Qhov sib txawv ntawm cov pas nrig tooj liab thiab tooj dag, nrog rau cov yam ntxwv, kev siv, muaj pes tsawg leeg, lub zog, thiab lwm yam.
Copper pas nrig yog ib hom uas tsis yog-ferrous hlau ua pas nrig uas muaj hluav taws xob conductivity.
Muaj ntau hom tooj liab pas nrig, xws li liab tooj liab rods, tooj dag rods, tin bronze rods thiab dawb tooj liab rods. Ntau hom tooj liab rods muaj cov txheej txheem molding sib txawv thiab cov yam ntxwv sib txawv. Copper pas nrig ua cov txheej txheem suav nrog extrusion, dov, nruam casting, kos duab, thiab lwm yam.
Lawv tau muab faib ua ob peb pawg: tooj liab, tooj liab rods, bronze rods, dawb tooj liab rods, thiab lwm yam. Qhov tseem ceeb tshaj plaws yog tooj liab rods thiab tooj liab rods; yuav muaj kev tsis meej pem hauv peb qhov kev yuav khoom txhua hnub. Yog li dab tsi yog qhov txawv ntawm cov pas nrig tooj liab thiab tooj dag?
Cov khoom sib txawv muaj cov yam ntxwv sib txawv thiab kev siv, thiab cov nqi kuj txawv. Copper rods yog kim tshaj li tooj dag rods.
Qhov sib txawv ntawm kev siv
tooj dag
Cov pas nrig tooj dag yog ib yam khoom zoo li tus pas nrig ua los ntawm cov hlau alloy ntawm tooj liab thiab zinc. Nws muaj npe tom qab nws cov xim daj. Nws melting point yog 934 ~ 967 degrees. Cov ntsiab lus zinc sib txawv kuj tseem yuav muaj xim sib txawv. Piv txwv li, yog cov ntsiab lus zinc yog 18% -20%, nws yuav yog xim liab-daj, thaum yog cov ntsiab lus zinc yog 20% -30%, nws yuav yog xim av-daj. Tsis tas li ntawd, tooj dag muaj lub suab tshwj xeeb thaum ntaus, yog li cov cuab yeej Eastern xws li gongs, cymbals, tswb, thiab horns, nrog rau cov twj paj nruag Western yog txhua yam ua los ntawm tooj dag.
Brass muaj cov khoom siv zoo thiab hnav tsis kam, thiab tuaj yeem siv los tsim cov cuab yeej precision, nkoj qhov chaw, phom plhaub, nws pib qhov chaw, khoom siv kho mob, khoom siv hluav taws xob thiab ntau yam khoom txhawb nqa, tsheb synchronizer rings, thiab lwm yam.
Tooj liab
Copper rods muaj npe tom qab lawv cov xim liab-liab. Lawv muaj cov khoom siv hluav taws xob zoo, thermal conductivity, corrosion kuj thiab kev ua haujlwm, thiab tuaj yeem welded thiab brazed. Nws tsis yog tooj liab dawb huv. Qee lub sij hawm me me ntawm deoxidizing cov ntsiab lus lossis lwm cov ntsiab lus tau ntxiv los txhim kho cov khoom siv thiab kev ua haujlwm, yog li nws kuj tau muab faib ua tooj liab alloy.
Cov txheej txheem txheej txheem tuaj yeem muab faib ua:
Ordinary tooj liab (T1, T2, T3, T4)
Oxygen-dawb tooj liab (TU1, TU2 thiab high-purity, nqus pa tsis muaj tooj liab)
Deoxidized tooj liab (TUP, TUMn)
Cov tooj liab tshwj xeeb (ntxiv me me ntawm cov ntsiab lus alloying, xws li arsenic tooj liab, tellurium tooj liab, nyiaj tooj liab)
Cov hluav taws xob conductivity thiab thermal conductivity ntawm tooj liab liab yog qhov thib ob tsuas yog nyiaj, thiab nws muaj hluav taws xob zoo, thermal conductivity thiab plasticity; nws yog ib qho yooj yim rau txheej txheem los ntawm kub nias thiab txias nias, thiab yog siv nyob rau hauv kev lag luam hluav taws xob. Ntau cov khoom siv hauv kev tsim cov xov hlau thiab cov hlua, txhuam, tshwj xeeb electro-corroded tooj liab rau hluav taws xob sparks thiab lwm yam khoom uas yuav tsum tau muaj zog conductivity.
Tooj liab muaj corrosion kuj zoo nyob rau hauv cov huab cua, seawater thiab tej yam uas tsis yog-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, ntsev tov thiab ntau yam organic acids (acetic acid, citric acid) thiab yog siv nyob rau hauv kev lag luam tshuaj.
Feature txawv
Qhov ceev yog txawv: qhov ceev ntawm liab tooj liab pas nrig yog 8.9-8.95 (electrolytic tooj liab), uas yog me ntsis siab dua; qhov ntom ntawm tooj dag pas nrig yog 8.52-8.62 (dov tooj dag), uas yog me dua.
Cov khoom sib txawv: cov khoom tseem ceeb ntawm cov pas nrig liab yog tooj liab, thiab cov ntsiab lus tooj liab tuaj yeem siab txog 99.95%; cov khoom ntawm tooj dag pas nrig suav nrog tooj liab thiab zinc, nrog cov ntsiab lus tooj liab ntawm 56% mus rau 68%; tshwj xeeb tooj dag kuj tseem muaj lwm yam impurities, yog li lawv tuaj yeem yooj yim sib txawv ntawm cov khoom xyaw ntshiab.
Qhov sib txawv ntawm lub zog: tooj dag pas nrig muaj ntau cov khoom xyaw, yog li nws lub zog siab dua, tab sis cov khoom tseem ceeb ntawm cov pas nrig tooj liab yog tooj liab, nrog rau qhov pib tsis muaj lwm yam impurities, yog li lub zog ntawm tooj liab liab kuj qis dua li ntawm tooj dag.
Copper pas nrig txoj kev
Txawm hais tias muaj ntau qhov sib txawv ntawm lawv, cov txheej txheem ntau lawm yog tib yam; cov txheej txheem tooj liab txoj kev muaj xws li extrusion, dov, nruam casting, kos duab, thiab lwm yam.
1. Extrusion-(rolling)-drawing-(annealing)-cov khoom tiav-cov khoom tiav.
2. Nruam casting (nce toj casting, kab rov tav los yog log hom, crawler hom, dipping) - (rolling) - kos duab - (annealing) - xov - khoom tiav.
3. Nruam extrusion-stretching-(annealing)-cov khoom tiav-cov khoom tiav.
