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

UV-144 yera nifu yumuhondo muto, imikorere ya NOR ikora cyane yabangamiye urumuri rwa amine, rukwiranye ninganda zifata ifu. Inzitizi za amine zibangamira imyitwarire ya antioxydants ya fenolike ibangamira igice gishobora kugabanya gucika no gutakaza ububengerane, bikongerera igihe kinini umurimo wamafirime.

Gusaba

UV-144 ikora cyane NOR yabangamiye urumuri rwa amine, rukwiranye ninganda zifata ifu. Inzitizi za amine zibangamira imyitwarire ya antioxydants ya fenolike ibangamira igice gishobora kugabanya gucika no gutakaza ububengerane, bikongerera igihe kinini umurimo wamafirime. Muri icyo gihe, ifite umutungo wo gukora ifu yifu yivanze kandi ikarishye, ikazamura igipimo cyifu. Ikoreshwa cyane cyane mu ifu yifu, ibyuma bya coil, ibinyabiziga, nibindi.
