Germany Erichsen232-25 Fineness Meter, coating inks fineness detection

Erichsen232 Fineness Gauge Test Principle:

It is used to measure the fineness of the coating, which scrapes the test paint into a wedge, finds the position where the particle size of the paint is greater than the height of the wedge-shaped groove by visual inspection, and reads the depth of the groove at the position of the dividing line between smooth and uneven on the surface of the sample, which is the fineness value of the coating.

The design of the German Erichsen 232 Fineness Meter:
The 232 fineness gauge is made from a single piece of hardened steel that has been specially treated to ensure dimensional stability, and two precisely machined wedge-shaped grooves are cut into the hardened steel. The height of the tank is μ m on one side of the tank, the corresponding Hegman scale (HS) on the other side, other scales can also be customized on request, and the conversion relationship between the commonly used fineness units is shown in the following chart: Standard #232 has a fineness measurement range of 15 / 25 / 50 / 100 μ m, and a straight-edged scraper for scraping is included in the scope of delivery.

Measurement process:

Pour enough test material into the deep end of the wedge-shaped groove, be careful not to create air bubbles, hold the scraper, perpendicular to the fineness plate and the groove, and smoothly scrape the material towards the narrower end of the groove, this stroke should be completed in 1-2 seconds. 

The evaluation should be performed within 3 seconds of scraping, with a view perpendicular to the groove and a Viewing Angle of 20-30 degrees, to identify the location of particle aggregation or scratches, which corresponds to the depth of the groove that corresponds to the fineness of the test material.

Erichsen232 fineness gauge maintenance:

Immediately after use, it should be cleaned with dissolving, and do not use sharp and hard objects to remove the remaining paint. The straight edges used by the scraper are subject to continuous wear, so the minimum force should be applied during operation, and after a certain period of time it needs to be checked, the scraper is placed on the level (e.g. along the longitudinal direction of the fineness plate), and then checked according to the principle of light transmission.
