Fire extinguishing agent and fire extinguishing method using same

Abstract

The purpose of the invention is to provide a fire extinguishing agent which has both high fire-extinguishing performance and a high level of safety to the environment and the human body. This fire extinguishing agent is characterized by containing a biosurfactant.

Description

technical field [0001] The invention relates to a fire extinguishing agent containing biosurfactant and a fire extinguishing method using the fire extinguishing agent. Background technique [0002] Tens of thousands of fires occur every year in China alone, which is a major problem for the global environment and human society. In the event of a fire, it is very important to effectively extinguish the fire while minimizing the damage caused by the disaster. However, water or a water-based fire extinguishing agent has been used as a conventional fire extinguishing agent. As a common water-based fire extinguishing agent, there is known a strengthened liquid fire extinguishing agent (potassium carbonate aqueous solution), which reduces the surface tension of water by adding a synthetic surfactant, thereby improving its wetting to combustibles such as wood, fiber, resin, etc. Moisture and permeability, or make it foam to improve adhesion, and can improve the fire extinguishing e...

AI Technical Summary

Problems solved by technology

[0003] However, in addition to these fire extinguishing properties, the safety of fire extinguishing agents for the environment and human body is also a matter of great concern

[0004] For example, the enhanced liquid fire extinguishing agent is effective especially for fires caused by frying oil, but since it exhibits a strong alkalinity of pH 12 to 13, there are problems with respect to the adhesion of the fire extinguishing agent to furniture, tableware, Utensils, etc. need to be carefully cleaned or discarded forcibly, and there is concern about the corrosion of the metal structural framework, doors, windows, partitions, etc. that have not been damaged by fire

In addition, when a fire extinguishing agent using a synthetic surfactant is sprayed, it is highly toxic to aquatic organisms, etc., and due to the spraying of an existing fire extinguishing agent, secondary disasters after fire extinguishing may occur
