| titleOfInvention | Process for Production of Polyolefin Foam Beads |
| abstract | The present invention relates to a method for producing polyolefin foam particles, and an object of the present invention is to provide a method for producing polyolefin foam particles in which excess foaming agent can be recovered at a low equipment cost and a running cost, and water can be reused with little energy input.n n n The method of the present invention comprises the steps of: (a) a foaming agent penetrating step of injecting the resin particles, water and blowing agent into the penetration tank and heating with stirring to infiltrate the blowing agent into the resin particles; (b) a gas separation step of injecting water in which the water or the blowing agent is dissolved into the permeation tank to discharge and recover the blowing agent existing in a gaseous state in the upper space of the container; (c) a liquid separation step of injecting a high pressure gas into the permeation tank to discharge and recover the water in which the blowing agent is dissolved; (d) the resin particles are discharged into a reduced pressure expansion tank together with the high pressure gas filled in the high pressure vessel in the step (c), followed by foaming under reduced pressure.n n n According to the present invention, in addition to the addition of an aqueous solution storage tank to recover the excess blowing agent, there is no need for many additional equipment such as a cooler, a compressor, a separator, etc., and it is possible to recover and reuse high temperature water, thereby reducing equipment costs and operation costs. . |
