Ingredients Biogenic polysaccharide, when being ejected into the oils or polar solvent of burning, foam can be rapidly in oils or polar solvent surface
Flowing scatters and to the regional diffusion being not yet directly injected to, and forms one layer of closure very in oils or polar solvent surface
Good moisture film, the contact of isolation oils or polar solvent with air.Anti- melt into point in foam, can effectively prevent water-soluble solvent
The moisture in foam is absorbed, to protect foam.Double action by foam and protective film stamps out a fire, and the scene of improving is gone out
The efficiency of fire.Be widely used in various types B class fire of putting out a fire to save life and property, extinguishing property have water-resistant foam extinguishing chemical alcohol of putting out a fire to save life and property,
Paint, alcohol, ester, ether, aldehyde, ketone, amine isopolarity solvent and water-soluble substances fire characteristics, can simplify put out a fire to save life and property it is not well-known or simultaneous
There is the B class A fuel A fire that oils and polar solvent mix, therefore there is general fire extinguishing.
The traditional extinguishing chemical in China in production and use due to generating mercaptan, thioether and sulfureted hydrogen foul gas, meanwhile,
Such product energy consumption, water consumption height are produced, environmental pollution is caused；Therefore it provides one kind reduces environmental pollution, and can effectively flutter
The extinguishing chemical of fire fighting calamity has great importance.
