When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the, the depth profile is measured by mils – thouhs of an the metric system, the micron(one millionth of a meter) is used.
commercial silica is used in the building products industry. Whole grain commercial silica products account for approximately of the projected sales. Ground Silica Products. Ground silica with sizes ranging from 40 to 250 microns is used in plastics, rubber, polishes, cleansers, paints, glazes, textile fibreglass, and precision castings.

Feb 23, 2012· Government standards for HEPA filters for silica dusts say it must remove % of particles greater than micrometer from the air. The fliter that comes with that unit appears to stop nothing below 1 micron. It is the sub micron particles that are of REAL concern.
The term ''Mesh'' is used to describe the size of an abrasive particle. In some instances, such as with Aluminum Oxide Grit or Silicon Carbide Grit, a single number is does not mean every particle in that product is exactly that size but rather than mesh size indicator is approximately the mean or average size of the range of particles in that grade.

So, beyond 325400 mesh, we usually describe particle size in "microns." What is a micron? A micron is another measurement we use for measuring particle size. A micron is onemillionth of a meter or one twentyfive thouh of an inch. This table is adapted from a post made by Ken Kosanke to the PML and previously published in a PGII Bulletin.
Nov 06, 2000· How much silicosis people will develop depends on genetics and degree of exposure to respirable quartz, which is silica dust ranging from .2 or .3 microns in diameter to 5 microns, says Levin. Particles larger than this are trapped in upper airways and smaller particles are largely blown out because they act like a gas, he says.
