The effect of temperature on the performance of the sling: Because the sling material is a chemical synthetic fiber, the excessive temperature is terrible destructive to the synthetic fiber sling. Especially in places where there is welding operation, it is necessary to prevent sparks from squeezing the sling. The round sling has a temperature range of -40°C to 100°C.
The effect of acid and alkali on the performance of the sling: Acids can affect the properties of nylon and even completely destroy the strength of nylon; many acids do not affect the properties of polyester, but some acids can cause low to moderate damage to polyester. Many bases do not affect the properties of nylon, but some bases can cause low to moderate damage to nylon; alkalis can affect the properties of polyester and even completely destroy the strength of polyester; when using synthetic fiber slings in acid and alkali applications
The following factors should be evaluated first: the type of acid, alkali or other chemical; the extent of acid-base exposure, concentration
Ultraviolet rays can destroy the strength of synthetic fiber slings. It is recommended to use the following methods to avoid the effects of ultraviolet light or arc welding: when not in use, store the slings in a ventilated, cool, dry place; check the slings one or more times per week depending on the sling usage. Visual inspection of the extent of UV damage: fading with color fading; sling material hardening; surface wear on areas where the sling does not often contact the load. Contact the manufacturer to test the slings that are continuously exposed to UV light.
So the effect of temperture,acid,alkali and Ultraviolet rays should be taken into consideration when we using the lifting webbing,round slings.
