Ukucoca iindleko zexesha elidala kubandakanya ukususa ukungcola, uthuli, kunye nokucwangciswa kwe-oxidized from surface of the currency. Ngoko iziseko zokuhlambulula iimali kufuneka zikwazi ukuphela kwezibalo kuphela, kodwa kunye neendwendwe eziqhelekileyo.
Ngaphambi kokuba uqale ukuhlambulula imali, kufuneka ufumane ukubunjwa kwaloo mali. Kwaye, ngokuxhomekeka kwindlela yokwakhiwa, kufuneka ukhethe iindlela zokuhlambulula imali.
Ukucocwa kweemveliso zeemaliUkucocwa kwamatshini kufanelekileyo kwiimali zemali ezenziwe kwiphina impahla. Ukwenza oku, udinga ibhulashi elithambileyo, okanye i-toothbrush. Lungisa i-salidi kwisisombululo sesobho, uze uwabhinqe. Emva koko, hlamba phantsi kwamanzi ahlanzekileyo, kwaye usule ngokucophelela. Musa ukufihla imali yesitoreji ukuze uqinisekise ukuba abanalo linye lokunyuka kwamanzi.
Nangona kunjalo, kufuneka kukhunjulwe ukuba ngoncedo lokuhlanjululwa okunjalo, unokukrazula kuphela umkhondo wothuli kunye nentlaka. Imizila ye-oxidation okanye ukubola ayinakususwa ngale ndlela. Kodwa ekucoceni iibhedi, i-pastes okanye i-powders abavumelekanga ukuba bafake isicelo, njengoko beshiya imirhubhe ebusweni.
Ukucocwa kweemali zegolide
Iingqekembe zegolide zigcinwe kwaye azidingeki ukuba zihlambuluke. Baya kuhlanjwa nje ngamanzi asepha. Esikhundleni sebhashi, thabatha ingcezu yengubo ephothiweyo, kwaye uyichoboze ngokukhawuleza ngemali. Ukusetyenziswa kwebhayisiki akuvumelekanga. Nangona ibhontshi kunye nenqwaba elula kakhulu kunokushiya imirhubhe emininzi kwigolide, kodwa ayibonakali ngokukhawuleza. Kuyafana nakweyimbobo enokugqithisa, inokuyonakalisa nomphezulu wengqekembe.
Ngamanye amaxesha kwiimali zegolide kukho amachashaza amnyama. Akunjalo ukungcola, kodwa iintlobo zeengqungquthela ezithintela i-alloy ngaphambi kokuba ihlawulwe. Kwaye, ngelishwa, akukho ndlela yokucoca iimali ezinokuyicoca.
Ukucocwa kweemali zesilivere
Indlela yokucoca iimali zesilivere zixhomekeke kwisampuli yesilivere apho zenziwe khona.
Iimali zemali ezi-625 nangaphezulu, ukucoca kunye ne-ammonia kufanelekile.
Ngesilivere esisezantsi, ungasetyenziswa ukucoceka kweemali ze-citric acid (okanye ijusi yemvelo).
Xa uthela iibhedi kwisisombululo se-ammonia okanye i-citric acid, kufuneka uguquke ngokukhawuleza, okanye ucoce ucoce ngebhashi. Bamba iintengo zemali kwisisombululo kude kube yilapho ukungcola kuphele ngokupheleleyo. Emva koko susela ngamanzi acocekileyo kwaye ume.
Ukuba ukungcola komelele, ke ungasebenzisa ukucoca kweengqekembe nge-baking soda. Ukwenza oku, kongeza amanzi ambalwa kwi-soda kunye ne-slurry eyenziwe ngokuxubha umphezulu wengqekembe.
Ukucoca iCopper yeCons
Iingxowa-mali zethusi zihlala zicocwa ngesisombululo sesepha. Ngenxa yoko, iinkozo zibhaptizwa kwisisombululo sesepha kwaye zikhutshwe ngezikhathi kwaye zicocwe ngebhasi. Kwaye kwada kwaphela ukutshabalalisa ukungcola. Kufuneka kuqatshelwe ukuba le nkqubo inokude kwaye ichitha ixesha. Iimali kufuneka zigcinwe ngamanzi esephaphu ukuya kwiiveki ezi-2, kwaye ukuxubha kwenziwa rhoqo kwiintsuku ezine. Emva kokuba ususe iinkozo, kufuneka ubilise kwioli kwaye uzihlambe ngendwangu yesaka. Oku kuya kunika ukukhanya okukhethekileyo, kwaye kudala isiseko sokukhusela kwimali.
Iingxowa zethusi, iviniga isetyenziswa kwakhona. Oku kulungele iwayini eliqhelekileyo le-viniga 5-10%. Ubungakanani bokucwiliswa kwengqekembe kwisisombululo se-acetic kuxhomekeke kwisilinganisi se-oxidation, kwaye siyahluka kwiimitha ezimbalwa ukuya kwiiyure eziliqela.
Ukucoca iimali zenziwe nge-zinc-iron alloy
Ukuqala, ngoncedo lwenaliti, iimpawu zokugqwala kunye neplate ecocekileyo zisuswe ebusweni beemali. Emva koko uhlamvu lwemali luhla kwisisombululo esinobuthakathaka kakhulu se-hydrochloric acid. Kuyimfuneko ukugcina isondlo rhoqo phezu kwemali. Ngexesha apho i-oxides ne-rust fuse, kuya kubakho ukususa imali leyo kwisisombululo, kwaye uhlanza ngaphantsi kwamanzi. Emva koko i-coin isomile kwaye ihlahliwe ukuze ibonakale.
