Dab tsi yog tooj dag, liab tooj liab, ntshav tooj liab, qhov txawv yog qhov twg
Jun 27, 2022
Qhov sib txawv ntawm tooj dag, tooj liab thiab liab tooj liab yog nyob rau hauv cov khoom sib txawv thiab siv:
Brass yog ib qho alloy uas muaj tooj liab thiab zinc. tooj dag ua los ntawm tooj liab thiab zinc yog hu ua tooj dag. Brass feem ntau yog siv rau hauv kev tsim cov li qub, cov kav dej, cov tshuab cua txias, cov kav dej sib txuas sab hauv thiab sab nraud thiab cov tshuab hluav taws xob.
2, liab tooj liab yog tooj liab ntshiab, tseem hu ua liab tooj liab, tooj liab yog yooj yim, vim nws cov xim yog xim liab thiab muaj npe. Saib tooj liab rau ntau yam khoom. Tooj liab yog muaj tooj liab ntshiab, nws melting point yog 1083 degree, tsis muaj isomerism transformation, tus txheeb ze ntom ntawm 8.9, tsib zaug ntawm magnesium. Qhov loj ntawm tib lub ntim yog kwv yees li 15 feem pua hnyav dua li cov hlau zoo tib yam.
3, tooj liab, tseem hu ua liab tooj liab yog tooj liab elemental, vim nws cov xim yog purplish liab thiab muaj npe. Saib tooj liab rau ntau yam khoom. Tooj liab yog muaj tooj liab ntshiab, nws melting point yog 1083 degree, tsis muaj isomerism transformation, tus txheeb ze ntom ntawm 8.9, tsib zaug ntawm magnesium.
Qhov txawv yog nyob rau hauv kev siv.
