In industrial production, the size and distribution of pigmented paint particles greatly affect the gloss, water permeability and storage stability of the finished paint. Scraper fineness gauges can be used to measure the fineness of these products, thereby improving product quality.
This issue mainly evaluates the Dutch TQC VF2111 scraper Fineness Meter. Let’s take a look at what is so special about this double-slot scraper Fineness Meter.
<1> The outer packaging of VF2111 is much smaller than that of some domestic products. Some domestic products use wooden boxes, while TQC’s scraper Fineness Meter uses leather cases. I feel that it is convenient to place or carry in my hand. a lot of. I don't quite understand why such a small thing has to be packaged in a big way. It's not just for appearance.
<2>VF2111 scraper Fineness Meter is 0-25μm, with an accuracy of up to ±2μm. It is a fully automatic product produced by a large TQC factory. It has 3 scales: micron μm, North PCU and Hegman H. It can be said that high precision is the main selling point of this product. Although some low-end products are also labeled as such, the actual test is like the gap between the Iphone 1300w pixel camera and the brand-name 1300w camera.
<3> The VF2111 scraper fineness gauge is made of Swiss 1.2085 tool steel, while the domestic one uses 4Cr13. Although 4Cr13 has high hardness after quenching, it is not as good in anti-rust and anti-corrosion capabilities. This can also be seen in VF2111 The fineness board is attentive in terms of materials.
<4>Many users have been asking whether it is better to have a double slot or a single slot, and why use a single slot. In fact, for testing work, repeatability is a very important indicator. Imagine that although a single slot can be scraped and tested multiple times, the external environment of each test is actually changing, such as speed, scraping time, external temperature, human strength, etc., will affect the accuracy. However, at the same time, at the same speed, at the same environment and under the same strength, two sets of data can be scraped once. On the one hand, it can reduce the number of tests by 50%, improve the test efficiency, and on the other hand, it is also a good operation comparison. So do you think double slots are good?
<5> The product design of TQC has always been highly appreciated by the author. This is not an empty talk. If you look at all the instruments and products of TQC on the North and South Tide, and compare them with our own domestic products, you will know that what the author said is true. Finally, let us enjoy the beautiful picture of this VF2111 scraper fineness gauge.
