I-Oxybenzone CAS 131-57-7

Siyakwamukela ukuthenga i-Oxybenzone CAS 131-57-7 kithi. I-Oxybenzone iyisimunyisi se-ultraviolet esine-spectrum esibanzi, esinobuhle bezinga eliphezulu lokumunca, ukungabi nabuthi, akukho teratogenicity, ukukhanya okuhle nokuzinza kokushisa. Ingakwazi ukumunca i-UV-A ne-UV-B ngesikhathi esisodwa. Yisigaba I sokuvikela ilanga esigunyazwe yi-FDA. Isetshenziswa kakhulu kuzimonyo zokuvikela ilanga njengokhilimu ovikela ilanga, ukhilimu, uju, amafutha okugcoba kanye namafutha e-United States naseYurophu. Ingasetshenziswa futhi njenge-ejenti ephikisana nokuguquguquka kwemikhiqizo eshintsha umbala ngenxa ye-photosensitivity. Ngaphezu kwalokho, isetshenziselwa amapulasitiki, imicu yamakhemikhali Emikhiqizweni kapende kanye ne-petroleum, ifaneleka ngokukhethekile emikhiqizweni esobala enombala okhanyayo we-chemicalbook.

I-Oxybenzone CAS 131-57-7

Kuyi-broad-spectrum ultraviolet absorber, enezinzuzo zokumunca okuphezulu, okungeyona ubuthi, akukho teratogenicity, ukukhanya okuhle nokuzinza kokushisa. Ingakwazi ukumunca i-UV-A ne-UV-B ngesikhathi esisodwa. Yisigaba I sokuvikela ilanga esigunyazwe yi-FDA. Isetshenziswa kakhulu kuzimonyo zokuvikela ilanga njengokhilimu ovikela ilanga, ukhilimu, uju, amafutha okugcoba kanye namafutha e-United States naseYurophu. Ingasetshenziswa futhi njenge-ejenti ephikisana nokuguquguquka kwemikhiqizo eshintsha umbala ngenxa ye-photosensitivity. Ngaphezu kwalokho, isetshenziselwa amapulasitiki, imicu yamakhemikhali Emikhiqizweni kapende kanye ne-petroleum, ifaneleka ngokukhethekile emikhiqizweni esobala enombala okhanyayo we-chemicalbook.

Ukusetshenziswa: ingasetshenziswa kupende kanye nemikhiqizo ehlukahlukene yepulasitiki. Isebenza ngokukhethekile ku-PVC, i-polyester, i-acrylic acid, i-resin, i-polystyrene kanye nefenisha ekhanyayo yombala okhanyayo. Futhi iyisengezo esihle sezimonyo. Isilinganiso: 0.1-0.5%.
Sebenzisa i-Cu (II) i-gravimetric determination reagent sebenzisa i-benzophenone ultraviolet absorber iyisiqiniseko esihle kakhulu samapulasitiki okwenziwa njenge-polyethylene. Umthamo ngu-0.5 ~ 1.5%. Ingasetshenziswa futhi kupende, i-pigment, imboni yokuhlanganisa, i-wax emhlophe kanye nezimonyo zansuku zonke.
