What is the difference between a fire extinguisher msj900 and a msj900b?
Type A: a fire that burns solid fuels, including wood, cloth, rubber, paper, and certain plastics.Type B: burning liquid or liquefied fuel, including oil, gasoline, oil, paint, some wax and plastics, but not cooking fats and oils.Type C: fires that burn gaseous fuels, including natural gas, hydrogen, propane, and butane.Type D: a fire that burns metals, including sodium, magnesium, and potassium.Type E: any fire of type A or B, which occurs next to an electric appliance, wire, or any charged body. Control of fire can not use any conductive object, otherwise it may be electric shock.Type F: a fire that burns fats and oils for cooking. Since the temperature is often much higher than that of other B types, fire extinguishers are generally ineffective.
This type of extinguisher belongs to the physical fire extinguishing mechanism. The medicament can form and extend a thin water film on the surface of the combustible material, so that the combustible material can be separated from the air and the fire extinguishing can be realized. The atomizing nozzle, spray water mist, fire and diffuse the heat of evaporation, quickly lower the temperature, the concentration of oxygen in air combustion zone decreases at the same time, to prevent the resurgence of. Anti recrudescence is good, is a big advantage for powder extinguishing There is nothing comparable to this.
Different manufacturers produced MSJ900 series of fire extinguishers may have a little difference, and the suffix B should be the product of raw materials, generally divided into stainless steel and carbon steel two, B for stainless steel, G for carbon steel.
MSJ900 and MSJ900B are water type fire extinguishers, also known as water-based fire extinguishers
