Fixation of reinforcing fabric for ion exchange membrane

Popis výsledku v původním jazyce

A reinforcing fabric is an integral part of heterogeneous ion exchange membranes (IEMs). It guarantees the mechanical resistance of IEMs. Thermal fixation of the fabric is one of the most important refining operations, which is also reflected in the production of IEMs during lamination on heated cylinders. The influence of the fixation temperature (grey variant, 120, 160 and 215 °C) of the Ulester 31HDA polyester fabric with a twill weave on the production of IEMs was studied. DSC, iodine sorption value measurement, or dimensional stability during the additional heat load were studied for commercially supplied fabrics Ulester 31HDA. The values were compared with the model series of fabrics prepared in laboratory drying under precisely defined conditions (temperature and time). The principle of fixation is the rearrangement of the internal fiber structure associated with the change of the crystalline phase. The reinforcing fabric is dimensionally stable up to the fixation temperature. Iodine sorption value decreased with the increasing temperature of fixation. Any changes were not seen from SEM images or density measurements. DSC analysis did not show the predicted dependence for the model series of fabric. Dimensional changes after temperature loading increased with temperature.
