General Introdaction
Advanced multi-material coatings revolutionize industrial roller in papermaking, offering tailored solutions for critical components like center press rollers, Yankee dryers, rewinder base rollers, and dryer cylinders.
Engineered with high-performance materials such as oxide ceramics, tungsten carbide, and Teflon composites, these coatings deliver exceptional hardness (up to 1400 HV0.3), corrosion resistance (pH 3-10), and anti-stick properties.
By optimizing surface roughness, wear resistance, and blade compatibility, they significantly reduce downtime, extend equipment lifespan, and enhance paper quality-ensuring reliable, cost-effective performance across diverse papermaking processes.
