Description： UHMW-PE (Ultra-High Molecular Weight Polyethylene) Sliding Sheet is a specialized product primarily used for bridge bearings. It is designed to provide smooth and low-friction movement between structural components, allowing for the controlled displacement and rotation of the bridge during various environmental conditions and loadings. The UHMW-PE material used in these sliding sheets possesses exceptional properties that make it well-suited for bridge bearing applications. It is a high-density thermoplastic polymer with an extremely high molecular weight, resulting in excellent wear resistance, low friction coefficient, and high impact strength. The sliding sheet is typically manufactured in the form of rectangular panels or strips, custom-made to suit specific bridge bearing requirements. These sheets are usually fabricated in various thicknesses, depending on the load capacity and expected movements of the bridge. The UHMW-PE sliding sheet is installed between the bridge superstructure and the substructure, where it acts as a sliding interface. Its primary function is to facilitate smooth movement and transfer the loads applied to the bridge. The low friction coefficient of the material ensures minimal resistance and allows for easy and controlled sliding, reducing the potential for excessive stress and wear on the bridge components.Outstanding cost advantages over conventional bridge sliding materials, especially for cold, high altitude areas. The benefits of using UHMW-PE sliding sheets for bridge bearings include: 1.Low friction: The UHMW-PE material offers an extremely low coefficient of friction, which reduces resistance and allows for smooth movement between bridge components. 2.High load-bearing capacity: Despite its low weight, UHMW-PE has a high load-bearing capacity, making it capable of withstanding heavy loads and ensuring the stability and integrity of the bridge structure. 3.Excellent wear resistance: The high molecular weight of UHMW-PE imparts exceptional wear resistance, minimizing the degradation of the sliding sheet over time and prolonging its service life. 4.Corrosion resistance: UHMW-PE is resistant to most chemicals, including water, acids, and alkalis, which helps protect the sliding sheet from corrosion and degradation, even in harsh environments. 5.Easy installation and maintenance: The UHMW-PE sliding sheets are typically pre-cut to the required size and shape, allowing for easy installation. Moreover, they require minimal maintenance due to their durability and resistance to wear. In conclusion, UHMW-PE sliding sheets are vital components in bridge bearings, enabling controlled movement and load transfer while reducing friction and wear. Their exceptional properties, including low friction, high load-bearing capacity, wear resistance, and corrosion resistance, make them ideal for ensuring the safe and efficient functioning of bridges.
