Confirmation of Amorphicity Having carried out the melt processing procedure it was necessary to confirm that the polymer sample was amorphous. Qualitatively this may initially be done by visual inspection using a microscope, since amorphous PEEK does not contain crystalline regions it is translucent whereas semi-crystalline PEEK is opaque. Quantitative analysis of the amorphicity of PEEK was carried out using the analytical techniques described in Chapter 3.4.1. Polymer Processing of PEEK with Supercritical Carbon Dioxide A Parr Instruments Company high-pressure bomb reactor (LTR) was used to process the amorphous PEEK samples with scCO2. The amorphous PEEK samples, contained within their 40 μl aluminium DSC pans, were loaded into the LTR and the vessel was sealed. A liquid withdrawal CO2 cylinder provided by BOC Ltd was used to supply liquid CO2 at 5 MPa from the cylinder to a Jasco PU-1580-CO2 delivery pump. The CO2 delivery pump was used in conjunction with the reactor furnace to generate the conditions necessary. Once the required conditions were obtained Swagelock valves, SS-3NRM4 and SS-0VM2-A-BKB, were used to seal the reactor and maintain the internal pressure. Coolant maintained at 269 K was pumped, using a Watson-Marlow 302 Peristaltic Pump at 110 rpm, from a PolyScience Chiller to the agitator cooling jacket. A design of experiments (DOE) approach was used to investigate the effects of supercritical carbon dioxide on the crystallinity of amorphous PEEK samples. The DOE used was a full 84PDF Image | Supercritical Fluids and Their Application to the Recycling of High-Performance Carbon Fibre Reinforced Composite Materials

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
