EPE foam extruder machine after the beads retain a certain amount of foaming agent and water vapor, when the machine, condensation into a liquid, liquid foaming agent and dissolved in polystyrene, so that the pressure in the bubble quickly reduced, bubble negative pressure, beads are very soft, easy to deformation. Therefore, when the wind is delivered, try not to make the wind pressure too large, the inner wall of the air pipe should be as smooth as possible, and the bending radius should be as large as possible. The pipe should be a good conductor of electricity, and the whole line must be grounded to avoid electrostatic ignition. The transmission speed should not exceed 8m/s to avoid bead damage. Just the EPE beads of pretest machine material is wet, after release from pretest machine, due to absorb air, a sudden encounter cold, causing condensation of foaming agent to make bubbles in the honeycomb bubble hole hole forming negative pressure, so the beads must be placed a period of time after the pretest, on the one hand makes it dry, make it into the air to eliminate negative pressure on the other hand, the balance of internal pressure and external pressure of bubble hole, Avoid bubble hole collapse, so that the bead has elasticity.Just out of EPE pre-expander EPE beads after a certain period of drying, cooling and bubble pressure stability process is called maturation. Curing can improve the further expansion, interbead fusion and elasticity of pre-formed beads in the forming process, which is beneficial to improve the quality of EPE products.In the process of curing, the beads are cooled by air, and the foaming agent and water vapor of the pores in the bubble hole are condensed into liquid, so that the negative pressure is formed in the bubble hole. At this point, the air will permeate into the interior of the bubble through the bubble membrane, so that the pressure in the bubble is balanced with the external pressure, which will make the beads have elasticity after the pre-release.Curing can be divided into natural curing and pressure curing two methods. In cool, dry, ventilated conditions, the natural gas is called natural maturation. The pre-maturation beads after natural maturation are inflated by adding gas to a certain pressure in a sealed container, which is called pressurized maturation.Features of EPE machine1.
