CYASORB UV-3638 CAS 18600-59-4 ni iki?

Stabilisateur yumucyo 3638 ifite uburemere buke bwa molekile, ihindagurika rike hamwe nibara ritagira ibara. Byumwihariko bikwiranye nibisabwa byoherejwe hejuru yinganda zinganda. Light stabiliser 3638 ifite stabilisateur yumuriro mwinshi hamwe na TGA (10%) irenga dogere selisiyusi 371. Light stabilizer 3638 nigisekuru gishya cyangiza ibidukikije kandi gikora neza ultraviolet. Kuri UVB, UVC ifite uburyo bwiza bwo kwinjiza.

Gusaba

UV-3638 nuburemere buke bwa molekile, ihindagurika rito, umwanda utagira ibara. Irakwiriye cyane cyane mubikorwa bya optique isaba ibara ryogukwirakwiza, nka PET, PC optique yibikoresho bya PC, diffuser yumucyo wibikoresho byerekana ibyuma byerekana ibintu, nibindi Uv-3638 itanga imbaraga zikomeye kandi nini cyane zo kwinjiza UV, umwanda utagira ibara. UV-3638 ibereye inganda za polimester, nylon, ninganda zirinda ubushyuhe bwinshi kandi bisabwa cyane kugirango UV yinjire.
