The shot is to use high-speed rotation of
the impeller to small steel shot or small iron balls thrown out high-speed hit
parts of the surface, so it can be removed parts of the surface of the oxide
layer. Also, steel or iron pill hypervelocity impact parts of the surface,
causing parts of the surface of the crystal lattice distortion, the surface
hardness increased, on the parts surface cleaning method, shot blasting is used
to the casting surface cleaning or on parts of the surface hardening.
Sand is the use of the quartz sand blown
out of a high speed on the parts surface cleaning method of compressed air. The
factory is also called blowing sand, not only to rust, but also by removing
oil, it is very useful for coating. Commonly used in parts of the surface rust;
on parts of the surface modification (market to sell the small wet sand
blasting machine is the use of sand is usually corundum, the medium is water);
in steel structure and application of high-strength bolt connection is a more
advanced method, due to the high strength connection is using a combination of
friction surface between the transmission of force of, so the combination of
surface quality requirements is very high, then you must use sandblasting on
the binding surface for processing.
Shot blasting and blasting of workpiece to
clear the whole decontamination, to preparing for the order, that is, to ensure
the procedure requires the roughness of, also some for surface consistency,
shot peening on the workpiece have strengthening effect, sand blasting is not
obvious. General shot for small ball, sand is quartz sand. According to
different requirements, mesh points.
Almost every day in the precision casting,
sandblasting, shot blasting. Shenzhen precise powder metallurgy has 8 years of
industry experience, for a variety of product surface processing, there is a
professional degree and familiarity with, ZCMIM also to provide you with a
variety of difficult solution, ZCMIM welcome you to understand!
