Problems solved by technology

[0004] The existing dry powder containing ammonium phosphate with a mass fraction of 80%-85% uses the traditional ABC process to mix raw materials and auxiliary materials together for silicification. The dry powder produced is not very effective in extinguishing fire, and the shelf life is not very long, and the particle size is relatively coarse. or finer, does not make a good match between dry powder and fire extinguisher

Embodiment 1

[0025] Such as figure 1 Shown, a kind of ABC dry powder fire extinguishing agent production process, described dry powder fire extinguishing agent comprises the ammonium phosphate that mass percentage composition is 80%, described technology comprises the steps:

[0026] (1) Weigh the raw ammonium phosphate;

[0027] (2) Add the above-mentioned ammonium phosphate to the pulverizer for pulverization;

[0028] (3) Separating the above-mentioned pulverized raw materials through a separation device;

[0029] (4) Pass the separated ammonium phosphate into the silicification equipment, add 1% of the mass percentage of silicone oil and auxiliary materials mica, white carbon black and talcum powder, the mass percentage of the said auxiliary materials mica is 5%, the mass percentage of white carbon black The percentage is 3% and the mass percentage of talcum powder is 11% to perform siliconization treatment respectively, and then put into the siliconization equipment after performing...

Embodiment 2

[0036] Such as figure 2 As shown, the rest are the same as in Example 1, the difference is that in the above separation process, the dry powder with a qualified particle size enters the next process flow, otherwise it is re-entered into the pulverizer for pulverization.

[0037] Similarly, the dry powder whose particle size meets the requirements after sieving enters the next process flow, otherwise it will be re-entered into the pulverizer for pulverization.

[0038] The technical solution of this embodiment can not only make the production process of the ABC dry powder fire extinguishing agent achieve the purpose of having a better fire extinguishing effect, but also make the dry powder have better water repellency, no obvious water absorption, and not easy to agglomerate, so that the shelf life is longer. The matching degree is good, and the purpose of fully utilizing the raw materials can also be achieved, saving costs.

Embodiment 3

[0040] All the other are identical with above-mentioned embodiment, difference is that described dry powder fire extinguishing agent comprises the ammonium phosphate that mass percent composition is 84.4%, the silicone oil of 0.1%, the mica of 3%, the white carbon black of 0.5% and the talcum of 12% pink.

Abstract

The invention discloses an ABC dry powder extinguishant production technology. Auxiliary materials comprising mica powder, white carbon black and talcum powder are added to an ABC dry powder extinguishant on the basis of traditional ABC dry powder extinguishants, are individually silicified, and are silicified together with a raw material ammonium phosphate through adding to a mixed silicification device after the individual silicification of the auxiliary materials, so silicon oil contacts with the raw material ammonium phosphate and coats the external surface of the ammonium phosphate as much as possible to reach a full silicification purpose, thereby the silicification effect is good, the shelf life is long, and the granularity can well match with a fire extinguisher.

Description

technical field [0001] The invention relates to a production process of a dry powder fire extinguishing agent, in particular to a production process of an ABC dry powder fire extinguishing agent. Background technique [0002] Halon fire extinguishing agent has the characteristics of low cost and high efficiency, but the main component of halon fire extinguishing agent is halon, which will cause serious damage to the atmospheric ozone layer after use, so it has been discontinued. Since then, there has been no ideal substitute for fire protection Extinguishing. [0003] At present, the most widely used product with better effect is fire-fighting dry powder. Its main raw material is ammonium phosphate, which is easy to absorb water and agglomerate, which is not conducive to the use and storage of dry powder. In order to extend the shelf life of the dry powder and make it easy to store, it is usually achieved through a siliconization process, that is, a layer of silicone oil is...
