Description

Carving technology of carbonized board by sandblasting and its products therof}

The present invention relates to a method of engraving wood charcoal plate using the sandblasting method and its production, more specifically, solid wood using a method of spraying the abrasive sand on the wood plate excellent in dimensional stability and preservation without any deformation or corrosion The present invention relates to a method of carving wood charcoal using a sandblasting method of producing letters, patterns, logos, etc., which can be expressed in embossed and intaglio according to the strengths and weaknesses of the Chosunjae and Chujae.

Charcoal, which was used only as a fuel in the past, has recently been widely used in various fields such as living materials, health materials, environmental materials, building materials, and food materials. When the heating temperature is increased, the wood turns to charcoal, which is out of the characteristics of the wood, and the charcoal after 800 ℃ or more is excellent in all characteristics of heat resistance, fire resistance, oxidation resistance, heat shock resistance and biodegradation as carbon materials. Stability. In addition, since the adsorption to harmful substances and biodegradation resistance are excellent, the use as an environmental purification material or a residential environment control material is also actively made.

In recent years, charcoal has also been used as a valuable material for architects and sculptors to create works of art.For example, the sculptor 'Seon Sun-ki' hangs hundreds of charcoal on a nylon string, or charcoal on wooden boards. The large works of pasted pine forests give new value to the charcoal arts. In Japan, attempts have been made in each area to connect small pieces of charcoal into arts and crafts. However, most of the works of charcoal so far are images of the desired works using charcoal flour or pieces of charcoal, and there are no examples of works expressing the artist's intention directly on the charcoal.

On the other hand, if you look at the production process of general writing works, the wood felling for a year or two in a well-ventilated and shaded place in a well-ventilated and shaded area to the standard suitable for making the writing works and dried well by natural drying or artificial drying method Avoid defects such as splitting, warping and bending. After finishing the drying sheet, the cut sheet is cut to fit the size of the book and the cutting surface is smoothed. After spreading evenly on the plate after cutting, place the library in the proper position according to the artist's intention and carefully rub it with a dry cloth for good adhesion. After the grass is completely dry, the engraving process is done. After finishing the engraving, remove the old paper and color it. Then, after the pigment is completely dried, paint it with natural oil (oil, lacquer, etc.) or lacquer. This traditional woodblock culture has developed into a new calligraphy culture in modern times, and the materials for writing are not limited to wood, but various materials such as wood, stone, iron, polycoat, terracotta, clay and gypsum are used. The purpose of this work is to pursue the diversity of works and the aesthetic beauty of characteristic scars, but it is also difficult to purchase and preserve wood materials, which are easy to produce, and especially to obtain wide materials.

If you put a wooden board in the air, the wooden board repeats the moisture absorption and moisture absorption according to the ambient humidity. In this process, the wooden boards have defects such as cracking or twisting due to different stresses in each part. In addition, when the humidity of the surroundings is constantly high, the moisture content of the wood board is 20% or more, and the swelling bacteria adhere to the rotting defects. Identification of harmful microorganisms in ancient books, woodblocks and banks shows that Aspergillus oryzae , Pseudomonas putidav , Tricoderma Viridae strongly breaks down the fibrous material of woodblocks, which is likely to damage the material, and the blood test results show that the blood levels are highly likely to be caused by pathogenic toxins not found in normal people.

When the organic wood board deformed and the thickening is thus carbonized at high temperature to make the inorganic wood board, there is no shrinkage and expansion due to moisture, so no deformation occurs and no nutrients are present. Recently, writing works using charcoal boards have been given high value as works of art utilizing the health of charcoal and the beauty of writing.

Patent No. 776545 `` Hazardous VOC Adsorption Carbonization Panel Using Wood Panels and Manufacturing Method thereof '' by Applicant of the Invention Establishes the manufacturing technology of charcoal plate without splitting or twisting wood plate such as fiber board under anoxic compact The charcoal plate has a number of beneficial properties such as humidity control by the unique micro-pores of charcoal, adsorption of harmful substances, electromagnetic shielding and fire and gas and flames. In addition, the patent application No. 2009-65749 `` Writing products using a charcoal board and a method for manufacturing thereof '', which the applicant of the present invention is currently applying for the patent, first engrave desired letters or pictures on the MDF, and then recall the carved MDF. It is a technology that completes the writing work of charcoal board by carbonizing and coloring with registered patent technology.

However, the writing of wood materials is possible only by the writing expert, and the carbonization of the first written wooden board without splitting or twisting is possible only by the charcoal expert with the special carbonizing device. Sculpting by hand using charcoal boards made by charcoal specialists has the disadvantages of severe wear of the blades and deterioration of the surrounding work environment caused by powdered charcoal powder produced by the charcoal expert. Even if it is rejected, the same work cannot be made, and in the process of carbonizing it again, there is a problem in that shrinkage occurs differently due to a slight difference in carbonization conditions, so that it is impossible to produce the same work.

Therefore, if a new technique that can be written by mechanical work using charcoal boards that are already made and marketed by charcoal experts emerges, there is an advantage in that the same works can be produced in large quantities.

The present invention has been made to solve the above problems, the object of the present invention, there is no deformation or corrosion at all, using the sandblasting method on the wood plate excellent in dimensional stability and preservation, the strength and weakness of the wood raw material and the wood harvesting part In order to provide engraving and engraving products of charcoal boards using sandblasting methods to produce letters, pictures, patterns, logos, etc. that can be expressed while embossing and engraving on wood boards.

In order to solve the above problems, the engraving method of the charcoal plate using the sandblasting method according to the present invention, using the wood charcoal board carbonized MDF with a veneer, as the material, the hardness of the spring member and the versatile portion of the charcoal plate Applying a primer to make use of the difference; Attaching a library or a painting in which letters or pictures are made to the charcoal board; Removing a portion of the library or the warehouse to which abrasive sand particles are to be sprayed from the charcoal board; Sandblasting the abrasive sand particles to the charcoal plate is produced by the step of embossing or engraving the pattern on the library or warehouse, the charcoal plate is 0.2 ~ 1.0㎜ thick veneer in MDF before carbonization It is characterized by being attached and carbonized.

Preferably, after the step of applying the coating agent, further comprising the step of applying a coating agent that can give gold powder, silver powder or color to the charcoal plate, and the step of coloring after the step of forming a pattern It may further include, in the coloring step to coat the upper coat (上 塗) with a thickness of 0.01 ~ 0.1㎜ to accurately and clearly express the embossed or intaglio of the charcoal board.

Preferably, the abrasive sand particles sprayed in the sand blasting operation is a diamond steel or glass beads, the size of these particles is 70 ~ 325 mesh (mesh), the pressure for spraying the particles is 1 ~ 4 bar ( bar).

When charcoal is lumbered, the small and small micropores that delivered the moisture and nutrients inherent to the tree are further reduced to one-third the size and are produced in large quantities, thereby increasing the adsorption power to harmful chemicals such as formaldehyde and ammonia, and especially higher than 800 ℃. The charcoal plate manufactured at temperature has high electrical conductivity, which greatly increases the far-infrared emissivity and the electromagnetic shielding effect. Also, when the product is made of charcoal, the charcoal plate does not cause any dimensional fluctuations such as length and thickness even by moisture. As it is manufactured and is inhomogeneous, mold and bacteria cannot be inhabited, so the lumberjack product made of charcoal boards does not need special management, but only by storing it, humidity control function, far infrared ray emission function, electromagnetic shielding function, harmful Due to the substance adsorption function and the like can provide a beneficial effect on health.

Engraving method of the charcoal board using the sandblasting method having the characteristics as described above and the product produced by the technique, natural wood and permanent preservation is possible by keeping the tree ring feeling on the completely burned charcoal board as it is, As it can express not only tree rings, but also pattern patterns, pictures, and characters, it is highly valuable in all fields and is semi-permanently preserved without special management, so it can be used in various ways as a valuable material for producing new writing art. And added value is very high.

In addition, the engraving method and the product according to the present invention, since the product is already made of carbonized charcoal board, no dimensional fluctuations or deformation occurs under any conditions such as humidity or temperature even after production of the work. Since the same product can be mass-produced by machine work, the creation of writing products using charcoal board means the birth of a new art field, and the method of manufacturing writing art works using charcoal board is innovative and original art technique. Will be.

Sandblasting technique is a decorative technique that sprays abrasive particles at high speed with compressed air on the surface of the material to be polished to make it appear as if it is frosted on the glass surface. It is an etching technique that can give (unevenness) and express contrast.

The charcoal board used for the engraving method of the charcoal board using the sandblasting method according to the present invention may be a charcoal board carbonized with MDF (Medium Density Fireboard), but 0.2 to 1.0 mm thick in the MDF before carbonization. By attaching and carbonizing the veneer of wood, it is used to display annual rings (Chunjae part and autumn part, namely rings) on the charcoal board. As the veneers that can make use of the strength difference between the spring part and the autumn part on MDF, ash wood, oak, Hardwoods with high specific gravity, such as zelkova, are preferred.

The method for manufacturing such a charcoal plate has already been patented by the applicant of the present invention, and since the present invention is not a patent on a method for producing such a charcoal plate, a detailed description of the method for producing a charcoal plate will be omitted. The technique of carving on the charcoal plate is basically a step of applying a primer to the charcoal plate, attaching a library or a firebox to the charcoal plate, and removing a portion of the library or firewood to spray abrasive particles from the charcoal plate. Basically, you will go through the steps of forming a pattern on the charcoal board.

In the step of applying the undercoating agent to the charcoal plate, a charcoal plate carbonized with MDF, preferably an MDF carbonized with veneer, is used as the material of the charcoal plate, and the rings of the charcoal plate To apply the difference in hardness of), the coating is applied twice, and the coating acts as a kind of adhesive to prevent the color of the coating from leaving the charcoal board. . Transparent synthetic paints such as paint-based primers, epoxys, ceramics, or the like, or mixtures of water and adhesives, adhesives, natural paints, and other sticky materials may be used. Such an undercoating agent acts as an adhesive, but also serves to prevent subsequent colorants from penetrating the charcoal board, and in order to make use of the strength of the spring and autumn portions of the veneer attached to the surface of the charcoal board, it is 0.01 to 2 times. It is preferable to apply | coat to 0.05 mm thickness.

When sandblasting abrasive sand particles are sprayed, the grains are shaved with the same strength, so the hard or weak glyph pattern represented by the lumberjack and the lumberjack provides the intaglio or embossment of the charcoal board depending on the coating thickness of the primer or topcoat. The precision and clarity of the

Libraries or paintings are works created by writing letters, paintings, or patterns on a sheet or sanding film, or by hand painting them on a charcoal board. In Esau, such a library or a firewood is attached to a charcoal board, and then, the sandblasts are sprayed from the library or the firewood to remove a portion to be dug from the charcoal board. In other words, if you want to form an embossed form, remove parts except letters, pictures, and patterns from the library or the painting. Conversely, if you want to form engraved forms, you can add letters, pictures, or patterns from the library or painting. Remove

In the step of forming a pattern on the charcoal plate, the abrasive particles such as glass beads or aluminum oxide are sprayed on the charcoal plate to form letters, pictures, or patterns by embossing or engraving them. Form. If the pressure to inject the particles is too strong, it is difficult to control the depth to dig the charcoal board, so it is preferable to set the injection pressure to about 1 to 4 bar, and if the particle size is too large or small, Since it is difficult to control the fineness of the particles, it is preferable to use particles having a size of 70 to 325 mesh (diameter 212 to 45 μm).

For coloring of letters, pictures, patterns, etc., after applying the primer, the coating agent may be coated with charcoal or silver powder or color, or to form a pattern. It may further comprise the step of coloring later. If the process of coloring is performed, top coat is applied to the thickness of 0.01 ~ 0.1mm three to four times in order to express the embossed or intaglio formed on the charcoal board accurately and clearly, and white acrylic or lacquer for color coloring. It is preferable to apply | coated a desired color after apply | coating several times, and as a top coat used for top coat, the material which adheres well with the undercoat, such as gold powder, silver powder, and a colored paint, is preferable. Of course, in order to maintain the adsorption performance of the charcoal as much as possible in the coloring step, the charcoal powder should be blown and painted, and if you apply a primer to the charred part of the charcoal board, the rings of the tree will appear more clearly.
