What are the main components used in the construction of bonded abrasives?
Abrasive grains – usually aluminum oxide or silicon carbide Bonding agent – usually a resin bond Spacing of grains within the bond – determine porosity and strength
Brown Fused Alumina FEPA Size
Brown Fused Alumina FIPA size sand is made of high-grade bauxite, mixed with iron filings and carbon (anthracite) and smelted in an electric arc furnace at a high temperature of more than 2000 degrees. After full cooling and crystallisation, it is broken, shaped, magnetic separated and screened into various particle sizes. The general particle size are F4, F5, F6, F7, F8, F10, F12, F14, F16, F20, F22, F24, F30, f36, F40, F46, f54, F60, F70, F80, f90, F100, F120, F150 F180、F220、F230、F240、F280、F320、F360、F400、F500、F600、F800、F1000、F1200. There is a certain correlation between its chemical composition and particle size.
Brown Fused Alumina FEPA Size（FAQ）
How do i prevent moisture contamination in the abrasive?
Moisture contamination is the number one reason customers call Technical Support. Fortunately, it is usually preventable. There are 4 key ways to keep your abrasive free of moisture:1.Store abrasive properly and always make sure bottles are tightly closed when not in use.2.Keep abrasive in a cool dry location with minimum
What are the three basic raw materials used in the manufacture of coated abrasives?
Grain – a synthetic or natural abrasive; Bond – an adhesive that permanently bonds the backing to the abrasive; Backing – a backing that the abrasive is bonded to
What is the d50 value?
The d50 indicates the mean particle size. d50 means that 50% of particles fall within the specified grain size.
What is fepa and what does it do?
FEPA is the Federation of European Producers of Abrasives. Its mission is to develop and publish standards, documents and comprehensive safety instructions for the abrasive industry. Abrasive grain sizes are produced and sold according to the FEPA standard, among other things. This is to ensure that a consistent quality for
