Retsch Product Overview
the sample - Particle Measurement
In this special issue of “the sample” we present the entire product range of particle analyzers on offer from Retsch Technology.
-
Asphalt Emulsions
Asphalt-aggregate roads have traditionally been made by an asphalt-coated aggregate that has been hot-mixed at a central plant. Asphalt emulsions have made the manufacturing, storage, and road construction a much simpler process. Asphalt emulsions are droplets of asphalt dispersed in water with the aid of an emulsifying agent. Particle size of the asphalt droplets is critical to stability and application performance.
-
Chocolate
Particle size measurement of chocolate samples is a vital factor in producing a consistent and attractive final product. Several stages of manufacturing are controlled by particle size and the particle size of cocoa powder used in chocolate affects color and flavor strength.
-
Coffee
The flavor and strength of coffee depends on the coffee beans selected, the roasting process, the brewing method and the fineness of the ground coffee used. In commercial grinding, the process is well developed and monitored by the use of laser diffraction particle size analyzers. The speed, consistency, and ease of use have made it the most popular method for process control.
-
Iron Oxides
Iron oxides are used in a wide variety of forms and have many uses. The majority are used as pigments or for their magnetic properties. Particle sizing in each of these applications is critical to final product performance.
-
Milk Homogenization
Milk is an emulsion that is homogenized to reduce the average particle size, which improve its consistency and extends shelf life. The homogenization process is expensive and careful control of the process can improve quality and consistency and reduce operating costs.
-
Organic Pigments
A general definition of a pigment could mean any substance that alters the color of a material through selective color absorption. Pigments are used to color a broad range of products including ink, paint, cosmetics, fabric and food.
-
Paper Coating Chemicals
Paper is manufactured from wood fiber slurries, fillers, sizing agents, and coatings. Sizing agents are used to provide resistance to the absorption of moisture or to eliminate ink feathering and bleed through. Selection of the specific sizing agents, fillers or coatings will depend on the final application for the paper.
-
Particle Sizing of Sediments
Particle size analysis of a geologic area can reveal critical information about the region’s formation, history and climate. Particle characterization is an important tool for studying changes in geology and climate over time, mode of formation, and current environmental effects related to pollution transport, erosion, and sediment transport.
-
Powder Coatings
Powder coatings are alternatives to paints that are comprised of a resin and a pigment. The powder is sprayed on the part and attracted by the electrostatic charge applied to the part. The item is then heated in an oven to cure the resin and form a solid layer. Particle size is important to provide the optimum surface finish and minimize process waste.
-
Solid Oxide Fuel Cell Materials
Solid oxide fuel cells (SOFC’s) offer the potential to greatly reduce man’s dependence on coal and oil for the production of electricity. They are clean, quiet and efficient. At the heart of these devices lies a complex combination of polycrystalline ceramic materials, each having to meet a particular set of structural and electrochemical requirements.
-
Synthetic Diamond Abrasives
Diamond is one of the hardest materials known to man. As such, it makes an ideal abrasive for applications such as grinding wheels, hones and dressing tools. The finer grades (less than 325 mesh/44 microns) are called diamond micron powders and are used in a powder or slurry form for a variety of polishing and lapping applications.
-
Zirconium Oxide
Zirconium oxide is a common metal oxide ceramic with a wide range of uses due to its thermal stability, strength, chemical resistance, and optical properties. In most applications, particle size is an important parameter in the final product performance.
