Abstract
Sposób modyfikacji chemicznej diafragm z włókien technicznych (WT), polega na osadzeniu w porach tj. (przestrzeni międzywłóknowej) WT substancji chemicznej odpornej na restrykcyjne warunki fizyko-chemiczne panujące w strefie międzyelektrodowej elektrolizera. Wskutek osadzenia w porach diafragmy (przestrzeni międzywłóknowej) modyfikatora zostaje znacznie pomniejszona średnica porów przenoszących jony, a także, z uwagi na porowatą strukturę wprowadzonej substancji, wydatnie zwiększona ich ilość, długość oraz współczynnik krętości porów. Efektem ww. działań jest znaczna poprawa właściwości separacyjnych diafragm z WT w rozdziale różnoimiennych komór elektrodowych, a w konsekwencji znaczne ograniczenie niekorzystnej dla procesu elektrolizy wymiany masy związanej z dyfuzją i migracją jonów OH- z komory katodowej do anodowej.The method of chemical modification of diaphragms made of technical fibers (WT) consists in embedding in the pores, i.e. (interfiber space) of WT, a chemical substance resistant to the restrictive physical and chemical conditions prevailing in the inter-electrode zone of the electrolyser. As a result of embedding the modifier in the pores of the diaphragm (interfiber space), the diameter of the pores carrying ions is significantly reduced, and, due to the porous structure of the introduced substance, their number, length and coefficient of pore tortuosity are significantly increased. The effect of the above The aim of these actions is to significantly improve the separation properties of WT diaphragms in the separation of dissimilar electrode chambers, and as a consequence, to significantly reduce the mass exchange associated with the diffusion and migration of OH- ions from the cathode to the anode chamber, which is unfavorable for the electrolysis process.
