Topic: Processing of Materials – Wood (contd.)
Outline:
— Conversion
— Seasoning
Conversion
Wood is obtained from trees that grow all around us. However, wood cannot be used to produce the materials needed domestically and industrially, if the wood does not pass through the necessary stages of being processed.
Wood conversion is the process of splitting the log at sawmill with sawing machines into commercial and/or marketable sizes. The two popular methods of conversion are: ‘plain sawn’ and ‘quarter sawn’.
Seasoning
Freshly cut wood contains a lot of water or moisture, which makes it heavy. Seasoning is the process of reducing the water (moisture) in the wood. The reasons for seasoning or drying wood are:
- It makes wood more stable
- It makes wood lighter in weight and therefore easier to transport
- It generally makes wood stronger
Assessment
- State five reasons for seasoning wood
