Izindaba

Izinto eziqondile zisetshenziselwa izinqubo ezithile. Isibonelo, izinto ezimelana nezigxivizo zeminwe ezinothayela azikwazi ukusetshenziswa kunqubo ye-electrophoretic, okuzokwenza ukuthi izingxenye ze-electrophoretic zikhishwe. Indlela yokubona ngokushesha ukuthi kukhona yini i-coating esobala ebusweni bezinto ezenziwe ngama-galvanized kuyikhono elibaluleke kakhulu.
I-passivation, ukumelana nezigxivizo zeminwe kanye nezinye izindlela zangemuva kokwelashwa ukusebenzisa ifilimu yangemuva kokwelashwa engenambala futhi esobala ku-substrate efakwe uthayela, okunzima ukuyibona ngokubonakalayo. Ziningi izindlela zokuhlonza ezingochwepheshe, kodwa ukuthola indlela engabizi kakhulu nephumelelayo kuwumgomo wethu.
Izindlela zokuhlola zokuhlolwa kwamakhemikhali
1. Ukuhlaziya izimiso
Ingqikithi yemikhiqizo yeminwe noma ye-passivation resistant ukufaka i-organic coating ku-substrate eyisithako. Ngenxa yokuba khona kwe-coating, singathola i-reagent yamakhemikhali ephendula nge-zinc layer esikhundleni se-coating, futhi ihlukanise ngokusho komehluko wejubane lokuphendula.
2. I-prop yokuhlola - isisombululo se-copper sulfate esingu-5%.
Okulandelayo, sethula kahle i-protagonist yalolu daba: isisombululo se-copper sulfate. Yiqiniso, uma ukugxila kungaphakeme kakhulu, ukugxila kwe-5% kwanele (anemibala futhi esobala).
3. Ukutholwa nokwahlulela
Isixazululo se-copper sulfate sizosabela ngesendlalelo se-zinc (Zn + CuSO4 = ZnSO4 + Cu), kanje:
Yehlisa isixazululo se-copper sulfate esingu-5% emkhiqizweni ongazweli izigxivizo zeminwe noma umenzi, futhi uwuyeke ume imizuzu emi-3, futhi isisombululo sisabonakala.
Beka eshidini likathayela elingagcotshiwe bese uliyeka lime imizuzu emi-3. Isixazululo sisabela ngesendlalelo se-zinc bese siphenduka sibe mnyama.
izindaba ezidinga ukunakwa
Ngesikhathi sokusebenza kwangempela, indawo yepuleti kufanele isulwe ngotshwala, ngaphandle kwalokho uwoyela we-antirust osalayo uzobambezela isivinini sokuphendula.
Ibhodlela lesixazululo, lahla phansi, imizuzu emi-5, xazulula zonke izinkinga!
Izixazululo ze-Fauvist
Okungenhla kuyisixazululo esilula kunazo zonke sezemfundo. Okulandelayo yizimpahla ezomile zangempela. Abafundi abangakaqedi ukufunda abakwazi ukujabulela le nzuzo!
Eqinisweni, uChaige ngokwakhe wasebenzisa indlela elula futhi esheshayo: indlela yokuhlikihla iminwe
Ngemuva kokuthi isampula lepuleti lisuliwe, sebenzisa iminwe yakho ukuze uhlikihle ngamandla futhi ngokuphindaphindiwe endaweni yepuleti (ukungqubuzana, okufana nejubane likadeveli ~ ~).
Iminwe eyenziwe yaba mnyama (impushana ye-zinc ewayo) ngamashidi angafakwa uthayela. Uma kungekho ukuguqulwa okusobala ebusweni, kubonisa ukuthi kukhona ukugqoka ngemuva kokwelashwa.
amazwi
Le ndlela idinga isipiliyoni esincane, kodwa ishibhile futhi iguquguquka kakhulu. Idingani indawo yokukhiqiza? Fast, elula, embi!!!
