Description

[Technical Field]

[0001] The present invention relates to an ozone gas ejection toothbrush device. [Background technology]

[0002] The use of ozone O3 has a strong bactericidal effect due to the combination of O3-O2+O↑, and in recent years, it has begun to be experimented with in many dental hospitals. For example, when using O3 in toothbrushes, O3 gas does not dissolve easily in water, but there is a water pick made with O3 water. This is said to have a periodontal bactericidal effect and reduce the number of caries-causing bacteria in saliva, such as Mudans and Lactobacillus, by injecting O3 water with a concentration of 100-200 ppm from a fine nozzle into the spaces between the teeth and gums and into periodontal pockets 1-4 mm deep. However, the O3 concentration of 100 to 200 ppm when the water is poured into the mouth decreases to 1 to 2 ppm within a short time after the water is poured, so the sterilizing effect of the O3 water on periodontal bacteria and caries bacteria in saliva is greatly reduced.

[0003] On the other hand, there are ultrasonic toothbrushes available on the market that operate at 18,000 cycles. However, while brushing your teeth for 3 to 5 minutes with an ultrasonic toothbrush can have some effect in scraping out periodontal disease bacteria from plaque, it does not have a sterilizing effect.

[0004] <About periodontal disease> Data shows that 70% of the Japanese population suffers from periodontal disease, while only 6.9% are healthy, and 25% are missing at least 20 teeth. Periodontal disease is a bacterial infection in which periodontal bacteria in interdental plaque cause inflammation in the gums and gradually destroy the surrounding tissue. It is also known as the silent daisy disease because it progresses without any noticeable symptoms such as pain. As the symptoms progress, it dissolves the bone that supports the teeth (alveolar bone), eventually causing tooth loss. It is important to know how important it is to brush your teeth thoroughly throughout your mouth.

[0005] <Reference information> The distinctive feature of ozone therapy is that it is painless, and no need to drill cavities or other tooth decay; instead, the therapist holds their breath for 10 to 20 seconds and a strong ozone gas of up to 200 ppm is sprayed. All you need to do is use an ultrasonic toothbrush that emits 0.01 to 0.05 ppm of ozone gas every day. For individuals, all you need to do is hold your breath after brushing your teeth and spray about 20 ppm of ozone into your mouth. Start with 5 ppm for the first time.

[0006] It is impossible to completely eliminate bacteria in the mouth. The human body has good bacteria, bad bacteria, and opportunistic bacteria in the mouth and in the stomach. Even with strong ozone, it is impossible to remove all bacteria and make the mouth sterile. Even with weak ozone (0.01-0.05 ppm), brushing your teeth 4-5 times a day is effective enough. By staying well hydrated and producing saliva, you can clean your mouth. This is due to the bactericidal effect of saliva.

[0007] In order to increase the number of good bacteria in your mouth and maintain the best oral flora, it is important to have dental care to remove plaque once or twice a year, and the basic principle is to brush your teeth. Our 0.01-0.05 ppm toothpaste reduces the number of times you visit the dentist for cleaning. It is said that the mouth is home to an estimated 10 billion bacteria, including "good bacteria," "bad bacteria," and "opportunistic bacteria." When the balance of oral flora is disrupted, bad bacteria increase, causing bad breath and increasing the risk of tooth decay and periodontal disease. The balance between good and bad bacteria is said to be 9:1. The basic principle is to brush your teeth thoroughly. It goes without saying that saliva is produced constantly while eating. Chewing gum outside of meals can help increase saliva production.

[0008] The surprising relationship between the intestines and saliva is that both improve intestinal immunity and the quality of saliva. "Intestinal immunity" and "oral salivary glands" are linked. Therefore, if intestinal immunity is strong, you will have a constitution that is less susceptible to colds, influenza, pneumonia, etc. This is because when the "quantity" of saliva increases, it has a strong function of cleansing the mouth. The amount of saliva secreted decreases with age. The mouth becomes more prone to dryness, which leads to the proliferation of bacteria and causes bad breath. Always stay hydrated. Saliva is active 24 hours a day, 365 days a year, without a break. It keeps the mouth clean, washes away food particles and bacteria, and has a self-cleaning effect on the mouth, so a decrease in saliva can lead to periodontal disease.

[0009] It goes without saying that saliva is present in the mouth, but we don't know much about how it is produced. Blood is produced in the bone marrow, and that blood is converted into saliva in the salivary glands, producing 1 to 1.5 liters per day. It is produced in large amounts during meals and decreases when you go to bed, so it is important to brush your teeth thoroughly before going to bed. A person has 32 teeth, including wisdom teeth, but many people have four extracted, so how difficult was it to keep 20 of the 28 teeth by the age of 80? Since we grew up using toothbrushes and toothpaste to simply brush our teeth, the best option left is implants, but they are not covered by insurance and are very expensive.

[0010] Periodontal plaque is not food debris, but a mass of bacteria, and it is said that there are about 1 billion bacteria in 1 mg of periodontal plaque. Plaque is a home for cavity-causing bacteria and periodontal disease bacteria. Once plaque has been circulated, it cannot be removed by brushing your teeth, but it can be removed by visiting a dentist. Our 0.01 to 0.05 ppm ozone becomes a weak alkali in the mouth, generating oxygen from the generator O3 → O2 + O↑. When fluoride reacts with saliva in the mouth, H2O → (OH) + H↑ is produced, which dissolves the bacteria in plaque. Therefore, brushing your teeth for 3 to 5 minutes, about 5 times a day, also has a bleaching effect, making your body less susceptible to plaque buildup. The bactericidal power of fluoride (OH) is stronger than that of ozone.

[0011] Periodontal disease bacteria are oxygen-hating bacteria (anaerobic bacteria), and the periodontal pockets are ideal pockets because oxygen is difficult to enter. They settle in the pockets, forming clumps and eventually becoming entrenched, leading to periodontal disease. These periodontal disease bacteria release toxins that completely block the good bacteria, allowing them to become the sole cause of periodontal disease and worsen. The bacteria that are attracting attention are the masterminds behind the proliferation of periodontal disease bacteria (Fn bacteria).Fn bacteria live in all parts of our body, including our saliva, periodontal plaque, and mucous membranes such as the tongue and oral cavity.

[0013] As mentioned above, when using O3 gas in toothbrushes, although O3 gas has strong bactericidal properties, it decomposes into O2 + O↑ in a short time. Therefore, if the concentration and amount can be controlled appropriately, it is thought that the bactericidal properties can be maintained for a long time, which would be a great therapeutic effect for periodontal disease. However, to make this a reality, it is necessary to develop a simple O3 generator and toothbrush that can generate trace concentrations of O3 and delay the decomposition time for a long period of time. Ozone therapy is a treatment that kills cavity-causing bacteria and periodontal disease bacteria and improves the balance with the normal bacteria in the oral cavity due to the high bactericidal power of ozone, which is said to be seven times stronger than chlorine. However, there are currently no toothbrushes that can directly emit precisely controlled O3 at 0.01 to 0.05 ppm. The present invention provides an ozone gas ejection toothbrush device that solves this problem by combining a simple low-concentration O3 generator with an O3 ejection toothbrush. [Means for solving the problem]

[0014] The technical feature of the present invention that solves the above problems is as described in the following item (1). (1) An ozone gas ejection toothbrush device characterized by comprising an ozone generator having a quartz pipe with a vapor deposition coating of two metals, Cr+W or Ti+W or Cr+Mo or Ti+Mo, on the surface and / or inside of the quartz pipe, and further coated with CuB by fusion baking, an ozone generator having a quartz pipe-type discharge tube with an ejector 203 on the air intake side of the quartz pipe and a magnet placement chamber for a neodymium magnet 204 on the outlet side, and an ultrasonic toothbrush having an ultrasonic vibrator built in the neck of the toothbrush, which introduces ozone gas from the ozone generator into the toothbrush and ejects it from an ejection hole provided in the head of the toothbrush. [Effects of the Invention]

[0015] Even if you use dental rinses and periodontal brushes to prevent the buildup of periodontal plaque, and even if you use fluoride-containing toothpaste, it is extremely difficult to remove 100% of the bacteria in plaque. It is difficult for ozone to penetrate 100% into the 0.1-0.5% gap between the gums that support the teeth. The oxygen radical generated when O3 decomposes to O2 + O acts as both a bleaching agent and a sterilizer. Furthermore, the strong vibration of 18,000 Hz allows the emulsified ozone to penetrate deeply. This type of effect has never been seen before. There are toothbrushes that produce hydrogen gas (He) by decomposing water, but they claim to produce (OH) and cannot be used to create an emulsion manually. We use an 18,000 Hz ultrasonic toothbrush to emit 0.01-0.05 ppm ozone gas, which is then used to create an emulsion with saliva.

[0016] O3 ozone, which is mainly produced at a concentration of 0.01 to 0.02 to 0.03 ppm, has been successfully tested many times using an ultra-tight high-frequency circuit design and a 0.01A to 0.03A double fuse-like resistor. Although it is simple, the 0.01A current cuts off in an instant. It is impossible to provide a backup if the device is in operation. For a maximum of 800 ppm, a maximum resistance of 10 Ω is required. Designing the circuit to account for this difference was difficult, but this invention is the first to successfully generate an optimally effective low concentration of ozone within Japanese regulations.

[0017] The ozone gas ejection toothbrush device of the present invention uses the ozone generator to generate an appropriate amount of O3 at a trace concentration and supply it to the ultrasonic toothbrush, thereby maintaining its bactericidal power for a long period of time and providing a significant therapeutic effect for periodontal disease.In other words, this ozone gas ejection toothbrush device combines a simple device that can generate O3 at a trace concentration and delay its decomposition time for a long period of time with a simple O3 ejection toothbrush.

[0018] That is, the ozone gas-ejecting toothbrush device of the present invention continuously supplies O3 gas at a concentration of 0.01 to 0.05 ppm from the ultrasonic toothbrush described above into the mouth while brushing teeth, causing the saliva in the mouth to become emulsified and delaying the decomposition of O3. This provides a more significant bactericidal effect than periodontal irrigation with the aforementioned O3 water. Furthermore, this ultrasonic toothbrush efficiently scrapes out periodontal disease-causing bacteria in plaque by spraying O3 gas at 0.01 to 0.05 ppm, thereby effectively preventing the onset of periodontal disease.

[Figure 4] FIG. 2 is a detailed overall cross-sectional side view of the quartz pipe discharge tube of the ozone generator shown in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, an embodiment of the present invention will be described in detail with reference to FIGS. [Example]

[0021] 1 to 5, the ozone gas ejection toothbrush device comprises a known toothbrush body 100 and an ozone generator 300 that supplies O3 gas to the toothbrush body 100. In this example, the ozone gas ejection toothbrush device continuously supplies 0.01 to 0.05 ppm ozone gas directly from the ozone generator 300 into the 18,000-cycle vibration ultrasonic toothbrush body 100 for 3 to 5 minutes during toothbrushing time, causing the saliva in the mouth to become emulsified, delaying the decomposition of ozone, scraping out periodontal disease-causing bacteria in plaque while brushing, and efficiently sterilizing various bacteria in the mouth, thereby preventing periodontal disease. Furthermore, the ultrasonic vibration toothbrush 100 of this example not only sprays ozone gas at a concentration of 0.01 to 0.05 ppm onto the teeth and gums, but also gently applies ultrasonic vibrations to the teeth, thereby not damaging the gums and maintaining good oral health while sterilizing oral bacteria such as periodontal disease bacteria, thereby maintaining oral health for a long period of time.

[0022] Thus, the toothbrush body 100 introduces ozone gas from the O3 supply pipe of the ozone generator 300 through an O3 gas inlet socket 200 provided between the upper end of the handle portion 101 and the lower part of the neck cover 102, and the ozone gas is sprayed from a spray hole 106 provided between the bristles 105 of the head 104 or at the top of the neck cover 102 near thereto.

[0023] As shown in Figure 3, toothbrush body 100 has neck vibration core 103 integrally molded on the upper part of handle 101. Neck vibration core 103 is housed in neck cover 102 and has ultrasonic vibrator 106 built in. The neck cover 102 is detachably fitted and connected to the lower part of the neck vibration core 103 . This fitting connection is achieved by fitting projection 103-1 of neck vibration core 103 and receiving recess 102-1 at the bottom of neck cover 102 with toothbrush. 4(3) is connected between the lower end of the neck vibration core 103 and the lower end of the toothbrush-equipped neck cover 102. The O3 gas introduction socket 200 has a ring portion 201 to which a NiCr-plated receptacle 202 is connected by silver brazing. The O3 gas introduction socket 200 receives O3 gas by connecting an O3 gas supply pipe 301 of the receptacle 202 to an O3 gas introduction hole 203 of the receptacle 202, which then introduces the O3 gas into the toothbrush body 100. The O3 gas introduced into the toothbrush body 100 from the O3 gas introduction socket 200 flows through the 0.1 mm gap between the tapered surface of the neck vibration core 103 and the tapered inner surface of the toothbrush-attached neck cover 102, and is ejected from the nozzle 204 provided in the neck at the upper end of the toothbrush-attached neck cover 102, directly below the head 104. The ultrasonic vibrator 107 transmits ultrasonic vibrations of 18,000 cycles to the bristles 105 of the head 104 via the neck vibration core 103 and the neck cover 102 with the toothbrush, causing it to vibrate.

[0024] The ozone generation device 300 can change the amount of ozone generated to 0.01 to 0.05 ppm, 200 to 400 ppm, or 400 to 800 ppm according to the purpose. The legally required ozone gas concentration for the human body is 0.01 to 0.05 ppm, but the ozone generator 300 of this example meets this requirement. The feature of this ozone generator 300 is that it uses a quartz pipe discharge tube 307, and its main components, as shown in Figures 2 and 3, are a battery 301, a control panel / timer condition setter 302, a high frequency power supply 303, a control PC 304, an air pump 305, and the quartz pipe discharge tube 307. (For indoor use, a 100V selector switch is provided.)

[0025] As shown in Figure 5, the quartz pipe discharge tube 307 is a type that has a quartz pipe 308 (outer diameter 15 mm x inner diameter 13 mm x length 38 mm) inside which Cu is plated, and the outer tube is wrapped with Cu foil or a steel wall, and a Cu+P spring pipe 309 that is tightly attached to the inner wall of the quartz pipe 308, thereby extending the life of the high frequency power source 303 and continuously generating a large current that can break the insulation of air. Even if the speed is increased by the electromagnetic magnetizer 311 as a measure against thermal expansion of the air, by magnetizing O3, the level of 0.02 to 0.03 ppm is maintained outside the hose with an outer diameter of 6 mm, an inner diameter of 4 mm, and a maximum length of 10 m. The Cu-P spring pipe 309 has such a strong spring force that it is sometimes called Cu spring steel, and therefore fits 100% tightly inside the quartz pipe 308, allowing high frequency electricity to flow stably.

[0026] The quartz pipe discharge tube 307 has an ejector 306 installed at its air inlet, and the inlet air is increased by about 30% to cool the high voltage heating, increasing the amount of O3 generated. The outlet is connected to an electromagnetic magnetic field 311 with neodymium magnets 310 of a total of 9000 to 9800 G, and the decomposition of O3 is delayed by passing the air through it. As a result, the half-life of O3 is 16 hours, but the dilute ozone O3 of 0.01 to 0.02 PPM / h is strongly retained.

[0027] In the ejector 306, the air in the quartz pipe 308 is instantly destroyed by high temperature and pressure, and when electricity is applied, O3 is generated. However, in the conventional single pipe system, the pressure of the air that is instantly destroyed and expanded increases by more than 30%, so the ejector 306 system is used on the air intake side to cover the amount of air needed so that it can withstand this 30% expansion pressure. In addition, since the expansion pressure leads to an increase in speed, an electromagnetic magnetizer 311 with neodymium magnets 310 that catch the primary air is installed on the outlet side to suppress the decomposition of O3. The secondary chamber, the electromagnetic magnetic fan 311, is entirely surrounded by 9000G magnetic field lines, and since the half-life of O3 is short at 16 hours, the Japanese safety standard is to operate for 3-5 minutes and rest for 15-20 minutes, so that the decomposition of weak ozone O3 can be slowed down.

[0028] Furthermore, the quartz pipe discharge tube 307 is coated on the surface and / or inner surface of the quartz pipe 308 by vapor deposition with two metals, Cr+W, Ti+W, Cr+Mo, or Ti+Mo, by the API method, and further coated with CuB by fusion baking. This allows the ozone generator 300 to change the O3 concentration according to the purpose, using the control PC 304 to 0.01 to 0.05 ppm, 200 to 400 ppm, or 400 to 800 ppm. The legally required ozone gas concentration for the human body is 0.01 to 0.05 ppm, but since this level is exceeded, the ozone generator 300 can generate ozone at a concentration of 0.01 to 0.05 ppm, 200 to 400 ppm, or 400 to 800 ppm, depending on the purpose.

[0029] The Ozone Generator 300's ultra-precise meter, with a maximum of 3.5 ppm, could measure a minimum of 0.016 ppm of ultra-low ozone, which was a blessing, so I was able to experiment with it myself, especially inside my mouth. I personally tested it on four teeth with periodontal disease. As a result, I didn't have to extract any teeth in December of last year, and my remaining teeth are gradually becoming healthier. Ozone therapy has been around for 15 years in Sweden, Germany and Japan. Ozone generators with ultra-precise control are very expensive and difficult to implement. This was the reason why it could not be applied to individual tooth brushing.

[0030] It is said that a single tooth inherited from one's parents costs 2 million yen. Implant treatment is said to cost 450,000 yen ± 10% of the original cost. Retaining 20 teeth at age 80 cannot be achieved by brushing three to four times a day. It is necessary to visit the dentist once or twice a year to have plaque removed. The inventors have created a low-cost ozone generator that is now available for personal use.

[0031] The quartz pipe discharge tube 307 has its surface coated with AIP vacuum deposition and its inner surface coated with CuB using a glaze similar to enamel, so it is possible to refine ozone gas of various concentrations in the range from trace to a maximum of 800 ppm.

[0032] <About W and Mo AIP vacuum deposition on the surface of the quartz pipe 308 of the quartz pipe discharge tube 307> The surface of the quartz pipe 308 is vacuum-deposited with AIP to form W and Mo particles of up to 6% roughness, which generates large, medium and small electrical discharges, making it possible to control the O3 concentration from 0.01 ppm to 800 ppm. AIP vacuum hardening coatings are primarily made to create hardened layers using ion particles in N2 gas, and up until now, TiN, TiAlN, TiCN, CrN, and ZrCrN have been used as coating targets. In a 100% Cr target, 6.3% of W ions in an area ratio were simultaneously ionized to form two types of ions, approximately 94% Cr and 6% W, and then deposited on a quartz pipe. This was the subject of an experiment in which a new target of these two ion metals was created. Due to arc discharge, the arc spot has a diameter of about 10 μm. 6 ~10 8 A / cm 2 This concentrates a high density current of up to 10000kJ, generating high Joule heat temperatures of 4000-10000kJ, which instantly melts and vaporizes the cathode material, making it relatively easy to vaporize refractory metals such as W (tungsten: 5555°C) and Mo (molybdenum: 4639°C). This time, the corona discharge was interesting, with uneven particle ions of Cr+W. While it has not been confirmed whether the bactericidal effect of W particles is as antibacterial as that of silver, copper, zinc, cobalt, or nickel, when humidity is added to the metal ions, the difference in ions does produce a bactericidal effect. Literature indicates that Cr, Mo, and Zn have antibacterial properties, so it is thought that W is due to its Cr content.

[0033] There are four types of electrical discharge: corona discharge, glow discharge, spark discharge, and arc discharge. Ozone can also be generated by corona discharge and glow discharge. When the potential difference between electrodes is increased, the air between the electrodes breaks down, allowing current to flow. This reacts with the 21% oxygen in the air in the following order: O2 → O + O → O + O2 → O3, producing O3 gas. The melting points of Cr and W are close to 1:2, and the number of ions with a potential difference of approximately 6% between the two creates a coastal discharge in a 0.1mm thick x 35mm long Cu-P pipe attached to the center, with a delay of approximately 6%. Because the uneven ionization current randomizes the corona discharge, the repeated fluctuations in strength improve the ozonation power. Furthermore, a 900G magnetic field is passed through the ozone layer to protect it from proton ions blown in from the sun, creating unprecedented ozone.

[0034] O3 is generated by uneven ion current, but conventionally, ozone is generated from a pipe that enters through a hole of the same diameter and exits through the same hole. Air expansion due to high heat only increases the flow rate, but this results in poor O3 generation. Therefore, in order to compensate for the air expanding by nearly 30%, a Venturi tube system is used to supply air, and by maintaining a constant flow, the previous maximum of 30% has been improved.

[0035] <CuB plating with a glaze similar to enamel on the inner surface of a quartz pipe discharge tube 203> By baking acid (H3BO3) alone and copper ions such as Cu(BF4)2, CuCl2, and CuCO3 at 650-850°C, a copper glaze can be placed on SiO2, making CuB plating possible.

[0036] The SiO2 of quartz pipe 308 cannot be 100% chemically plated. Furthermore, no expensive reducing agent such as Pd is required. A 50:50 mixture of boric acid (180-800°C) and copper chloride (650°C) powders was used, and the mixture was held at a maximum of 700°C for 30 minutes, making it possible to perform thermal plating. It is not a flux, but rather a simple mixture of the two types of materials, and the quartz pipe was melted and baked onto this flux using a convection method. This method results in a state where SiO2 + H3BO3 + CuCl2 are attached, so the thermal plating is not stable and there is some variation, but for the first time, plating was possible without using expensive AIP or CVD (thermal plating).

[0037] Fusion baking was performed at 850°C only in the final process. CuBF4 (copper borofluoride) is used at around 800°C. The halogens F, Cl, and Br are absolutely necessary for etching the quartz pipe 308. Boric acid and CuCl2 (copper chloride), H3BO3 (boric acid) and CuBF4 (copper borofluoride) can be used up to a maximum of 800°C. Normal plating methods do not allow 100% plating to be achieved on the quartz pipe 308 of the ozone generating discharge tube 300. SiO2 is also impossible to achieve with etching methods (halogen-HF). For this reason, the AIP method was resorted to, but enamel is baked at 700-800°C. With a viscous material like enamel, it is impossible to use spring force to adhere the Cu-P foil to the inner surface of the quartz pipe 308. The need for a liquid baking flux means that even after applying and baking 10 times, the resulting film is only 1 μm-2 μm thick. It is important that the baking flux is 100% liquid.

[0038] The inventors have the technology to make liquid brazing flux, as shown in Patent No. 4736105, so this is possible, but it was extremely difficult to make SiO2. In a heating furnace, H3BO3 (boric acid: 180-800°C) evaporates, so to make it liquid, CuCl2 (copper chloride, 650°C) is added, and these two are placed in separate containers and the evaporation and ionization of the flux allows for plating, but this takes a long time at 850°C, making it unproductive.

[0039] The inventor has attempted numerous chemical plating experiments on quartz (SiO2) over the past three years, but was unable to achieve fusion without heating to 500-800°C. He experimented with adding metal ions (Xn, Cu, Ni, Sn, Sb, Cr, Fe) to a 100% halogen flux, and even experimented with cyanide (Nc) for stability, but 100% plating was impossible despite several hundred attempts. The firing flux (a type of enamel) is 100% enamel-like. Because SiO2 can withstand temperatures up to 1800°C, it becomes a flux similar to a glassy glaze. Because SiO2 can withstand temperatures up to 1800°C, creating a glaze at 600-800°C eliminates the need for expensive AIP or CVD processes. It cannot be called a brazing flux, but is more like enamel. The inventor spent 42 years developing fluxes for a welding rod manufacturer, primarily focused on brazing, and believed he could tackle SiO2 with relatively little resistance. He considered it a mere extension of the soldering flux used for ceramics, but it took three years. The main reason for this was his decision not to use platinum group elements such as Pd, Ir, Pt, and Ru, which act as inorganic reduction catalysts. PdCl2 is also used for glass plating, but nothing more expensive than gold is used. Cost-wise, costs over ¥30,000 per gram are possible for automobile catalysts, but such expensive metals cannot be used in equipment costing several tens of thousands of yen. The aforementioned (0025) was successful, so the composition is shown, but because it is 100% liquid, it takes about 10 baking processes to achieve a thickness of 1 μm to 2 μm. Copper plating is possible with this level of flux if using an ozone generator with a similar level of SiO2.

[0040] Plating of quartz pipe 308 became possible using the liquid flux baking method (MAX 850℃), but the thickness was 1μm after 5 bakings. After 3 years of chemical plating, it was discovered that plating of quartz pipe 308 is nearly 100% impossible except by CVD and AIP, which is vapor deposition plating by heating (700-800℃). The flux produced in the final process described above is baked at 850°C with a maximum of 130cc per batch, gradually concentrating in the atmosphere inside a small vial. The vial is 15mm diameter x 13mm diameter x 50mm long, so the flux is baked in the atmosphere at 850°C and then rapidly cooled inside the vial (100°C). It gradually thickens, reaching a thickness of 1µm after 5-6 baking passes. Because the product is small, it is not produced in large quantities. This is because it is not chemical plating, and the reactions in each piece are random. It is a handmade baking plating. Similar to enamel, it is baked using a gas burner at 800-850°C. It would be ideal if it could be done 360° all at once, like with high frequency, but we lack the funds. If Ar gas is injected and sealed in after each application of the final liquid flux and the temperature is raised to 850°C, it will not turn into copper oxide, making it possible to create a quartz pipe discharge tube for use as a perfect O3 generator.
