Ingxubevange yobheduukufunyanwa kokwakheka kunye neempawu?Ziziphi iindlela zokufumanisa ukubunjwa kwe-alloy copper?Amanyathelo okubona ukwakheka kwengxubevange yobhedu?Ziziphi iimpawu zokufumanisa ukubunjwa kwe-alloy yobhedu?Ukuqulunqwa kwe-alloy yobhedu esithetha ngayo apha ikakhulu kubhekisela kwizinto eziqulethwe kwi-alloy yobhedu, ngokuqinisekileyo, kuquka ukungcola.Kufuneka kubekho ubhedu ekubunjweni kwee-alloys zethusi, akukho mathandabuzo malunga nale nto.I-alloys zobhedu ziquka ubhedu, ubhedu kunye ne-cupronickel.Ubhedu obomvu aluyi-alloy yobhedu, kodwa ubhedu olucocekileyo.Kukho iindlela ezimbini eziphambili zokufumanisa ukubunjwa kwe-alloy copper.Iindlela ezahlukeneyo zokubona ukubunjwa kwe-alloy copper zineempawu ezahlukeneyo.Kukho izixhobo ezininzi zokubona ukubunjwa kwe-alloy copper.
Indlela yokubona ukwakheka kwengxubevange yobhedu?
1. Indlela yohlalutyo lweekhemikhali zeClassical: Iindlela ezisetyenziswa ngokuqhelekileyo kuhlalutyo lweekhemikhali zeklasi yindlela ye-titration kunye ne-gravimetric method.
(1) Indlela ye-Titration: Ngokutsho kweentlobo ezahlukeneyo zeekhemikhali, iindlela ze-titration zihlukaniswe zibe yi-acid-base titration, i-complexometric titration, i-redox titration kunye ne-precipitation titration.Ngokwendlela yenkqubo ye-titration kunye nokuphendula kweekhemikhali, iindlela ze-titration zahlulwe zibe yi-titration ngqo, i-titration engathanga ngqo, i-back titration, kunye ne-displacement titration.
(2) Indlela ye-Gravimetric: Iindlela ze-gravimetric ezisetyenziswa ngokuqhelekileyo kwii-alloys zethusi ziquka indlela yokuhlukana okunzulu, indlela yokwahlukana okuguquguqukayo, indlela yokuhlukanisa i-electrolytic kunye nezinye iindlela zokuhlukana.Ngokomzekelo, indlela ye-silicic acid dehydration gravimetric isetyenziswa ngokuqhelekileyo ukufumanisa i-silicon, indlela ye-electrolytic gravimetric yokubona ubhedu, kunye ne-beryllium pyrophosphate gravimetric indlela yokubona i-beryllium.
2. Indlela yokuhlalutya i-instrumental: Indlela yokuhlalutya i-instrumental inokwahlulwa ibe yindlela yohlalutyo lwe-optical, indlela yohlalutyo lwe-electrochemical, indlela yokuhlalutya i-chromatographic, njl.Phakathi kwabo, uhlalutyo lwe-electrochemical lunokwahlulwa lube yindlela yokuhlalutya okunokwenzeka, indlela yokuhlalutya i-conductometric, indlela yokuhlalutya i-electrolytic, indlela yokuhlalutya kweCoulomb, indlela yokuhlalutya i-polarographic, njl.
