Definitions

  • Two-chamber cartridge for solidifying rock or coal
  • the invention relates to a two-chamber cartridge according to the generic concept of claim 1.
  • Such two-chamber cartridges are known from DE-PS 23 45 913, in which the partition between the chambers made of a water vapor-tight material, for. B. consists of a polyvinylidene chloride film or a composite film. Polyamide coated polyethylene is proposed as the film material for the composite film. The use of a water vapor-tight composite film reduces the water vapor diffusion and thus prevents the curing of the isocyanate. The storability of two-chamber cartridges is thus improved. In DE-PS 23 45 913 it is stated that such a cartridge was still completely unchanged after 3 months. However, if the cartridge is stored for even longer, signs of solidification appear after 6 months.
  • the invention has for its object to achieve an even better Lagerf ability of the two-chamber cartridge.
  • water-glass solutions and polyisocyanates according to EP-PS 00 16 262 can also advantageously be used in the two-chamber cartridges according to the invention. Two-chamber cartridges with these substances can also be stored almost indefinitely if the inner cartridge is equipped with such composite films.
  • the single figure shows a longitudinal section of a two-chamber cartridge 1, which consists of two film tubes 2 and 3, which have different diameters and are inserted into one another, so that they form two chambers 4 and 5 which are separated from one another.
  • the two film tubes 2 and 3 can be closed together at their ends by a clip 6.
  • Example 1 comparative example
  • a two-chamber cartridge with a length of 300 mm consists of an outer cartridge with a diameter of 43 mm and an inner cartridge with a diameter of 32 mm.
  • Diphenylmethane diisocyanate is located in the inner cartridge.
  • the polyol component is located in the outer cartridge.
  • the walls of the outer film consist of polyamide film with a wall thickness of 40 to 45 ⁇ .
  • the inner cartridge consists of a polyamide / polyethylene composite film with a total thickness of 100 ⁇ m. The two-chamber cartridge was stored. After 6 months, signs of hardening appeared.
  • the wall of the inner cartridge consists of an aluminum composite film laminated with polyethylene film and polyester film.
  • the two-chamber cartridge showed no signs of hardening after a storage period of 2 years.

Abstract

L'invention concerne une cartouche double chambre pour durcir de la roche ou du charbon par introduction de constituants en polyuréthane. Dans une cartouche de plus grand diamètre (2) renfermant un polyol est disposée une deuxième cartouche (3) de plus faible diamètre constituée d'une feuille composite étanche à la vapeur d'eau, dans laquelle se trouve un diisocyanate de diphénylméthane. La deuxième cartouche se présente sous la forme d'une feuille composite aluminium/plastique soudée de manière tubulaire, et ladite feuille se compose d'une feuille aluminium doublée d'un film polyéthylène et d'un film polyester, ou bien peut être constituée d'une feuille aluminium doublée PVC deux faces.
