AI Technical Summary
Existing flame retardants have problems with environmental pollution and insufficient timeliness in suppressing spontaneous combustion of coal. Traditional flame retardants may cause environmental pollution during use and their suppression effect is not long-lasting.
A synergistic composite system formed by potassium formate and surfactants (such as CTAB, SDBS, and SLS) is used to uniformly load the coal surface through supramolecular interactions, catalyze the self-decomposition of oxygen-containing groups in coal molecules, release carbon dioxide, dilute the concentration of combustible gases, and form a dense film for physical barrier, thereby achieving multi-stage synergistic inhibition of coal spontaneous combustion.
It improves flame retardant efficiency, enhances the effect of suppressing coal spontaneous combustion, reduces environmental impact, and has the characteristics of high efficiency, safety, and environmental protection. It can significantly extend the coal spontaneous combustion suppression time.
