1 stability test of test example
Example 1-10, the ore aqueous suspension of reference examples 1-7 and commercially available gel extinguishant, sampling amount are
200g is placed in the beaker of the identical 500mL volume of specification, and 50g liquid carbon dioxide is added in each beaker respectively and goes out
Fiery agent, stands after mixing evenly, observation each group ore aqueous suspension discharged at 1,12,24,36 month water, 36
Month when floccule, 36 months when precipitating and solidification situation at 36 months, floccule is divided into more, general, less, seldom
And nothing, wherein the more quantity for referring to floccule be more than 50, the generally referred to as quantity of floccule between 30-50, compared with
The quantity of floccule is referred to less between 10-30, seldom refers to the quantity of floccule less than 10, nothing refers to not appointing
What floccule generates, and the judgment criteria of precipitating is the height of lower layer after measurement layering, and solidification situation is divided into a large amount of, general, a small amount of
And nothing, largely refer to coagulated volume be more than total volume 50%, generally referred to as coagulated volume be total volume 20%-
50%, it refers to that coagulated volume is less than the 20% of total volume on a small quantity, without no any solidification situation is referred to, the results are shown in Table 1.
The aqueous stability of suspension test result of 1. each group ore of table
As can be seen from Table 1, suspension energy of the ore aqueous suspension of embodiment 1-10 to liquid carbon dioxide fire-fighting agent
Power is stronger, and floccule, precipitating and solidification phenomenon will not be generated in 24 months, also that any moisture is not precipitated, it was demonstrated that the present invention mentions
The stability of the ore aqueous suspension of confession is higher, suspension extinguishing chemical that can be more uniform, improves and ejects in fire extinguishing procedure
The homogeneity of extinguishing chemical, embodiment 8-10 are higher than embodiment 1-7 to the suspension effect of extinguishing chemical significantly, illustrate offer of the present invention
Method can effectively improve the stability of ore aqueous gel；The ore aqueous suspension of reference examples 1-7 is to liquid dioxy
The suspending power for changing carbon extinguishing chemical is poor, the different degrees of precipitation moisture in 24 months, it is more or less produce floccule,
Precipitating and solidification phenomenon, although commercially available gel extinguishant is precipitated moisture, the floccule of generation and solidification phenomenon and substantially conforms to require,
But its precipitating generated is more, it was demonstrated that although commercially available gel extinguishant stability is preferable, its suspension to fire-fighting quipment
It is poor.
The measurement test of 2 attack time of test example
