Main Purpose: Vehicle Alumina powder commonly pornographic layer analysis of vehicle. Manufacturing tempered glass Alumina is an aluminum metal in the air is not easy to corrosion reasons. Aluminum oxide film covering pure aluminum easily with oxygen in the air reacts in a thin layer of aluminum surface exposed to air. This layer of aluminum oxide film to prevent oxidation of the aluminum is continuing. Processing and properties of the oxide film thickness can be called by anodization (anode corrosion) has been strengthened. Applicable range of industries: aerospace, automotive industry, consumer goods, processing, casting / die casting, OEM distributors, the semiconductor industry and other various fields. Applicable range of technology: surface plating, painting, glazing and coating polytetrafluoroethylene before pretreatment; and aluminum alloy products, deburring, boiler scale; mold cleaning; metal substrates before blasting; dry and wet; precision optical refraction; minerals, metals, glass and crystal grinding; glass sculpture and paint additives.
