1. Generally used and stored at temperatures greater than 5℃ and less than 40℃;
2. Keep away from moisture and dampness. Store the environment relative humidity is less than 65%, the best dryer (ventilation, dehumidifier, air conditioning, etc.). In the preservation to ensure that all coated abrasives do not directly contact the cement floor, away from moisture, heat source;
3. The storage time is 6 months.
Requirements for use:
1. Suspension shall be carried out before use to restore abrasive belt to its natural state. However, the suspension time should not be too long in wet season or when the temperature is high.
2. Before starting the machine, the appearance quality of sand belt shall be checked, and the surface of abrasive belt shall be checked for defects, bumps, broken marks or other defects; Check whether the joint of abrasive belt is balanced, whether there is an opening phenomenon, whether there is a prominent joint glue block on the back of the joint, whether there is a fracture phenomenon on the edge of abrasive belt; Whether the size on the label and packing case is in conformity with the required size; For precision polishing, it is recommended to check the joint thickness of abrasive belt.
3. The installation shall be performed according to the operating standards of the belt sander. After loading on the machine, it should start empty operation under low tension pressure, and gradually increase to working tension after smooth operation of the belt.
4. The linear speed of the belt should be controlled within the range of 15-35m/s. Please do not overspeed.
5. The allowable range of broken belt is 2%.
4, according to the material of the workpiece to be processed to choose the appropriate cutting parameters (cut thickness) and remove the size of the margin to choose the particle size, but also can improve the service life of sand belt. For multichannel sanding, a reasonable combination of particle size (number and number) is the best way to obtain the effect.
5. If there is life difference between each batch, please check the process problem according to the above conditions. The choice of belt is suitable for the final surface value (finish, decorative grain, roughness) is the standard.
