Modeling the Kinetics of Swelling of Offset Rubber Fabric Blend Based on EPDM in Contact with a Remover

Abstract

A model has been developed to predict the swelling kinetics of offset rubber-fabric blanket based on ethylene-propylene rubber (EPDM) reinforced with cotton fabric when in contact with acetone, kerosene, and mixtures of kerosene and acetone in various ratios. The method for determining the degree of blanket swelling involved immersing samples in kerosene, acetone, and their mixtures. The degree of blanket swelling was determined as the ratio of the mass of sorbed liquid for a certain holding time to the mass of the original sample.

The model is designed to predict the dependence of the degree of blanket swelling on the duration of contact of the blanket with kerosene, acetone, and their mixtures of variable composition. The model is an equation that describes the kinetic dependencies of blanket swelling in the coordinate of conventional time, which is calculated as the square root of the holding time of the blanket in the wash. The method used is standard and is intended for determining the parameters of diffusion transfer of liquids in polymeric materials. It was found that in the coordinate system of conventional time, the kinetic dependences of fabric swelling in acetone, kerosene and their mixtures differ from the standard dependences of polymeric materials swelling. The obtained kinetic dependences of rubber fabric swelling in the coordinate system of conventional time are described by equations with two empirical coefficients of dimension.
