Urea Formaldehyde (UF) Glue Plant

The Urea Formaldehyde (UF) technology provided by SL TEC is based on the
traditional alkali-acid-alkali process. It consists of three steps:
Hydroxymethylation--under neutral or slight alkali conditions, urea and
formaldehyde have hydroxymethylation reaction; Polycondensation-- condition the
pH of the reaction solution to slight acid, the reaction mixture have
polycondensation to reach a certain molecular weight; Temperature Reducing--
condition the pH of the reaction solution back to slight alkali, and reduce its
temperature to room temp. to get the preliminary condensed solution.
Our Urea-Formaldehyde Glue Technology has the following features:
1. The Glue Workshop has been designed in a 2-floor steel structure, and
installation materials incl. pipe, pipe fittings and etc. will be saved by 20%.
2. Urea is directly sent by the Urea Conveyor from the first floor to the
reactor, the urea hoisting is saved, thereby the labor strength is largely
reduced, i.e. the material
