Iyini i-UV 292 CAS 82919-37-7?

I-UV 292 iyisinzinzisi sokukhanya okuwuketshezi esinganweba isikhathi sokuchayeka ngaphandle samapulasitiki ahlukahlukene nezingubo. Ngesikhathi sokucutshungulwa, akukhiqizi iphunga ngama-polymers noma kuthinte umbala wangempela wento. Ayiguquguquki kalula ngesikhathi sokucutshungulwa kwezinga lokushisa eliphezulu futhi inokuhambisana okuphezulu kwe-polymer.

I-UV 292 iyisinzinzisi esikhanyayo esakhiwe ngengxube yama-ester amabili, esinomphumela wokusebenzisana nama-absorptor we-benzotriazole UV futhi engavimbela ngempumelelo okunamathelayo ekuqhumeni nokuxebuka kwendawo ngaphansi kokuchayeka elangeni.

Isicelo

I-UV 292 isetshenziswa kakhulu kuma-polymers ephilayo njenge-polyethylene, i-PVC, i-PVB, i-ABS resin, i-polyester, ne-polyurethane. Ifaneleka kakhulu i-polyurethane, njengoba i-Light stabilizer 292 inokunyibilika okuhle kuma-solvents.

I-UV 292 ifaneleka kakhudlwana ezingubo zezimoto nezasezimbonini. Upende wokhuni, indwangu yezimboni eqinisa ukukhanya, i-PU resin, izinto zokunamathisela namanye amapulasitiki.

I-UV 292 inomphumela omuhle we-synergistic uma isetshenziswa kanye nezibambisi ze-UV zohlobo lwe-benzotriazole, ezingathuthukisa ngokuphawulekayo ukumelana nesimo sezulu somkhiqizo, kangcono kakhulu kunokusebenzisa izimunyisi ze-UV zodwa. Ngokungeza ama-dispersants afanelekile, i-Light stabilizer 292 ingafanelana kahle nezingubo ezisekelwe emanzini.
