  • What is the role of Dispersion Science in pulp and papermaking process?
  • The role of dispersion science in pulp and papermaking process was reviewed by Rojas and Hubbe (2005). They explored the scientific principles that underlie the art of papermaking, emphasizing the state of dispersion of the fibrous slurries during various stages of the paper manufacturing process.
  • What is the dispersion of papermaking grade fillers?
  • The understanding of the dispersion of papermaking grade fillers is as important as their effect on paper. Magnesium silicate (talc) is one of the major fillers used for papermaking. It is hydrophobic and chemically inert.
  • How do wet and dispersing agents affect pigment dispersion time?
  • The use of suitable wetting and dispersing agents increases the speed of pigment surface wetting and for this reason can reduce the dispersion time significantly. On the other hand, wetting and dispersing agents reduce the interactions between the pigment particles and lower the viscosity of the mill base.
  • What is a dispersing agent?
  • Dispersing agents are an essential component in all pigmented layers starting with the ED-coating, followed by the primer and primer surfacer and the basecoat. Only the clear coat is (typically) without any dispersing agent.
