Board paper / packaging paper

Board paper and packaging paper

During the production of paper and cardboard for packaging, odor nuisances are increasingly arising in the vicinity of the paper mill. The reasons for this are bacterial reactions in the production process, which generate organic acids, among other things. LEVACO PAPER SOLUTIONS offers optimized products for odor neutralization as well as for other challenges such as foaming, water hardness regulation, retention as well as cleaning of paper machines.



Process auxiliaries

DEFOKALK® 450 FD

  • Highly efficient product based on calcium hydroxide in suspension form for complete sanitation of the water cycle
  • Regulates pH and reduces water hardness and organic acids in a fast reaction time
  • Strengths of the paper are increased and the effectiveness of other auxiliaries used is improved
  • Appearance: milky-white suspension / active ingredient (%): 45

Defoamer

DEFOSPUM® PWW 90

  • Emulsion of fatty alcohols, without silicone and mineral oil components for application on the paper machine and in wastewater treatment plants
  • Very effective in a wide pH and temperature range
  • Biodegradable and approved according to FDA and BGA XXXVI recommendation
  • Appearance: white emulsion / viscosity (mPas): 250

DEFOSPUM® PWW 74

  • Emulsion of fatty alcohols, without silicone and mineral oil components for application on the paper machine and in wastewater treatment plants
  • Very effective in a wide pH and temperature range
  • Biodegradable and approved according to FDA and BGA XXXVI recommendation
  • Appearance: colorless liquid / viscosity (mPas): 200-600

DEFOSPUM® PHT 110

  • Aqueous preparation of polyether polyols in combination with natural fatty acids
  • Excellent suitability as defoamer and deaerator for the entire water circuit in the paper industry
  • Excellent long-term effect without influencing the medium to be foamed in
  • Appearance: viscous liquid / viscosity (mPas): 100

Flocculants

DEFOFLOC® CL series

  • Cationic liquid flocculant based on an emulsion of a polyacrylamide
  • It is mainly used as a retention agent and dewatering accelerator on paper machines and in wastewater treatment plants
  • Appearance: viscous milky liquid / viscosity (cP): 500-2000

DEFOFLOC® CP series

  • Medium to high molecular weight polyelectrolyte based on a cationic acrylamide derivative
  • Especially suitable as retention agent and dewatering accelerator at the paper machine and at wastewater treatment plants
  • Appearance: white granules

Impurity fixer

DEFOFIX MCA 50

  • Highly cationic, cross-linked impurity fixing agent
  • Stands out as a highly effective primary flocculant and complies with the requirements of the XXXVI Recommendation of the BfR
  • Appearance: clear to slightly turbid liquid

Industrial cleaners

DEFOCLEAN® OT series

  • Special formulation of detergents and emulsifiers
  • Ideal as a cleaning agent and odor control agent in the entire machine circuit
  • Due to its hydrophobic character, it also removes existing dirt and adhesions
  • Appearance: thin, milky-white emulsion

DEFOCLEAN® 222 MOD 1

  • Special formulation of detergents and emulsifiers
  • Approved with water hazard class 1
  • Due to its hydrophobic character, it also removes existing dirt and adhesions
  • Appearance: viscous yellow liquid
