Polyester fiber lifting belt in addition to the information identification can be through the color to identify its rated load, different color represents different rated load lifting belt, which is the international standard, its main purpose is to prevent information loss of identity, but the color of the lifting belt appear fade under the influence of various factors, too, so what reason is caused, lifting belt of fade? Chenghua manufacturing below from a number of aspects for you to analyze.
1. The lifting belt has hydrolysis and oxidation reaction due to the action of sunlight and water for a long time, which will lead to the fading of the lifting belt and the deterioration of the performance of synthetic fiber.
2. There are residues that affect synthetic fibers, such as the hardening effect of residual chlorine.
3. The lifting belt becomes yellow due to the deterioration of finishing agent such as fluorescent whitening agent.
4, as a result of the quality of the pigment itself, the sublimation of dye caused by fading dyed fabric.
5. Discoloration of lifting belt due to oxidation of oil agent and evaporation of residual solvent.
Once the hoisting belt has faded, users will not be able to intuitively identify the rated load of the lifting belt, but this is not the point. The point is that once the hoisting belt has faded, its performance is changing, and in this case, the safety factor of the hoisting belt will decline sharply. Therefore, it is recommended to pay attention to the storage of the lifting belt at ordinary times, try to store it in a cool and ventilated environment, so that the lifting belt is always bright in color and the safety factor is always the same
