Processing agents

To improve processing and to plasticize the mbber compound, numerous processing agents have been used over the years, eg, petroleum and ester plasticizers, resins and tars, Hquid mbber peptizers, peptizers, fatty acids and derivatives from vegetable oils, and polyethylene and hydrocarbon waxes. 

Ester plasticizers are used mainly in very polar elastomers, such as neoprene and nitrile mbber, to improve low or high temperature performance or impart particular oil or solvent resistance to a compound 5—40 parts are commonly used (see Plasticizers). Resins and tars are added to impart tack, soften the compound, improve flow, and in some cases improve filler wetting out, as is the case with organic resins in mineral-filled SBR. Resinous substances are also used as processing agents for homogenizing elastomer blends. 

The costs of an intervention have to be compared with the results of this intervention (Drummond et al. 2004). These results can be outputs, outcomes, and impacts (Fig. 2). An output is the direct result of a production process. Agents of production (resources) are transformed to generate a certain commodity or service (output). For instance, equipment, reagents, and the knowledge of a laboratory technician are used to perform a certain resistance test. Other examples of outputs are contacts, admissions, or prescriptions. 

The Demo II tests generally confirmed the performance and efficacy of the GPCR process for the treatment of the waste streams from the process. However, problems with the agent detection method hampered a full evaluation of the process, and some concerns were raised about the selection of materials of construction for the processing agent. 

NOTE Two SCWO units are for processing energetics hydrolysate (slurried with dunnage), two SCWO units are for processing agent hydrolysate, and one SCWO is available for either service five interchangeable trains total.

Secondary wastes include SDS, DPE suits, spent carbon, dunnage, slag, and ash. In the modified baseline process, the plan is to process agent-contaminated dunnage and DPE suits through the MPF. These materials were reported to be successfully processed in the MPF at JACADS and, therefore, should be processed similarly at Pueblo. The throughput rates remain to be demonstrated. SDS was processed in the LIC afterburner at JACADS, which supports the likelihood that SDS can be treated in the MPF afterburner in the modified baseline process, but this remains to be proven (Thompson, 2000d).
