mineral powder dust suppressant is also called windproof dust-fixing agent, which is a product that replaces dust-proof net and long-term dust control. Because this product can make sand and dust obtain the function of soil, it is also called ecological restoration material. The windproof dust-fixing agent has anti-reverse components and will no longer dissolve in water after drying, so it can resist rainwater brewing. This product has been successfully used to control various pollution sources such as coal storage and transportation in power plants, ports, and mining areas, and mineral material storage and transportation. It has also been applied to the prevention and control of sand and dust pollution in tailings pond control, desertification areas, etc. Ecological restoration and dust prevention on construction sites and roads.
Compared with the commonly used windproof and dustproof nets, windproof and dustproof agents have many advantages as follows:
1. The dust-proof net is mainly made of polyethylene, etc. It will age after four months of use, be torn up and scattered by wind and rain, and become a secondary pollution to the environment; and as a soil conditioner The dust-fixing agent has been tested by a third party to prove that it has no negative impact on the soil and water quality, and it will turn sand and dust into soil properties, such as water retention, fertilizer retention, increase adhesion to plant roots, etc.
2. The mesh structure of the dust-proof net makes its suppression of dust limited; and the solidified dust after the application of the wind-proof dust-fixing agent will be completely controlled and no dust will be formed. 3. The anti-return component in the dust-fixing agent will no longer dissolve in water after curing, so it has the function of resisting rain erosion, and after absorbing rain, it can retain water and moisturize, which is beneficial to plant growth.
4. it has been noticed that the laid dust-proof net is often blown up in a few days, and the dust source is exposed. However, the use of windproof dust-fixing agent does not exist at all. Dust suppressant can be sprayed by manual, mechanical or professional spraying stations (equipment, vehicles) and laying fixed pipelines. Manual spraying is suitable for sites with an area of less than 1000m2. Artificial pressure spraying device and push-pull spraying device are used to evenly spray the material area. Using push-pull sprinkler, mechanical spraying can be realized by a single person.
when the treatment area is 1000~5000m, it is recommended to use electric ejector with a range of about 15 m. the equipment is convenient to operate and has good dust reduction effect. When dust is suppressed on the surface of materials with a treatment area of more than 5000m2, vehicle-mounted or professional spraying vehicles can be used for spraying, with a range of 18-20 meters or even more. Fixed stockyards or moving trains, pulling trucks, conveyor belts, etc., can lay pipes and install sprinklers, also known as "spray stations", which automatically spray wine and dust suppressants to objects, with high efficiency and good dust suppression effect, but Large investment and long construction period. When dust is reduced in underground and dust workshops, an atomizing dust reduction spraying device can be selected. The device captures fine dust in the air through high-pressure ultra-fine mist, which can achieve a good atomizing dust reduction effect.
Dust suppressants can be widely used in coal and various metal and non-metal mining areas, mineral powder storage yards, coal and mineral powder transportation, mineral earthwork storage and unloading yards, building demolition, roads under construction, thermal power plants, Cement plants, iron and steel plants, metallurgical plants, dust workshops, artificial beaches and desertification areas and other places.
How to use dust suppressant:
the use of dust suppressant can generally adopt manual, mechanical or professional spray station and fixed spray system method, etc., the dust suppressant diluent evenly sprayed on the surface of the material or dust interval, can achieve the effect of dust prevention and dust reduction. The specific use method and dosage can be adjusted according to the site conditions in order to achieve the desired desired effect.
1. Spraying Equipment
small stock yard can be sprayed with backpack spray device or pesticide truck.
Large stockyards can be equipped with fixed spraying devices, and can also be sprayed by vehicle-mounted or professional spraying vehicles, with a range of 18~200m.
for mobile train and automobile transportation, it is necessary to build a dust suppressant spraying base station or purchase a mobile spraying vehicle to operate. the conveyor belt can be equipped with dry fog spraying equipment.
For dust reduction in underground and dust workshops, atomizing dust reduction spray devices can be installed. The device can capture fine dust in the air through high-pressure ultra-fine mist, thus achieving a good atomization dust reduction effect.
It should be noted that improper selection of dust suppressors will corrode the equipment or affect the quality of the spray.
2. dilution method
solid dust suppressant dilution:
It is recommended to install a multifunctional high-mixing liquid distribution system for the newly-built standard spraying base station to solve the long-term problem of powder in water.
Stir while adding water, the stirring time is 3-15 minutes, to ensure that the dust suppressant dissolves evenly, and the stirring time is slightly longer.
put the dust suppressant into the equipment container containing water in proportion, stir while putting it, and use it after stirring evenly.
3. spraying method
According to different dust suppression sites and microenvironments, the methods are different and the effects are also different. Please consult and request technical regulations from professional and technical personnel, and request on-site technical services if necessary.
