Problems solved by technology

[0005] The disadvantages of the above-mentioned patents are: although the foam multiple of the fire extinguishing agent can reach 20 to 200 times, and the foam stability time is ≥ 2.5 hours, it can only make the "inert gas carbon dioxide foam spread in the fire zone and fill its space in a short time." , so that the oxygen concentration in the fire area drops rapidly, causing the fire area to suffocate due to lack of oxygen", it cannot really isolate the contact between the burning coal seam and the air, prevent the coal mine from continuing to burn, avoid the re-ignition of the coal seam, and achieve flame retardancy and fire prevention. Purpose
Ammonium bicarbonate is used as the main raw material of the fire extinguishing agent. During the fire extinguishing process, a large amount of ammonia gas will be released, which pollutes the air in the mine and is not conducive to the health of operators.
[0006] Illite can be transformed into montmorillonite under certain conditions. During the conversion process, illite-smectite mixed-layer minerals, a transition mineral, are first formed. The existence of illite-smectite mixed-layer minerals will affect the mineral properties and process performance of illite, limiting its industrial Application range
[0007] There is a large amount of mixed-layer clay in my country, especially in Shangsi County, Guangxi Zhuang Autonomous Region. Under the sugarcane field that can't be seen at a glance, there is mixed-layer clay with a depth of more than 100 meters, but these mixed-layer clay is very small. Less used in actual production products

Embodiment Construction

[0053] Below in conjunction with embodiment the present invention will be further described:

[0054] 1. The ingredients of the mixed-layer clay reticulated gel foam slurry anti-fire extinguishing agent are composed of the following components by weight percentage: 30% of mixed-layer clay composite flame-retardant foaming agent, 22% of inorganic fiber spray cotton mixture and 48% of water %.

[0055] The production method of the anti-fire extinguishing agent of the mixed-layer clay reticulated gel foam mud of Yimeng: input the ingredients of the fire-resistant agent of the clay reticulated gel foam mud of the mixed layer of Yimeng into the rake type mixer, and stir at a high speed to form the clay net of the mixed layer of Yimeng Gel foam mud fire extinguishing agent, the speed of the rake mixer is controlled at 2400-2800 rpm, and the stirring time is controlled at 12 minutes.

[0056] 2. The ingredients of the compound flame-retardant foaming agent of the mixed-layer clay of...

Abstract

The invention discloses an anti-fire extinguishing agent for clay reticulated gel foam mud with mixed layer of illuminator. The key points of the technical scheme are that it is composed of composite flame retardant foaming agent of mixed layer clay of illuminator, attapulgite clay powder with the function of purifying air, Inorganic fiber spraying cotton, mixed layer clay powder, coal gangue powder, expanded perlite powder, sodium alginate and water. Input the batching of the clay reticulated gel foam mud fire extinguishing agent of the IM mixed layer into the rake type mixer, and stir at high speed to obtain the IMO mixed layer clay reticulated gel foam mud fire extinguishing agent. The reticular gel foam slurry is sprayed onto the burning coal seam by an inorganic fiber sprayer, which is conducive to the formation of an integral reticular gel foam slurry film in the process of fire prevention and extinguishing, which always covers and adheres to the surface of the mine seam, and quickly isolates the combustion The contact between the coal seam and the air prevents the coal mine from continuing to burn, avoids the re-ignition of the coal seam, and achieves the purpose of flame retardancy and fire prevention. It is suitable for fire prevention and extinguishment in coal mines, mine operation areas and forests.

Description

technical field [0001] The invention relates to an anti-fire extinguishing agent, in particular to an anti-fire extinguishing agent for clay reticulated gel foam mud with mixed layer of Illuminate. Background technique [0002] Fully mechanized top-coal caving mining has the advantages of high yield, high efficiency, and low consumption, and has been widely used in many coal production bases in my country. However, due to the high mining intensity of this coal mining method, there is a lot of residual coal left in the goaf, the height of the fall is large, and the air leakage is serious. A series of problems such as fire, gas, and dust that are difficult to solve often occur, especially fire. [0003] Foam fire extinguishing agents are divided into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam and alcohol-resistant foam. [0004] Chinese Patent Publication No. CN 102614615A, publication date: August 01, 2012, titled "a composite foam fire extinguish...
