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

Light stabilizer 3638 ndi yolemera kwambiri maselo, osasunthika otsika komanso banga lopanda mtundu. Makamaka oyenera kutengera mtundu wamtundu wamtundu wa Optical. Light stabilizer 3638 ili ndi chokhazikika chotentha kwambiri chokhala ndi TGA (10%) kuposa madigiri 371 Celsius. Kuwala kwa stabilizer 3638 ndi m'badwo watsopano wokonda zachilengedwe komanso woyenga bwino wa ultraviolet. Kwa UVB, UVC imakhala ndi mayamwidwe apamwamba kwambiri.

Kugwiritsa ntchito

UV-3638 ndi kulemera kwakukulu kwa maselo, kusinthasintha kochepa, kuipitsidwa kopanda mtundu. Ndikoyenera makamaka kwa makampani opanga kuwala komwe kumafuna mtundu wa transmittance, monga PET, magalasi a PC optical material, diffuser kuwala kwa backlit liquid crystal display zipangizo, etc. Uv-3638 imapereka mayamwidwe amphamvu kwambiri komanso ambiri a UV, kuipitsidwa kopanda mtundu. UV-3638 ndi yoyenera ku mafakitale a polyester a thermoplastic, nayiloni, ndi zodzitchinjiriza zomwe zimakhala ndi kutentha kwambiri komanso zofunika kwambiri pakuyamwa kwa UV.
