Ukuhlanza izinhlamvu zemali

Ukuhlanza izinhlamvu zemali ezindala kuhilela ukukhipha ukungcola, uthuli, kanye noqweqwe oluxubile kusuka ebusweni behlamvu lwemali. Ngakho-ke izinto eziyisisekelo zokuqoqa zemali zidinga ukwazi i-numismatists kuphela, kodwa futhi i-hostess evamile.

Ngaphambi kokuba uqale ukuhlanza uhlamvu lwemali, udinga ukucacisa ukwakheka okwenziwe ngale ngqikithi. Futhi, kuye ngokubunjwa, udinga ukukhetha izindlela zokuhlanza izinhlamvu zemali.

Ukuhlanza imishini kufaneleka ngemali esetshenziswe kunoma iyiphi impahla. Ukuze wenze lokhu, udinga ibhulashi elithambile, noma ibhuloho lamazinyo. Lungiselela izinhlamvu zemali kwisisombululo se-soapy, bese uwashayela. Ngemuva kwalokho, ugeze ngaphansi kwamanzi ahlanzekile, bese usula ngokucophelela. Musa ukufihla imali yesitoreji kuze kube yilapho uqinisekisa ukuthi awunayo ihlumela elilodwa lokuswakama.

Kodwa-ke, kufanele kukhunjulwe ukuthi ngosizo lokuhlanza okunjalo, ungakwazi ukuqeda imidwebo yothuli nokungcola kuphela. Imikhakha ye-oxidation noma ukubhujiswa ayikwazi ukususwa ngale ndlela. Kodwa ngokuhlanza izinhlamvu zemali, ama-pastes noma ama-powders awavunyelwe ukusebenzisa, njengoba ephuma emanxebeni phezulu.

Ukuhlanza izinhlamvu zegolide

Izimali zegolide zigcinwe kahle futhi akudingeki zihlanzwe. Bangakwazi nje ukugezwa ngamanzi asozini. Esikhundleni sebhayisikili, thatha ucezu lendwangu elithambile, bese uluhluza kancane ngemali. Ukusetshenziswa kwebhashishi akuvumelekile. Ngisho nokushayela okunezinqwaba ezilula kakhulu kungashiya imivimbo emincane ngegolide, kodwa ayiveli ngokushesha. Okufanayo kusebenza ngendwangu enzima, kungaphazamisa ubuso bezimali.

Ngezinye izikhathi kwizinhlamvu zegolide kukhona amachashazi amnyama. Akusilo ukungcola, kodwa izinhlayiya ezingaphandle ezithinta i-alloy ngaphambi kokuba imali ishicilelwe. Futhi, ngeshwa, akukho ndlela yokuhlanza zemali ingabasusa.

Ukuhlanza izinhlamvu zesiliva

Indlela yokuhlanza zemali zesiliva incike kwisampula esiliva esenziwa kuyo.

Ngemali yesamba yezingu-625 nangaphezulu, ukuhlanza nge-ammonia kufanelekile.

Ukuze uthole isiliva ephansi, ungasebenzisa ukuhlanzwa kwemali nge-citric acid (noma ijusi yemvelo yemvelo).

Uma uchithela izinhlamvu zemali zibe yisisombululo se-ammonia noma i-citric acid, kufanele uguquke ngezikhathi ezithile, noma ngisho uhlanze ukungcola ngebhashi. Bamba izinhlamvu zemali kusixazululo kuze kuphele ukungcola ngokuphelele. Bese ugeza ngamanzi ahlanzekile bese usomile.

Uma ukungcola akunamandla, khona-ke ungasebenzisa ukuhlanzwa kwezimali zemali nge-baking soda. Ukwenza lokhu, engeza amanzi amancane kwi-soda kanye ne-slurry eyakhiwe ngokubhoboza ubuso behlamvu lwemali.

Ukuhlanza Izinhlamvu zemali ze Copper

Izinhlamvu zemithi zethusi ngokuvamile zihlanzwa ngesisombululo seseva. Ngenxa yalokhu, izinhlamvu zemali zibhapathizwa kwisisombululo sensiphu futhi zisuswa ngezikhathi futhi zihlanzwa ngebhashi. Futhi kuze kube yilapho ukunyamalala kokungcola. Kumele kuqashelwe ukuthi lokhu kuyinkqubo ende kakhulu isikhathi esiningi. Izinhlamvu zemali kufanele zigcinwe emanzini asozini kuze kube amasonto amabili, futhi ukuxubha kwenziwe njalo ezinsukwini ezine. Ngemuva kokususa izinhlamvu zemali, udinga ukubilisa emafutheni bese uzihlanza ngendwangu yesaka. Lokhu kuzonikeza ukukhanya okhethekile, futhi udale ungqimba oluvikelayo lwemali.

Ngemali yesimbi, uviniga nawo uyasetshenziswa. Lokhu kufanelekile kumviniga ovamile we-tablegar 5-10%. Isikhathi sokucwiliswa kwengqikithi kwisisombululo se-acetic sincike ngesilinganiso se-oxidation, futhi siyahlukahluka emaminithini ambalwa kuya emahoreni amaningana.

Ukuhlanza izinhlamvu zemali ezenziwe nge-zinc-iron alloy

Okokuqala, ngosizo lensiza, izimpawu zokugqwala kanye ne-plaque ezimhlophe zisuswe ebusweni behlamvu lwemali. Khona-ke uhlamvu lwemali luya esixazululweni esibuthakathaka kakhulu se-hydrochloric acid. Kubalulekile ukugcina ukuqondiswa njalo phezu kwemali. Ngesikhathi lapho i-oxides ne-rust ifinyelela khona, kuzodingeka ukuthi ususe imali esesisombululo, bese ugeza ngaphansi kwamanzi. Khona-ke leyo mali isomile futhi igubha ukuze ibonakale.
