The high-expansion foam fire extinguishing agent is a general-purpose synthetic foam fire extinguishing agent of high and medium expansion, which is made up of foaming agent, cosolvent, stabilizer, antifreeze and water.
The main fire extinguishing effect of high expansion foam is inhibition. When the foam is supplied to the fire point, the foam is easily destroyed, so that the moisture starts to vaporize. The high-expansion foam can cover the entire flame area when the foam is supplied, and the water vapor saturated with the foam liquid agent forms an oxygen-poor area, thereby reducing the combustion speed and stopping the combustion. Another performance of high-expansion foam is its thermal insulation performance and its ability to prevent fire from spreading to nearby combustibles.
Product composition of high expansion foam fire extinguishing agent
3%G 6%G high expansion foam fire extinguishing agent (formerly YEG-3, YEG-6 type high expansion foam fire extinguishing agent). It is made by adding a small amount of foam stabilizer, antifreeze, solvent and other raw materials with composite surfactant as foaming agent. It has the characteristics of good seawater resistance, high foaming ratio, strong sealing, and quick recovery of the working environment after fire extinguishing. It relies on a lot of foam to sensitively cover the burning material or cover the protected space, and save life with the dual effects of suffocation and cooling. It is mainly used for Class A fires (such as wood products, fiber products, coal, etc.) in limited spaces such as underground tunnels, hangars, ship warehouses, warehouses, and basements, and can also compensate for large-area oil fires. This product is not suitable for making up water-soluble flammable liquid fires such as alcohol, ether, aldehyde, ketone, etc. According to the volume mixing ratio with fresh water or sea water, there are two types: 3%G type (3:97) and 6%G type (6:94). The shelf life is 3 years.
Application scope of high expansion foam fire extinguishing agent
The fire extinguishing agent is a general-purpose synthetic foam fire extinguishing agent of high and medium expansion, which can be applied to various types of high and medium expansion foam generators. It is widely used in underground tunnels, hangars, underground oil depots, garages, ships, coal mines and other limited spaces for fire prevention and rescue. It is used to cover large areas of non-water-soluble flammable, combustible and dispersible liquids, and can play its role.
