Using Peroxides to Optimize Process Control for Styrene Emissions

摘要

Several studies in the past have suggested that it is possible to dramatically reduce the over all loss of styrene vapors during the laminating process by simply increasing the thickness of the laminate, thus reducing the number of 'open" layers in the laminate schedule. The elimination of an "open surface" step reduces the amount of time the laminate surface is exposed for the styrene to evaporate. The major problem to implementing this procedure in the past was the exotherm generated by the thick thermo mass of the laminate. It is now possible to reduce this exotherm with specialty blended peroxides, thus making this technique practical to use in most laminating shops to reduce styrene emissions without costly mechanical controls. A secondary bonus in this process change is a reduction in labor equal to the number of process steps eliminated.
