1. Sharp edges; when the hoisting object has sharp edges, these sharp edges will cause destructive cuts to the
Sling. In order to protect the sling from cuts, a protective lining can be used on the sling and the quilt. between hanging objects.
UV exposure to continuous UV light destroys the strength of synthetic fiber slings;
1. It is recommended to use the following methods to avoid the influence of ultraviolet light or arc welding light as much as possible: When not in use, store the sling in a ventilated, cool and dry place; Check the sling once or several times a week according to the usage of the sling.
2. Visual inspection method for the degree of UV damage: The color of the sling is faded; The material of the sling is hardened; Surface wear occurs in the parts where the sling does not often contact the load.
3. Test Contact the manufacturer to test the sling continuously exposed to ultraviolet rays.
2. Acids: Acids can affect the properties of nylon, or even completely destroy the strength of nylon; many acids will not affect the properties of polyester, but some acids will cause low to moderate damage to polyester.
3. Alkali; many alkalis will not affect the characteristics of nylon, but some alkalis will cause low to moderate damage to nylon; alkalis will affect the characteristics of polyester, and even completely destroy the strength of polyester; use synthetic in the presence of acid and alkali When using fiber slings, the following factors should be evaluated first: The type of acid, alkali or other chemical; The degree and concentration of acid and alkali exposure.
4. Temperature: Because the raw material of the sling is a chemical fiber product, excessive temperature can damage or even be destructive to the synthetic fiber sling, especially in places with welding operations, to prevent the sparks generated by electric welding from scalding the sling.
