Problems solved by technology

The innovation direction of fire extinguishing agent manufacturers has always focused on how to enhance the environmental protection and harmlessness of fire extinguishing agents, the performance of fire extinguishing agents to quickly extinguish open flames, and the stability of fire extinguishing agents. These are indeed important directions for the subsequent development of foam fire extinguishing agents. However, with the occurrence of the diversity of actual fires, it is no longer enough to just stay at the element of quickly extinguishing open flames, such as lithium-ion battery fires, or some fire scenarios that require rapid cooling. Or the temperature of the surface and interior of the burning object may cause the fire to re-ignite, which will lead to missing the best time for fire extinguishing and rescue, which will cause greater possibility of loss of life and property
[0005] Moreover, the foam produced by most foam fire extinguishing agents on the market has good airtightness, but for Class A fires, the foam has poor fluidity and poor cooling ability. To achieve better cooling ability, it is necessary to increase the amount of fire extinguishing agent. There is still a lot of inconvenience in the process of using this
