Gypsum plasterboard

The addition of lignin to a plaster suspension for natural and REA plasters significantly liquifies the slurries.

This means that, given an equal ratio of water to solids, the viscosity of the slurry is significantly lower when the dispersant magnesium lignin is added. The slurry can therefore be more easily processed by the production equipment.

 

Le lignosulfonate est un dérivé de la lignine très soluble et un produit issu du procédé de fabrication au bisulfite.

Our lignin is used in a variety of industrial and agricultural areas for various applications.
