Ceramic particle repair material is a high-performance composite material, which is widely used in the repair and protection of industrial equipment, pipelines, kilns, and other high-temperature, wea, or corrosive environments. Its performance characteristics mainly include the following aspects:
High wear resistance
Ceramic particles (such as alumina, zirconium oxide, etc.) have extremely high hardness (Mohs hardness can reach 8-9), far exceeding metal and ordinary concrete, and can significantly improve the wear resistance of the repair layer.
It is suitable for high-friction environments, such as mining equipment linings, inner walls of conveying pipelines, anti-skid layers of road surfaces, etc., which can extend the service life of the repaired parts.
Excellent bonding strength
It has strong bonding with the substrate (metal, concrete, stone, etc.), and it is not easy to fall off or crack after repair.
Some products are designed with special formulas to achieve effective bonding on wet or oily surfaces and have wider construction adaptability.
Strong corrosion resistance
It has good resistance to chemical media such as acids, alkalis, and salts, and is especially suitable for corrosive environments such as chemical and petrochemical industries.
Some formulas can improve the ability to resist molten metal or strong acid corrosion by adjusting the ceramic composition (such as adding zirconium oxide).
Good compression and impact resistance
Ceramic particles and cementitious materials form a dense structure with a compressive strength of more than 100MPa, which can withstand heavy objects or static loads.
Some flexible formula products have a certain toughness and can resist impact loads (such as mechanical vibration and vehicle impact) to reduce the risk of brittle fracture.
Chemical corrosion resistance
It has good tolerance to acids, alkalis, salts, organic solvents, etc., and is suitable for chemical equipment, sewage treatment tanks, and concrete component repairs in acid and alkali environments.
Ceramic particles themselves have high chemical stability, and combined with corrosion-resistant adhesives (such as epoxy resins), they can resist medium erosion for a long time.
Convenience of construction
Mostly premixed or two-component materials, easy to operate: A and B components can be mixed in a ratio of 2:1 for use, without the need for professional equipment or technical training.
Fast curing speed (curing in a few hours to 1 day at room temperature) can shorten the equipment downtime and maintenance time, especially suitable for emergency repair scenarios, supporting online repair, with no need to disassemble the equipment.
Anti-aging and durability
Ceramic particles are highly weather-resistant and not easily affected by ultraviolet rays and temperature changes. The repair layer is not easy to powder, fade, or degrade after long-term use.
It can still maintain stable performance in outdoor environments (such as roads, bridges) or long-term immersion scenarios (such as pools and pipelines).
Typical application scenarios
Industries: mines, coal, thermal power generation, cement plants, etc.
Equipment: cyclone separators, powder selectors, chutes, pipelines, pump casings, impellers, hoppers, screw conveyors, etc.
Working conditions: repair and protection of high wear and corrosion.
