Apr 20, 2021 · The effect of reaction time and temperature on DS has been reported by G. Joshi et al. (2014) , while DS increased up to 50 °C (optimum temperature) and 3 h (optimum time) reaction time. The DS decreased beyond the optimum temperature and time due to improving oxidant atmosphere and oxidative degradation of CMC.

Performance testing of retention aid drainage. The retention efficiency needed to be measured using a dynamic water filter. The wet pulp with a dry fiber mass of 5 g was added to a fiber disintegrator. The ratio of the raw material pulp was LBKP:NBKP = 70:30. The solution was defibrized for 5 min and diluted with water.
