Ingxube yethusiukugqwala
ukugqwala komkhathi
Ukugqwala komkhathi kwezinto zensimbi ikakhulukazi kuncike emhwamukeni wamanzi osemkhathini kanye nefilimu yamanzi ebusweni bento.Umswakama ohlobene womkhathi lapho izinga lokubola komkhathi wensimbi liqala ukwanda kakhulu libizwa ngokuthi umswakama obalulekile.Umswakama obalulekile wama-alloys ethusi nezinye izinsimbi eziningi uphakathi kuka-50% no-70%.Ukungcola okusemkhathini kunomthelela omkhulu ekugqwaleni kwama-alloys ethusi.
Ukubola kwezitshalo kanye negesi ephumayo ekhishwa izimboni kwenza igesi ye-ammonia ne-hydrogen sulfide ibe khona emkhathini.I-ammonia isheshisa kakhulu ukugqwala kwe-alloys yethusi neyethusi, ikakhulukazi ukugqwala kwengcindezi.Ukungcola okune-acidic okufana ne-C02, SO2, NO2 emkhathini wezimboni zasemadolobheni kuncibilika kufilimu yamanzi kanye ne-hydrolyzed, okwenza ifilimu lamanzi libe ne-asidi kanye nefilimu evikelayo ingazinzi.
ukugqwala kwendawo ye-splash
Ukuziphatha kokugqwala kwama-alloys ethusi endaweni yokuchaphaza kwamanzi olwandle kusondele kakhulu kulokho okusemoyeni wasolwandle.Noma iyiphi ingxubevange yethusi enokumelana okuhle nokugqwala emoyeni oqinile wasolwandle izophinde ibe nokugqwala okuhle kokugqwala endaweni ye-splash.Indawo ye-splash inikeza umoya-mpilo owanele ukusheshisa ukugqwala kwensimbi, kodwa yenza kube lula ngama-alloys ethusi nawethusi ukuthi ahlale engenzi lutho.Izinga lokugqwala lama-alloys ethusi elivezwe endaweni ye-spatter ngokuvamile alidluli ku-5 μm/a.
ukugqwala kwengcindezi
Ukuqhekeka kwe-quaternary yethusi kufanekisela ukugqwala kwengcindezi kwama-alloys ethusi.Ukuqhekeka kwesizini kwatholwa ekuqaleni kwekhulu lama-20 futhi kubhekisela emifantwini engxenyeni yebhokisi lenhlamvu lapho ishwabana ibheke ngasekhanda lempi.Lesi simo sivame ukwenzeka ezindaweni ezishisayo, ikakhulukazi ngenkathi yezimvula, ngakho-ke kubizwa ngokuthi ukuqhekeka kwesizini.Ngenxa yokuthi ihlobene nokuphuma kwe-ammonia noma i-ammonia, ibizwa nangokuthi i-ammonia cracking.Eqinisweni, ukuba khona kwe-oksijini nezinye izinto eziphilayo, kanye nokuba khona kwamanzi, nakho kuyizimo ezibalulekile zokugqwala kokucindezeleka kwethusi.Ezinye izindawo ezingabangela ukucindezeleka ukugqwala kokuqhekeka kwama-alloys ethusi zihlanganisa: umkhathi, amanzi ahlanzekile, namanzi olwandle angcoliswe kakhulu yi-SO2;i-sulfuric acid, i-nitric acid, isitimu, nezixazululo ezinamanzi njenge-tartaric acid, i-acetic acid, ne-citric acid, i-ammonia ne-mercury esetshenziselwa ukuhlanza izingxenye.
Ukubola kokubola
I-Dezincification yethusi iwuhlobo olujwayelekile lokugqwala kwe-alloy ye-copper de-composition, engenzeka ngesikhathi esisodwa nenqubo yokugqwala kwengcindezi, noma ingenzeka yodwa.Kunezinhlobo ezimbili ze-dezincification: eyodwa i-layer exfoliation uhlobo dezincification, esesimweni sokugqwala okufanayo futhi eyingozi kancane ekusetshenzisweni kwezinto;Amandla ezinto ezibonakalayo ancishiswa kakhulu, futhi ingozi inkulu.
Ukugqwala endaweni yasolwandle
Ngaphezu kwendawo esemkhathini wasolwandle, ukugqwala kwengxube yethusi endaweni yasolwandle kuhlanganisa nendawo yokuchaphaza kwamanzi olwandle, indawo yobubanzi begagasi kanye nendawo yokucwiliswa ngokuphelele.
