Taille des particulesIndex. décimale : 667.9 Revêtements et enduits Résumé : Copper pyrithione is used in antifouling coatings as a (0-biocide. A study of leaching rates showed that particle size had finie effect on the loss of copper pyrithione itself, but its presence could modify the leaching rate of the copper present itr other forms. Differing results from an earlier experiment suggest a way to optimise leaching rates. Note de contenu : - How biocide leaching rates were measured
- Leaching rates show less variation than expected
- Copper pyrithione may increase copper leaching

Taille des particulesIndex. décimale : 667.9 Revêtements et enduits Résumé : Wet grinding as a process has been around for hundreds of years, with technology constantly refining what's opssible in terms of efficiency and quality. 2020 sees the introduction of a step-change in technology that arguably takes the industry to the limits of the physics of what's possible. But that's not the end of the story ; a new digital horizon could continue to drive progress for the next decade. Note de contenu : - The 5 fundamentals of wet grinding
- 1. Uniform particle distribution is the ultimate goal
- 2. Different material types require different amounts of energy
- 3. Different forces are required to reduce sizes in different materials
- 4. Target properties require different approaches
- 5. The smaller the beads, the more efficient the process
- The history of wet milling
- A step change in technology for 2020
- 1. New technology enables even smaller beads
- 2. Introduction higher flow rates
- Entry-level dashboards to improve decision-making
- Next level statistics and insights
- The ultimate goal - Smart algorithms to minitor and optimise the process

Taille des particulesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The characteristics of emulsions used in a tannery for leather greasing are presented in this study. Emulsions have been prepared from five commercial greasing [fatliquor] products as 10% emulsions which were tested in the pH range from 4 to 8.
Mean particle size, fraction number and dispersion coefficients of tested systems are presented. Based on the results obtained it was found that samples with emulsions containing lanolin and samples with emulsions containing mixtures of synthetic and natural oils showed the best stability.Note de contenu : - Materials - Determination of mean particle size and particle distribution of fat emulsions

Taille des particulesIndex. décimale : 667.2 Colorants et pigments Résumé : Pigment dispersion quality in pastes and paints may be tested by one of several different techniques. Probably the most common method in labs and plants is taking readings with a grind gauge, usually the Hegman type (ASTM D1210). The main reason for doing this for pastes usually is to see whether the dispersion process has reached the required end point for that pigment. Another reason would be to find out whether the dispersion equipment was adequate to achieve the target reading in a reasonable length of time. Hegman readings of 6 and 7 correspond to particle sizes of 25 and 12.5 mm, respectively, yet the average pigment particle size will be a fraction of that, perhaps as little as 1/10th. With a grind gauge, we only see the boulders, the largest particles (aggregates, agglomerates). Beginners find grind gauges frustrating to use and their precision is poor, but experienced users can produce rapid, repeatable, and meaningful results.
