It is applicable to the surface treatment of small household appliance shells and internal components, helping to improve the surface finish and meet the appearance standards of finished products.
The grinding disc must be used with a hand polishing machine, and the operating speed should not exceed 3000RPM to avoid safety hazards.
Operators should wear professional protective equipment, including goggles and dust masks, to prevent abrasive dust from entering the eyes and respiratory tract.
Select the appropriate hardness (5P–12P) according to the workpiece material. Soft materials are suitable for low-hardness discs, and hard materials are suitable for high-hardness discs.
Store the unused grinding discs in a dry and ventilated environment to prevent moisture from affecting the adhesive performance.
