Definitions

  • the invention relates to the use of agents for treating machines for pulp, Paper and cardboard manufacture for cleaning these aggregates from adhering impurities from natural resins and / or synthetic polymers as well as prevention the contamination of these units by such impurities.
  • EP 517 360 A1 inhibiting mixtures of surfactants and solvents, preferably fatty acid alkanolamides, ethoxylated compounds, aliphatic Hydrocarbons and orange terpenes of the stock in an amount of 1 - 200 ppm added.
  • solvents preferably fatty acid alkanolamides, ethoxylated compounds, aliphatic Hydrocarbons and orange terpenes of the stock in an amount of 1 - 200 ppm added.
  • the funds used in this way are insufficiently effective, so that the manufacturing process often has to be interrupted in order to clean the machine parts, in particular to make the wire and press section, whereby according to EP 178 340 B1 exclusively Limonene is used as a solvent.
  • dispersing agents are only in closed water cycles limited possible, since the dispersed resin parts do not fully adhere to the anionic cellulose fibers are bound and discharged so that they are increasingly in the process water remain.
  • the cleaning of the felts of the press section is also used proposed by fatty acid imidazolines and according to EP 647 737 A1 these compounds together with ethoxylated nonylphenols and special sulfonates for prevention of deposits of polyamidoamine-epichlorohydrin resins used in felts.
  • EP 0 648 820 A2 describes compositions which are used to remove toners from Paper surfaces, adhesive residues of plastics, for removing plastic coatings and for cleaning metal surfaces from cutting oil residues or colored pencil markings used, as well as used to remove PVC parts attached by adhesives become.
  • the emulsions also contain solvents such as isopropanol, Toluene, benzyl alcohol, methyl ethyl ketone, N-methyl pyrrolidone, di- and triethylene glycol dimethyl ether and 3-methyl-3-methoxybutanol, which are the use of these emulsions in closed systems for reasons of occupational safety and health risks restrict.
  • solvents such as isopropanol, Toluene, benzyl alcohol, methyl ethyl ketone, N-methyl pyrrolidone, di- and triethylene glycol dimethyl ether and 3-methyl-3-methoxybutanol, which are the use of these emulsions in closed systems for reasons of occupational safety and health risks restrict.
  • the object was therefore to eliminate the disadvantages described in detail above and in particular to find means for this, their use in the manufacture of pulp, paper and cardboard with waste paper for the treatment of pulp, paper and board machines is suitable., the machines of adhering agglomerates made of synthetic polymers and to clean natural resins and / or the adherence of such substances from the surface to prevent the machines.
  • the task could be accomplished by using oil-in-water emulsions for treatment, especially for cleaning pulp, paper, cardboard or cardboard machines respectively their parts of the plant from adhering synthetic polymers and natural Resins or to prevent such substances from adhering to the surfaces of such Machines or system parts can be solved.
  • Oil-in-water emulsions are known.
  • the oil component in water by means of suitable known oil-in-water emulsifiers.
  • the hydrophobic phase is predominant the active ingredient.
  • hydrocarbons or hydrocarbon mixtures are Paraffin oil, mineral oil or poly-alpha-olefins.
  • the agents to be used according to the invention are surprisingly used as cleaning agents or as an agent with an impregnating effect against impurities such as adhesives, resins, Wax, fat and / or bitumen repellent effect at any point on the pulp, paper and board machines.
  • the agents according to the invention are used on the surface of the aggregates, in particular treating the sieves, felts in the wet area of the machines and the drying sieves, Guide rollers and drying cylinders in the drying area.
  • the agents according to the invention are preferably used on the material-contacting surface of the units before they come into contact with the fabric and, if necessary, separately for the deck and Back area of the products.
  • the oil-in-water emulsions are used as such or after dilution Water and / or solvents, preferably water-miscible solvents.
  • Water is used for this purpose, the temperatures in the range from 5 to 80 ° C., preferably 20 - 50 ° C.
  • the concentration of the oil-in-water emulsion in aqueous dilution is 1-40% by weight, preferably 5-25% by weight and particularly preferably 10-25% by weight on the aqueous dilution.
  • the diluted emulsion is in an amount of 20 - 500 l, preferably 100 - 400 l per hour and meter working width of the machine in continuous or interval dosing applied, the diluted emulsion in any Way, preferably via a spray tube provided with flat jet nozzles with an overlapping one Spray area is abandoned.
  • the addition can also be added to dryer fabric cleaning systems the emulsion to the wash water.
  • oil-in-water emulsions preferably used according to the invention contain biologically degradable components and are therefore environmentally friendly.
  • the diluted one Emulsion applied in the return of the dryer fabric and, if necessary, the screen before hitting it inflated with air on the paper web.
  • the cleaning effect of the agents keeps when using the agents according to the invention in the Sieve and dryer section of the machines continuously up to the last machine part.
  • the impregnating inhibitory effect against renewed contamination on the aggregate surfaces is product and variety dependent and lasts after the end of the dosage over a period of 4 - 75 hours.
  • the aggregates can be cleaned and impregnated with every change of grade.
  • the contaminants are removed from the screen and the subsequent guide rollers and cylinders solved and partly with the agglomerates being thrown out, especially in the initial phase the treatment removed.
  • the cleaning effect is also on the following machine parts lockable and lasts up to the smoothing cylinder. After the dosage of the diluted Emulsion has an inhibiting effect against adhering contaminants, which lasts about 24 hours.
  • FIG. 1 shows four samples of the sieve, starting from the heavily soiled first sample (0 sample). In sample 2 after 6 Hours at room temperature, with sample 3 after 30 min at 60 ° and with sample 4 after 60 min at 60 ° the cleaning effects are very clearly recognizable. The air permeability of the Siebes was measured. It increases from 320 cfm to 530 cfm in sample 4.
  • the emulsion M was in an aqueous dilution of 1: 6 parts by weight in a daily amount of 30 l in 6 even time intervals applied to the dryer fabric during the production process.
  • the contaminated sieve has been cleaned.
  • the emulsion M On the felt of a paper machine, contaminated by adhesives and resins, consisting of Polyamide and polyester fibers, the emulsion M is diluted with a spray tube applied to 15% by weight with water.
  • the impurities adhering to the surface and in the felt detach, so that the water absorption of the felt with an improved effect takes place and the surface of the paper webs are formed evenly and without false marks becomes.
