TQC VF2120 wide-channel Grindometer 0~15μm with calibrated certificate

VF2120

Wide-channel Fineness gauge

Grindometer Wide Channel DIN-ISO 0-15 µm

TQC of the Netherlands is a well-known instrument manufacturer in Europe. The TQC wide groove scraper Fineness Meter is a stainless steel single groove scraper Fineness Meter with a groove width larger than that of ordinary single groove scraper Fineness Meters. It has the advantage of high precision. Reach ±2 microns. TQC VF2120/ VF 2121/ VF 2122/ VF 2123 wide groove scraper fineness gauge is made of Swiss 1.2805 tool steel, which is more wear-resistant and corrosion-resistant than ordinary stainless steel.

Introduction

TQC wide single-slot Grindometer has four models: VF2120, VF2121, VF2122, and VF2123. The fineness plate is made of hardened stainless steel. The surface is fine, smooth and easy to maintain. It can be operated by hand during use.

This VF2120/ VF 2121/ VF 2122/ VF 2123 wide groove Grindometer is a wide groove with 2 different parameters: micron, Hegeman belongs to graded slope design.

Overview of fineness testing

During the fineness testing process of pigments, the pigments need to be ground into finer particles for dispersion in fluid equipment. The physical properties of the final dispersion are usually called "fineness", which not only depends on the actual size of the individual particles, but also depends on them. The extent to which it is dispersed. The pigment fineness can be quickly measured using the pigment fineness board.

Instructions

To summarize: Pour a little more of the sample to be measured into the deep end of the groove, and use the matching scraper to scrape the sample to be measured toward the shallower end of the groove at an appropriate angle and at a steady speed. After scraping, you can see many rough particles on the surface of the fineness plate, which are the corresponding test points.

Standard specific operations:

1. Wash the wide groove Grindometer and scraper with the specified solvent, and wipe them dry with cotton gauze.

2. Mix the sample that meets the standard viscosity of the product thoroughly with an oil knife.

3. In the deepest part of the groove of the scraper Fineness Meter, drop a few drops of the sample so that it can fill the groove with a little excess.

4. Hold the spatula with the thumb, index and middle fingers of both hands. Place it horizontally on the upper end of the scraper Fineness Meter, make the scraper perpendicular to the surface of the scraper Fineness Meter, and pull the scraper from the deep part to the shallow part of the groove at a suitable speed, so that the paint sample fills the groove without leaving any excess on the plate. Excess paint.

5 Immediately (no more than 5 seconds) hold the Fineness Meter horizontally and tilt it so that the line of sight is at an angle of 15-30 degrees to the groove plane and observe the scale value where the particles in the groove are evenly exposed. The reading value is the fineness of the sample being measured. Spend.

Wide groove Grindometer meets standards

ASTM D1210, ASTM D1316, DIN 53203, DIN EN ISO NF21524, FTMS 141 a M.4411.1 ISO1524,NFT 30 046

Applications

In addition to measuring the fineness of paint, the TQC wide groove scraper Fineness Meter can also measure the fineness of many materials such as coatings, pigments, raw materials, plastics, printing inks, etc.

TQC fineness plates can also be used to test the fineness of products in chocolate, ceramics, paper, food and other industries, and there are more application areas.
