PTFE sliding bearing pads are produced using two distinct methods, each with unique advantages in terms of efficiency and structural integration. The first method involves separate production of the rubber bearing and PTFE plate, where grease pits are pressed into the PTFE using a mold before bonding it to the rubber bearing. The second method integrates the PTFE plate during the rubber bearing's vulcanization, pressing grease pits directly into the PTFE without needing a separate mold. Both methods leverage PTFE's exceptional properties, such as low friction and high compressive strength, to ensure durability and performance in demanding applications like bridge construction.
Key Points Explained:
-
Separate Production and Bonding Method
- Process: The rubber bearing is manufactured first. A custom mold is then used to press grease pits into the ptfe sliding pads plate, which is later bonded to the rubber bearing.
-
Advantages:
- Allows precise control over the PTFE plate's grease pit design.
- Simplifies quality inspection at each stage (rubber bearing and PTFE plate).
- Considerations: Requires additional steps for bonding, which may increase production time.
-
Integrated Vulcanization Method
- Process: The PTFE plate is incorporated during the rubber bearing's vulcanization. Grease pits are pressed into the PTFE simultaneously, eliminating the need for a separate mold.
-
Advantages:
- Reduces production steps by combining processes.
- Enhances structural integrity due to direct integration.
- Considerations: Less flexibility to modify grease pit patterns post-production.
-
Material Properties Driving Method Selection
- PTFE's low coefficient of friction (critical for sliding performance) and high compressive strength (up to 200 Kgf/cm²) make it ideal for bearing pads.
- Both methods ensure PTFE's resistance to chemical/environmental degradation is preserved.
-
Application Context
- Used in large-span bridges where shear capacity, shock absorption, and load distribution are critical.
- Installation methods (bolting, welding, etc.) must protect PTFE from damage (e.g., weld spatter).
-
Trade-offs for Purchasers
- Separate Method: Better for custom designs but higher labor costs.
- Integrated Method: Cost-efficient for standardized projects but less adaptable.
Did you know? PTFE's friction decreases under pressure—making it uniquely suited for dynamic loads in infrastructure. Both methods prioritize PTFE's unparalleled performance, but the choice hinges on project-specific needs for customization versus efficiency.
Summary Table:
| Method | Process | Advantages | Considerations |
