Description
본 발명은 폐소화약제를 포함하는 투척식 소화기용 소화약제에 관한 것으로서, 더욱 상세하게는, 폐소화약제를 재처리하여 수득되는 소화약제를 포함하여 투척식 소화기에 적합한 소화성능을 나타내는 소화약제에 관한 것이다.The present invention relates to a fire extinguishing agent for a throwing fire extinguisher containing a waste fire extinguishing agent, and more particularly, to a fire extinguishing agent exhibiting fire extinguishing performance suitable for a throwing fire extinguisher, including a fire extinguishing agent obtained by reprocessing a waste fire extinguishing agent. it's about
소화는 연소 현상을 인위적으로 중지시키는 것으로서, 냉각에 의해 연소 온도를 낮추거나, 산소의 공급을 차단하는 질식, 가연물을 화점으로부터 제거하거나 하여 연소의 연쇄 반응을 차단시키는 방법을 통해 이루어진다. 이를 위하여, 물에 소화약제를 첨가제로 혼합한 후 여기에 공기를 주입하면 기포(foam)가 발생되어 연소물의 표면을 덮게 되며, 이를 통해 질식 효과와 함께 물의 냉각 효과에 의해 화재를 진화할 수 있다. 또한, 상기 소화약제로는 고체 분말 소화약제가 사용되는데, 탄산수소나트륨, 탄산수소칼륨, 제1인산암모늄 등의 물질을 미세한 분말로 만들어 유동성을 높인 후, 이를 불연성 가스 압력으로 분출시켜 사용한다.Extinguishing is to artificially stop the combustion phenomenon, and it is performed by lowering the combustion temperature by cooling, suffocating by blocking the supply of oxygen, or blocking the chain reaction of combustion by removing combustibles from the ignition point. To this end, when a fire extinguishing agent is mixed with water as an additive and air is injected therein, foam is generated to cover the surface of the burning object, through which the fire can be extinguished by the cooling effect of water along with the suffocation effect. . In addition, as the fire extinguishing agent, a solid powder fire extinguishing agent is used. After increasing fluidity by making materials such as sodium hydrogen carbonate, potassium hydrogen carbonate, monobasic phosphate, etc. into fine powder, it is ejected and used under non-flammable gas pressure.
분사에 의해 소화하는 분말 소화기 외에 투척식 소화기도 개발되고 있는데, 이는 화재 현장에 투척하면 투척시 충격이나 화재에 의해 용기가 파괴되어 화재를 진화할 수 있는 소화기이다. 상기 투척식 소화기는 종래의 분말식 소화기에 비하여 무게가 가볍고, 사용법을 익힐 필요가 없으며, 원거리에서 사용 가능한 장점이 있으나, 분사력이 없어 소화액을 널리 분사하지 못하므로 넓은 범위의 진화가 어렵거나 투척 시의 충격이 부족하여 액체의 분출에 실패하는 문제가 있고, 투척에 따라 형성된 파편에 사용자 등이 부상을 입을 수 있으며, 소화약제의 종류에 따라 B급 및 C급 화재에는 대응이 불가능하기 때문에 이를 해결할 수 있는 투척식 소화기의 개발이 요구되고 있다.In addition to a powder fire extinguisher that extinguishes by spraying, a throwing type fire extinguisher is also being developed, which is a fire extinguisher capable of extinguishing a fire by destroying a container by an impact or fire when thrown at a fire site. The throw-type fire extinguisher has the advantage of being lighter in weight than the conventional powder fire extinguisher, requiring no learning how to use it, and being able to use it at a distance, but it is difficult to extinguish a wide range because it does not spray fire extinguishing fluid widely due to lack of spray power. There is a problem that liquid ejection fails due to lack of impact, and users may be injured by fragments formed by throwing, and it is impossible to respond to Class B and C fires depending on the type of fire extinguishing agent. There is a demand for the development of a throwable fire extinguisher.
최근에는 상기 소화약제로서 폐소화기에서 회수된 소화약제를 재활용하는 기술이 개발되고 있다. 예를 들어, 대한민국 등록특허공보 10-1738663호에서는 회수, 건조, 선별 공정을 거쳐 분말 소화기의 소화약제를 회수 및 재생하는 기술이 공지되어 있고, 대한민국 등록특허공보 10-1998080호에서는 인산암모늄의 실리콘 코팅을 분해하여 미분말 상태로 회수함으로써 비료로 활용하는 기술이 공지되어 있다.Recently, a technology for recycling the fire extinguishing agent recovered from the waste fire extinguisher as the fire extinguishing agent has been developed. For example, in Korean Patent Registration No. 10-1738663, a technique for recovering and regenerating the fire extinguishing agent of a powder fire extinguisher through recovery, drying, and sorting processes is known, and in Korean Patent Registration No. 10-1998080, silicon of ammonium phosphate A technique of disassembling the coating and recovering it in a fine powder state to use it as a fertilizer is known.
특히, 소화약제로 사용되는 인산암모늄은 방습가공을 해야 하기 때문에 실리콘 오일 등을 사용하여 코팅층이 형성되어 있는데, 이러한 코팅된 인산암모늄은 분말 소화기의 소화약제로는 적합하나 투적식 소화기에서는 빠른 소화가 어렵기 때문에 이를 소화약제 성분과 분리 및 제거할 필요가 있다.In particular, since ammonium phosphate used as a fire extinguishing agent needs moisture-proof processing, a coating layer is formed using silicone oil. Such coated ammonium phosphate is suitable as an extinguishing agent for a powder fire extinguisher, but is difficult to extinguish quickly in a drop type fire extinguisher. Because it is difficult, it is necessary to separate and remove it from the fire extinguishing agent component.
상기 선행기술에서는 커피분, EM 효소, 유산균을 혼합 및 발효시켜 카페인 분해처리된 커피분을 천연 분해제로 사용하여 실리콘 성분을 분해하고 있으나, 이는 비료의 제조공정에 적합할 뿐 투척식 소화기용 소화약제를 제조하는 공정에서는 공정 효율과 분리 정제 과정이 복합하여 비효율적이다.In the prior art, the coffee powder, EM enzyme, and lactic acid bacteria are mixed and fermented to decompose the silicone component by using the caffeine-decomposed coffee powder as a natural decomposer. In the manufacturing process, process efficiency and separation and purification processes are complex and inefficient.
또한, 일본 공개특허공보 특개2013-255880호에는 소화약제의 친수화 처리를 위하여 알코올 수용액을 분무하여 소화약제 분말의 실리콘 코팅을 제거하는 기술이 공지되어 있다. 그러나 상기 선행기술은 친수화 처리를 통해 소화약제 성분의 표면을 활성화시켜 안료로 사용하는 기술로서 실리콘 성분을 소화약제와 분리하기에는 적합하지 않은 기술이다.In addition, Japanese Unexamined Patent Publication No. 2013-255880 discloses a technique of removing the silicone coating of the fire extinguishing agent powder by spraying an alcohol aqueous solution for hydrophilization of the fire extinguishing agent. However, the prior art is a technology that activates the surface of the fire extinguishing agent component through hydrophilization treatment and uses it as a pigment, and is not suitable for separating the silicone component from the fire extinguishing agent.
본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 투척식 소화기에 사용하기에 적합한 소화약제를 제조하되 폐소화약제를 재활용하여 소화약제를 제조하는 방법을 제공하는 것을 그 목적으로 한다.The present invention has been made to solve the problems of the prior art as described above, and to manufacture a fire extinguishing agent suitable for use in a throwing type fire extinguisher, but to provide a method for manufacturing a fire extinguishing agent by recycling waste fire extinguishing agent. do.

이하 본 발명을 보다 상세히 설명한다. 본 명세서 및 청구범위에 사용된 용어나 단어는 통상적이거나 사전적인 의미로 한정해서 해석되어서는 아니되며, 발명자는 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.Hereinafter, the present invention will be described in more detail. Terms or words used in this specification and claims should not be construed as being limited to ordinary or dictionary meanings, and the inventor may appropriately define the concept of terms in order to explain his or her invention in the best way. It should be interpreted as a meaning and concept consistent with the technical spirit of the present invention based on the principle that there is.
본 발명에 따른 소화약제의 제조방법은 도 1에 도시된 것과 같은 공정을 통해 수행될 수 있다. 즉, 폐소화기로부터 폐소화약제를 수득하고, 상기 폐소화약제 및 이소프로판올(isopropanol)을 혼합하여 혼합액을 제조한 후, 상기 혼합액을 정치하여 층 분리하고 실리콘 성분이 포함된 이소프로판올을 분리하며, 상기 혼합액을 여과하고 정제수를 혼합하여 소화약제 수용액을 제조하고, 상기 소화약제 수용액을 정치하여 층 분리하고, 실리카 미립자를 분리한 후, 상기 소화약제 수용액에 비할로겐 유기계 혼합물 및 계면활성제, 점증제, 냉각제, 결빙제에서 선택되는 어느 하나 또는 그 이상의 첨가제를 혼합하여 소화약제를 제조하는 단계를 통해 소화약제를 제조할 수 있다.The manufacturing method of the fire extinguishing agent according to the present invention may be performed through a process as shown in FIG. That is, after obtaining a waste fire extinguishing agent from a waste fire extinguisher, mixing the waste fire extinguishing agent and isopropanol to prepare a mixed solution, the mixed solution is allowed to stand to separate layers, and isopropanol containing a silicon component is separated, and the mixed solution is filtered and mixed with purified water to prepare an aqueous solution of fire extinguishing agent, the aqueous solution of fire extinguishing agent is left still to separate the layers, and after separating silica fine particles, the aqueous solution of fire extinguishing agent contains a non-halogen organic mixture and a surfactant, a thickener, a coolant, The fire extinguishing agent may be prepared through the step of preparing the fire extinguishing agent by mixing any one or more additives selected from the freezing agent.
일반적으로 페기된 분말 소화기로부터 수득되는 분말 소화약제는 재활용되어 소화약제로 사용되나, 응집된 분말의 경우 재활용이 어려운 문제점이 있다. 본 발명의 제조공정에서 사용되는 폐소화약제는 이러한 응집된 분말 소화약제를 주로 원료로 사용한다.In general, powder fire extinguishing agents obtained from discarded powder fire extinguishers are recycled and used as fire extinguishing agents, but in the case of agglomerated powder, recycling is difficult. The waste fire extinguishing agent used in the manufacturing process of the present invention mainly uses such agglomerated powder fire extinguishing agent as a raw material.
일반적으로는 계면활성제를 부가하여 친수성을 증가시켜 재사용할 수 있으나, 본 발명에서는 폐소화약재 분말의 표면을 코팅하고 있는 실리콘 성분을 용매를 사용하여 제거한 후 회수된 소화약제를 사용하고 있다. 수동식 분말 소화기(ABC 소화기)의 경우 소화약제를 구성하는 주성분이 제1인산암모늄이며, 탄산암모늄, 중탄산암모늄. 제2인산암모늄. 제3인산암모늄, 요소 등의 무기계 소화약제 분말 성분을 함유하고 있다. 이러한 소화약제는 대기 중의 수분에 의해 응집되어 고화되기 때문에 화재 현장에서 분사되지 않는 문제점이 발생한다. 이로 인하여, 장기간 뭉치지 않고 미분말 상태를 유지할 수 있도록 분말의 표면에 방습 코팅제로 실리콘 오일을 코팅하며, 수분 흡수를 위하여 실리카 미립자를 첨가하고 있다. 상기 방습 코팅제는 전체 분말의 질량 대비 약 2질량% 정도 함유되는 것으로 알려져 있으며, 상기 방습 코팅제와 실리카 분말을 제거해야 소화약제로서의 성능을 얻을 수 있다. 즉, 분말 소화기의 경우 보관 후 화재 발생시 분사하기 위하여 방습 코팅제와 실리카 미립자를 첨가하고 있으나, 투척용 소화기의 경우 분사 방식이 아니므로 이러한 코팅제나 실리카가 소화 성능을 오히려 저하시키는 원인이 되므로 폐소화약제를 재활용하기 위해서는 이러한 불필요한 성분을 제거할 필요가 있다.In general, it can be reused by adding a surfactant to increase hydrophilicity, but in the present invention, the recovered fire extinguishing agent is used after removing the silicone component coating the surface of the spent fire extinguishing agent powder using a solvent. In the case of a manual powder fire extinguisher (ABC fire extinguisher), the main components constituting the fire extinguishing agent are monobasic ammonium phosphate, ammonium carbonate and ammonium bicarbonate. dibasic ammonium phosphate. Contains inorganic fire extinguishing agent powder components such as triammonium phosphate and urea. Since these fire extinguishing agents are condensed and solidified by moisture in the air, there is a problem in that they are not sprayed at the fire site. For this reason, silicone oil is coated with a moisture-proof coating agent on the surface of the powder to maintain a fine powder state without aggregation for a long time, and silica fine particles are added for moisture absorption. The moisture-proof coating agent is known to contain about 2% by mass relative to the total weight of the powder, and the performance as a fire extinguishing agent can be obtained only when the moisture-proof coating agent and the silica powder are removed. That is, in the case of powder fire extinguishers, moisture-proof coatings and silica fine particles are added to spray in case of fire after storage, but in the case of throw fire extinguishers, it is not a spray method, so these coatings or silica rather reduce the fire extinguishing performance. To recycle, it is necessary to remove these unnecessary components.
따라서 상기 폐소화약제의 코팅층을 제거하기 위하여 본 발명에서는 응집된 형태로 회수된 폐소화약제 분말을 이소프로판올(isopropyl alcohol, IPA)에 투입하고 일정시간 혼합한 다음 정치시키게 되면 실리콘 오일과 IPA가 혼합된 상등액과 ADP를 포함하는 분말 소화약제와 실리카가 혼합된 침전층으로 층 분리된다. 상기 상등액을 제거하고 적당량의 정제수를 혼합하면 소화약제 수용액을 수득할 수 있고, 상기 소화약제 수용액을 정치하면 실리카 성분이 부유하게 되므로 이를 통해 실리카를 제거할 수 있다.Therefore, in order to remove the coating layer of the waste fire extinguishing agent, in the present invention, the waste fire extinguishing agent powder recovered in the form of agglomeration is put into isopropanol (isopropyl alcohol, IPA), mixed for a certain period of time, and then left to stand. Silicone oil and IPA are mixed. The layers are separated into a precipitate layer in which the supernatant, powdered fire extinguishing agent including ADP, and silica are mixed. When the supernatant is removed and an appropriate amount of purified water is mixed, an aqueous solution of fire extinguishing agent can be obtained, and when the aqueous solution of fire extinguishing agent is left still, the silica component is suspended, so silica can be removed through this.
또한, 상등액을 구성하는 IPA는 끓는점이 82.3℃이므로 증류에 의해 회수할 수 있어 재사용하게 되며, 증류 과정에서 실리콘 오일을 따로 회수할 수 있다. 또한, 상기 소화약제 수용액에 부유하는 실리카 미립자도 따로 회수할 수 있게 된다.In addition, since IPA constituting the supernatant has a boiling point of 82.3 ° C., it can be recovered by distillation and reused, and silicone oil can be separately recovered during the distillation process. In addition, the silica fine particles floating in the aqueous solution of the fire extinguishing agent can also be separately recovered.
또한, 수득된 소화약제 수용액에 투척식 소화기에 적용할 수 있도록 필요한 다른 첨가제를 혼합하여 목적하는 투척식 소화기용 소화약제를 수득하게 된다.In addition, the obtained fire extinguishing agent solution is mixed with other additives necessary for application to the throwing type fire extinguisher to obtain the desired fire extinguishing agent for the throwing type fire extinguisher.
본 발명의 제조방법을 구체적으로 설명하면 다음과 같다.The manufacturing method of the present invention is described in detail as follows.
먼저 IPA를 사용하여 폐소화약제 분말에서 방습 코팅제를 제거하는 공정을 수행한다. 폐소화약제 분말(응집 분말)과 IPA를 각각 1:1의 중량비로 혼합한 다음 2 내지 5분간 정치시킨다. 이때, 혼합을 위하여 습식 분쇄하여 분쇄 및 혼합을 수행할 수 있다. 상기 습식 분쇄는 유성밀을 이용할 수 있으며 300 내지 500rpm에서 10 내지 30분 동안 분쇄하면 응집 분말이 50 내지 100㎛ 정도의 입자로 분쇄되게 된다.First, a process of removing the moisture-proof coating agent from the spent fire extinguishing agent powder using IPA is performed. Waste extinguishing agent powder (agglomerated powder) and IPA are mixed in a weight ratio of 1:1, respectively, and then allowed to stand for 2 to 5 minutes. At this time, grinding and mixing may be performed by wet grinding for mixing. The wet grinding may use a planetary mill, and when grinding at 300 to 500 rpm for 10 to 30 minutes, the agglomerated powder is pulverized into particles of about 50 to 100 μm.
상기 상등액을 제거한 후 수득된 침전층 내의 침전물을 XRF로 분석한 결과 표 1과 같은 성분 및 함량을 나타내는 것으로 확인되었다.As a result of XRF analysis of the precipitate in the precipitate layer obtained after removing the supernatant, it was confirmed that the components and contents shown in Table 1 were shown.
표 1에 따른 분석 결과로부터 폐소화약제와 대비하여 침전물(S1), 침전물(S2)에서 P2O5의 상대적 함량이 2.23 내지 3.14 중량% 증가하면서 SiO2 함량은 2.74 내지 3.49 중량% 감소하는 결과를 나타내는 것을 알 수 있다. 이는 IPA 첨가시 실리콘 오일 용해로부터 얻어진 결과인 것으로 확인되었다. From the analysis results according to Table 1, the relative content of P 2 O 5 in the precipitate (S1) and precipitate (S2) increased by 2.23 to 3.14 wt%, compared to the waste extinguishing agent, while the SiO 2 content decreased by 2.74 to 3.49 wt%. It can be seen that represents This was confirmed to be a result obtained from silicone oil dissolution upon addition of IPA.
또한, 침전물 중에 남은 SiO2 17.62 중량%는 폐소화약제(R)의 제조과정에서 첨가된 성분이며, 상기 실리카 성분은 전술한 바와 같이 수용액을 정치하면 부유하게 되므로 여과를 통해 분리될 수 있다. 상기 수용액을 정치하는 시간도 2 내지 5분이면 충분하다.In addition, 17.62% by weight of SiO 2 remaining in the precipitate is a component added during the manufacturing process of the spent fire extinguishing agent (R), and the silica component floats when the aqueous solution is left as described above, so it can be separated through filtration. 2 to 5 minutes is sufficient for the time for leaving the aqueous solution still.
상기 실리콘 성분을 분리하는 과정은 도 2를 통해서 알 수 있는데, 폐소화약제 분말과 IPA를 혼합한 후 정치하면 도 2(a)에서와 같이 상등액과 침전층으로 나뉘게 된다. 상기 상등액을 분리한 후 물로 희석하면 도 2(b)에서와 같이 IPA 수용액에 실리콘 성분이 분산된 상태를 확인할 수 있다.The process of separating the silicon component can be seen through FIG. 2. When the spent fire extinguishing agent powder and IPA are mixed and left to stand, the supernatant and the sediment layer are divided as shown in FIG. 2 (a). When the supernatant is separated and then diluted with water, it can be confirmed that the silicone component is dispersed in the IPA aqueous solution as shown in FIG. 2 (b).
상기 폐소화약제는 주로 무기계 성분으로 이루어져 있으며, 투척식 소화기의 소화약제로서의 성능을 향상시키기 위하여 비할로겐 유기계 소화약제를 추가할 수도 있다. 상기 비할로겐 유기계 소화약제로는 아데노신삼인산(ATP), 사이티딘 삼인산(CTP), 티미딘 삼인산(TTP) 및 구아노신 삼인산(GTP)에서 선택되는 어느 하나 또는 그 이상을 사용할 수 있다. 상기 유기계 소화약제는 난연 또는 소화 소재에 필수적으로 함유되는 인, 질소, 및 탄소를 포함하는 화합물로서 다른 첨가제 없이도 우수한 난연, 소화 특성을 나타낼 수 있으며 독성이 없어 친환경 소화약제로서도 사용되는 성분이다.The waste fire extinguishing agent is mainly composed of inorganic components, and a non-halogen organic fire extinguishing agent may be added to improve the performance of the fire extinguishing agent of the throwing type fire extinguisher. As the non-halogen organic fire extinguishing agent, any one or more selected from adenosine triphosphate (ATP), cytidine triphosphate (CTP), thymidine triphosphate (TTP) and guanosine triphosphate (GTP) may be used. The organic fire extinguishing agent is a compound containing phosphorus, nitrogen, and carbon that is essentially contained in flame retardant or fire extinguishing materials, and can exhibit excellent flame retardant and fire extinguishing properties without other additives, and is also used as an eco-friendly fire extinguishing agent because it is non-toxic.
또한, 상기 비할로겐 유기계 소화약제 외에도 계면활성제, 점증제, 냉각제, 결빙제에서 선택되는 어느 하나 또는 그 이상의 첨가제를 혼합할 수 있다.In addition to the non-halogen organic fire extinguishing agent, any one or more additives selected from surfactants, thickeners, coolants, and icing agents may be mixed.
상기 계면활성제는 물의 표면장력을 감소시켜 쉽게 거품을 형성하여 거품 안의 물이 밑으로 빠지는 속도가 줄게 되어서 고체 가연물의 화재 시 침투제(wetting agent) 역할을 할 수 있고, 거품을 발포함으로써 소화약제의 표면적을 늘리고 단시간 내에 소화약제의 온도를 높여서 다량의 불연성 가스를 발생하여 초기 화재 진화에 효과를 나타내기 위하여 첨가될 수 있다. 이러한 계면활성제로는 통상적으로 사용되는 양이온, 음이온 또는 비이온성 계면활성제를 사용할 수 있다. The surface active agent reduces the surface tension of water to easily form bubbles, thereby reducing the rate at which water in the bubbles falls to the bottom, so that it can act as a wetting agent in the event of a fire of solid combustibles, and by foaming the foam, the surface area of the fire extinguishing agent It can be added to increase the temperature of the fire extinguishing agent within a short period of time to generate a large amount of non-combustible gas to be effective in extinguishing the initial fire. As such a surfactant, commonly used cationic, anionic or nonionic surfactants may be used.
또한, 상기 점증제는 소화약제가 소화 물질의 표면에 오랜 시간 동안 점착되며, 목재, 종이, 섬유 등의 빠르게 침투되어 물성을 안정화시키고 효과적으로 소화할 수 있도록 첨가될 수 있다.In addition, the thickener may be added so that the fire extinguishing agent adheres to the surface of the fire extinguishing material for a long time and rapidly penetrates wood, paper, fiber, etc. to stabilize physical properties and effectively extinguish fire.
또한, 상기 냉각제는 연소에 의해 가열된 소화가스를 냉각시키기 위하여 첨가될 수 있으며, 각종 금속 또는 금속산화물을 사용할 수 있다.In addition, the coolant may be added to cool the digestion gas heated by combustion, and various metals or metal oxides may be used.
또한, 상기 결빙제는 사용 환경에 따라 결빙되는 환경에서도 사용할 수 있도록 첨가할 수 있는 성분으로 에틸렌글리콜 또는 프로필렌글리콜을 사용할 수 있다. 다만, 투척식 소화기의 특성상 실내에 보관하는 경우가 많으므로 이 경우 결빙제를 첨가하지 않아도 된다.In addition, the freezing agent may use ethylene glycol or propylene glycol as a component that can be added so that it can be used in a freezing environment depending on the use environment. However, due to the nature of throw-type fire extinguishers, they are often stored indoors, so in this case, it is not necessary to add an icing agent.
이와 같이 폐소화약제를 재생하여 수득된 상기 소화약제 수용액에 비할로겐 유기계 혼합물 및 각종 첨가제를 혼합함으로써 본 발명에서 목적하는 투척식 소화기용 소화약제를 제조할 수 있게 된다.In this way, by mixing the non-halogen organic mixture and various additives with the aqueous solution of the fire extinguishing agent obtained by regenerating the waste fire extinguishing agent, it is possible to manufacture the fire extinguishing agent for the throwing type fire extinguisher intended in the present invention.
본 발명의 제조방법에 따라 제조된 소화약제의 성능을 평가하기 위하여 소화약제의 표면장력, 응고점, 침전량, 부식성 등의 물성을 측정하였다. 상기 측정은 소방검정공사의 소화약제 형식승인 및 검정기술기준, 시험세칙에 준한 것이다.In order to evaluate the performance of the fire extinguishing agent prepared according to the manufacturing method of the present invention, physical properties such as surface tension, solidification point, precipitation amount, and corrosiveness of the fire extinguishing agent were measured. The measurement is in accordance with the fire extinguishing agent type approval and verification technical standard of the Fire Inspection Corporation, and the detailed test rules.
소화약제의 표면장력은 표면장력계를 사용하였으며 20±0.5℃의 온도 조건에서 측정하였다. 표면장력의 합격기준은 33dyne/㎝ 이하이며, 본 발명의 소화약제에 대해 3회 측정 후 평균값을 구한 결과 표면장력이 19.4dyne/㎝인 것으로 나타났다.The surface tension of the fire extinguishing agent was measured using a surface tensiometer at a temperature of 20 ± 0.5 ° C. The acceptance standard for surface tension is 33 dyne / cm or less, and as a result of obtaining the average value after measuring three times for the fire extinguishing agent of the present invention, it was found that the surface tension was 19.4 dyne / cm.
또한, 소화약제의 응고점은 18㎜의 시험관에 채취한 시료 10㎖를 주입한 후, 온도계를 넣고 한제욕조에서 냉각하되 과냉되지 않도록 하면서 온도계로 휘저어 결정이 석출하기 시작하면 한제욕조에서 들어낸 후, 계속 휘저어 결정이 없어지고 용액이 투명하게 되었을 때 온도를 읽어 측정하였으며, 3회 반복하여 평균값을 구하였다. 그 결과 투척식 소화기에서 요구되는 응고점 -20℃ 이하의 조건을 충족하는 것으로 나타났다.In addition, the freezing point of the fire extinguishing agent is after injecting 10 ml of the sample taken into an 18 mm test tube, inserting a thermometer and cooling it in a cryogenic bath, but stirring with a thermometer while not overcooling. When the crystals start to precipitate, When the crystals were removed by continuous stirring and the solution became transparent, the temperature was read and measured, and the average value was obtained by repeating three times. As a result, it was found that the conditions of freezing point -20 ℃ or less required for throwing fire extinguishers were met.
또한, 소화약제의 침전량을 측정하기 위하여 윤활유 침전가 시험 방법에 의하여 침전용 나프타를 첨가하지 않고 소화제의 액온을 20±0.5℃로 측정하였다. 침전량은 용적 0.1% 이하이어야 기준을 충족하는데, 본 발명의 소화약제의 경우 침전략이 0.1 용적% 이하의 조건을 충족하였다. 이는 폐소화약제의 코팅층을 제거하는 과정 없이 바로 사용하였을 때 침전량이 기준값을 넘어서는 것에 비해 향상된 효과로 확인되었다.In addition, in order to measure the precipitation amount of the fire extinguishing agent, the liquid temperature of the fire extinguishing agent was measured at 20 ± 0.5 ° C without adding naphtha for precipitation according to the lubricating oil precipitation value test method. The amount of precipitation must be 0.1% or less by volume to meet the standard. In the case of the fire extinguishing agent of the present invention, the precipitation strategy met the condition of 0.1% by volume or less. This was confirmed as an improved effect compared to the amount of precipitation exceeding the reference value when used directly without removing the coating layer of the spent fire extinguishing agent.
또한, 소화약제의 부식성 평가를 위하여 소화제에 강철(KSD3512 SCP1), 황동(KSD5201 C2801, KSD5101 C3771) 및 알루미늄(KSD6701 A5052P) 스테인리스(KSD3698 STS304)를 38±2℃에 21일 동안 놓아두어 중량손실을 측정하여 평가하였다. 중량손실은 각각 1일에 3㎎/20㎠ 이하이어야 기준을 충족하는 것인데, 본 발명의 소화약제는 모두 부식성 기준을 충족시키는 것으로 나타났다.In addition, in order to evaluate the corrosiveness of fire extinguishing agents, steel (KSD3512 SCP1), brass (KSD5201 C2801, KSD5101 C3771), aluminum (KSD6701 A5052P) and stainless steel (KSD3698 STS304) were placed at 38±2℃ for 21 days to reduce weight loss. It was measured and evaluated. The weight loss must be 3 mg / 20 cm 2 or less per day to meet the standard, and all of the fire extinguishing agents of the present invention were found to meet the corrosiveness standard.
