Example Embodiment

[0024] Example 1,

[0025] Such as figure 1 As shown, an ABC dry powder fire extinguishing agent production process, the dry powder fire extinguishing agent includes ammonium phosphate with a mass percentage of 80%, and the process includes the following steps:

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

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

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

[0029] (4) Pass the separated ammonium phosphate into the siliconization equipment, add 1% by mass of silicone oil and auxiliary materials of mica, white carbon black and talc, and the said auxiliary materials of mica have a mass percentage of 5% and the mass of white carbon black. The percentage of 3% and the mass percentage of talc of 11% are respectively subjected to silicification treatment, and then put into the silicification equipment after individual silicification.

[0030] In the process ...

Example Embodiment

[0035] Example 2,

[0036] Such as figure 2 As shown, the rest is the same as Example 1, the difference is that in the above separation process, the dry powder whose particle size meets the requirements enters the next process flow, otherwise it is added to the pulverizer for pulverization.

[0037] Similarly, after sieving, the dry powder whose particle size meets the requirements enters the next process flow, otherwise it is added to the grinder again for pulverization.

[0038] The technical solution of this embodiment not only enables the ABC dry powder fire extinguishing agent production process to achieve the purpose of having a better fire extinguishing effect, but also makes the dry powder have better water repellency, no obvious water absorption, and not easy to agglomerate, resulting in a longer shelf life. The matching degree is better, and the raw materials can be fully utilized, and the cost can be saved.

Example Embodiment

[0039] Example 3,

[0040] The rest is the same as the above embodiment, the difference is that the dry powder fire extinguishing agent includes 84.4% by mass of ammonium phosphate, 0.1% of silicone oil, 3% of mica, 0.5% of white carbon black and 12% of talc powder.

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...
