This Fineness Meter is designed according to the standard coating inspection method issued by the Ministry of Chemical Industry: Fineness meter determination method GB1724-79. It can be used to test the fineness of pigments, fillers and impurities in paints and paint slurries, expressed in microns. .
Purpose: Determine the particle size of fuel filling and impurities in paints, paint slurries and inks
When using, first wash the scraper and scraper with gasoline, wipe them dry with cotton gauze, and then wipe them with deerskin. Dip a glass rod into a small amount of the paint to be measured that has been mixed (consistency consistent with the product standard) and drip it onto the scraper at an angle. In the deepest part of the groove, the amount of dripping should be slightly more than the appropriate amount to fill the chute. Then use the thumb, index finger and middle finger of both hands to place the scraper horizontally on the top of the scraper, so that the edge of the scraper vertically contacts the surface of the scraper. From the depth of the chute, Pull it towards the shallow place and immediately (within 5 seconds) observe the scale line where the particles in the tank are evenly exposed. This value is the fineness of the pigment and other particles in the paint.
1. The surface of the scraper and the edge of the scraper must not be bumped.
2. Wash and apply anti-corrosion oil after use.
3. Check the scraper regularly every year to check the flatness of the blade. If it does not meet the requirements, it should be repaired.
4. This instrument has one built-in scraper and two scrapers per box.
5. This instrument is suitable for use at a temperature of 22±1℃ and a Relative Humidity of 70% to ensure accuracy.
