The Stickies Removal by Steam Explosion from Recovered Paper
The object of this work is to evaluate the optimal process of stickies removal on steam-explosion pulping from recovered paper. OCC (Old Corrugated Container), offset paper and coated art paper are presented for steam-explosion treatment. The parameters tested by single-factor tests are: liquor, explosion pressure, heat preservation time, and the charge of sodium hydrate and sodium silicate. The criterion used to characterize the stickies removal efficiency is the consistence of macrostickies and DCS in pulp after treatment. The compositional analysis are achieved the optimal explosion conditions. The use of steam explosion would be desirable in dealing with recovered paper.
