Kev siv cov tooj dag thiab tooj liab rods

Kev siv Brass Rods
1. Nws tuaj yeem siv rau txhua yam kev kos duab sib sib zog nqus thiab khoov qhov chaw, xws li pins, rivets, washers, txiv ntseej, conduits, barometers, cov ntxaij vab tshaus, radiator qhov chaw, thiab lwm yam.
2. Nws muaj lub tshuab ua haujlwm zoo, zoo heev plasticity nyob rau hauv lub xeev kub, siv tau plasticity nyob rau hauv lub xeev txias, zoo machinability, yooj yim vuam thiab vuam, thiab corrosion kuj.Nws yog ib hom tooj dag uas feem ntau siv.

Kev siv tooj liab rods
1.1.Kev siv cov pas nrig tooj liab yog dav dua li cov hlau ntshiab.Txhua xyoo, 50% ntawm tooj liab yog electrolytically purified rau ntshiab tooj liab, uas yog siv nyob rau hauv kev lag luam hluav taws xob.Cov tooj liab liab tau hais los ntawm no tiag tiag yuav tsum yog cov ntshiab heev, nrog cov ntsiab lus tooj liab ntau dua 99.95%.Ib qho me me ntawm impurities, tshwj xeeb tshaj yog phosphorus, arsenic, txhuas, thiab lwm yam, yuav txo tau qhov conductivity ntawm tooj liab.
2. Cov pa oxygen hauv tooj liab (ib qho me me ntawm cov pa oxygen yooj yim sib xyaw hauv tooj liab smelting) muaj kev cuam tshuam zoo rau hluav taws xob conductivity.Tooj liab siv hauv kev lag luam hluav taws xob feem ntau yuav tsum yog tooj liab tsis muaj oxygen.Tsis tas li ntawd, impurities xws li txhuas, antimony, thiab bismuth yuav ua rau cov crystals ntawm tooj liab tsis tuaj yeem ua ke ua ke, ua rau kub brittleness thiab cuam tshuam rau kev ua cov tooj liab ntshiab.Qhov no high-purity ntshiab tooj liab yog feem ntau refined los ntawm electrolysis: siv impure tooj liab (uas yog, blister tooj liab) raws li cov anode, ntshiab tooj liab li cathode, thiab tooj liab sulfate tov raws li cov electrolyte.Thaum qhov tam sim no dhau mus, cov tooj liab tsis huv ntawm lub anode maj mam yaj, thiab cov tooj liab ntshiab maj mam precipitates ntawm cathode.Cov tooj liab tau los ntawm txoj kev no;purity tuaj yeem ncav cuag 99.99%.
