Flap disc is made of plastic or fiber glass backing pads and abrasive cloth, mainly used for polishing in industrial production, also belongs to a kind of industrial consumable products. There are advantages and disadvantages of the performance of flap disc, then what are the factors that affect the performance of flap disc?
1, Abrasive: abrasive is the manufacture of flap disc is an important raw material, it is responsible for cutting work. Therefore, the abrasive should be sharp, with high hardness, good heat resistance and positive toughness.
2. Hardness: the hardness of flap disc refers to the difficulty level of the abrasive grains on the surface of flap disc falling off under the action of grinding force. flap disc hardness is low, performance flap disc abrasive particles easy to fall off, flap disc hardness is high, performance abrasive particles more difficult to fall off. Hardness and abrasive hardness are two different concepts.
3. Grit size: grit size refers to the size of abrasive grain. The grit size is divided into two categories: grinding grain and micro powder.
4. Combination agent: the material used to bond the abrasive in the emery cloth wheel is called combination agent. The strength, impact resistance, heat resistance and corrosion resistance of the grinding wheel depend on the properties of the combined agent.
The same kind of abrasive can be made into flap disc with different hardness, which depends on the properties, number of joint agents and the manufacturing process of grinding wheel.
