  • Storage containers for chemicals in particular for the transport and storage of high-purity, liquid chemicals for the electronics industry. Furthermore, the invention relates to the use of these materials for the production of the equipment which is necessary for removing the chemicals from the transport containers and for filling them.
  • transport containers must be based primarily on the requirements of the chemicals to be transported to exclude any contamination. This requirement is usually met by containers made from fluorinated or perfluorinated materials or from containers lined with such materials. Depending on requirements, these transport and storage containers are manufactured as unpressurized versions or as pressure containers.
  • liquid chemicals must also be removed from such containers without pressure, i. H. with the help of pumps. These pumps inevitably have moving parts, so that contamination from abrasion occurring in the pump area cannot be completely ruled out.
  • DE 36 36 886 discloses a transport container for liquid, high-purity chemicals with a double-shell inner container, the innermost lining of which is made of a fluoroplastic. Due to its multi-layer structure, this transport container is dimensioned so that it can be pressurized.
  • fluoroplastics are suitable for the production of such inner linings, which have to be produced in complex and therefore expensive processes, and on the other hand that these plastics are more difficult to process because the plastic does not have to meet the high purity requirements for the chemicals to be transported any

  • the object of the invention is therefore to provide a suitable material for the production of transport containers for liquid, high-purity chemicals and the necessary equipment, which is inexpensive to produce, while the synthesis is obtained in high purity, no or only a very low concentration of polymerization catalysts contains, can be processed in a simple manner if possible without the addition of processing aids, or only contains processing aids which do not have a disruptive effect in use or which are not leached out of the material by the chemicals to be transported.
  • the object of the invention is also to provide a suitable polymeric material from which both massive storage and transport containers for liquid, high-purity chemicals and linings for corresponding containers which can be pressurized can be produced.
  • HD polyethylene high density
  • the object is achieved by using HD polyethylene with a specific density of 0.940-0.970 g / cm 3 , in particular 0.942-0.961 g / cm 3 .
  • materials based on fluorinated hydrocarbons are suitable as materials for containers in which high-purity acids or bases are to be transported.
  • Such materials are, for example, polytetrafluoroethylene (PTFE), perfluoroalkoxy polymers (PFA), polyvinylidene fluorides (PVDF), or poly (ethylene-chloro-trifluoroethylene) (ECTFE) and are generally used with the well-known trademark "Teflon".
  • PTFE polytetrafluoroethylene
  • PFA perfluoroalkoxy polymers
  • PVDF polyvinylidene fluorides
  • ECTFE poly (ethylene-chloro-trifluoroethylene)
  • non-fluorinated plastics for the production of high quality transport containers and the associated equipment can be used for liquid, high-purity chemicals for the electronics industry.

  • these polyethylene qualities are characterized in the analysis by a particularly low content
  • Polyethylene materials which are marketed by the BASF company under the Lupolen trademark, have proven to be particularly suitable materials for the stated purpose.
  • bearing tests from this group of polyethylene specifications have proven suitable as material types, which are known under the names Lupolen 6021 D, Lupolen 5021 D, Lupolen
  • These materials are particularly suitable for the use according to the invention because they can be extruded but can also be welded without loss of quality. This results in the possibility of producing containers of almost any size by welding suitable plates from this material.
  • textile fabric By applying textile fabric to one side of these plates and anchored in the material, it is possible to prefabricate relatively thin-walled inner containers.
  • glass fiber-reinforced polyester resin By applying glass fiber-reinforced polyester resin, it is possible to manufacture stable containers which, if appropriately designed, comply with the Pressure Vessel Ordinance.
  • the construction of these containers consequently has a double-shell construction. In particular, these are interconnected shells, the inner shell consisting of the HD polyethylene selected according to the invention and the outer shell made of a glass fiber reinforced polyester resin.
  • barrier polymers suitable for this purpose are polyamide, polyester, polyvinylidene difluoride or polymers based on acrylonitrile. In this way the permeability to gases, vapors and liquids can be reduced.
  • the values given in the following tables are intended to illustrate the invention in more detail, but are not suitable for restricting the invention to the named and investigated polyethylene materials with the designation Lupolen
