He aha ka UV-144 CAS 63843-89-0?

ʻO ka pauka UV-144 keʻokeʻo a melemele iki paha, ka mea hoʻopaʻa māmā amine ʻano NOR hana kiʻekiʻe, kūpono no ka ʻoihana uhi pauka. Hiki i nā mea hoʻopaʻa amine ʻākea me ka hana antioxidant phenolic i ākea hapa ʻia ke hōʻemi i ka nahā a me ka nalowale o ka ʻōlinolino, e hoʻolōʻihi nui ana i ke ola lawelawe o nā kiʻiʻoniʻoni pena.

ʻO ka mea hoʻopaʻa māmā amine hindered ʻano NOR kiʻekiʻe UV-144, kūpono no ka ʻoihana uhi pauka. Hiki i nā mea hoʻopaʻa amine hindered me ka hana antioxidant phenolic hindered hapa ke hōʻemi i ka haki a me ka nalowale o ka ʻōlinolino, e hoʻolōʻihi nui ana i ke ola lawelawe o nā kiʻiʻoniʻoni pena. I ka manawa like, loaʻa iā ia ka waiwai o ka hana ʻana i nā uhi pauka frictional a hoʻouka ʻia, e hoʻomaikaʻi ana i ka wikiwiki o ka uhi pauka. Hoʻohana nui ʻia ia i nā uhi pauka, ke kila coil, nā uhi kaʻa, a pēlā aku.
