COMPOSITION OF COATED ABRASIVES(SANDPAPER/ABRASIVE CLOTH)

Mineral sand type: Whether the material properties are suitable for the material of the workpiece to be ground.

The particle size of the ore sand: Select the coarseness or fineness according to the processing requirements and the final surface requirements.

Backing type: Select the backing type based on tensile strength and adhesion to the workpiece.

Sand planting method：

Gravity planting sand	Electrostatic sand planting

The density of the planting sand for grinding products：

Dense planting type	Sparse planting sand

Electrostatic sand planting refers to the use of a high-voltage electrostatic field and relying on the electrical properties of abrasives to make the abrasives become charged bodies and be adsorbed onto the substrate coated with a binder, forming grinding materials with excellent grinding performance.

	Alumina /A			It is suitable for processing metals with high tensile strength, such as carbon steel, cast iron, alloy steel and hard wood processing.
	Zirconia corundum /Z			It is suitable for processing metals with high toughness, such as stainless steel, titanium alloys, nickel alloys, etc.
	Ceramic corundum /SG			It is suitable for metals with high tensile strength, such as stainless steel and titanium alloy, and is more durable and has a longer service life than traditional abrasives.
	Silicon carbide /C			It is suitable for processing metals with low tensile strength and high toughness, such as non-metals like copper and aluminum, as well as materials like glass, jade, and plastics.
