Description:

Please be noted:We can make sodium sulfide 93-95% with 300-500ppm chloride.

Sodium sulfide anhydrous is a deinking aid with good performance. 

Its role in deinking is to prevent the pulp from turning yellow. 

Sodium sulfide anhydrous deinking under weak alkaline conditions is more beneficial for ink removal.

In the absence of surfactants, it is disintegrated at 10% slurry concentration, and the addition of 2% sodium sulfite has obvious effects. 

Use neutral sodium sulfite for deinking old newspapers. 

The amount of sodium sulfite is 3% to 4%, which can obtain a good deinking effect, reduce the load of wastewater pollution, and facilitate the post-treatment of wastewater.
