Advantages:

1. Lightweight and durable, providing sufficient strength and durability.
2. Unique and uniform wheel grain texture.
3. Naturally resistant to corrosion.

Preservation Techniques:

1. Special Treatment: Introduce preservatives into the wood through chemical processes.
2. Coating: Apply a specialized coating on the surface for waterproofing, anti-corrosion, and anti-mold properties.

Extending Lifespan:

1. Regular Cleaning: Use mild cleansers and a damp cloth for periodic surface wiping, ensuring the removal of dust and dirt. Avoid excessive water usage to prevent wood swelling or deformation.

2. Avoid Direct Sunlight Exposure: Prolonged exposure to direct sunlight may lead to wood discoloration and surface damage. Try to minimize exposing the all-birch plywood to intense sunlight.

3. Adequate Ventilation: Maintain proper ventilation in the storage or usage space, helping to prevent moisture accumulation and reduce the likelihood of wood absorption.
