Traîtements de surfaceIndex. décimale : 668.4 Plastiques, vinyles Résumé : Successful adhesion, printing, coating or gasketing depends largely on substrate surface composition. Conventional solutions intended to provide plastic surfaces with hydrophilic properties are often difficult and expensive and based on solvents or other chemicals. Plasmatreat addresses these points with Openair-Plasma and PlasmaPlus. Note de contenu : - Effective activation of non-polar plastics
- Reliable protection for sensitive electronics
- Coating temperature-sensitive plastics without causing any damage
- Novel pretreatment and coating of an electrical component
- For every application – even temperature-sensitive components

Fragmentation
Industrie 4.0Le concept d’Industrie 4.0 correspond à une nouvelle façon d’organiser les moyens de production : l’objectif est la mise en place d’usines dites "intelligentes" ("smart factories") capables d’une plus grande adaptabilité dans la production et d’une allocation plus efficace des ressources, ouvrant ainsi la voie à une nouvelle révolution industrielle. Ses bases technologiques sont l'Internet des objets et les systèmes cyber-physiques.

Presses à injecterIndex. décimale : 668.4 Plastiques, vinyles Résumé : In order to achieve optimally resource-saving production and to minimize scrap, viscosity fluctuations must be detected and any required counteraction taken as early as possible. Viscosity fluctuations may be caused, for example, by differences in fiber content due to batch change, or by variations in granulate quality. With the latest version of its HiQ Melt application, Wittmann Battenfeld has created a means to reveal deviations already at the metering point. Note de contenu : - Melt monitoring of the melt quality
- Premium version : control system determines key figure for flow behavior
- Application example and conclusion
- Fig. 1 : HiQ Melt Monitoring keeps an eye on the recommended stroke utilization, which in turn affects the average residence time of the plastic melt
- Fig. 2 : The assistance system is the basis for a homogeneous preparation of the melt

OlfactométrieIndex. décimale : 668.4 Plastiques, vinyles Résumé : Odor is an important criterion when buying a car. Until now, manufacturers and suppliers have analyzed odor using the noses of trained persons. However, different persons judge the same odor differently. Instrumental analysis can measure odors objectively and rigorously. Odor can thus be globally standardized and subsequently efficiently reduced. Note de contenu : - The VOC-G method works differently
- Improving the odor of parts
- Measurement system analyses according to process 1 are also possible
- 7-day prediction by algorithm
- Fig. 1 : Structure of the olfactory pyramid, with graphical weighting of the individual intervals: Substances associated with the heart note are perceived more strongly than those from the other two regions
- Fig. 2 : The results of the VOC-G method and two panels for different materials show that the process provides very good results
- Fig. 3 : The measurements performed during production show that the deviations from the mean value are very small. The human panel, on the other hand, has no means of distinguishing such small nuances
- Fig. 4 : Checking of the 7-day prediction shows that the values agree very well with panel test values for materials that had been preconditioned for 7 days

Véhicules électriquesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Ball bearings in electric cars have to meet higher requirements than in vehicles with combustion engines. The trend towards smaller electric motors with higher speeds is further reinforcing this. A material alternative to the usual PA66 and PEEK is available for implementation. Note de contenu : - E-cars : fewer bearings, higher requirements
- Weight reduction drives up requirements

- Fig. 3 : SKF deep groove ball bearings using a polymer cage: The plastic bearing cage holds the rolling elements in the correct position. It must be resistant to mechanical and chemical stresses and ensure low friction
- Fig. 4 : Cage deformations (left) and cage failures (right) are caused by high rotational speeds and centrifugal loads, among other things
- Fig. 5 : The higher material stiffness of the PA46 reduced the cage deformations
- Fig. 6 : Fatigue strength (left) and strength retention after exposure to 150 °C hot oil (right) for glass fiber-reinforced PA66 and PA46.

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.
