Definitions
- the minimum pressure required during the dripping is, depending on the steam pressure of the water contained in the polyamide melt, depending on the temperature traveled. In practice, it should not be below 3 bar. It should also be no more than 2 bar lower than the pressure under which the hydrolytic polymerization is carried out. However, in order to be on the safe side, one will choose a higher than the minimum required pressure and, if necessary, set it even higher than the pressure under which the hydrolytic polymerization is carried out.
