Timber is preserved using specific chemical treatments applied through pressure or vacuum methods.
Preserving timber is crucial for extending its lifespan and protecting it from decay and insects. According to available information, the methods used vary depending on the intended application of the wood.
For timber designated for domestic purposes, specific techniques are employed involving chemical treatments:
- Pressure Treatment: This method utilizes water-borne chemicals. The timber is placed in a chamber, and pressure is applied to force the chemicals deep into the wood fibers, providing long-lasting protection.
- Double Vacuum Method: This technique uses organic solvent preservatives. It involves cycles of vacuum and pressure to ensure the preservative penetrates the timber effectively.
Here's a summary of these methods for domestic use:
| Method | Chemicals Used |
|---|---|
| Pressure Treatment | Water-borne chemicals |
| Double Vacuum | Organic solvent preservatives |
Applications of Preserved Timber
Beyond domestic use, timber treated with specific preservatives is utilized in more demanding environments requiring enhanced durability. Wood treated with both creosote and water-borne preservatives is commonly used in heavy-duty applications. Examples include:
- Transmission poles
- Warehouses
- Industrial buildings
- Agricultural buildings
These treatments provide the necessary resistance to harsh conditions and biological threats in these environments.
By employing these methods and chemical treatments, timber's longevity and performance are significantly improved for various applications.
