Qhov sib txawv ntawm tooj dag, liab tooj liab, Bronze thiab Cupronickel
May 20, 2022
1. Cov xim sib txawv.
Cov xim ntawm tooj dag yog daj, xim ntawm tooj liab yog ntshav-liab, xim ntawm bronze yog xiav, thiab xim ntawm dawb tooj liab yog nyiaj-dawb.
2. Cov tshuaj lom neeg muaj pes tsawg leeg sib txawv.
Brass yog ib qho alloy uas muaj tooj liab thiab zinc. Brass uas muaj tooj liab thiab zinc hu ua tooj dag zoo tib yam. Yog tias nws muaj ob lossis ntau lub ntsiab lus, cov ntsiab lus uas feem ntau ntxiv yog txhuas, tin, aluminium, thiab lwm yam. Ntau yam alloys hu ua tooj dag tshwj xeeb.
Liab tooj liab yog ib qho tooj liab ntshiab, uas feem ntau tuaj yeem suav tias yog tooj liab ntshiab, tab sis nws tsis tas yuav ntshiab tooj liab, thiab qee zaum me me ntawm deoxidizing cov ntsiab lus lossis lwm cov ntsiab lus ntxiv los txhim kho cov khoom siv thiab kev ua tau zoo, yog li nws kuj raug cais tawm. raws li tooj liab alloy.
Bronze yog ib qho hlau ntawm cov tooj liab dawb (liab tooj liab) ntxiv nrog cov tin lossis txhuas.
Cupronickel yog tooj liab-raws li alloy nrog npib tsib xee ua lub ntsiab additive. Cov tooj liab-nickel binary alloy yog hu ua cupronickel zoo tib yam; cupronickel alloy nrog manganese, hlau, zinc, txhuas thiab lwm yam yog hu ua complex cupronickel.
3. Kev siv sib txawv.
tooj dag muaj zog hnav tsis kam, thiab tooj dag feem ntau yog siv los tsim cov li qub, cov kav dej, txuas cov kav dej rau cov cua txias sab hauv thiab sab nraud, thiab cov tshuab hluav taws xob.
Cov hluav taws xob conductivity thiab thermal conductivity ntawm tooj liab liab yog qhov thib ob tsuas yog nyiaj, thiab tau siv dav hauv cov khoom siv hluav taws xob thiab thermal conductivity. Tooj liab muaj corrosion kuj zoo nyob rau hauv cov huab cua, dej hiav txwv thiab ib co non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkalis, ntsev tov thiab ntau yam organic acids (acetic acid, citric acid).
Bronze muaj cov yam ntxwv ntawm qhov qis melting point, siab hardness, muaj zog plasticity, hnav tsis kam, corrosion kuj, ci xim, thiab lwm yam. Nws yog tsim rau casting ntau yam khoom, mechanical qhov chaw, bearings, zog, thiab lwm yam.
Piv nrog rau lwm cov tooj liab alloys, cupronickel muaj qhov tshwj xeeb zoo txhua yam thiab lub cev muaj zog, zoo ductility, siab hardness, xim zoo nkauj, corrosion kuj, thiab sib sib zog nqus kos zog. Nws yog dav siv hauv nkoj tsim, petrochemical, khoom siv hluav taws xob, khoom siv, khoom siv kho mob, khoom siv niaj hnub, khoom siv tes ua thiab lwm yam kev lag luam, thiab tseem yog ib qho tseem ceeb tiv thaiv thiab thermocouple alloys.
