Overview
The PUSHEN triple-channel Grindometer is a professional instrument for the measurement of particle fineness, widely used in paints, coatings, inks, food and other industries. The Fineness Gauge is designed with a flat steel block with a groove on the surface. The depth is gradually changed from MAX Maximum to zero, and the particle value is read in scale units.
Features
1. A variety of models are available, covering different ranges such as 0-25μm, 0-50μm, and 0-100μm.
2. Using triple-channel design, the groove width is 12mm, which is convenient for multiple sets of measurements.
3. Support multiple scale units, including μm, Hegman and MIL, to meet different standard requirements.
4. The size of the scraper is 175 x 65 x 15mm, making it compact and easy to operate.
Principle
The surface of the Fineness Gauge is provided with grooves, and the depth is gradually changed from MAX Maximum at one end to zero at the other end. By scraping the sample through the grooves, the particle fineness value is directly read according to the scale depth corresponding to the residual particle position. The scale units include Hegman and MIL, for example, 0 Hegman corresponds to 100 μm, 4 Hegman corresponds to 50 μm, 8 Hegman corresponds to 0 μm; 1 MIL corresponds to 25.4 μm.
Applications
Paints, paints, inks, food
Standards
GB/T 1724、GB/T 6753.1、GB/T 13217.5、ISO 1524、ASTM D 333、ASTM D 1210
Steps
1. Prepare the sample to ensure uniform and bubble-free.
2. Place the sample at the beginning of the Fineness Gauge groove.
3. Drawdown blades are used to scrape through the grooves at a constant speed to fill the grooves with samples.
4. Immediately observe the residual position of particles in the groove and read the fineness value corresponding to the scale.
5. Clean Fineness Gauge for next use.
Notice
• Make sure Fineness Gauge and Drawdown blades are clean and drying before operation to avoid contaminating the sample.
• Maintain a uniform speed when scraping the sample to avoid pausing or affecting the Measurement accuracy too quickly.
• When reading the scale, it needs to be carried out in an environment with sufficient rays of light to ensure accuracy.
• Clean the instrument in time after use to prevent corrosion or errors caused by sample residues.
• Select the appropriate model and scale unit according to the Application to ensure compliance with relevant standards.
