Chinonyungudutsa chiedza cheUltraviolet (chinonyungudutsa chiedza cheUV) chinhu chinogadzirisa chiedza chinogona kunyungudutsa chiedza chezuva cheultraviolet uye chiedza chefluorescent pasina kuchinja. Chinonyungudutsa chiedza cheUltraviolet chinowanzova upfu hwemakristalline machena, kugadzikana kwakanaka kwekupisa, kugadzikana kwakanaka kwemakemikari, kusina ruvara, kusina chepfu, hakuna hwema, chinowanzoshandiswa mumapolymers (mapurasitiki, nezvimwewo), machira nezvimwewo.
Zvizhinji zvezvipenyu zvinopenya, kunyanya zvinopenya zvisina kuchena, zvinogona kuita kuti chiedza chigadzikane kana zvikashandiswa zvega muzvigadzirwa zvepurasitiki. Pazvigadzirwa zvepurasitiki zvine mavara kuti zvishandiswe panze kwenguva refu, kugadzikana kwechiedza kwechigadzirwa hakugone kuvandudzwa nezvinopenya chete. Kushandiswa kwezvipenyu zvinopenya chete ndiko kunogona kudzivirira kana kuderedza kukwegura kwechiedza chezvigadzirwa zvepurasitiki zvine mavara kwenguva yakareba. Kuvandudza zvakanyanya kugadzikana kwechiedza chezvigadzirwa zvepurasitiki zvine mavara. Zvipenyu zvinodzivirira chiedza (HALS) iboka remakemikari e-organic amine ane steric inhibition effect. Nekuda kwebasa rayo rekuora hydroperoxide, kudzima okisijeni, kubata ma free radicals, uye kudzokorodza mapoka anoshanda, HALS ndiyo inochengetedza chiedza chepurasitiki ine simba guru rekudzivirira kutora mifananidzo uye yakawanda kwazvo kumba nekune dzimwe nyika. Data rinoratidza kuti inochengetedza chiedza chakakodzera kana system yakakodzera yekubatanidza antioxidant uye inochengetedza chiedza inogona kuvandudza kugadzikana kwechiedza neokisijeni kwezvigadzirwa zvepurasitiki zvine mavara ekunze kakawanda. Pazvinhu zvepurasitiki zvakapendwa nemavara anopenya uye anonzwa chiedza (senge cadmium yellow, uncored rutile, nezvimwewo), tichifunga nezve catalytic photoaging effect yemavara, huwandu hwechiedza chinodzikamisa chiedza hunofanira kuwedzerwa zvinoenderana.
Zvinwiwa zveUV zvinogona kupatsanurwa zvichienderana nechimiro chemakemikari, chikamu chechiito uye mashandisirwo azvo, izvo zvinotsanangurwa pazasi:
1. Kupatsanura zvichienderana nechimiro chemakemikari: zvinonyudza ultraviolet zvinogona kukamurwa kuita zvinonyudza ultraviolet zveorganic uye zvinonyudza ultraviolet zveinorganic. Zvinonyudza ultraviolet zveorganic zvinosanganisira benzoates, benzotriazole, cyanoacrylate, nezvimwewo, nepo zvinonyudza ultraviolet zveinorganic zvinosanganisira zinc oxide, iron oxide, titanium dioxide nezvimwewo.
2. Kupatsanura zvichienderana nemaitiro ekushanda: ultraviolet absorber inogona kukamurwa kuita mhando yekudzivirira uye mhando yekudzivirira. Zvishandiso zvekudzivirira UV zvinokwanisa kuratidza chiedza cheUV nokudaro zvichidzivirira kuti chisapinde mumuviri, ukuwo zvinoshandisa UV absorbers zvinokwanisa kupinza chiedza cheUV uye kuchishandura kuita kupisa kana chiedza chinoonekwa.
3. Kupatsanura zvichienderana nekushandiswa: chinodzivirira ultraviolet chinogona kukamurwa kuita giredhi rekushongedza, giredhi rechikafu, giredhi remishonga, nezvimwewo. Zvinodzivirira ganda reUV zvemhando yekushongedza zvinonyanya kushandiswa mukuchengetedza zuva, zvigadzirwa zvekuchengetedza ganda nezvimwe zvekuzora, zvinodzivirira ganda remhando yekushongedza chikafu zvinonyanya kushandiswa muzvinhu zvekurongedza chikafu, uye zvinodzivirira ganda remhando yekushongedza mishonga zvinonyanya kushandiswa mumishonga.
