Utilization of StarLig in plasterboard production can lead to substantial energy savings and better quality of board produced at a higher production rate. This applies to both natural and synthetic gypsum raw materials.
The product acts as a dispersing agent and water reducer in plaster mixes. They act on the solid plaster particles breaking down their normal agglomeration due to Van der Waals forces of attraction. This gives a much finer divided state than normal, giving the finer particles a slightly negative charge. Each particle can then move freely against each other due to slight repulsive forces acting on each particle, without affecting the normal hydration process.
The result of this dispersion is that the plaster slurry is much more free-flowing than normal. It is from this effect that a large part of the advantages, of utilizing StarLig, in plaster production is obtained.
