- Non-Wood Materials In WoodWork Projects
Non-wood materials used in woodwork include the following:
- Adhesive (gum and glue).
- Abrasive (sandpaper).
- Hinges and locks.
- Nails, screws, and fittings.
1. Adhesive:
These are substances that can bond wooden, leather, and other non-wood materials together. There are three groups of adhesives as shown below.
a. Protein Adhesives: These are natural adhesives derived from various protein sources. They include scotch glue (animal glue), casein glue made from milk, and blood albumen glue (animal blood).
b. Synthetic Adhesives: These are adhesives made from organic compounds. They include thermoplastic glue (adhesives that can melt under heat) and thermoset glues (glues that cannot melt under heat).
c. Contact Adhesives: These are the type of adhesives used for dissimilar materials. Examples of dissimilar materials are wood and leather, paper and leather, or plastic and metal. The types of adhesives in this group include Evo-Stik, Bostick, super-glue, Araldite, etc.
2. Abrasives:
These are papers, cloths, and fibres that are coated with hard minerals like sand, that are used to smoothen the surface of other materials like rough surfaces of wood, rusted metals, etc. They are grouped as either coarse (rough) type, medium, and fine (smooth) type.
Sanding is mechanical surface treatment with abrasives.
3. Hinges:
