1. Izici zemvelo zokugqwala
I-latitude nobude, izinga lokushisa, umswakama, imisebe isiyonke (amandla e-uv, ubude belanga), imvula, inani le-pH, isivinini somoya, isiqondiso somoya, i-corrosive sediment (C1, SO2).
2. Ithonya lokukhanya kwelanga
Ukukhanya kwelanga kuyigagasi kagesi, ngokwamandla kanye nemvamisa yezinga lihlukaniswe ngemisebe ye-gamma, imisebe ye-X, i-ultraviolet, ukukhanya okubonakalayo, i-infrared, i-microwave namaza omsakazo.I-ULTRAVIOLET spectrum (UV) ingeye-high frequency radiation, eyingozi kakhulu kune-spectrum yamandla aphansi.Ngokwesibonelo, siyazi ukuthi amabala amnyama esikhumbeni nasemdlavuzeni wesikhumba abangelwa imisebe yelanga e-ultraviolet.I-UV ingase futhi inqamule izibopho zamakhemikhali zento, ibangele ukuba inqamuke, kuye ngobude begagasi be-UV namandla amabhondi amakhemikhali ento.Ama-X-ray anomphumela ongenelayo, futhi imisebe ye-gamma inganqamula izibopho zamakhemikhali futhi ikhiqize ama-ion ashajwa mahhala, abulalayo ezintweni eziphilayo.
3. Umthelela wezinga lokushisa nomswakama
Ngezingubo zensimbi, izinga lokushisa eliphezulu kanye nomswakama kunomthelela ekuphenduleni kwe-oxidation (ukugqwala).Isakhiwo se-molecular of paint on the surface of color coating board kulula ukonakala lapho sisendaweni yokushisa ephezulu isikhathi eside.Uma umswakamo uphezulu, kulula ukujiya ingaphezulu futhi ukugqwala kwe-electrochemical kuyathuthukiswa.
4. Umthelela we-ph ekusebenzeni kokugqwala
Kumadiphozithi ensimbi (zinc noma i-aluminium) zonke ziyizinsimbi ze-amphoteric futhi zingagqwala ngama-asidi aqinile nezisekelo.Kodwa i-asidi yensimbi ehlukene kanye nekhono lokumelana ne-alkali linezici zalo, ukumelana ne-alkaline plate kunamandla kancane, ukumelana ne-aluminium zinc acid kunamandla kancane.
5. Umthelela wemvula
Ukumelana nokugqwala kwamanzi emvula ebhodini elipendiwe kuncike esakhiweni sesakhiwo kanye ne-acidity yamanzi emvula.Emabhilidini anothambeka olukhulu (njengezindonga), amanzi emvula anomsebenzi wokuzihlanza ukuze agweme ukugqwala okuqhubekayo, kodwa uma izingxenye zibunjwa ngomthambeka omncane (njengokufulela), amanzi emvula azobeka phezulu isikhathi eside, ukukhuthaza i-coating hydrolysis kanye nokungena kwamanzi.Kumalunga noma ukusikeka kwamapuleti ensimbi, ukuba khona kwamanzi kwandisa amathuba okugqwala kwe-electrochemical, ukuma nakho kubaluleke kakhulu, futhi imvula ene-asidi iyingozi kakhulu.
