1. Ukususwa kokugqwala okwenziwa ngesandla: Ukusebenzisa amathuluzi okwenziwa ngesandla njengephepha lensimbi, ukukhuhla, i-spatula, nebhulashi locingo.Le ndlela iwukuqina okukhulu kwabasebenzi, ukusebenza kahle kokukhiqiza okuphansi, kodwa ukusebenza okulula nokuvumelana nezimo, kusasetshenziswa.
2. Ukususwa kokugqwala ngomshini: Ukusebenzisa umthelela nokungqubuzana kwamandla emishini ukususa ukugqwala.Imishini esetshenziswa kakhulu ihlanganisa ibhulashi lomoya, isibhamu sokukhipha ukugqwala, ibhulashi likagesi, isondo lesihlabathi sikagesi, njll. Izingxenye zensimbi ezincane zingalayishwa emabhakedeni agcwele isihlabathi esiphuzi noma ama-chips ezinkuni futhi zihambe ngesivinini esingu-40-60 rpm.Ngokungqubuzana kokushayisana, ukusebenza kahle kokukhiqiza okuphezulu kanye nekhwalithi enhle yokukhipha ukugqwala, okusetshenziswe kabanzi.
3. Ukususwa kokugqwala komjovo: Kunikwe amandla ngomshini we-centrifugal force noma umoya ocindezelwe kanye namanzi anengcindezi ephezulu, fafaza i-abrasive (isihlabathi noma amabhola ensimbi) endaweni yokusebenza ngesivinini esikhulu ngombhobho okhethekile, futhi isuse ukungcola (kuhlanganise nesikhumba sikapende esidala esilimele. ) kanye nokugqwala okunamandla okuthinta kanye nokungqubuzana, nokusebenza kahle kokukhiqiza okuphezulu kanye nekhwalithi enhle yokwelapha.Indawo yensimbi ene-sandblasted ifakwe ama-serrated kancane ukuze kwandiswe amandla okubopha okunamathelayo nendawo yensimbi.Kodwa ubulukhuni bayo akumele budlule i-1/3 yobukhulu bokunamathela.Izindlela ezijwayelekile ezisetshenziswayo zokususa ukugqwala kwesihlabathi zifaka ukuqhunyiswa kwesihlabathi esomile, ukuqhunyiswa kwesihlabathi esimanzi, ukuqhunyiswa kwesihlabathi okungenathuli kanye nokuqhunyiswa kwesihlabathi esinomfutho ophezulu.
4. Ukususwa kokugqwala kwamakhemikhali: Ukusebenzisa ingxube ye-asidi nama-iron oxides, ncibilikisa futhi ucwecwe ungqimba lokugqwala okungaphezulu ukuze ufeze inhloso yokukhipha ukugqwala.Ngakho-ke kwaziwa nangokuthi "ukugeza i-asidi" nokuvimbela ukugqwala.Kunezinhlobo eziningi zokwenziwa kokususwa kokugqwala kwamakhemikhali, ngokuvamile isisombululo se-sulfuric acid sika-7% kuya ku-15% (noma u-5% wetafula likasawoti) sisetshenziswa njengesixazululo sokususa ukugqwala kwe-asidi.Ukuze uvimbele ukugqwala kwe-sulfate yensimbi, inani elincane le-corrosion inhibitor njenge-rodine ne-thiourea lingengezwa.Ngaphezu kwalokho, ingasebenzisa futhi i-phosphate acid, i-nitrate acid, i-hydrochloric acid nokunye ukwenza isixazululo esihlukene sokugeza i-asidi nokugqwala.Ziningi izindlela pickling, ngokuvamile usebenzisa impregnated acid washing indlela, fafaza pickling indlela.Ngaphandle kwalokho, ukhilimu we-asidi, kuye ngezimo ezithile.
