Definitions

  • the present invention relates to an additive, to the use of said additive in paper or board production, to a method of improving paper or board manufacturing and to a method of improving paper or board product according to what is stated in the preambles of appending independent claims.
  • Pulp suspensions used in paper or board production contain besides cellulose fibers different kinds of extractives, that is a heterogeneous group of lipophilic and/or hydrophilic substances.
  • Particularly pulp suspensions including mechanical pulp may have considerable amounts of lipophilic substances, such as fatty acids, glycerides, sterol esters, sterols and resin acids.
  • an addition of high amounts of broke may increase the amount of lipophilic substances in pulp suspensions.
  • the lipophilic substances are by nature hydrophobic and form insoluble tacky aggregates, called pitch, which easily, particularly at certain temperatures, cause deposits on various surfaces of the paper or board machines.
  • the tacky aggregates typically adhere to cylinders, rolls and fabrics in the drying section of the paper or board machines, but may cause troubles elsewhere in the paper or board machines, as well, e.g. by depositing on felts and rolls in the press section. The troubles may lead to runnability problems, web breaks and the need to thoroughly clean the machine.
  • the insoluble aggregates may further cause quality problems such as holes and spots in the paper or board product.
  • paper or board products may be impaired by inexplicable unpleasant odors.
  • the surface sizing component used e.g. starch, has often been blamed for the odor.
  • degradation products from wood originating fatty acids have been found problematic in this sense. No single simple answer to the odor problem has been found. Odor problems tend to arise more often at some paper machines than at other.
  • a typical additive according to the present invention includes at least
  • fatty acid glycerides typically triglycerides, having a high percentage of unsaturated, particularly polyunsaturated, fatty acids.
  • the unsaturated fatty acids in the component may form cross-links between glycerides present in the added component, as well as, glycerides already present in the pulp suspension, whereby polymerization, so called drying, of the glycerides will take place.
  • the unsaturated fatty acids in the glycerides are believed to react with air oxygen, particularly at higher temperatures, to form the cross-links between glycerides. Saturated fatty acids or resin acids are not believed to form cross-links in a similar manner, whereby similar polymerization is not believed to take place.
  • the new additive comprising glycerides, preferably triglycerides, with a high content of unsaturated, particularly polyunsaturated, fatty acids.
  • the additive makes it possible e.g. to influence the formation and behavior of tacky aggregates in the pulp suspension and paper or board web, to influence the formation of unpleasant odors in the paper or board product and/or to influence the hydrophobicity of the final paper or board product.
  • the additive including a high percentage of unsaturated or polyunsaturated fatty acids, may be added to the pulp suspension or onto the paper or board web, e.g. by internal or surface sizing.
  • the additive may be added to the pulp suspension by internal sizing before the head box, in the head box or at any other suitable location.
  • the additive may, on the other hand, be added onto the wet or dry web in conjunction with surface sizing or coating.
  • a component for decreasing pitch problems, unpleasant odors or increasing hydrophobicity may thereby according to the present invention include
  • a component according to the present invention may e.g. be a raw or partly polymerized plant oil, such as sunflower oil, including high amounts of linoleic (C18:2) acid, and/or linseed oil, including high amounts of linolenic (C18:3) acid.
  • An additive according to the present invention may include in addition to the said component
  • emulsion stabilizers such as natural or synthetic polymers or inorganic particles, e.g. starches, starch derivatives, CMC, mannans, polyacrylamides, polyamines, bentonites, silicas,
  • one or more surfactants and/or - at least one conventional sizing component such as a synthetic sizing agent.
  • cationic emulsion stabilizers may be used.
  • cationic starch derivatives such as
  • Synthetic sizing agents such as AKD, ASA, styrene acrylate, styrene maleic anhydride or styrene acrylic acid copolymers, may be used.
  • Pulp suspensions in the papermaking or boardmaking process normally contain certain amounts of resin acids and fatty acids, the latter as free acids or esterifled as glycerides or sterol esters.
  • the resin and fatty acids normally present in pulp suspensions may be divided in two groups:
  • - drying acids i.e. unsaturated fatty acids, such as pinolenic or linolenic acid (C18:3), linoleic acid ( C18.2) and oleic acid (C18:l), and
  • non-drying acids such as resin acids and saturated fatty acids, such as stearic acid (C18:0), ante-iso-heptadecanoic acid (C17:0ai) and palmitic acid (C16:0).
  • drying acids i.e. unsaturated fatty acids
  • non-drying acids i.e. resin acids and saturated fatty acids
  • decomposition of some non-drying fatty acids in the pulp suspension or in the paper or board web may form components, such as heptaldehyde or hexaldehyde, causing a very unpleasant odor.
  • polymerization of fatty acids and/or glycerides in the pulp suspension or in the paper or board web according to the present invention may prevent such odor causing decomposition to take place.
  • Example 1 results of measurements made on a paper machine show that polymerization of glycerides in the pulp suspension coincides with less tacky agglomerates in the paper machine, i.e. with less pitch problems.
  • the example shows that polymerization of glycerides is favored by a high relative concentration of drying acids, i.e. unsaturated fatty acids.
  • samples IIB the measured relative concentrations of unsaturated fatty acids are significantly lower than in samples IIA. This indicates a polymerization or drying of glycerides, rendering the unsaturated fatty acids not measurable by the analysis method used.
  • Samples IIA were taken when the resin acid concentration, i.e. the concentration of a non-drying component, in the pulp suspension was high, generally above 0.6 kg/t (measured in ready paper) and samples IIB were taken when the resin acid concentration was low, generally below 0.6 kg/t (measured in ready paper) . Polymerization of glycerides was seen to take place in this particular pulp suspension as long as the resin acid concentration remained below about 0.6 kg/t. As the resin acid concentration increased the speed of polymerization decreased.
  • the resin acid concentration i.e. the concentration of a non-drying component
  • Example 2 The same analysis method as in Example 1 was used to determine the concentration of free fatty acids and fatty acids in non-polymerized glycerides in linseed oil and linseed oil varnish.
  • the latter (from this on named varnish) is partly polymerized linseed oil.
  • the degree of polymerization is about 10 % in varnish.
  • Unsized paper was produced from a standard furnish containing 30 % softwood and 70 % hardwood cellulose.
  • varnish has much better hydrophobic sizing performance compared with linseed oil at the same conditions.
  • Cationic starch with DS 0.2 was used as stabilizer with ratio to sizing agent of 2:1.
  • the sizing evaluation was carried out using laboratory handsheet former. A standard furnish (30 % softwood and 70 % hardwood) was used at different addition levels of the sizing agent. Percol 63 was added 300 g/t as retention aid. Alum was used with ratio 2:1 to sizing agent.
  • the sizing was poor with natural curing as the Cobb values were more than 60 g/m 2 at addition level of as high as 30 kg/t. However, with 3 day heating in an oven at 105 °C, a 3 kg/t addition level gave a good sizing result (Cobb 20.4 g/m 2 ).
