About: Grindometer

An Entity of Type: device, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A grindometer is a device used to measure the particle size of suspensions, typically inks such as those used in printing, or paints. It consists of a steel block with a channel of varying depth machined into it, starting at a convenient depth for the type of suspension to be measured, and becoming shallower until it ends flush with the block's surface. The depth of the groove is marked off on a graduated scale next to it. The suspension to be tested is poured into the deep end of the groove, and scraped towards the shallow end with a flat metal scraper. At the point where the depth of the groove equals the largest particles in the suspension, irregularities (for example pinholes in an ink sample) will become visible.

dbo:abstract
  • Ein Grindometer ist ein Gerät zum Messen der Körnigkeit einer Pigmentpräparation (Paste) oder eines Lackes. Es wird zumeist aus Edelstahl gefertigt. Die Messung des Pigment-Ausreibgrades mit dem Grindometer (eng. to grind = mahlen) nach Hegman wird in DIN 53 203 bzw. DIN EN 21 524 und ISO 1524 beschrieben. Zur Prüfung wird eine Probe von etwa 0,1–0,5 ml zuerst auf das tiefere Ende der keilförmigen Vertiefung des Grindometers aufgetragen und anschließend mit einer Rakel (Haarlineal) ausgestrichen. Dann wird mit dem Auge anhand der Skala diejenige Schichtdicke bestimmt, bei der der Lackfilm infolge auftretender streifen- oder punktförmigen Spuren rau aussieht. Damit kann man die Größe und Anzahl von körnigen Partikel oder Agglomeraten bestimmen. Vorteil der Methode ist, dass die Messung sehr rasch (innerhalb weniger Minuten) durchgeführt werden kann und nur sehr wenig Probenmaterial verbraucht wird. Damit kann man Prozessschritte bei der Produktion von Lacken und Pasten verfolgen. (de)

At the point where the depth of the groove equals the largest particles in the suspension, irregularities (for example pinholes in an ink sample) will become visible. The advantages of this method are that it uses a small sample and gives a very quick indication of the high end of the particle size distribution, allowing production processes to be followed in real time. The following standards are relevant on conjunction with the use of grindometers: ASTM D 1210, ASTM D 1316, JIS K 5600-2-5, ISO 1524, EN ISO 1524, BS 3900-C6 (en)
