Description
Technical field
The present invention relates to fire-fighting fire extinguishing field, especially a kind of tearable membranaceous extinguishing chemical and its using method and equipment.
Background technology
It is well known that with the continuous improvement of people's living standard, household appliances increase day by day, being used with fiery electricity consumption in life
Gas is increasingly frequent, and the incidence rate of family fire also drastically rises.If providing some fire distinguishers at home for oneself, can flutter in time
Go out the little flare of firm combustion gas, prevents the condition of a disaster from spreading.
Water is the most frequently used extinguishing chemical, but fire-fights by water and there are many defects, and such as water has conductivity, it is impossible to be used for
The fire extinguishing of electrical equipment, water also have mobility, object and building is endangered by water stain, and most of water can be along combustion
The surface or gap for burning thing flows away, and extinguishing effect is low.In order to improve fire-fighting efficiency, Chinese patent CN102188781A discloses one
High-temperature phase-transitional temperature-sensitive fire-extinguishing gel is planted, the fire-extinguishing gel is the polyprotic acid and hydrophobic backbone structure of hydrophilic backbone structure
Polyamine in mass ratio 1:3～1:12 ratio is soluble in water to be sufficiently stirred for forming water white transparency liquid, and the wherein quality of water is institute
2～5 times of the polyprotic acid stated and the quality summation of polyamine, the fire-extinguishing gel is by the polyprotic acid of hydrophilic backbone structure and dredges
The gel under water solublity and hot conditionss under cryogenic conditions is realized in the physical crosslinking effect of the polyamine of aqueouss backbone structure
State.The extinguishing chemical is low viscosity water solution at normal temperatures, and viscosity incrementally increases and quickly formed hydrogel after heated, is attached to combustion
Thing surface is burnt, the effect of fire extinguishing is reached and fire spreading can be blocked, liquid is returned to again after gelling temp is down to uniform temperature
State, is rinsed with water and can remove residue.However, the fire-extinguishing gel cleaning trouble, water consumption is big, and is not suitable for going out for electrical equipment
Fire.Although carbon dioxide extinguishing agent can be used for the fire extinguishing of electrical equipment, does not leave spot in collector surface, but which has extinguishing concentration
High, extinguishing grade is low, preferably relatively closed space using, anti-resume combustion ability, easily make one the danger such as asphyxia.As can be seen here,
