근본적인 소화기의 개념 정리!!
소화기의 형식 승인을 떠나서, 근본적인 소화기의 개념 정리!!

1. 수동식 소화기 : 화재 발생시 초기 진압용

따라서 화재가 크게 번졌을 때는 수동식 분말(하론, Co2등 어떤 것도)소화기는 화재 진압을 못 합니다,,, 요즈음 모든 실내 장식 및 음식 조리 기구가 가스 및 플라스틱으로 이루어 져있어서, 화재가 일단 번지면, 대책이 잘 안 섭니다,,,,
수동식 소화기를 비치하는 것은 초기 화재(즉, 주위의 온도가 섭씨 65도<이것은 스프링클러가 작동 되는 온도이며, 화재가 발생되였다는 증거 입니다>진압용 임을 선결 조건으로 생각하면, 수동식 소화기가 고온에서 견디 거나, 섭씨 100도 이상 혹은 과중한 압력 또는 충격압력(뭐 소화기로 무기로 쓴다면 할 수 없지만, 소화기에 무슨 놈의 충격이 가하여 진다고 가정을 하여, 튼튼하게 만듭니까?
소화기를 집어 던져서 안 깨여 지거나, 떨어 뜨려서 터지지 않을 정도의 압력 및 충격 강도를 가지면 되지, 무슨 이 놈의 소화기가 귀중품도 아니고, 화재를 완전히 진압할 수있는 소방 차도 아닌데,,,, 요즈음 간이 소화용구(예를 들면, 스프레이 소화기<삼우 산기의 Fire Killer, tyco의 pyroChem, 홍익 상사의 스프레이 식 하론 Firejet, 부산 SYK의 Fire119, Perfect Korea의 KO-Fire, Fire And Tech의 Fire Cut(불뚝), 기타 등등의 청정 소화약재(일단은 분사하여도 공해 물질이 아니고, 환경 친화적인 약재로 되여야만 합니다, 즉, 하론 이나 Co2같은 공해 물질이거나, 위험 물질로서는 스프레이 소화기(엄격히 말하면, 소화용구)를 만들거나, 팔 수도 없는 실정입니다(형식 승인도 물론 안 내 줄거고요,,,,)

Polycarbonate Cylinder*™*(PC)™

Polycarbonate Cylinder*TM* for Pressure-Containers
can be used for Fire Extinguishers, Aerosol Sprays for insect killers, Hair Sprays or Topics and also for Spray(Aerosol) Types of Fire Extinguishers;

Main Characteristics of Polycarbonate:
a. Transparent/Nude/Visible/Clean
b. Strong enough for +140C -60C
c. Weather-resistant
d. Impact-Resistant
e. Heat-Resistant
f. UV Sustainable
g. Engineering Plastics from GE, Dow-Chemical, Buyer
h. Tested in Aero-spaces by Astronaut Mr. Amstrong in the Moon.
i. Newly improved by Lexan Calibre and Mikatron

Applications:
1. Fire Extinguishers, Dry Chemical or Wet Chemicals
2. Pressure-Containers, replacing Aluminum or Steel Cans, for Insect Killers or Hair Sprays/Topics
3. Cooking Gas(Butan or LPG) Containers instead of Steel cans
4. Spray types of Fire Extinguishers,
containing Halon, AFFF, Dry Chemicals or Liquids(Reinforced Surffectants)
5. Any Other application without Pressure Containing

Other Chemical properties of PC;
1) Impact strength: The impact strength of solid PC sheets is 250 times
that of glass, and the impact strength of hollow PC sheets is 80 times
that of glass
2) Light weight: the weight of a solid PC sheet is only about half of
glass, and the weight of a hollow PC sheet is only about one twelfth
at the same thickness
3) Transparency: The light transmission of a 3mm solid PC sheet is 88%,
and the light transmission of a6mm hollow PC sheet is 80%
4) UV-protection: A PC sheet is co-extruded with a high-density ultra
violet ray that also keeps the PC sheet from discoloring
5) Resistance to weather: A PC sheet has resistance to bad weather and
maintains excellent properties in a wide temperature range from -40
to 120oC
6) Inhibiting condensation: When the outdoor temperature is 0oC
and the indoor temperature is 23oC, the PC sheet will be
condensation up to 80% humidity
7) Thermal insulation: The K-value of glass is 1.2 times that of solid
a PC sheet and is 1.7 times that of a hollow PC sheet. PC sheets
saves energy while preventing heat loss
Sound insulation: The hollow form and polycarbonate resin offers
significant advantage to that of glass
9) Flame Resistance: Through testing by the National Center for Quality
Supervision & Testing of Fire Building Materials, the material is
rated as Class B1 according to QB8624-1997 standards
10) Easy installation: A PC sheet can be bent while hot or cold and can
be used on curved roves and windows. The minimum radius of curvature
of a PC sheet is 175 times of its thickness.
