TQC is a well-known instrument manufacturer in Europe, TQC wide groove Grindometer is a stainless steel single-groove Grindometer with a groove width larger than the general single-groove Grindometer, which has the advantage of high precision, reaching ±2 microns.TQC VF2120/VF2121/VF2122/VF2123Wide-groove scraper Fineness MeterThe material is made of Swiss 1.2805 tool steel, which is more wear-resistant and corrosion-resistant than general stainless steel.


There are four models of TQC wide single-groove Grindometer: VF2120, VF2121, VF2122 and VF2123.
rootVF2120/VF2121/VF2122/VF2123The Wide Groove Grindometer is a wide groove with 2 different parameters: Micron, Hegeman, and belongs to the graded slope design.
The physical properties of the final dispersion are often referred to as "fineness", which depends not only on the actual size of the individual particles, but also on the extent to which they are dispersed. Pigment fineness can be quickly measured using a pigment fineness plate.
To summarize: take a little more sample and pour it into the deep end of the groove, and use the matching scraper to scrape the measured sample to the shallow end of the groove at a suitable angle and smooth speed. After scraping, you can see that there are many rough particles on the surface of the fineness plate, which is the corresponding test point.
Specification of specific operations:
1 Wash the soaking wide groove scraper Fineness Meter and scraper with the specified solvent, and dry with cotton yarn.
2. Stir the specimen that meets the standard viscosity of the product with a grease knife thoroughly.
3. In the deepest part of the groove of the Grindometer, drop a few drops of the sample to fill the groove and slightly redundant.
4 Hold the spatula with the thumb, index finger and middle finger of both hands. It is placed horizontally at the upper end of the Grindometer, so that the scraper is perpendicular to the surface of the Grindometer, and the scraper is pulled from the deep part of the groove to the shallow part at an appropriate speed, so that the paint sample fills the groove and there is no excess paint left on the flat plate.
5. Immediately (no more than 5 seconds) pinch the Fineness Meter and tilt it so that the line of sight is at an angle of 15-30 degrees to the plane of the trench to observe the scale value of the evenly exposed particles in the trench, and the reading value is the fineness of the measured sample.

In addition to the fineness of paint, TQC wide groove scraper fineness Tester can also measure the fineness of many materials such as coatings, pigments, raw materials, plastics, printing inks, etc.
In the chocolate, ceramic, paper, food and other industries, TQC fineness gauge can also be used to test the fineness of products, and there are more application fields.
