Definitions
- the present invention relates to a method for producing a product that releases chlorine dioxide. Specifically, in order to release chlorine dioxide slowly, the present invention mixes substances that react with moisture to generate chlorine dioxide, compresses them into one tablet, and mixes them with a substance that absorbs moisture and packs them. how to create it.
- Chlorine dioxide is a very strong oxidizing agent and is excellent as a disinfectant or disinfectant.
- chlorine dioxide exists as a gas in a natural state, and there is a risk of explosion even if it is only 10% in the atmosphere. Therefore, it is useful to make and use low-concentration chlorine dioxide gas in the field by using precursors and active materials that have stable chemical reactions.
- a precursor sodium chlorite is representative.
- the active material is mainly acid. That is, the precursor reacts with the acid to give ClO2 -.
- Weak acids are mainly used to produce low-concentration chlorine dioxide gas.
- alkali metals or alkaline earth metal chlorites continuously react with precursors such as sodium chlorite to generate chlorine dioxide.
- the U.S. Department of Labor has set a chlorine dioxide concentration of 0.1 ppm/L, which is not harmful to workers who work 40 hours a week. And it is important to generate chlorine dioxide at a low concentration because most of the bacteria were killed within a few minutes to 24 hours at 0.01 ⁇ 0.05ppm as a result of various experiments. And since chlorine dioxide gas has a very strong property of being dissolved in water when it comes into contact with water, it is dissolved in the alveoli through human respiration and kills bacteria attached to the alveoli or floating in the lungs. In the case of an adult, since the respiratory rate is 6-7 liters per minute, chlorine dioxide gas is eliminated by the user.
- conventional products that generate chlorine dioxide generally separate and store chlorite and organic acid and mix them when using, or separate and store chlorite and persulfate with a thickener and absorbent resin and mix to generate chlorine dioxide. is composed
- these conventional products generate excessive chlorine dioxide at the beginning of use, causing rejection by the smell of chlorine dioxide and safety problems due to excessive exposure to chlorine dioxide. Since the difference in the amount of chlorine dioxide generated at the beginning and the second half is quite large, the effect of chlorine dioxide is hardly obtained in the second half of use.
- Patent Publication Nos. 10-2019-0084395 and Patent Publication No. 10-2015-010816 a method of absorbing chlorine dioxide into an adsorbent or a gel composition and packaging it in a porous film has been proposed, but these methods are also Since it is difficult to control the emission amount of chlorine uniformly, the emission amount of chlorine dioxide is not uniform, so excessive chlorine dioxide is released at the beginning of use and the amount is insignificant at the end of use. It has a disadvantage that it is difficult to continuously expect it over a long period of time.
- At least one precursor material, a reactant material, and a buffer material are separated from each other in the gel to cause a reaction, and contact is not made, and the reaction is provided from the beginning to obtain sustained release for a desired period.
- a material providing chlorine dioxide and a reactant such as a solid acid that reacts with it to generate chlorine dioxide, a buffer material that controls acidity, or a preservation material that increases the period of content in water of chlorine dioxide, etc. Compress and make a tablet using a device, mix it with a substance that absorbs moisture, and use it to release chlorine dioxide.
- Chlorine dioxide gas is used as a disinfectant, disinfectant, and deodorant.
- a product that generates chlorine dioxide gas in any space, at any concentration, and for any period, so the application is infinite. Through this, it can be used not only in human health, but also in the fields of veterinary quarantine and distribution of fresh food.
- the method of the present invention encompasses all methods for generating chlorine dioxide.
- An example is the reaction of sodium chlorate with a hydrogen chloride-based acid.
- the component to be produced through this invention is chlorine dioxide gas, and this gas is typically used as a disinfectant, disinfectant, and deodorant.
- the content component is chlorine dioxide water of any concentration.
- the content component is a precursor component that produces chlorine dioxide and a component that reacts therewith to activate chlorine dioxide production.
- a desiccant capable of absorbing moisture is provided.
- the desiccant items include the most common silica gel, calcium chloride, etc., dry cellulose such as wood pulp, dehydrated polymer such as polyamide, xantham, agar, alginate, guar, etc. Any material that can absorb moisture is included.
- the principle of action of the desiccant is that it absorbs moisture and supplies moisture to the tablets mixed together, and at the same time absorbs chlorine dioxide gas first. In addition, if the amount of chlorine dioxide generated from the tablet is reduced, chlorine dioxide is also released from the desiccant at the same time, and the sustained release property is increased.
- a component that becomes a gel upon absorption of moisture such as calcium chloride, is more effective.
- Preferred content components in the present invention are a precursor component that generates chlorine dioxide and a component that reacts with the precursor component to activate chlorine dioxide production. Mix these substances well and make a tablet by high-pressure compression, and when it comes into contact with a desiccant, in this case, the tablet meets moisture and reacts slowly to generate chlorine dioxide, some of which is released into the air, and some of it is added to the desiccant. It is absorbed and then released into the air when the amount of chlorine dioxide gas generated is reduced in the future purification. In other words, due to the nature of the tablet to generate chlorine dioxide when it comes into contact with water, all reactions do not occur at once, and as time goes by, as the desiccant absorbs moisture, the content components are gradually released. It is one of the key technologies to emit.
- a substance capable of controlling the rate/stability of a chemical reaction acts as a buffer. This is for the control of pH, that is, acidity.
- Alkaline phosphate is representative, disodium hydrogen phosphate, trisodium phosphate, tetrasodium pyrophosphate, sodium hexameta phosphate, sodium triphosphate tripolyphosphate), sodium dihydrogen phosphate, etc. are commonly used, and solid acids are also included. buffers known to those skilled in the art.
- a highly preferred container in the present invention should be UV protected.
- the opaque container shall be made of a barrier material. This is regardless of whether an opaque material that does not pass UV is used, or a material that blocks UV in the form of paint on top of a material that passes UV, surrounds it in the form of a film/film, or is attached through an adhesive.
- UV protection methods UV reduces the chlorine dioxide gas that has already been generated.
- the pH in the container is about 1.5 to about 5, preferably about 2 to about 4, more preferably about 2.5 to about 3.5 is preferred.
- Sodium chlorite in this case is preferably a commercial grade 80% formulation.
- the pH is preferably 2-3.
- reaction formula of alkali metal and alkaline earth metal chloride is as follows.
