product features
enhancement effect is obvious, wet strength increase 5 to 10 times, dry strength increased 20-30%.positive charge density is high, it can increase the pulp drainability and papermaking speed, increase the retention rate of filler, glue and fine fiber. Do not contain "free aldehyde", at the same time avoid the paper yellowing after a long .the range of application is wide. The fiber can absorb it from acid to alkaline broad ph range, can achieve good wet strength effect without adding aluminium sulfate.
it will achieve a better effect in neutrl and weak alkaline conditions.
Dosage and methods
1.0.5�1.0% to oven dry stock, best use of ph value is 7.5-8.0
2.broken paper and waste paper recucling easy:unbleached paper: the ccondition of beating can be controled to the ph value to about 65c.
3. Bleaching paper: adjust ph value to 5-8, the temperature is about 5�. The effect will be better if add a small amount of sodium hypochlorite.
