High Purity Copper Raw Cov ntaub ntawv nrog 5n thiab 6n purity los ntawm Professional Factory

1. Poob qhia txog kev siab zoo pear tooj liab cov ntaub ntawv

6N super high purity electrolytic tooj liab cov ntaub ntawv yog hais txog tooj liab nrog nws cov tshuaj purity ncav 99,9999% (5N) thiab cov roj ntsiab xws li C, N, O, H thiab S ua raws li kev xav tau ntawm semiconductor, raws li kev soj ntsuam ntawm tsawg kawg 40 piam thaj . Tam sim no Guoxi Ultra-ntshiab tshiab khoom Co., Ltd. tau ua tiav lub teb chaws loj tshaj plaws industrialized ntau lawm kab ntawm 6N super siab purity copper peev uas ua tau ntawm 100 ton / xyoo, qhov tsuas enterprise realizing ruaj industrialized batch zus tau cov 6N super siab purity tooj liab cov ntaub ntawv. Nws cov khoom ua ntej siv rau hauv kev tsim cov khoom siv hauv tsev loj thiab cov khoom siv evaporation, txhawm rau txawv teb chaws monopoly ntawm super high purity raw khoom siv hauv kev lag luam hauv tshuab hluav taws xob.

2. Cov txiaj ntsim ntawm cov ntaub qhwv ntsej zoo siab khov kho

High purity copper raw cov ntaub ntawv, nws yog tsim los ntawm kev ncaj ncees ntawm cov ntaub ntawv, nws yog tsim byelectrorefining 4N (99.99%) tooj liab cathode kom tau ultra purity 6N (99.9999%) copper billets, thiab cov khoom ua ntawm siab purity copper yog dav siv nyob rau hauv semi-conductor, hnub ci, thiab cov txheej txheem khoom noj khoom haus kev lag luam. Nws yuav siv tau raws li cov ntaub ntawv raw ntawm sputtering lub hom phiaj, kom paub meej tias tooj liab purity. Thiab lwm daim ntawv thov yog nyob rau hauv kev sib tsoo hlau ntawm semi-neeg xyuas, raws li tus nqi kub nce hnub hnub los ntawm hnub, lub 6N siab purity tooj liab hlau tau zoo coj qhov chaw kub xaim.
