MT/2	MT/3	MT/5

Product Introduce
Our company produces MT/2, MT/3 and MT/5 dioxide fire extinguisher ,which defers to the GB4351-2005 standard, the casing of body made of the high quality alloy steel after the special processing, the weight reduces 40% than the carbon steel. operation safely, reliable, easy to storage, Facile artistic

The fire fighting principle and the application method
1 The principle of fighting fire: When fire extinguisher bottle in storing liquid carbon dioxide, working, press down valve handle .
The carbon dioxide achieved when enough density the flame can suffocate extinguishes, because simultaneously the liquid carbon dioxide can gasify rapidly, in very short time inner absorption massive quantity of heats, therefore certain cooling effect to burning, also is helpful to the fire fighting.
2 Application method: Take the fire extinguisher to the fire scene, pulling out theinsurance pin, grips tightly the hose, press down the presseing handle,aim at flame base to spray; Loose the handle, may stop spraying, thus gap spraying.

The maintenance and attention

1. The fire extinguisher should lay aside in the dry non-corrosiveness gas place, also does not have the fire to roast, to explode exposes to the sun with the collision.
2. The periodic inspection fire extinguisher’s weight every half year, lower than the fixed sufficient load 5%, sho uld deliver intelligence service department to overhaul gasifies again.
3. The fire extinguisher opens, even if the blowout are not much, leaves must be filled again according to the request. Filled should be done by the specialized service department according to the factory request and the method, do not change the fire-extinguishing variety and weight.
4. The fire extinguisher expires for five years, each later two years, its major component, likethe tube body and so on will be supposed to carry on the hydraulic pressure test according to the standard, the hydraulic pressure test pressure is 25MPa, will be supposed to determine the remaining strain rate while hydraulic pressure test, it will not be worth being bigger than 6%.After the experiment should get the experiment in the fire extinguisher tube body shoulder years and the experiment unit code.
5. The fire extinguisher which repaired by the service department, should have the fire prevention to supervise the mark which the department approves, and indicates the service unit name and the service date; Refer the maintenance handbook.
6. Fire extinguisher storing temperature: -10℃～+45℃。
7. The warranty period is a year. While complete in the lead sealing, the safety pin has not moved and in the storage and transportation reasonable situation, if the air leakage, is responsible by the company to repair.

The applicable scope
Carbon dioxide fire extinguisher is one kind of cleanest fire extinguisher, he cannot cause the pollution to the scene of a fire environment, does not corrode in the scene of a fire the instrumentation equipment and the valuables, after the fire fighting without the scar, For the flammable fluid or in catches fire solid, the gas and the electric appliance equipment fire which under the condition may liquefy.Uses in the industry and mining enterprise matching the substation, the ships engine compartment generally and so on, is suitable in savesthe precise electronic instrumentation and the precious equipment fire.
