Problems solved by technology

The particle size of commonly used dry powder fire extinguishing agents is between 10 and 75 μm, which has poor dispersibility and relatively small specific surface area
Therefore, the total specific surface area of ​​the quantitative dry powder is small, the mass of a single particle is large, the sedimentation speed is fast, and the decomposition speed is slow when heated, resulting in a small ability to capture free radicals, so the fire extinguishing ability is limited, to a certain extent. Application range of dry powder fire extinguishing agent

Embodiment Construction

[0017] 1. Raw material treatment, using natural zeolite as raw material, adding it to the calcining kiln, heating to 800°C for 1 hour, and then crushing to make coarse powder;

[0018] 2. Activation modification treatment:

[0019] 2. 1. Pickling: add 50 kg of sulfuric acid aqueous solution with a volume ratio of 50% to 100 kg of zeolite coarse powder, and react for 2 hours, so that metal ions other than silicon aluminum in the zeolite can be acidified and synthesized into salts, and pickled , to remove metal ions and related salts;

[0020] 2.2. Alkali washing and pore expansion: Dissolve 50% sodium hydroxide into 50% water to form an alkali washing solution, add 50 kg of alkali washing solution to 100 zeolite coarse powder and react for 2 hours, neutralize the untreated The precipitated acids and salts dissolve part of the non-metallic mineral components at the same time, making the zeolite form a skeleton composed of silica and alumina. This process is pore expansion. Afte...

Abstract

The invention provides a preparation method of a fire extinguishing and disinfecting agent. The preparation method comprises the processes of raw material treatment, activated modification treatment,acid cleaning, alkali cleaning and reaming, water washing, photocatalyst loading and mixed powder grinding and refining treatment so as to prepare a finished product of the fire extinguishing and disinfecting agent. The prepared fire extinguishing and disinfecting agent can extinguish a fire source, simultaneously eliminate burning flue gas as well as adsorb and disinfect the volatile components of the flue gas, so that after the fire source is extinguished, no toxic gas pollution exists in a room, and the personnel in the fire source room can be protected. The fire extinguishing and disinfecting agent provided by the invention is suitable for being used as a fire extinguishing and disinfecting agent.

Description

technical field [0001] The invention proposes a fire extinguishing agent in the field of fire protection, specifically a preparation method of a fire extinguishing disinfectant. Background technique [0002] At present, the dry powder fire extinguishers used in our country are equipped with dry powder fire extinguishing agents such as ammonium phosphate salts. This dry powder fire extinguishing agent is easy to flow and dry. It is composed of inorganic salts and crushed and dried additives, which can effectively extinguish the initial fire. The fire extinguishing component is the core of the dry powder fire extinguishing agent. The substances that can play a role in fire extinguishing mainly include: K2CO3, KHCO3, NaCl, KCl, (NH4) 2SO4, NH4HSO4, NaHCO3, K4Fe (CN) H2O, Na2CO3, etc., which have been produced in China at present The products are: ammonium phosphate, sodium bicarbonate, sodium chloride, potassium chloride dry powder fire extinguishing agent. Each kind of fire e...
