 The silver and silver nano 160, which is a constituent of the present invention, will be described in detail as follows to help understanding.

     Silver, the main component of silver nano (160) (Na no silver), has been recognized as a precious metal of high value since ancient times, and has been the object of collection and has been spotlighted as an important industrial material in modern industry as well as its value as money. The production of silver is in many ways proportional to the production of gold.

Silver was mined early in Europe's Mediterranean coast, where silver was produced from the Incas and Aztecs before the discovery of the Americas, and then silver from Peru and Bolivia entered Europe and flowed out from 1520 to 1800.

It has grown steadily, but has declined since the discovery of large amounts of silver in the early 19th century.

Currently, the world's major silver producers are Russia (13.8%), Canada (13.5%), Mexico (13%), Peru (13%), United States (11%), Australia (8%), Poland (6%). The country's silver reserves are 17 million tons, and its mining capacity is about 1.2 million tons. As of 2002, silver produced in Korea is about 5,000 kg, which accounts for 1.2% of the total domestic demand. The amount is so small that the rest of the silver is imported from abroad.

Characteristics of silver: The color of silver is gray in the case of elegant gray-white metal or powder, specific gravity is 10-12, Mohs hardness is 2.5-3, and melting (80) point is 960.5 ℃.

In particular, the melting point of silver is very important for the temperature compensation of high thermometers, which is the standard of scientific and industrial temperature. Silver is the best conductor of metal and is used extensively for mechanical contacts and other electronics.

Silver is optically 90% of visible light, which is one of the best metals such as platinum, and silver does not rust even when left in the air or heated. However, silver reacts with sulfur and hydrogen to make emulsified silver. There is a changing nature.

     In addition, the mechanical properties change according to the amount of impurities (O₂) contained in the silver, and the hardness of the high-purity silver obtained by thermal annealing is Brinell hardness HBS (10/500) 25-27, tensile strength 12-16kgf / mm2. The cast material had a tensile strength of up to about 29 kgf / mm 2 and a recrystallization temperature of 150 ° C.

    In particular, in the case of pure silver, the processed hardened material is softened by recrystallization at normal room temperature and softened softly. The malleability and flexibility are rich after gold.

     The effect of silver has been used as a tool to check the imbalance of the body that one cannot feel because the gloss or color changes depending on the condition of the body when worn on the body from ancient times. This fatigue or low rhythm), Dongbobogam said that it is effective in the prevention and treatment of mental disorders and women's diseases such as epilepsy and game. The five chapters are said to be comfortable, the mind and body are stabilized, and the main body records that the body is lengthened by chasing morale and lightening the body.

      Also, when the Black Plague prevailed in the Middle Ages, nobility of the black aristocrats and royals, who had many silverware and silver utensils, did not have black plague, which released silver to the extent that it was able to sterilize the Black Plague bacteria, making it relatively safe from infectious diseases. In the place where the royal family and the state guests were served, silver products were used habitually.

In order to help the understanding of the silver nano 160, a brief description of the method and features of silver nano 160 (Na no silver) extraction in the present invention is as follows.

The atomic weight of silver is 107.87 amu and the fact that silver (Ag) is bactericidal has been known for a long time.

Silver Nano 160 was first developed by a biotechnology company, a government-affiliated organization in our country, and was named Silver Nano 160 as a compound name of the brand name Na no-technology and silver. ;

  Silver nano (160) is a field of Na no-technology (nano technology) is an advanced antimicrobial agent using the mechanism of strong antibacterial and sterilization function, electromagnetic shielding excellent electrical conductivity. Silver nano (160) (Na no silver) is unlikely to be resistant to bacteria unlike traditional antibiotics, and silver nano (160) has been confirmed to kill almost all single cell germs on the ground in a short time. It became.

 Currently, a variety of products based on silver nano 160 consisting of powder and solution have been invented and commercialized and produced in real life. This technology, called silver nano 160, is capable of converting silver to nanometers (1 billion won). It is a small particle size of 1m / min), that is, 0.000000001mm. When one gram of silver is aged, ten particles can be produced.

Therefore, silver nano (160) (Na no silver), which is aged in the form of ultra-fine particles of silver, is manufactured by utilizing the excellent efficacy of antibacterial ability, deodorizing power, and extended food preservation time among many characteristics of silver. It is a new concept.

 Since ancient times, silver has been recognized as a disinfecting substance that not only prevents bacteria but also East and West. Currently, the extraction method of silver nano (160) (Na no silver) is used to add silver (Age 99.9%) to distilled water. After generating low current at low temperature, electrolyzing compounds containing silver and conducting electrophoresis using + and-poles of each molecule, silver (Age 99.9%) can be collected. In addition, liquid reduction and grinding It can be manufactured by a physical method such as) and to obtain a stable silver nano (160) (Na no silver) the electrolysis method is used a lot.

Silver ions are also used in general sterilization concept machines and disinfectants, and all silver products currently used are silver obtained by decomposition, and the sterilization power of silver varies depending on the product, but can obtain up to 99%.

  Silver nano 160 is a fine particle of 1 ~ 5nm silver, which acts directly on harmful bacteria, directly dissolves harmful cell membranes, and sterilizes by disrupting the electron transfer system of harmful bacteria. 99.9%) (the virus size is about 10 nm).

     The main antibacterial mechanism of silver nano (160) is to dissolve harmful bacteria cell membranes and interact with enzymes in the cells to block the metabolic function of nutrients, that is, the influx and discharge of nutrients, and stop the respiration and production of harmful bacteria And destroys regenerating ability to kill harmful bacteria.

     In addition, since the silver nano 160 controls the harmful bacteria by releasing antimicrobial power continuously from the fine particles, the antimicrobial and bactericidal function is excellent in sustainability.

Therefore, silver nano (160) does not produce resistance and silver nano (160) has a surface reaction is effective and can kill all the germs 99%, especially in the common E. coli or food poisoning equality.

   The smaller the nanoparticles, the better the bactericidal and antimicrobial activity. Based on the experimental data so far, Escherichia coli, Staphylococcus aureus, Salmonella, Vibrio bacillus, Heterogeneous bacteria, Pneumococcus, Typhoid bacillus and the most resistant MRSA Resistant Staphylococcus aureus) can be 99.9% antibacterial and sterilized.

     Even if silver exists in an ionic state or a metal state, it can be referred to as colloidal silver if it exists in a colloidal state by a solvent.

Silver nano (160) (Na no silver) is also the best antibacterial silver nano (160) minimized the particles.

   In addition, unlike the general chemical antimicrobial agent or chlorine disinfectant, silver nano 160 is an ultrafine particle of pure silver. It is reported that the bacteria can not live in contact with the silver nano 160 for more than 5 minutes.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Method for producing a distribution plate of the present invention will follow a conventional method for producing a distribution plate and will be described in detail with reference to the accompanying drawings, a preferred embodiment of the present invention.

First, as shown in Figure 1, the plate of the present invention is composed of a side dish space portion that can put three to five side dishes, and a rice space portion that can put rice and a soup space portion that can put soup .

The main body 200 forms a space part that can hold three to five side dishes side by side on one side, thereby causing malodors and bacteria or food poisoning or acute enteritis caused by food waste on the plate. It is possible to prevent the source of the source to provide a clean, clean and sanitary dish plate.

2 to 3, the block diagram of the mixing (200) or molding process of the tray, made of plastic, synthetic resin and metal of the present invention

 As a block diagram of the process of mixing 200 of the plate containing the silver nano (160), the silver nano (160) solution or powder in the material of the plate, made of metal, synthetic resin, plastic, ceramic, silicon, acrylic, etc. To blending 200 or coating 180 at 20% by weight.

The material material of the tray is melted or melted (220), and then softened (360), and the silver nano (160) is added to the mixture (200), followed by stirring to form (340) and the module (380). After the 340, the slow cooling process is completed after the polishing process (480) and the cutting plate of the tray, which will be described in detail.

After removing this material in plastic or synthetic resin, it is put into the container 300, melted 220, and softened 360. Then, 0.1% to 5% by weight of a paint, a crosslinking agent and a hardening agent, and an adhesive are added to the material. 0.01 to 20% by weight of the silver nano 160 material to the total weight of the material, the size of the silver nano 160 has a particle size of 0.0 1 to 300nm and 0.1% of the curing agent or flocculant to promote curing To 5% by weight and the pigment in 0.1% to 5% by weight in order to give the color of the tray plate is put into the molded module 380 molded and injected or molded (340) and cooled and dried (260) process After the inspection, the steps of packaging and completion are shown as a block diagram illustrating the type and method of injection molding 340 as follows.

1, injection molding 340

 It is suitable for mass production of complex shaped products by the molding method of forming the molding plate 340 by heating and melting 220, injection-filling the cavity of the pre-closed mold, and then solidifying or curing to form a molded product. Molding 340 is a major field of processing.

 The molding materials used for injection molding are thermoplastic resins, which are mainly applied to almost all molding materials such as thermosetting resins, rubbers and foam molding materials, and various kinds of molding materials and mold structures have been developed in consideration of the types of molding materials. .

Molding is a standard type of line screw type injection molding machine which is ① mold, ② injection, ③ holding pressure (this series of processes to prevent backflow of material filled in cavity and extract by cooling is repeated as one cycle). When retreating and injecting by material digestion, the screw advances to extrude the molding material and the molding machine of this type is also used for molding the thermosetting resin.

Compared with the thermoplastic resin, when the mold is heated to cure the resin, the temperature of the heating cylinder is lowered to prevent the resin from solidifying, and thus, the heating method of the cylinder and the shape of the screw are somewhat different.

Next, as a method of determining the injection molding conditions;

1, extrusion

 After putting silver nano 160 into a thermoplastic material on the surface of various thin layer substrates such as paper, cloth, cellophane, plastic, vinyl, film, metal film, etc. It is a processing method which extrudes in thin film form from T band and simultaneously crimps continuously. Characteristics of the substrate and the thermoplastic plastic

Combinations of features (water resistance, moisture resistance, chemical resistance, flexibility toughness, breathability, heat rod synthesis, etc.) make the packaging volume layer material adaptable to various applications, but the mainstream of the current practical use is low density polyethylene, polypropylene, Vinylene chloride resin and the like.

2, compression-molding

 In the most common molding method of the thermosetting resin, the molding material into which the silver nano 160 is charged is placed in a pothole (called a cavity) of the heated mold, and the mold plate is press-molded by a compression molding machine (press).

 The molding material of the tray is heated in the cavity and once flowed, spreads to every corner of the cavity and causes a simultaneous chemical reaction to cure, so after opening the mold after a suitable time (called curing time) You can get the product by finishing, and if you divide the molding process largely, it will be the forming process and finishing process.

The molding process is carried out by ① molding material processing weighing (sometimes, it may be done by using a turret machine) and ② inserting material into the cavity (preheated before)

 ③ Pressurization operation (low pressure pressurization, high pressure pressurization) ④ Curing process ⑤ Remove molded product It is to clean the mold.

Finishing process includes ① flash 뗌 ② gloss, etc., and for molding large and thick products, high frequency preheating is usually performed for efficiency and quality improvement. It should be decided properly. In the case of molding a thick product even in a thermoplastic resin or producing a silicon film, compression molding is performed. In this case, the method is to remove the molded product by cooling the mold after heating and pressing the molding material. In general, the compression molding is characterized by less molding of the dielectric material or molecules compared to injection molding or transfer molding, so that a molded article having less internal stress can be easily obtained.

 3, extrusion-blow molding

 Plastic material or synthetic resin in which silver nano 160 is injected,

It is inserted into one or two or more molds of flies that are continuously melted and extruded into a tube from an extruder by heating and melting (220), and the top and bottom are sealed and then expanded by blowing air into the fly hands from the mandrel. It is a method of making a product of a distributing plate by being in close contact with the inner wall and is the most popular blow molding method.

 4, blow molding

 It is a method of softening 360 by heating in a split mold to inflate a flyson or sheet into which a thermoplastic or synthetic resin material and silver nano 160 are injected, by using air pressure, and simultaneously cooling the same to a mold to obtain an air body. . Blow molding or blow molding is usually carried out by extruding a thermoplastic molding material which has been hot-melted 220, or by inserting a Parisian or two-sheeted sheet pre-formed into a tube according to an injection method into a mold for blow molding 340. After heat softening (360), the air is blown into such a hollow product to be molded (340). There are various forms of blow molding according to the Parisian state molding method and the like, such as injection blow molding, extrusion blow molding, sheet blow method (sheet fly hand method), direct blow molding, blow molding and the like.

5, vacuum forming

 After heat softening (360) the thermoplastic material in which the silver nano (160) is injected, and put it on the mold, immediately after the gap between the tongue and the sheet is vacuumed to adhere to the surface of the mold and cooled to fix the phenomenon of the molded article, On the contrary, when the air is sucked out and the shaped part is used to take out the molded product, it is called a spun-forming foam forming and when the male type is used, it is called a drape forming.

6. vacuum deposition;

A brief overview of vacuum deposition refers to attaching the vapor to the surface of an object by heating a small piece of metal or nonmetal to which silver nano 160 is injected in a vacuum.

That is, a method in which a current is applied to a tungsten coil in which a metal (Al) or chromium (Cr) piece to be attached to the surface (object to be deposited) to be coated in a high vacuum state and a metal (Al) or chromium (Cr) piece to be attached to the surface is heated and attached in a high vacuum state. I use it.

In the vacuum deposition process, the paint used in BASE and TOP is composed of urethane acrylate, monomer, and other additives, and it can represent various types of products depending on whether the paint is glossy or matte.

In addition, dyes can be added during TOP PAINT spraying to represent any color desired.

As a result, the method for forming a mold 340 formed of a plastic plate, a synthetic resin, or a rubber material was described. In addition, a brief description of a general coating process 180 of the plate containing the silver nano 160 of the present invention will be given below. same.

Pre-treatment step to remove the material of the regular plate, the surface of the plate through the pre-treatment step coating the surface color and then drying (260) it coating (180) and coating 180 through the step The coating process 180 and the process of spray coating 180 by mixing (200) the paint and silver nano (160) material on the surface of the plate to go through the surface resistance coating (180) step to lower the surface resistance from the surface of the plate and this process After passing through a slow cooling process and drying (260) shows the step of completing the step.

Silver nano (160) is added to the entire material of the culture plate in a preferred weight ratio of 0.01 to 20% by weight, and other metals 20 to 99% by weight of stainless steel, 10 to 99% by weight of iron, 10 to 99% by weight of titanium Or commit. 0.01 to 10% by weight of gold or gold nano, 0.01 to 10% by weight of zinc, or 0.01 to 10% by weight of platinum or platinum nano may be prepared by feeding into a tray.

4 is a block diagram of the wet plating process of the functional dish plate of the present invention.

In order to coat the inside and the outside of the finished plate, the wet plating method of electroplating the silver nano 160 or a dry plating method using plasma may be used, and the present invention follows a conventional plating method. Since there are many types and methods of plating 180, and all of them cannot be listed, a preferred embodiment of the wet electroplating will be described.

 Coating 180 or plating is generally divided into electroplating 180 and electroless plating 180, and silver plating requires a solution containing silver ions, and gold plating requires a solution containing gold nano ions. I will.

 When the electrode is placed in a solution containing metal ions and a current is applied, metal ions are discharged and precipitated at the cathode, which is used to form a thin film of metal on the surface of the article placed on the cathode.

The purpose of plating 180 is to beautifully finish the appearance of the article, to increase corrosion resistance, to resist wear and corrosion, and to obtain other necessary surface properties. The purpose is to reduce the pain of the patient during the insertion and insertion of the germ board.

 The general sequence of the electroplating of the present invention is the plating of nickel as a preliminary plating process so that the metal plating of the metal plate of the galvanizing plate (500) and the second silver nano (160) plating 180 is coated well ( This process may be omitted if necessary, and finally, the silver nano 160 may be plated 180.

 The silver nano 160 is used as the cathode, and the metal to be electrodeposited is used as the anode. The silver nano 160 is immersed in an electrolyte containing nano silver ions to be electrodeposited. Will stick to the surface of the.

Looking at the process of plating (180) the nano plate 160 to the culture plate is subjected to the cleaning process 420 and rinsing process (440) to shake off impurities in the main body 10 of the finished culture plate and polished with abrasion (麻布) After passing through the step (460), it is washed with clean water and immersed in the plating solution.

In the plating tank 480, the plate is stored in a container containing the plate to be plated with silver nano 160 (Nano silver) and connected to the plate on the positive side, and the solidified silver nano on the pole side. Connect the plate 580, and inject the silver nano (160) solution 160 containing the silver nano (160) ions and flow a direct-current electricity to the +,-pole and gradually the silver nano (160) ( Nano silver) to be coated (180) and coated (180) or plated (180) silver nano (160) (Nano silver) plate once again washing process (420) and drying (260) process (260) After going through and drying (260) is to be completed and packaged.

As described above, the negative electrode of the battery is attached to the object to be plated (180), and the positive electrode of the silver nano (160) plate 580 is attached to the cation and anion of the silver, where the electron goes to the negative electrode plate. Of course, the aqueous solution contains silver nano (160) (Nano silver) ions-When the electrons come to the pole, the silver nano (160) (Nano silver) ions in the aqueous solution is attached to the plate around the plate and thus the distribution plate and reproduction The plate is nano 160 wet plating 180.

 The coating 180 of the silver nano 160 wet plating 180 is coated with a thickness of 0.0l μm to 50 μm (micrometer), and the weight of the coating plate is 0.01 to the whole of the plate. To 20% by weight and the particle size of the silver nano 160 has a particle size of 0.1 to 300nm and PPM content of 0.01 to 20PPM of silver nano 160 per 100 g to the weight of the culture plate in units of PPM. To be plated by rain.

In addition, the embodiment of the silver nano 160 plating 180 has the characteristics of the present invention because it follows the conventional plating 180 method and used the plating 180 material as the aged silver nano 160 material. will be.

Next, Figure 5 is a block diagram of the plasma coating process of the dry plating of the functional plate of the present invention as a block diagram of the plasma coating 180 process of dry plating of the culture plate containing the silver nano 160 of the present invention Plasma of the plate (plasma) and the coating 180 is described in detail as follows.

Plasma is a gaseous state that is separated into electrons with positive charges and positively charged ions at high temperatures, and has a high degree of charge separation but is neutral because of the same number of positive and positive charges.

 Since the long-acting Coulomb force acts between charges, it is characterized by the collective action of the whole moving under the influence of the distant state rather than the local state of the short distance. In 1928, I. Langmuer, USA, first applied the concept of plasma to ionized gases produced during electrical discharges.

  Plasma is derived from the Greek words πλσμα, -ατos, τ, and its original meaning is that it is built and assembled, and as the characteristics of group behavior suggest, it actually deals with plasma. There is a view that Plasma itself is usually behaving arbitrarily rather than easily controlled from the outside, and that the original name is wrong.So, Plasma is the fourth to be followed by solid, liquid, and gas (three states of matter). It is called material state.

As the temperature gradually increases, almost all objects change from solid to liquid and gaseous state, and at tens of thousands of degrees Celsius, the gas is separated into electrons and nuclei and becomes plasma.

Plasma is not common in everyday life, but it is common throughout the universe, because 99% of the universe is assumed to be plasma, for example conducting gases, rockets or lightning that carry currents in fluorescent lamps. There are ionized gases mixed in the gas when it hits, aurora borealis in the Arctic, ionosphere in the atmosphere.

 Plasma is present in the van allenic zone, solar winds intermittently pouring from the sun, and the hydrogen gas filling the space between the stars and surrounding gas and the stars is in the plasma state. to be.

Each object that makes up the plasma is electric, so it is very different from the neutral gas, has a high electrical conductivity, and the current is limited to the surface like a metal conductor. When applied, it is easily affected by the force as a charge, but as the charge density increases, the group movement differs from the individual movement, and the self-closing required by nuclear fusion means that the charge follows the magnetic field line. It is used to confine the Plasma to it by properly deforming the magnetic force line and confining it to a place in space.

 In the past, plasma research has been conducted in geophysics and astrophysics related to plasma around the earth and celestial bodies, but recently, the development of electromagnetic fluid dynamics (MHD) using the electrical properties of plasma, ion engines of space travel rockets, Research is underway for nuclear fusion research, and it has been a long time since the Department of Plasma was established in the science and engineering fields of Korean universities.

 As such, the high temperature and active chemical properties of plasma can provide extreme environments that are difficult to obtain by conventional methods and can be used to give new physical and chemical properties different from the body by changing the properties of new materials, metals or polymer surfaces. there is,

Diamond, for example, is an important material not only for jewelry but also for industry because of its high hardness, thermal conductivity, refractive index, and large band gap. Artificial synthesis of diamond was developed by GE company in USA in the 1950s. Although a high temperature and high pressure method has been mainly used, it was found in the early 1980s that diamonds could be obtained in the form of a thin film from the methane gas plasma at low pressure in the USSR, and thus used for semiconductor device, tool coating (180) and optical component coating (180). In addition, new applications are being actively explored for acoustic devices.

In addition, the wear-resistant coating 180, the decorative coating 180 of the tool, it can be made by a dry method through a reactive ion plating or sputtering method used as a diffusion barrier at the contact when manufacturing a semiconductor device.

In addition, if the surface of the polymer is treated with nitrogen or oxygen plasma, it can give hydrophilicity or hydrophobicity to the surface of the polymer, or it can improve antistatic, dichroic, deep color, etc. When contacted with a plasma and biased, a nitride or carburized layer is formed on the surface to improve the hardness, wear resistance, and corrosion resistance of the metal.
