Definitions
- the present invention relates to a process for upgrading wood panels formed by large oriented particles.
- This invention falls within the field of interior decoration, and more particularly in the field of cabinetmaking and the manufacture of furniture and interior fittings.
- This invention is remarkable in that it makes possible, for such applications, the implementation of wooden panels consisting of layers of compressed wooden slats then glued using resin and/or wax.
- Some panels of this type are known to those skilled in the art under the name OSB, abbreviation of the Anglo-Saxon expression “Oriented Strand Board”.
- OSB-type particle boards usually have a very irregular surface condition, even dangerous to the touch, and are therefore generally only used as construction materials.
- framework unsuitable for use as a raw material for the manufacture of finished products such as furniture components.
- the method according to the invention aims to provide added value to reconstituted wood panels having in their raw form an irregular surface condition and usually intended for structural uses, by providing a treatment of these panels intended to give them new surface, chromatic and aesthetic characteristics favoring their use in the field of interior decoration in general and furnishing in particular.
- the invention presents a process for upgrading a wood panel formed by large oriented particles, including at least a first step of coloring by means of a coloring product and a first step of sanding of said panel, said sanding being carried out to a sufficiently great depth so that certain surface particles are exposed, but sufficiently shallow so that other particles remain covered with the coloring product.
- the invention makes it possible to give a particle board an at least bichromatic appearance on the basis of the natural color of the wood forming the panel and the color of the coloring product which is applied to it during the first stage of setting. color, as well as a substantially rectified surface condition thanks to the sanding step which will have simultaneously allowed the partial re-emergence of the said natural color of the wood.
- the coloring product may be constituted by a pigmented solution or by a more or less diluted lacquer, for example up to 50 to 80%, or even in certain applications by an undiluted lacquer.
- the method described above includes at least a second coloring step subsequent to the first coloring step.
- Such a second coloring step will give the panel a polychromatic appearance. Indeed, on the parts where the natural wood will have been made flush at the end of the first sanding step, the color applied during the second coloring step will come out as it is, whereas, on the parts that will have emerged intact at the end of the first sanding step, the resulting color will consist of a combination of the colors used for the first and second coloring steps, which will give the panel a chromatic depth unprecedented in the current state of the art .
- the last coloring step is followed by at least one other sanding step which will give the panel an even smoother surface finish.
- the invention also relates to a wooden panel obtained by the implementation of a method as described above.
- the invention also relates to a piece of furniture including at least one wooden panel obtained by implementing a method as described above.
- the invention also relates to a decorative element including at least one wooden panel obtained by implementing a method as described above.
- the invention relates to a system for upgrading a wood panel formed by large oriented particles, including at least means for coloring said panel by means of a coloring product and means for sanding said panel, said sanding means being able to be configured so that the sanding is carried out to a sufficiently great depth so that certain surface particles are exposed, but sufficiently shallow so that other particles remain covered with product dye.
- FIG 1 is a flowchart which represents a method in accordance with the principle of the invention.
- FIG. 1 presents in the form of an assembly of three top views the appearance of a particle board obtained after the implementation of a coloring step and a sanding step according to the invention
- FIG 3 is a succession of diagrams illustrating successive sections of the surface of a particle board after implementation of a coloring step and a sanding step according to the invention.
- FIG 4 is a flowchart which represents a method according to an advantageous variant of the invention.
- FIGS. 1 and 2 to be considered together, illustrate a method in accordance with the principle of the invention and the result that it allows to obtain.
- the method described here by Figure 1 includes at least a first step PLQ1 of coloring a particle board PIB by means of a coloring product and a first step of sanding SAND1 of the P1L panel resulting from this setting. in colour.
- the sanding carried out during the first sanding step SAND1 is carried out over a sufficiently large depth PRP1 for certain particles of the particle board P1L present below a first so-called surface level NSI are exposed, but sufficiently insignificant for other particles of the particle board P1L present above a first so-called lower level NCI to remain covered with the coloring product.
- the invention makes it possible to confer on the PIS particle board resulting from the implementation of the method described above an at least bichromatic appearance on the basis the natural color of the wood forming the PIB panel and the color of the coloring product that will have been applied to it during the first coloring step PLQ1, as well as a surface condition substantially rectified thanks to the sanding step SAND1 which will have simultaneously allowed the partial re-emergence of the said natural color of the wood.
- the above method also includes a VARN1 varnishing step, which can consist of a simple single-layer application of a varnish, sometimes called the "blocking" step. in the vocabulary of cabinetmaking, and then aims to make the surface of the PIS panel as it results from the sanding step SAND1 less permeable to a new application of coloring product in a variant of the invention which will be described below.
- a VARN1 varnishing step which can consist of a simple single-layer application of a varnish, sometimes called the "blocking" step. in the vocabulary of cabinetmaking, and then aims to make the surface of the PIS panel as it results from the sanding step SAND1 less permeable to a new application of coloring product in a variant of the invention which will be described below.
- the varnishing step VARN1 may on the contrary not be a simple "blocking" step, but a real finishing step then generally consisting of a cross application. at least two coats of finishing varnish.
- FIG. 3 presents a succession of diagrams illustrating successive sections of the surface of a particle board after implementation of a coloring step and a sanding step according to the invention.
- the diagram arranged in the upper position schematically represents a surface condition of a PIB particle board in its raw state.
- This surface state is represented by a curve SP1B having a shape which has been chosen arbitrarily and does not constitute a representation intended to give an exact account of reality.
- the diagram arranged in the middle position schematically represents a section of the surface of a P1L particle board in a state resulting from a first coloring step as described above.
- the surface previously represented by curve SP1B is covered with a layer of coloring product, illustrated by a thicker line, and the panel P1L thus has a colored surface SC.
- the diagram arranged in the lower position schematically represents a section of the surface of a PIS particle board in a state resulting from a first sanding step as described above. This sanding was carried out to a sufficiently large depth PRP1 for certain particles of the P1L particle board present below a first level called the NSI surface to be exposed, but sufficiently small for other particles of the panel P1L particles present above a first level called lower NCI remain covered with the coloring product.
- the surface of the PIS panel no longer has the shape previously represented by the curve SP1B, which has been truncated at the places where the sanding operation has removed material and where the raw material which constitutes the heart of the panel is again visible. Consequently, the surface of the PIS panel obtained at the end of the sanding step has a bichromatic appearance due to the coexistence of sanded areas SP where the raw material is visible and colored areas SC which have remained covered with a layer of coloring product, because located below the sanding depth PRP1 and which were therefore left intact during the sanding step.
- Figure 4 is a flowchart which shows a method according to an advantageous variant of the invention, which aims to give a particle board a polychromatic appearance.
- a method as described above further includes a second step of coloring PLQ2 of the particle board PIS by means of a second coloring product and a second step of sanding SAND2 of the surface of the panel resulting from this second step of coloring PLQ2.
- the sanding carried out during the second sanding step SAND2 is carried out on a second depth PRP2 measured from a second surface level NS2 resulting from the first sanding step SAND1 and from the second PLQ2 coloring step.
- This second depth of PRP2 is large enough for some particleboard particles present below a second surface level NS2 to be exposed, but sufficiently insignificant for other particles of the particle board present above a second lower level NC2 to remain covered by the coloring product implemented during the second coloring step PLQ2.
- the second lower level NC2 will advantageously be chosen higher than the first lower level NCI, which will allow coexistence, on certain surface elements of the panel, of the two colors implemented during the first and second stages. coloring, but also, in other places of the panel, a superposition of said colors resulting in a third shade in addition to the natural shade of the original wood panel, i.e. an unprecedented polychromatic appearance in the current state of the technique.
- a yellow pigment tint during the first coloring step PLQ1 followed by a first sanding step SAND1 will make it possible to obtain a panel presenting in its most hollow surface zones a yellow tint, in other places closer to the surface a green tint resulting from the superposition yellow tints, in other places even closer to the surface of the panel a blue tint and finally in its most superior zones the natural tint of the original panel.
- the second sanding step SAND2 is followed by a second varnishing step VARN2 similar to the first varnishing step VARN1 and aimed at achieving a blockage making the surface of the panel resulting from the step less permeable to a new application of coloring product during a possible third cycle of coloring and sanding.
- the second coloring product used during the second coloring step PLQ2 may consist of a lacquer diluted and applied in one pass. rapid and thin, operation known to those skilled in the art as the application of a "veil”, which will have the function of altering the overall appearance of the panel by mixing color and will not necessarily be followed a second sanding step SAND2.
- the resulting panel can then undergo a second varnishing step VARN2 which will constitute a true finishing step by cross-application of at least two layers of finishing varnish.
- Another variant of the invention aims to give a wood panel a quadrichromatic appearance on the basis of a trichromatic appearance panel obtained by implementing a method as described in Figure 4, in which the second coloring step PLQ2 is followed by a sanding step SAND2 and a varnishing step VARN2 aimed at performing a simple blocking and not a true finishing step.
- the process as described in FIG. 4 includes a third coloring step by applying a veil preceding a third varnishing step which will constitute a true finishing step.
