Preferably, the locating rod and the quantity of location hole are one or more.
Preferably, the quantity of the boss is one or more.
Preferably, the propellant cylinder and propellant powder column are cylindrical structural or elliptical cylinder-shape structure.
In addition, the present invention also provides a kind of full method for coating of aerogel generating agent powder column, it comprises the following steps：
Step 1）：The propellant powder column of forming is put into the propellant cylinder with radial positioning mechanism and axial positioning mechanism；
Step 2）：Quantitative liquid-state silicon gel is injected into propellant cylinder, makes propellant cylinder and propellant after silica gel stands and cures
Powder column, which is fixed, becomes an entirety, and stable silica gel is formed between propellant powder column outer surface and propellant tube inner surface and is isolated
Layer, silica gel separation layer coat whole propellant powder column.
Preferably, in step 1）In, by the positioning of the location hole alignment propellant cylinder bottom surface of the propellant powder column of forming
Bar, is inserted into, until propellant powder column bottom surface stops when touching the boss of propellant cylinder bottom surface, realizes position fixing process.
The present invention has the advantage that as follows compared with prior art：
Being fixed the invention enables powder column and propellant cylinder becomes an entirety, and the relative position between powder column and propellant cylinder will not
Change, and form stable silica gel separation layer therebetween, it is final enable propellant powder column stablize burning, it is heat-insulated,
Shockproof and anti-salt is rotten, and improves propellant powder column IP degree of protection；Solves existing aerosol fire-extinguishing device propellant powder column
Defective workmanship in process of production, effectively increases the stability of aerogel generating agent powder column burning and integrally-built stabilization
Property.
