With the implementation of speeding up of railway transportation, railway subgrades are also constantly applying new technologies, new materials and new processes to meet the needs of speeding up trains. What is the performance of high-speed rail reinforced pA6 plastic? Let's take a look!
The plastic casing reinforced with pA6 plastic is embedded in the concrete switch sleeper according to the set position and technical requirements during the production of the concrete switch sleeper, which is used for the assembly and connection of the switch sleeper and the rail.
This technology eliminates the traditional on-site sulfur anchoring process, improves on-site operation efficiency, and overcomes the hole nail crack defect of sulfur anchoring. High-speed rail reinforced pA6 plastic meets the requirements of high-speed train passing at turnouts, ensuring train operation Safety.
Reinforced pA6 plastic for high-speed rail generally uses glass fiber as a reinforcing material. Even after adding more glass fiber, the PA solution can still maintain good fluidity. Because the tensile strength of reinforced pA6 plastic itself is low, only 60-80MPa, adding glass fiber to PA66 matrix can improve the tensile strength of PA66.
Generally, elastomers are used as toughening agents to toughen them. When the elastomer content is 20% -25%, reinforced pA6 plastics have better mechanical properties.
