Ukugqwala kuyinkinga yaphakade ejwayelene nabo bonke abanikazi bezimoto nalabo ababukele ikhaya labo. Hhayi nje kuphela izinsimbi, njengoba nje, kepha ama-alloys awo ahlukahlukene avezwa kule nqubo eyingozi. Ngenxa yezenzo zesimo sezulu sendawo, ukugqwala empeleni kungawuqeda umkhiqizo wensimbi. Lokhu kugcwele izinkinga ezinkulu.
QAPHELA: Kungani udinga ukuvikelwa
Kugcwele ngemiphumela emibi.
Imiphumela yokugqwala ingahle ibe nemiphumela emide. Uma inqubo yokugqwala iqala, khona-ke ngenyanga ngayinye nonyaka izoba nokuchaza okuningi kuphela. Ngenxa yalokhu, ukugqwala kungadala ukuncishiswa kwezinhlaka zensimbi, ukungcoliswa kwemikhiqizo, imishini yokuhoxisa kanye nezindlela, izimvume, futhi okubaluleke kakhulu - ukulahleka okukhulu kwezezimali.
Ukuze konke lokhu kungenzeki, ngidinga ukuvikelwa ekugqwalweni.
1. Izimbobo ze-anticorrosion
Ukuvikelwa kubaluleke kakhulu.
Lapho ukhetha ithuluzi, kufanele likhunjulwe ukuthi kufanele libe nezinga eliphakeme lokunamathela, ubulukhuni obuphezulu futhi ugqoke ukumelana, ukunikeza uthango oluphezulu ngokumelene nomthelela ongemuhle wezemvelo, futhi futhi unalo okufanayo (noma okusondele) ngensimbi ukunwetshwa kokunwetshwa kwe-thermal.
2. Ukuhlanganiswa kwe-non-metallic
Indlela elula.
Ukwakha umsebenzi wepende kuyindlela enhle yokuvikela insimbi. Inzuzo yayo eyinhloko umnotho futhi kalula ukubuyiselwa kongqimba oluvikelayo. Kubalulekile futhi ukuthi kuhlale kugcinwe ithuba lokukhetha imibala ukunambitha. Kodwa-ke, indlela ayinaphutha. Imvamisa, upende nezimbobo ze-varnish zinokumelana nobuthakathaka kumswakama kanye nokushisa, kungasaphathwa umthelela wemishini.
3. Ukuhlanganiswa kwe-inorganic okungeyona eye-yensimbi
Ukuvikelwa okuthuthukile.
Enye yezindlela eziphumelela kakhulu zokuvikela lokho. Umnyombo wendlela uncishisiwe ukudala ifilimu evikelayo ngesakhiwo sensimbi. Kulokhu, insimbi ihlanganiswa nge-oxide noma ifilimu ye-phosphate. Okokuqala kusetshenziswa uma i-geometry yento edinga ukushiywa "ingafunwa". Le ndlela isetshenziswa, ngokwesibonelo, lapho ukuvikela izikhali namadivayisi anembile. Ifilimu lesibili lenziwa ukwehlisa umkhiqizo kwikhambi le-zinc noma i-manganese ngosawoti omuncu. Ngemuva kwalokho, umkhiqizo onjalo nawo ungapendiswa.
4. Ukuvikelwa kwe-Electrochemical
Izindlela zisetshenziswa.
Le ndlela yokuvikelwa ekuvezweni kokugqwala isetshenziswa kuphela uma insimbi ifakwa e-polarization. Lolu hlobo lokuvikelwa luyizinhlobo ezimbili - i-cathode ne-anode. Owokuqala usetshenziselwa ama-alloys anokuqukethwe kwensimbi. Indlela yokuvikela incishiswa ukuxhumanisa umkhiqizo kwi-cathode projector. Uhlobo lwesibili lokuvikelwa kokuhlanza futhi lutholakala ngokuxhuma umkhiqizo wokugqwala emthonjeni wamanje.
