Nzira yekubvisa sei ngura kubva kune iron railing?

1. Kubvisa ngura nemaoko: Kushandisa maturusi emaoko akadai sepepa resimbi, scraper, spatula, uye wire brush.Iyi nzira ndeyekusimba kwevashandi, kushomeka kwekugadzira, asi kuri nyore uye kuchinjika kushanda, kuchiri kugamuchirwa.

2. Mechanical rust kubvisa: Kushandisa kukanganisa uye kukwesha kwesimba remagetsi kubvisa ngura.Michina inowanzoshandiswa inosanganisira bhurasho remhepo, pfuti yekubvisa ngura, bhurashi remagetsi, vhiri rejecha remagetsi, nezvimwewo. Zvikamu zviduku zvesimbi zvinogona kuiswa mumabhakiti akazadzwa nejecha rejecha kana huni huni uye kufamba nekumhanya kwe40-60 rpm.Kuburikidza nekudhumhana, kugadzirwa kwakanyanya uye kunaka kwemhando yekubvisa ngura, iyo yakashandiswa zvakanyanya.

3. Kubvisa ngura yejekiseni: Inofambiswa ne mechanical centrifugal force kana mhepo yakadzvanywa uye high pressure mvura, pfapfaidza abrasive (jecha kana simbi mabhora) panzvimbo yeworkpiece nekumhanya kukuru kuburikidza nemuromo wakakosha, uye bvisa tsvina (kusanganisira yakakuvara yekare pendi ganda. ) uye corrosion ine simba rayo uye kukweshana, ine kugadzirwa kwakanyanya uye kunaka kwekurapa.Iyo sandblasted simbi yepamusoro yakanyungudika zvishoma kuti iwedzere kusungirirwa kwesimba rekuputira uye pamusoro pesimbi.Asi kushata kwayo hakufanire kudarika 1/3 yehupfu hwehuputi.Nzira dzinowanzoshandiswa dzejecha dzokubvisa ngura dzinosanganisira kuputika kwejecha rakaoma, kuputika kwejecha rakanyorova, kuputika kwejecha kusina guruva uye kuputika kwejecha kwemvura yakasimba.

4. Kemikari kubvisa ngura: Uchishandisa acid solution uye iron oxides, nyungudutsa uye svuura pasi pevhu kuti uwane chinangwa chekubvisa ngura.Saka inozivikanwawo se "acid washing" uye kudzivirira ngura.Kune akawanda magadzirirwo emakemikari ekubvisa ngura, kazhinji sulfuric acid solution ye7% kusvika 15% (kana 5% yemunyu patafura) inoshandiswa senge acid yekubvisa ngura.Kuti udzivise sulfate corrosion yesimbi, shoma shoma ye corrosion inhibitors yakadai se rodine uye thiourea inogona kuwedzerwa.Mukuwedzera, inogonawo kushandisa phosphate acid, nitrate acid, hydrochloric acid uye zvichingodaro kuita zvakasiyana-siyana kugeza asidhi uye kubvisa ngura mhinduro.Kune nzira dzakawanda dzekunhonga, kazhinji kushandisa impregnated acid washing method, spray pickling method.Kunze kwezvo, asidhi cream, zvichienderana nemamiriro chaiwo.
