Kodi CYASORB UV-3638 CAS 18600-59-4 ndi chiyani?

Cholimbitsa kuwala 3638 ndi cholemera kwambiri cha mamolekyulu, chosasinthasintha kwenikweni komanso chopanda utoto. Choyenera kwambiri pakufunika kwa mitundu yotumizira kwambiri ya makampani opanga kuwala. Cholimbitsa kuwala 3638 chili ndi cholimbitsa kutentha kwambiri chokhala ndi TGA(10%) yoposa madigiri 371 Celsius. Cholimbitsa kuwala 3638 ndi mbadwo watsopano wa choyamwa ultraviolet choteteza chilengedwe komanso chogwira ntchito bwino. Pa UVB, UVC imayamwa bwino kwambiri.

Kugwiritsa ntchito

UV-3638 ndi yolemera kwambiri, yosasinthasintha, yopanda mtundu. Ndi yoyenera makamaka makampani opanga kuwala omwe amafunikira mtundu wotumizira, monga PET, ma PC optical material lens, kuwala kotulutsa kuwala kwa zida zowonetsera zamadzimadzi zowala kumbuyo, ndi zina zotero. Uv-3638 imapereka kuyamwa kwamphamvu kwambiri kwa UV, kuipitsa kopanda mtundu. UV-3638 ndi yoyenera mafakitale a thermoplastic polyester, nayiloni, ndi chitetezo omwe ali ndi kutentha kwambiri komanso zofunikira kwambiri kuti ayamwe UV.
