Abstract

The invention discloses a general A-type foam extinguishing agent easy to degrade. The general A-type foam extinguishing agent easy to degrade comprises the following components in parts by weight: 8%-25% of main foaming agents, 5%-20% of auxiliary foaming agents, 20%-40% of cosolvents, 0.1%-5% of foam stabilizers and the balance of water, and also comprises a proper amount of wetting penetrating agents, corrosion inhibitors and preservatives. The foam extinguishing agent has the characteristics of excellent fire extinguishing, heat-insulation protection performance and low toxicity, and can be used for rapidly fighting commonly-seen solid fire and liquid fire.

Description

technical field [0001] The invention belongs to fire extinguishing agents, in particular to a general-purpose easily degradable Class A foam fire extinguishing agent. Background technique: [0002] Foam fire extinguishing agent is a kind of fire extinguishing equipment mainly used to extinguish various solid and liquid fires. It plays an important role in ensuring the safety of people's lives and property. Class A foam fire extinguishing agent is mainly used to extinguish solid fires. [0003] It has been reported that fully foamed Class A foam fire extinguishing agent foam is sprayed on the building, and the air pockets in the accumulated bubbles can be used to block the heat radiation of the external fire source, thereby preventing the building from being blocked by adjacent burning buildings. ignition, but in order to achieve this thermal protection effect, the foam needs to have a high degree of stability and a high expansion ratio. In addition, at present, Class A foam...
