Ukusetyenziswa
I-ultraviolet absorber UV-9 yi-crystalline powder etyheli okanye emhlophe ekhanyayo, eyaziwa ngokuba yi-Sunscreen Agent No. 2 kunye ne-BP-3. Ifanelekile kwiiplastiki ezahlukeneyo ezifana ne-polyvinyl chloride, i-polyvinylidene chloride, i-polymethyl methacrylate, i-unsaturated polyester, i-ABS resin, kunye ne-cellulose resin. Uluhlu lwayo oluphezulu lwe-absorption wavelength yi-280-340 nanometers, kunye nomthamo oqhelekileyo we-0.1-1.5%. Izinzile kakuhle kubushushu kwaye ayiboli kwi-200°C. Le mveliso ayifunxi ukukhanya okubonakalayo, ngoko ke ifanelekile kwiimveliso ezinombala okhanyayo nezicacileyo. Ingasetyenziswa nakwiipeyinti kunye nerabha yokwenziwa. Njenge-broad-spectrum ultraviolet absorber evela kwi-Chemicalbook, ineenzuzo zesantya esiphezulu sokufunxa, ukungabi natyhefu, ukungabikho kwe-teratogenic effect, kunye nokuzinza okuhle ekukhanyeni nasekufudumaleni. I-ultraviolet absorber UV-9 inokufunxa zombini i-UV-A kunye ne-UV-B. Yi-sunscreen yeClass Ⅰ evunyiweyo yi-US FDA, kwaye isetyenziswa rhoqo e-United States nakwamanye amazwe aseYurophu. I-UV-9 isetyenziswa kakhulu kwizinto zokuthambisa ezikhusela ilanga ezifana neekhrimu zelanga, iiloshini, ubisi, iiemulsion, kunye neeoyile. Ingasetyenziswa njengearhente yokulwa nokutshintsha kombala kwiimveliso ezitshintsha umbala ngenxa yokungaziva mnandi. Ukongeza, ngenxa yokuhambelana kwayo kakuhle neeplastiki ezininzi kunye neeresini, idla ngokusetyenziswa kwiindawo ezininzi ezifana ne-PVC kunye ne-polyester engagcwaliyo.
Isithambisi se-UV i-UV-9 sisithambisi se-UV esineenzuzo ezininzi ezifana nesantya esiphezulu sokufunxa, ukungabi natyhefu, akukho mpembelelo ye-teratogenic, kunye nokuzinza okuhle ekukhanyeni nasekufudumaleni. Singakwazi ukufunxa zombini i-UV-A kunye ne-UV-B. Sisithambisi selanga seKlasi Ⅰ esivunyiweyo yi-US FDA, kwaye sisetyenziswa rhoqo eMelika naseYurophu. Sisetyenziswa kakhulu kwizithambisi zokukhusela ilanga ezifana nezithambisi zelanga, iikhrimu, iiloshini, ii-emulsions, iioyile, njl.njl., kwaye singasetyenziswa njengearhente yokulwa nokutshintsha kombala kwiimveliso ezitshintsha umbala ngenxa yokungaziva kakuhle kwe-photosensitivity.
Izifunxi ze-Benzophenone ultraviolet zizinto ezizinzisa kakuhle iiplastiki zokwenziwa ezifana ne-polyethylene, ezinomlinganiselo we-0.5-1.5%. Zingasetyenziswa nakwipeyinti, i-pigment, ishishini lokugquma, iparafini ecociweyo, kunye nezimonyo zemihla ngemihla.
Isetyenziswa kwiiplastiki, kwiifayibha zeekhemikhali, kwiipeyinti nakwiimveliso zepetroleum, kwaye ifanelekile ngakumbi kwiimveliso ezinombala okhanyayo nezibonakalayo.
Ingasetyenziswa kwiipeyinti nakwiimveliso ezahlukeneyo zeplastiki, kwaye isebenza ngakumbi kwi-polyvinyl chloride, i-polyester, i-acrylic, i-resin, i-polystyrene, kunye nefenitshala ekhanyayo ekhanyayo, njl. Ikwayisongezo esihle kakhulu sobuhle. Umlinganiselo yi-0.1-0.5%.
