Zinc Dust

Another name Zinc PowderMolecular formula ZnCAS No : 7440-66-6Characteristics Gray Powder Molecular weight : 65.38 Gravity : 7.14 Specific gravity : (g/cc) : 2.8 - 3.2 PH : 6.95 - 7.37 Melting point : 419? Boiling point : 907? Solubility : Soluble in acid, alkali, Insoluble in water It protects the inside by making the film of basic carbonate out of the air It generates ZnO and H2 by reacting slowly to moisture Application No. Use Main Functions 1 Anti-rustpaints Zinc has excellent anti-rust quality and so, it is used for painting the surface of metal structures such as vessel, container after making paints which mixed zinc-dust with binder resin 2 Substitution agent 1) It is added to substitute, precipitate, clear the impurity when silver or zinc is smelted 2) It is used for substitution agent to clear the heavy metal such as Fe, Mn, Cu when    sewage treatment 3 Reducing agent It is used for the reducing agent to combine oxygen in organic reaction, the intermediate of dye stuff 4 Other Use Medicine, Paints etc Specification Grade EMP UMP SMP SP Total Zinc(%)Metallic Zinc(%)Lead(%)Cadmium(%)Iron(%)Arsenic(%)Specific Gravity325 Mesh(44? +)%Mean Partical Size(?s) 99.0 Min96.0 Min0.2 Max0.1 Max0.05 Max- 7.1 Max0.02 Max2.5-3.5 99.0 Min96.0 Min0.2 Max0.1 Max0.05 Max- 7.1 Max0.02 Max3.5-4.5 99.0 Min96.0 Min0.2 Max0.1 Max0.05 Max- 7.1 Max0.03 Max4.5-5.5 99.0 Min96.0 Min0.2 Max0.1 Max0.05 Max- 7.1 Max0.05 Max6-12 Packing Unit Classification Unit weight Packing Style Zinc-Dust 20 - 50kg100, 400kg500, 600, 1000kg CanDrumPP Woven Bag
