Definitions
- the invention relates to the use of agents for the treatment of machines for the manufacture of pulp, paper and cardboard for cleaning these aggregates from adhering contaminants made of natural resins and / or synthetic polymers, and to preventing the contamination of these aggregates by such contaminants .
- inhibitory mixtures of surfactants and solvents preferably fatty acid alkanolamides, ethoxylated compounds, aliphatic hydrocarbons and orange terpenes, are added to the stock suspension in an amount of 1 to 200 ppm.
- solvents preferably fatty acid alkanolamides, ethoxylated compounds, aliphatic hydrocarbons and orange terpenes.
- the agents used in this way are only insufficiently effective, so that the manufacturing process often has to be interrupted in order to clean the machine parts, in particular the wire and press section, whereby according to EP 178 340 B1 only limonene is used as the solvent finds.
- EP 359 590 B1 therefore proposes an aqueous solution of cationic polymers together with a water-soluble, nonionic or cationic on the surface of the devices Apply surfactant.
- the disadvantages of this procedure are characterized in that the coating layer which forms is dependent on the equilibrium concentrations of the water-soluble components in the system and the brown-colored, elastic structure of the protective film becomes hard and brittle in the absence of moisture.
- a further disadvantage arises from the very specific metering of several components which is sometimes required in order to produce the coating.
- EP 0 648 820 A2 describes compositions which are used for removing toners from paper surfaces, adhesive residues from plastics, for removing plastic coatings and for cleaning metal surfaces from cutting oil residues or colored pencil markings, and for removing PVC parts attached by adhesives become.
- Concentrated oil-in-water emulsions with a non-aqueous phase content of 8-90% by weight are used, which contain a wide variety of organic compounds, as well as dicarboxylic acid diesters, and some with the use of ultrasound and other auxiliaries (unwoven fabric strips) in the temperature range from 5 to 70 ° C., that is to say partially with additional heating of the cleaning agent during the cleaning process.
- the emulsions also contain solvents such as isopropanol, toluene, benzyl alcohol, methyl ethyl ketone, N-methylpyrrolidone, di- and triethylene glycol dimethyl ether and 3-methyl-3-methoxybutanol, which limit the use of these emulsions in closed systems for reasons of occupational safety and health limit because of health risk.
- solvents such as isopropanol, toluene, benzyl alcohol, methyl ethyl ketone, N-methylpyrrolidone, di- and triethylene glycol dimethyl ether and 3-methyl-3-methoxybutanol
- the object was therefore to eliminate the disadvantages described in detail above and, in particular, to find means for this purpose whose use in pulp, paper and cardboard production with waste paper is suitable for the treatment of pulp, paper and board machines To clean machines from adhering agglomerates of synthetic polymers and natural resins and / or to prevent such substances from adhering to the surface of the machines.
- the task could be solved by the use of oil-in-water emulsions for the treatment, in particular for the cleaning of cellulose, paper, cardboard or cardboard machines or their plant parts of adhering synthetic polymers and natural resins or for preventing such substances from adhering the surfaces of such machines or plant parts can be solved.
- the emulsions mentioned are characterized in that they contain, as part of the oil phase, at least one of the following substances, alone or in a mixture with the other substances mentioned:
- a saturated or unsaturated fatty alcohol a saturated or unsaturated fatty acid, a fatty acid monoalkyl ester, a fatty acid amide or a fatty acid monoalkylamide of a saturated or unsaturated fatty acid, all of the compounds listed under 2 with 8 to 30 carbon atoms
- oil-in-water emulsions described are known from various fields. However, it was surprising to find that these emulsions have the property 1. to clean machines and plant parts from special contaminants and 2. to prevent such special contaminants from adhering to the surfaces of machine assemblies or plant parts.
- the preparation of the emulsions to be used according to the invention in particular stable oil-in-water emulsions, is known.
- the oil component is emulsified in water by means of suitable known oil-in-water emulsifiers.
- the hydrophobic phase predominantly represents the active ingredient.
- hydrophobic oil components The following are examples of hydrophobic oil components:
- - Fatty alcohols such as octanol, dodecanol, tridecanol, octadecanol, behenyl alcohol
- - fatty acid ester such as Stearylkladlemethylester, Palmitinkladreoctadecylester, ⁇ lklareoctylester, glycerol and trioleate, ethylene glycol dilaurate, sorbitan stearates and oleates and esters, in particular diesters of aliphatic and / or aromatic di- and / or tricarboxylic acids, such as C j - C 13 alkyl and isoalkyl esters of C 2 - C 12 dicarboxylic acids, such as oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, sebacic acid, ⁇ pp ⁇ rock acid, tartaric acid, citric acid, phthalic acid, dodecanoic acid, C 9 -dicarboxylic acid (trimethyladipic acid and fumaric acid) and maleic acid.
- esters are: Di-n-butyl oxalate, di-n-butylmalonate, di-n-butyl succinate, di-n-butyl glutarate, di-n-butyl adipate, di-n-butyl suberate, di-n-butyl sebacate, dimethyl adipate, diethyl adipate, di-n- propyl adipate, diisopropyl adipate, diisobutyl adipate, di-tert-butyl adipate, di-isoamyl adipate, di-n-hexyl adipate, di- (2-ethylbutyl) adipate, di- (2-ethylhexyl) adipate, diisodecyl adipate, dimethylphthalate, die- Di-n-butyl phthalate, diisobutyl phthalate, di (2-eth
- - Fatty acid amides such as stearylamide, coconut fatty acid butylamide, acetic acid oleylamide and ethylene bisstearylamide.
- hydrocarbons or hydrocarbon mixtures are paraffin oil, mineral oil or poly-alpha-olefins.
- agents to be used according to the invention are surprisingly suitable as cleaning agents or as agents with an impregnating action against impurities such as adhesives, resins, waxes, fats and / or bitumen-repellent effects 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 by treating the screens, felts in the wet area of the machines and the dry screens, 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 aggregates before they come into contact with the material web and, if appropriate, separately for the top and rear areas of the products.
- the oil-in-water emulsions are used as such or after dilution with water and / or solvents, preferably water-miscible solvents.
- water is used for this purpose, which has temperatures in the range from 5 to 80 ° C., preferably from 20 to 50 ° C.
- 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, based on the aqueous dilution.
- the diluted emulsion is applied in a quantity of 20-500 l, preferably 100-400 l per hour and meter working width of the machine in continuous or intermittent dosing, the diluted emulsion in any manner, preferably via a spray tube provided with flat jet nozzles with an overlapping spray area is abandoned.
- the emulsion can also be added to the washing water in dry sieve cleaning systems.
- oil-in-water emulsions preferably used according to the invention contain biodegradable components and are therefore environmentally compatible.
- the diluted emulsion When used, especially with heavily soiled dryer fabrics, the diluted emulsion is applied in the return of the dryer fabric and, if necessary, the screen is inflated with air before it hits the paper web.
- sticky impurities lose their adhesive action and dissolve independently or when sprayed with water from the surface of the aggregates and are removed.
- the cleaning action of the agents in the sieving and drying section of the machines continues until the last machine part.
- the impregnating, inhibiting effect against renewed contamination on the aggregate surfaces is product-related and type-dependent and lasts for a period of 4-75 hours after the end of the metering.
- the aggregates can be cleaned and impregnated each time the grade is changed.
- Emulsion Oil Pase Water Amount Amount Amount (% by weight) (% by weight) (% by weight) (% by weight)
- L bone fat PO (1) 14.0 fatty alcohol Ci 2 - ⁇ + 10 EO 8.4 77.6
- a 20% by weight aqueous dilution of the emulsion M in an amount of 250 l per hour and per meter working width of the endless screen is applied to the paper-contacting side of the drying screen before the screen touches the paper web by means of flat spray nozzles of a spray tube at a distance of 25 cm, arranged with the spray fields overlapping, are applied with intermittent dosing in a time of approximately 10 minutes.
- the impurities are loosened from the sieve and the subsequent guide rollers and cylinders and partly removed by throwing out the agglomerates, especially in the initial phase of the treatment.
- the cleaning effect can also be determined on the following machine parts and lasts up to the smoothing cylinder. After the metering of the diluted emulsion has ended, an inhibiting effect against adhering contaminants is observed, which lasts for about 24 hours.
- Emulsion B is applied to a dirty plastic screen of a paper machine, consisting of polyamide and polyester fibers.
- FIG. 1 shows four samples of the sieve, starting from the heavily soiled first sample (O sample). With sample 2 after 6 hours at room temperature, with sample 3 after 30 minutes at 60 ° and with sample 4 after 60 minutes at 60 °, the cleaning effects are very clearly recognizable. The air permeability of the sieve was measured. It increases from 320 cfm to 530 cfm in sample 4.
- Example 4 Analogous to the procedure in Example 1, the emulsion M was applied to the dryer fabric during the production process in an aqueous dilution of 1: 6 parts by weight in a daily amount of 30 l in 6 uniform time intervals. The contaminated sieve was cleaned.
- Example 4 Analogous to the procedure in Example 1, the emulsion M was applied to the dryer fabric during the production process in an aqueous dilution of 1: 6 parts by weight in a daily amount of 30 l in 6 uniform time intervals. The contaminated sieve was cleaned.
