bwo hejuru bwo gukingira imirasire y'urumuri rwa amine, ikwiriye inganda zikora ifu. Ifite ubushobozi bwo gukingira imirasire y'amine ifite ubushobozi bwo gukingira imirasire y'amine ishobora kugabanya gucika no gutakaza urumuri, bigatuma amarangi aramba cyane. Muri icyo gihe, ifite ubushobozi bwo gukora ifu ikora nk'iy'ingufu kandi ishyushye, bigatuma ifu irushaho gukwirakwira. Ikoreshwa cyane cyane mu ifu ikora, mu byuma bikonjesha, mu byuma bikonjesha imodoka, nibindi.
