Description
Technical field
The present invention relates to the regeneration technology of a kind of expired inefficacy extinguishing chemical, belong to technical field of fire control.
Background technology
AFFF (AFFF) extinguishing chemical is with hc-surfactant and fluorocarbon surfactant for base material can
The fire foam of water membrane is formed on some hydrocarbon liquids surface.This extinguishing chemical can be rapid on hydrocarbon fuels surface
Forming one layer of moisture film that can suppress fuel vaporization the thinnest, this layer of moisture film floats on guiding froth bed on fuel surface, has
Excellent mobility, extinguishing property and anti-resume combustion ability, it is possible to put out a fire quickly and effectively.Even if froth bed is not yet completely covered combustion
Burn liquid or the disrupted place of froth bed, remain able to play the effect stoping resume combustion.
Non-fusibility AFFF (AFFF/AR) extinguishing chemical adds non-fusibility on the basis of aqueous film-forming foam extinguishing agent
Ingredients Biogenic polysaccharide, when being ejected on the oils of burning or polar solvent, foam can be rapidly in oils or polar solvent surface
Flowing is scattered 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, isolation oils or polar solvent contact with air.Anti-melt in foam divides, and can effectively prevent water-soluble solvent
Moisture in absorbing foams, thus protect foam.Dual function by foam and protecting film stamps out a fire, and goes out in the scene of improve
The efficiency of fire.Being widely used in all kinds B class fire of putting out a fire to save life and property, extinguishing property has go out oils and the stone of aqueous film-forming foam extinguishing agent
Outside oil product material fire characteristics, and there is the ethanol of putting out a fire to save life and property of water-resistant foam extinguishing chemical, paint, alcohol, ester, ether, aldehyde, ketone, amine
Polar solvent and water-soluble substances fire characteristics.Can simplify and put out a fire to save life and property the most well-known or have oils concurrently and polar solvent mixes
B class A fuel A fire, therefore there is general fire extinguishing.
Non-fusibility aqueous film-forming foam extinguishing agent should leave in cool place, dry storehouse, prevents from tanning by the sun, the environment temperature of storage
Degree is for-2.5 DEG C～40 DEG C, and storage period is 8 years.Wherein non-fusibility composition effect duration 2 years, after 2 years, non-fusibility composition lost efficacy,
The standard-required being unable to reach qualified products may only be used as aqueous film-forming foam extinguishing agent.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of so that the non-fusibility AFFF after Shi Xiaoing is put out a fire
The activity of agent recovery product carries out the renovation process of the non-fusibility aqueous film-forming foam extinguishing agent of secondary utilization, and passes through the method
The regeneration non-fusibility aqueous film-forming foam extinguishing agent made.
The present invention solves that a kind of technical scheme that above-mentioned technical problem proposes is: a kind of non-fusibility AFFF fire extinguishing
The renovation process of agent, will store more than 2 years and the life of the inefficacy non-fusibility aqueous film-forming foam extinguishing agent mesometamorphism of discontented 8 years
Thing separation of polysaccharides is removed, and is subsequently adding additive, uniformly after mixing, makes reconstituted product；
Described additive includes compounding hc-surfactant, fluorocarbon surfactant, biological polyoses, ethylene glycol, carbamide
And water；
The consumption of described compounding hc-surfactant had lost efficacy non-fusibility aqueous film-forming foam extinguishing agent gross mass described in accounting for
5%～10%, the consumption of described fluorocarbon surfactant account for described in lost efficacy non-fusibility aqueous film-forming foam extinguishing agent gross mass
2%～4%, the consumption of described biological polyoses account for described in lost efficacy the 0.4% of non-fusibility aqueous film-forming foam extinguishing agent gross mass
～0.8%, the consumption of described ethylene glycol account for described in lost efficacy the 5%～10% of non-fusibility aqueous film-forming foam extinguishing agent gross mass,
The consumption of described carbamide had lost efficacy the 3%～5% of non-fusibility aqueous film-forming foam extinguishing agent gross mass described in accounting for, the consumption of described water
The 20%～40% of the non-fusibility that lost efficacy described in accounting for aqueous film-forming foam extinguishing agent gross mass；
Described compounding hc-surfactant be carbon chain lengths be 8 to 10 anion surfactant and carbon chain lengths be
The nonionic surfactant of 8 to 10 is compounding to be formed.
Above-mentioned compounding hc-surfactant is to be mixed by n-octyl sodium sulfate and alkyl glucoside surfactant APG0810
Form.
The compounding mass ratio of above-mentioned n-octyl sodium sulfate and alkyl glucoside surfactant APG0810 is 18 to 15.
The compounding mass ratio of above-mentioned n-octyl sodium sulfate and alkyl glucoside surfactant APG0810 is 16.
Above-mentioned fluorocarbon surfactant includes the fluorine carbon that model is VF-368 fluorocarbon surfactant and model is VF-6116
Surfactant.
The matter that above-mentioned model is VF-368 fluorocarbon surfactant and fluorocarbon surfactant that model is VF-6116 adds
Amount ratio is 11.
Above-mentioned biological polyoses is one or more in xanthan gum, arabic gum, guar gum, Resina persicae, pectin.
The model of the above-mentioned aqueous film-forming foam extinguishing agent of inefficacy non-fusibility is AFFF/AR3% or AFFF/AR6%.
The renovation process of above-mentioned non-fusibility aqueous film-forming foam extinguishing agent uses rectifying column separating technology by the non-fusibility that lost efficacy
The biological polyoses of aqueous film-forming foam extinguishing agent mesometamorphism separates to be removed.
The present invention solves that the another kind of technical scheme that above-mentioned technical problem proposes is: a kind of by above-mentioned renovation process system
The regeneration non-fusibility aqueous film-forming foam extinguishing agent become.
The present invention has a positive effect: the renovation process of the non-fusibility aqueous film-forming foam extinguishing agent of the present invention, main pin
The inefficacy of antagonism soluble components, needs first to be separated by rotten biological polyoses to remove, then selects n-octyl sodium sulfate and alkyl
The compounding hc-surfactant that polyglycoside surfactants APG0810 compounds according to special ratios, is equipped with appropriate fluorine carbon
Surfactant, new biological polyoses is as foam stabiliser, and ethylene glycol is as antifreeze, and carbamide is as solubilizing agent and right
The proportioning of compounding hc-surfactant, fluorocarbon surfactant, foam stabiliser, antifreeze, solubilizing agent and water has been carried out sternly
Lattice control, by new biological polyoses, the performance advantage of specific compounding hc-surfactant and the collaborative effect of other compositions
Should, the product lost efficacy reacted and permeates, so that the product lost efficacy recovers the activity of product again, making
Used time meets the standard-required of GB15308-2006 " fire foam ".The regeneration cost of product is well below purchasing similar product
Product, and save the expense processing expired inefficacy product, efficiently avoid the protection of the waste of resource, beneficially environment.
The reconstituted product of the present invention is mainly used in the prevention of hydrocarbons and water-soluble liquid fire and puts out a fire to save life and property, due in product containing one
Quantitative fluorocarbon surfactant, so product has good mobility, can fuel material surface formed water membrane and
Solid phase thin film, is effective against the water-miscible fuel destruction to foam, makes fire foam quickly to sprawl, thus reaches fast
The purpose of speed fire extinguishing.
