- Abstract
The laboratory simulated whitewater of newspaper was studied to reveal the instability mechanism of microstickies, by changing the stirring speed and real-time monitoring various physical and chemical indexes, such as the number of microstickies, the turbidity, conductivity, Zeta potential.etc.The resultsof experiment shown that the stability of microstickieswas clearly related to stirring speed. The stirring speed lower than 300 r/min, colloidal substances (CS) and microstickies were aggregated due to they could not be effectively dispersed, the total number of microstickies was decreased from 5.1509×106 pcs/mL to 4.8491×106 pcs/mL. With the increase of the stirring speed (in 350 r/min,400 r/min), a part of the unstable bound microstickieswere dispersed into the smaller pellet, the total volume increasedfrom 0.64492 mm3/mL to 0.7321 mm3/mL, when stirring speed was higher than 400r/min, the dispersing and coagulation increased at the same time. But more than 700 rpm, many stickies were dispersed, the total number of microstickies increased from 5.7626×106pcs/mL to 6.3115×106pcs/mL.
