A Cool New Way To Extrude PS Foam.An Austrian packaging producer may be the first to use a static-mixing heat exchanger heat exchanger Any of several devices that transfer heat from a hot to a cold fluid. In many engineering applications, one fluid needs to be heated and another cooled, a requirement economically accomplished by a heat exchanger. in place of a tandem cooling extruder for PS foam sheet. The processor won't let its name be used, but the mixer/cooler is a new small "cooling reactor," CSE-XR Model DN200, from Fluitec Georg AG in Winterthur, Switzerland. This short cylindrical cyl·in·dri·cal adj. Of, relating to, or having the shape of a cylinder, especially of a circular cylinder. device runs at 4650 psi PSI - Portable Scheme Interpreter with a pressure drop of 580 to 1160 psi. In 20 sec it cools the melt from 500 F to foaming temperature, Fluitec says. The melt that exits the die reportedly shows thermal homogenization homogenization (həmŏj'ənəzā`shən), process in which a mixture is made uniform throughout. Generally this procedure involves reducing the size of the particles of one component of the mixture and dispersing them evenly to within 1[degree] F. Fluitec is now building a larger model, DN300, for PS foam testing. |
