Abstract In CPB(Cold-Pad-Batch) dyeing, the rubber of the padder roll is influenced by
the heat, chemical and mechanical influences and thus aging of the padder roll rubber
occurs. This study presents an accelerated thermal aging test of the CPB padder roll rubber
with strong alkali conditions. Using Arrhenius formula of the various property values
for the various aging temperatures(80C, 90C, 100C) of the padder roll, the accelerated
life predictions could be calculated. The threshold value of the property was set at different
values. The hardness was set at the point where 5% degradation occurs based on the
actual use conditions, and the tensile strength was set at the point where 50% degradation
occurs based on the general life prediction standards. From the results of the different
physical properties at differing temperatures, the Arrhenius plot could be obtained.
Through the usage of the Arrhenius Equation, significant duration expectation could be
predicted, and the chemical aging behavior of the CPB padder roll could be found at the
arbitrary and actual temperatures. |
