AbstractSodium-salt-based physical inhibitors reduce coal–oxygen interactions through moisture absorption and retention in the prevention of coal spontaneous combustion, but their wetting and spreading performance on coal surfaces can be further improved. To enhance the overall inhibition performance of sodium-salt-based inhibitors, the anionic surfactant sodium dodecyl sulfate (SDS) was introduced to modify the sodium chloride (NaCl) inhibition system, and the optimal composite inhibitor formulation was selected through experimental characterization and comprehensive evaluation using the entropy weight method. The results showed that SDS further enhanced the moisture-regulation capacity of the NaCl system.

They can't fly or swim, so why do their closest relatives appear on different continents?
