Production and application of sodium salt of naphthalene sulfonate polymerized with formaldehyde compound as a flocculating and dehydrating aid

摘要

According to the present invention, a kind of reticular structure is provided, napsylate formalin polymer has high supplement condensation efficiency, and in low residual monomer, it is through the following steps that control molar rate is condensing; By minimizing monomer removal residual monomer using organic acid and hydrogen peroxide and causing to stablize; And control a certain amount of sodium hydroxide and potassium hydroxide which is put into neutralisation, reticular structure is produced as dewatering aid. ;The 2015 of copyright KIPO submissions
