Dust can be divided into two categories according to the size of the particles: large diameter known as dust, heavy weight and easy to settle, the diameter of the small known as floating dust, which floats in the air in the form of aerosols for a long time, people can not see. Dust contains a variety of heavy metals, dust can adsorb a variety of toxic substances, some of which are carcinogenic. Adsorption of toxic substances floating dust everywhere, seriously polluting the environment on which we live.
Pure biological sand and dust suppression agent is a combination of new multi-functional polymer. The degree of crosslinking between the polymer molecules will form a network structure, while the presence of various ionic groups between the molecules, can produce a strong affinity with the ions. Its action mechanism is through the capture, adsorption, agglomeration of dust particles, will be locked in the mesh structure, to play the role of wetting, bonding, coagulation, hygroscopicity, dust prevention, anti-erosion and anti-scouring. Pure biological sand fixing and dust suppressant has good film-forming properties, which can effectively fix the dust and form a protective film on the material surface.
It can be widely used in coal and all kinds of metal and non-metal mining areas, mineral slag dumps, coal and mineral powder transportation, mineral earth storage and unloading yards, building demolition, along the road under construction, thermal power plants, cement factories, iron and steel mills, metallurgical factories, dusty workshops, artificial sandy beaches and sandy soil.
Traditional sand netting is easy to pollute the environment twice and is not durable.
Pure biological sand fixing and dust suppressant can prevent dust, stabilize the soil soil control products, non-toxic, harmless, non-flash point, non-carcinogenic, non-stimulating to the eyes, does not cause corrosion of metals. It can be completely dissolved in water when mixed with water before use, stabilized after spraying, and will not be washed away by rain. It does not affect plants, has low toxicity to aquatic animals, and is safe for groundwater. It is a pure biological derivative composite product that forms a good bond with the soil. It is applied to a wide range of soil surfaces after mixing with water. The product contains a unique binder that provides a durable, highly permeable surface that suppresses dust and stabilizes the soil.
The production of environmentally safe sand and dust suppressants has a wide range of applications, including industrial and mining enterprises, construction sites, and transportation infrastructure. It is a completely biodegradable product, the main components are modified starch and soybean extract, which is not harmful to human body and environment, and can decompose by itself after a certain period of time, using this product can solidify the soil, but will not damage the soil. Mix the product with water and spray it on the treated surface. Once it is applied to the soil or aggregate, the copolymer molecules bind, creating a bond between the soil or aggregate particles. The unique advantage of the product is its complex molecular structure of nanoparticles which are cross-linked with each other. This product mainly uses nanotechnology to stabilize the soil and control erosion and dust.
Principle of action: This product is used in the same way as watering a lawn, the product will penetrate deep into the soil and form a solid surface. Depending on the needs of the application, and if used in larger quantities, the surface will remain stable and firm for several years. If this happens, the soil will be as strong as concrete. If it is used in a small amount, the soil can be kept stable and permeable for a short period of time. This product also meets the dust suppression effect. It is an environmentally safe product that does not damage the soil.
Development trend:
(1) In order to make the dust suppressant effect better, its preparation process will become more and more complex, dust suppressant will gradually to the composite and specialized direction. Chemical dust suppressants will be more closely integrated with other forms of dust suppression technology.
(2) With the rapid development of polymer chemical materials, the future of polymer super-absorbent will become cheaper and cheaper, will be more widely used.
(3) With the rapid development of chemical industry, chemical dust suppressants will tend to be simpler and cheaper. Chemical dust suppressants are not only widely used in dust control and dust suppression, but also applied to many new areas. Such as: adding dust suppression agent can change the water logic of the disturbed soil properties; in MgO such as weak alkali add wetting agent, some of its properties and NaOH such as strong alkali similar or even better; ca2 type binder can affect the framework of muscle fibers and so on.
(4) Chemical dust suppressants have begun to transition to organic polymers from the use of heavy oils and inorganic salts, paying more attention to the safety, maneuverability and continued effectiveness of dust suppressant use.
Usage:
The use of solid sand and dust suppressant can generally be taken manually, mechanically or professional spraying station and fixed spraying system method, etc., the pure biological solid sand and dust suppressant diluted liquid evenly sprayed on the surface of the material or dusty area, you can realize the effect of dust prevention and dust reduction. Specific use and dosage can be adjusted according to the site conditions, in order to achieve the desired effect.
First, spraying equipment
Small yards can be sprayed with backpack spraying devices or dosing trucks.
Large stockyards can be installed fixed spraying device, can also be used vehicle-mounted or professional spray trucks for spraying, range up to 18 ~ 200m.
Mobile train, car transportation, the need to build solid sand dust suppressant spraying base station, or the acquisition of mobile spray trucks to operate, conveyor belt can be installed dry mist spraying equipment.
Underground and dust workshop dust reduction, can be installed atomized dust reduction spray device. The device can be high-pressure ultra-fine mist to capture the fine dust in the air, and then play a good atomized dust reduction effect.
It should be noted that improper selection of sand fixing and dust suppressant will corrode the equipment or affect the quality of the sprayed material.
Second, the dilution method
Solid dust suppressant dilution:
1. Newly built standard spraying base station is recommended to be equipped with multi-functional high mixing dispensing system, in order to solve the problem of long-term water-in-powder.
2. Stir while adding water, the stirring time is 3-15 minutes to ensure that the solid sand dust suppressant is dissolved evenly, and a slightly longer stirring time is appropriate.
3. put the sand fixing and dust suppressant into the water container according to the proportion of the equipment, while putting and stirring, after stirring evenly, it can be used.
Liquid sand and dust suppressant dilution:
Directly pour the original liquid dust suppressant into the equipment container (container must be part of the water, to avoid adherence to the bottom of the container), and then one-time addition of the required water, the use of water impact dilution and dissolution can be used.
Third, spraying method
According to different dust suppression places and micro-environment, the methods are different, and the effect is also different. Please consult with professional technicians and ask for technical regulations, and request on-site technical service if necessary.
Fourth, Advantages
1. Protecting the environment, able to remove dust particles above 2.5 microns.
2. non-corrosive, non-polluting, biodegradable, will not cause secondary pollution.
3. Resistant to wind erosion and rainwater erosion.
4. can effectively reduce and minimize material loss.
5. It can effectively reduce the dust hazard and protect the health of workers and neighboring people.
V. Precautions
1. If there is any spillage, please clean it up in time, and use moisturizing dust suppressant for cement road.
2. Please clean and maintain the equipment in time after use, if it gets into the mouth, nose and eyes by mistake, please flush it with water immediately and consult a doctor in time.
3. Choose the right product and brand service.
