Description

Dust suppressant and application method thereof

[0001] The present invention relates to a dust suppressant and a method for applying the same, which can suppress the generation of dust, has excellent biodegradability, can prevent soil loss from a treated area when applied to soil, can suppress collapse when applied to a slope, can store moisture when it rains, and can improve soil fertility.

[0002] During the development of reclaimed land, the quality of life of nearby residents is deteriorating due to the dust generated from the reclaimed land, and huge economic and environmental losses are being incurred, such as deterioration of air quality and soil loss due to wind erosion. For example, in the case of the Saemangeum reclaimed land, since the seawall was completed in 2006, the surface has dried and sodium ions (Na) have been released. + ) caused soil particle dispersion and poor soil aggregation, resulting in the disappearance and filling of constructed rice paddy embankments and waterways, and civil complaints and damage due to the generation of dust have emerged as major environmental problems. In response, the Korea Rural Community Corporation planted halophytes, such as Tongtungmadi, in an area of ​​approximately 2,421 ha in order to suppress dust generation and minimize environmental problems in the reclaimed land exposed after the Saemangeum seawall construction. Although planting such halophytes can be a very useful and practical method in terms of soil conservation, the effectiveness was very limited because it required a lot of labor and cost to collect and sow halophyte seeds and maintain the germination of halophytes. In addition, in early spring and winter when dust mainly occurs, halophytes wither, making it difficult to maintain vegetation.

[0003] Other methods used to control dust in agricultural land include mulching and the use of soil conditioners. However, mulching is not widely used because it is impractical to apply it to vast reclaimed agricultural lands. Soil conditioners are mainly synthesized from high molecular polymers such as polyvinyl acetate (PVAC), polyvinyl alcohol (PVA), polyacrylic acid (PAA), and polyacrylamide (PAM). Among these, polyacrylamide (PAM) is the most widely used. However, its use has been rapidly declining recently as acrylamide monomer, a breakdown product of PAM, has been recognized as neurotoxic and a potential carcinogen.

[0004] To minimize the generation of dust in reclaimed land, methods for soil aggregation have been studied. Soil aggregation occurs when various soil clay minerals combine physically and chemically to increase soil particle size. It is generally known that stable aggregation is formed when the content of inorganic substances such as calcium and iron increases. Furthermore, organic matter and numerous microbial secretions, such as natural polymers like polysaccharides, hemicellulose, and uronides, are known to contribute to aggregation through cationic cross-linking. Common organic resources applied to agricultural land include rice straw, compost, and dead plant and animal remains. These organic materials undergo microorganism-induced decomposition to form natural polymers, which are then synthesized by microorganisms and persist in the soil. However, the recent increase in the use of agricultural byproducts such as rice straw and rice husks for other purposes has led to a shortage of agricultural byproducts. Therefore, securing new organic resources and applying them to agricultural land is urgently needed.

[0005] Meanwhile, in the case of conventional dust suppressants, although they could suppress the generation of dust, they had problems such as poor biodegradability due to the use of conventional synthetic polymer chemicals with high toxicity and persistence in the environmental ecosystem, or even if biodegradability was good, they could not prevent soil loss in the treated area when applied to soil, could not suppress collapse when applied to slopes, could not store moisture when it rained, and could not improve soil fertility.

[0006] Accordingly, there is an urgent need to develop a dust suppressant that can suppress the generation of dust, has excellent biodegradability, prevents soil loss from the treated area when applied to soil, suppresses collapse when applied to slopes, stores moisture when it rains, and improves soil fertility.

[0007] The present invention has been devised in consideration of the above points, and the purpose of the present invention is to provide a dust suppressant and a method of applying the same, which can suppress the generation of dust, has excellent biodegradability, can prevent soil loss from a treated area when applied to soil, can suppress collapse when applied to a slope, can store moisture when it rains, and can improve soil fertility.

[0008] To solve the above-described problem, the present invention provides a powder-type dust suppressant comprising seaweed powder and pine rosin powder.

[0009] According to one embodiment of the present invention, the seaweed powder may be kelp powder, and the pine rosin powder may be pine rosin powder.

[0010] In addition, the above-mentioned dust suppressant may contain the seaweed powder and pine pine powder in a weight ratio of 1:0.5 to 1.5.

[0011] Additionally, the seaweed powder may have an average particle size of 7 to 25 μm.

[0012] Additionally, the rosin powder may have an average particle size of 45 to 80 μm.

[0013] Additionally, the above dust suppressant may further include herbal extract powder.

[0014] Additionally, the herb extract powder may have an average particle size of 120 to 330 μm.

[0015] In addition, the above-mentioned dust suppressant may further include 1 to 5 parts by weight of the herb extract powder per 100 parts by weight of the seaweed powder.

[0016] Additionally, the above-mentioned dust suppressant may have an average particle diameter of 30 to 60㎛.

[0017] In addition, the present invention provides a method for applying a dust suppressant, which includes a step of treating the above-described dust suppressant and water to a treatment area.

[0018] According to one embodiment of the present invention, the step of treating the treatment portion may be performed by mixing the dust suppressant and water and treating the treatment portion, by treating the dust suppressant to the treatment portion and then treating water to the treatment portion, or by treating the water to the treatment portion and then treating the dust suppressant to the treatment portion.

[0019] The dust suppressant of the present invention and its application method can suppress the generation of dust, have excellent biodegradability, can prevent soil loss from the treated area when applied to soil, can suppress collapse when applied to a slope, can store moisture when it rains, and can improve soil fertility.

[0020] Figure 1 is a photograph evaluating the level of dust generation in soil treated with a dust suppressant according to one embodiment of the present invention and untreated soil.

[0021] Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein.

[0022] The dust suppressant according to the present invention is implemented in a powder form including seaweed powder and pine pine powder.

[0023] First, the above seaweed powder will be explained.

[0024] The above seaweed powder suppresses the generation of dust, has excellent biodegradability, can prevent soil loss from the treated area when applied to soil, can store moisture when it rains, and has the function of improving soil fertility.

[0025] The above seaweed powder may be used without limitation as long as it is a known seaweed powder, but kelp powder is preferable as it can suppress the generation of flying dust, has excellent biodegradability, can prevent soil loss in the treated area when applied to soil, can store moisture when it rains, and can exhibit the function of improving soil fertility.

[0026] Furthermore, if the seaweed powder is kelp, the flavonoids contained in kelp may be even more beneficial in terms of enriching the soil and promoting plant growth. Furthermore, kelp, being a mucilaginous material, may be even more beneficial in terms of its ability to store water when it rains, while also exhibiting the aforementioned effects.

[0027] The above seaweed powder may have an average particle size of 7 to 25 μm, and preferably an average particle size of 10 to 22 μm. If the average particle size of the seaweed powder is less than 7 μm, the moisture storage function may be reduced, and the effect of preventing soil loss in the treated area may be reduced. If the average particle size of the seaweed powder exceeds 25 μm, the effect of suppressing the generation of dust may be reduced.

[0028] The following describes the above rosin powder.

[0029] The above rosin powder suppresses the generation of flying dust, has excellent biodegradability, and exhibits the function of suppressing collapse when applied to a slope.

[0030] The above pine rosin powder may be used without limitation as long as it is a known pine rosin powder, but pine rosin powder is preferable as it is more advantageous in terms of suppressing the generation of flying dust, exhibiting excellent biodegradability, and exhibiting the function of suppressing collapse when applied to a slope.

[0031] In addition, the average particle size of the rosin powder may be 45 to 80 μm, and preferably, the average particle size may be 50 to 75 μm. If the average particle size of the rosin powder is less than 45 μm, the function of suppressing collapse when applied to a slope may be reduced, and if the average particle size of the rosin powder exceeds 80 μm, the effect of suppressing the generation of flying dust may be reduced.

[0032] Meanwhile, the above-mentioned dust suppressant may contain the seaweed powder and pine sap powder in a weight ratio of 1:0.5 to 1.5, preferably 1:0.7 to 1.3. If the weight ratio of the seaweed powder and pine sap powder is less than 1:0.5, the function of suppressing collapse when applied to a slope may be reduced, and if the weight ratio exceeds 1:1.5, the moisture storage function may be reduced, and the effect of preventing soil loss in the treated area may be reduced.

[0033] Meanwhile, according to one embodiment of the present invention, the dust suppressant may further include herbal extract powder.

[0034] The above herbal extract powder can improve the fertility of the soil while also providing an antibacterial effect to the soil.

[0035] In addition, the herb extract powder may have an average particle size of 120 to 330 μm, and preferably an average particle size of 150 to 300 μm. When the average particle size of the herb extract powder satisfies the above range, it may be more advantageous in terms of improving soil fertility while also exhibiting a function of imparting an antibacterial effect to the soil.

[0036] In addition, the above-mentioned dust suppressant may further contain 1 to 5 parts by weight of the herb extract powder, and preferably 1.5 to 4.5 parts by weight, based on 100 parts by weight of the seaweed powder. If the herb extract powder is less than 1 part by weight based on 100 parts by weight of the seaweed powder, the soil fertility may not be improved to the desired level, and the soil antibacterial effect may be reduced. In addition, if the herb extract powder exceeds 5 parts by weight, the moisture storage function may be relatively reduced, the soil loss prevention effect of the treated area may be reduced, and the effect of suppressing the generation of dust may be reduced.

[0037] In addition, the above-mentioned dust suppressant may have an average particle diameter of 30 to 60 μm, and preferably an average particle diameter of 35 to 55 μm.

[0038] If the average particle size of the above dust suppressant is less than 30㎛, the moisture storage function may be reduced, the effect of preventing soil loss in the treated area may be reduced, and the function of suppressing collapse when applied to a slope may be reduced. If the average particle size exceeds 60㎛, the effect of suppressing dust generation may be reduced.

[0039] Meanwhile, as described above, the above-mentioned dust suppressant is implemented in powder form, and thus can be more advantageous in achieving the purpose of the present invention.

[0040] Meanwhile, the present invention provides a method for applying a dust suppressant, which includes a step of treating a treatment part with the dust suppressant described above and water.

[0041] At this time, the step of treating the above-mentioned treatment part may be performed by mixing the above-mentioned dust suppressant and water and treating the above-mentioned treatment part, or by treating the above-mentioned dust suppressant and then treating the above-mentioned water to the above-mentioned treatment part, or by treating the above-mentioned water to the above-mentioned treatment part and then treating the above-mentioned dust suppressant to the above-mentioned treatment part.

[0042] The dust suppressant of the present invention and its application method can suppress the generation of dust, have excellent biodegradability, can prevent soil loss from the treated area when applied to soil, can suppress collapse when applied to a slope, can store moisture when it rains, and can improve soil fertility.
