【発明の詳細な説明】
（産業上の利用分野）
この発明は、軟質のゼラチンシートに消火剤を収容した
軟カプセル消火剤に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a soft capsule fire extinguisher containing a fire extinguisher in a soft gelatin sheet.
（従来の技術）
粉末消火剤は、燐酸アンモニウム、炭酸水素ナトリウム
、炭酸水素カリウムなどを粉砕して微粉末とし、粉末が
固化しないようにその表面にシリコーンコーティングを
施している。そして一般にその粉末の粒径は４４ｕ−の
ものが２０〜８０％含まれている微粉末である。これは
微粉末でないと所定の消火能力がえられないからである
。(Prior Art) Powder fire extinguishers are made by crushing ammonium phosphate, sodium hydrogen carbonate, potassium hydrogen carbonate, etc. into fine powder, and applying a silicone coating to the surface of the powder to prevent it from solidifying. Generally, the powder is a fine powder containing 20 to 80% of 44u- particles. This is because the specified fire extinguishing ability cannot be obtained unless it is a fine powder.
（発明が解決しようとする問題点）
消火剤がこのように微粉末であると、消火装置のノズル
から火災現場まで到達する問に、風によって飛ばされる
ことが多く、消火に有効に使用されない、また液体消火
剤でも蒸発しやすい例えばハロン２４０２などの消火液
では、放射射程中で飛散蒸発するので粉末消火剤と同様
の結果となる。(Problems to be Solved by the Invention) When the extinguishing agent is such a fine powder, it is often blown away by the wind when it reaches the fire scene from the nozzle of the fire extinguishing system, so it cannot be used effectively for extinguishing a fire. Furthermore, even liquid extinguishing agents tend to evaporate, such as Halon 2402, which scatters and evaporates within the radiation range, resulting in the same results as dry extinguishing agents.
また粉末消火剤は吸湿しやすい性質があるので、消火装
置等の容器に長期間収容して置く問に吸湿固化し使用出
来ないことがある。Furthermore, powder fire extinguishing agents tend to absorb moisture, so if they are stored in containers such as fire extinguishing equipment for a long period of time, they may absorb moisture and harden, making them unusable.
この発明は、上述する欠点に鑑み、消火剤本体の粒径、
組成などの姿態を変えず、大きな粒に形成した消火剤を
所定の火災現場まで確実に到達させ、火災の熱でその粒
が破壊し所定の消火能力を発揮する消火剤を得ること、
そして長期間の貯蔵に固化等変質の生じない消火剤を提
供するものである。In view of the above-mentioned drawbacks, this invention has been developed to reduce the particle size of the extinguishing agent body,
To ensure that a fire extinguishing agent formed into large particles reaches a designated fire site without changing its appearance such as composition, and to obtain a fire extinguishing agent that exhibits the prescribed fire extinguishing ability by destroying the particles with the heat of the fire.
The present invention also provides a fire extinguishing agent that does not undergo deterioration such as solidification during long-term storage.
（問題点を解決するための手段）
この発明はすなわち、ゼラチン基質のシート間に粉末、
液体、あるいはこれらの混合物よりなる消火剤を収容し
カプセル化したことを特徴とする軟カプセル消火剤であ
る。(Means for Solving the Problems) In other words, the present invention provides powder between sheets of gelatin substrate.
This is a soft capsule fire extinguishing agent characterized by containing and encapsulating a liquid extinguishing agent or a mixture thereof.
一般に軟カプセルは、周面にカプセル形を凹部に形成し
た二つのローラーが狭い除閉をもって相対して逆転し、
それぞれのローラーに別に作ったゼラチンシートを誘導
し、二つのローラーで圧着する間に薬剤の噴射ノズルよ
り二つのシートの凹部に薬剤を入れ、その後カプセル部
を打ち抜きカプセルとしている。In general, a soft capsule has two rollers with a capsule-shaped recess formed on the circumference that rotates opposite each other with a narrow opening and closing.
Separately made gelatin sheets are guided to each roller, and while the two rollers are pressing them together, a drug is injected into the recesses of the two sheets from a drug injection nozzle, and the capsule portions are then punched out to form capsules.
粉末消火剤には従来使用されている燐酸アンモニウム、
炭酸水素ナトリウム、炭酸水素カリウムなどの消火剤を
収容する。これらの消火剤は従来使用している粉体の表
面にコーティングを施したもの、または施さないものど
ちらも使用できる。Ammonium phosphate, which is traditionally used as a powder fire extinguisher,
Contains fire extinguishing agents such as sodium bicarbonate and potassium bicarbonate. These fire extinguishing agents can be used in the form of conventionally used powders with or without a coating on the surface.
いずれもカプセルのゼラチン質に影響を与えず、長期間
カプセルの内部で変質固化しない。Both do not affect the gelatin quality of the capsule and do not deteriorate or harden inside the capsule for a long period of time.
液体の消火液としては、カプセルのゼラチン質に影響を
与えないハロン２４０２が良い。As a liquid fire extinguishing liquid, Halon 2402, which does not affect the gelatin of the capsule, is preferred.
（作用）
軟カプセル消火剤は従来用いられている窒素ガスなどの
高圧ガスとノズル装置で放射できる。この消火剤の粒は
その径が大きいので風の・影響を受けること少なく火災
現場まで飛び消火する６そして消火剤は火災の熱に会い
、カプセルの殻が熱で溶けて内部の消火剤が飛散し消火
する。またカプセル内の空気が火災の熱で膨張しカプセ
ルは破裂して内部の消火剤が飛散し消火する。(Operation) Soft capsule extinguishing agents can be emitted using conventionally used high-pressure gas such as nitrogen gas and a nozzle device. The particles of this extinguishing agent have a large diameter, so they are not affected by wind and fly to the fire site, extinguishing the fire6.Then, the extinguishing agent meets the heat of the fire, the shell of the capsule melts with the heat, and the extinguishing agent inside is scattered. and extinguish the fire. In addition, the air inside the capsule expands due to the heat of the fire, causing the capsule to rupture and the extinguishing agent inside to scatter and extinguish the fire.
