The alcohol-resistant aqueous film-forming foam concentrate (AFFF/AR) is mixed with water in proportion, and can be foamed in various low-expansion foam generating equipment. The generated foam is applied to the surface of alcohol or other polar solvents, which can resist the foam that is destructive to the foam. Liquid, also known as anti-alcohol foam liquid. It can quickly put out fires caused by polar solvents such as alcohols, esters, ethers, ketones, aldehydes, etc., as well as various oil fires. The anti-dissolving water film-forming foam fire extinguishing agent is widely used to extinguish various types of B fires. The general fire extinguishing performance can extinguish unknown or mixed B fuel fires with oil and polar solvents, and unleaded vehicle gasoline. Fire. It is suitable for extinguishing large oil tank fires by "submerged jet", and can be used in combination with dry powder extinguishing agents to extinguish fires, and can be used with most fire-fighting foam extinguishing agents in the process of extinguishing.
