Detailed description of the silver and silver nano (20) which is a constituent of the present invention in order to help understanding of the present invention is as follows.

    Nanotechnology is a technology that identifies and controls substances at the molecular and atomic levels.It comes from the Greek word dwarf, lanose, and 1 nanometer 'corresponds to one-tenth of the thickness of the hair. It is made of silver solution (colloid), which is a chemical decomposition method or a fine particle state in nano units, and is widely used in industrial fields.

Silver, the main ingredient of Nano silver, has been recognized as a precious metal of high value from ancient times, and has been the object of collection, and it is recognized as an important industrial material in modern industry as well as its value as money. The production of silver is proportional to the production of gold in many ways.

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, melting point 380 is 960.5 ℃.

In particular, the melting point (380) of silver is very important for the temperature compensation of high thermometers, and it is the standard of scientific and industrial temperature. Silver is the best conductor of metal, and is widely used for mechanical contacts and other electronics. .

Silver is optically 90% of visible light, which is one of the most excellent metals like platinum. Pure silver does not rust even when left in the air or heated (290), but it reacts with sulfur and hydrogen sulfide to emulsify it. Silver is made and turns black.

     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 strength of the cast was up to about 29 kgf / mm 2, the combustion rate was 48 to 54%, and the recrystallization temperature was 150 ° C.

    Particularly, in the case of pure silver, the processed hardened material is softened by recrystallization at normal room temperature (250), and the malleability and flexibility are rich after gold, so that the thin silver plate of silver foil can be spread to a thickness of 0.2 μm.

     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 (20) briefly described the silver nano (20) (Nano silver) extraction method and features in the present invention 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 (20) was first developed by a biotechnology company, a government-affiliated organization in our country, and was named silver nano (20) as a compound name of the brand name Na no-technology and silver. ;

  Silver nano (20) is a field of Na no-technology and is an advanced antimicrobial agent that utilizes silver's strong antibacterial and bactericidal function and excellent electrical conductivity mechanism. Silver nano (20) is unlikely to be resistant to bacteria, unlike conventional antibiotics. Silver nano (20) has been shown to kill almost all single cell germs on the ground in a short time. .

 Currently, a variety of products based on silver nano (20) consisting of powder and solution have been devised and produced in real life. This technology, called silver nano (20), uses silver nanometer (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 silver (Age) is a new concept that is made by using excellent effects such as anti-bacterial, deodorizing power, and extended food preservation time among many characteristics of silver. .

 Since ancient times, silver has been recognized as a disinfecting material that not only prevents bacteria but also East and West. Currently, the extraction method of silver (20) (Age 99.9%) is added to distilled water. It generates low current at low temperature, electrolyzes compounds containing silver, and conducts electrophoresis using + and-poles of each molecule to collect silver (Age 99.9%). In addition, liquid reduction and grinding It can be manufactured by the physical method such as, and the electrolysis method is used a lot to obtain a stable silver nano (20) (Nano silver).

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%.

 The silver nano 20 of the present invention is an ultrafine particle of silver having a particle diameter of 0.01 to 300 nm, which directly acts on harmful bacteria, directly dissolves the cell membranes of harmful bacteria, and sterilizes by disrupting the electron transfer system of harmful bacteria. It has antibacterial and antibacterial properties (99.9%) (reference virus size is about 10 nm).

     The main antimicrobial mechanism of silver nano (20) is to dissolve harmful bacteria cell membranes and interact with enzymes in the cells to block the metabolic function of nutrients, ie, the influx and discharge of nutrients, and to stop the respiratory function and production of harmful bacteria. And destroys regenerating ability to kill harmful bacteria.

     In addition, the silver nano (20) by controlling the harmful bacteria by releasing the antimicrobial power continuously from the fine particles is excellent in the antimicrobial, antimicrobial sustainability.

Therefore, silver nano (20) does not produce resistance and silver nano (20) is effective to perform a surface reaction and kill all the germs 99%, particularly effective in the general E. coli or food poisoning.

   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.

In silver nano (20) (Nano silver) is the best antibacterial silver nano particles (20) minimized.

   In addition, unlike the general chemical antibacterial or chlorine disinfectant, silver nano (20) is a pure silver ultra fine particle, has excellent antibacterial and bactericidal zone (99.9%) even at high temperature, non-toxic and non-irritating to the human body, bacteria and E. coli virus fungus It has been reported that bacteria cannot live in contact with silver nano 20 for more than 5 minutes.

As described above, the silver nano 20 material is added to a membrane film 10 made of a synthetic resin material, and then coated (400) or mixed (380) or woven (60). Functional antimicrobial membrane membrane (10) containing silver nano (20) to anti-sterilize and block attached bacteria and harmful substances, and to release healthy ions and far infrared rays;

(80) can be extruded (270) or weaving (60) by a weaving machine, and the silver nano (20) yarn (thread) made of silver nano (20) material at the time of weaving is a membrane film ( Based on 100% by weight of the total weight of the fiber, which is the material of 10), it is preferable that the silver nano 20 blends with the membrane film at 0.01 to 30% by weight so that the membrane film body is woven 60 or woven.

In addition, the particle size of the silver nano 20 is characterized by having a particle diameter of 0.01 to 300nm

In addition, it is also preferable that the secondary coating 400 of the body of the membrane membrane mixed with the silver nano 20 with the silver nano 20 to enhance the sterilization power of the membrane membrane 10 is completed.

On the other hand, look at in detail the molding manufacturing method of the membrane film 10 made of a synthetic resin, poly-based material according to the present invention for achieving the above object.

1, injection molding

 The molding material is heated (290) and melted (380) by injection molding into a cavity of a closed mold, and then solidified or cured to form a molded product. The molding method is suitable for mass production of complex shaped products. It is a field.

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

Molding is carried out as follows: ① body, ② injection, ③ holding pressure (this series of processes to prevent backflow of the material filled in the cavity and extract it by cooling is repeated as one cycle). The inline screw injection molding machine is a standard type of screw, which is retracted by the plasticization of the molding material, and when it is injected, the screw is advanced to extrude the molding material, and this type of molding machine is also used for molding the thermosetting resin.

Compared to the case of the thermoplastic resin, if the resin is cured by heating the molding, 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

 Thermoplastic plastic materials are put on the surface of various thin substrates such as paper, cloth, cellophane, plastic, film, metal film, etc., heated and melted by using an extruder to make a fluid state, and then extruded in a thin film form at the T band and continuously It is a pressing method. The combination of the properties of the substrate and the characteristics of the extruded and compressed thermoplastics (waterproof, moisture proof, refractory chemical properties, flexible toughness, breathability, heat seal synthesis, etc.) creates a packaging volume layer material that adapts to a variety of applications, but is currently practical. Mainstream products are 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 of the membrane film 10 introduced is put in a recessed groove (called a cavity) of a heated molding and press-molded by a compression molding machine (press).

 The molding material is heated in the cavity and once flowed, spreads to every corner of the cavity and causes a simultaneous chemical reaction to cure.Then, after a suitable time (called curing time), the molding is opened, the molded product is taken out, and then finished after flash removal. To get the product. If the molding process is largely divided into molding process and finishing process. The molding process is performed by ① molding material processing weight (in some cases, the turret machine may be used for the turret processing) ② loading of material into the cavity (preheated beforehand)

 ③ Pressurization operation (low pressure pressurization, gas 뺌 high pressure pressurization) ④ hardening process ⑤ ejecting molded parts It is cleaning of molding.

In the finishing process, there are ① flash 뗌 ② gloss, etc., and large-size or thick-walled moldings are usually preheated at high frequency for efficiency and quality improvement, and the curing time is determined according to the molding temperature or the thickness of the molded product. It should be decided properly. Thermoplastics also have compression molding in the production of thick products or in the production of small silicon films. In this case, the trick is to take out the molded article by cooling the molding after heating and pressing the molding material. In general, compression molding is characterized in that a molded article having less internal stress is easy to obtain because the orientation of dielectric materials and molecules is smaller than that of injection molding or transfer molding.

 3, extrusion-blow molding

Extrusion blow molding is carried out by inserting into one or two flies or two or more moldings continuously extruded into a tube from an extruder by heating and melting the plastic material injected into the tube, closing the top and bottom, and then blowing air into the fly hands from the mandrel. The fly hand is a blow molding method that is most popular at present in the method of making the membrane film 10 in close contact with the molding inner wall.

 4, blow molding

 It is a method of softening by heating in a split molding and blowing a fly hand or a sheet into which thermoplastics are put, using pneumatic pressure or the like, and cooling it simultaneously when it is in close contact with the molding to obtain an air body. This is called blow molding or blow molding.

Usually, a hollow product by extruding a hot-melted thermoplastic molding material or inserting a Parisian or two-sheeted sheet preformed into a tube according to an injection method into a blow molding mold, followed by heat softening, and blowing air therein. Mold.

There are various types of blow molding according to the state molding method of flyson, and typical examples thereof include injection blow molding, extrusion blow molding, sheet blow method (sheet flyson method), direct blow molding, and injection blow molding.

5, casting

 It is a molding method in which a liquid retaining resin solution or a compounded rubber latex liquid is introduced into an open type or cotton, and solidified by drying (360) or polymerization in commerce. In thermoset plastics, it is used as monomer, prepolymer or polymer solution in the initial condensate or in free polymer thermoplastics.

 6, vacuum forming

 After heating and softening the injected thermoplastic plastic sheet, it is placed on the mold, and the gap between the tongue and the sheet is vacuumed, the sheet is brought into close contact with the surface of the mold and cooled to fix the phenomenon of the molded article. Take out the molded product. If a female is used, it is called a straight forming, and if a male is used, it is called a draping forming.

In the above description, a preferred conventional molding method used in the manufacture of various membrane membranes 10 of the present application has been described, and the term containing the silver nano 20 of the present application using any one or more of the above preferred molding methods is described. Excellent membrane membrane with bactericidal power is born.
