How does the EDS technique alter the wood’s composition? |
- How does the EDS technique alter the wood’s composition?
- When heat is applied to raw materials within the sealed plant, the moisture vaporizes. Components such as hemicellulose and lignin break down and the wood’s molecular weight decreases.
- When the temperature within the plant is gradually decreased, the components blend and harden. At the end of process, the quality of the raw material (the wood) is dramatically enhanced.

*Glossary
●Cellulose: |
Comprises around 50% of the wood. A relatively stable
substance made of straight chains of glucose. |
●Hemicellulose: |
Comprises approximately 20〜30% of the wood. A different
type of sugar than cellulose. Because its binding structure is not as orderly as
that of cellulose, the substance breaks down easily by hydrolysis. |
●Lignin: |
Comprises approximately 20〜30% of the wood. This macromolecule
is irregular in form and includes benzene rings.
