🔥 Alkaline Fire Extinguishing Foam Gel – Production, Formulation and Properties
Overview:
Alkaline Fire Extinguishing Foam Gels are advanced firefighting formulations designed for industrial, metal, and hydrocarbon fires where strong cleaning, neutralizing, and cooling properties are required.
These gels form a dense, heat-resistant foam blanket that suppresses flames, isolates oxygen, and prevents re-ignition by neutralizing acidic residues.
With a pH range between 8 and 10, they are particularly effective in environments where corrosive or chemical fires may occur, such as automotive plants, machine workshops, and chemical factories.
Production and Formulation:
Production of alkaline fire extinguishing foam gels involves careful blending of surfactants, stabilizers, alkalis, and thickening agents under moderate agitation to achieve a homogeneous and stable product.
The process typically includes:
-
Aqueous Base Preparation: Water is charged into a reactor and alkalis are slowly dissolved to reach the desired pH level.
-
Surfactant Incorporation: Biodegradable or synthetic foaming agents are added to create stable, expansive foam.
-
Stabilizer Addition: Foam stabilizers and emulsifiers are introduced to improve heat resistance and film integrity.
-
Viscosity Adjustment: Thickeners are added to create a gel structure with strong adhesion to metal and vertical surfaces.
-
Homogenization and Cooling: The mixture is stirred until uniform, clear, and ready for packaging.
