Tus naj npawb atomic ntawm tooj liab yog 29. tooj liab nws tus kheej yog ib qho tseem ceeb ntawm cov hlau nyob hauv cov hlau. Nws nyob qib tom qab sodium-magnesium- txhuas thiab ua ntej nyiaj -platinum. Nws belongs rau kev hloov pauv hlau. Nws muaj qhov ceev ntawm 8.92g / cm3 thiab melting point ntawm 1083.4 degree. Nws muaj qhov zoo Txawm hais tias tooj liab yog qhov ruaj khov nyob rau hauv cov nqe lus ntawm thermal conductivity thiab hluav taws xob conductivity, nyob rau hauv lub neej tiag tiag, thaum tooj liab tseem yooj yim heev rau oxidized nyob rau hauv ib tug kuj humid ib puag ncig, tooj liab oxide tshuaj yuav raug tsim tom qab kev sib cuag nrog cov huab cua ntub, uas. yog qhov peb feem ntau hais Patina, thaum cov hlau thiab cable manufacturers tsim nws, oxidation ntawm tooj liab feem ntau yuav ua rau saum npoo tig dub, thiab qhov teeb meem oxidation thiab blackening no yeej ib txwm plagued ntau hlau thiab cable manufacturers.
Yog li, puas muaj txoj hauv kev zoo los txo cov oxidation ntawm tooj liab hlau? Ua ntej ntawm tag nrho cov, nyob rau hauv lub hauv paus ntsiab lus, lub cev txoj kev yuav siv tau los thaiv lub cib fim ntawm tooj liab thiab moist huab cua. Cathodic tiv thaiv redox txoj kev tiv thaiv tooj liab conductor oxidation, tshuaj txoj kev Ib tug passivation zaj duab xis yog tsim nyob rau saum npoo ntawm tus neeg xyuas pib tooj liab los tiv thaiv oxidation, los yog ib tug tshwj xeeb kua yog sprayed rau saum npoo ntawm tus neeg xyuas pib los tiv thaiv nws. Yog li, cov kev ntsuas hauv qab no tuaj yeem siv los txo qhov tshwm sim ntawm tooj liab conductor oxidation:
1. Choose high-quality metal copper rods, standardize the supplier's transportation and delivery procedures and systems. After the copper rods arrive at the company, take transparent plastic film sealing measures, and take transparent plastic film sealing measures after copper conductors are drawn and stranded;
2. Siv cov cuab yeej siv tooj liab kom tsim nyog, tsis tu ncua xyuas qhov annealing ntawm lub tshuab nqus hlau, muab qhov tseem ceeb rau cov roj teeb uas muaj cov tshuaj tua kab mob antioxidant, tsis tu ncua xyuas cov concentration ntawm emulsion, thiab hloov nws ua ntej tas sij hawm ntawm lub txee lub neej;
3. Cov txheej txheem tooj liab stranding thiab extruding rwb thaiv tsev txheej txheem adopts passivation kho tshuab;
4. Tsim kom muaj kev paub zoo thiab ntxiv dag zog rau kev cob qhia kev lag luam kom cov neeg ua haujlwm ntawm cov txheej txheem saum toj no paub txog cov txiaj ntsig tsis zoo ntawm tooj liab hlau oxidation.
