Do You know why We Use Chromium Oxide as Abrasive Material?

Chrome oxide is dichromium trioxide, frequently named Green Chrome Oxide. It’s tiny hexagonal crystal having a colour from light green to dark green. It can be added into Ceramic Pigment or Chrome Green Ceramic Pigment. It turns brown when getting heated up, right after cooled down it nevertheless turns to green. The crystal is incredibly difficult and most steady, even within the glowing state the hydrogen is passed through, it nonetheless has no change. It’s soluble in heated Potassium bromate solution, slightly soluble in acids and alkalis, virtually insoluble in water, ethanol and acetone. Its relative density is five.22, melting point about 2435℃ and boiling point 4000℃. It really is irritating. It’s mainly utilized for smelting metal chromium and chromium carbide, so we are able to frequently see the fused chrome oxide. It could also be utilized for the colorants of enamel, ceramics, artificial leather, building components, or catalysts for organic chemical synthesis, sun proof paint, abrasive components, green polishing paste and unique ink for printing paper funds. In addition to, it may be employed in the production of refractory including higher chrome brick, chrome corundum brick. Then you might wonder why we use Chromium Oxide as abrasive material?

The reason is since the lapping tool and perform piece are soft, so inside the polishing process the abrasive material is suspended between the work piece and lapping tool, primarily use the chemical action of plane polishing machine as well as the function piece surface to create a layer of extremely soft oxide film, as well as the membrane at convex point can easily be rub out by abrasive material, in this method we are able to get quite fine surface roughness, processing a variety of steel, hardened steel, cast iron, copper and aluminum and their alloys, tough alloy, ceramic, glass and a few plastic items and so forth. the surface polishing of a operate piece is usually carried out soon after getting polished; for manual surface polishing, the polishing agent should be coated on a polished plate, you ought to hold the operate piece to get a straight line reciprocating movement or "figure 8” motion, possessing polished to get a particular period of time, the function piece ought to be turned from 90 degrees to 180 degree to stop the inclination of a operate piece.

The work piece of a surface polishing machine contacts using a grinding gear randomly, the high spot might be trimmed each other, the error is reduced steadily, and the precision can also be improved, so it can be utilized to detect the perform piece, generating targeted changes for the polishing position and grasping the grinding time, making sure the precision in the dimension and shape, obtaining dependable processing good quality; for the surfaces on the function piece which are to become grinded partly including facet, square hole and narrow slit, and so on., we can also hand-hold the grinding gear to polish them, the surface on a sizable batch of straightforward parts may also be polished on the surface polishing machine, so it can broadly utilized for processing a variety of higher precision surface in the single and modest batch production, and may be employed for mass production, could be carried out the cutting length amongst 0.01|¨¬m and 0.1|¨¬m of a work piece, acquiring very higher accuracy plus a really low Ra value, but we typically can't raise the position accuracy in between the processing surface and the other surface.
