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

Chrome oxide is dichromium trioxide, frequently named Green Chrome Oxide. It’s tiny hexagonal crystal using a colour from light green to dark green. It may be added into Ceramic Pigment or Chrome Green Ceramic Pigment. It turns brown when obtaining heated up, after cooled down it nevertheless turns to green. The crystal is incredibly challenging and most steady, even within the glowing state the hydrogen is passed by means of, it nonetheless has no modify. It’s soluble in heated Potassium bromate resolution, slightly soluble in acids and alkalis, virtually insoluble in water, ethanol and acetone. Its relative density is 5.22, melting point about 2435℃ and boiling point 4000℃. It truly is irritating. It’s primarily utilized for smelting metal chromium and chromium carbide, so we are able to typically see the fused chrome oxide. It may also be used for the colorants of enamel, ceramics, artificial leather, construction materials, or catalysts for organic chemical synthesis, sun proof paint, abrasive supplies, green polishing paste and particular ink for printing paper cash. Besides, it can be used within the production of refractory such as higher chrome brick, chrome corundum brick. Then you definitely might wonder why we use Chromium Oxide as abrasive material?

The cause is since the lapping tool and operate piece are soft, so in the polishing method the abrasive material is suspended between the perform piece and lapping tool, primarily use the chemical action of plane polishing machine along with the operate piece surface to make a layer of extremely soft oxide film, along with the membrane at convex point can effortlessly be rub out by abrasive material, in this technique we can get extremely fine surface roughness, processing a number of steel, hardened steel, cast iron, copper and aluminum and their alloys, challenging alloy, ceramic, glass and some plastic merchandise etc. the surface polishing of a perform piece is generally carried out after being polished; for manual surface polishing, the polishing agent have to be coated on a polished plate, you ought to hold the work piece to get a straight line reciprocating movement or "figure 8” motion, obtaining polished to get a certain time period, the function piece need to be turned from 90 degrees to 180 degree to stop the inclination of a function piece.

The operate piece of a surface polishing machine contacts having a grinding gear randomly, the high spot may be trimmed each other, the error is lowered progressively, as well as the precision can also be improved, so it can be employed to detect the perform piece, producing targeted changes towards the polishing position and grasping the grinding time, making sure the precision in the dimension and shape, obtaining reliable processing good quality; for the surfaces around the work piece which are to be grinded partly like 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 components may also be polished on the surface polishing machine, so it could extensively utilized for processing various higher precision surface in the single and tiny batch production, and may be utilized for mass production, may be carried out the cutting length amongst 0.01|¨¬m and 0.1|¨¬m of a function piece, obtaining really higher accuracy as well as a very low Ra value, but we generally can not raise the position accuracy amongst the processing surface along with the other surface.
