Taille des particulesIndex. décimale : 667.9 Revêtements et enduits Résumé : The author details just a few of the methods and instruments available that are able to measure the size of fine particles down to 0.003 micrometers in diameter.
The methods of measuring fine particle sizes have seen major developments in the past few decades. This applies to fine solids, but especially to latex particules. The oldest method for separating solid particles by size was the use of a sieve. Later, a range of sieves with different meshes was used.
Woven sieves are available for measuring sizes of particles from several millimeters to 20 micrometers, although some care is needed in the latter case to ensure that the sieve does not become distortes. Shape has a strong influence on particule size by sieving.
Originally, the only method of measuring the size of latex particles was by direct microscopic observation, which could give a maximum magnification of about 400. The phase microscope with oil immersion increases magnification to a maximum of about 600. The latex is diluted at least 10 times before a drop is placed on a slide and a cover glass is pressed over it. The assumption here is that particles in latex are essentially spherical, but this is noy always true.
Simple observations can show whether particles in any latex are unisized or have a variety of sizes and shapes. In dealing with solids, size and shape have more significances. The minimum size which can be observed directly is about 0.4 micrometers.Note de contenu : - Modern methods

UltrasonsIndex. décimale : 668.4 Plastiques, vinyles Résumé : Metrology - Thermal homogeneity of the polymer melt is essential for the production of high-quality injection molded parts. Previous attempts to accurately measure the real temperature differences in the injection molding process have failed on account of challenging metrological boundary conditions. Researchers have now found a way of using the temperature dependence of ultrasonic speed to develop methods for determining the radial and axial temperature gradients in the space in front of the screw.

PhotostabilitéIndex. décimale : 746.6 Impression, peinture, teinture Résumé : Paper-based heritage objects on exhibition are typically framed using a transparent glazing material such as glass or acrylic. This often makes the task of measuring their light fastness a difficult one since cultural institutions may have unframing restrictions, especially for large-format objects. However, a testing programme recently conducted at the National Museum in Krakow has revealed that in certain cases it is possible to obtain colorant stability information directly from a framed object. Microfading testing results are reliable if the distance from the object to the protective glazing is adequate to allow proper illumination and collection of reflected light. This paper presents a case study of six large-format pastels on paper by Stanisław Wyspiański, one of the most outstanding and versatile artists at the turn of the twentieth century in Poland. Some of the orange and pink areas showed higher sensitivity to light with fading rates that remain within the Blue Wool 1-2 range. The objects have been classified according to the light sensibility of their colorants, and this information has allowed development and implementation of exhibition guidelines that serve to minimise the degradation associated with museum illumination. In addition, scientific imaging, microfading data and computer analysis of the images have allowed virtual representation of the potential colour changes that these artworks may experience as a result of uncontrolled and long exposure to gallery illumination.
