Ngokuxhomekeke kwindlela yokusebenza, kukho iindlela ezintandathu eziphambili zokukhetha i-asidi kunye nokupasa kwensimbi engenasici: indlela yokucwiliswa, indlela yokunamathisela, indlela yokuxubha, indlela yokutshiza, indlela yokujikeleza kunye nendlela ye-electrochemical.Phakathi kwezi, indlela yokuntywiliselwa, indlela yokuncamathisela, kunye nendlela yokutshiza ifaneleke ngakumbi ukunyuswa kwe-asidi kunye nokupasa kweetanki zetsimbi kunye nezixhobo.
Indlela yokuntywiliselwa:Le ndlela yeyona ifanelekileyoimibhobho yentsimbi engenasici, iingqiniba, iinxalenye ezincinci, kwaye ibonelela ngeyona mpembelelo yonyango.Njengoko iindawo eziphathwayo zinokuntywiliselwa ngokupheleleyo kwisisombululo se-asidi kunye nesisombululo se-passivation, ukuphendulwa komphezulu kuphelile, kwaye ifilimu ye-passivation ixinene kwaye ifana.Le ndlela ifanelekile kwimisebenzi yebhetshi eqhubekayo kodwa ifuna ukuzaliswa ngokuqhubekayo kwesisombululo esitsha njengoko uxinaniso lwesisombululo esisabelayo kuncipha.I-drawback yayo kukuba inqunyelwe yimilo kunye nomthamo wetanki ye-asidi kwaye ayifanelekanga kwisixhobo somthamo omkhulu okanye imibhobho enemilo emide kakhulu okanye ebanzi.Ukuba ayisetyenziswanga ixesha elide, ukusebenza kungancipha ngenxa yokumka kwesisombululo, kufuna indawo ezinikeleyo, itanki yeasidi, kunye nezixhobo zokufudumeza.
Indlela yokuCoca: I-acid pickling paste yensimbi engenasici isetyenziswa kakhulu ekhaya kwaye ifumaneka kuluhlu lweemveliso.Amacandelo ayo aphambili abandakanya i-nitric acid, i-hydrofluoric acid, i-corrosion inhibitors, kunye ne-thickening agents, ngokwemilinganiselo ethile.Isetyenziswa ngesandla kwaye ifanelekile kulwakhiwo lwendawo.Isebenza kwi-pickling kunye ne-passivation ye-welds yensimbi engenasici, i-discoloration emva kwe-welding, i-deck top, iikona, ii-angles ezifileyo, i-ladder backs, kunye neendawo ezinkulu ngaphakathi kwamagumbi olwelo.
Iingenelo zendlela yokuncamathisela kukuba ayifuni izixhobo ezikhethekileyo okanye indawo, izixhobo zokufudumeza azidingeki, ukusebenza kwisayithi kuguquguqukayo, i-acid pickling kunye ne-passivation igqitywe kwinqanaba elinye, kwaye lizimeleyo.I-passivation paste inobomi obude beshelufu, kwaye isicelo ngasinye sisebenzisa i-passivation paste entsha yokusetyenziswa kwexesha elinye.I-reaction iyayeka emva komgangatho we-passivation, iyenza ukuba ingabi lula kakhulu kwi-corrosion.Ayikhawulelwanga ngexesha lokuhlanjululwa okulandelayo, kwaye i-passivation kwiindawo ezibuthathaka ezifana ne-welds inokuqiniswa.Ukungalungi kukuba indawo yokusebenza kumqhubi inokuba ihlwempuzekileyo, ukuqina kwabasebenzi kuphezulu, iindleko ziphezulu kakhulu, kwaye umphumo wonyango lwangaphakathi lodonga lwemibhobho yentsimbi ingaphantsi kancinane, ifuna indibaniselwano kunye nezinye iindlela.
Indlela yokutshiza:Ifanelekile kwiindawo eziqingqiweyo, iindawo ezivaliweyo, iimveliso ezingatshatanga, okanye izixhobo ezinezakhiwo ezilula zangaphakathi zokucoca i-asidi kunye nokugqithisa, njengenkqubo yokutshiza i-pickling kumgca wokuvelisa isinyithi.Iinzuzo zayo kukusebenza ngokukhawuleza okukhawulezileyo, ukusebenza okulula, impembelelo encinci eyingozi kubasebenzi, kwaye inkqubo yokudluliselwa inokutshiza umbhobho kwakhona ngeasidi.Inomlinganiselo ophezulu wokusetyenziswa kwesisombululo.
