As the quality of life and the quality of life of modern people increase, various interests are being put in order to create a beautiful and healthy living environment. Various types of building materials or finishing materials have been developed and studied in accordance with this trend.

In general, wood used mainly in interior is treated with formalin for preservation, and there is a concern that residual harmful substances are released after construction. Wallpaper, which is most widely used for wall decoration, is also contained in raw materials in the manufacturing process of the wallpaper itself, or the chemicals used in the printing process remain, thereby acting as a source of indoor air after the construction.

The volatile organic compounds emitted from building materials or finishing materials accumulate indoors when the ventilation is inadequate, especially in winter, and cause various problems such as atopic dermatitis, asthma, and headache due to symptoms of so-called sick house syndrome .

In order to minimize the sick house syndrome, indoor ventilation facilities, use of air purifiers, and harmful gas abatement techniques using photocatalysts are being used. However, the effect is still not so good. In addition, when ventilation or air purifiers are used, additional facilities are needed or maintenance is costly, and the photocatalytic coating needs to solve more fundamental problems such as abolishing the function due to abrasion .

It is a natural paper with high natural affinity. It is made of mulberry bark and flea. Its fiber length is 10mm and it is long fiber, so it is not torn easily and it is not easily discolored. It has the functionality and elasticity to adjust the temperature and humidity naturally, and it has the feature to make the inside ventilation possible by the micro hole called the pore.

Korean Patent Laid-Open Publication No. 2006-42609 discloses a functional wallpaper containing an oriental medicinal herb, but it is produced by coating a composition containing herb medicine, inorganic powder and organic powder in wallpaper, In addition, the manufacturing process is also complicated because the coating must be performed several times on the existing wallpaper.

On the other hand, the shell is a shell of shellfish, and the shell which is presently occurring in Korea is used as a powder, a fungus, an antacid, a dried shell, a paint, a mordant and a fertilizer. Researches are being made on the use of oysters and shell shells as concrete fine aggregates in the field of construction.

Despite this consumption, however, shells are treated as waste more than 400,000 tons per year, resulting in a large maintenance cost for landfill or landfill, and since shell processing methods are not widely available, , It causes not only bad odor due to being left unattended but also a serious environmental problem due to the fact that the shell ratio is about 70% as a main pollutant source of marine waste and recycling of shell is desperately required as a solution to such a problem It is a situation.

The shell is very fine and varied in color when crushed according to the type of shell, and has a considerable heat insulation performance due to the biochemically formed porous calcium component. It is known as a hygienic and eco-friendly material that has the ability to adsorb pollutants and the like.

On the other hand, a mineral is a general term of an element existing in a natural mineral, and the mineral originates from minerals such as pozzolan, sericite, tourmaline and heavenly earth. The above-mentioned minerals are mainly known to emit far infrared rays and a large amount of anions. They are effective for decontamination such as decomposition of formaldehyde, and have a beneficial function for daily living pollution such as prevention of corruption due to inhibition of fungi .

In recent years, there is a growing demand for Korean paper as architectural or industrial use. Accordingly, there is a need to develop and study a Korean paper tile having excellent color and texture by adding functionalities. However, a method for producing a tile in which a mulberry bast fiber, a shell, and a mineral are fused has not yet been disclosed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which a method of manufacturing a tile using a fiber, a shell and a mineral according to the present invention will be described in detail.

1. Raw material collection step

The raw material collection step is a step of collecting the mulberry tree and the shell, which are raw materials of the tile using the mulberry fiber, the shell and the mineral.

Cut the stem of the collected mackerel into a cutting machine, cut it into 50 ~ 70cm size, put it in a cauldron, boil it for 1-3 hours, and prepare the mackerel bark fiber so that the bark of the mackerel can be easily separated. At this time, it is preferable to use the mackerel cut from November to February between 1 November and 2 February. If you put the mackerel between November and February, it will contain proper moisture. It is because of softness.

The paper mulberry is also called low mulberry. It is originated in Asia and its height is 3m. Short hairs on small branches but soon disappear. The bark is grayish brown, the leaves are shifted, the length is 5 ~ 20cm, the edge of the leaf has sawtooth, and 2 ~ 3 pieces are deeply deflected. The front side is rough and the back side has short hairs but disappears soon. The petiole is 1 ~ 2cm and it has curly hairs, but gradually disappears. The fruit is a nucleus and it is round and ripens in red light from June to July. Especially in oriental medicine, berries are used for treatment of shortage of ovaries and various kinds of herbs. Young leaves are edible. In addition, mackerel has been mainly used in Korean paper, paper money, Korean paper, Korean paperboard, and wind-resistant paper since the Three Kingdoms period using bark (tree bark). The woody part has been used as compost after crushing. Fiber from mulberry trees has traditionally been used primarily in the manufacture of Korean paper.

Collect the shellfish collected from the coast, collect the contents, collect the discarded shells and prepare them. At this time, the type of the shell may include shellfish such as oysters, shellfish, abalone, seashells, cockleshells, foxtail shells, mussels, tall shellfishes and mussels.

2. Manufacturing process

The dough fiber production step is a step of producing the dough fiber from the dough produced by removing the black skin of the mulberry bark fiber.

The bark is harvested through the process of dough ignoring to remove the bark of the well-boiled mackerel. The bark is removed again after the dough process and dried in the sun to make the bark. The bark is washed in cold water for 1 to 2 days After boiling, boil ashes or buckwheat stalks in hot water, boil them in the lye, wash them, pick the teas, put them on the stone plate, beat them with a bat, and soak up the fiber structure of the mulberry tree. .

3. Preparation of shell powder

The shell powder preparation step is a step of preparing shell powder by washing, heating and crushing the collected shell shell.

The collected shell is washed with clean water so that salinity on the shell surface can be sufficiently removed. The primary washing is the work to remove vines and other seaweeds from the aquaculture process, and the secondary washing is a high pressure washing that is performed to remove contaminants that have not yet been treated in microorganisms and primary washing. The purpose of this washing process is to make the washing process of the shell from 1st to 2nd stage to remove the remaining salt in the collected shell, as well as to remove various foreign substances such as sand and mud in the inside to make it safe and hygienic. It is because.

The washed shell is heated at a high temperature of 900 DEG C so that it can be fired, the entire disinfection effect on the inside and outside of the shell is enhanced, and the microorganisms are sterilized. If the heating temperature is lower than 900 ° C, the effect of the shell on microbial sterilization and the efficiency of the crushing operation are lowered. If the heating temperature is 900 ° C or higher, Which is not effective.

Perform the first firing process at 900 ℃ for more than 1 hour and then the second firing process for more than 30 minutes. The reason for carrying out the first and second firing steps is to completely remove the microorganisms and foreign substances attached to the shell, and it is also possible to shorten the working time by facilitating the crushing even in the crushing process, Because it has the purpose of obtaining fine particles.

The heated shell is transferred to the crushing facility shell crusher.

In the first crushing process, the crust of the actual size is crushed into a plurality of crushed pieces. Next, in the crushing process, the crushed crust is crushed again and crushed, The powder is filtered in the form of a fine powder of 30 to 800 mesh to produce fine shell powder.

On the other hand, as shown in FIG. 2, when the powdery fiber and the shell powder are fused, the following effects are obtained.

In the production of Hanji (ground paper) using the fiber and shell, the density of the clay powder acts as a filler between the fibers due to the degree of confinement of the fiber and the amount of filler added, which increases the density (20% increase) The density is closely related to the improvement of the physical properties (tensile strength, etc.) of the final product, the elasticity is improved due to the constant relationship with the density, the shell powder acts as a filler, the smoothness is improved, whiteness and opacity are improved . In addition, the duck fiber product has little temperature dependency and high dependency on humidity. Since the shell powder acts as a filler, it imparts strong resistance to the liquid, so that the equilibrium moisture content due to suppression of liquid penetration can be maintained .

4. Raw material manufacturing stage

The raw material production step is a step of mixing raw material with the minerals comprising the shell fiber, shell powder, pozzolana, sericite, tourmaline and heaven soil.

15 to 20 parts by weight of shell powder, 20 to 25 parts by weight of pozzolan, 18 to 23 parts by weight of sericite, 15 to 25 parts by weight of tourmaline and 17 to 22 parts by weight of a ceiling soil were added to 100 parts by weight of the above- Mix for ~ 65 minutes.

At this time, the minerals consisting of the pozzolanic, sericite, tourmaline and celestial soot can be prepared in powder form as shown in FIG. 3 obtained by pulverizing in a pulverizer, followed by drying and heating.

More preferably, the pozzolan is pulverized to a mesh size of 325 mesh using a pulverizer to select particles. The particles are then dried in a drying chamber at 100 DEG C for one day so that the contained moisture can be removed, and then heated to 800 to 950 DEG C , And the sericite is pulverized by a grinder to a mesh size of 325 mesh to select particles. The particles are then dried in a drying chamber at 100 ° C. for one day to remove the contained moisture and then heated to 800 to 950 ° C. And the powder is prepared in powder form. The tourmaline is pulverized by a pulverizer to a mesh of 325 mesh to select particles. The powder is dried at 100 ° C for 1 day in a drying chamber so that the water contained therein can be removed, , And the ceiling soil is pulverized to a mesh of 325 mesh using a pulverizer to select particles, and then dried at 100 ° C for 1 day in a drying chamber to remove moisture contained therein And then heated to 800 to 950 ° C to prepare a powder.

The pozzolanic rock was first discovered in the town of Pozzolini in Italy, about 100 million years ago. It has been developed as a new advanced material not only in the advanced countries but also in Korea. It is known as a very useful minerals. Column is evaluated as the best. According to the literature, it is known that the pozzolan was used to make the buildings of the Colosseum arena in Rome, and it has been known as minerals with various substitution rates so far as there is no crack or corrosion.

This pozzolan contains a large amount of various organic matter and minerals, and has been known as a rock having high germanium content and high infrared emissivity and high heat effect.

The pozzolan has a characteristic of adsorbing an object such as a sponge with a porous rock, and a representative component of the pozzolan is germanium, the content of which is 2.0 ppm, which is 198 times larger than jade, and the effect of germanium, There is an excellent effect on emission and anion emission. Cations make bacteria and dust, pollen molds, and polluted particles float freely to make the air cloudy, while negative ions have the effect of neutralizing and eliminating them.

In addition, the pozzolan removes oxidizing substances in the body, activates skin cells by purifying blood as well as aging, promotes blood circulation, cleanses contaminated skin surface, and prevents Demo Dex In addition to antibacterial, antiseptic and deodorant, it is effective in preventing deterioration or discoloration due to its excellent water purification, detoxification and oxygen supply.

The sericite is a hydrated silicate mineral containing potassium and aluminum, which is rich in essential minerals and trace elements, and is also called sericite. This sericite is a representative mineral known to have a health-friendly action from ancient times to the east and west. It emits a large amount of anions and far infrared rays to activate cell activity, purify blood, relieve fatigue, relieve pain and increase immunity .

In particular, sericite has a strong anticancer substance called selenium, it is effective in prevention of various diseases, it is effective in preventing aging of skin, rich in various minerals, and is representative of the mountain in Korea. The sericite has a far-infrared effect, promotes blood circulation, facilitates metabolism, and has the efficacy of detoxification and detoxification. It has the effect of vibrating the cells by emitting the growth waves of the band similar to the human body. It is known to be effective.

Also, it is known that sericite has an effect of neutralizing or eliminating harmful substances in the air due to its antimicrobial and deodorizing effect, which is an effect of anion which smoothes and purifies the flow of blood flow.

The tourmaline is a minerals belonging to the hexagonal system having crystal structure such as crystal, and electricity is generated by friction, and it is effective for promoting the metabolism of the body by generating far infrared ray and anion. Moreover, it is known that tourmaline activates cell function and immune function, and is effective for blood circulation and purification with strong heat effect and high penetration.

Such tourmaline is effective for antioxidant activity, fatigue recovery, stimulation of blood circulation, stimulation of metabolism, blood pressure drop, blood purification, cell activation, anti-aging, etc. and is effective for stress relaxation, mental stabilization effect, autonomic control effect, facial effect, It is known to be effective in neurology and mental health.

In addition, it is known that it has a great effect on eliminating environmental pollution such as neutralization, odor removal, particulate removal, antibacterial and formaldehyde decomposition of a positive ion, decomposition of tobacco smoke, deodorization, preservation of food freshness, , Antistatic, etc. Anion is not only beneficial to the body but also has the effect of decomposing cations such as harmful chemicals, odors and electromagnetic waves in the atmosphere.

The celestial soot is a complex alkaline mineral mineral, also known as "天宝 药石", and belongs to feldspar porphyry among the igneous rocks. It is a natural stone which was used as a precious stone because it is non-toxic and has a special effect on skin diseases and traumatic treatments. It contains more than 45 kinds of mineral elements and is excellent in water quality improvement such as various minerals leaching, pH adjustment, It emits far-infrared rays with a high efficiency of more than 93% and is becoming an energy source to promote bio-growth and provide vitality. In addition, since the ore has been aged and evolved by the soil due to the volcanic and weathering processes for many years, the ore has been natural nanoized, and the porosity has been maximized and light, and various effects have been obtained in various fields by a large amount of anion and far- It is known as a mica-based natural clay mineral with warmth and beautiful color and fragrance.

These heavenly earths have amethyst seeds that increase the energy of man and have the effect of cutting off water and electromagnetic waves, and natural geomagnetism (neo-bium), which is the raw material of permanent magnets, .

In addition, it is known that heavenly soil contains zeolite with high odor removal efficiency and ingredients to reduce pain.

If the mixing time is shorter than 55 minutes, the surface of the prepared lipid can not be derived because the mackerel, the shell, and the particles of the mineral are not uniformly mixed with each other. Therefore, when the mixing time is longer than 65 minutes, It is desirable to comply with the above time because there is a reason that it is wasted and economically inefficient.

The beater is a machine that mixes pulp and other components to stir and hydrate the pulp to make the paper have the strength required for the raw material and spreads the fibers constituting the paper. When the beater is mixed with the beater, the beater can smoothly dissolve and dissolve So that the two materials can be mixed evenly without the bundling of the fiber and the shell and the mineral powder.

From the Hanji Art wall tiles to be produced by the above-mentioned minerals, it is possible to prevent the release of harmful substances such as formaldehyde and ammonia to enhance the functionality, and to prevent the generation and habit of bacteria and fungi, It has a great effect in preventing degeneration such as discoloration.

5. Background

The base paper manufacturing step is a step of preparing the raw materials, which have been mixed, through a paper making process as a base paper.

5 to 10 parts by weight of a dispersant may be added to 100 parts by weight of the raw material, and then the ground paper may be prepared by the conventionally-disclosed Korean paper manufacturing method.

Here, the above-mentioned dispersant may use a sulfur-containing slurry or PAM (chemical dispersant).

Hwangcheoggyu (黄 葵 葵) is an annual herbaceous plant belonging to the family Malvaceae is also called daphnia. Daphnia is planted for use as a papermaking sponge because it has many mucus in its roots. Hwangguk gyu is not only a medicinal herb but also contains a mucus component such as D-galactose, L-albino, L-rhamnose, xylose, glucose, D-galacturonic acid, aldobionic acid and tramalacturonic acid. It is also used as an important relief. It prevents the long fibers such as dirt bump from sinking by making the liquid of viscous fluid in the jets, adjusts the flow speed of water on the feet, and smoothes the lipid by facilitating the papermaking. In addition, it plays a role of helping the wetland piled up on the ground plate to fall off well when peeling off without squeezing it after squeezing.

On the other hand, a polyacryamide (PAM) chemical dispersant has properties similar to those of yellowing mucilage, and generally used as a pourable liquid is a viscous liquid or gel polymer having a viscosity of 40% or less and can be used by dissolving it in water .

As described above, when the sulfuric acid slurry or PAM is added in the Korean paper manufacturing process, the lipid of the background paper to be produced can be uniformized and a neutral pH (PH 7.5) material can be produced.

Among conventional methods of producing Korean paper, for example, the method of making the unicorn is a conventional method of papermaking, in which a foot is placed on a frame tied with one string and the former material and the next material are repeated. To control the thickness, two sheets of wetland are stacked in opposite directions to make one sheet of paper. As a result, the fibrous texture of the paper is crossed vertically and horizontally, so that a firm and durable paper can be manufactured. There is an effect that no tee is formed on the surface of the ground paper produced by the conventional papermaking method and that a uniform lipid can be derived.

6. Squeeze step

The pressing step is a step of placing the base paper on a mold and then pressing the paper in a hydraulic press.

The base paper is put into a mold and molded by applying a pressure of 3,000 kg in a hydraulic press at 70 to 80 ° C for 5 to 10 minutes. At this time, various patterns or patterns are formed on the inner circumferential surface of the mold so that a pattern or a pattern is formed on the surface of the ground which is pressed onto the mold.

The patterns and patterns are not limited to one, and various types of molds (planar and double-sided) can be manufactured and pressed.

On the other hand, the outer edge portion of the pressed sheet is cut by shaping so as to be clean.

7. Stage of painting

The coating step is a step of drying the press-formed base paper after drying, wherein the coating method is performed by applying a lacquer or a water-based finish material and drying.

The background is transferred to a drying chamber and dried at 40 DEG C for 60 to 90 minutes. In this case, if the drying time is less than 60 minutes, the entire surface of the substrate is not sufficiently dried, so that deformation of the finished product may occur and contaminants such as fungus may be generated. If the drying time is more than 90 minutes, It is effective to adhere to the above time because a phenomenon occurs or cracking may occur due to cracking phenomenon.

The dried base paper is subjected to finish coating in a space in which dust or foreign matter can not penetrate. As the coating method, either natural lacquer coating or water-based finish coating may be applied.

The natural lacquer finishing coating is applied by using the lacquer essence, and more specifically, it comprises a surface preparation process, a first coating process, a second coating process, and a third coating process as described below. In particular, the finish coat should be applied in a dry and clean condition to prevent contamination during application of dust and dirt.

As the first step of lacquer finish painting, the surface preparation process before application is to finely polish the rough surface of the background paper by finely sandpapering it before applying the lacquer essence.

The first coating is applied by thinning the coating so that the ruby lacquer can sufficiently penetrate into the base paper. The concentration of the first coating is 5 ~ 10g of pine oil based on 10g of fresh water.

After the pre-treatment, the temperature is 20 ~ 25 ℃ and the humidity is about 75 ~ 85%. At this time, the drying time may vary depending on the season. For example, in the summer rainy season, since the humidity becomes high, the drying time can be adjusted.

It is a translucent color that is filtered to use sticky milk (emulsion) that comes from the scarred marks on the skin of the lacquer trunk.

It is a colorless or pale yellow sticky liquid with a peculiar aroma, which is mainly used to make solvents and synthetic camphor.

Secondary application is a coating process which is applied by rubbing the surface of foundation paper with sandpaper and finishing the surface. It is applied repeatedly 4 to 5 times. 2 ~ 5g of pine seed oil is applied on the basis of 10g of fresh green on the basis of 10g of freshness, and then dried at 20 ~ 25 ℃ in the drying room for about 10 ~ 24 hours at a humidity of about 75 ~ 85%.

The third application is completed by applying 2 ~ 3 times repeatedly with the last whitening process. The concentration of the fillet is 0 ~ 2g of pine oil based on 10g of fresh water. And the humidity is about 75 ~ 85% for about 10 ~ 24 hours. After the pressing step, the finished tile can be manufactured through drying and lacquer finish painting.

The lacquer is an environmentally friendly paint harmless to human body extracted from lacquer tree. It is also used for medicinal and edible purposes. It has a beautiful gloss and does not change even when stored for a long time. It is very strong against acids and alkalis, . In addition, lacquer is an advanced painting material used in a variety of fields such as arts and crafts, furniture, dry lacquerware. The lacquer is a traditional painting technique that has been widely produced in some regions of East Asia such as Korea, China, Japan, and Taiwan. The lacquer has a good texture, and has a calm gloss and excellent transparency. In addition, lacquer has excellent antiseptic effect and disinfecting power and does not easily mold even after a long time, and also has excellent acid resistance, salt resistance, heat resistance, waterproofness, nonflammability and insulation effect. On the other hand, lacquer coating is effective for insecticide and waterproofing, and is effective for cleansing indoor air by reduction of acetaldehyde and toluene, improving atopy, and also for anticancer by the action of sterilizing power and antibacterial power.

Meanwhile, the water-based finishing material coating is performed by using a non-toxic water-based finishing material commercially available as a finishing material for Korean paper. More specifically, the surface finishing process, the first coating step, the second coating step, Lt; / RTI > In particular, the finish coat should be applied in a dry and clean condition to prevent contamination during application of dust and dirt.

As the first step of coating the water-based finish, the surface preparation process before application is to finely grind the rough surface of the background paper by finely sanding it before applying the water-based finish material.

The glutinous rice paste and water are mixed at a ratio of 1: 1 and diluted. The paste is applied 2 ~ 3 times and then dried in a drying chamber for 20 ~ The humidity is about 75 ~ 85% at 25 ℃ and it is dried for about 10 ~ 24 hours.

The second application is performed by applying the water-based finishing material 3 to 5 times, and then drying at 20 to 25 ° C in the drying chamber and about 75 to 85% for about 10 to 24 hours.

The third application is performed by applying the water-based finishing material 2 ~ 3 times and then drying at 20 ~ 25 ° C in the drying chamber for about 10 ~ 24 hours at a humidity of about 75 ~ 85%. After the pressing step, Tiles can be manufactured.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood by those skilled in the art that these examples are for illustrative purposes only and that the scope of the present invention is not construed as being limited by these examples.

Collecting the shellfish collected from the coast, collecting the contents, and collecting shells from the discarded shells were prepared.

The bark is extracted by removing the bark of the bark mulberry, and the bark is removed. After the barking process, the bark is removed and the bark is dried in the sun. The white papaya was soaked in cold water for one day and then boiled in a lye burned with cold beans and then washed. The tea was picked out, placed on a stone plate and kneaded with a bat, so that the mackerel fiber was loosened to prepare a mackerel.

The collected shell is washed with clean water to remove the shell of the shell. First, all the foreign substances on the surface of the shellfish shell shell were removed, and then the sand and the remnants remaining inside shell shell were removed by high pressure washing by the second order.

The shell having been cleaned is firstly sterilized by heating it at 900 DEG C for 1 hour or more at a high temperature to sterilize the microorganism. After heating for 1 hour or more, plastic deformation was further performed for 30 minutes in order to make the crushing easier.

The heated shell was transferred to a crushing facility and put into a shell crusher.

First, the shell of the actual size was crushed into a plurality of small pieces by the primary crushing process. The crushed small pieces of shell were put into crusher to prepare shell powder in the form of fine powder of 400 mesh.

The raw material is prepared by mixing the above-mentioned powder with a mineral such as shell powder, pozzolan, sericite, tourmaline and celestial soil, wherein the mineral is pulverized using a pulverizer, dried and heated. More preferably, the pozzolan is pulverized to a mesh size of 325 mesh using a pulverizer to select particles. The particles are then dried in a drying chamber at 100 DEG C for one day so that the contained moisture can be removed. And the sericite was pulverized by a grinder in a mesh of 325 mesh to select particles. The particles were then dried in a drying chamber at 100 ° C. for 10 days to remove the contained moisture, and then heated at 900 ° C. to form a powder And tourmaline was pulverized with a grinder in a mesh of 325 mesh to select particles. The particles were then dried in a drying chamber at 100 ° C for one day so that the contained water could be removed and then heated to 890 ° C to prepare powder The ground water was crushed to a mesh size of 325 mesh using a crusher to select particles. The particles were dried in a drying chamber at 100 ° C. for 1 day to remove moisture, and then dried at 920 ° C. And heated to produce powder.

20 parts by weight of shell powder, 19 parts by weight of pozzolan, 18 parts by weight of sericite, 20 parts by weight of tourmaline and 21 parts by weight of heavenly soil were put into a beater at 100 parts by weight for 100 minutes by weight.

8 parts by weight of the yellowing agent slurry was added to 100 parts by weight of the mixed raw materials, and then the feet were placed on a frame bound by a single string, and the ground material was prepared by a papermaking method in which the front and side materials were repeated.

The base paper is put into a mold and then pressed at 3,000 kg at 75 DEG C for 10 minutes in a hydraulic press so that a pattern is formed on the surface of the base paper. The outer edge of the ground finished with cutting was cut and cut.

The ground was transferred to a drying chamber and dried at 40 DEG C for 80 minutes. The dried surface was coated in a space where dust and the like could not penetrate.

In order to apply lacquer finish to the dried base paper, the rough surface of the base paper was trimmed by finely sandpapering before applying the lacquer essence.

And 8 g of rice bran oil was prepared on the basis of 10 g of fresh juice. The mixture was applied to the base paper in such a manner that the ruby lacquer was sufficiently permeated, and then applied to the drying chamber after the first coating. 80% &lt; / RTI &gt; for 24 hours.

The second application was carried out by repeating the application 4 times on the basis of 4 grams of the vegetable oil based on 10g of the fresh juice, and then transferred to the drying chamber after the secondary application, and dried at 25 ° C for about 22 hours at a humidity of 85%.

The third application was carried out by repeating the application of 1 g of fresh vegetable oil on the basis of 10 g of fresh vegetable and repeating it twice on the background paper. After the soaking process of the third application, it was transferred to the drying room and dried at 20 캜 and 75% Tiles with shells and minerals were prepared.
