Hydrogenation of Spinning Solutions in the Spinning of Aramid Fibers

详细

The formation of hydrogen bubbles resulting from electrochemical reactions between the solution for the spinning of aramid fibers and the with metals of the pump casing and gears produced in Ukraine was studied. This effect, which the author calls “hydrogenation of spinning solutions,” shortens the pump life and greatly reduces the quality of the fibers. The possibility of increasing the life of the metering gear pump used for the production of aramid fibers by means of a new pump design with casing and gearing made from composite materials based on a polymeric matrix developed by the author was investigated.
