Tooj alloynrhiav kom tau muaj pes tsawg leeg thiab cov yam ntxwv?Dab tsi yog txoj kev tshawb nrhiav ntawm tooj liab alloy muaj pes tsawg leeg?Cov kauj ruam nrhiav kom tau tooj liab alloy muaj pes tsawg leeg?Dab tsi yog cov yam ntxwv ntawm tooj liab alloy muaj pes tsawg leeg nrhiav kom pom?Cov tooj liab alloy muaj pes tsawg leeg peb tab tom tham txog ntawm no feem ntau yog hais txog cov ntsiab lus muaj nyob hauv cov tooj liab alloy, tau kawg, suav nrog impurities.Yuav tsum muaj tooj liab nyob rau hauv muaj pes tsawg leeg ntawm tooj liab alloys, tsis muaj kev tsis ntseeg txog qhov no.Copper alloys feem ntau suav nrog tooj dag, bronze thiab cupronickel.Liab tooj liab tsis yog tooj liab alloy, tab sis tooj liab ntshiab.Muaj ob txoj hauv kev tseem ceeb rau kev tshawb pom ntawm tooj liab alloy muaj pes tsawg leeg.Txawv tooj liab alloy muaj pes tsawg leeg nrhiav kom tau txoj kev muaj cov yam ntxwv sib txawv.Muaj ntau ntau yam cuab yeej rau kev tshawb pom ntawm tooj liab alloy muaj pes tsawg leeg.
Copper alloy muaj pes tsawg leeg nrhiav kom tau txoj kev?
1. Classical chemical analysis method: Cov txheej txheem siv ntau tshaj plaws hauv kev tshuaj ntsuam tshuaj classical yog txoj kev titration thiab txoj kev gravimetric.
(1) Titration method: Raws li ntau hom tshuaj tiv thaiv, titration txoj kev muab faib ua acid-base titration, complexometric titration, redox titration thiab nag lossis daus titration.Raws li cov txheej txheem titration thiab tshuaj lom neeg cov tshuaj tiv thaiv, titration txoj kev tau muab faib ua titration ncaj qha, indirect titration, rov qab titration, thiab hloov chaw titration.
(2) Gravimetric method: Cov kev siv gravimetric feem ntau siv rau tooj liab alloys xws li txoj kev sib sib zog nqus sib sib zog nqus, txoj kev sib cais tsis sib haum, txoj kev sib cais electrolytic thiab lwm txoj kev sib cais.Piv txwv li, silicic acid dehydration gravimetric txoj kev yog feem ntau siv los ntes silicon, electrolytic gravimetric txoj kev los ntes tooj liab, thiab beryllium pyrophosphate gravimetric txoj kev los kuaj beryllium.
2. Instrumental analysis method: Instrumental analysis method yuav muab faib ua optical analysis method, electrochemical analysis method, chromatographic analysis method, etc. Ntawm lawv, copper alloy mas adopts optical analysis method thiab electrochemical analysis method.Ntawm lawv, electrochemical tsom xam yuav muab faib ua tej yam kev soj ntsuam txoj kev, conductometric tsom xam txoj kev, electrolytic tsom xam txoj kev, Coulomb tsom xam txoj kev, polarographic tsom xam txoj kev, thiab lwm yam raws li qhov sib txawv hluav taws xob teeb liab ntsuas.
