1. Zvinhu zvakatipoteredza zvekuora
Latitude uye longitudo, tembiricha, humidity, yakazara mwaranzi (uv intensity, kupenya kwezuva), kunaya kwemvura, pH kukosha, kumhanya kwemhepo, mafambiro emhepo, corrosive sediment (C1, SO2).
2. Pesvedzero yechiedza chezuva
Chiedza chezuva ndeye electromagnetic wave, zvinoenderana nesimba uye kuwanda kwechikamu chakakamurwa kuita gamma rays, X-rays, ultraviolet, mwenje unooneka, infrared, microwave nemasaisai eredhiyo.Iyo ULTRAVIOLET spectrum (UV) ndeyeiyo yakakwira frequency radiation, iyo inoparadza zvakanyanya kupfuura yakaderera simba spectrum.Somuenzaniso, tinoziva kuti mavara akasvibira paganda negomarara reganda anokonzerwa nemwaranzi yezuva inonzi ultraviolet.UV inogona zvakare kutyora kemikari zvisungo zvechinhu, zvichiita kuti chityoke, zvichienderana nehurefu hweUV uye kusimba kwekemikari zvisungo zvechinhu.X-rays ine mhedzisiro inopinda mukati, uye gamma mwaranzi inogona kutyora makemikari bond uye kugadzira ayoni anochajiswa mahara, ayo anouraya kune organic zvinhu.
3. Kukanganisa kwekushisa uye humidity
Zvekuputira simbi, tembiricha yakakwira uye hunyoro hunobatsira mukuita oxidation (corrosion).Iyo molecular chimiro chepende pamusoro pevara coating board iri nyore kukuvadzwa kana iri munzvimbo yakakwirira yekupisa kwenguva yakareba.Kana hunyoro hwakwira, nzvimbo yacho iri nyore kuita condensation uye electrochemical corrosion maitiro inowedzerwa.
4. Kufurira kweph pakuita ngura
Kune simbi deposits (zingi kana aruminiyamu) iwo ose amphoteric simbi uye anogona corroded ne akasimba asidhi nemabhesi.Asi akasiyana simbi asidhi uye alkali kuramba kugona ane hunhu hwayo, galvanized ndiro alkaline kuramba yakasimba zvishoma, aruminiyamu zinc asidhi kuramba yakasimba zvishoma.
5. Kukanganisa kwemvura
Kudzivirirwa kwekuora kwemvura inonaya kubhodhi yakapendwa zvinoenderana nechimiro chechivako uye acidity yemvura inonaya.Kune zvivakwa zvine mutsetse wakakura (semadziro), mvura inonaya ine basa rekuzvichenesa kuitira kudzivirira kuwedzera kukoromoka, asi kana zvikamu zvacho zvikaumbwa nekadiki kadiki (sepadenga), mvura inonaya ichaisa pamusoro kwenguva refu, kusimudzira coating hydrolysis uye kupinda mvura.Kune majoini kana kuchekwa kwemahwendefa esimbi, kuvepo kwemvura kunowedzera mukana wekuti electrochemical corrosion, kutaridzika kwakakoshawo, uye mvura yeasidhi yakanyanya kuoma.
