The present invention is to enable the use of various products by molding MDF (Medium Density Fiberboard, hereinafter referred to as "MDF") to charcoal,

More specifically, after forming a variety of products using the processed MDF manufactured by the charcoal by the heating method, the charcoal molding using the MDF (MDF) to maintain the strength to provide the efficacy of the charcoal as it is maintained And to a method for producing the same.

Benefits of Charcoal

Regarding a method of manufacturing a molded article or a molded article using a conventional charcoal, Korean Patent Publication No. 2003-68097 (published Aug. 19, 2003) and Patent Publication No. 2003-58981 (published Jul. 07, 2003) have.

Patent Publication No. 2003-68097 is composed of charcoal powder as the main material and heat treatment, surface polishing, cooling, etc., with the various impurities added to the charcoal powder to perform separate treatment such as charcoal itself to increase its strength, Hygroscopicity and surface discoloration prevention function.

Patent Publication No. 2003-58981 discloses a coating layer formed by mixing a fine powder of charcoal, volatile powder, ash and wood vinegar at a predetermined ratio to form a certain shape and then heating and reheating the mixture of a fine powder of charcoal and Teflon fluorine resin solution. There has been proposed a method for producing a carbon molded body that can be formed to prevent the food from sticking or burning.

However, the conventional method of manufacturing a molded article or molded article is that the charcoal is made of wood, and then the charcoal is prepared by mixing the other impurities, so that the charcoal cannot provide a unique function of the charcoal.

'MDF' is an abbreviation of Medium Density Fiberboard, and it extracts fiber by crushing several kinds of wood, especially long fiber, and separates the fiber for both surface and core and adds adhesive to build up a layer and press. Press) to refer to a product that has been surface polished.

Therefore, the characteristics of the product are determined by the two raw materials of MDF: wood, adhesive and press strength. That is, the color of the MDF is determined depending on the color of the tree and even the bark, and its properties also depend on whether the adhesive is water resistant.

In addition, it can be classified into LDF (Low Density Fiberboard) or HDF (High Density Fiberboard) depending on how much pressure it is made to have a density.

In general, MDF mainly produced and used in Korea has a weakness against moisture and water by using UF (Urea-Formaldehyde, Urea-Formalin) glue, which has its own floorboard which is not commercially available in some MDF plants (there is no market). It is producing the domestic MDF for production.

There is no example of using the MDF as a charcoal container and various products for storing liquids or foods.

The present invention has been made to solve the above-mentioned drawbacks, and the object of the present invention is to produce charcoal by molding a variety of products and containers for storing various foods after shaping it into charcoal using MDF. .

An object of the present invention is to provide a strength to be used in everyday life after the manufacture of the processed article molded in MDF charcoal intact as it is.

The present invention is to provide a product made of charcoal functions such as far-infrared radiation function, anion release function, anti-corruption and deodorization function of the charcoal.

By using a conventional MDF produced and sold in the market to form a molding to have a certain size and shape, and to produce a charcoal to preserve the original shape in a vacuum state by eliminating the natural drying process such as solid wood.

The molding produces charcoal that is preserved intact through various furnaces capable of vacuum, such as molding furnaces or electric furnaces.

When the molding is processed and forced to dry, the inner space is made into a vacuum while being heated by means of a heating mechanism and a heating wire by placing them on the molding pedestal installed inside the drying furnace so as not to touch each other.

Starting at room temperature, the drying process is performed for 15 to 30 hours at a temperature of 120 to 180 ℃ in a vacuum.

After the drying process is carried out for about 4 hours at a temperature of 200 ~ 280 ℃ to remove the moisture contained in the organic material is to remove all moisture except the chemical moisture.

Now only chemical moisture remains, so it is heated to 250-800 ℃ for 6-10 hours to completely discharge the organic matter and allow it to dry completely.

Wood liquor generated during the drying process is discharged to the outside using a vacuum pump.

In addition, as the wood vinegar is discharged during the drying process, the volume of the molded product is reduced by 20 to 25%, and is made of charcoal which is preserved as it is.

Thus, the molded article made of charcoal is manufactured from charcoal in a state where the volume of the molded article is changed from a solid wood processed product state.

If the molded product is not used as it is, the temperature is continuously raised to 800 to 1250 ° C., and the organic matter and free moisture are completely removed while being fired while being molded into charcoal, thereby increasing the strength to complete the molded product.

In the firing process, when MDF is relatively strong, the strength is enough to be used in daily life even under 1000 ℃, but when MDF is relatively weak, it is necessary to raise the temperature to about 1250 ℃ by raising the temperature slightly above 100 ℃. Strength is provided.

At this time, as the temperature is increased, the strength is improved, but there is a disadvantage in that the function of the char is lowered.

The back (10, 20, 30) of the present invention is a wire (15) is connected to the fixed plate 14 and the body 13 and the frame 11 is fixed to the ceiling to form a char.

The body 13 is formed by stacking a plurality of plates formed of charcoal to overlap each other and forming a frame 11 so that the transparent portion 12 can be installed on the lower side thereof, and the socket 15 to which the wire 15 is connected ( 17 is fixed to the bulb 16 is assembled.

The back 20 shows another embodiment of the back 10, the back 30 so that the char plate 31 connected to the lower side of the body 33 is connected to the slope and the space 32 is formed in the center And inside the groove 34 is formed to be able to be molded into a variety of shapes.

In addition, as shown in FIG. 10, the rod 42 is connected to the outside of the mounting table 41, and then the connecting rod 43 is connected to the rod 42 to install a plurality of the backs 10 on the lower side thereof. Etc. 40 may be provided.

Body 13 and 33 and the frame 11 and the charcoal plate 31 is completed only by the process of forming the finishing process by shaping the container of the pre-processed state using charcoal.

In addition, it is a one-piece charcoal molded, or given a certain strength is not easily broken when used, it can be used for a long time.

The lamp 10 has been described in one embodiment, and as shown in FIG. 10, the decorative rod 52 can be applied to the stand 50 and the upper side of the pedestal 51 in which the switch 58 is installed. And a metal connector 53 is formed at a portion of the decorative rod 52 to connect the bulb cover 56, and a socket 54 is installed inside the bulb 55 to fit the bulb cover 56 at the same time. There are a plurality of through-holes 57 are formed, so that the bulb cover 56 formed of charcoal by the light of the bulb 55 generates a lot of far infrared rays can be used as the stand 50 at the same time.

Although the above has been described with respect to the back (10, 20, 30) and the stand 50, the product can be molded into a bowl (dish, bowl, etc.) that can store food, can be processed in various ways depending on the required use It is.

According to the accompanying drawings, preferred embodiments of the present invention having such a configuration will be described in detail.
