Description

FLARE COMPOSITION FOR WEATHER CONTROL

The present invention relates to a weather-controlling combustible composition, and more specifically, to a weather-controlling combustible composition having excellent artificial rain formation and fog dissipation efficiency without using any of the main raw materials of gunpowder as defined in the Act on Safety Management of Firearms, Swords, Explosives, etc. (hereinafter referred to as the “Firearms and Explosives Act”).

Weather control methods are mainly carried out by spraying seeding materials into the moist atmosphere in the form of aerosols of various chemical compositions, and by spraying such seeding materials, the purpose of hail suppression, fog dissipation, or rainfall control can be achieved.

That is, when seeding materials are artificially sprayed into clouds or the like, they are sprayed in an aerosol state, and these sprayed aerosols act as active centers for heterogeneous nucleation of water in the atmosphere, causing a local drop in the surrounding water vapor pressure, thereby inducing the continuous growth of water droplets or ice crystals. Meanwhile, the numerous nucleation active centers created by the dispersion of nucleating agents are used as a measure of weather control efficiency.

Meanwhile, hail, fog, and drought are factors that cause considerable harm to essential human daily life. In particular, traffic accidents caused by fog account for a significant proportion of all traffic accidents each year, and drought causes serious water shortages, including drinking water and agricultural water.

Meanwhile, conventionally used weather-controlling flares use potassium perchlorate, potassium chlorate, potassium nitrate, etc. as oxidizers, and since these substances are classified as "explosives" as stipulated in the Firearms and Explosives Act, the procedures for manufacturing, storing, and using weather-controlling flares using these substances take a lot of time, and it is difficult to respond quickly during weather-control work, which makes weather-control work very difficult, and this limits the quick response at the application site.

Therefore, there is an urgent need to develop a weather-controlling combustion bomb that is not subject to the restrictions of the above firearms and explosives law, is safe to handle, and has excellent artificial rain formation and fog dissipation efficiency.

Patent Document 1: Republic of Korea Patent Publication No. 10-1348115 (January 8, 2014)

Accordingly, in order to solve the above problem, the present invention accidentally discovered that a weather-controlling combustible composition comprising a compound having a specific chemical formula with a low nitrogen content and sodium bicarbonate can be used to manufacture a weather-controlling combustible composition that is not subject to the restrictions of the Firearms and Explosives Act and is safe to handle while having very excellent artificial rain formation and fog dissipation efficiency, and the present invention was completed based on this.

A non-explosive, weather-controlled combustion bomb composition according to one embodiment of the present invention comprises a compound having the following chemical formula 1; and

[Chemical Formula 1] - C ₆ H ₈ (ONO ₂ ) ₂ O ₂

Contains bicarbonate of soda;

A non-explosive, weather-controlled combustible composition according to one embodiment of the present invention further comprises magnesium and calcium chloride.

A non-explosive, weather-controlled combustion grenade composition according to one embodiment of the present invention further comprises polytetrafluoroethylene (PTFE).

A non-explosive, weather-controlled combustible composition according to one embodiment of the present invention further comprises a compound having a chemical structure of C ₂₁ H ₂₅ ClO ₅ .

A non-explosive, weather-controlled combustion bomb composition according to one embodiment of the present invention further comprises diphenylamine (C ₁₂ H ₁₁ N).

The weather-controlling combustion bomb composition according to the present invention has the advantage of having excellent artificial rain formation and fog dissipation efficiency without using any of the main raw materials of gunpowder as stipulated in the Firearms and Explosives Act.

Before explaining the present invention in more detail, it should be noted that the terms and words used in this specification and claims should not be limited to their conventional or dictionary meanings, but should be interpreted with meanings and concepts consistent with the technical spirit of the present invention based on the principle that the concepts of terms can be appropriately defined to best explain the invention. Accordingly, the configuration of the embodiments described in this specification is merely a preferred example of the present invention and does not represent the entire technical spirit of the present invention. Therefore, it should be understood that various equivalents and modified examples may exist as of the time of this application.

Hereinafter, preferred embodiments of the present invention will be described in detail so that a person having ordinary skill in the art to which the present invention pertains can easily practice the present invention.

The present invention relates to a weather-controlling combustible composition, and more particularly, to a weather-controlling combustible composition having excellent artificial rain formation and fog dissipation efficiency without using any of the main raw materials of gunpowder as prescribed in the Firearms and Explosives Act.

A non-explosive, weather-controlled combustion bomb composition according to one embodiment of the present invention comprises a compound of the following chemical formula 1; and

[Chemical Formula 1]

C ₆ H ₈ (ONO ₂ ) ₂ O ₂

Contains bicarbonate of soda;

That is, Article 5, Paragraph 2, Subparagraph 5 of the Enforcement Decree of the Act on the Safety Management of Firearms, Swords, Explosives, etc. stipulates that cotton (nitrocellulose) with a nitrogen content of 12.2% or more is a gunpowder under the Act on the Safety Management of Firearms, Swords, Explosives, etc.

This is because cotton (nitrocellulose) with a nitrogen content of 12.2% or more has very strong explosive power.

On the other hand, there was a problem that when the nitrogen content was less than 12.2%, the explosive power was drastically weakened, making it almost impossible to use it in fields that required a certain explosive power, such as weather control flares.

Accordingly, the inventor of the present invention discovered that when a compound having the molecular structure of the following chemical formula 1 is mixed with sodium bicarbonate among cotton (nitrocellulose) having a nitrogen content of less than 12.2%, it can have a very efficient artificial rain formation and fog dissipation effect without being subject to the provisions of the Firearms and Explosives Act.

[Chemical Formula 1]

C ₆ H ₈ (ONO ₂ ) ₂ O ₂

Meanwhile, it was discovered that when the compound of the above chemical formula 1 is mixed with sodium bicarbonate and magnesium and calcium chloride are further included, the artificial rain formation effect is further improved.

In addition, the inventors of the present invention have found that when polytetrafluoroethylene (PTFE), a compound commonly called Teflon, is further included together with the compound of the above chemical formula 1, sodium bicarbonate, magnesium and calcium chloride, the artificial rain formation and fog dissipation effects are further improved.

In addition, the inventors of the present invention found that when a compound having a chemical structure of C ₂₁ H ₂₅ ClO ₅ is further included together with the compound of the above chemical formula 1, sodium bicarbonate, magnesium, calcium chloride, and polytetrafluoroethylene (PTFE), the artificial rain formation and fog dissipation effects are further improved.

In addition, the inventors of the present invention found that when diphenylamine (C ₁₂ H ₁₁ N) is further included together with the compound of the above chemical formula 1, sodium bicarbonate, magnesium, calcium chloride, polytetrafluoroethylene (PTFE), and a compound having a chemical structure of C ₂₁ H ₂₅ ClO ₅ , the artificial rain formation and fog dissipation effects are further improved.

The weather-controlling combustion grenade composition according to the present invention can be manufactured as a calcium chloride type and a silver iodide type combustion grenade composition, respectively.
