GoldPack nickel powder
Properties: gray irregular-shaped powder, easily oxidized in moist air.
GoldPack nickel powder Uses: used for making non-iron-based alloys, preparation of high temperature, anti-oxidation materials, magnetic materials, may also be used as hydrogenation catalysts of chemical reactions.
Of nickel metal pigment as the main component, nickel powder and flake nickel powder, the former is distilled and purified by nickel carbonyl [Ni (CO) 4] steam decomposition by controlling the temperature, diluted with carbon monoxide gas to help the formation of the appropriate shape of the agent (oxygen and nitrogen) in the presence of nickel particles, and then the carbon dioxide gas to flush out the carbon monoxide and control of the particle surface oxygen content of 0.065%; the latter is of high purity carbonyl nickel powder, exist in the appropriate lubricants and liquid media the ball in a ball mill, grinding the formation of the appropriate thickness of the sheet.
Mainly used in paints and plastics conductive paint to electromagnetic interference and radio frequency interference shielding, for a variety of high gloss decorative paint and plastic instead of aluminum in aqueous systems for anti-corrosion coatings, fine particles of spherical nickel powder can be used for the conductive ink.
Industrial applications
Nickel powder of diamond tools (the quality of one of the metal matrix alloy powder): metal binding agent is to determine the key factors of quality diamond saw blades, cutter head, grinding wheels, core drill, etc. in diamond is determined, the metal-binding agents became the determining factor, cobalt powder, nickel powder can be used as the binder, but the higher the price of cobalt powder.
Diamond tool, the matrix refers to the package, the metal sintered body of diamond, the role of the matrix is dominated by diamond to make it play the role of cutting, but not prematurely fall off out. Matrix is generally composed by a variety of metallic elements low melting point metal powder as a binder, such as nickel powder.
The construction industry with the diamond drill bit, cutting discs, oil and gas mining of diamond drill bits, carbide drill matrix bonding material mostly nickel powder; metal processing, automotive, motorcycle, mechanical polishing and processing tools used most of the diamond abrasives, the matrix material were powered by nickel powder. Carbonyl nickel powder, electrolytic nickel powder and reduced nickel powder.
