Cosmetic kurongedza zvinhu zvakanyanya mapurasitiki, girazi uye bepa. Munguva yekushandiswa, kugadzirisa uye kuchengetedza mapurasitiki, nekuda kwezvakasiyana zvekunze zvinhu zvakaita sechiedza, okisijeni, kupisa, mwaranzi, kunhuwa, mvura, mold, mabhakitiriya, nezvimwewo, chimiro chemakemikari emapurasitiki chinoparadzwa, zvichikonzera kurasikirwa kwavo. yepakutanga yakanakisa zvivakwa. Chiitiko ichi chinowanzonzi kuchembera. Chiratidzo chikuru chekuchembera kwepurasitiki kushanduka kwemavara, kushanduka kwemaitiro emuviri, shanduko yemagetsi emagetsi uye shanduko yemagetsi zvinhu.
1. Mhedziso yekukwegura kwepurasitiki
Muhupenyu hwedu, zvimwe zvigadzirwa zvinovhenekerwa nechiedza, uye iyo ultraviolet mwenje muchiedza chezuva, pamwe nekupisa kwakanyanya, mvura nedova, zvinokonzeresa kuti chigadzirwa chisangane nezviitiko zvekuchembera zvakaita sekurasikirwa kwesimba, kuputika, kusvuura, kusasimba, kushanduka, uye upfu. Chiedza chezuva uye hunyoro ndizvo zvinhu zvikuru zvinokonzera kukwegura kwezvinhu. Chiedza chezuva chinogona kukonzera kuti zvinhu zvakawanda zvidzikire, izvo zvine chekuita nekunzwa uye spectrum yezvinhu. Chinhu chimwe nechimwe chinopindura zvakasiyana kune spectrum.
Zvinhu zvinonyanya kuchembera zvemapurasitiki munzvimbo yakasikwa kupisa uye ultraviolet mwenje, nekuti nharaunda iyo zvinhu zvepurasitiki zvinonyanya kuratidzwa kupisa uye chiedza chezuva (ultraviolet light). Kudzidza kuchembera kwepurasitiki kunokonzerwa nemhando mbiri idzi dzenzvimbo kwakakosha zvakanyanya kune chaiyo yekushandisa nharaunda. Muedzo wayo wekuchembera unogona kukamurwa kuita zvikamu zviviri: kuratidzwa kwekunze uye marabhoritari inomhanyisa bvunzo yekuchembera.
Chigadzirwa chisati chaiswa mukushandiswa kwakakura, kuyedza kuchembera kunofanirwa kuitwa kuti iongorore kuramba kwayo kuchembera. Zvisinei, kuchembera kwomuzvarirwo kunogona kutora makore akati kuti kana kuti kunyange kureba kuti uone miuyo, izvo zviri pachena kuti hazvienderani nekugadzirwa chaiko. Uyezve, mamiriro ekunze munzvimbo dzakasiyana akasiyana. Iyo yakafanana bvunzo zvinhu zvinoda kuongororwa munzvimbo dzakasiyana, izvo zvinowedzera zvakanyanya mutengo wekuyedza.
2. Outdoor exposure test
Kunze kwakananga kuratidzwa kunoreva kuratidzwa zvakananga kuchiedza chezuva nemamwe mamiriro ekunze. Ndiyo nzira yakananga yekuongorora kupikisa kwemamiriro ekunze kwezvinhu zvepurasitiki.
Zvakanakira:
Mutengo wakaderera
Kuenderana kwakanaka
Nyore uye nyore kushanda
Zvakaipa:
Kazhinji refu refu kutenderera
Kusiyana kwemamiriro ekunze pasi rose
Mienzaniso yakasiyana ine manzwiro akasiyana mumamiriro ekunze akasiyana
3. Murabhoritari yakamhanyisa nzira yekuyedza kuchembera
Laboratory mwenje kuchembera bvunzo haingopfupiki kutenderera, asi zvakare ine yakanaka kudzokorora uye yakakura application renji. Inopedzwa murabhoritari mukati mekuita, pasina kufunga nezvezvirambidzo zvenzvimbo, uye iri nyore kushanda uye ine controllability yakasimba. Kutevedzera nharaunda chaiyo yekuvhenekesa uye kushandisa yekugadzira inomhanyisa chiedza kuchembera nzira dzinogona kuzadzisa chinangwa chekukurumidza kuongorora kushanda kwezvinhu. Nzira huru dzinoshandiswa ndeye ultraviolet mwenje kuchembera bvunzo, xenon mwenje kuchembera bvunzo uye kabhoni arc mwenje kuchembera.
1. Xenon chiedza kuchembera bvunzo nzira
Xenon mwenje kuchembera bvunzo bvunzo inoteedzera kuzara kwezuva spectrum. Xenon mwenje kuchembera bvunzo inogona kutevedzera yakasikwa yemamiriro ekunze munguva pfupi. Iyo inzira yakakosha yekutarisa mafomula uye kukwenenzvera kuumbwa kwechigadzirwa mukuita kwekutsvaga kwesainzi nekugadzira, uye zvakare chikamu chakakosha chekuongorora kwemhando yechigadzirwa.
Xenon mwenje kuchembera bvunzo data inogona kubatsira kusarudza zvinhu zvitsva, kushandura zvinhu zviripo, uye kuongorora kuti shanduko yemafomati inokanganisa sei kusimba kwezvigadzirwa.
Nheyo yakakosha: Iyo xenon mwenje yekamuri yekuyedza inoshandisa mwenje xenon kutevedzera mhedzisiro yechiedza chezuva, uye inoshandisa mwando wakafukidzwa kutevedzera mvura nedova. Iyo yakaedzwa zvinhu inoiswa mudenderedzwa rekuchinjanisa mwenje uye hunyoro pane imwe tembiricha yekuyedza, uye inogona kuburitsa njodzi dzinoitika kunze kwemwedzi kana makore mumazuva mashoma kana mavhiki.
Test application:
Inogona kupa inoenderana kwezvakatipoteredza simulation uye yakakurumidza bvunzo yekutsvagisa kwesainzi, kusimudzira chigadzirwa uye kutonga kwemhando.
Inogona kushandiswa pakusarudzwa kwezvinhu zvitsva, kuvandudzwa kwezvinhu zviripo kana kuongorora kusimba mushure mekuchinja kwekuumbwa kwezvinhu.
Inogona kunyatso kutevedzera shanduko dzinokonzerwa nezvinhu zvakafumurwa kuchiedza chezuva pasi pemamiriro akasiyana ezvakatipoteredza.
2. UV fluorescent chiedza kukwegura bvunzo nzira
Iyo UV yekuchembera bvunzo inonyanya kutevedzera kushatisa mhedzisiro yeUV mwenje muchiedza chezuva pachigadzirwa. Panguva imwecheteyo, inogonawo kubereka kukanganisa kunokonzerwa nemvura nedova. Muedzo unoitwa nekufumura zvinhu kuti zviongororwe mune inodzorwa inopindirana kutenderera kwezuva uye hunyoro uchiwedzera tembiricha. Mwenje weUltraviolet fluorescent anoshandiswa kutevedzera chiedza chezuva, uye pesvedzero yehunyoro inogonawo kutevedzerwa nekukonyesa kana kupfapfaidza.
Iyo fluorescent UV mwenje ndeye yakaderera-kudzvanywa mercury rambi ine wavelength ye254nm. Nekuda kwekuwedzera kwephosphorous kugarisana kuti ishanduke kuita wavelength yakareba, kugovera kwesimba kwemwenje wefluorescent UV kunoenderana nekubuda kwemhepo kunogadzirwa nekugarisana kwephosphorus uye kupararira kwechubhu yegirazi. Marambi eFluorescent anowanzo kukamurwa kuita UVA neUVB. Iyo yekushandisa exposure application inosarudza rudzi rwemwenje weUV unofanirwa kushandiswa.
3. Carbon arc rambi mwenje kuchembera bvunzo nzira
Carbon arc mwenje ndiyo yekare tekinoroji. Carbon arc chiridzwa chakatanga kushandiswa nemaGerman synthetic dhayi chemist kuongorora kukurumidza kwemwenje wemachira akadhayiwa. Carbon arc marambi akakamurwa kuita akavharwa uye akavhurika kabhoni arc marambi. Pasinei nerudzi rwekabhoni arc rambi, spectrum yaro yakasiyana chaizvo neyakajeka yezuva. Nekuda kwenhoroondo refu yeiyi tekinoroji tekinoroji, tekinoroji yekutanga yekunyepedzera kuchembera yakashandisa chishandiso ichi, saka nzira iyi inogona kuramba ichionekwa mumiyero yekutanga, kunyanya mukutanga kweJapan, uko kabhoni arc mwenje tekinoroji yaiwanzo shandiswa sechiedza chekugadzira. kuchembera bvunzo nzira.
