Foam Dust Suppressant
I. Application Principle The foam dust capture and dust reduction technology has been widely used in coal mining. It utilizes dust removal water pipes and compressed air pipelines, mixed with water in a certain ratio, and through a special foaming device, compressed air is introduced to generate high-multiplicity foam, which is sprayed onto the dust source through nozzles. The foam acts on the dust through good coverage, wetting, and adhesion, fundamentally preventing the spread of dust and effectively reducing the concentration of dust in the air. Compared with other wet dust suppression methods, the water usage is reduced by 50-80%, and the dust removal efficiency is more than three times higher than that of spray watering.
II. Technical Features of Foam Dust Capture Agent
1. The foam can cover the cutting drum of the mining machine without gaps, allowing the cutting to be completed within the foam body, fundamentally preventing the spread of dust;
2. After the liquid forms foam, the total volume and total surface area increase significantly, increasing the collision probability with dust and enhancing the dust reduction efficiency;
3. The liquid film of the foam contains a specially made dust capture agent, which can greatly reduce the surface tension of water and quickly increase the speed at which dust is wetted;
4. The foam has good adhesion, and dust will be quickly adhered to the foam after contact;
5. For high gas mines, the foam covering the cutting drum can effectively suppress sparks generated by cutting, preventing gas and coal dust explosions;
6. The small water consumption avoids the subsidence of the mining machine caused by the large water consumption of water mist dust removal, improving work efficiency;
7. The foam dust capture agent wrapping the mining face can also play a certain role in lubrication and cooling, providing some protection for mining equipment;
8. The main equipment is fixed with strong magnets, making installation, disassembly, and maintenance convenient.
III. Performance Characteristics of Foam Dust Capture Agent:
1. Water-soluble product, environmentally friendly, non-toxic, and harmless, causing no secondary pollution to the environment;
2. High-efficiency concentrated formula, low usage concentration, significant dust suppression effect, and long-lasting;
3. Polymer product, long-term use does not corrode equipment and does not require cleaning after use;
4. Easy to operate, highly soluble in water, low solution viscosity, efficient atomization, and even spraying;
5. Low usage, concentration can be as low as 0.5-1%;
6. Since the main components of the product are organic compounds, there are no residues or adverse effects on the environment.
IV. Application Range of the Product Suitable for dust disaster prevention in confined spaces such as coal mine working faces, belt conveyor transfer points, and tunnel construction sites.
1. Dust production on coal mining working faces. The main dust-producing processes on coal mining working faces include coal falling, loading, transportation by the mining machine, hydraulic support movement, transportation transfer, manual coal breaking, blasting, and coal release at the coal mouth, etc.
2. Dust production on tunneling working faces. The main dust-producing processes on tunneling working faces include mechanical rock (coal) breaking, loading, blasting, coal liver transportation transfer, and anchor spraying, etc.
3. Dust production at other locations. The anchor spraying site during tunnel maintenance, coal loading and unloading points, etc., also produce high concentrations of mine dust. Especially the instantaneous mine dust concentration at the coal loading and unloading site can sometimes reach the coal dust explosion concentration limit, which is very dangerous.
4. Other application fields Coal and mineral mining, transportation, loading and unloading, stacking; open material yards; sand and gravel plants; quarries; building demolition, civil construction and surrounding roads, under-construction road lines, distribution stations, storage and transportation stations, coal storage yards, slag yards; coal mines, mines, ports, docks, power plants, cement plants, steel mills, coke plants, coal washing plants, smelting plants, metallurgical plants, dust workshops, and other areas and places prone to dust generation.

Bleaching Enhancer belongs to the category of chelating dispersants. It is resistant to strong alkalis and high temperatures and is an environmentally friendly substitute for EDTA, DTPA, and NTA.
Widely used in various textile dyeing and papermaking auxiliaries, fabric pretreatment such as desizing, scouring, bleaching, and mercerizing processes, hydrogen peroxide bleaching stabilizers, paper mill bleaching enhancers, detergents, washing agents, and water treatment agents, etc.
Performance Features:
Appearance: Light yellow transparent liquid
Active content: 10%±1%
pH value: 8.5 (1% aqueous solution)
Density: 1.06g/cm³ (20°C)
Alkali resistance: 220g/L
The bleaching enhancer for pulping has an extremely strong capturing and dispersing effect on metal ions. It can chelate with various polyvalent metal ions such as calcium, magnesium, zinc, and iron over a wide pH range, forming more stable water-soluble complexes. This prevents adverse consequences such as reaction precipitation scaling, ineffective decomposition of bleaching agents, and pulp re-yellowing caused by metal ions during the pulp bleaching process. At the same time, it has the effect of protecting pulp fibers and increasing the dispersibility of bleaching liquids.
1. It can effectively inhibit the catalytic decomposition of hydrogen peroxide and hypochlorous acid bleaching agents caused by metal ions, improve bleaching efficiency, save bleaching liquid, and reduce bleaching costs.
2. It has a strong capturing and dispersing effect on Fe3 ions, avoiding the reaction of Fe3 ions with phenolic groups in the pulp to form dark-colored complexes, protecting fibers, improving pulp brightness, and reducing pulp re-yellowing.
3. It can effectively prevent polyvalent metal ions such as calcium and magnesium from undergoing chemical reactions to form precipitates during the pulp bleaching process, thus preventing system equipment and pipeline scaling, and can gradually remove the original scaling of the bleaching system.
4. It has a certain dispersing ability and can improve the dispersibility of sodium silicate, thereby reducing the amount of sodium silicate used.
5. It protects pulp fibers and prevents the damage to fibers by the NaOH peeling reaction.
6. Compared with traditional DTPA, it has good environmental friendliness.
Product Application:
This product is widely used in the bleaching of chemical, mechanical, and de-inked pulp with hydrogen peroxide and hypochlorous acid as bleaching agents.
Application:
Add continuously to the system according to the process ratio or using a metering pump, the dosage is generally 1~5 kg/ton of dry pulp, but it should be used according to specific situations to obtain the best effect.
