Imikhiqizo

I-steel space frame idinga ukunakwa lapho uxubha i-topcoat.Indawo ehlanzekile idinga ukuxutshwa kabili, futhi ubukhulu buhlangabezana nezidingo.Lapho usebenza, kufanele ibhulashwe ngokuqhubekayo, ngaphandle kokugeleza noma ukuwa, ngombala ogqamile, ogcwele futhi olinganayo, futhi ngemva kokuqeda Ngemva komsebenzi, ukuhlolwa kwesibili kufanele kwenziwe ukuze kugwenywe ukushiywa.Inqubo yokudweba yefreyimu yesikhala sensimbi ihlukaniswe ngezinyathelo eziningana: ukuhlanza isisekelo sobuso, ukumbozwa kwe-primer, ukugqoka i-topcoat, ukuhlolwa nokwamukelwa.Umdwebo wepende wephrojekthi yesakhiwo sensimbi yesakhiwo kufanele wenziwe ngemuva kokuba isakhiwo sensimbi sifakwe futhi samukelwe.Ngaphambi kokudweba, kuyadingeka ukuhlanza ukugqwala, i-weld coating, i-welding spatter, amafutha, uthuli, njll engxenyeni yokugqoka.Uhlaka lwesakhiwo sesikhala sensimbi ukwakhiwa komdwebo wokulwa nokugqwala, ukumbozwa kwendawo ngopende okhethekile wokulwa nokugqwala.Njengamanje, izindlela eziyinhloko zokulwa nokugqwala kwezakhiwo zefreyimu, upende lwe-anti-corrosion lungahlukaniswa lube yi-primer ngokusho komsebenzi wokuvikela, upende ophakathi nopende ophezulu.Izici, ngayinye enesibopho sayo, ziye zahlanganiswa ukuze zenze uqweqwe oluyinhlanganisela ukuze kuthuthukiswe ukusebenza kwe-anti-corrosion kanye nokwandisa impilo yesevisi.I-epoxy zinc-rich-rich primer yenziwe ngenani elikhulu le-zinc powder kanye nenani elincane le-binder eyenza ifilimu.Izakhiwo ze-electrochemical ze-zinc ziphakeme kunezinsimbi, futhi lapho zigqwala, zinomphumela "wokuzidela", ukuze insimbi ivikelwe.Umkhiqizo we-corrosion zinc oxide ugcwalisa i-voids futhi wenze ukunamathela kuminyene kakhulu.Njengokuqala kochungechunge lwe-anti-corrosion coating, ukujiya ngokuvamile kungama-30 kuya ku-40 cm.Ukujiya kakhulu kulula ukuqhekeka nokuxebuka.
