Definitions

  • the invention relates to an antistatic flexible bulk container with the features of the preamble of the claim 1.
  • a fabric of this type is for the high mechanical stresses, like when using the fabric for one flexible bulk container, well suited, and through the woven electrically conductive threads will be a safe discharge reached by electrostatic charge.
  • a fabric called “electrically conductive” has a resistance to earth of less than 10 8 ⁇ .
  • Such a leakage resistance is generally required for explosion protection measures based on various technical safety regulations, including flexible bulk material containers made of polypropylene tape type "C” in accordance with the classification of the German industrial working group "Combustible Dusts / Electrostatics”.
  • the fabric has an adverse effect entails: due to the low resistance can charges become very fast and with a high charge density move and move across the entire surface of the fabric then at a point where a touch by an opposing one charged charge carrier or for example a or grounded person, suddenly discharge. thats why always before the start of a filling process that separates the charge cause a connection to the earth, resulting charges immediately from the surface of the tissue can flow off against earth.
  • GB 21 01 559 A1 is a bulk container known, which is made of a fabric in the metal threads are incorporated over the electrostatic charges of the tissue can be derived.
  • Tissues to which an antistatic is applied are also known is so that the finished fabric is electrical Can derive charges.
  • the fabric produced in this way only fulfills that as new goods Fire and explosion hazard requirements; the conductive antistatic coating according to the state the technology is not permanent, rather it is temporal is limited.
  • Equipment with an applied antistatic Coating has been used in such applications proven unsuitable in which the fabric is strong mechanical Abrasion is subject to, even with bulk containers scrape together when stacking over large areas or over be ground. With the high strains one highly stressed plastic fabric tears the coating and / or flakes. In addition, these containers are on loan used several times. Then it is particularly dangerous that the loss of electrical conductivity caused by abrasion is not recognizable during the period of use, so that protection requirements are assumed for users, that are no longer there.
  • FIBC flexible Intermediate bulk containers
  • corona discharge occurs on a charge carrier with a very small one Radius of curvature, so also on thin woven threads or on Tips on. With the corona discharge a very arises weak, limited to the immediate vicinity of the tip Discharge to the air, which is continuous and over one longer period expires, so manual grounding over ground wire is not required.
  • the conductivity of the tissue is so great that a fast charge transfer when in contact with a large charge sink and an associated sudden discharge can occur with spark formation.
  • Another disadvantage is that the antistatic, quasi-conductive It is difficult to produce threads in the known fabric and are to be processed. Already applying one metallic surface on a plastic thread formed core is complex and expensive. The antistatic Sheathing is subject to mechanical wear as before has been described for full-area coatings.
  • the antistatic thread has a cross-sectional geometry, those of those commonly used for bulk containers Ribbon tissues deviate and thus in terms of Processability causes problems.
  • the diameter of the coated thread can for reasons of Processability and mechanical resilience too not be kept as small as it would be desirable to the effect of corona discharge over the length of the thread and not only at the ends - to be able to use. Therefore can still local charge fields in unfavorable conditions form on the tissue surface that is not due to corona discharge are degradable, but degrade suddenly can.
  • thermoplastic Polymer mass is an electrically conductive Includes network of non-metallic, microcrystalline needles. This network is fusible, so that it can the usual processing methods of plastics technology is processable and with cooling of a plastic melt crystallized again.
  • the microcrystalline network is in the polymer mass is embedded and therefore wear-resistant because it not be abrasively removed from the surface of a component can.
  • the invention has for its object a bulk container of the type mentioned at the outset, the has permanent antistatic properties and thus in explosive and fire hazardous areas can be used and which, in particular, are not earthed in all applications got to.
  • the task with an antistatic flexible bulk container with the characteristics of the generic term of claim 1 in that the antistatic, quasi-conductive threads made of a thermoplastic Made of plastic in which the conductivity increases Is mixed in additive, which is a thermoplastic, thermosetting or cross-linked polymer that is electrically conductive network of microcrystalline needles is permeated as a means of forming current paths in the threads to enable a braked charge transport.
  • a thermoplastic Made of plastic in which the conductivity increases Is mixed in additive, which is a thermoplastic, thermosetting or cross-linked polymer that is electrically conductive network of microcrystalline needles is permeated as a means of forming current paths in the threads to enable a braked charge transport.
  • a fabric is called "antistatic, quasi-conductive" here, the surface resistance of which, measured according to DIN 53482, is greater than 10 8 ⁇ and less than 10 11 ⁇ .
  • the electron flow is strongly slowed down at this resistance, but is still possible.
  • Plastic tapes are understood to be in cross section have a large width in relation to their thickness and which can be processed using web technology.
  • the thread By mixing the conductive additive into the polymer mass the thread is achieved on the one hand that an electron line is made possible within the thread.
  • the specific electrical resistance of the obtained thermoplastic mixture however so high that the electron flow is possible only very slowly. This ensures that a constant flow of electrons and a constant Delivery of cargo to the environment is possible, however cannot flow as much charge in a short time, that there is a sudden high energy discharge can come under the formation of an ignition spark.
  • the thread Due to the geometry of the quasi-conductive ribbon-shaped
  • the thread has very narrow, sharp edges. On these edges Corona discharge can occur over the entire length of the ribbon take place through which constantly in controlled Wise charge from the surface of the tissue to the environment can drain off.
  • corona discharge to the Narrow edges gives the further advantage that the relative wide ribbons have a large surface and therefore one have a large capacity for receiving electrical charge. The charges are seen across the large surface of the fabric distributed, and local charge concentrations leading to sudden high energy discharges, are avoided.
  • the aforementioned can be used Establish a manual earth connection via earth clamp and cable in most applications to be dispensed with, since contactless electrical derivation Charges to the environment is enabled.
  • To form "islands" of electrostatically insulating Fabric sections in the middle of the grid made of electrically conductive Avoiding threads is the distance between the threads not less than 1 cm and not more than 5 cm. Preferably a distance of 3 cm is selected.
  • the fabric advantageously has the warp threads, the weft threads and covering the antistatic, quasi-conductive threads antistatic plastic coating made from a thermoplastic consists of a conductivity increasing additive is mixed. Through this coating it is achieved that a load is large can spread over the fabric surface and local charge peaks can be broken down.

  • acicular metal particles of macroscopic size so with about 0.1 to 2 mm in length, embedded in the matrix 8 are. These metal particles appear as fine tips on the Surfaces of the antistatic, quasi-conductive threads; on A corona spray discharge can take place at each of these tips.
  • Fig. 3 is a portion of one made in accordance with the invention Fabric 100 shown.
  • Both warp threads 3 and Weft threads 4 are tapes made of a thermoplastic material. Such tapes are easily obtained by that a film is made from the plastic, which is then cut into ribbons by a knife in the direction of the web becomes; the ribbons are then stretched.
  • There standard plastics, especially polypropylene, are also suitable and the ribbons are one in comparison to textile yarns Large widths of approximately 0.5 to 5 mm can be inexpensive large-area fabrics are produced.
