Overview
This fineness meter is designed according to the standard Coating inspection method promulgated by the Ministry of Chemical Industry, the fineness meter measurement method GB/T6753.1-86 and ISO1524-83 standards, which can be used for inspection of Paints and paint pulp. The fineness of pigments, fillers and impurities and other particles is expressed in microns.
Features
1. Adopt double-channel design to provide two scraping grooves
2. The range is 0~ 25μm, and the scale unit is μm
3. The scraper and drawdown blade are made of stainless steel to ensure durability
4. The size of the scraper is 175mm * 65mm * 13mm, and the groove size is 140 * 12.5mm.
5. The drawdown blade size is 90 * 40 * 6mm, easy to operate
6. Groove ratio of 1:3000, Graduation of 5 μm
7. The flatness of the upper plane of the scraper is 0.003mm, and the flatness of the bottom plane of the inclined groove is 0.003mm.
8. The plane flatness of the two edges of the drawdown blade is 0.002mm.
9. Scraper upper plane surface roughness Ra ≤ 0.2, chute surface roughness Ra ≤ 0.5, drawdown blade two edge finish Ra ≤ 0.2
Principle
The fineness meter scrapes the sample on the groove of the scraper through the drawdown blade, and measures the fineness of the pigment, filler and impurity particles in the Paints and paint paste according to the distribution of the particles in the groove. The results are expressed in microns.
Applications
Paints inspection, paint paste inspection
Standards
GB/T6753.1-86、ISO1524-83
Steps
1. Prepare the sample to be tested
2. Place the sample in the scraper groove
3. Use the drawdown blade to scrape the groove evenly
4. Observe the distribution of particles in the groove
5. Read the fineness value in microns
Notice
• Ensure that the scraper and drawdown blade are clean and free of contamination before use
• Keep the drawdown blade perpendicular to the plane of the scraper during operation
• Avoid drawdown blade damage and affect Measurement accuracy
• Clean the instrument in time after measurement to prevent sample residue
Store in a drying environment to avoid corrosion
