Why over-wet steam is not allowed during EPS beads expansion process?
EPS production technology: Pre-expansion
-Why over-wet steam is not allowed during EPS beads expansion process?
-
Over-wet steam lacks enough heat, with excessive water.
-It can cause expanded EPS beads' density to be too high and cause problems when EPS beads are transported.
-
Condensate water should be removed before steam enters the pre-expander.
-Install a drain valve at the bottom of the steam pipe.
