Definitions
- Conveyor belt often encounters the problem that the conveyor belt, which is usually made of synthetic fibers, electrostatically charges, causing undesirable adhesion of fibers and contaminants to the Conveyor belt can come. As a result, the air permeability of the conveyor belt and thus the compaction effect of
- a ductile material is understood as meaning a material which has an elongation at break of at least 10%, the value of the elongation at break relating to a conventional solid-state sample.
- electrically conductive nanofillers are used, which are already buried before the extrusion of the plastic material, it is possible, the electrically conductive
- the plastic filaments contain less than 10% filler objects, preferably less than 5% filler objects, since the mechanical properties of the filaments are then only slightly changed and the filaments are still a good one
- a high-quality conveyor belt with high strength values can be achieved if the plastic filaments are made of a synthetic polymer, in particular a polyamide, wherein preferably the filaments have been drawn before being further processed into the fabric.
- plastic filaments are made of a synthetic polymer, in particular a polyamide, wherein preferably the filaments have been drawn before being further processed into the fabric.
- Figure 2 is a schematic plan view of the compression zone of
- the conveyor belt 8 is guided by means of a clamping device 13 tensioned around the suction channel 12 and is driven to the fiber structure in the direction of arrow P1 through the compression zone 7 to transport.
- a pinch roller 1 1 which is connected to the output roller pair 6 of the drafting system 2 transmission technology, for example by means of a belt drive or a gear transmission.
- the fiber structure 9 is finally exposed to the compression effect of the suction flow.
- the pinch roller 1 1 also forms a nip 14, which limits the compression zone 7 and after which the
- Sheet of plastic filaments 15 exist, for example, a knitted fabric.
- Particularly advantageous in the conveyor according to the invention is further that this retains its electrical conductivity even after many hours of operation and even with heavy wear of the conveyor belt 8.
- this especially in the region of the nip 14, at which the pinch roller 1 1 limits the compression zone 7, causes a particularly high wear of the conveyor belt 8, which can lead to a strong reduction in conductivity in conveyor belts 8 of coated filaments 15 over time.
- objects having a nanostructure are added to a plastic melt, in particular a polyamide melt, a filler or filling material.
- a plastic melt in particular a polyamide melt
- a filler or filling material for example, silver nanorods which have a particularly high aspect ratio of 2000 have proved to be particularly advantageous.
- silver nanorods with a diameter of 50 nm and a length of 100 ⁇ m may be added. Due to the length of such silver nanorods sufficient electrical conductivity can be achieved even with the addition of a comparatively small amount of filler objects.
- a discharge can be achieved even at a voltage of 200 volts.
- these values can be easily achieved even with simple random arrangement in the plastic filaments, so with a simple addition to the plastic melt due to the length of the individual filler.
