Definitions
- the invention relates to a method for producing an absorption carbon fleece according to the preamble of
- Activated carbon ponds which have a grain size above 0.71 mm by means of an adhesive. It is known to use an adhesive made of natural rubber milk for this purpose.
- Activated carbon particles are obtained by glue vulcanization and thickening of the non-woven activated carbon mass.
- the known production methods include the steps of applying the adhesive to the nonwoven, pouring the activated carbon particles onto the adhesive, pressing the nonwoven activated carbon adhesive composition with the necessary pressure and thermally shaping this composition.
- a disadvantage of the known methods is the fact that the activated carbon ponds are embedded in the adhesive mass and as a result a large part of the surface of the activated carbon ponds is covered with adhesive and is not available for absorption purposes.
- FIG. 1 shows a schematic representation of a plant which works according to the method according to the invention and in which the absorption fleece according to the invention is produced.
- the system according to the invention works in continuous operation and essentially consists of five stations.
- the fleece 2 wound on a shaft 1 is combined with the tensioning device 5 by an unwinder 3 and the transporter 4.
- the fleece 2 is clamped by the unwinder 3 and the transporter 4.
- a container 6 in which activated carbon 7 is located.
- the container 6 is equipped with a metering device 8.
- the activated carbon particles 7 falling from the container 6 largely remain caught in the fabric of the fleece 2.
- the amount of the activated carbon 7 to be introduced into the fleece 2 is regulated by the metering device 8.
- a fleece made of stacked polypropylene fibers with a fiber thickness of approx. 17 dtex (10000 m fiber weigh 1.7 grams) has proven to be an advantageous material, which has a thickness of 10 mm with a mass of 200 grams / m2.
- the fleece 2 is preferably a material in which the short fibers consist of the same polypropylene material and interlock with one another and thus form a coherent formation.
- the fleece 2 can also consist of a mixture of short fibers made of different materials with different melting points, the fleece material being subjected to a heat treatment in order to fuse the different fibers together.
- the fibers with the lower melting point are melted at a temperature which is above the melting point of one type of fiber but below the melting point of the other type of fiber. This created a connection at the points of contact between the different fibers.
- the activated carbon ponds 7 remain largely in the 10 mm thick fleece 2. For those activated carbon particles 7 that fall through the fleece 2, there is a collecting zone 9 below the fleece 2. From this collecting zone, the activated carbon particles 7 can be fed back to the container ⁇ and processed further.
- a grain size of 0.71 mm has proven to be an advantageous size for the activated carbon particles 7.
- next station there is at least one heat radiator 10, which heats the activated carbon 7 and the fleece 2 in such a way that the temperature reached ensures permanent fusion of the activated carbon particles 7 with the fleece material.
- the dark activated carbon 7 absorbs the heat radiation better and is thereby heated faster than the comparatively light non-woven material.
- the hot activated carbon particles melt into the fleece material.
- the fleece 2 is heated from several sides.
- a range from approximately 144 degrees C to 148 degrees C has proven to be a suitable temperature. However, there are also other nonwoven materials that can be used at different temperatures.
- the fleece is transported on a moving support during the manufacturing process.
- this station there is also a collecting zone 9, which collects the activated carbon particles 7 that fall out during the melting process.
- the cooling station with a cooling fan 11 whose air flow cools the fleece 2 with cold air.
- the previously soft nonwoven material becomes firm again and the activated carbon particles 7 remain permanently fixed in the nonwoven material.
- the activated carbon particles 7 not fused with the nonwoven material are removed from the nonwoven by the air flow and land in the collecting zone 9.
- the last station of the system is the drive device 12 which works together with the winder 13.
- the rewinder 13 facilitates winding onto the take-off shaft 14.
- the invention is not limited to the example described, but can also be used with thinner nonwovens. Using the process with thin nonwovens offers the advantage that the to the much faster and more homogeneous
- the absorbent material produced by the present invention can be used to absorb odors and toxic gases of all kinds, it eliminates mold, fungus and allergenic dust particles. It can also be used in ventilation and air conditioning systems or as a filter for the defense industry. It can also be used for filtration in high-tech operating theaters or clean rooms.
