Description
Technical field
The present invention relates to the preparation method of a kind of fire extinguisher, a kind of environment-friendly type ultra-fine dry powder rustless steel fire extinguisher
Preparation method.
Background technology
The development of domestic fire extinguisher industry is with rapid changepl. never-ending changes and improvements, the weight that particularly recent years, safety fire fighting was worked by government
Depending on and put into energetically.Make fire extinguisher market more vigorous.But compared with the requirement of international market, domestic fire extinguisher product
Class need to improve.
Along with people's raising to safety fire fighting work attention degree, fire extinguisher market is also brought rapidly up, particularly high-grade
Fire extinguisher product is more favored.China is whole world fire extinguisher big producing country, and a lot of countries fire extinguisher is all purchased in China,
And more and more higher to the manufacture requirements of fire extinguisher, therefore research and develop the technique of exquisiteness, superpower extinguishing property, environmental protection corrosion-free etc.
Advantage, can meet and just determine the fire extinguisher of parameter request and become the unremitting pursuit of numerous fire extinguisher manufacturer.
Summary of the invention
The technical problem to be solved is for the deficiencies in the prior art, it is provided that a kind of new, production technology letter
List is reasonable, the preparation method of the environment-friendly type ultra-fine dry powder rustless steel fire extinguisher of good product quality.
The technical problem to be solved is to be realized by following technical scheme.The present invention is a kind of environmental protection
The preparation method of type ultra-fine dry powder rustless steel fire extinguisher, is characterized in, its step is as follows: use automated production equipment, uses
Corrosion resistant plate makees stack shell material, by corrosion resistant plate roll barrel, weldering stack shell, the upper and lower end socket of punching press, welds, polishes and canned fire extinguishing
Agent step prepares environment-friendly type ultra-fine dry powder rustless steel fire extinguisher.
The preparation method of environment-friendly type ultra-fine dry powder rustless steel fire extinguisher of the present invention, its further preferred technical side
Case is: weld on inner wall of barrel during weldering stack shell.
The preparation method of environment-friendly type ultra-fine dry powder rustless steel fire extinguisher of the present invention, its further preferred technical side
Case is: uses the fire extinguisher device head member with the pressure capability of antidetonance, is provided with automatic injection apparatus, i.e. at device head on device head
On employ fusible alloy, when temperature reaches 100 DEG C, fusible alloy melts automatically, extinguishing medium under the effect of the pressure from
Dynamic spouting from the fusible alloy hole melted.
The preparation method of environment-friendly type ultra-fine dry powder rustless steel fire extinguisher of the present invention, its further preferred technical side
Case is: the particle diameter of described extinguishing chemical is less than 20 microns.
The preparation method of environment-friendly type ultra-fine dry powder rustless steel fire extinguisher of the present invention, its further preferred technical side
Case is: described extinguishing chemical is ammonium dihydrogen phosphate.
The preparation method of environment-friendly type ultra-fine dry powder rustless steel fire extinguisher of the present invention, its further preferred technical side
Case is: hydroscopicity≤0.9% of described extinguishing chemical.
The inventive method, by changing the technical parameter of fire extinguisher, applies the equipment of advanced person, the technique of advanced design, development
Fire-extinguishing agent, thus obtain fire extinguisher attractive in appearance, safe and environment-friendly, that extinguishing property is superior.Extinguishing chemical is moistureproof, agglomeration resistance ability
Higher, the effect duration of extinguishing chemical was up to 5 years.The key technical indexes of obtained fire extinguisher is as follows:
Extinguishing chemical of the present invention uses jet mill to pulverize primary raw material ammonium dihydrogen phosphate, to reach granularity≤20 micron
Purpose, its main fire-fighting principle: 1, the high inhibition effect to flaming combustion.Flaming combustion is a kind of chain reaction.Fuel
Molecule is activated under the high temperature of burning or under its energy formed, and produces free radical or active group in the presence of oxygen
Cause, and by these, there is high-octane free radical propagation reaction, maintain persistently carrying out of burning.Ultra-fine dry powder mixes with flame
Time, fire extinguishing component captures rapidly burning free radical, makes the speed that free radical is consumed more than the speed produced, and burning free radical is very
Exhausting soon, chain reaction course is i.e. terminated, and flame extinguishes rapidly.2, smothering action strong to surface combustion.Ultra-fine dry powder is to flutterring
Flaming combustion of going out has good speed and efficiency, and has the surface combustion (glowing) of general solid matter and well extinguish work
With.When ultra-fine dry powder crystal powder contacts with the comburant surface of calcination, there is series of chemical, at the surface of solids
It is melted and is formed a glassy cover layer under high temperature action to be separated with surrounding air by the surface of solids, make burning suffocate.3、
To thermal-radiating screening every and cooling effect.When using ultra-fine dry powder fire extinguishing, the powder as heavy clouds mixes mutually with flame, decomposes heat absorption
Reaction, the partial heat of absorbable flame, these decomposition reactions produce some active gases is not such as: carbon dioxide, steam
Deng, the oxygen concentration of combustion zone is had diluting effect, makes the combustion reaction of fire weaken.
Additionally, ultra-fine dry powder extinguishing agent is zero to atmospheric ozone layer depletion latent energy value (ODP), chamber effect potential value
(GWP) it is zero, non-stimulated to human body skin and respiratory tract, corrosion-free to protection, nontoxic.After fire extinguishing, residue is the most clear
Reason, can be widely applied to produce and various place of living, in order to A, B, C class fire and the charging equipment fire puted out a fire to save life and property.
In the inventive method, ultra-fine dry powder extinguishing agent preferable particle size is less than 20 microns, does not lumps, is not subject to
Tide, preferably≤0.9%, unit volume fire-fighting efficiency should reach 2-3 times of halon fire agent, common powder extinguishing agent to water content
5-6 times, 10-12 times of carbon dioxide.
The cylinder of the fire extinguisher that the inventive method produces selects the stainless steel material of stable chemical performance, and product disposably closes
Lattice rate is more than 95%, and welding job efficiency is high.Valve is selected fusible alloy device, mainly studies the material of fusible alloy
Material is selected and preparation, will reach predetermined target: can bear operating pressure under normal conditions 2.5 times, and can be at once when 100 DEG C
Fusing.
Compared with prior art, the environment-friendly type ultra-fine dry powder rustless steel fire extinguishing appliance that the inventive method prepares is for extinguishing concentration
Low, speed is fast, efficiency is high, environmental protection, pollution-free, non-stimulated, corrosion-free and good mobility, dispersivity and electricity edge, be difficult to
The advantages such as the effects such as caking are notable, safe and reliable, effect duration length.
