Definitions
- the raw material i.e. H. Cellulose
- fillers which give printing and writing papers in particular an even formation, better softness, whiteness and grip.
- These fillers which are usually called “ash”, since they remain as ash in the combustion analysis, are either added to the fiber suspension or applied during brushing.
- Natural printing papers contain up to 35% by weight of fillers, coated papers 25% to 50% by weight. The amount of filler depends very much on the intended use of the paper. Heavily weighted papers have lower strengths and poorer sizing.
- Coating pigments that can come from residual coating colors or coated scrap.
- the grain size plays an important role, since it strongly influences the filler yield and the physical properties of the paper, especially the porosity.
- the filler content remaining in the paper is between 20 and 80% of the amount added to the fiber suspension.
- fillers and coating pigments kaolin, calcium carbonate, precipitated calcium carbonate (PCC), artificial aluminum silicates and oxide hydrates, titanium dioxide, satin white, talc and calcium silicate.
- PCC precipitated calcium carbonate
- artificial aluminum silicates and oxide hydrates titanium dioxide, satin white, talc and calcium silicate.
- Another possibility of treating the rejects in the past was to partially process them with the aid of centrifugal cleaners in order to separate the fibers on the one hand and / or the coating colors and fillers on the other hand and at least partially reuse them.
- the object of the present invention is to provide a new environmentally friendly concept for treating the rejects, in particular the centrifugal cleaners, and the most complete one possible To make recycling accessible.
- the object of the invention is, in particular, to provide a method for recycling rejects, while at the same time saving energy costs and raw material costs, transport costs and landfill costs.
- rejects in particular the centrifugal cleaner from paper, cardboard and cardboard manufacture, characterized in that rejects containing fibers, coating color and / or filler, optionally with addition of water, coating color, fresh filler and / or filler slurry ground to the desired particle size distribution and used as a raw material for the paper pulp and / or coating color.
- the normally solid reject contains valuable raw materials which can be recovered with the help of the present invention and which can be returned to various paper production processes after grinding.
- the rejects from paper mills that produce coated paper or cardboard types contain a great deal of flakes of coating color. The thicker the coating layer, the more difficult it is to recover the flakes using the technology of the prior art. Double-coated varieties or coated cardboard types can be mentioned here as special examples.
- Another group in the paper industry are the SC paper manufacturing companies that lose large amounts of fillers due to rejects.
- the rejects are now ground and optionally with water, coating color, filler and / or Filler slurry added.
- the reject slurry or the ground powder is then returned to the paper production cycle for the paper pulp and / or as a coating color.
- fractions of fillers, coating color flakes, fiber suspension residues, such as, for example, fiber lumps or splinters, and foreign bodies, for example sand, can be discovered.
- the distribution of the reject material particle sizes essentially corresponds to the original distribution in the coating colors, fillers or filler / pigment slurries.
- more than 95% of the total rejects or even the complete amount can be recovered and returned to production.
- the reprocessed reprocessed according to the invention then functions, for example, as a filler, as a result of which the consumption of fresh filler or pigment can be consequently reduced.
- the grinding of the rejects is preferably installed in a centrifugal cleaner system after the last of usually several phases of a centrifugal cleaner.
- the accept from the additional cleaner system is returned to a previous phase and the remaining amount of the reject forms the final reject.
- the sieve pass obtained in this way consists of fibers, fillers, pigments, fine sand, black particles and agglomerates of fillers and pigments or pigments, fibers and fillers.
- Filler is usually understood to mean the fine particles used in the pulp; pigment means the fine particles used in the coating color.
- Flocculation and sedimentation, filtration, sieving and / or centrifugation are available as known methods for separating the undesirable constituents of the rejects.
- Flocculation and reloading often cause agglomeration in the separation processes. rate, which can now be ground according to the invention.
- Sieves are usually used for processing, preferably curved sieves for separating contaminants (broken balls, separating agents, rust, etc.). Laser measuring instruments are used to determine and control the fineness of grinding during the grinding process and the computer-aided control of the agitator ball mill system.
- the ratio of fillers and / or pigments to fibers in the rejects can vary within a wide range.
- rejects with an optionally enriched concentration of fillers and / or coating color, which are in the range from 5 to 90% by weight, in particular 30% by weight to 70% by weight is on the solids content.
- the fiber content on the one hand or the filler and / or Coating color content, on the other hand can vary, for example, from 1 to 99% by weight or 99 to 1% by weight.
- Enrichment in the sense of the present invention includes in particular the addition of fresh filler and / or fresh pigment.
- kaolin, natural or precipitated calcium carbonates, artificial or natural aluminum silicates and oxide hydrates, titanium dioxide, satin white, dolomite, mica are therefore preferably used before, after and / or during grinding as fresh pigment and / or fresh filler
- Metal flakes, in particular aluminum flakes, bentonite, rutile, magnesium hydroxide, gypsum, layered silicates, talc, calcium silicate and other stones and earths are added.
- Fresh pigment or fresh filler is preferably converted into a slurry with a solids content of, for example, 30 to 85% by weight, in particular 40 to 75% by weight, in the form of a powder, aqueous slurries containing fresh pigment and / or fresh filler in the presence of the reject and optionally conventional grinding aids and / or dispersing aids. % used.
- the added amount of fibers, coating color and / or filler is preferably 1 to 100% by weight, based on the reject material.
- the addition of water is particularly preferred in order to use the rejects ground according to the invention in a diluted slurry for the headbox. Slurries with a solids content of 5 to 50% by weight, in particular 10 to 20% by weight, are preferably used. Accordingly, according to the invention, in a preferred embodiment Milling form in the presence of water in an amount of 1 to 100% by weight, in particular 100 to 1000% by weight, based on the solids content.
- AI grain size distributions for coating pigments are known, which are also preferably adjusted using the present invention. It is particularly preferred for the purposes of the present invention that the pigments have the following particle size distribution: a) 95 to 100% by weight of particles ⁇ 10 ⁇ m b) 50 to 100% by weight of particles ⁇ 2 ⁇ m, in particular 50 to 95% by weight of particles ⁇ 2 ⁇ m c) 27 to 95% by weight of particles ⁇ 1 ⁇ m, in particular 27 to 75% by weight of particles ⁇ 1 ⁇ m and d) 0.1 to 55% by weight of particles ⁇ 0.2 ⁇ m, in particular 0.1 to 35% by weight of particles ⁇ 0.2 ⁇ m, in each case based on the equivalent diameter of the particles.
- a large variation in the whiteness and grain size distribution is also possible, which can be controlled in particular by the type and duration of the grinding. It is thus possible to mix relatively coarse fresh filler and water with a large amount of rejects on site in order to introduce this slurry into the paper pulp after grinding. In the same way it is possible to go through on site Use of a smaller amount of rejects to use them for finer grinding with fresh pigment, which then serves as a coating pigment, especially in the primer.
- the powders or slurries obtainable with the aid of the present invention can be used particularly advantageously in the paper industry, in particular for producing a coating color for the paper coating or in the paper pulp. If the fiber content is low, the rejects ground according to the invention, preferably in the coating color, are used in the paper pulp if the fiber content is high. According to the invention, good retention on the sieve is obtained. The use of the rejects ground according to the invention is particularly preferred for the production of offset paper.
- the slurries according to the invention are also suitable for the production of a coating color for lightweight, coated papers, in particular also at high application speed, and for the production of roll offset papers, in particular for the production of lightweight, coated roll offset papers, the coating of cardboard and special paper, such as labels, wallpaper, silicone base paper, self-copying, and the admixture for gravure paper.
- the coating pigment slurries obtainable according to the invention can be used in particular in sheetfed offset, in particular for sheetfed offset.
- Single line, sheet offset double line sheet offset pre-coat and sheet offset top coat
- - in web offset especially for the LWC web offset single line, web offset double line: web offset primer and web offset topcoat
- - in rotogravure especially for the LWC rotogravure single line, rotogravure double line: rotogravure pre-coat and rotogravure top coat
- - in the box especially for the double-line cardboard: cardboard primer and cardboard-topcoat and for special papers, especially for labels and flexible packaging.
- Solids content 62% Brookfield viscosity (100 / min): 1,400 mPas pH: 8.5
- Spreadable semolina from the process of a commercially available paper machine of the prior art was ground in a 15% by weight suspension to give a slurry with a grain size of ⁇ 10 ⁇ m and added to the paper pulp headbox.
