Abstract
The invention provides a foam fire extinguishing agent capable of foaming. The foam fire extinguishing agent is composed of the following raw materials in parts by weight: 100-150 parts of water, 1-20 parts of a foaming agent, 5-10 parts of diethylene glycol dimethyl ether, 1-5 parts of amomum kravanh gel, 50-100 parts of a retarder, 1-5 parts of a thickening agent, 1-5 parts of xanthan gum, 1-5 parts of a preservative and 100-500 parts of water. According to the foam fire extinguishing agent, air does not need to be sucked. The foaming times are not related with the flow speed and pressure of foam liquid; and meanwhile, formed foam is fine, smooth, uniform and stable.
Description
Technical field
The present invention relates to technical field of fire control, particularly relate to a kind of fire foam that can foam voluntarily.
Background technology
Fire foam kind is a lot, and mainly comprise albumen, fluorine albumen, MJPZ, anti-molten MJPZ and class A foam extinguishing chemical etc., its production technology is different.Albumen, fluoroprotein foam extinguishing agent are in a kettle., with animal protein or vegetable protein for base-material, add alkali partial hydrolysis, concentrated, then add the additives such as stabilizing agent, anticorrisive agent, antifreezing agent, fluorocarbon surfactant and form; Aqueous film-forming foam extinguishing agent is made up of diethylene glycol dimethyl ether, blowing agent, foam stabiliser, anti-burning agent, antifreeze, cosolvent, anticorrisive agent etc., fully stirs in mixing kettle; Anti-molten MJPZ adds water soluble polymer on the basis of MJPZ extinguishing chemical; Class A foam extinguishing chemical, except blowing agent, stabilizing agent, anti-burning agent, antifreeze, also add bleeding agent.
After regular-type foam extinguishing chemical dissolves in carbon dioxide, foaming properties is destroyed, and coefficient of foaming reduces, and drainage time reduces, and 25% drainage time is generally no more than 1min, particularly the synthesis such as aqueous film-forming foam extinguishing agent class A foam A extinguishing chemical.In current China market, extinguishing chemical adopts air suction type foam-making apparatus, and the inspiratory effects of this air suction type device is by the impact of the many factors such as flow velocity, loine pressure, and inspiratory capacity thus the instability become, the air foam of formation is also unstable.In traditional froth fire extinguishing system, foam flow is by the restriction of device parameter; Further, form foam need 5 ~ 10min from starting to, delay best fire extinguishing opportunity.
Summary of the invention
The extinguishing chemical provided of the present invention does not need to suck air.Coefficient of foaming and foam solution flow velocity, the pressure of foam have nothing to do, and the foam simultaneously formed is fine and smooth, even, stable.
For solving the problems of the technologies described above, the invention provides a kind of fire foam foamed voluntarily, it is made up of the raw material of following weight portion, water 100-500 part, blowing agent 1-20 part, diethylene glycol dimethyl ether 5-10 part, cardamom glue 1-5 part, set retarder 50-100 part, polyacrylamide 1-5 part, anticorrisive agent 1-5 part, water 100-500 part.
Preferably, a kind of fire foam foamed voluntarily, it is made up of the raw material of following weight portion, water 200-300 part, blowing agent 5-10 part, diethylene glycol dimethyl ether 7-8 part, cardamom glue 3-5 part, set retarder 30-80 part, polyacrylamide 3-5 part, anticorrisive agent 3-5 part.
Preferably, a kind of fire foam foamed voluntarily, it is made up of the raw material of following weight portion, 200 parts, water, blowing agent 8 parts, diethylene glycol dimethyl ether 8 parts, 4 parts, cardamom glue, set retarder 55 parts, polyacrylamide 4 parts, anticorrisive agent 4 parts.
Preferably, described accelerator is sulfate and phosphatic mixture.
The preparation method of fire foam of the present invention is as follows:
(1) to add water in reactor and solid material, stirring and dissolving.
(2) add water soluble polymer, stir, dissolve.
(3) add set retarder, stir.
(4) reactor is airtight, at 5-10 DEG C, stir lower filling CO 2 1-2h to 1-2MPA.
(5) leave standstill, froth breaking, improves 0.01-0.05MPA by reactor.Extinguishing chemical is made to enter into storage tank.
Beneficial effect of the present invention: extinguishing chemical of the present invention does not need to suck air foaming, but dissolves in extinguishing chemical by carbon dioxide, and when pressure reduces, carbon dioxide discharges from extinguishing chemical, improves fire and disposes speed.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.
A kind of fire foam, is made up of the raw material of following weight portion, 200 parts, water, blowing agent 8 parts, diethylene glycol dimethyl ether 8 parts, 4 parts, cardamom glue, set retarder 55 parts, polyacrylamide 4 parts, anticorrisive agent 4 parts.
Set retarder is sulfate and phosphate mixt.
Preparation method is as follows:
(1) to add water in reactor and solid material, stirring and dissolving.
(2) add water soluble polymer, stir, dissolve.
(3) add pour-point depressant, stir.
(4) reactor is airtight, at 5-10 DEG C, stir lower filling CO 2 1-2h to 1-2MPA.
(5) leave standstill, froth breaking, improves 0.01-0.05MPA by reactor.Extinguishing chemical is made to enter into storage tank.
