Performance in Product

The production of plutonium metal by both fluoride and oxide reduction is well established at Los Alamos. The subsequent purification of this metal by electrorefining is now being performed in production on a 6-kg batch scale. The objective is the production of high-purity plutonium metal. 

These examples show how quality standards are established in production and how quality improvements may be sought. When PV is used as a QA tool, these quality standards enhance the potential for maintaining a validated process during routine production. They then will be the basis for QA confidence [4] that the quality function is being adequately performed in production. 

Laboratory cooking procedures seldom simulate production residence times, temperatures and shear stresses. A promising laboratory formulation may perform less well when scaled-up, due to dissimilar processing and adverse, unanticipated changes during abusive storage. For that reason, special care is required in scale-up to maintain product viscosity and texture. Final starch selection is often based on performance in production equipment.

Even when the material purchased meets all of the buyer s bid specifications, the material or product may not be well suited for its intended use. This is especially Traerifpht hate rock. Phrosphate rock is quite variable in phosphate content from deport to deposit and in quantities of impurities that drastically affect the rock s performance in production of nitrophosphates, phosphoric acid, superphosphates, and ammonium phosphates. Thus, the material purchased may not be what was initially wanted. Even though this material may meet all the stated specifications, it is possible for unspecified contaminants or impurities to affect the performance of the materials in subsequent processing or the crop response in finished fertilizers. 

The successful introduction of aerogel materials into the consumer markets depends on the value that the aerogel materials bring to the product as compared to the insulating materials currently being used. This is basically a cost versus benefit analysis. Is there a market for improved thermal performance in products that need thermal insulation The answer for this is quite simply, yes, but the more important question is, what is the price that consumers will pay for this improved insulation Knowing the answer to this question will allow consumer product manufacturers and marketers to produce and sell products successfully. 

Resin production is performed in production plants that may be integrated in larger facilities or that are completely standalone units. In some cases, UPES resins are produced in multipurpose plants where other resins, like alkyds and saturated polyesters, are also produced. The market demands a large variety of resins in order to suit the wide variety of end market applications and conversion technologies applied. This is reflected in the resin production facilities being able to produce a variety of products on the basis of different raw materials (recipes), process conditions and to target final specifications. Order size and packaging demand (bulk, container, and drum) add to the complexity of the production facility. 

The initial conditions must be specified in the reactant coordinates, while any final state analysis, needed for instance to determine the quantum state distribution of the products, must be performed in product coordinates. 

Li et al. reported a new application of synchrotron VUV photoionisation MS in thermal decomposition studies of polymers, and displayed its good performance in product analysis helpful to understand the thermal decomposition mechanisms of PVC and PS, extensible to other synthetic polymers. Pyrolysis products of PVC and PS formed at different temperatures were identified by the measurement of photoionisation mass spectra at different photon energies. The experimental results showed the differences of the pyrolysis product pool of PVC at different temperatures, and established that the thermal decomposition process occurred into two steps the low-temperature step to form HCl and benzene, and the high-temperature stage to form several large aromatic hydrocarbons. For the thermal decomposition of PS, four reaction categories were determined [181]. 

Several kinds of chemical tests, mechanical tests and non-destructive inspections were performed in production for the material of the primary coolant pipe. In manufacturing of piping system, pressure test and several kinds of non-destructive inspections were performed.
