EXERCISE 16 : Demonstration on the concept of

conservation of raw material

Objectives

At the end of this exercise, you will be able to
• understanding conservation principles
• promoting sustainability awareness
• illustrating physical changes.

Procedure

Practical steps for conserving raw materials like mild steel flats using preventive measures and maintenance
techniques
Materials needed for conserving of raw materials
1 Raw materials like Mild steel flat (can be a small piece or sample)
2 Protective coatings (such as paint, primer, or anti-corrosion spray)
3 Cleaning materials (degreaser, wire brush, sandpaper)
4 Rust converter or inhibitor.
5 Lubricants (such as WD-40 or grease)
6 Protective equipment (gloves, safety glasses)
Demonstration Steps
1 Assessment: Begin by examining the raw materials for any signs of corrosion, rust, or damage. Note the
current condition to determine the appropriate conservation measures needed.
2 Cleaning: Use a degreaser and wire brush to remove any dirt, grease, or loose rust from the surface of the
mild steel flat. Ensure the surface is clean and free from contaminants that may interfere with subsequent
conservation steps.
3 Rust Removal: If there are areas of significant rust or corrosion, use sandpaper or a wire brush to gently
remove the rust until you reach bare metal. Be careful not to damage the surface of the mild steel flat during
this process.
4 Application of Protective Coatings
• Apply a primer specifically designed for metal surfaces to enhance adhesion and corrosion resistance.
• Once the primer has dried, apply a layer of protective paint suitable for mild steel. Choose a paint that
offers good adhesion, durability, and resistance to environmental factors.
• Alternatively, use an anti-corrosion spray or coating designed to protect metal surfaces from rust and
corrosion. Follow the manufacturer’s instructions for application.
5 Rust Conversion: If there are areas where complete rust removal is not feasible, apply a rust converter or
inhibitor to convert the rust into a stable compound. This helps prevent further corrosion and stabilizes the
affected areas.
6 Regular Maintenance
• Implement a maintenance schedule to inspect the raw material regularly for signs of corrosion, damage, or
wear.
• Clean the surface periodically to remove dirt, debris, and contaminants that can promote corrosion.
• Apply lubricants to moving parts or areas prone to friction to prevent corrosion and ensure smooth operation.
7 Protection from Environmental Factors: Store or install the mild steel flat in a location protected from
exposure to moisture, humidity, and corrosive chemicals whenever possible. Consider using protective covers
or enclosures to shield the steel from harsh environmental conditions.
8 Documentation: Keep records of the conservation activities performed, including dates of inspections,
maintenance procedures, and any repairs or treatments applied. This documentation helps track the
effectiveness of conservation efforts over time and informs future maintenance decisions.
