Kev lag luam kev loj hlob ntawm Tuam Tshoj lub siab purity alumina kev lag luam hauv 2021

Raws li Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Lag Luam Kev Lag Luam ntawm Tuam Tshoj lub siab purity alumina kev lag luam (2021 Edition) tso tawm los ntawm Limu cov ntaub ntawv kev sab laj, siab purity alumina muaj qhov zoo ntawm cov hardness siab, siab zog thiab kub tsis kam, thiab yog dav siv hauv electronics, semiconductor thiab lwm yam kev lag luam.High purity alumina yog tsuas yog siv los ua ceramic substrates rau kev sib xyaw circuits thiab automotive sensors.Nws yog ib qho ntawm cov khoom siv tshaj plaws.

在中国,国内很多高纯氧化铝企业的标称产能都在数千吨左右。事实上,它们大多集中在荧光粉等低端市场。但国内部分企业纯度已达到4n5以上,在纯度上与国外龙头企业没有差距。在蓝宝石衬底方向的应用可实现进口替代。但在粒径方面,国外企业可以做到30nm(nm)以下,与国内大部分企业还有一定差距。因此,目前锂电池隔膜用氧化铝主要由住友化学等国外厂商提供。

Nyob rau hauv daim ntawv thov sapphire teb, domestic high-purity alumina ntau lawm tuam txhab uas muag muaj cuab kev ua tau zoo tus nqi zoo thiab nyob ze rau cov neeg muas zaub nyob rau hauv lub cheeb tsam, uas yuav undoubtedly muaj zoo zoo.Nyob rau tib lub sij hawm, nyob rau hauv lub teb ntawm high-end high-purity alumina, nrog rau kev vam meej ntawm domestic tuam txhab uas muag 'technology, domestic tuam txhab uas muag nrog ua technology thiab siab nqi kev ua tau zoo yuav sai sai paub ntshuam hloov, thiab nkag mus rau lub thoob ntiaj teb kev lag luam export siab. - purity alumina.

由于国内高纯氧化铝市场高端进口垄断,低端饱和,高纯氧化铝替代进口,满足国内市场需求将是发展趋势。

Txoj kev loj hlob ntawm high purity alumina kev lag luam nyob rau hauv Tuam Tshoj yog kuj lig thiab tseem nyob rau hauv nws cov me nyuam mos.Tam sim no, cov txheej txheem tseem ceeb yog txhim kho Bayer txheej txheem.Nyob rau theem no, cov khoom siv hauv tsev feem ntau yog 4N alumina, thiab muaj ob peb lub lag luam hauv tsev uas tuaj yeem tsim cov khoom 5N.Nyob rau hauv 2019, cov zis ntawm Tuam Tshoj lub high-purity alumina kev lag luam yog 7600 tons, qhov kev thov yog 15700 tons, thiab net ntshuam mus txog 8100 tons.Nyob rau hauv 2020, cov zis ntawm Tuam Tshoj lub high-purity alumina kev lag luam yog 8280 tons, qhov kev thov yog 17035 tons, thiab net ntshuam mus txog 8750 tons.

山东展驰新材料有限公司(上海晨旭贸易有限公司)生产的5N 99.999高纯氧化铝,填补了国内技术空白,打破了国外技术垄断。
