I. Repair Methods for Wear and Tear on the Edges of a PVC Conveyor Belt
1. Small Damage Repair (Scratches or holes <3cm in diameter):
Clean the damaged area and roughen the edge by 3-5cm with 80-120 grit sandpaper.
Apply special PVC glue or polymer repair material, smooth it out, and let it cure for 2-4 hours.
2. Large Crack Repair (Length >5cm, Width >1cm):
Expand the sanding area to 5-8cm and clean off any dust.
Cover with repair material and apply pressure (3-5kg), allowing it to cure for 4-6 hours.
3. Quick Emergency Repair:
Use belt adhesive strips (such as those popular on Taobao) directly and press firmly for a few minutes to restore operation.
II. Post-Repair Precautions
1. Check if the repaired area is flat. Run the belt unloaded for 10-15 minutes before gradually loading.
2. Avoid contact with sharp materials or heavy loads in the short term.
III. Measures to Prevent Edge Wear
1. Equipment Adjustment: Calibrate the parallelism of idlers and rollers to prevent misalignment.
2. Material Control: Remove sharp foreign objects and avoid uneven loading.
3. Regular Maintenance: Inspect belt wear and promptly address minor damage.
