Our high-performance EP coated paper making doctor blade is specially developed for continuous, high-load and high-speed operation of global paper mills. Adopting advanced modified EP composite coating technology, the coating is tightly combined with the blade substrate with ultra-high adhesion, uniform density and zero porosity. Compared with ordinary blades on the market, our EP coating features superior structural stability, effectively avoiding common defects such as coating peeling, edge wear, pulp sticking and chemical corrosion. It maintains stable mechanical performance under long-term high humidity, dust erosion and complex chemical medium environments, delivering consistent scraping, cleaning and paper separating effects. The excellent anti-fouling, wear-resistant and anti-aging properties greatly reduce paper defects, avoid frequent shutdown maintenance, and ensure long-term stable operation of paper machine systems, which is the ideal durable consumable for high-standard paper production lines.
This series of doctor blades supports full-specification customization and covers complete size ranges to adapt to all types of international paper machine models and different production processes. We provide abundant standard and non-standard dimension options, including conventional sizes: length 500mm–8000mm, width 20mm–120mm, thickness 1.0mm–6.0mm. Meanwhile, customized ultra-long, ultra-thin, widened and special-shaped blades are available for special equipment and special working conditions. All core parameters can be precisely tailored, including coating thickness, coating hardness, blade edge angle and surface roughness. Whether for tissue paper, cultural paper, kraft packaging paper or special paper production, our customized blades achieve precise fitting, clean scraping, no paper breaking and no roller scratching. With strong versatility, high fitting accuracy and ultra-long service life, our products effectively lower comprehensive operating costs and create stable production benefits for global paper manufacturing enterprises.
