In the context of fabric expansion joints, the term "fabric skin" typically refers to the outermost layer of the expansion joint, which serves as a protective barrier against external elements like heat, chemicals, and mechanical damage. This layer is crucial for the durability and performance of the expansion joint.
1.Material Composition: It is often made from high-temperature-resistant materials such as PTFE (polytetrafluoroethylene), fiberglass, or silicone-coated fabrics. The choice of material depends on the operating environment and required resistance to heat, chemicals, or UV exposure.
2.Protective Function: The fabric skin protects the inner layers of the expansion joint from environmental factors like abrasion, chemical exposure, and high temperatures.
3.Flexibility and Strength: It is designed to be flexible enough to accommodate the movements of the expansion joint while providing the necessary strength and durability.
Fabric skin is used in various types of fabric expansion joints found in industries such as power plants, petrochemical, cement, and steel industries. It helps ensure the longevity and proper functioning of the expansion joint, even in challenging conditions like high temperatures, corrosive environments, and dynamic mechanical movements.
