preparation example Construction

[0034] The present invention also provides the preparation method of the humic acid crust dust suppressant used for bare ground greening, and the preparation method comprises:

[0035] A. Add 4-8 parts by weight of humic acid, 2-6 parts by weight of pecan gum or sodium carboxymethyl cellulose CMC into 1000 parts by weight of water and stir to dissolve. Preferably, the water-soluble components are first added to water and mixed thoroughly to make an aqueous solution, and then the insoluble components are added for dissolution, for example, sodium carboxymethylcellulose CMC can be dissolved in water first.

[0036] B. After dissolving, add preservatives accounting for 4-8‰ of the total weight of humic acid and Tianqing gum and moss seeds accounting for 0.5-2% of the total weight of humic acid encrustation dust suppressant, and then continue to stir to form an emulsion. Preferably, the duration of continuous stirring is 30-60 minutes, so as to ensure that the emulsion can be form...

Embodiment 1

[0043] Weigh 7 grams of humic acid and 3 grams of Tianqing gum. After mixing the two powders evenly, slowly add 1000 ml of stirring water. After the powder is completely dissolved, add 0.06 ml of preservative and 10 grams of moss seeds, and stir again The solution was homogenized into an emulsion for 40 minutes.

[0044] Spray the prepared crust dust suppressant emulsion evenly on the bare soil surface (the spraying rate is 2 kg / square meter). After the crust dust suppressant is sprayed, a 2-3 cm thick crust layer and a green moss surface layer can be formed on the soil surface, which can effectively prevent the generation of soil dust.

Embodiment 2

[0046] Weigh 4 grams of humic acid and 6 grams of Tianqing gum. After mixing the two powders evenly, slowly add 1000 ml of stirring water. After the powder is completely dissolved, add 0.06 ml of preservative and 10 grams of moss seeds, and stir again The solution was homogenized into an emulsion for 40 minutes.

[0047] Spray the prepared crust dust suppressant emulsion evenly on the bare soil surface (the spraying rate is 2 kg / square meter). After spraying, the crust dust suppressant can form a crust layer about 3 cm thick and a green moss surface layer on the soil surface, which can effectively prevent the generation of soil dust.

Abstract

The invention relates to a humic acid incrusting dust suppressant for barren greening and a preparation method thereof. The humic acid incrusting dust suppressant for barren greening comprises the following components in parts by weight: 4-8 parts of humic acid, 2-6 parts of galactomannan gum or sodium carboxymethyl cellulose (CMC) and 1000 parts of water. The humic acid incrusting dust suppressant also comprises a preservative which accounts for 0.4-0.8% of the total weight except water, and moss seeds which account for 0.5-2% of the total weight of the humic acid incrusting dust suppressant. The humic acid incrusting dust suppressant can be used in various barrens in need of greening and dust suppression, can obviously reduce the flying dust pollution on various bare surfaces after being sprayed, and utilizes bryophytes to green the barren. The bryophytes and humic acid supplement each other; the humic acid provides necessary organic nutrients for the bryophytes; and the bryophytes can effectively increase the water retention property of soil on the premise of greening the bare surface, thereby performing the function of reducing the flying dust pollution on the ground surface.

Description

technical field [0001] The invention relates to a dust suppressant and a preparation method thereof, in particular to a humic acid crust dust suppressant used for greening bare ground and a preparation method thereof. Background technique [0002] Dust pollution has become the largest source of pollution in the world's public nuisance pollution. In recent years, the vigorous development of the mining industry, the increase of the coal transportation industry, the construction of urban infrastructure, and the accumulation of garbage and waste have all made dust pollution more and more serious, especially for dust pollution. PM10 and PM2.5, which have a large contribution rate, have attracted much attention. [0003] With the advancement of science and technology and the continuous improvement of people's living standards, how to reduce dust pollution has attracted people's great attention. At present, the commonly used dust suppression methods include dust suppressants, wet d...
