    [0002] Procedure of realization of a sink from flat plates of porcelain compacted ceramic material of low porosity
    [0003]
    [0004] Technical field of the invention
    [0005]
    [0006] The present invention corresponds to the technical field of realization of sinks made from flat plates of porcelain compact ceramic material of low porosity, in particular to the process of realization thereof.
    [0007]
    [0008] Antecedents of the Invention
    [0009]
    [0010] At present, there is a growing demand for products made of low porosity porcelain compacted ceramic material, due to the characteristics it offers such as high mechanical performance and a low level of internal stresses that can be machined in large parts.
    [0011]
    [0012] This material is manufactured by various manufacturers worldwide, among which the best known are the DEKTON® material manufactured by the company COSENTINO, S.A. and the one known as NEOLITH® material manufactured by the company THESIZE SURFACES, S.L., which have both similar technical characteristics.
    [0013]
    [0014] As an example of the state of the art of these materials, mention may be made of the Spanish patent documents ES2593095 and ES2593309 that define methods of manufacturing these materials.
    [0015]
    [0016] In Spanish patent document ES2593095 a compacted ceramic material with a low level of internal stresses is defined, a process for the manufacture of the ceramic material as well as the use of this compacted ceramic material as construction material in facades and coatings.
    [0017]
    [0018] In the Spanish patent document ES2593309 a compacted ceramic material with low porosity and a method for obtaining said material is defined.
    [0019] Both patents define procedures for elaboration of tables or flat sheets of large dimensions.
    [0020]
    [0021] Thanks to the size and lightness of this material, significantly increase the possibilities of design in kitchens, bathrooms, facades, walls or high transit pavements, together with the wide range of colors and designs that can be obtained.
    [0022]
    [0023] In addition, it has many advantages over traditional materials, such as a high resistance to ultraviolet rays and that its color does not degrade over time, making it a perfect material for both indoor and outdoor.
    [0024]
    [0025] Likewise, it presents a surface with high resistance to scratching and thanks to its reduced porosity, it is a highly resistant surface both to normal stains of domestic use, as well as to chemical agents. It presents a very good resistance to high temperatures without affecting its aesthetics or its properties, is more resistant to abrasion than granite and is resistant to ice and melting.
    [0026]
    [0027] This material that is presented in the form of plates has a good application in countertops and in which a flat surface is required, however, when it is intended to be used in curved surfaces, such as the bottom of a sink, it is necessary to make multiple cuts of the plate to go composing said curved form from the union and composition of said cuts. This has certain disadvantages, such as a high percentage of wastage of the material, a lot of cutting work, a low efficiency and due to all this, a high cost of the product.
    [0028]
    [0029] In addition, the result of the product is not entirely satisfactory, since it presents multiple joints and in these joints areas of accumulation of dirt are generated and are weaker areas, in which the properties of this material are affected by external factors.
    [0030]
    [0031] At present, there is a growing demand for products made with this material for its enormous advantages, but with the modes of realization existing today, no continuous products are obtained, without joints that weaken areas of it.
    [0032]
    [0033] As an example of the state of the art, mention may be made of European patent document EP0949219 which defines a method for manufacturing curved sheets of ceramic, more specifically to a process and curved oven to bend ceramic flat sheets in curved sheets of ceramic by heat treatment.
    [0034]
    [0035] In this process, a first phase of placing the ceramic sheet in an electric oven is performed in which some of the heaters are in curved disposition. The second phase is a temperature and time control to make the flat sheet heat and bend until the surface thereof contacts and conforms to the curved conformation surface of the furnace, defined by the heating elements. The furnace chamber is then cooled and the ceramic curved blade is removed.
    [0036]
    [0037] In this case it is possible to obtain a curved sheet with a certain radius, but substantial modifications of the furnace are necessary if a sheet of different curvature is to be obtained. The drawback is that it is not possible to obtain forms other than a curved surface in the form of an arc, so that the use of this material for any type of curved element is again limited and a procedure capable of offering this possibility has not been found. .
    [0038]
    [0039] It has also been shown that the heating of the low porosity porcelain compacted ceramic material to achieve a point of plasticity that facilitates its bending, causes that this material is broken when it becomes a highly brittle product and that even when cooled modifies its original color by which makes the material unusable for its use.
    [0040]
    [0041] In natural materials, such as marbles, granites, etc ... the inclination of the bottom of the sink can be made by roughing the material that forms the bottom of the sink that achieves a natural fall towards the drain, to later polish this surface. In low-porosity porcelain compacted ceramic materials, such as the one proposed to be used in this invention, this technique is not possible since it would render the material unusable.
    [0042]
    [0043] Description of the invention
    [0044]
    [0045] The method of the invention consists in the realization of a sink from flat plates of porcelain compact ceramic material of low porosity, it comprises a series of phases.
    [0046] The first phase consists of trimming the material that will constitute the bottom of the sink, material that can take the form of square, rectangular, oval plate or any other appropriate form to make said sink.
    [0047]
    [0048] The second phase consists in practicing the drain hole in the bottom of the sink, an orifice that will be made by traditional means such as cutting elements, which will generally allow the realization of a circular drain hole. This hole can be made centered on said bottom of the sink or moved to its edges.
    [0049]
    [0050] The third phase is to support the bottom edges of the sink on a flat support and apply a mechanical force on the flange of the drain hole of the bottom of the sink, mechanical force on the material at room temperature does not have any effect on the material.
    [0051]
    [0052] The fourth phase consists in subjecting this flat plate forming the sink bottom to progressive and stepped heating until reaching a heating temperature higher than the annealing temperature and lower than the melting temperature of the compacted ceramic material, without varying the physical or chemical properties of said material, in such a way that the mechanical force applied on the rim of the drain hole of the bottom of the sink deforms said surface, obtaining a continuous and inclined surface toward the drain.
    [0053]
    [0054] Then a fifth phase of cooling of the flat plate that forms the bottom of the sink takes place with the new adopted form, which consists of the cooling, which is carried out progressively and staggered until reaching the room temperature, avoiding residual stresses of the material used
    [0055]
    [0056] The sixth phase consisting of the placement of additional flat plates around the plate that forms the bottom of the sink, on the sides of it, to form the sides of the sink, joining each other by means of union.
    [0057]
    [0058] A seventh phase consisting of the external coating of the assembly made with a reinforcement of resins, glass fiber, mineral charges, etc. that increases the strength of the sink made.
    [0059] Finally a final phase consisting of the union of the upper part of the additional plates, which make up the side body of the sink, with some edges of the hole in the counter where the sink is located.
    [0060]
    [0061] According to a preferred embodiment, the heating temperature of the first phase is lower than 900 ° C.
    [0062]
    [0063] According to a preferred embodiment, the ceramic material comprises a weight percentage of the glass phase comprised between 40% and 85%, has a density comprised between 2.3 and 3.0 g / cm 3 and has an internal porosity lower than 4% in volume.
    [0064]
    [0065] According to a preferred embodiment, the means for joining the lower part of the additional plates with the first plate and the sides of the additional plates with one another are formed by a resin.
    [0066]
    [0067] In another preferred embodiment, said joining means are formed by an adhesive with color similar to that of the first plate and the additional plates.
    [0068]
    [0069] Another preferred embodiment of said invention consists in the realization of a sink body with joining edges between the rounded pieces, for which the pieces to be joined are placed on a mold that defines the shape of the sink, mold with curved edges and on which are placed the parts of the sink to be joined but without touching each other in such a way that the spaces defined between the pieces are filled with adhesive or resin of the used for the fixation of these pieces and thus when removing the mold, the joints of corner acquire the rounded shape of the mold.
    [0070]
    [0071] It is further proposed in this invention, the realization of a porcelain ceramic low porosity compacted ceramic sink, made by the previously described method.
    [0072]
    [0073] With the process of realization of three-dimensional products from flat plates of porcelain compact ceramic material of low porosity that is proposed here, a significant improvement of the state of the art is obtained.
    [0074] This is so with this procedure it is possible to make a sink with this material of suitable characteristics, in which the bottom is made with a single plate and therefore avoiding the presence of union joints in the sensitive area of the sink.
    [0075]
    [0076] As this deformation is carried out by means of a previous heating at a controlled temperature that does not exceed the melting point of the material, it does not present transformations or variations in its nature, thus maintaining all its characteristics.
    [0077]
    [0078] It is a simple procedure that is very effective to obtain three-dimensional products that thanks to it have some characteristics given by the type of material, which without this process was not possible. Furthermore, with this method, according to the place where the mechanical force or forces are applied, different curved shapes of the bottom of the sink can be obtained, not being limited to a single arc shape.
    [0079]
    [0080] Brief description of the drawings
    [0081]
    [0082] In order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization thereof, a series of drawings is provided as an integral part of said description, where, with an illustrative and non-limiting character, represented the following:
    [0083]
    [0084] Figure 1 shows a block diagram of the process of realization of three-dimensional products from flat plates of porcelain compact ceramic material of low porosity, for a preferred embodiment of the invention, showing on its side the shape of the product that is going getting.
    [0085]
    [0086] Figure 2 shows the process of union of the bottom of the sink with the side pieces that will constitute the sink by means of mold that facilitates the rounded edges of union of the pieces that will constitute the sink
    [0087]
    [0088] DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
    [0089]
    [0090] In view of the figure provided, it can be observed as in a preferred embodiment of the invention, the method of realization of a sink from flat plates of porcelain compact ceramic material of low porosity that is proposed here comprises the following phases.
    [0091] The first phase (1) consists of trimming the material that will constitute the bottom of the sink (10), material that can take the form of a square, rectangular, oval plate or any other appropriate form to make said sink.
    [0092]
    [0093] The second phase (2) consists in practicing the drain hole (11) in the bottom of the sink (10), an orifice that will be made by traditional means such as cutting elements, which will generally allow the realization of a circular drain hole . This hole can be made centered on said bottom of the sink or moved to its edges.
    [0094]
    [0095] The third phase (3) consists of supporting the bottom edges of the sink on a flat support (12) and applying a mechanical force (F) on the flange of the drain hole (11) of the bottom of the sink (10), mechanical force (F) that on the material at room temperature does not produce any effect on the material.
    [0096]
    [0097] The fourth phase (4) consists in subjecting this flat plate forming the sink bottom (10) to progressive and stepped heating (13) until reaching a heating temperature higher than the annealing temperature and lower than the temperature of fusion of the compacted ceramic material, without changing the physical or chemical properties of said material, in such a way that the mechanical force applied on the flange of the drain hole of the bottom of the sink distorts said surface, obtaining a continuous and inclined surface towards the drain (14)
    [0098]
    [0099] Subsequently, a fifth phase (5) of cooling of the flat plate forming the bottom of the sink takes place with the new adopted form, consisting of the cooling, which is carried out progressively and staggered until reaching the room temperature, avoiding residual stresses of the material used.
    [0100]
    [0101] The sixth phase (6) consists of the colocation of additional flat plates (15) around the first plate (10) on the sides thereof, to form the sides of the sink and the union (16) of the lower part of the plates. additional plates with the plate constituting the bottom of the sink and the sides of the additional plates with one another by means of joining means (16), joining means that can be resins or adhesives.
    [0102] A seventh phase consisting of the external coating of the set made with a reinforcement of resins, fiberglass, mineral charges, etc ... (20), which increases the strength of the sink made.
    [0103]
    [0104] Finally a final phase consisting of the union of the upper part of the additional plates (15), which make up the side body of the sink, with edges of the hole of the counter (17) where the sink is located, a union that also realizes with resins or adhesives.
    [0105]
    [0106] Figure 2 shows the process of joining the bottom of the sink (10) with the side pieces (15) that will constitute the sink by means of mold (18) that facilitates the rounded edges of union of the pieces that will constitute the sink. These edges (19) will be made using resins or adhesives that at these points of attachment adapt to the curved shape of the mold (18) avoiding sharp edges and preventing the accumulation of dirt during normal use of the sink.
    [0107]
    [0108] According to a preferred embodiment, the heating temperature of the first phase is lower than 900 ° C.
    [0109]
    [0110] In a preferred embodiment of the invention, it is preferably considered that the annealing temperature is 750 ° C and the melting temperature is higher than 1000 ° C, so the heating temperature must be between those two values
    [0111]
    [0112] In this preferred embodiment of the invention, it is considered that the heating temperature is lower than 900 ° C, to further ensure that the color tones of the product do not deteriorate.
    [0113]
    [0114] When the product is not heated to temperatures equal to or higher than the melting point, it is not necessary to anneal the product to release tension, since these temperatures are not generated when these temperatures are not reached.
    [0115]
    [0116] On the other hand, in this preferred embodiment of the invention, the ceramic material comprises a percentage by weight of the glass phase comprised between 40% and 85%, has a density between 2.3 and 3.0 g / cm3. and has an internal porosity of less than 4% by volume. In this case and preferably, the percentage by weight of the glass phase is 60%, the density is 2.6 g / cm3 and a porosity of 2%.
    [0117] In this report is also presented a porcelain compact ceramic sink of low porosity, made by the above procedure.
    [0118]
    [0119] The embodiment described is only an example of the present invention, therefore, the specific details, terms and phrases used herein are not to be considered as limiting, but are to be understood only as a basis for the claims and as a representative base that provides an understandable description as well as sufficient information to the expert in the field to apply the present invention.
    [0120]
    [0121] With the process of realization of three-dimensional products from flat plates of low-porosity porcelain compacted ceramic material that is presented here, significant improvements are achieved with respect to the state of the art.
    [0122]
    [0123] In this way, a process is achieved that allows to realize sinks with this type of ceramic material compacted porcelain of low porosity, with a continuous bottom, that is to say, without joints and maintaining all the properties of the same. In addition, it allows the obtaining of these products with forms that can vary depending on the areas in which the mechanical force is applied.
