Abstract

Abstract The superfine dry powder fire extinguishing agent has the characteristics of high fire extinguishing efficiency and low cost and has been widely used in the field of fire extinguishing. This paper briefly describes the classification and current problems of dry powder and analyzes the current technology of micronization and surface modification. The superfine dry powder fire extinguishing agent is greatly improved in water resistance by surface grafting modification, the water repellency meets the standard requirements, and the D90 particle size of the dry powder extinguishing agent after modification is ≤15μm.
