| I.P Abstract & Summary |
FIELD: fire-fighting equipment. SUBSTANCE: present invention relates to a multifunctional spontaneous ignition inhibitor for bituminous coal in form of a foaming concentrate. Described is a multifunctional spontaneous ignition inhibitor, obtained in the form of a foaming concentrate, which is configured so that it is sprayed together with water and air and distributed and applied on bituminous coal in a foamed state, wherein the spontaneous combustion inhibitor is obtained by mixing 7–13 wt. % of the antioxidant, 20–40 wt. % of a volatile substance activation inhibitor, 20–40 wt. % of an emulsifying composition and 20–40 wt. % of water, wherein the antioxidant contains phenylenediamine, the volatile substance activation inhibitor contains methyldiethanolamine (MDEA), emulsifying composition contains 25–40 wt. % of butyl diglycol, 2–10 wt. % of glycol ether, 3–10 wt. % of non-ionic surfactant and 45–65 wt. % of emulsifier based on castor oil. |
