Ukusetshenziswa
I-ultraviolet absorber UV-9 iyimpuphu ephuzi noma emhlophe ecwebezelayo, eyaziwa nangokuthi i-Sunscreen Agent No. 2 kanye ne-BP-3. Ifaneleka kumapulasitiki ahlukahlukene njenge-polyvinyl chloride, i-polyvinylidene chloride, i-polymethyl methacrylate, i-unsaturated polyester, i-ABS resin, kanye ne-cellulose resin. Ububanzi bayo obukhulu bokumunca bungama-nanometer angu-280-340, kanye nomthamo ojwayelekile ongu-0.1-1.5%. Iqinile ekushiseni futhi ayiboli ku-200°C. Lo mkhiqizo awumunci ukukhanya okubonakalayo, ngakho-ke ufaneleka emikhiqizweni enombala okhanyayo necacile. Ingasetshenziswa futhi kupende kanye nerabha yokwenziwa. Njenge-broad-spectrum ultraviolet absorber evela ku-Chemicalbook, inezinzuzo zesilinganiso esiphezulu sokumunca, ukungabi nobuthi, ukungabi nomthelela we-teratogenic, kanye nokuqina okuhle ekukhanyeni nasekushiseni. I-ultraviolet absorber UV-9 ingamunca kokubili i-UV-A kanye ne-UV-B. Iyisivikelo selanga se-Class Ⅰ esivunyelwe yi-US FDA, futhi sivame ukusetshenziswa e-United States nakwamanye amazwe aseYurophu. I-UV-9 isetshenziswa kabanzi ezimonyweni zokuvikela ilanga njenge-sunscreen creams, ama-lotion, ubisi, ama-emulsions, namafutha. Ingasetshenziswa futhi njenge-ejenti yokulwa nokushintsha kombala emikhiqizweni eshintsha umbala ngenxa yokuzwela ukukhanya kwelanga. Ngaphezu kwalokho, ngenxa yokuhambisana kwayo kahle namapulasitiki amaningi nama-resin, ivame ukusetshenziswa emikhakheni eminingi efana ne-PVC kanye ne-polyester engagcwali.
Isithambisi se-UV i-UV-9 iyisithambisi se-UV esibanzi esinezinzuzo ezifana nesilinganiso esiphakeme sokumuncwa, ukungabi nobuthi, ukungabi nomthelela we-teratogenic, kanye nokuzinza okuhle ekukhanyeni nasekushiseni. Ingamuncwa kokubili i-UV-A kanye ne-UV-B. Iyisithambisi selanga se-Class Ⅰ esivunyelwe yi-US FDA, futhi sivame ukusetshenziswa e-United States naseYurophu. Sisetshenziswa kabanzi ezimonyweni zokuvikela ilanga ezifana nama-sunscreen, okhilimu, ama-lotion, ama-emulsion, amafutha, njll., futhi singasetshenziswa njenge-ejenti yokulwa nokushintsha kombala emikhiqizweni eshintsha umbala ngenxa yokuzwela kwe-photosensitivity.
Izifutho ze-Benzophenone ultraviolet ziyiziqinisi ezinhle kakhulu zepulasitiki zokwenziwa ezifana ne-polyethylene, ezinomthamo ongu-0.5-1.5%. Zingasetshenziswa futhi epende, embaleni wemibala, embonini yokumboza, e-paraffin ehlungiwe, nasezimonyweni zansuku zonke.
Isetshenziswa kumapulasitiki, imicu yamakhemikhali, upende kanye nemikhiqizo kaphethiloli, futhi ifaneleka kakhulu emikhiqizweni enombala okhanyayo nebonakalayo.
Ingasetshenziswa kupende kanye nemikhiqizo ehlukahlukene yepulasitiki, futhi isebenza kahle kakhulu kwi-polyvinyl chloride, i-polyester, i-acrylic, i-resin, i-polystyrene, kanye nefenisha ekhanyayo ekhanyayo, njll. Futhi iyisengezo esihle kakhulu sezimonyo. Umthamo u-0.1-0.5%.
Ukupakisha Nokuthumela
