The flow-passing components of these equipment are subjected to intense erosion and corrosion, such as the induced draft fans in dust removal systems and the blowers in pneumatic conveying systems. Since these fans operate in dust-laden airflow, the dust particles in the airflow not only cause wear on the fan but also accumulate ash on the fan blades, and both the wear and ash accumulation are uneven. This disrupts the balance of the fan rotor, causing vibration, shortening the fan's service life, and in severe cases, rendering the fan inoperable. In particular, the wear on fan blades is the most severe, as it not only disrupts the flow characteristics inside the fan but also easily leads to major accidents such as blade breakage and overspeed. Qingdao Yuke New Material Company's EG20 ceramic-metal technology originates from Germany and is primarily used for wear-resistant repair, cast lining, and energy-saving anti-corrosion in pumps and fans. EG20 ceramic-metal product is a composite material mainly composed of high-hardness silicon carbide (SiC), nano-alumina (Al2O3), and silicon dioxide (SiO2), high-strength Kevlar fibers, and bisphenol A/F epoxy resin. After mixing with a curing agent, it polymerizes and cures at room temperature, forming strong bonds with various substrates such as metal, rubber, and plastic. It provides extremely high wear resistance, impact resistance, crack resistance, corrosion resistance, and more. The EG repair technology employs a "cold welding" method, which does not cause thermal stress changes, allowing repaired components to be assembled smoothly. Repairing worn fans can result in wear resistance that is more than 5 times greater than the original metal material. EG20 enables rapid repair of damaged components, completing the process within 1 week, saving customers both time and money.
