Usage of Heptafluoropropane
Heptafluoropropane(HFC-227ea)is a kind of chemical way and clean gas extingushing agent,its colorless, flavourless, innocuous, nonconducting. And will not pollute the object to be guarded.In particular will not destory atmospheric ozone layer,(0DP value is zero)accord with the environmental requirement,it is halon extingguishing agent perfect surrenal at present stage.This kinds of fire extinguishingagent have thecharacteristic of high efficiency in outfire,high speed,have no secondary pollution,can out fire like this kinds of area:
(1)safeguard include valuables,priceless treasure,or the firm important date and soft hardwar device and etc....;
(2)The device where have no automatic sprinkler system or the device will dmage by water;
(3)The area where people regularity live in;
(4)The area where it's hard to clean after eject medicament;
(5)Medicament steel cylinder space is limited,a small amount evtinguishing medium can put out the fire;
(6)The object to be guarded is electric equipment,must use the non-conductive extinguishing medium.
Packing:
Filled in cylinders, each 1000kg net. Its category of dangerous goods is 2.2, and its packing category is second grade.
- Q:Is the dry powder in the dry powder extinguisher harmful to the human body?
- The dry powder fire extinguisher uses carbon dioxide gas or hydrogen gas as motive power to spray dry powder out of the fire. Dry powder is a dry, easy to flow fine solid powder. It can be composed of base material and moisture proof agent, flow enhancer, caking agent and anti - additive. It is harmless to human body. This is non-toxic
- Q:Should dry powder extinguishers be pressurized in a few years?
- Daily inspection of dry powder extinguisher includes pressure check, normal in green area, red area is under pressure, must be re loaded, in yellow area is over pressure, over pressure is not too serious can be used.
- Q:What's the difference between a dry fire extinguisher and a 2 carbon dioxide extinguisher?
- Carbon dioxide fire extinguisher mainly depends on the action of carbon dioxide suffocation and partial cooling. Extinguish fire from books, archives, precious equipment, precision instruments, electrical equipment and oils under 600 volts. Use well in the dust proof area.
- Q:Where dry powder fire extinguisher?
- . Such as sodium bicarbonate dry powder, modified sodium salt powder, potassium salt dry powder, phosphoric acid two ammonium hydrogen dry powder, diammonium phosphate dry powder, phosphoric acid dry powder and amino powder fire extinguishing agent, etc.. Dry powder extinguishing agent mainly through under the action of pressurized gas sprayed powder and mixed flame contact, occurs when the physical and chemical action: one is to rely on the inorganic salt powder volatile decomposition, and fuel combustion in the process of free radicals or reactive group chemical inhibition and side catalytic effect, the the interruption of the chain reaction of combustion fire; two is in the combustible surface by dry powder, chemical reaction, and the formation of a layer of high temperature glass layer to isolate oxygen, then smothering. There is also partial dilution of oxygen and cooling action.
- Q:What is the maximum pressure that a dry fire extinguisher can bear?
- The dry powder fire extinguisher is provided with a dry powder extinguishing agent such as ammonium phosphate, which is easy to flow and dry, and is composed of inorganic salt and a grinding dry additive, so that the fire extinguishing agent can effectively save the initial fire.
- Q:What kinds of fire extinguishers should be used in electrical equipment fire?
- Be careful not to use acid base or foam extinguisher, because the fire extinguishing liquor has electric conductivity, and the person who holds the fire extinguisher will get an electric shock. This solution strongly corrodes the electrical equipment and is not easily removed afterwards.
- Q:Has the dry fire extinguisher done any damage to the environment?
- The characteristics of fire suppression, such as suffocation, cooling and chemical inhibition of flame burning, are the concentrated expression of extinguishing efficiency of dry powder, in which chemical inhibition is the basic principle of extinguishing fire and plays a major role in extinguishing fire. Dry powder fire extinguishing agent in the fire fighting group is an inactive substance of the combustion reaction when it enters into the combustion zone in the flame, and the free radical generated by the decomposition of the combustion flame produced in the reaction of H and OH and other free radicals react with each other, capture and termination of combustion reaction of free radicals, reducing the rate of combustion reaction. When the concentration of dry powder in the flame is high enough, and the contact area of the flame is large enough, and the rate of free radical stopping is greater than the rate of combustion reaction, the chain combustion reaction is terminated, thus the flame is extinguished. Dry powder extinguishing agent absorbs heat in burning flame and decomposes, because each decomposition reaction is endothermic reaction, so it has better cooling action. In addition, two high temperature decomposition of ammonium hydrogen phosphate, generating glass layer covers on the surface of residues in the solid surface, prevent combustion, and to prevent the resurgence of.
- Q:What are the 3 colors of a fire extinguisher pressure meter?
- Domestic fire extinguishers generally pressure gauges are divided into three grades, both three colors. When the pressure gauge pointer to red, indicating the pressure in the bottle is not enough, not the normal use of fire extinguishers; refers to the yellow part when the pressure is too large, prone to danger, that the fire extinguisher refers to the green part of the normal
- Q:Does anyone know where the powder extinguisher works?
- Two to the East, northbound seems to have, or may be a little west, where the fire extinguisher to buy, and he said that the place can add powder.
- Q:The difference between dry powder fire extinguisher and 1211 fire extinguisher
- Dry powder fire extinguishing agent is divided into BC powder extinguishing agent (sodium bicarbonate) and ABC powder (ammonium phosphate) two categories. One is to rely on the inorganic salt powder volatile decomposition products, chemical inhibition and side catalysis and fuel combustion in the process of free radicals or reactive groups, the chain reaction of combustion interruption the two is on fire; combustible surface by dry powder, chemical reaction, and the formation of a layer of high temperature glass layer to isolate oxygen, and suffocate the fire. In addition, there are some oxygen dilution and cooling effect.
