METHOD FOR PREPARING EXPANDED POLYSTYRENE USING JACKET COOLING WATER WHICH CAN SAVE TIME AND ENERGY BY RAISING THE TEMPERATURE AND IMPROVE PRODUCTIVITY

摘要

PURPOSE: A method for preparing expanded polystyrene using jacket cooling water is provided to reduce waste heat energy, to save cycle time according to the heating of polymerization water by using cooling water of a jacket as water for suspension polymerization.;CONSTITUTION: A method for preparing expanded polystyrene comprises a step of using jacket cooling water used for the cooling of a polymerization reactor as water for polymerization of the expanded polystyrene. The polymerization reaction is a polymerization initiation reaction. The polymerization reactor is maintained at a temperature of 70~90 °C.;COPYRIGHT KIPO 2011
