AI Technical Summary

Problems solved by technology

When the existing dry powder fire extinguishing agent powder is used in a three-dimensional combustion type fire, it is not easy to adhere to the three-dimensional surface of the burning object, and it is easy to fall off or scatter with the help of wind, and the fire extinguishing effect is not good.

Abstract

The invention relates to a fire extinguishing agent for fire protection engineering. The fire extinguishing agent for fire protection engineering comprises 5% of hydrophobic solid particles, 1% of a water-soluble surfactant, 10% of inorganic salt containing crystal water and 7% of acid ester according to the proportion, wherein the mass percent of solute in an aqueous solution is 15%-35%. The fire extinguishing agent for fire protection engineering has the effects of improving the fire extinguishing performance and reducing production cost.

Description

technical field [0001] The invention relates to a fire extinguishing agent for fire engineering. technical background [0002] Fires are usually divided into five categories ABCDE, where A category refers to solid material fires, B category refers to liquid or soluble solid substance fires, C category refers to gas fires, D category refers to metal fires, and E category refers to live fires, that is, objects are charged and burned fire. Therefore, according to the nature and characteristics of various fires, different types of fire extinguishing agents need to be selected. [0003] Dry powder fire extinguishing agent is a commonly used fire extinguishing agent, which has the characteristics of dryness, easy flow, good moisture resistance and anti-caking property, and is widely used in oil fields, oil depots, refineries, chemical plants, chemical warehouses, ships, airports and industrial and mining enterprise. Currently used dry powder fire extinguishing agents are mainly...
