Features of Silicon Carbide Repair Adhesive
As a high-performance composite material, Silicon Carbide Repair Adhesive combines the inherent properties of Silicon Carbide and the formulation optimization technology, and has the following core features:
1. Physical Performance Advantages
Wear Resistance and Impact Resistance
The high hardness (Mohs hardness 9) and low friction coefficient of Silicon Carbide give the repair adhesive excellent wear resistance, which can withstand high-speed friction and particle scouring, and significantly extend the service life of equipment such as mining machinery and mud pumps. At the same time, the optimized epoxy resin formula improves the toughness and impact resistance of the coating, reducing damage caused by external impact.
High Temperature Stability
It can withstand high temperatures above 1200°C, and some formulas can still maintain structural stability at 1600°C. The SiO₂ oxide film on its surface can slow down the high-temperature oxidation rate, which is suitable for the repair needs of high-temperature equipment such as furnaces and boilers. High thermal conductivity (3-5 times higher than ordinary materials) effectively improves the heat dissipation performance of high-temperature equipment.
2. Chemical performance advantages
Corrosion resistance and oxidation resistance
It has strong resistance to corrosive media such as acids, alkalis, and salts, such as chloride and sulfuric acid environments in petrochemical equipment. The dense SiO₂ layer formed at high temperature can prevent the spread of oxidation reactions and maintain protective effects above 1000°C.
Environmental adaptability
The non-toxic and harmless formula meets environmental protection requirements, and there are no harmful volatiles during the curing process, which is suitable for sensitive industries such as food and medicine.
3. Construction and process characteristics
Operation convenience
The two-component design (some products are nano-grade ceramic micropowders) combined with low viscosity characteristics can achieve a variety of construction methods such as brushing and spraying, with a short curing time (1-2 hours of initial curing at room temperature), reducing downtime and maintenance cycles.
Coating performance optimization
Through the particle size grading design of spherical silicon carbide micropowders, the packing density of fillers is increased, the amount of resin is reduced, and the density of the coating is enhanced, achieving the goal of high solid content and low VOC emissions. The surface has a high finish after curing, which can reduce fluid resistance and improve the efficiency of pump equipment.
Fourth, Economic Performance
The cost of a single repair is only 20-30% of traditional welding or replacement parts, and it can be repaired repeatedly, reducing the maintenance cost of the equipment throughout its life cycle.
Under extreme working conditions (such as high temperature and strong corrosive environment), the service life can be extended by 3-5 times compared with ordinary repair materials.
The above characteristics make it widely used in cement equipment, oil drilling platforms, power facilities, aerospace and other fields, becoming a key material for industrial equipment maintenance.
