Izici zemvelo ezithinta amaphaneli anemibala
Njengoba sibhekene nezinhlobonhlobo zezinhlobo zokumboza, kufanele sikhethe kanjani?Ake ngethule izici eziningana zemvelo ezithinta ukusetshenziswa kwamabhodi anemibala.
1. Izinga lokushisa
Ukugqoka kulula ukuthambisa ekushiseni okuphezulu, futhi i-corrosive medium kulula ukunamathela.Kulula ukungena ku-substrate, okuqukethwe kwe-oksijeni emanzini kuzokwanda ekushiseni okuphezulu, futhi izinga lokugqwala lizokwanda ekushiseni okuthile.
2. Umswakama
Ukugqwala kwe-substrate ekulimaleni okusikiwe nokucutshungulwa kwebhodi elihlanganiswe ngombala kungokwe-electrochemical corrosion, futhi umswakama ophansi akulula ukwakha ibhethri lokugqwala (okungukuthi isekethe ye-electrochemical).
3, Umehluko wokushisa phakathi kwemini nobusuku
Umehluko omkhulu wokushisa kulula ukujiya, wenze isimo sokugqwala kwe-galvanic ensimbi engenalutho.Ngaphezu kwalokho, umehluko omkhulu wokushisa ubuye uholele ekuguqukeni okubandayo nokushisa okujwayelekile kwe-coating, okuzosheshisa ukuguga nokuxega kwe-coating, futhi i-corrosive medium yangaphandle izongena kalula ku-substrate.
4. Isikhathi sokukhanya kwelanga namandla
Ukuma nokuthambeka kuthinta ubude besikhathi sokukhanya kwelanga kanjalo nokuqina kwento enamathelayo.I-slope iphinde ithinte isikhathi sokumisa semidiya ebolayo noma uthuli ku-steel plate.Ukukhanya kwelanga amaza kagesi, ahlukaniswe abe imisebe ye-gamma, i-X-ray, imisebe ye-ultraviolet, ukukhanya okubonakalayo, imisebe ye-infrared, ama-microwave namaza omsakazo ngokwamandla awo kanye nemvamisa.Amaza namaza omsakazo anamandla aphansi futhi awahlangani nendaba.I-infrared nayo iyi-spectrum yamandla aphansi.Ingakwazi ukwelula noma ukugoba kuphela izibopho zamakhemikhali zezinto, kodwa ayikwazi ukuzigqashula.Ukukhanya okubonakalayo kunikeza yonke into imibala ecebile.I-spectrum ye-UV iyimisebe ye-high-frequency, enamandla amakhulu okubhubhisa kune-spectrum yamandla aphansi.Njengoba sazi, amabala amnyama esikhumbeni kanye nomdlavuza wesikhumba kubangelwa imisebe yelanga ye-ultraviolet.Ngokufanayo, i-UV ingakwazi futhi ukunqamula izibopho zamakhemikhali zezinto, zibangele ukuba zigqabuke.Lokhu kuncike kubude beza be-UV namandla esibopho samakhemikhali ento.Ama-X-ray anemiphumela engena.Imisebe ye-Gamma inganqamula izibopho zamakhemikhali zezinto futhi ikhiqize ama-ion ashajwa mahhala.Lezi ziyingozi ezintweni eziphilayo.Ngenhlanhla, le misebe mincane kakhulu ekukhanyeni kwelanga.Ngakho-ke, kubonakala kulokhu okungenhla ukuthi isikhathi sokukhanya kwelanga nokuqina kuthinta ukuzinza kwesakhiwo sokumboza, ikakhulukazi ezindaweni ezinemisebe ye-ultraviolet enamandla.
5. Imvula kanye ne-acidity
I-acidity yemvula ngokungangabazeki iyingozi ekumelaneni nokugqwala.Nokho, imvula inomphumela okabili.Kumapulangwe odonga namaphaneli ophahla anemithambeka emikhulu, imvula ingahlanza ingaphezulu lamapuleti ensimbi futhi igeze imikhiqizo yokugqwala.Kodwa-ke, kumapulangwe ophahleni anemithambeka ephansi kanye nezindawo ezine-drainage empofu, imvula enkulu izoba Kulula ukwenza ukugqwala kukhuphuke.
6. Isiqondiso somoya nesivinini
Umphumela wokuqondisa komoya kanye nesivinini somoya ufana nowamanzi, futhi avame ukuhambisana.Kuyisivivinyo sokuxhunywa kwezinto, ngoba umoya uzokwenza ukuthi uxhumano lukhululeke futhi amanzi emvula azongena ngaphakathi kwesakhiwo.
7. Ukugqwala kanye nenhlabathi
Isibonelo, ama-ion e-chloride, i-sulphur dioxide, njll. anomthelela wokusheshisa ukugqwala, futhi lezi zinsalela ngokuvamile zenzeka ngasogwini lolwandle nasezindaweni ezinokungcola okukhulu kwezimboni (njengezitshalo zikagesi, izincibilikisi, njll.).
