Synthesis And Characterization Of Fire Retardant Paper Via Phosphorylation

This study was undertaken to produce a fire retardant paper from the nation’s local raw material, Acacia mangium using the phosphorylation process. There are three main stages conducted in this study. The first stage of the treatment requires the pulp to be treated in an aqueous solution containing...
