Quantitative water and steam foaming agent will retain in the beads that pressurized expanding by eps foam mechine , after get out of the machine, condensed into a liquid, liquid foaming agent and dissolve polystyrene foam product machine in ethylene, the bubble pressure decreases quickly, negative pressure appears inside the bubble (some vacuum), the bead is very soft, easy to deformation. So when use the automatic blocks moulding machines, don't make the air pressure too high, the wind pipe should be lubricated, bending radius as large as possible (some also reduce the bump resistance), the pipeline should be a good conductor of electricity, it is necessary to complete the line ground, to prevent electrostatic ignition, the transmission speed should not exceed 8m/s. In order to prevent the beads can't be damaged.


The beads just out of eps foam mechine is wet, because the air is absorbed when just get out of the eps foam mechine, they suddenly cold, resulting in honeycomb hole make foaming agent bubble condensation vacuum bubble hole formed, so the beads are necessary to advance in a period of time, on the one hand is to make them dry,on the other hand make the air into to the beads eliminate the negative pressure,even out the pressure inside the bubble and the external pressure, avoid the bubble collapse, in roder to the beads with elastic.


The EPS beads just get out of eps foam mechine by the time must be boring, cooling and bubble pressure stable process,what is called ripening. Improved pre curing beads in the molding process, further swell the bead fusion and bead elasticity,and the quality of EPS product.
