摘要:
A fire fighting foam composition is disclosed comprising water and diutan gum; and either one or more nonionic surfactants with one or more water-miscible organic solvents and with such composition comprising less than 0.35% by weight of a fluorinated surfactant; or an alkyl polyglycoside with one or more anionic surfactants and one or more glycol solvents and with such composition being substantially free of fluorinated surfactants.
摘要:
The object of the present invention is to provide a fire extinguishing agent that can extinguish fire and check the spread of fire by easily containing water therein by means of heat due to the fire and solidifying thereby adhering to a burning object; a fire extinguishing water and a method for extinguishing fire by using it. Concretely, the present invention relates to a fire extinguishing agent comprising a thermosensitive polymer that is water-soluble at a temperature not more than a specific preset temperature and that gels or solidifies by containing water therein by means of heat due to a fire which attains to a temperature not less than the preset temperature; a fire extinguishing water obtained by dissolving the fire extinguishing agent into water optionally with a flameproofing agent or other fire extinguishing fire agent; and a method for extinguishing fire using the fire extinguishing water.
摘要:
The fire fighting and hot surface cooling methods of this invention use a composition formed by combining a nonionic surfactant possessing a specific photoexcitable functional group with an arylphosphate, also of photoexcitable nature, in a solvent medium of composition and content that allows for a convenient workable viscosity and is resistant to effects of freezing. The ultimate water solution used for spraying to extinguish a fire or cool a surface contains from 2000 ppm of the surfactant nonylphenolethoxylate and 94 ppm of the arylphosphate, phenol-6-phosphate, to 3000 ppm surfactant and 141 ppm arylphosphate. A nonaqueous composition containing a mixture of different nonylphenolethoxylates to extinguish lithium type fires is also described. The spray solution is applied to the fire until the desired result occurs.
