Malingana ndi njira yogwiritsira ntchito, pali njira zisanu ndi imodzi zopangira asidi pickling ndi passivation ya chitsulo chosapanga dzimbiri: njira yomiza, njira ya phala, njira yopopera, kupopera mbewu mankhwalawa, njira yozungulira, ndi electrochemical njira.Zina mwa izi, njira yomiza, phala, ndi kupopera mbewu mankhwalawa ndizoyenera kwambiri ku pickling acid ndi passivation ya akasinja osapanga dzimbiri ndi zida.
Njira Yomiza:Njirayi ndiyoyenera kwambirimapaipi achitsulo chosapanga dzimbiri, elbows, tizigawo ting'onoting'ono, ndipo amapereka chithandizo chabwino kwambiri.Monga ankachitira mbali akhoza kumizidwa kwathunthu mu asidi pickling ndi passivation njira, padziko anachita wathunthu, ndi passivation filimu wandiweyani ndi yunifolomu.Njirayi ndiyoyenera kuchita ma batch mosalekeza koma imafuna kubwerezedwa mosalekeza kwa njira yatsopano pomwe kuchuluka kwa yankho kumachepa.Drawback yake ndi yocheperako ndi mawonekedwe ndi mphamvu ya thanki ya asidi ndipo siyoyenera zida zazikulu kapena mapaipi okhala ndi mawonekedwe aatali kapena otambalala.Ngati sichigwiritsidwa ntchito kwa nthawi yayitali, mphamvuyo imatha kuchepa chifukwa cha kusungunuka kwa madzi, kumafuna malo odzipereka, thanki ya asidi, ndi zida zotenthetsera.
Njira Yophatikizira: phala la asidi pickling zitsulo zosapanga dzimbiri amagwiritsidwa ntchito m'nyumba ndipo amapezeka mu mndandanda wa mankhwala.Zigawo zake zazikulu ndi nitric acid, hydrofluoric acid, corrosion inhibitors, ndi thickening agents, mosiyanasiyana.Amagwiritsidwa ntchito pamanja ndipo ndi oyenera kumanga pa malo.Imagwiritsidwa ntchito ku pickling ndi passivation ya zitsulo zosapanga dzimbiri zitsulo welds, kusinthika pambuyo kuwotcherera, nsonga za sitimayo, ngodya, ma ngodya zakufa, makwerero kumbuyo, ndi malo akuluakulu mkati mwa zipinda zamadzimadzi.
Ubwino wa njira ya phala ndikuti sichifunikira zida zapadera kapena malo, zida zotenthetsera sizifunikira, ntchito pamalopo ndi yosinthika, pickling ya asidi ndi passivation zimamalizidwa mu sitepe imodzi, ndipo ndizodziyimira pawokha.Phala la passivation limakhala ndi nthawi yayitali ya alumali, ndipo pulogalamu iliyonse imagwiritsa ntchito phala latsopano kuti ligwiritse ntchito kamodzi.Zimene amasiya pambuyo wosanjikiza pamwamba pa passivation, kupanga izo zochepa sachedwa kwambiri dzimbiri.Sizoletsedwa ndi nthawi yotsuka yotsatizana, ndipo passivation m'madera ofooka monga welds akhoza kulimbikitsidwa.The kuipa ndi kuti malo ntchito kwa woyendetsa kungakhale osauka, ntchito mwamphamvu ndi mkulu, ndalama ndi mkulu, ndi zotsatira za mkati khoma mankhwala a mapaipi zosapanga dzimbiri ndi otsika pang'ono, amafuna osakaniza ndi njira zina.
Njira yopopera mankhwala:Oyenera malo okhazikika, malo otsekedwa, mankhwala amodzi, kapena zida zokhala ndi zosavuta zamkati zopangira acidic pickling ndi passivation, monga kupopera mbewu mankhwalawa pamzere wopangira zitsulo.Ubwino wake ndikuthamanga mosalekeza, kugwira ntchito kosavuta, kuwononga pang'ono kwa ogwira ntchito, ndipo njira yosinthira imatha kupoperanso payipi ndi asidi.Ili ndi kuchuluka kwakukulu kogwiritsa ntchito yankho.
