Mavhitaminzi eUV, anozivikanwawo semafirita eUV kana mafirita ezuva, makomisheni anoshandiswa kuchengetedza zvinhu zvakasiyana-siyana kubva pakukuvadza kwemwaranzi yeultraviolet (UV). Imwe yakadaro UV absorber ndeye UV234, inova sarudzo yakakurumbira yekupa dziviriro kubva kune UV mwaranzi. Muchinyorwa chino tichaongorora huwandu hwemaUV absorbers uye tiongorore mune chaiyo zvivakwa uye mashandisiro eUV234.

Iyo spectrum yeUV absorbers inovhara huwandu hwakasiyana hwemakomisheni akagadzirirwa kutora uye kubvisa UV mwaranzi. Mishonga iyi inowanzoshandiswa muzvigadzirwa zvakaita sezuva, mapurasitiki, pendi uye machira kudzivirira kuparara uye kukuvadzwa kunokonzerwa nekuratidzwa kweUV. UV maabsorbir anoshanda nekutora mwaranzi yeUV uye nekuishandura kuita kupisa kusingakuvadzi, nekudaro ichidzivirira zvinhu kubva kune zvinokuvadza zvemwaranzi yeUV.

UV absorbers yakakamurwa kuva mapoka akasiyana zvichienderana nemakemikari avo uye maitiro ekuita. Mamwe marudzi akajairika ezvinwiwa zveUV anosanganisira benzophenones, benzotriazoles, uye triazines. Mhando yega yega yeUV inonyudza ine mabhenefiti chaiwo uye akakodzera kune akasiyana maapplication. Semuenzaniso, UV234 ndeye benzotriazole UV absorber iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kweiyo yakanakisa yekudzivirira UV yekudzivirira.

UV234 inozivikanwa nekushanda kwayo kwepamusoro mukutora ultraviolet mwaranzi, kunyanya muUVB neUVA renji. Izvi zvinoita kuti ive yakanakira kupa yakafara-spectrum UV kuchengetedzwa kwemwaranzi. UV234 inowanzo shandiswa mukugadzira sunscreen kusimudzira chigadzirwa cheUV kuchengetedza kugona. Pamusoro pezvo, inoshandiswa mumapurasitiki uye machira kudzivirira kuomeswa kwemifananidzo uye kuchengetedza kutendeseka kwechinhu kana ichinge yavhenekwa nezuva.

Zvishandiso zveUV234hazvigumiri kune sunscreen uye machira ekudzivirira. Inoshandiswawo muindasitiri yemachira kupa UV kuramba kune machira uye fiber. Nekubatanidza UV234 mumachira, vagadziri vanogona kuwedzera kusimba uye hupenyu hurefu hwezvinhu, zvichiita kuti ive yakakodzera kune zvekunze kunyorera uko kuratidzwa kune UV mwaranzi isingadzivisike.

Pamusoro peiyo UV-inobata zvivakwa, UV234 inozivikanwa zvakare nekugona kwayo kutaridzika, iyo inova nechokwadi chekuti inoramba ichishanda kunyangwe mushure mekuratidzwa kwenguva refu kuzuva. Ichi chivakwa chakakosha kuchengetedza kushanda kwezvigadzirwa zvine UV234, sezvo ichichengetedza kuchengetedzwa kwenguva refu kubva kune UV mwaranzi.

Paunenge uchifunga nezve huwandu hwemaUV absorbers, zvakakosha kuti unzwisise izvo chaizvo zvinodikanwa zvekushandisa uye nhanho yekudzivirira kweUV inodiwa. Yakasiyana UV inonyudza inopa akasiyana madhigirii eUV dziviriro uye kuenderana nezvinhu zvakasiyana. Nokudaro, zvakakosha kusarudza zvakakodzeraUV absorberzvichibva pachinangwa chekushandiswa uye chaiwo maficha echinhu chiri kuchengetedzwa.

Muchidimbu, zvinobatisa UV zvinoita basa rakakosha mukudzivirira zvinhu kubva mukukuvadza mwaranzi yeUV. UV234 ndeye benzotriazole UV absorber iyo inoshandiswa zvakanyanya kune yayo yakanakisa UV yekudzivirira zvimiro uye mafoto. Kunzwisisa huwandu hwemaAbsorbir eUV uye zvimiro zvawo zvakakosha kuti usarudze iyo yakanyanya kukodzera UV yekunyudza kune chaiyo application. Zvingave mukugadzirwa kwezuva, mapurasitiki, machira kana machira, maAbsorbing eUV akadai seUV234 anopa dziviriro yakavimbika kubva kumwaranzi yeUV, zvichibatsira kuwedzera hupenyu uye kushanda kwezvakasiyana zvinhu.
