Description
Technical field
The present invention relates to a kind of extinguishing chemical, especially a kind of preparation method of non-fusibility aqueous film-forming foam extinguishing agent belongs to
Extinguishing chemical preparation technical field.
Background technique
Currently, environmental pollution aggravates increasingly, atmospheric ozone layer is seriously damaged, and " breathing out dragon " extinguishing chemical is to destroy ozone layer
Chief culprit；In the extinguishing chemical for putting out oil fire, aqueous film-forming foam extinguishing agent is dual due to its MJPZ and foam
Fire extinguishing effect has best extinguishing effect.And since ingredients most in aqueous film-forming foam extinguishing agent are water, in international model
As the ideal substitute of halon fire agent in " the cancelling system action " enclosed, become the extinguishing chemical given priority in the world.
Fluorinated surfactant aqueous solution of the principle of aqueous film-forming foam extinguishing agent based on very low concentrations can be in the paving on pasta
Exhibition.Fc-surfactant is the hydrogen moiety or complete in conventional surfactants (hc-surfactant) molecule hydrocarbon chain
Portion's fluorine atom replaces a kind of special surfactant to be formed, and is surface-active highest one in current all surface activating agent
Class, property most outstanding first is that it the surface tension of water can be dropped to it is very low so that aqueous solution can be in pasta upper berth spread
At water membrane.It is this can pasta upper berth spread at the fc-surfactant aqueous solution of moisture film be commonly called as " light-water ".If
Foam, as aqueous film-forming foam extinguishing agent (or " light-water " fire foam) is made in " light-water ".
Non-fusibility aqueous film-forming foam (AFFF/AR) extinguishing chemical increases non-fusibility on the basis of aqueous film-forming foam extinguishing agent
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 completely cuts off the contact of 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.It is widely used in fighting various types B class fire, extinguishing property has go out oils and the stone of aqueous film-forming foam extinguishing agent
Outside oil product substance fire characteristics, and fighting alcohol, paint, alcohol, ester, ether, aldehyde, ketone, amine with water-resistant foam extinguishing chemical
Isopolarity solvent and water-soluble substances fire characteristics.It can simplify and save not well-known or have oils concurrently and polar solvent mixes
B class A fuel A fire, 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.
