           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.
