preparation example Construction

[0028] The preparation method of dust inhibitor includes the following steps:

[0029] Add appropriate amount of water to the reaction kettle, add 10%-15% surfactant and 10%-15% stabilizer, slowly add 5%-10% wetting agent and stir after the surfactant and stabilizer are fully dissolved Dissolve, and finally add 5%-10% antifreeze additives, add water to the specified concentration.

[0030] among them:

[0031] The surfactant is one or a mixture of sodium lauryl sulfate, sodium lauryl sulfonate and sodium lauryl sulfate.

[0032] The stabilizer is selected from one or a mixture of polyacrylate, polyvinyl alcohol, hydroxymethyl cellulose, and hydroxyethyl cellulose.

[0033] The wetting agent is selected from sucrose and water-soluble starch or a mixture of two.

[0034] The antifreeze auxiliary is selected from one or a mixture of calcium chloride, sodium chloride and potassium chloride.

Embodiment 1

[0037] Calculated by weight percentage, the total amount of each raw material is 100%; add an appropriate amount of water to the reactor, add 15% sodium lauryl sulfate and 15% polyacrylate, and wait until sodium lauryl sulfate and polyacrylate After the acrylate is fully dissolved, slowly add 10% sucrose and stir to dissolve, finally add anti-sodium chloride 5%, and finally add the remaining water to make the product reach the specified concentration to obtain the product road dust inhibitor.

[0038] When used on site, it is diluted 1:200 with water, and then sprayed to prevent dust in the mine. The dust concentration in the air before spraying the dust remover is 180mg.m 3 . The dust concentration in the air after spraying the dust remover is 24.5mg.m 3 . The dust removal efficiency is 86.4%. The dust removal effect is obvious.

Embodiment 2

[0040] Calculated by weight percentage, the total amount of each raw material is 100%; add an appropriate amount of water to the reactor, add 15% sodium dodecyl sulfonate and 10% polyvinyl alcohol, and wait for the dodecyl sulfonic acid After sodium and polyvinyl alcohol are fully dissolved, slowly add water-soluble starch 5% and stir to dissolve, finally add anti-calcium chloride 5%, and finally add the remaining water to make the product reach the specified concentration to obtain the product road dust inhibitor.

[0041] When used on site, it is diluted 1:100 with water, and then sprayed on the mine site to prevent dust.

Abstract

The present invention discloses a mine field dust emission inhibitor and a preparation method thereof. The raw materials of the mine field dust emission inhibitor comprise a surfactant, a stabilizer, a wetting agent, an anti-freezing auxiliary agent, and water. During preparation, a proper amount of water is firstly added into a reaction kettle, and the surfactant and the stabilizer are added into the reaction kettle; after the surfacant and the stabilizer are sufficiently dissolved, the wetting agent is slowly added, and dissolved by stirring; then, the anti-freezing auxiliary agent is added; and finally, the residual water is added until determined concentration. According to the mine field dust emission inhibitor disclosed by the invention, the dust suppression principle of the mine field dust inhibitor is that the surfactant is utilized to form an isolating membrane on the contact surface of dust and air, and the isolating membrane has good water carrying property and adhesive property, so that the isolating membrane on the dust surface has stronger wettability and stability, and small-particle dust is aggregated into a large-particle solid, thereby achieving an ideal dust falling effect. and by adding a small amount of salt, the dust inhibitor has certain anti-freezing effect.

Description

Technical field [0001] The invention belongs to the field of environmental protection, and relates to a dust suppressant, in particular to a dust suppressant used in mine dust and a preparation method thereof. Background technique [0002] As we all know, dust pollution is one of the world's public hazards. Many human activities will produce dust pollution, especially the mining industry. my country is a big mining country, with various mines spread all over the country, with regional characteristics. The current mining methods are mainly blasting, mechanical chiseling, cutting, friction, etc. These mining operations will generate a large amount of dust, which brings great harm and environmental pollution to the workers in the mining area. If this kind of pollution is not treated in time, it will lead to regional dust pollution and form local signs. [0003] According to the cause of dust generation, it is divided into two categories: natural floating dust and productive dust. N...
