Definitions

  • the invention relates to a method for producing a germinable paper according to the preamble of claim 1 and a germinable paper which is produced by this method.
  • Paper is a flat material consisting essentially of fibers, predominantly of vegetable origin. It is formed by dewatering a pulp suspension, whereby the dewatered fibers form a fiber felt, which is then compressed and dried.
  • Paper auxiliaries such as fillers, dyes, resin, glue, alum, flocculants, wetting agents, preservatives, slime control agents, plasticizers, etc. can be added to the pulp. depending on the paper quality to be produced.
  • the paper pulp is thoroughly mixed and adjusted to a 3% aqueous suspension, which in some cases also has to be diluted to 0.2 to 0.5% in order to be used in a paper machine, e.g. a Fourdrinier paper machine or a rotary screen paper machine.
  • the invention has for its object to provide a method for producing a germinable paper with which the paper can be produced mechanically and inexpensively while ensuring a high surface quality.
  • the invention advantageously provides that the drying device is heated to an average temperature of 75 ° C to 130 ° C, and that the paper web at a speed of about 2 to 20 m / min, preferably about 3 m / min up to 8 m / min through the drying device.
  • These parameters ensure a final dry content of the paper, which is necessary to achieve a paper quality that meets the requirements of today's printed products, such as Greeting cards of all kinds, business cards, packaging material etc. are sufficient.
  • the germination capacity of the plant seeds is preserved in such a way that the plant seeds do not germinate too early or are even killed.
  • the productivity of the paper manufacturing process is in the range up to 100 kg / h and the costs amount to approx. DM 8 to 22 / kg. So that the plant seeds are not crushed in the press device, the paper web is exposed to a maximum contact force per web width of approx. 25 kp / cm.
  • the paper web is guided in the press device between dry felt webs, the contact pressure is reduced and gentle drying is ensured.
  • the paper web's own temperature should not exceed about 75 ° C.
  • the seeds can, depending on the type and nature, be pre-swelled before being fed into the stock preparation. It is advantageous that the seeds are fed from a separate container, which has an agitator, to the stock preparation by means of a metering pump.
  • the germinable seeds can advantageously be pretreated with growth and / or fertilizers.
  • the growth and / or fertilizers can also be added directly to the pulp during stock preparation.
  • the germinable plant seeds can be coated with a material that consists of components such as. B. colors, fillers, binders, etc., are wrapped.
  • the drying device advantageously has four heated cylinders, over which the paper webs are guided by means of two felt webs. It can be advantageous for gentle drying that only the third and fourth cylinders are heated.
  • the cylinders can also be heated differently, with the maximum temperature difference being around 65% and the lower temperature limit around 70 ° C.
  • the surface of the germinable paper has a roughness depth of approx. 360 ⁇ m.
  • the grammage of the germinable paper can be approximately 150 to 400 g / m 2 .
  • Fig. 1 shows the schematic flow of the method according to the invention.
  • Fig. 1 the process flow for the mechanical production of a germinable paper is shown using the example of a circular paper machine for roll production. It should be clear that other paper making processes, such as sheet production, as well other paper machines, such as the Fourdrinier paper machine, are also suitable for the application of the method.
  • the subsequent paper properties are additionally influenced by admixing various auxiliary substances in dissolved and undissolved form.
  • germinable plant seeds 3 which are located in a separate container 4, which has an agitator 5, are pre-swollen.
  • the plant seeds are fed to the pulp 2 by means of a pump 6.
  • the pre-swollen seeds are then distributed homogeneously in the pulp 2.
  • the pulp 2 with the germinable plant seeds 3 is then fed to a machine chest 7, which has at least one circular sieve cylinder 8 which is immersed in the pulp.
  • a machine chest 7 which has at least one circular sieve cylinder 8 which is immersed in the pulp.
  • the paper stock is fed to a felt web 9, in order then to be pressed in the press device 10, which has the felt webs 11 and 12.
  • the contact pressure per web width should not exceed 25 kp / cm.
  • Infrared lamps 13 can be provided in the area of the press device 10, which gently pre-dry the shaped paper webs 14.
  • the paper web 14 is then fed to the drying device 15, which essentially has four heated cylinders 16, 17, 18, 19, two revolving felt webs 20, 21 and deflection rollers 23.
  • the cylinders of the drying The device is heated to an average temperature T of 75 ° C. to 130 ° C. and the paper web is guided through the drying device 15 at a speed v of 3 m / min to 8 m / min.
  • the numerical ratio between the temperature T in ° C and the paper web speed v in m / min is approximately 15 to 23.
  • the temperatures refer to reaching the final dry content, which is necessary to ensure a paper quality that meets the requirements of today's printed products. It is also possible to heat only the third cylinder 18 and the fourth cylinder 19. The cylinders 18, 19 can also be heated in different temperature combinations. Example:
  • the temperature of the heated cylinders should be a maximum of 65%, with the lower temperature limit of the heated cylinders being 70 ° C.
  • the paper web 14 is rolled up on a reel machine 24.
  • the squeezed water is collected in a known manner, cleaned by a substance scavenger 25 and fed back to the production process.
