前几年,由于电解二氧化锰在国内外市场走俏,不少地区和单位纷纷新建电解二氧化锰装置,有的电解金属锰厂家也转产电解二氧化锰。最近两年内,国内电解二氧化锰生产厂家已由过去的7个增加到20多个,年生产能力由1.6万t锰增到3万t以上,使生产出现了过剩。以四川省为例,原来只有重庆化工厂一家生产电解二氧化锰,生产能力只有2500t;近两年在武隆、彭山、城口、大邑、都江堰等地新上了6
A few years ago, due to the popularity of electrolytic manganese dioxide in the domestic and foreign markets, many regions and units have newly built electrolytic manganese dioxide plant, and some electrolytic manganese manufacturers also converted electrolytic manganese dioxide. In the recent two years, the number of domestic manufacturers of electrolytic manganese dioxide has increased from 7 in the past to more than 20, and its annual production capacity has increased from 16,000 tons of manganese to over 30,000 tons, causing an excess of production. Taking Sichuan Province as an example, only Chongqing Chemical Plant produced only electrolytic manganese dioxide with a production capacity of only 2,500 tons. In the past two years, Wulong, Pengshan, Chengkou, Dayi and Dujiangyan have newly built 6
