Definitions

  • This invention relates to the refurbishment of fibreglass panels.
  • the invention will be described in relation to the refurbishment of the fibreglass linings of shiping containers, but, it is to be understood that the invention is not limited thereto.
  • the fibreglass lining of a shipping container is normally adhered to a timber panel which is usually in the form of treated plywood or sandwiched timber skins.
  • the complete inner panel consisting of the fibreglass and timber plywood is then adhered to a polyurethane insulation portion on the inside of the walls of the container.
  • the fibreglass portion of the inner panel usually consist of a planar base portion having a plurality, of spaced apart outwardly projecting portions which form batons or ribs that project into the interior of the container.
  • the fibreglass lining crazes or cracks and becomes unsuitable for use as the cracks can harbour harmful bacteria. This presents a threatening health problem especially in the transportation of consumable goods. It is difficult to remove a damaged fibreglass lining as it is securely glued to the polyurethane insulation. Furthermore, the wide variety of rib patterns in use generally prohibits use of preformed overlay panels.
  • a method of refurbishing a fibreglass panel having a base portion and plurality of spaced apart outwardly projecting portions comprising the steps of:
  • a preferred adhesive is a vinyl ester resin incorporating a filler and chopped fibreglass strands.
  • Other adhesives which may be used in cases where different conditions of the fibreglass sufaces are present include: - _ -
  • fillers need not be used if low viscosity of the resin is required.
  • lower viscosity resin is mixed with the catalyst (internally or externally) and to that mixture is added chopped fibreglass strands which come in contact with the fibreglass surface.
  • the projecting portions of the fibreglass lining wall of the shipping container are removed by a diamond saw to give a substantially flat surface.
  • the replacement panel is separately formed in a mould using a neopentylglycolisopthalic based gelcoat having from 2 to 75% flexible resin added which is then backed by 225 to 3000 grams per square meter of fibreglass wetted with a neopentylgycolisopthalic or isopthalic resin binder.
  • the fibreglass can be in the form of a mat, continuous rovings or a sheet moulding compound.
  • Various weights are used to meet the different specifications and requirements of fibreglass linings of containers.
  • the adhesive is either sprayed or screened in a pattern onto the substantially planar suface of the inner wall of the container.
  • the thickness can be approximately 6mm.
  • the preformed replacement panel is pressed against the adhesive on the insulation until the adhesive is compressed to approximately 2mm in order to achieve a proper bond.
  • the refurbishment can be achieved using split strand mats and a resin binder.
  • the surface is then finished with compatible fibreglass surface tissue.
  • Pigmented resin or neopentylgylcolisopthalic gelcoat with 0.5 to 20% wax and styrene monomer added can be used to provide the required colour and waxed surface.

Abstract

Un procédé de réfection d'un conteneur de transport ayant une garniture intérieure en fibre de verre présentant plusieurs parties espacées faisant saillie vers l'extérieur et formant des lattes ou des nervures dans l'intérieur du conteneur consiste à retirer la plupart desdites parties, de façon à obtenir que la garniture ait une surface essentiellement plane. Un panneau de remplacement, ayant plusieurs parties espacées faisant saillie vers l'extérieur, est formé dans un moule utilisant un enrobage de gel comprenant de 2 à 75% de résine flexible et une couche de renforcement en fibre de verre d'un poids allant de 225 à 3000 grammes par mètre carré. Une substance adhésive est ensuite appliquée à la surface plane et le panneau ainsi formé est appliqué par pression sur la substance adhésive, de telle sorte que les parties espacées fassent saillie à l'intérieur du conteneur.
