Description
Technical field
The present invention relates to a kind of preparation methods of insulating corrosion aerosol extinguishing agent, belong to fire engineering field.
Background technique
Fire extinguisher is a kind of portable Fire extinguisher.Chemical substance is placed in fire extinguisher, to rescue fire extinguishing calamity.Fire extinguisher is
One of common fireproofing installation is stored in public place or the place of fire may occur, filling in different types of fire extinguisher
Ingredient it is different, be to aim at different fire alarms and set.Must be noted that when use in order to avoid generating minus effect and causing danger.
Aerosol refers to using solid or liquid as dispersed phase, is formed by colloidal sol by decentralized medium of gas.In general,
This object system be it is stable or metastable, the particle diameter of liquid phase or solid-phase component is less than 1 μm.Aerosol extinguishing agent fire extinguishing
Mechanism are as follows: active group such as O, H, the OH etc. in solid or liquid aersol particle and flame generated by burning occur chemistry and
Physical action such as absorbs oxygen, starvation, absorbs the effects of heat, prevents combustion reaction from persistently carrying out, to reach fire extinguishing
Purpose.Ideal hot aerosol fire-suppressant gas be have fire extinguishing effect gas wrapping the specific solid particle for having fire extinguishing effect
It with the blast that chemical reaction generates, is suspended in the air, ground cut-through object is diffused, due to the original of thermodynamics and molecular dynamics
Reason tracks heat at fire source and puts out a fire for ignition point.It generates in this gas during putting out a fire, if solid
The partial size of grain is too big, then gas cannot carry, and particle can settle quickly, not have the effect put out a fire completely；But if
Particle have it is too small, and be easy driven by air-flow, possibly remote from ignition point or fire location, do not have the fire extinguishing of project verification equally yet
Effect.
Aerosol extinguishing agent in the prior art using when still have following problem and need to solve, comprising: (1) aerosol
