    What are the factors that affect the performance of flap disc?

    The flap disc, also known as the flap wheel, elastic grinding disc, is made of plastic, fiberglass backing, etc., which is a kind of coated abrasive.

    The flap disc is suitable for the welding of the weld in the box body and the burr of the stamping part. It is used for grinding and polishing various stainless steel and carbon steel structural parts. The performance of the louver is not uniform. What are the factors that determine the performance of the flap disc?

    1. Abrasive: Abrasive is an important raw material for the manufacture of grinding wheels, mainly responsible for cutting work. Therefore, the abrasive must be sharp and have high hardness, good heat resistance and stable toughness.


    2. Particle size: Particle size refers to the thickness of the abrasive grain size. The particle size is divided into two types: abrasive grains and fine powder.

    1 abrasive having a particle size greater than 40 μm, referred to as abrasive particles;

    2 Abrasives with a particle size of less than 40 μm, called micropowder.

    In general, the finer the abrasive grain size, the better the surface roughness of the grinding.

    3. Bonding agent: The substance used to bond the abrasive in the grinding wheel is called a binder. The strength, impact resistance, heat resistance and corrosion resistance of the grinding wheel depend largely on the properties of the bonding agent.


    4. Hardness: The flap disc refers to the difficulty of the abrasive grains falling off under the action of grinding force. The hardness of flap disc soft, the abrasive grain is easy to fall off; the hardness is hard, and the abrasive grain is difficult to fall off.

    The hardness of the flap disc and the hardness of the abrasive are two different concepts.


    As a polishing and polishing tool, the flap disc has brought great convenience to industrial manufacturing. At present, the market consumption of flap disc is still huge, and it is expected to continue to rise every year in the future.
