What is the function of additives? Describe its physical properties? Answer: The function of additives is to improve the fluidity and stability of the coal slurry. As a surfactant, it has three functions: (1) wetting the coal particles to facilitate the mixing of water and coal ； (2) Disperse larger gelatinous coal particles ； (3) Provide cations as the equilibrium ions of the hydration film to act as electrolytes. Its physical properties are as follows: The additive has a dispersing effect; it can adjust the hydrophilicity and charge on the surface of coal particles, reduce the hydration film on their surface as well as the forces between the particles, thereby allowing the water trapped on the surface of the coal particles to escape.

The function of the additive is to improve the fluidity and stability of the coal slurry. As a surfactant, it has three functions: (1) to wet the coal particles, facilitating the mixing of water and coal; (2) to disperse larger, agglomerated coal particles; (3) to provide cations that serve as balancing ions for the hydration film, thereby playing an electrolytic role. Its physical properties are as follows: The additive has a dispersing effect; it can adjust the hydrophilicity and charge on the surface of coal particles, reduce the hydration film on their surface as well as the forces between the particles, thereby allowing the water trapped on the surface of the coal particles to escape.
The function of additives is to improve the fluidity and stability of water-coal slurry. As surfactants, they have three functions: a) to wet the coal particles, thereby facilitating the combination of water and coal； b) Disperse larger gelatinous coal particles ； c) Provide cations as the equilibrium ions of the hydration film to act as electrolytes. Its physical properties are as follows: The additive has a dispersing effect; it can adjust the hydrophilicity and charge level of the coal particle surface, reduce the forces between the hydration film on the coal particle surface and ions, and cause the water trapped on the surface of the coal particles to overflow.
