文摘

Polycarboxylate with moderate length side chain shows excellent dispersion property. Dispersion relies on polycarboxylate adsorption thickness and density on coal. Both length of main chain and side chain can affect polycarboxylate adsorption. Adsorption layer thickness was measured to monitor polycarboxylate adsorbing on coal. Efficient dispersant can be screened by length ratio of main chain to side chain.
