Description
The present invention relates to a method of manufacturing a lacquered wood product, and more particularly, to a method of manufacturing a lacquered wood product by lacquering wood products (e.g., wood), which intentionally induces a twist, And a method of manufacturing the product.
Generally, lacquer is a natural-friendly paint harmless to human body extracted from lacquer tree. It is also used for medicinal and edible purposes. It is an advanced painting material used in various fields such as arts and crafts, furniture, dry lacquerware.
The above-mentioned lacquer is a traditional painting technique which has been widely produced in some regions of East Asia such as Korea, China, Japan, and Taiwan. The lacquer has a good touch of the coating, a deep and calm luster, a high transparency and excellent esthetics, Good moldability does not occur even after a long period of time, and acid fastness, salt resistance, heat resistance, waterproofness, nonflammability and insulation properties are excellent.
In general, the product is molded into a product after a long drying process to prevent twisting or twisting of the wood.
A conventional method of manufacturing a lacquer wood product is a method of manufacturing a lacquer wood product by drying a knotted wood from a yard and drying it as shown in Fig. 1, (S1), and the spun wood is subjected to a primary drying process for a period of about one month (S2). The first naturally dried scratched wood is subjected to a first machining process (S3) to a thicker thickness than the product according to the shape of the product (S3). (S4). After the second drying, the primary processed product is subjected to secondary processing (curbing) according to the thickness of the desired product (S5). After the second machining, the sanding work (S6) is performed to sand the surface, and then the work is filled with porcelain or alum and then lacquered (S7) to complete the vessel do.
The general method of manufacturing such a lacquered wood product is to perform the first drying, the first molding, the second drying, the second machining, the sanding, and the lacquering after the cutting operation, Short time is required for more than 1.5 months, and the production period is very long.
In addition, since the finished product is molded by the secondary processing after the primary and secondary drying, and the lacquer is performed after finishing by sanding, it is produced only as a standardized product, so that it is produced as a standardized product without consideration of morphological aesthetic factors have.
On the other hand, although the drying method by heating and the like is sometimes applied, the thickness of the plate material is 10 cm or more even when the first cutting operation is completed. In order to remove moisture inside, There is a problem that the drying time is increased and the drying cost is increased.
In addition, since it is required to undergo a long drying process for lacquer for a long time, it is difficult to produce natural products and aesthetic characteristics because it is very difficult to produce quickly, The long delivery date has been difficult to meet the needs of consumers.
The present invention relates to a method for producing a lacquered wood product by rapidly heating wood and rapidly drying the wood to thereby produce a naturally occurring twist or deformation form as it is, thereby shortening the production period and producing a finished product which is morphologically changed by twisting of wood To thereby provide a method of manufacturing a lacquered wood product in which aesthetic elements having individual characteristics for each product are improved.
A method for manufacturing lacquered wood according to the present invention comprises:
A cutting process for drying the kneaded wood, drying the kneaded wood in the longitudinal direction of the wood for producing the product, cutting the kneaded wood into a proper size, and breaking it into the raw wood;
A processing step of processing the spiraled wood into a shape of a product;
A rapid drying process in which the molded product is artificially dried in a rapid heating manner;
And lacquering the surface of the molded product by lacquering the surface of the molded product with the twist or surface cracked by the rapid drying process.
The rapid drying method is characterized in that the surface of the product is rapidly dried by heating with a torch.
The present invention is characterized by rapid drying by an oven drying method in which a molded product is placed in an oven and dried at a high temperature within a short time.
The present invention is another rapid drying method, characterized in that a molded product is rapidly dried using a microwave-driven mechanical drying apparatus.
The lacquering process is characterized in that a plurality of times of lacquering are performed in which lacquer is applied to the surface of the molded product without filling voids caused by cracking or twisting of the molded product caused by rapid drying, do.
According to the present invention as described above, since the wood material subjected to the cutting operation is directly formed into a product shape without further drying, and the formed product is dried by a rapid drying method such as torch heating, the molded product can be dried very quickly, It can be completed within a short time from the cutting operation to the product shape processing, the rapid drying, and the lacquer work, thereby remarkably shortening the production period and mass production. In addition, since the lacquer wood product is completed by lacquering on the surface of the product which is twisted due to the rapid drying, it is possible to produce a natural aesthetic product having a morphological characteristic per each product without being shaped due to twisting of the wood .
Fig. 1 is a view showing a manufacturing process of a conventional lacquered wood product.
Fig. 2 is a process for manufacturing a lacquered wood product according to the present invention. Fig.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
2 is a process for producing a lacquered wood product according to the present invention.
As shown therein,
A method for manufacturing lacquered wood according to the present invention comprises:
(S10) of cutting a knotted wood by drying in a longitudinal direction of the wood for producing a product, and then producing a raw wood for product processing;
(S20) a step of machining the scraped wood into a shape of a product;
A rapid drying step (S30) of artificially drying the molded product by the rapid heating method;
And a lacquering step (S40) of lacquering the surface of the molded product with the twist of the molded product and the surface cracked by the rapid drying step (S30).
According to the present invention as described above, the wood-dried wood is turned in the longitudinal direction and cut to an appropriate length to perform the cutting operation S10 to make the raw wood for manufacturing the product. If the sheet is turned on in the longitudinal direction of the wood, it can prevent cracking during drying and processing and reduce twisting. Here, the broken raw material wood means wood for processing, and may be in the form of a plate, a cylinder, or a hexahedron, and it is cut into a proper shape and size according to the type of the product to be processed or the processing equipment, It is prepared as wood. In other words, in order to make a plate, a plate, a rice bowl, etc. In order to make such a thing, a tree is cut in hexahedron or cylindrical form.
As described with reference to Fig. 1, in the production of ordinary articles, the first drying step of drying the broken wood (e.g., sheet material) for one month or more and the final drying of the product by the first processing, the second drying and the second processing However, the present invention carries out a processing step (S20) of processing the broken wood into a product shape without further drying.
The processing step S20 is to process the product shape in accordance with the thickness of the final product in a single processing step. That is, in the past, the first step of the first step of machining and the second step of the second step of machining were performed to obtain the final product thickness. In the present invention, however, only one machining step (S20) .
Since the product processed into the product shape is not completely dried to the inside of the wood, a drying process is required for lacquer. In the present invention, a rapid drying process (S30) in which the processed product is rapidly heated is performed.
The rapid drying method can be heated and dried by various methods. An appropriate rapid heating method can be used in consideration of the kind of the product, the thickness of the product (thickness of the wood), or the pattern and color of the product surface. For example, a torch heating method in which a surface of a torch is heated and dried, an oven drying method in which an oven is rapidly dried, a microwave drying method in which a wood is dried by a microwave such as a microwave oven, or a heating system in a normal chamber A mechanical drying method, or the like. Conventionally, in the case of a wood discontinuously manufactured, the thickness of the wood is 10 cm or more. Therefore, it takes a long time to dry to the inside by the heating and drying method, and it is almost impossible to dry the inside without heating. Further, even when the primary processed product is dried by the heating method, since it is processed to a thickness much thicker than the thickness of the final product, it is also difficult to dry it by the heating method, requires much energy, and takes a lot of time. Conventionally, since the method of drying the wood while preventing twisting of the wood, the rapid heating method can not be used.
In the present invention, for example, a method of rapidly heating the inner and outer surfaces of a molded product, that is, a molded product using a torch, is used.
3 (a) to 3 (c) are photographs showing the shape of the product after the rapid drying of the torch according to the method of manufacturing a lacquered wood product according to the present invention.
As shown in Fig. 3 (a), the processed material according to the product shape is rapidly dried by heating the torch surface. This is less than about 2 cm even if the thickness of the article product is maximized. This is because the wooden product to be manufactured is a container for domestic use, and the thickness of the plate or the like is thin, so that the surface can be dried easily by heating with a torch as shown in Fig.
However, since the rapid drying method using the surface heating is used at this time, the twist may occur due to the characteristics of the wood. As shown in (B) of FIG. 3, when the rapid drying method is used, a crack occurs but no crack occurs. As a result, it is dried in the form of a twisted article as shown in Fig. 3 (c). It is possible to fabricate an outer shape having a different deformation for each object because it has a natural appearance by keeping the deformation itself.
Thereafter, the lacquer is subjected to a lacquering process (S40) in which the surface of the product which has been dried by the rapid drying method is lacquered on the surface of the product, thereby completing the final product. At this time, when lacquering a normal wood product, the gap or pores of the wood are filled with yellow soil, resin, or other substances, and then the lacquer is lacquered. However, the present invention adopts a method in which lacquer is applied to the surface without damaging scratches or voids generated during processing and rapid drying. This is intended to include the flaws themselves as aesthetic elements such as gaps or slight cracks, and lacquer is performed on the surface without void filling. The lacquer can be lacquered only once, but it is possible to use a lacquer method in which the lacquer is performed at least twice on the inner surface of the object.
As described above, according to the present invention, the spun raw material wood is molded to conform to the shape and thickness of the final product, and the processed molded product is quickly dried by a heating method, and the surface is lacquered while maintaining twist and scratches generated during rapid drying Finished product is completed. Therefore, it does not require a long time for drying, and the production period is shortened remarkably, and rapid production and delivery can be made according to the order, and the twisted shape is intentionally induced to lacquer in a twisted form, So that it is possible to improve the natural aesthetic expression.
