Purpose:
ZWILCHEM Wetting Agent 10% Solution is designed for use as an additive to water in dust prevention, aiming to control harmful coal dust in underground workings of mining facilities. It is used to combat dust generation on longwall and roadway mining machines, dampen the area around mining equipment, and periodically wash down roadway roofs. It can be applied in underground mining workings in both non-methane and methane environments, in areas classified as "a," "b," or "c" in terms of methane explosion risk, as well as in areas classified as "A" or "B" in terms of coal dust explosion risk.
Characteristics:
ZWILCHEM Wetting Agent 10% Solution appears as a thick, milky, creamy liquid. It's a water-based solution of the active substance, which achieves excellent wetting properties at appropriate concentrations.
Product Properties:
ZWILCHEM Wetting Agent 10% Solution possesses properties that lower the surface tension of water. It has unlimited solubility in water. The surfactant in the formulation yields excellent results when wetting the dust generated during mining operations. The solution significantly reduces airborne dust hazardous to health in mining workplaces, decreasing the intensity of coal dust settling, which plays a crucial role in maintaining explosion-protection zones against the transmission of coal dust explosions. It reduces the risk of coal dust explosions by lowering the concentration of coal dust in the air. The application of ZWILCHEM Wetting Agent has a significant impact on working conditions and safety in underground mining operations.
Packaging:
ZWILCHEM Wetting Agent 10% Solution is available in 200-liter containers or other capacities as agreed upon between the producer and recipient.
