Iyini i-CYASORB UV-3638 CAS 18600-59-4?

Isiqinisi sokukhanya 3638 sinesisindo esikhulu sama-molecule, ukuguquguquka okuphansi kanye nebala elingenambala. Ifaneleka kakhulu ezidingweni zombala zokudlulisa okuphezulu embonini ye-optical. Isiqinisi sokukhanya 3638 sine-stabilizer ephezulu yokushisa ene-TGA(10%) engaphezu kwama-degree Celsius angu-371. Isiqinisi sokukhanya 3638 siyisizukulwane esisha se-ultraviolet absorber enobungani nemvelo futhi esebenza kahle. Ku-UVB, i-UVC inomuncwa osebenza kahle kakhulu.

Isicelo

I-UV-3638 inesisindo esikhulu sama-molecule, ukuguquguquka okuphansi, ukungcola okungenambala. Ifaneleka kakhulu embonini yokukhanya edinga umbala wokudlulisa, njenge-PET, amalensi ezinto ezibonakalayo ze-PC, i-diffuser yokukhanya yamadivayisi okubonisa ikristalu elicwebezelayo elingemuva, njll. I-UV-3638 inikeza ukumuncwa kwe-UV okunamandla kakhulu futhi okubanzi, ukungcola okungenambala. I-UV-3638 ifanelekela izimboni ze-thermoplastic polyester, i-nylon, kanye nezokuvikela ezinamazinga okushisa aphezulu okucubungula kanye nezidingo eziqinile zokumuncwa kwe-UV.
