Investigation of the recyclability of powder coatings

Powder Technology, 2011
Abstract 100% recyclability is one of the major advantages of powder coating. However, it can never be achieved in reality. Coating powders, especially finer powders with particle size below 30 μm, were found to have much worse flow performances after recycling from electrostatic spraying so as to decrease the recyclability. Therefore, this study was

Sintering of Powders From Fiberglass Recycling

Volume 2: Processing, 2014
Sintering is a typical process for metal powders which can be effectively agglomerated by a solid state diffusion mechanism. Polymer powders are less sensible to this kind of mechanism because of the lower molecular mobility. Anyway, such applications have been mentioned about sintering of thermoplastic powders in the scientific literature.

Recycling of Waste Epoxy-Polyester Powders for Foam Production

International Journal of Manufacturing, Materials, and Mechanical Engineering, 2011
This paper proposes a new foaming technology (solid-state foaming) to produce structural foams from waste thermosetting resins. The proposed technology is easy and does not require specific and expensive equipments. Solid tablets are produced by cold compaction of resin powder, and foam by heating in an oven.

Tailored Method for Recycling Degraded Perovskite Powder

Small
Abstract Perovskite materials have attracted considerable attention owing to their outstanding optoelectronic properties. This study presents a method of recycling perovskite powders for optoelectronic applications. Two main strategies are employed: a simple perovskite recycling method for slightly degraded powders and a cation ...
