Dispersion applications

In practical applications, dispersion calculations need to be performed in topographically complex environment. Thus, solid obstacles intervening in the area dispersion should be counting in the computations. In previous validation works, it has been proved that CFD codes constitute powerful tools for complex terrain dispersion simulation providing high accuracy results with excellent visualization capabilities, which can be helpful in quantitative risk analysis applications [55]. The dominating mixing mechanism between...

The physical interpretation of the load factors is that a liquid flow should be transported through the interface, and this transport is augmented by the density difference and decreased by the continuous phase viscosity. The liquid load factor accounts for transport of both phases through the interface, while the other two only transport the applicable dispersed phase. Flence, the liquid load factor is in line with the new separator design philosophy proposed by Polderman et al. (12, 15), while the oil and water load factors are in line with the dispersion layer theory developed by Jeelani and Flartland (16-20) (for the corresponding dispersed phase). 

This application is based on the most advanced dispersion technology for PAni in water. In contrast to other approaches, nonfunctionalized polyaniline has been used as the raw material. This makes it possible to start with a commercially available polyaniline powder (Ormecon) instead of special polyaniline derivatives for different applications or dispersion media. It shows, furthermore, the generally applicable dispersion concept. The application on printed circuit boards is a long-term and high-end application and is specified on the basis of the long-term stability of our product. 

Dispersion. Most of the flow regimes of interest in chemical and bioprocess engineering are of turbulent flow. This turbulent flow is characterized by the presence of fluctuations, and not only in the direction of the flow. These fluctuations produce an increment on the rate of mass transfer. In most industrial applications, dispersive mass transfer is more relevant than diffusion. For example, this is the most important mechanism in combustion (think flames) and distribution of the pollution (think chimney smoke). 

Dispersant effectiveness is defined as the amount of oil that the dispersant puts into the water colnnm versns that which remains on the surface. There are many factors that inflnence dispersant effectiveness sea energy, oil composition, state of oil weathering, rate of dispersant application, dispersant type, temperature, salinity of the water, etc. The...

Second in importance come high-gloss applications, where cardboard or paper is laminated to a film in order to obtain a particular optical effect shiny or matt, for instance. The third area contains a variety of applications, e.g. flat antennas, microcircuits, insulation materials, under the heading technical laminations. Most of the time, these laminations involve metal foils or plates. While food packaging and technical laminations rely mostly on reactive two-component adhesive systems - solvent-based or solvent-free, based on polyurethane chemistry (for some applications dispersions are also used they can be made up of polyurethanes, acrylics or natural raw materials like latex and casein) - high-gloss... 

Dispersion polymerization is a convenient procedtue to form larger solid particles. Uniform-sized polymer beads with diameters between 0.1 and 10 pm are finding an ever increasing role in a number of coatings, electronics, microelectronics, biomedical, and information technology applications. " Particle size control and nauow size distribution are key parameters for most of these applications. Dispersion polymerization is generally recognized as a type of... 

The joining of wood by adhesives is widely used in many fields of application. This comprises structural joints, glued-laminated timber, and coatings. In industrial processes, wood is structurally connected by formaldehyde-containing melamine or phenol resorcin resins which cure by polycondensation. Due to the very thin adhesive layers and the minimized formaldehyde content, the expected incorporation into the surrounding air is considerably less than the specified thresholds. In manually operated applications, dispersions of acrylates and polyvinyl acetate as well as urethanes are usually used to bond wood (Richter and Steiger 2005).
