Description
Technical field
The present invention relates to fire-fighting fire extinguishing field, especially a kind of tearable membranaceous extinguishing chemical and its application method and equipment.
Background technique
It is well known that being used with fiery electricity consumption in life with the continuous improvement of people's living standards, household appliances increase day by day
Gas is increasingly frequent, and the incidence of family fire also sharply rises.If providing some fire distinguishers for oneself at home, can flutter in time
Go out the small flare of rigid combustion gas, prevents the condition of a disaster from spreading.
Water is most common extinguishing chemical, but is fire-fighted by water there are many defects, such as water has conductibility, it is impossible to be used in
The fire extinguishing of electric appliance, water also have mobility, are easy to make object and building by water stain harm, and most of water can be along combustion
The surface or gap for burning object flow away, and extinguishing effect is low.In order to improve fire-fighting efficiency, Chinese patent CN102188781A discloses one
Kind high-temperature phase-transitional temperature-sensitive fire-extinguishing gel, the fire-extinguishing gel are the polyacid and hydrophobic backbone structure of hydrophilic backbone structure
The polyamine ratio of 1:3~1:12 in mass ratio is soluble in water to be sufficiently stirred to form colorless and transparent liquid, and wherein the quality of water is institute
2~5 times of the quality summation of the polyacid and polyamine stated, the fire-extinguishing gel pass through the polyacid of hydrophilic backbone structure and dredge
The water solubility under cryogenic conditions and the gel under hot conditions are realized in the physical crosslinking effect of the polyamine of aqueous backbone structure
State.The extinguishing chemical is low viscosity water solution at normal temperature, and viscosity incrementally increases and quickly forms hydrogel after heated, is attached to combustion
Object surface is burnt, achievees the effect that fire extinguishing and fire spreading can be blocked, is restored to liquid again after gelling temp is down to certain temperature
State, residue can be removed by being rinsed with water.However, fire-extinguishing gel cleaning trouble, water consumption is big, and is not suitable for going out for electric appliance
Fire.Although carbon dioxide extinguishing agent can be used for the fire extinguishing of electric appliance, do not leave spot in collector surface, but its there are extinguishing concentrations
It is high, extinguishing grade is low, preferably in the danger such as relatively closed space uses, anti-re-ignition ability is poor, easily makes one to suffocate.It can be seen that
That there are fire-fighting efficiencies is low for existing extinguishing chemical, easily cause secondary pollution, using it is dangerous, be not suitable for the disadvantages of household electrical appliances are put out a fire.
