I-Absorbent ye-Ultraviolet (i-UV absorber) sisizinzi sokukhanya esinokufunxa inxalenye ye-ultraviolet yokukhanya kwelanga kunye nemithombo yokukhanya ye-fluorescent ngaphandle kokuzitshintsha. I-Absorber ye-Ultraviolet ininzi i-crystalline powder emhlophe, ukuzinza okuhle kwe-thermal, ukuzinza kweekhemikhali ezilungileyo, ezingenambala, ezingenabuthi, ezingenavumba, ezisetyenziswa ngokubanzi kwiipolymers (iiplastiki, njl.), Iingubo kunye nokunye.

Uninzi lwemibala, ngakumbi i-pigment colorants, inokudlala inqanaba elithile lokuzinzisa ukukhanya xa isetyenziswa yodwa kwiimveliso zeplastiki. Kwiimveliso zeplastiki ezinemibala yokusetyenziswa kwangaphandle kwexesha elide, ukuzinza kokukhanya kwemveliso akunakuphuculwa ngumbala wodwa. Ukusetyenziswa kuphela kwe-stabilizer yokukhanya kunokuthintela ngokufanelekileyo okanye ukucothisa izinga lokuguga elikhanyayo leemveliso zeplastiki ezinemibala ixesha elide. Ukuphucula ngokuphawulekayo ukuzinza kokukhanya kweemveliso zeplastiki ezinemibala. I-Hindered amine light stabilizer (HALS) yiklasi ye-organic amine compounds ene-steric hindrance effect. Ngenxa yemisebenzi yayo yokubola i-hydroperoxide, ukucima i-oksijini ye-radical, ukubamba i-radicals yamahhala, kunye nokuphinda kusetyenziswe amaqela asebenzayo, i-HALS yi-stabilizer yokukhanya kweplastiki kunye nokusebenza okuphezulu kwe-anti-photoaging kunye neyona mali inkulu ekhaya nakwamanye amazwe. Idatha ibonisa ukuba i-stabilizer yokukhanya efanelekileyo okanye inkqubo efanelekileyo yokudibanisa i-antioxidant kunye ne-stabilizer yokukhanya inokuphucula ukukhanya kunye nokuqina kwe-oksijini yeemveliso zeplastiki ezinemibala yangaphandle amaxesha amaninzi. Kwiimveliso zeplastiki ezinemibala yefotoactive kunye ne-photosensitive colorants (efana ne-cadmium yellow, i-rutile engafakwanga, njl.njl.), kuthathelwa ingqalelo impembelelo ye-catalytic photoaging yombala, ubungakanani bokuzinzisa ukukhanya kufuneka kwandiswe ngokufanelekileyo.

Izixhobo zokufunxa iUv zinokuhlelwa ngokubanzi ngokwesakhiwo sekhemikhali, iqhezu lesenzo kunye nokusetyenziswa, ezichazwe ngezantsi:

1.Ukuhlelwa ngokwesakhiwo sekhemikhali: i-ultraviolet absorbers ingahlulwa ibe yi-organic ultraviolet absorbers kunye ne-inorganic ultraviolet absorbers. Izinto zokufunxa i-ultraviolet zendalo ikakhulu ziquka i-benzoates, i-benzotriazole, i-cyanoacrylate, njl.

2.Ukuhlelwa ngokwendlela yokwenza: i-absorbent ye-ultraviolet inokwahlulwa ibe yintlobo yokukhusela kunye nohlobo lokufunxa. I-Absorber ye-UV ekhuselayo iyakwazi ukubonakalisa ukukhanya kwe-UV kwaye ngaloo ndlela inqande ukuba ingangeni emzimbeni, ngelixa i-Absorbeers ye-UV ikwazi ukufunxa ukukhanya kwe-UV kwaye iguqule ibe bubushushu okanye ukukhanya okubonakalayo.

3.I-Classification ngokusetyenziswa: i-absorbent ye-ultraviolet inokwahlulwa ibe yibakala lokuthambisa, ibakala lokutya, ibakala lamayeza, njl njl. I-cosmetic grade i-UV absorbers isetyenziswa kakhulu kwi-sunscreen, iimveliso zokunakekelwa kwesikhumba kunye nezinye izithambiso, ibakala lokutya i-UV absorbers isetyenziswa kakhulu ekutyeni. izinto zokupakisha, kunye ne-absorbi ye-UV yodidi lwamayeza isetyenziswa ikakhulu kumachiza.

I-Unilong Industry yingcaliUmvelisi we-UV, sinokunika oku kulandelayoUV seriesyeemveliso, ukuba ufuna, nceda uzive ukhululekile ukuba uqhagamshelane nathi
