Overview
The Grindometer is an instrument used for the measurement of particle size distribution or particle size of Coatings, inks, pigments, cosmetics, etc. The China QXD-100 double-channel grind fineness gauge is a standard double-channel Grindometer with a range of 0~ 100 μm, Graduation is 5 μm, and the groove size is 140 × 12.5mm. It is made of zirconia Pottery and porcelain, and is specially used for testing Fineness of heavily corroded materials.
Features
1. Using Zirconia Pottery and porcelain material, with high Hardness and Abrasion Resistance, improve measurement accuracy and Repeatability.
2. Zirconia Pottery and porcelain have good chemical Stability and are not easily affected by corrosion or chemical reaction.
3. Zirconia Pottery and porcelain High Temperature Stability, suitable for high temperature measurement environment.
4. Pottery and porcelain zirconia insulation performance is good, can be used in electrical and electronic fields.
Principle
Spreader the sample on a flat substrate, and then scraping the material using a scraper, to evaluate the particle size and dispersion of the sample according to the film thickness or particle distribution of the residual material on the scraper.
Applications
Coatings, pastes, plastics, inks, paper
Steps
1. Spreader the sample on a flat substrate.
2. Use a scraper to scrape the material flat.
3. Observe the film thickness or particle distribution of the residual material on the scraper.
4. Assess the sample particle size and dispersibility according to the residue situation.
Notice
• Dedicated to testing of heavily corrosive materials, do not use on non-corrosive materials.
• Clean the surface of the scraper in time after use to keep it flat and stable.
• Avoid prolonged exposure to non-high temperature environments to maintain material performance.
• Pay attention to insulation performance to ensure safety in electrical and electronic applications.
