Qhov sib txawv ntawm Phosphorus Deoxidized Copper thiab Ordinary Pure Copper
Cov tooj liab ntshiab yog dav paub tias yog cov khoom siv yooj yim uas muaj hluav taws xob zoo thiab thermal conductivity, tab sis nws tuaj yeem muab faib ua ntau hom raws li cov txheej txheem ntau lawm thiab kev tswj tsis huv, cov phosphorus deoxidized tooj liab thiab tooj liab ntshiab yog ob feem ntau siv. Txawm hais tias ob qho tib si muaj nyob rau hauv qeb ntawm cov khoom siv tooj liab nrog cov ntsiab lus tooj liab siab dua 99.9%, muaj qhov sib txawv ntawm cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv lub cev, cov txheej txheem tsim khoom, thiab daim ntawv thov scenarios.
Ua ntej tshaj plaws, qhov sib txawv loj tshaj plaws nyob rau hauv txoj kev deoxidation thiab cov khoom seem.
Ordinary ntshiab tooj liab, tseem hu ua oxygen- tooj liab dawb lossis tawv tawv tooj liab hauv kev nkag siab dav, feem ntau muaj cov pa me me, feem ntau 100-650 ppm. Thaum lub sij hawm smelting txheej txheem, oxygen yog inevitably tov nyob rau hauv, tsim tooj liab oxide nyob rau hauv lub grain ciam teb. Hauv qhov sib piv, phosphorus deoxidized tooj liab yog ib hom tooj liab tshwj xeeb uas ntxiv me me ntawm phosphorus hauv theem smelting rau kev sib sib zog nqus deoxidation. Phosphorus reacts nrog oxygen los tsim phosphorus oxide roj thiab khiav tawm, kom cov pa oxygen hauv cov tooj liab txo qis heev, feem ntau tswj tau qis dua 10 ppm. Txawm li cas los xij, ib qho me me ntawm cov phosphorus residual (feem ntau 0.005% - 0.04%) yuav nyob twj ywm hauv cov khoom tiav, uas yog cov yam ntxwv tseem ceeb tshaj plaws ntawm phosphorus deoxidized tooj liab.
Qhov thib ob, ob qho tib si sib txawv hauv hluav taws xob conductivity.
Ordinary ntshiab tooj liab muaj qhov ua tau zoo heev, ze rau 100% IACS, uas yuav luag yog qhov siab tshaj plaws ntawm cov khoom siv hlau. Yog li ntawd, nws yog cov khoom siv rau siab - kev xa hluav taws xob ua tau zoo. Cov phosphorus residual hauv phosphorus deoxidized tooj liab yuav cuam tshuam me ntsis kev khiav ntawm electrons, uas ua rau txo qis hauv conductivity, feem ntau yog li ntawm 85% -95% IACS. Txawm hais tias qhov no conductivity tseem zoo heev, nws tsis zoo li cov tooj liab ntshiab. Qhov sib txawv no ncaj qha txiav txim siab lawv qhov chaw sib txawv hauv qhov hluav taws xob.
Nyob rau hauv cov nqe lus ntawm vuam kev ua tau zoo thiab kub ua hauj lwm, phosphorus deoxidized tooj liab muaj cuab kev zoo.
Cov pa oxygen uas muaj nyob rau hauv cov tooj liab zoo tib yam yog ib qho yooj yim ua rau hydrogen embrittlement thaum lub sij hawm roj vuam, brazing los yog siab - kub cua sov. Hydrogen reacts nrog tooj liab oxide los tsim cov dej vapor, uas ua rau muaj kev kub ntxhov hauv cov khoom, ua rau tawg thiab tawg. Phosphorus deoxidized tooj liab muaj cov ntsiab lus tsis tshua muaj oxygen tom qab deoxidation sib sib zog nqus, yog li nws tuaj yeem tiv thaiv hydrogen embrittlement. Nws muaj kev ua haujlwm zoo heev, kev ua haujlwm brazing thiab kev ua haujlwm kub, thiab tsis yooj yim rau tawg thaum ua. Qhov no ua rau nws irreplaceable nyob rau hauv cov khoom uas yuav tsum tau ntau welding.
Hais txog thermal conductivity thiab plasticity, ob qho tib si zoo heev, tab sis muaj qhov sib txawv me ntsis.
Ordinary ntshiab tooj liab muaj me ntsis siab dua thermal conductivity, uas yog tsim nyog rau lub sij hawm uas yuav tsum tau meej tshav kub conduction efficiency. Phosphorus deoxidized tooj liab muaj me ntsis zoo plasticity thiab toughness nyob rau hauv qhov kub thiab txias, thiab yog haum rau khoov, flaring, extrusion thiab lwm yam complex txheej txheem.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov scenarios, ob qho kev faib kom meej.
Ordinary ntshiab tooj liab yog tsuas yog siv nyob rau hauv cov teb uas yuav tsum tau siab rau conductivity, xws li fais fab cables, busbars, motor windings, transformers, electronics connectors thiab integrated circuit lead thav ntawv. Phosphorus deoxidized tooj liab yog siv dav hauv cov kav dej, tub yees, cov kav dej roj, cov khoom siv hluav taws xob, cov dej tso tsheb hlau luam, cov khoom siv tooj liab zoo nkauj thiab lwm yam khoom uas xav tau vuam thiab tsim, vim nws muaj kev nyab xeeb thiab txhim khu kev qha hauv vuam thiab tsis yooj yim rau xau.
Hauv cov ntsiab lus
Qhov sib txawv ntawm phosphorus deoxidized tooj liab thiab tooj liab ntshiab zoo tib yam los ntawm kev kho phosphorus deoxidation: zoo tib yam tooj liab ntshiab tsom rau ultra-siab conductivity, thaum phosphorus deoxidized tooj liab tsom rau kev ua tau zoo vuam zoo thiab tsis tshua muaj oxygen stability. Kev xaiv cov khoom siv tshwj xeeb yog nyob ntawm seb cov khoom puas tseem ceeb rau cov khoom siv hluav taws xob lossis vuam thiab kev ua haujlwm.
