Definitions

  • Hollow glass threads are a well-known semi-finished product, for example to produce lightweight laminates by embedding them in synthetic resin.
  • Today, these products still suffer from the lack of absorbing water and other things if they are not sealed with considerable effort on their side areas.
  • sealing is not considered satisfactory in every case. All injuries to the sealing surface of a product, which can also be caused by aging, lead to an opening of the fiber, so that water can in turn penetrate there. Emptying the fiber is practically impossible.
  • This invention improves the sealing (sealing) of the hollow glass fiber by using glass or other mineral substances for the bulkheads, which are known to completely prevent penetration.
  • the process of installing the bulkheads is also cheaper in several ways.
  • the partitioning is carried out during the spinning process. On the one hand, there is no additional effort (time), on the other hand, no significant increase in investment costs is necessary.
  • the hollow glass fiber is given more or less regular spacing of bulkheads made of mineral material, primarily glass, which, as is also known from glass, completely prevents the penetration of water, other liquids and gases, in particular water gas.
  • the invention solves the problem of introducing these bulkheads into the fiber.
  • an aerosol under pressure of 10 to 500 mm water column
  • the supporting gas in which the wall material is suspended, that is, in which its rate of descent (with aerosol at rest) is reduced.
  • the support gas can continuously drive the wall material into the liquid gas cone of the spinning system.
  • the diameter of the wall material is adapted to the inside diameter of the hollow fiber. Today, for example, this is from 0.04 to 0.25 mm.
  • the aerosol maintains its temperature so low that on the one hand the wall material (such as the glass balls) remains in the desired state, on the other hand the properties of the aerosol are not undesirably changed.
  • a cannula is used as a feed line for driving in the wall material (1), the maximum inside diameter of which is not significantly larger than that of the hollow thread to be manufactured (2).
  • the cannula is insulated against heating (3) j because it has to penetrate the warm zones of the spinning system.
  • an insulating tube with low thermal conductivity is to be used for this purpose, in which a double-walled, metallic tube (4) is stored.
  • the cannula (1) is inserted on the axis of this arrangement, so that a cooling liquid or a cooling gas (5) can take over the heat transfer.
  • the sketch shows this technique, which is known per se; to understand the process.
  • the materials driving into the liquid glass cone absorb the necessary heat to connect to the wall of the thread, possibly supported by a downstream heating section.
