What Will You Learn?

  • Understanding the various types and methods of rubber lining as rubber lining is a process driven activity which is labour intensive.
  • Material Selection: The selection of the right rubber compound is essential to ensure chemical resistance, temperature resistance, and overall performance in the specific application.
  • Visual Inspection: A thorough visual inspection of the rubber lining is necessary to detect any defects, such as blisters, bubbles, cracks, or uneven application.
  • Thickness Measurement: Regular measurement of the rubber lining thickness helps ensure that it meets the required specifications and provides adequate protection.
  • Shore A hardness and vulcanisation of rubber linings.
  • Adhesion Testing: Adhesion testing involves checking the strength of the bond between the rubber lining and the substrate. Common methods include pull-off tests and adhesion tape tests.
  • Follow industry standards and best practices for rubber lining application.
  • Continuity testing of rubber linings.
