Definitions
- the invention relates to a method for producing Nanofo ⁇ materials according to the preamble of claim 1 and an apparatus therefor.
- Plastic films and in particular thin plastic films who almost universally used as a packaging material this ⁇ on the one hand meets a shopping bags, on the other hand, but also films that are part of food packaging.
- Disintegrating films which lead to nanoparticles made of plastic, have caused a significant concentration in the waters.
- a method for producing a product from a nanofibers containing bioplastics is known.
- a bio-plastic is meant, which is made lt Biopolyme ⁇ ren hergestel and contains lulosemaschinen the Nanozel.
- the process for producing the containing of nanofibers Bio ⁇ plastic comprises applying and distributing a mass of bioplastic with nanofibers in a flowable state onto a surface of at least one moving in a Umlaufriehtung carrier and transporting on the upper f LAE che of At least one carrier applied and distributed mass of the bioplastic in the direction of rotation of the at least one carrier.
- the bioplastic, which contains nanofibers is at least partially dried and, moreover, that the partially dried mass is detached from the surface.
- a method for producing a Nanozel lulose Plantnschi cht is known.
- the layer is applied directly to a surface of an art Stofftragmateri- than, so that the nanocellulose fibers form a thin ⁇ layer.
- the nanocrystalline suspension is here applied to an impermeable fabric web, whereupon at ⁇ closing a first drying process begins, this drying process takes place with hot air.
- After the first TRO ckenrind an additional fabric layer is placed on the upper ⁇ side of the film, said fabric layer preference ⁇ example is semipermeable, thereby forming a sandwich effect is to be generated.
- the semipermeable fabric layer should be able to pass liquids and gases.
- a second drying is carried out, wherein the three-day composite is rolled up on a cylindrical metal dryer. Heat is then passed from the dryer through the non-permeable fabric, the heat causing moisture in the nanocellulose film to evaporate and escape through the semi-permeable fabric layer.
- the two layers of fabric are necessary to stabilize the nanocrystalline film.
- the three-layer composite can also be performed on a number of more dryer units. Only after the second drying of the nanocrystalline film is gelled so far that the film without the impermeable Stützschient dried who ⁇ can. The second, semi-permeable support layer is still needed. Only after leaving the third drying stage is the film sufficiently durable that it can be further processed without a support layer. Here is of ⁇ After some that this process is very complicated, expensive apparatus required and a Oberflachennachbearbei- processing of the film is necessary.
- the object of the invention is to provide a method for producing films, can be created with the environmentally friendly films on Ba ⁇ sis of renewable resources.
- the object is achieved by a method of claim 1.
- a film of nanocellulose is produced.
- the base material nanocellulose or nanofibers made of cellulose is known.
- a large-scale processing has not yet been done because attempts have failed, so that there were only manually produced thin ⁇ layers, but can not meet the requirements of a film.
- such thin films have hitherto been produced manually and have been unevenly thick and also clearly too thick for use as a film. Apart from that, such thin films were more like a paper than a film.
- nanofibers are dissolved in a suitable solvent.
- a suitable solvent is desirable because of spe- cial nanofibers because they possess an activated Upper ⁇ surface.

- the request from the reservoir can be done with conventional known metering pumps, in particular hose or eccentric screw pumps are suitable.
- compressed air controlled containers can be used here.
- the actual film is then passed through a slurry infiltration onto a carrier material.
- the job is done via a doctor blade, which can be profiled.
- a rod with Einschliff a corresponding blade-shaped outlet nozzle, a slot or o ner-called Siide die nozzle or volume-controlled on ⁇ support nozzles.
- the layer thickness is controlled by the control of the volume or the control of the nozzle opening and the nozzle gap or the matching blade or blade.
- the rate of conveyance of the carrier material also has an influence on this.
- the carrier material is preferably a very smooth carrier material, in particular a belt conveyor, wherein the conveyor belt may be a metal or plastic belt.
- a metal band is used as a band, z. B. a steel ⁇ band used, in particular a stainless steel strip, which is corrosion resistant.
- a metal strip has thicknesses of 0.5 to 0.35 mm and, in the case of very large widths and very large conveyor roller diameters, can also reach a thickness of 1 mm or more.
- suitable and known plastics are suitable, in particular PTFE tapes or PTFE coated tapes.
- the vinasse In order to produce a thin film from the highly dispersed vinasse, which is thin at the time of application, the vinasse must be dried accordingly on the belt. However, due to the low solids content, this is a very sensitive process since such nanofiber slurries are very prone to blistering.
- the drying consists of three drying components.
- a first component is the heated carrier tape.
- the strip is warmed up with heat rollers via heat pipes, in which case in particular metal strips are advantageous.
- the temperature of the band is hereby adjusted to 40 to 95 ° C ⁇ .
- a pre-drying by means of longitudinal and transverse arrange ⁇ ter short can be performed to medium wave infrared radiator, which is preferably provided a radiator battery, in which the individual emitters are separately controllable. It is advantageous if the air supply during the infrared predrying is adjustable, ie if a transverse or longitudinal flow is present, which can set a corresponding vapor pressure in the material or above the material.
- the solvent vapor which results from the high liquid content of 95 to 99%, reliably dissipate so that it does not cause blistering or cooking or caking of the applied slurry.
- the material is rewetted after drying gegebe ⁇ if appropriate., To a predetermined flexibility, a ⁇ observed. A complete drying of the material causes it to become relatively rigid and inflexible so that targeted flexibility can be set by re-wetting.
- the subsequent moistening can be done in a steam or Nebei ⁇ comber case in which a predetermined relative air is humid adjusted stiffness and accordingly moisture is guided NAC.
- the film After drying and, if necessary, rewetting, the film is removed from the carrier bed with the aid of doctor blades and subjected to edge trimming. The edge trimmed and peeled Fol ie is then wound, with a torque-controlled winding drive performs the reeling.
- nano-materials such as nano-cellulose, which is not a plastic film in the usability by ⁇ , but is made from renewable resources, and is biodegradable.
- This film is suitable both for laminates for the electrical industry, but also for food packaging, food packaging, replacement for plastic bags, gloves and the like.
- the slip is applied in particular in a bed thickness of 1 to 20 mm and reaches after drying and stripping a thickness of 1 to 200 pm or more.
