Electrolytic manganese dioxide

Main purpose: Electrolytic manganese dioxide is an excellent battery depolarizing agents, it is compared with the production of natural manganese dioxide discharge batteries, it has a discharge capacity, activity, small size, long life and other characteristics, mixed with 20- 30% EMD made all with natural MnO2 battery than batteries made its discharge capacity increase by 50-100%, 50-70% EMD mixed with zinc chloride in high-performance battery, the discharge capacity can be increased 2-3 times, all with EMD made alkaline manganese batteries, the discharge capacity can be increased 5-7 times, so electrolytic manganese dioxide battery industry has become a very important raw material. In addition to the physical state of electrolytic manganese dioxide batteries as the main raw material, but also widely used in other areas, such as: fine chemical production process as an oxidizing agent, Mn-Zn ferrite soft magnetic materials in raw materials. Because of electrolytic manganese dioxide has a strong catalytic, oxidation / reduction, ion exchange and adsorption capacity, after treated with forming a water filter excellent overall performance, with the usual use of activated carbon and zeolite net Compared to the water filter, have a stronger ability to discoloration and removal of metal P-type electrolytic manganese dioxide No. Item Technical indicators are currently SPEC 1 manganese dioxide (MnO2) ≥ 91.0% 92.33% 2 water (H2O) ≤ 3.0% 2.17% 3-iron (Fe) ≤ 100ppm 65 ppm 4 copper (Cu) ≤ 5ppm 0.5 ppm 5 lead (Pb) ≤ 5ppm 0.5 ppm 6 of nickel (Ni) ≤ 5ppm 2.0 ppm 7 cobalt (Co) ≤ 5ppm 2.0 ppm 8 Mercury ( Hg) ≤ 50ppm 47ppm 9 hydrochloric acid insoluble matter ≤ 0.10% 0.01% 10 Sulfate ≤ 1.4% 1.2% 11 PH value (distilled water method) 5.5 to 7.5 6.5 12 -100 mesh particle size ≥ 99.5% 99.9% -200 mesh ≥ 95.0 % 92.0% -325 mesh ≥ 90.0% 95.0% mercury-free alkaline electrolytic manganese dioxide No. Item Specifications 1 sample product manganese dioxide (MnO2) 92.2% 2 water (H2O) 1.7% 3 iron (Fe) 48.5 ppm 4 copper (Cu) 0.5 ppm 5 lead (Pb) 0.5 ppm 6 of nickel (Ni) 1.41 ppm 7 cobalt (Co) 1.2 ppm 8 molybdenum (Mo) 0.2 ppm 9 arsenic (As) 0.2 ppm 10 antimony (Sb) 0.2 ppm 11 K ( K) 170 ppm 12 Mercury (Hg) 5 ppm 13 14 HCl insolubles 0.01% sulfate 1.22% 15 PH value (Determination of distilled water) 6.65 16 pipetting 1 ml 17 volume specific surface area of ??28 m2 / g 18 1.70 19 depends on the proportion of particles -100 mesh -200 mesh 92.0% 99.9% 95.0% -325 mesh
