Definitions

  • the invention relates to plastic barrels that serve as bung casks or lidded drums formed and as a single or Multilayer containers are produced by extrusion blow molding.
  • the invention is based on the object, the generic Kunststoffagonist for liquid and granular products in terms of to develop a safe and comprehensive grounding.
  • the Kunststoffclonétique invention is characterized by following advantages:
  • the in the non-conductive plastic material of the barrel body designed as a bung or lidded barrel plastic cup embedded strips of an electrically conductive Plastic material whose thickness is the wall thickness of the barrel corresponds, form electrical connections between the Inner surface and the surface of the multilayer barrel, the has a permanent antistatic outer layer, so that both the in the liquid product and on the inner surface of the barrel Fluid friction occurring electric charges as well the electrical charges that are due to friction on the Fcluober Diagram can form over the electrically conductive Strip in the barrel body and the permanent antistatic outer layer of the barrel to be derived in the soil.
  • the one-piece produced by extrusion blow molding Bung drum 1 made of plastic, in particular polyethylene high Density, consists of a barrel body 2 with a cylindrical Drum jacket 3, a subfloor 4, a topsoil 5 with a Filling and emptying bunk 6 and a ventilation bung 7, sunk in the topsoil 5 and their openings 6a, 7a designed as a screw plug bung stopper are closable, as well as with an upper, for piecing a barrel gripper trained support ring 8, which is an L-shaped Has cross-sectional profile.
  • Fig. 2 shows that barrel sheath 3, bottom 4 and top 5 of the bung barrel 1 of an inner layer 9, a middle layer 10 and a permanent antistatic outer layer 11 with a Leitrußanteil consist of a surface resistivity ⁇ 10 5 ohms and a volume resistivity ⁇ 10 third Ohm assured.
  • the thickness of the middle layer 10 is 1 to 2, preferably 1.5 millimeters, and the thickness of the inner and outer layers 9, 10 is 0.1-0.5 millimeters, preferably 0.2 millimeters.
  • the middle layer 10 For the production of the middle layer 10 is a recycled Granules or regrind of pure polyethylene and / or Polyethylene with a Leitrußanteil used, and as Starting material for the inner and outer layer 9, 11 is used a new polyethylene granules.
  • FIG. 3 shows a six-layer structure of the bung barrel 1 with an inner layer 9 of pure high-density polyethylene (HDPE), a barrier layer 12 made of polyamide (PA) or a Ethylene-vinyl acetate copolymer (EVA) against the permeation of Oxygen and hydrocarbons, which in two Adhesive layers 13, 14 made of a polyethylene lower Density (LLDPE) is embedded in a middle layer 10 recycled granulate or regrind made of pure polyethylene Density and / or high density polyethylene with a Leitrußanteil and a permanent antistatic outer layer 11 made of polyethylene high density with a Leitrußanteil.
  • HDPE high-density polyethylene
  • PA polyamide
  • EVA Ethylene-vinyl acetate copolymer
  • the barrel body 2 of the bung barrel 1 are as strips 16th formed, electrically conductive portions 15 of a High-density polyethylene with a Leitrußanteil integrated, the electrical connections between the inner surface 17 and the Form surface 18 of the bung barrel 1 and the strength of the Wall thickness 19 of the bung barrel corresponds.
  • the electric conductive strip 16, the bright in Fig. 1 for clarity appear parallel to the barrel longitudinal axis 20-20 over the cylindrical barrel sheath 3 and radially over the lower floor 4 and the topsoil 5 of the bung barrel 1.
  • the bung barrel 1 is on the electrically conductive strip 16th and the permanent antistatic outer layer 11 is electrically grounded, so that electrical charges attached to the inner surface of the barrel and occur in the liquid product and on the drum surface, be derived in the soil.
  • the barrel lid is made of plastic, in particular high-density polyethylene with a carbon black content, injection molded.
  • one non-conductive base material in particular polyethylene high Density
  • one electrically conductive material in particular polyethylene high Density with a Leitrußanteil
  • Another method of making the bung barrel is characterized by the coextrusion of a multilayer, tubular preform, wherein the extruder head continuously or discontinuously exiting Material hose split over the circumference and split in the cracks an electrically conductive plastic for education is injected by strips that with the tubular Homogeneous welding preform, as well as the blow molding of the Preform to a barrel body in a blow mold.
