Metallographic sample preparation is not easy, alloy sample preparation is not easy, precious metal sample preparation is not easy, composite materials, electronic materials, polymers&hellip& Hellip; It is not easy to prepare samples of materials. The grinding of samples of all these materials should start with the grinding of metallographic abrasive paper. Can we make sample preparation easier by selecting a suitable metallographic abrasive paper?

The answer is yes, yes!

Personal experience&mdash& Mdash; What we do is the metallographic analysis of printed circuit board. The coarse grinding of the sample has always used ordinary metallographic abrasive paper. The process is generally 180 \. This year, we all use imported metallographic consumables, and use qmaxis metallographic abrasive paper imported from the United States for rough grinding, which not only saves more than half of the grinding time, but also makes the grinding surface more flat, and the deformation layer and scratch removal are ideal, laying a very good foundation for subsequent polishing.

After repeated use for a period of time, we compared the data of grinding the same sample with the original ordinary metallographic abrasive paper and qmaxis metallographic abrasive paper, as shown in the figure below. You can see at a glance.

Indeed, selecting a good metallographic sandpaper can make sample preparation easier. In the case of higher technical requirements and more emphasis on quality, it is more cost-effective to select imported metallographic sandpaper with better quality. Although the direct cost of purchasing metallographic sandpaper is higher, it is more durable. One piece can be equivalent to 3-5 pieces of ordinary sandpaper. In addition, it can shorten the sample preparation time and improve the quality of sample preparation, All these aspects are cost-effective. Therefore, we have reason to believe that selecting high-quality sandpaper such as qmaxis metallographic sandpaper can make sample preparation easier.

The qmaxis metallographic abrasive paper we selected is from qmaxis testing (Nanjing) Ltd., which is his own brand. It is imported with original packaging and has excellent water resistance. Silicon carbide grinding medium, manual and automatic grinding can be used. It is really good to use, and the service is also good! No matter what kind of material you do for metallographic analysis, metallographic sandpaper is often used for grinding samples. Don't settle for it. Choose an easy-to-use one that saves time and effort. If you need it, you can directly contact Kemei to buy it, Baidu search“ Qmaxis test” You can find it.
