三聚氰胺甲醛树脂用作絮凝剂的探讨

Study of Melamino-formaldehyde resin as Flicculant

研究了反应物配比、反应时间、反应温度对产物密胺甲醛树脂絮凝效果的影响，找出了絮凝效果最佳的反应条件为：三聚氰胺／二甲胺／甲醛（ｍｏｌ比）＝１／９／（４～７），反应温度７０℃及反应时间２ｈ。

In this paper, such conditions of melamino-formaldehyde resin(MF) used for a flocculant as the reactant concentration, reaction time and temperature were studied. And the best synthetic conditions were found,mel amine/dimethylamine/formaldehyde (mol)=1:9:(4～7), reaction temperature 70℃, reaction time 2h.
