Definitions
- Paper and paperboard are produced from an aqueous slurry of cellulosic fiber, depositing this slurry on a moving papermaking wire or fabric, and forming a sheet from the solid components of the slurry by draining the water. This sequence is followed by pressing and drying the sheet to further remove water.
- Drainage or dewatering of the fibrous slurry on the papermaking wire or fabric is often the limiting step in achieving faster paper machine speeds. Improved dewatering can also result in a drier sheet in the press and dryer sections, resulting in reduced energy consumption.
- Chemicals are often added to the fibrous slurry before it reaches the papermaking wire or fabric to improve drainage/dewatering and solids retention; these chemicals are called retention and/or drainage aids.
- Dry strength additives are used in paper mill to increase the strength of paper. It increases the strength of paper by increasing internal bond formation. Moreover dry strength additives improve bust strength, tear strength, wax pick values, folding endurance, stiffness, machine runnability, increase levels of paper filler uses etc. Dry strength additives also reduced linting and dusting.
- Retention and drainage aids have reduced efficacy in some furnish substrates which contain high levels of soluble organics and salts.
- Two such examples of these furnishes are neutral sulfite semi chemical (NSSC) and kraft virgin linerboard, where high levels of soluble lignin and other organic materials containing a high anionic charge are present. These highly anionic materials neutralize the charge on the conventional retention and drainage aids, significantly reducing their effectiveness.
- the PEO reacts with the excess lignin and other excess anionic materials in the cellulosic furnish thereby allowing the drainage or strength agent to work without be hindering by reacting with the undesirable materials.
- Molecular weights are viscosity average molecular weight as determined from intrinsic viscosity determinations.
- the PEO can be a homo-polymer of ethylene oxide, or a copolymer of ethylene oxide.
- Suitable comonomers include propylene oxide or butylene oxide.
- a homopolymer of polyethylene oxide is the most preferred.
- Additional suitable comonomers used to make the PEO copolymer can be cationic, anionic, non-ionic or hydrophobic monomers, and any mixture thereof.
- the molecular weight of the PEO homo-polymer or co-polymer can range from 1000 daltons up to 25,000,000 daltons or 100,000 to 15,000,000 daltons or 1,000,000 to 10,000,000 daltons.
