1. Scar

The definition of clear scar is that the surface of the covering layer has a small depression as a clear scar. The method of measuring the clear scar is to measure the large depth of the clear scar with a dial indicator or a caliper, and use a tape measure to measure the large length of the clear scar.

The rules of the open scar are planned. When the depth of the open scar on the surface of TC70 CONVEYOR BELT in china is greater than 1mm and the area is greater than 50mm², it should be repaired and perfected at one time. It should be noted that repairs are not necessary when the depth of the open scar is less than 1mm, and the depth is less than 1mm and the area is less than 50mm².

2. Gutters and cracks

The grooves and cracks are the grooves and gaps at both ends of the TC70 CONVEYOR BELT in china. Use a caliper or dial indicator to measure the depth, and a tape measure to measure the length. Defect rule planning for grooves and rips, on the belt length of each roll of TC70 CONVEYOR BELT in china, the total cumulative length of grooves and rips cannot exceed 3% of the belt length, and the individual length cannot exceed 1m, and needs to be repaired at one time. The belt side is outstanding, which refers to the part of the bulge at both ends of the TC70 CONVEYOR BELT in china. The measurement method is by hand perception and visual inspection. Problems like this should be fixed once and for all.

3. Delamination of the cover layer

Planning rules for delamination of cover layer: The delamination area on every 100m² of cover layer should not exceed 1600cm², and it should be repaired in good condition at one time.
