A certain amount of foaming agent and water vapor are retained in the beads after pre delivery of foam mechanical equipment. When leaving the machine, the beads will be condensed into liquid, and the liquid foaming agent will be dissolved in polystyrene, which will soon reduce the pressure in the bubbles. Negative pressure (partial vacuum) will appear in the bubbles. The beads are very soft and easy to deform. So when supplying air, try to avoid excessive wind pressure, the inner wall of the air duct should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid static ignition. The transmission speed should not exceed 8m/s to avoid damage to the beads.
