Definitions

  • the invention relates to a process for treating wood in which a wood preservative is inserted into one or more recesses made in wood, whereupon these recesses are closed outwardly.
  • the treatment of wood with a wood preservative aims at protecting the wood pre- ventively or curatively against attack by moisture, micro-organisms (for instance Basidiocymetes, Asomycetes), insects (for instance termites, Hylo- tropus Bajulus, Anobium Pictatum).
  • micro-organisms for instance Basidiocymetes, Asomycetes
  • insects for instance termites, Hylo- tropus Bajulus, Anobium Pictatum.
  • a similar process is generally known.
  • a capsule is used.
  • the process followed is then that first a hole is drilled in the wood, subsequently a glass capsule with the wood preservative is inserted into it and finally the drilling hole is closed with a plug, which is applied in it in a recess, in result of which the capsule breaks and its contents are freed and spread in the wood.
  • a drawback of this process is that wooden beams, window-frames, etc. forming part of supporting structures or wooden elements which are regularly charged, are weakened as a consequence of the remaining holes.
  • Another drawback is that the user of the capsules when breaking the capsules may come into contact with the contents thereof.
  • the invention provides a process which meets the above-mentioned drawbacks.
  • a solid material is applied in the recess together with the wood preservative in such a way that this solid material at least partly fills up the recess, said solid material having a reinforcing effect upon this wood when it absorbs water and expands in consequence thereof and/or when a permanent pressure is exerted upon it.
  • wood is applied having a lower water content than the wood treated, most preferably resin-free splint-wood or heart-wood.
  • Splint-wood is young wood and has a less resin-rich cell structure than has for instance heart-wood. This property is of importance in view of the absorption capacity of the wood and the capacity to absorb free liquid.
  • the wood material that is applied in the recesses of the wood to be treated in such a way therein that the wood preservative present therein is released in the direction of the fibres of the wood material applied.
  • the fibre direction of the wooden plug is the radial direction so that the fibre direction is the same as that of the surrounding wood.
  • wood contains water.
  • This water can be present in two forms, to wit bound to the cell walls, the so-called inhibition water, and as free water in the cell cavities and vessels.
  • This water is usually indicated as capillary or occlusion water. This water is present only if the cell walls are completely saturated.
  • the free water disappears from the cell cavities.
  • the inhibition water amounts to about 29% at a maximum.
  • a wood humidity of about 17% is created, at which a shrinkage of 1.25% in radial and 0.1% in the fibre direction occurs.
  • a deal plug which is provided with a wood preserving organic agent and a moisture content of about 10%, will expand after application in the wood to be treated which is in constant contact with the open air and in result thereof has a higher moisture content.
  • this has on the surrounding wood also a stabilising effect occurs because the moisture content of the plate treated decreases. This is in particular important for critical spots sensitive to wood attack. For if here the moisture content will surpass 21% the chance that the wood decay fungi most occurring in Europe, such as Polystictus versoclolor, Coniopohra Puteana, Gloephillum tradeuym are developed, is very great.
  • the invention also relates to a product for treating wood, comprising a wood preservative, and an absorbing material having a moisture content below 16% which expands on absorption of water, which material is enveloped by packing material which should largely be removed prior to use.
  • this envelope consist of a capsule of smashable material, for instance glass.
  • the absorbing material consist of wood, most preferably splint wood.
  • cork is considered because it is a bit compressible. For if no protecting wrapping is applied it is advantageous to have the product according to the invention which is applied in a recess of the wood to be treated, taper a bit, so that the diameter of the portion of the plug which closes the recess present in the wood to be treated from the outside is somewhat larger than the bore-hole.
  • the plug is anchored even more fixedly and no wood protective agent or glue which is present in the plug, can escape along the plug. If one wishes to glue the plug in the recess, one applied glue at the head of the plug and/or along the plug. By providing the plug with a recess, any excess of the glue is caught herein, so that the glue cannot come into contact with paint applied on the outside of the plug. In result thereof discoloration of the paint is prevented.
  • the portion of the plug applied in the recess last is not oversaturated with the wood protective agent. This is of great importance in applying the plug for the sake of security of the users. Also, this has the great advantage that the wood protective agent cannot splash or run off after opening the packing or can run off in open seams of window frames.
  • the impregnated plug can be provided on one end with an impermeable medium, for instance a galvanized wood screw, which closes the whole boring hole opening when applied. It is also possible to apply a non-impregnated plug on one end which by means of a compressible sealing disc for instance of aluminium foil is separated from the impregnated portion.
  • the plug according to Figure 1 substantially consists of absorbent material having a low water content, for instance cork, wood flour, wood shavings, etc. Portion 1 is not impregnated with a wood protective agent.
  • Portion 2 is impregnated with the wood preservative. Both portions are mutually separated by a film of compressible material 3, which may for instance consist of a remainder of the packing material in which the plug was packed before use or of glue or resin. Partition 3 prevents the wood preservative in the impregnated portion 2 from penetrating in the non-impregnated portion 1, when in applying the plug in a recess of wood pressure is exerted on portion 1. If in the absorbent material a glue is present, the glue runner 4 sees to it that any excess of glue present cannot escape outwards.
  • connection between the non-impregnated and impregnated portions is realized by means of a galvanized headless iron screw 5.
  • a screw made of plastic material, for instance polyurethane, is considered.
  • connection between the non-impregnated portion and the impregnated portion of the absorbent material is effected by means of a bayonet catch.
  • a spring 6 on the inside and a compressible packing both portions can expand without the total length of the plug being influenced. This is of great importance in view of the stability of the plug in the wood and for a paint layer applied thereover.
  • Figure 6 also relates to an embodiment with a glass wrapping.
  • a galvanized iron screw 9 is present.
  • the screw When placing the capsule the screw will smash the glass wrapping and will in consequence be anchored fixedly in the surrounding absorbing material.
  • This embodiment has the advantage that no glue need be used, whilst moreover no wood protective agent can escape along the screw. There is no chance of splashing when applying the capsule either.
  • the whole can be finished with a wood repair agent, so that also the substrate for the paint system to be applied over it is fully suitable for applying the paint over it.
  • a flat screw 9 of galvanized iron or a plastic and a closed capsule of glass use is made of a flat screw 9 of galvanized iron or a plastic and a closed capsule of glass.
  • the capsule is surrounded by a thin foil of plastic, for instance polyethylene foil or of polyvinylchloride foil.
  • the whole is constructed such that after application of the glass capsule in the boring hole the capsule can be smashed by screwing the screw on.
  • the wood protective agent can penetrate the wood to be protected.
  • the capsule with screw can also be wrapped in nylon or galvanized gauze (8). Also this packing need not be removed, no more than a wrapping of plastic foil before applying the capsule in the boring hole.
  • This embodiment has the advantage over the known capsule, the wrapping of which consists wholly of glass, that after inserting the capsule into the boring hole, the screw applied as closure is inserted into the boring hole simultaneously with the capsule.
  • a closing plug is to be applied in a separate act. It then could happen that such a plug was inserted after it had been forgotten to apply first the glass capsule. This is impossible when applying a closing screw, which is applied integrally with the capsule.
  • Figure 10 relates to an embodiment in which use is made of a unit consisting of a sealed capsule (8) of smashable material, for instance glass, filled with a solution of a wood preservative and a plug (1) of material impermeable to wood preservative, for instance heart-wood, fixedly connected therewith for instance by glueing.
  • a wood preservative for instance wood
  • the plug consists of hardwood, in particular of European oak, the plug moreover does not deform in smashing.
  • the plug is internally provided with a cavity (12) into which a protruding portion (13) of the sealed capsule fits, yet a relative large amount of wood preservative can be taken up into the unit, although a large part of the length of this unit is taken by the plug. This is in particular of importance when treating wood structures having a smaller thickness, for instance window-frames.
  • the wrapping material of the capsule for instance the glass such that it does not transmit ultraviolet light. This promotes the keeping qualities of the wood preservative present in it.
  • wood preservative is to be understood in the broadest sense.
  • agents which as such do not exert a killing effect on living organisms, but see to a medium in which living organisms cannot multiply are meant.
  • a solution of paraffin in an organic solvent can be applied. When this solution penetrates into the spaces between the wood fibres and the organic solvent evaporates partially, the paraffin remains in the spaces, in result of which no living organisms can develop therein.
