Industrial-grade Sodium Bicarbonate is a versatile basic chemical whose value is fully realized in areas such as chemical reagents and fire extinguisher raw materials. In chemical laboratories and industrial production, it serves as a mild alkaline agent widely used for neutralizing accidental acid spills, treating acidic wastewater, and acting as a pH regulator or carbon dioxide source in chemical synthesis. For example, in the production of dye intermediates, pesticides, or certain fine chemicals, it provides a safe and controllable alkaline environment. However, one of its most prominent applications is as the core component of dry chemical fire extinguishing agents. BC-class dry powder agents typically consist of sodium bicarbonate (often over 90%), combined with hydrophobic agents, anti-caking agents, etc., through specialized mixing processes. Its extinguishing mechanism is primarily based on chemical inhibition: when the powder is discharged into a flame, the heat causes sodium bicarbonate to rapidly decompose, producing carbon dioxide and water vapor, which instantly dilute the flammable gas concentration. More importantly, the active sodium ions generated from decomposition undergo gas-phase reactions with hydroxyl (OH•) and hydrogen (H•) radicals present in the combustion chain reaction. This effectively captures and consumes these high-energy radicals, thereby interrupting the vigorous chain reaction of combustion and achieving rapid fire suppression. This type of extinguisher is particularly effective against Class B (flammable liquids, e.g., oils, solvents) and Class C (flammable gases, e.g., LPG, natural gas) fires. Our industrial-grade sodium bicarbonate product undergoes strict particle size control to ensure flowability, dispersibility, and reaction efficiency in flames, and it exhibits good compatibility with other additives in fire extinguishing formulations. We can stably supply high-quality raw materials that meet relevant industry standards to manufacturers of firefighting equipment, ensuring the reliability and effectiveness of the end-use fire safety products.
