800 mesh Zinkpulver

Zinc powder products seriesChemical name: metallic zinc powder Molecular formula: Zn Molecular weight: 65.38Performance: gray metallic fine powder, density 7.14g/cm3, melting point 419ºC boiling point 907ºC, dissolving in acid, alkali and ammonia water but not in water. It has strong reducibility and adhesive power. It remains stable in dry air, but tends to agglomerate in moist air and results in alkaline carbonate on the surface of the particles.Functions: Superfine zinc powder is mainly used as key raw material in zinc-rich coating,as well as in anti-corrosion, environment protection and other high performance coating. They can be widely applied in large steel structures, ship building, container industries aviation, automobile, Ordinary zinc powder can be widely applied in metallurgy,chemical industry,pharmacy,dye,battery and other areas.Transportation: Stored in dry, airy warehouse without acid, alkali and inflammables. Be cautious of moisture, water and fire during storing and transportation.Features: The zinc powder product of our company is high in the content of zinc and low in impurity. The crystal form is regular globular structure. The surface of the spherocrystal is smooth. It is large in specific surface area, small in loose density and in the area of surface oxidation. The fine powder whose grain size is smaller than 10um is high in content. The coating materials made with it as raw material is thin in paint film, small in consumption quantity, smooth in surface and strong in corrosion-resisting property. When used as reductant, it has the characteristics of stable reaction, low consumption, less foreign matter in products and by-products. The quality of all our products accords with the national standards (GB/T6890-2000). Our company can also produce all kinds of zinc powder, with different chemical components, different size distributions, ranging from 80 mesh, 400 mesh, 600mesh, 800mesh, 1000mesh to 1500 mesh to meet our clients' needs.The specification and standard of zinc powder of our company is chart 1.Chart 1: Standard for Chemical Components and Particle Size of Zine Powderchemical componentSortStandardAll ZineMetal ZincLead PbCadmium CdIron FeAcid InsolublesPremium gradeASTM D520 Type 3≥99.0≥96.0≤0.002≤0.001≤0.002≤0.01Low Pb gradeASTM D520 Type 2≥98.5≥96.0≤0.01≤0.05≤0.01≤0.03State gradeGB/T6890-2000≥98.5≥96.0≤0.1≤0.1≤0.05≤0.05Particle SizeSortSpecificationNominal Particle Size(mesh)Average Particle sizeMax SizeResidue On Sieve+200(mesh)+325(mesh)+500(mesh)Super extraWLZn-1500-15001 3≤10NoneNoneNoneWLZn-1000-10002 4≤13NoneNoneNoneSuper fineWLZn-800-8003 5≤15NoneNone≤0.01%WLZn-600-6004 6≤22NoneTrace≤0.1%WLZn-500-5005 7≤30None≤0.01%≤0.3%WLZn-400-4006 8≤38None≤0.05%-WLZn325-3257 9≤45None≤0.1%-Coarse gradeWLZn-200-200-≤75≤0.3£¥--WLZn-120-120-≤125---WLZn-800-80-≤180---WLZn-600-60-≤280---
