1.Physical and chemical properties
High-temperature resistance: The long-term operating temperature can reach 1300-1600ºC, and it has excellent thermal shock resistance.
High porosity: Open porosity 60-80%, large specific surface area (customizable), low fluid resistance.
Chemical inertness: Resistant to acid and alkali corrosion, suitable for harsh chemical environments.
Mechanical strength: Compressive strength 20-50MPa, suitable for high-pressure or vibration scenarios.
2. Main Functions
High-efficiency filtration and catalysis: Capture particulate matter and serve as a catalyst carrier (such as SCR denitrification, VOCs purification).
Heat exchange and energy conservation: Used in regenerative thermal oxidizer (RTO/RCO) systems to recover waste heat. Gas distribution and diffusion: Evenly distribute fluids to enhance reaction efficiency.
