This is not Sun Wukong's 72 changes, nor is it Sichuan Opera's face changing, but rather a result of technological innovation.


Metallographic sandpaper without adhesive backing has been widely used because it is more economical. But the trouble and inconvenience were also handed over to our users.


Usually, metallographic sandpaper without backing is placed directly on the working aluminum plate and then fixed with sandpaper clamps. Its drawback is that the flatness of the entire sandpaper is difficult to control&# 8217& Flash; The levelness of the grinding tool is precisely the prerequisite for the quality of grinding and polishing. The user's working hours are quite expensive, and the waste rate of sample preparation is still high. In addition, long-term and high-frequency direct contact with the working aluminum plate is a high-risk and costly operation method. If there are scratches on the working aluminum plate or if the fixing device is loose, the cost of replacement can completely devour the economy of sandpaper without adhesive backing.


More important than economy is the surface quality of sample preparation. Unless you are an experienced driver of grinding and polishing, samples prepared with non adhesive sandpaper are often inferior to metallographic sandpaper with adhesive. Continue to drag down the issue&ndash& Flash; When polishing, the consumption of polishing cloth and polishing fluid is more, and the polishing time is also more, so it is really not cost-effective to calculate.


QMAXIS (Kemai, USA) has found&quo; Transforming&# quo; Solution&flash& Flash; Magnetic Rubber Disc.


RubberDisc, with magnetic on one side and adhesive on the other side, is used in conjunction with magnetic discs for pasting metallographic sandpaper without adhesive.

When using, first stick the magnetic disc onto the working aluminum disc. There are two purposes: one is to protect the working aluminum disk with magnetic disks, and the other is to modify the mechanical rotating aluminum disk into the basic disk of the magnetic system.


Assuming that the grinding process for preparation consists of four steps, it requires Grit180/P180, Grit320/P400, Grit500/P1000, and Grit1000/P2500 without adhesive sandpaper. Take out the magnetic rubber disc RubberDisc, remove the non adhesive layer on the side with adhesive backing, and then attach the edge of the non adhesive sandpaper to the edge of the magnetic rubber disc. Gradually drop the sandpaper in opposite directions, and use your fingers to draw a zigzag shape on the surface of the sandpaper, expel air, and compact the sandpaper. The sandpaper without adhesive turned beautifully and transformed into sandpaper with magnetic backing.


Next, attach the magnetic side of the RubberDisc to the magnetic disc and complete the combination with the magnetic disc system.

The reason why QMAXIS chooses flexible rubber discs instead of hard metal discs is because rigid metal discs are prone to deformation and defects such as bumps or burrs on the edges. Flexible rubber discs have better adsorption performance than hard metal discs, and their corrosion resistance and durability are also significantly better than metal discs.


The magnetic rubber disc can repeatedly stick thousands of sandpaper sheets, with four steps of grinding and 4000 sandpaper sheets. Sandpaper without backing is approximately 27% cheaper than sandpaper with backing. When 75 sheets (less than 10%) of sandpaper are used in each of the four steps, the additional cost of the magnetic disc and magnetic rubber disc is covered, and the remaining 90% is pure savings.


27% * 90%=24%, which is a saving mathematical model by changing the sandpaper without backing to magnetic backing sandpaper and applying it to magnetic systems.


And what about the saved user labor costs due to more convenient and efficient disc swapping? What about the performance created by high-quality surfaces achieved through better flatness of sandpaper? It also makes managers uncontrollably happy. This completely confirms the old saying: If you want to do good work, you must first sharpen your tools!

The RubberDisc, innovatively launched by QMAXIS (USA) for users, magically transforms sandpaper without backing into magnetic backing sandpaper, even more impressive than sandpaper with backing!
