Copper Industry Knowledge: Liab Copper
Cov ntsiab lus ntawm tooj liab liab: Cov xim liab-liab nrog tooj liab yog cov khoom tseem ceeb thiab ib qho me me ntawm phosphorus ntxiv rau deoxidized ingot thaum melting thiab casting. Liab tooj liab kuj hu ua "pure tooj liab", "ntshiab tooj liab" los yog "liab tooj liab". "Liab tooj liab" yog ib lub npe nrov ntawm cov neeg, thiab "liab tooj liab" yog lub npe ntawm kev lag luam.
Kev faib tawm tooj liab liab: tooj liab liab tuaj yeem muab faib ua plaub pawg raws li nws muaj pes tsawg leeg: tooj liab zoo tib yam (T1, T2, T3), tooj liab tsis muaj oxygen, phosphorus-deoxidized tooj liab, thiab tooj liab tshwj xeeb nrog me me ntawm cov ntsiab lus alloying (arsenic. tooj liab, tellurium tooj liab, nyiaj tooj liab, thiab lwm yam).
Cov yam ntxwv ntawm liab tooj liab: siab purity, zoo qauv, thiab tsis tshua muaj oxygen cov ntsiab lus. Tsis muaj pores, xuab zeb ob lub qhov muag, looseness, zoo heev hluav taws xob conductivity, siab precision ntawm pwm nto tsim los ntawm electro-erosion, tom qab tshav kub txheej txheem, lub electrode tsis muaj directionality, haum rau precision ua, thiab muaj zoo thermal conductivity, processability, ductility, corrosion kuj, thiab lwm yam. Ntshiab tooj liab me me li ib tee dej yuav raug rub mus rau hauv ib lub filament mus txog ob kilometers ntev, los yog dov mus rau hauv ib tug yuav luag pob tshab ntawv loj dua ib lub txaj. Cov cuab yeej tseem ceeb tshaj plaws ntawm cov tooj liab liab yog nws cov khoom siv hluav taws xob zoo heev, uas yog qhov thib ob tsuas yog nyiaj ntawm tag nrho cov hlau. Tab sis tooj liab yog pheej yig dua li nyiaj, yog li nws tau dhau los ua "protagonist" ntawm kev lag luam hluav taws xob. Cia peb saib cov yam ntxwv ntawm cov qib sib txawv ntawm cov tooj liab liab, raws li hauv qab no
1. C1100: Nws muaj thermal conductivity, processability, ductility, corrosion kuj thiab huab cua tsis kam.
2. C1210: Nws muaj cov txheej txheem zoo, ductility, weldability, corrosion kuj, huab cua tsis kam thiab hluav taws xob thermal conductivity.
3. C1220: Nws muaj cov txheej txheem zoo, ductility, weldability, corrosion kuj, huab cua tsis kam thiab hluav taws xob thermal conductivity, thiab yuav tsis tsim hydrogen embrittlement ntawm qhov kub thiab txias.
4. C1221: Nws muaj cov txheej txheem zoo, ductility, weldability, corrosion kuj, huab cua tsis kam thiab hluav taws xob thermal conductivity, thiab yuav tsis tsim hydrogen embrittlement ntawm qhov kub thiab txias.
