| Summary: | The diffusion behaviour of water and HCI solution at different temperatures and
concentrations into a modified polyethylene filled with carbon black used for lining ii presented. It
has shown the predominant role of nature of environment and carbon black content. In the both
environments, an increase of environmental temperature increased the capacity of environmental
absorption and the diffusion rate. The lower sorption capacity was observed at 40 and 60 oC while
a higher at 80oC in the water. The two-stage diffusion appeared for the case of the corrosive
environment.at 80oC. An increase of carbon black loading was increased both diffusion rate and
saturation values.
Diffusion of the environment into the polymer proposed by the following: environmental
molecules diffusing into the polymer matrix through porous syster& were trapped by functional
groups on the carbon black surface and polymer molecule chain, and are lmmobilized. This
explains the increase of sorption capacity when increase carbon black loading. |
