Surface Tension Phenomena of Plastics - Investigation and Application
Surface tension and the related phenomena, as for example work of adhesion, wetting, and spreading pressure, play an important role in many areas of plastics engineering such as bonding, assembly injection moulding, painting and coating, and frictional, sliding and wear behaviour.
The interrelationships between the surface and the derived interfacial tension phenomena and mechanical properties, such as for gluing, assembly injection moulding, and the influence of additives (dispersion, flow behaviour, adhesion) on compounding and use of highly filled polymers, was shown and correlated in this study. In addition, the surface tension measuring techniques for polymers, in the liquid and solid state, were compared. As a result, guidelines for the application of these methods could be established. In regards to the applications mentioned above, the influence of surface roughness, temperature, surface morphology, and pressure on surface tension of materials in the liquid and solid state was analyzed.
The true surface tension of solid state bodies is discussed in many citations. However, since no definite answer is given, a solution for this problem was suggested as a result of the studies conducted. Therefore, the importance of the usually neglected receding angle was identified and included in our conclusions.Lesen Sie die deutsche Zusammenfassung auf Kunststoffe.de
