Discover the Science Behind Thermo Bamboo
Revolutionizing Bamboo into High-Performance, Sustainable Materials
What is Thermo Bamboo?
Bamboo is a fast-growing and renewable resource. However, in its natural state, bamboo is prone to decay, deformation, and pest damage.
At ZHUART, we transform raw bamboo into Thermo Bamboo through a process of high-temperature thermal modification and high-density compression. This technology strengthens the bamboo’s molecular structure, creating a material that is:
Sustainable: Eco-friendly and renewable, with minimal environmental impact.
Durable: Resistant to rot, pests, and deformation, even in harsh conditions.
Dimensionally Stable: Performs exceptionally well in fluctuating climates and moisture.
The material is high-density thermo bamboo—a strong, elegant, and sustainable material suitable for interior and exterior applications.
The Thermo Bamboo Process
1. Raw Material Selection
We carefully select mature 4-6-year-old moso bamboo from the renowned bamboo regions of Fujian and Zhejiang—areas celebrated for their abundant, high-quality bamboo. Moso bamboo at this stage provides the ideal balance of strength, density, and flexibility, laying the foundation for a high-performance product.
2. Splitting & Rolling
The harvested bamboo stems undergo preparation to ensure consistency and quality:
Splitting: Bamboo is split into uniform strips, and outer skins and nodes are removed.
Inspection: Each strip is thoroughly sorted and inspected, ensuring only defect-free material progresses to the next stage.
3. Thermal Modification
Bamboo strands are thermally treated in a controlled, oxygen-limited environment, enhancing their resistance to decay, pests, and moisture. This stage includes two critical phases:
Carbonizing: The bamboo strands are heated to temperatures up to 200°C with steam to protect against charring. This process breaks down water-absorbing molecular chains, eliminates sugars that attract fungi and pests, and enhances the bamboo’s durability while transforming its color into a rich, deep brown.
Re-Drying: To achieve optimal moisture content and to increase dimensional stability, the treated strands are carefully cooled, dipped in glue, and then re-dried.
This non-toxic process strengthens bamboo without chemical preservatives, reducing swelling, shrinking, and warping during future use.
4. High-Density Compression
The modified bamboo strands are compressed under extreme pressure to form a solid, dense material. This process achieves:
Density of up to 1150 kg/m³, surpassing tropical hardwoods.
Exceptional Hardness: Bamboo becomes stronger and more resistant to wear.
Enhanced Stability: Compression reduces internal stresses, ensuring the material maintains its shape in extreme weather.
The result is a highly durable and dimensionally stable material suitable for outdoor environments.
The 5,400-ton press is currently the largest press is the industry. It can press up to 4.2 metres in length and 60mm thick.
5. Shaping & Finishing
The compressed bamboo material is precision-engineered into its final form to meet diverse project requirements:
Cutting and Profiling: Boards are shaped into decking, cladding, or panels, ensuring perfect fit and easy installation.
Surface Treatment: Finished with eco-friendly oils, the bamboo gains enhanced protection against moisture, UV rays, and environmental wear.
Quality Control: Each board is inspected for consistent color, smooth surfaces, and structural integrity, adhering to ZHUART’s strict quality standards.
Key Benefits of Thermo Bamboo
Thermo Bamboo offers unmatched durability, dimensional stability, and sustainability compared to untreated bamboo and traditional hardwoods.
Benefits at a Glance:
Superior Durability: The highest resistance class to corrosion, fungi, and termites.
High Density: Stronger than most tropical hardwoods, perfect for heavy-duty use.
Dimensional Stability: Significantly reduce warping, shrinking, and swelling in extreme climates.
Eco-Friendly & Healthy: Non-toxic process with minimal harmful chemicals.
Aesthetic Appeal: Deep, rich brown tones and smooth textures enhance architectural designs.
ZHUART Thermo Bamboo has significantly higher density and greater resistance to bending under load than most of natural wood.
