Definitions
- the invention relates to a liner or a prepreg for mounting in pipelines,
- Such liners are used to line pipelines for drinking water
- Wastewater, etc. used if the pipes have become leaky or should be rehabilitated as a precaution to prevent leaks.
- Such liners are applied to the inner wall of the pipeline or pressed and cured in situ, in particular by irradiation with UV light.
- Such liners are advantageously in the form of so-called prepregs.
- Embossed plastic films are prepregs in the form of resin-impregnated fiber structures, in particular flat structures, before and can be kept for long periods in stock.
- the resin-moist and deformable prepregs are then introduced into the pipelines as liners, where they are applied and cured.
- Liners should be easily deformable, exactly adaptable to the inside wall of the pipe and be cheap to argue. Furthermore, liners should be readily curable and have the appropriate strength in the cured state. A lifting of the liner or the prepreg used in the course of its attachment to the pipe inner wall or during curing and also thereafter should be excluded. A liner should be easy and quick to produce, and a cured liner in a pipeline must be tightly adhered to the pipeline, have a long service life, and be resistant to wear.
- the liner or the prepreg comprises a, preferably UV-curable, resin impregnated, deformable circular knit.
- a circular knit is deformable and absorbs the resin without dripping or leakage.
- a circular knit has the best strength properties and is easy to produce. The mentioned properties are improved even further when the tubular circular knit is finished with multi-ply fiberglass yarn. This improves the strength properties and the synthetic resin absorption. If the glass fiber yarn has a weight of 1000 to 1800 tex, preferably 1200 to 1600 tex, and / or the weight per unit area of the circular knit yarn formed with glass fiber yarn is 2500 to 6000 g / m 2 , the curing properties and the attachment are positively influenced.
- the glass fiber content of the total weight of the resin knitted circular knitted fabric is 20 to 30%, preferably 20 to 27%.
- a liner or a prepreg according to the invention can be produced in a simple manner by circular knitting of glass fiber yarns and impregnations of the circular knit fabric or of the hose obtained with synthetic resin.
- the circular knitting takes place by means of conventional circular knitting machines with which glass fiber yarns are entangled.
- the knitting is done in a conventional manner with a known mesh structure. Due to its mesh structure, the circular knit or round knitted tube obtained can be stretched in all directions of the plane and can easily be brought into a desired shape or by a special application of force.
- the fiberglass yarns used have great strength and bendability. It is useful in practice if the glass fiber yarns have a weight of 1000 to 1800 tex. Thus, sufficient strength is achieved even with small amounts of resin.
- the intended basis weight of the fiberglass knitted fabric also contributes to this.
- the synthetic resin remains in the fabric, which can be applied to the surface to be covered in a manner that is readily deformable.
- the individual fiberglass yarns with a plurality of glass filaments.
- a glass fiber yarn with 1500 to 3500 threads is formed.
- polyester resins or vinyl ester resins are used in an advantageous manner.
- An advantageously used in practice circular knitted liner was created with a basis weight of 4000 g / m 2 .
- the circular knit was created with a Giasfasergarn with 1200 tex.
- the fiberglass yarn of the circular knit comprised 1200 threads.
- the Giasfaseranteil to the total weight of the soaked Rundgestricks, that is on the weight of the glass fibers and the synthetic resin, was 26%.
- the circular knit was impregnated with polyester resin and the curing of the inventively created liner was carried out by means of UV light, UV emitters were introduced into the interior of the tube located in the pipe and adapted to the inner wall of the pipe, tubular liner.
