The present invention selects mass fraction >=35% of industrial hydrogen peroxide, takes production scene to add water and adjusts the batching percentage of industrial hydrogen peroxide, is conducive to reduce freight and production cost, improves the foaming quality of product.
First inorfil is sprayed in the batching input plough type batch mixer of cotton mixture, stirring at low speed is that inorfil sprays cotton mixture, be conducive to by cotton inorfil spraying with flyash, colliery powder, swelling perlite powder and the uniform shredding of sodium alginate, fragmentation, be uniformly mixed and be integrated.
Although flame-retardant expanded dose of coal ash compound type adds water after high-speed stirred at flame-retarding fire-extinguishing scene, can discharge fast a large amount of gas, form cavernous foam mud, can be for flame-retarding fire-extinguishing, but use merely flame-retardant expanded dose of coal ash compound type, can only be applicable to general fire-retardant and anti-fire extinguishing on ground, and there is its particularity for the material of anti-fire extinguishing in colliery, require fire-prevention extinguishing agent to there is good mobility, permeability, thixotropy and adhesion property, not only can in colliery, put out a fire, also to there is rapidly contacting of isolated burning coal layer and air, stop colliery to burn away, avoid the function of coal seam resume combustion.
The present invention has formed a kind of Novel coal ash network gel foam mud fire-prevention extinguishing agent after spraying cotton design of mixture by flame-retardant expanded dose of coal ash compound type and inorfil, can form fast a kind of network gel foam mud of sticky porous.
Network gel foam mud is ejected into the coal seam of burning by inorfil flush coater, be conducive to generate a kind of network gel foam mud film of globality in anti-fire extinguishing procedure, this network gel foam mud film is a kind of flexible film, can change along with the displacement of ore bed the shape of film, filling is between float coal and the rock crevice of inbreak, the obstruction passage that leaks out, minimizing is leaked out.
Network gel foam mud film covers the surface that sticks to ore bed all the time, rapidly isolated burning coal layer contacts with air, stop colliery to burn away, avoid coal seam resume combustion, reach the object of fire-retardant and anti-fire extinguishing, and can reduce the pollution of pernicious gas, the surface that network gel foam mud film covers ore bed can not produce a large amount of water vapours, the danger that does not exist water-gas blast and water vapour to hurt sb.'s feelings.
In the process of anti-fire extinguishing, network gel foam mud film at high temperature slow dehydration produces steam, absorbs large calorimetric, thereby can effectively reduce the temperature of inside, coal seam, and network gel foam mud film can keep certain wettability for a long time, prevents coal seam resume combustion; When after the slow dehydration of network gel foam mud film, spray water was sprayed on network gel foam mud film surface in the past, in network gel foam mud film, high hydroscopic resin and cellulose water suction continue to expand, the anti-fire extinguishing effect of recovering and strengthen network gel foam mud film, the effect of anti-fire extinguishing will exceed more than 24 hours.
The raw materials such as diatomite after the Concave-convex clay rod after the rice hulls of the concave convex rod potter's clay powder with air purification function after by the sticky Concave-convex clay rod of height, quick dissolved sodium silicate, zeolite powder, acidifying, zeolite, the acidifying after acidifying, bentonite, the acidifying after acidifying, volcanic rock, alumine, cacumen biotae, aluminium silicate fiber peacekeeping polyacrylamide form; There is good caking property, plasticity, thixotropy, fire resistance and heat endurance, effectively harmful substance in absorbed air, protection of the environment and enhancement people's is healthy.
The gas that flyash network gel foam mud fire-prevention extinguishing agent produces in foaming process is lighter than gel foam mud; have a certain amount of gas ionization on gel foam mud film upper strata; can not have a negative impact to the coal seam resume combustion below gel foam mud film, and the oxygen containing in gas can contribute to protect, miner or fire fighter's is healthy.
Flyash network gel foam mud fire-prevention extinguishing agent is a kind of fire-retardant fireproofing extinguishing materials of high-quality, carrying out in the process of anti-fire extinguishing, do not produce carburization zone and flue gas, inorfil spraying cotton fiber in network gel foam mud film and other batching interweave and are bonded as one, formation has the dimensional network structure of some strength and toughness, remain the integrality of network gel foam mud film, improve the efficiency of anti-fire extinguishing.
Utilize flyash network gel foam mud fire-prevention extinguishing agent to carry out anti-fire extinguishing, technique is simple, equipment needed thereby is few, nontoxic, free from environmental pollution, there is good mobility, permeability, thixotropy and adhesion property, be conducive at freely burning fire and leak out the on-the-spot application of mine serious, not only effectively fire-retardant and anti-fire extinguishing, also have adsorption cleaning air, reduce the function of mine environment pollution, meet the requirement of coal mine underground coal bed control spontaneous combustion and fire, put out a fire fast and effectively in time and prevent coal seam resume combustion, guaranteeing mine safety.
Flyash network gel foam mud fire-prevention extinguishing agent, taking flyash as primary raw material, is not only conducive to improve resource utilization, turns waste into wealth, and can also reduce land occupation, and protection and environment purification are saved the energy, reduce production costs, and increase economic efficiency.
Flyash network gel foam mud fire-prevention extinguishing agent is applicable to the anti-fire extinguishing of colliery, other mine operation district and forest.
