【摘要】 以次硫酸氢钠甲醛副产锌泥为原料,用高剪切乳化机乳化锌浆,采用双氧水作为氧化剂氧化锌浆中的金属锌使之转化为氢氧化锌,采用二氧化碳作为沉锌剂碳化锌浆后得到碱式碳酸锌沉淀,沉淀通过脱水、洗涤、干燥、煅烧后可得到活性氧化锌产品。该方法充分利用了锌资源,有效处理了大量闲置的锌泥,制得的活性氧化锌产品质量可达到HG 2572—1994合格品标准。更多还原

【Abstract】 Taking the by-product zinc mud from the production of sodium formaldehyde sulfoxylate as raw material,dissolving the zinc mud by emulsifer,converting the zinc into zinc hydroxide by using H₂O₂ as an oxidant,then the basic zinc carbonate precipitate is obtained by using CO₂ as a precipitator.Through dehydration,washing,drying and calcining,the active zinc oxide is got and its quality can reach the standard of HG 2572—1994.This method is a good way for utilizing zinc resources and treating the zinc mud.更多还原
