Since the use of Flap Discs has higher requirements for safety and performance, special attention should be paid to the storage and custody of the Flap Discs.
The external environment should be kept dry and ventilated, and the temperature change should be small, and the room temperature should not be lower than 5 degrees. The vitrified bond grinding wheel cannot be placed in a wet or frozen place, the resin bond grinding wheel cannot be in contact with acid and alkali, and the two kinds of Flap Discs and the rubber bond grinding wheel cannot be in contact with oil.
Thin slices of Flap Discs with sharp edges should be stacked together, and the interval between each piece of grinding wheel should be separated by a pad (thick cardboard or foam that can maintain a certain strength).
Because the magnesite (magnesium oxide) bond of the grinding wheel can absorb moisture in the air, special care should be taken to prevent heat and erosion in the storage of this kind of grinding wheel.
Rubber bond, magnesite bond and resin bond should not be stored for too long, otherwise it will cause aging problems due to changes in chemical composition. The storage period of rubber and resin bond is generally not more than one year. After the expiry date, it is necessary Can only be used after re-inspection.
