The difference between deep carbonization and surface carbonization is mainly reflected in the depth of carbonization, process conditions, and application areas. The following is a specific comparison. If you have any equipment needs, please feel free to contact us:
1. Carbonization Depth
Deep Carbonization: The carbonization depth is large, usually throughout the entire material.
Surface Carbonization: The carbonization depth is shallow and limited to the surface of the material.
2. Process Conditions
Deep Carbonization:
Temperature: High, usually above 600°C.
Time: Long, may take hours or even days.
Environment: Strict control of oxygen-deficient or oxygen-limited conditions is required.
Surface Carbonization:
Temperature: Low, generally 200-400°C.
Time: Short, may only take a few minutes to hours.
Environment: Low requirements for oxygen control.
3. Application Areas
Deep Carbonization:
Material: Applicable to wood, biomass, etc.
Use: Used to produce high-quality biochar, soil conditioner, adsorbent, etc.
Surface carbonization:
Material: Applicable to metals, ceramics, composite materials, etc.
Use: Used to improve the surface hardness, wear resistance, corrosion resistance, etc. of materials.
4. Performance characteristics
Deep carbonization:
Uniformity: Carbonization is uniform, and the overall performance is improved.
Strength: The overall strength of the material is improved.
Durability: The durability is significantly enhanced.
Surface carbonization:
Surface hardness: The surface hardness is significantly improved.
Wear resistance: Wear resistance is enhanced.
Corrosion resistance: Corrosion resistance is improved.
5. Equipment and cost
Deep carbonization:
Equipment: A special high-temperature carbonization furnace is required.
Cost: High, due to high energy consumption and time costs.
Surface carbonization:
Equipment: The equipment is relatively simple, such as flame spraying, laser processing, etc.
Cost: Low, due to low energy consumption and time costs.
Summary
Deep carbonization: Applicable to materials that require overall performance improvement, with complex processes and high costs.
Surface carbonization: Applicable to materials that require surface performance improvement, with simple processes and low costs. If you have any equipment needs, please feel free to contact Zhengzhou Dingli New Energy Equipment Co., Ltd. The manufacturer will arrange professional engineers to select the appropriate carbonization method according to your specific needs to achieve the best results.
