Abstract
|
Accelerated aging test method was developed using a lab scale stainless steel reactor. Temperature, air pressure and composition were varied with constant time to analyze the effect on service life and activation energy of polyurethane (PU) foam samples obtained from industrial district heating (DH) pipe system. these accelerated aged PU samples were then analyzed using thermogravimetric analysis (TGA). The data obtained from TGA machine were used for calculation of activation energy (Ea) using Arrhenius equation. From that equation, activation energy (Ea) and service life were predicted using modified Chang method. Multiple temperature range (150 °C to 190 °C) and air pressure and composition were used to analyze and to predict the service life of PU of DH pipe system. As the given temperature in reactor is increased the aging of PU samples also increased, and service life decreased. In this research article accelerated aging method is developed using a small-scale tube reactor in which aging of industrial polyurethane (PU) foam samples was done using variable temperature, air pressure and composition.
