New mixing section blends painted regrind.A new mixing section being developed by Robert Malloy, chairman of the Plastics Engineering Dept. at the Univ. of Massachusetts-Lowell, reduces the size of paint particles in reground painted plastics, yielding improved mechanical properties. The patented mixer mixer, either of two electronic devices in which two or more signals are combined. In the type of mixer used in radio receivers, radar receivers, and similar systems, a signal is translated upward or downward in frequency. (U.S. 7021816, 2006), nicknamed "the grater," is designed to blend recycled materials like painted TPO (Twisted Pair Only) Refers to the use of twisted pair wire when other options are available. For example, a TPO suffix at the end of 3com Ethernet adapter model numbers indicates the card has only an RJ45 connector. bumpers and multilayer barrier packaging films. The mixer has long axial axial /ax·i·al/ (ak´se-al) of or pertaining to the axis of a structure or part. ax·i·al adj. 1. Relating to or characterized by an axis; axile. 2. channels that are closed at the discharge end, forcing the melt over a land with fine cross-wise grooves (resembling a cheese grater) to reach the discharge channel. The "grater" reduces paint particle size Particle size, also called grain size, refers to the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. by 50%, Malloy says. It can use one groove size or progressively finer grooves and can be of any length. Malloy is now developing a spiral version. After extrusion with the "grater," painted TPO regrind shows ultimate elongation elongation, in astronomy, the angular distance between two points in the sky as measured from a third point. The elongation of a planet is usually measured as the angular distance from the sun to the planet as measured from the earth. of about 20% vs. 12% without the grater or 34% for unpainted TPO.
