Tichitaura nezvemazwi emakemikari ehunyanzvi akadai seUV absorbers uye photostabilizers, vanhu vazhinji vangasaziva zvavari, asi kana maAbsorbirs eUV akawedzerwa kune sunscreen, anogona kudzivirira ganda redu kubva pakupiswa nezuva rinopisa, Kupisa kwezuva, vanhu vazhinji vanogona kuerekana vaona kuti UV inonyudza chii uye kuti chii. Muchokwadi, ma ultraviolet absorbers uye light stabilizers anowedzerwa muhuwandu mune organic zvinhu zvigadzirwa zvatinoshandisa mazuva ese, asi iwe hauzvizive. Pendi iri kunze kwemotokari yemhuri yatinotyaira inowanzowedzerwa papende. Inogona kudzivirira ruvara rwemotokari kubva kune yero, kupera, uye kurasikirwa kwechiedza. Mamwe maAbsorbir eUV ane akakosha zvimiro anozowedzerwa kune yekutanga layer yeoptical firimu, iyo inogona kuvharira inokuvadza ultraviolet mwaranzi kudzivirira maziso edu kubva mukukuvadzwa ...
Sezvo zvinotora UV uye zvigadziriso zvemwenje zvichishandiswa zvakanyanya uye zvine mhedzisiro yakakura kudaro, ndeupi musiyano uripo pakati pazvo?
Ese ari maviri maAbsorber eUV uye magadziriso emwenje akakosha emakemikari ekuwedzera kuchengetedza nekuchengetedza kuita kweorganic zvinhu, asi pane mimwe misiyano mumabasa avo. Iyo ultraviolet absorber inogona kushandura inokuvadza ultraviolet mwaranzi kuburikidza neyayo yakakosha chimiro chemakemikari, kushandura inokuvadza ultraviolet inoparadza simba kuita isingakuvadze kupisa simba uye kuisunungura, uye kudzivirira iyo yakakwira simba reultraviolet mwaranzi kubva pakupwanya mamorekuru ezve organic zvinhu, nekudaro kurasikirwa nemapolima. Zvinhu izvo zvinhu zvinofanira kuva nazvo; uye iyo inosimbisa mwenje inogona kunzwisiswa semusevha weanokuvadza emahara radicals. Kamwe kamwe mwenje we ultraviolet anotyora nekudzivirira kweiyo ultraviolet inonyudza uye kutyora ma molecular chain of the organic material, ichiita inokuvadza polymer free radicals, light stabilizer Zvinogoneka kutora panguva inokuvadza mahara radicals mune isingakuvadzi yakagadzikana madiki mamorekuru zvimiro. Kazhinji vanhu vanozowedzera zvinobatisa UV uye zvigadziriso zvemwenje kune organic zvinhu mune imwe chikamu, uye kuita kwayo kwekudzivirira kunowanzo kuve nani pane kuya kweUV absorbers kana mwenje stabilizer chete.
Ultraviolet absorbers uye light stabilizers ndiwo mazita akaunganidzwa emhando mbiri dzezvigadzirwa, uye kune akawanda akasiyana marudzi pasi pawo, achigadzira yakakura maindasitiri system. Mhando dzakajairwa dzemaUV anonwisa pamusika dzinosanganisira benzophenones, benzotriazoles, triazines, nezvimwewo, zvakasiyana maererano neUV shielding performance uye maindasitiri ekushandisa; light stabilizers zvakare izwi rakajairika, uye indasitiri Kazhinji zvinoenderana neakasiyana madhigirii ealkalinity, hunhu hwakawanda hunogadzirwa, uye kune zvakare misiyano yehupfu uye mvura pakuonekwa.
