He aha ka UV 292 CAS 82919-37-7?

He mea hoʻopaʻa kukui wai ʻo UV 292 e hiki ke hoʻolōʻihi i ka manawa hōʻike waho o nā ʻano plastik a me nā uhi like ʻole. I ka wā o ka hana ʻana, ʻaʻole ia e hoʻopuka i kahi ʻala me nā polymers a i ʻole e hoʻopilikia i ke kala mua o ka mea. ʻAʻole ia e maʻalahi ka lele ʻana i ka wā o ka hana ʻana i ka mahana kiʻekiʻe a he kūpono loa ia me ka polymer.

He mea hoʻopaʻa kukui ʻo UV 292 i haku ʻia me ka hui ʻana o ʻelua esters, nona ka hopena synergistic me nā mea hoʻomohu UV benzotriazole a hiki ke pale pono i nā uhi mai ka pahū ʻana a me ka ʻili ʻana o ka ʻili ma lalo o ka lā.

Noi

Hoʻohana nui ʻia ʻo UV 292 i nā polymers organik e like me ka polyethylene, PVC, PVB, ABS resin, polyester, a me ka polyurethane. He kūpono loa ia no ka polyurethane, ʻoiai he solubility maikaʻi ko Light stabilizer 292 i nā solvents.

ʻOi aku ka kūpono o UV 292 no nā uhi kaʻa a me nā uhi ʻoihana. Pena lāʻau, nā uhi ʻoihana paʻakikī māmā, PU resin, nā mea hoʻopili a me nā plastik ʻē aʻe.

Loaʻa iā UV 292 kahi hopena synergistic maikaʻi ke hoʻohana pū ʻia me nā mea hoʻomoʻa UV ʻano benzotriazole, hiki ke hoʻomaikaʻi nui i ke kūpaʻa ʻana o ka huahana i ka wā, ʻoi aku ka maikaʻi ma mua o ka hoʻohana ʻana i nā mea hoʻomoʻa UV wale nō. Ma ka hoʻohui ʻana i nā mea hoʻolaha kūpono, hiki ke kūpono maikaʻi ʻo Light stabilizer 292 no nā uhi wai.
