This test method gives an indication of the oxidation resistance of raw natural rubber at a specified temperature. This resistance is indicated by the Plasticity Retention Index (PRI), a ratio expressed as a percentage of the aged plasticity to the original plasticity determined by means of a parallel plate plasto meter. A low PRI value indicates a poor resistance to oxidation.

Training Experience
Layout preparation
Dust plant condition estimation survey
Pitot tube U tube manometer preparation
Standardization of trunion rollers and fittings
8. 07
Layout preparation
Problem
Lack of space to move among machineries in pellet making plant.
Solution
New layout of machineries were suggested
Benefit to the company
Operator effort can be reduced.
Pleasant working environment with more useful space.
Maintenance easiness of the system.
Simplicity of the system.
Increased capacity of the production than before
Easy handling of the equipment due to more space.
10. 6:12 PM 09
Dust plant condition estimation survey
Problem
To identify the continuous pressure drop of the main pressure reservoir of the
firm
Solution
Remove all the diaphragms and springs of all the dust plants in the firm and
record
Benefit to the company
A new numbering criteria was introduced for the dust plants
Final report can be used as a reference to order spare parts for the dust
plants
Provided an overall feedback about condition of the dust plants
12. 11
Pitot tube U tube manometer preparation
Problem
Difficulty in identifying the leakages of compressed air
Solution
Prepare a U tube manometer as an air flow meter to attach to the main line
Benefit to the company
Easiness to identify compressed air leaks.
Reduce the leakages of compressed air
Increase the life time of the compressors
Reduce the maintenance labor hours
Support to the continuous production
14. 13
Standardization of trunion rollers and fittings
Problem
Difficulty in identifying the existing trunion roller types and their fittings and
handling of the inventory.
Solution
Standardize the trunion rollers and their fittings
Benefit to the company
The maintenance process becomes easier
The cost requirement for different types of rollers and fittings can be
reduced
Inventory handling becomes easier
The lifetime of the rollers and fittings can be increased due to equal force
distribution
The noise and the heat generation also can be reduced
16. Maintenance procedure of the firm need to be updated
Safety risk of the workers should be reduced
The company need to have more skilled employees
