Chrome oxide is
dichromium trioxide, typically known as Green Chrome
Oxide. It’s tiny hexagonal crystal having a color from
light green to dark green. It can be added into Ceramic Pigment or Chrome Green
Ceramic Pigment. It turns brown when receiving heated
up, after cooled down it still turns to green. The crystal is extremely tough
and most stable, even in the glowing state the hydrogen is passed by way of, it
still has no modify. It’s soluble in heated Potassium bromate remedy, slightly
soluble in acids and alkalis, practically insoluble in water, ethanol and
acetone. Its relative density is five.22, melting point about 2435℃ and boiling point 4000℃. It truly is irritating. It’s mostly
employed 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 supplies, or
catalysts for organic chemical synthesis, sun proof paint, abrasive supplies,
green polishing paste and special ink for printing paper funds. In addition to,
it may be used within the production of refractory for example high chrome
brick, chrome corundum brick. Then you could wonder why we use Chromium Oxide as
abrasive material?
The reason is
because the lapping tool and perform piece are soft, so in the polishing method
the abrasive material is suspended between the function piece and lapping tool,
mostly make use of the chemical action of plane polishing machine as well as
the operate piece surface to make a layer of very soft oxide film, and the
membrane at convex point can simply be rub out by abrasive material, within
this method we are able to get quite fine surface roughness, processing many
different steel, hardened steel, cast iron, copper and aluminum and their
alloys, tough alloy, ceramic, glass and some plastic items and so on. the
surface polishing of a perform piece is usually carried out following getting
polished; for manual surface polishing, the polishing agent have to be coated
on a polished plate, you ought to hold the perform piece for a straight line
reciprocating movement or "figure 8” motion, having polished for a
specific time frame, the work piece should be turned from 90 degrees to 180
degree to stop the inclination of a work piece.
The perform
piece of a surface polishing machine contacts having a grinding gear randomly,
the higher spot can be trimmed one another, the error is decreased gradually,
as well as the precision can also be improved, so it can be utilized to detect
the work piece, making targeted changes for the polishing position and grasping
the grinding time, making certain the precision from the dimension and shape,
acquiring reputable processing good quality; for the surfaces around the
operate piece that are to become grinded partly for example facet, square hole
and narrow slit, and so on., we are able to also hand-hold the grinding gear to
polish them, the surface on a sizable batch of simple components also can be
polished around the surface polishing machine, so it might widely utilized for
processing various higher precision surface in the single and little 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 perform piece, getting really high accuracy
plus a really low Ra worth, but we typically cannot raise the position accuracy
between the processing surface and also the other surface.
