Iyini i-UV 538 CAS 2985-59-3?

I-UV 538 engenabuthi, engashi, ayiqhumi, ayigqwali, ukuqina kwesitoreji esihle, ingakwazi ukumunca ukukhanya kwe-ultraviolet okungu-270-340nm, ivimbele ukwakheka kwe-polymer ekuthatheni izithombe, ukuqhekeka kanye nokushintshashintsha okuphukayo, inwebe kakhulu impilo yesevisi yezinto ezibonakalayo. . Ifomula yamangqamuzana ye-UV-1200 yi-C25H34O3, futhi isibambisi se-ultraviolet i-UV-1200 sithatha indawo ye-UV-531 ne-UV-9.

Isicelo

I-UV emunca i-UV-1200 ithatha indawo ye-UV-531 ne-UV-9. Umkhiqizo awunabo ubuthi, awushisi, awuqhumi, awugqwali, uzinzo oluhle lokugcina, ungamunca ukukhanya kwe-ultraviolet kwe-270-340nm, i-Chemicalbook ukuvimbela ukuthwebula izithombe, ukuqhekeka kanye nezinto eziphukayo ze-polymer, ukwandisa kakhulu impilo yesevisi yezinto ezibonakalayo. . Ngenxa yokusebenza kwayo okuhle kakhulu, isetshenziswa kabanzi ku-polyethylene, i-polypropylene, i-acrylic, i-coatings ehlukahlukene yezinga eliphezulu kanye nopende bezimoto phesheya.
