Ultraviolet absorber (UV absorber) inodzikamisa mwenje inokwanisa kutora ultraviolet chikamu chechiedza chezuva uye fluorescent mwenje masosi pasina kuzvishandura.Ultraviolet absorber inonyanya kuchena crystalline poda, kugadzikana kwakanaka kwekupisa, kugadzikana kwakanaka kwemakemikari, isina ruvara, isina chepfu, isina kunhuhwirira, inowanzoshandiswa mumapolymers (mapurasitiki, nezvimwewo), machira uye zvichingodaro.

Mazhinji colorants, kunyanya inorganic pigment colorants, anogona kutamba imwe dhigirii yekudzikamisa mwenje kana ichishandiswa yega muzvigadzirwa zvepurasitiki.Kune zvigadzirwa zvepurasitiki zvemavara zvekushandisa kwenguva refu kunze, kugadzikana kwechiedza chechigadzirwa hakugone kuvandudzwa nemuvara wega.Chete kushandiswa kwechiedza stabilizer kunogona kunyatso kuvharidzira kana kuderedza kuchembera kwechiedza chezvigadzirwa zvepurasitiki zvine mavara kwenguva yakareba.Zvinonyanya kuvandudza kugadzikana kwechiedza chemavara epurasitiki zvigadzirwa.Hindered amine light stabilizer (HALS) ikirasi yema organic amine makomisheni ane steric hindrance effect.Nekuda kwemabasa ayo ekuora hydroperoxide, kudzima radical oxygen, kuteya mahara radicals, uye kudzokorodza kwemapoka anoshanda, HALS ndiyo yepurasitiki light stabilizer ine yakakwira anti-photoaging uye yakawanda kwazvo kumba nekune dzimwe nyika.Iyo data inoratidza kuti iyo yakakodzera mwenje stabilizer kana yakakodzera musanganiswa system ye antioxidant uye light stabilizer inogona kuvandudza kujeka uye kugadzikana kweokisijeni yekunze kwemavara epurasitiki zvigadzirwa kakati wandei.Kune zvigadzirwa zvepurasitiki zvine mavara ane mafotoactive uye photosensitive colorants (senge cadmium yero, isina uncored rutile, nezvimwewo), tichifunga nezve catalytic photoaging mhedzisiro yeruvara, huwandu hwemwenje stabilizer hunofanira kuwedzerwa zvinoenderana.

Uv absorbers inogona kurongeka zvichienderana nemakemikari chimiro, chidimbu chekuita uye kushandiswa, izvo zvinotsanangurwa pazasi:

1.Kuronga maererano nemakemikari maitiro: ultraviolet absorbers inogona kugoverwa kuva organic ultraviolet absorbers uye inorganic ultraviolet absorbers.Organic ultraviolet absorbers inonyanya kusanganisira benzoates, benzotriazole, cyanoacrylate, nezvimwewo, nepo inorganic ultraviolet absorbers kunyanya zvinosanganisira zinc oxide, iron oxide, titanium dioxide zvichingodaro.

2.Kuronga maererano nemaitiro ekuita: ultraviolet absorber inogona kugoverwa kuva shielding type uye absorption type.Shielding UV inopinza inokwanisa kuratidza UV mwenje uye nekudaro ichidzivirira kuti isapinda mumuviri, nepo ichitora UV maabsorbir inokwanisa kutora UV mwenje nekuishandura kuita kupisa kana mwenje unooneka.

3.Kuronga maererano nekushandiswa: ultraviolet absorbent inogona kugoverwa mugiredhi yekuzora, giredhi rekudya, giredhi remishonga, etc. Cosmetic giredhi UV absorbers inonyanya kushandiswa muzuva, ganda rekuchengetedza zvigadzirwa uye zvimwe zvizoro, chikafu giredhi UV absorbers inonyanya kushandiswa mukudya. kurongedza zvinhu, uye mishonga giredhi UV inonyudza inonyanya kushandiswa mumishonga.

Unilong Industry inyanzviUV mugadziri, tinogona kupa zvinoteveraUV serieszvezvigadzirwa, kana uchida, ndapota inzwa wakasununguka kutibata nesu
