Problems solved by technology

However, the existing domestic traditional foam fire extinguishing agent is not suitable for this type of fire fighting vehicle, and the price of imported fire extinguishing agent is too high (300,000 yuan / ton), so a kind of fire-fighting water additive suitable for market needs is urgently needed now

Abstract

The invention discloses an additive for firefighting water, which is formed by the following raw materials by weight percent in a mixing way: 5-10 percent of fluorocarbon surfactant, 40-50 percent of foaming agent, 3-10 percent of penetrating agent, 5-10 percent of fire retardant, 3-5 percent of burn-resistant agent, 5-10 percent of antifreeze agent, 3-5 percent of booster solvent, 0.3-2 percent of pH regulating agent and the remaining percent of purified water. The highly-enriched water additive can be mixed with water by any proportion within 0.1-6 percent, and is suitable for the existing firefighting trucks in the market, novel firefighting trucks and water-based firefighting systems. When in extinguishing Class A fires, only 0.1-0.5 percent of additive is added and good permeability and abundant foam can be produced. Moreover, the additive is suitable for foaming systems and spray equipment. For non-water-soluble Class B fires, the required concentration of the used additive is only one percent and good effect can be reached. For water-soluble Class B fires, the concentration of the used additive is 3-6 percent. The used additive causes no environmental pollution and thereby the additive is environment-friendly.

Description

technical field [0001] The invention relates to an additive for fire fighting water, which has the characteristics of high concentration, low mixing ratio of agent water and high efficiency, and is mainly used for fighting A and B class fires. Background technique [0002] The water additives for fire fighting at home and abroad are mainly foam fire extinguishing agents, and water film-forming foam fire extinguishing agents (AFFF for short), protein (P) and fluoroprotein (FP) are mainly used. The surface is extended to cover and isolate the air, so as to quickly extinguish the fire. The relevant information released by the Ministry of Public Security shows that the concentrations of foam fire extinguishing agents produced at home and abroad are 3% and 6% respectively; With the continuous decommissioning, most of the new fire fighting vehicles imported from abroad (such as No. 17 fire fighting vehicles) were replaced, and some of them were new fire fighting vehicles independ...
