Origin of mesh
Many customers often buy coating rods in NBCHAO, and the units provided are "mesh". For example, I want to find 100 mesh coating rods, which is actually difficult for customer service personnel. We know that the mesh is actually used in the powder coating industry to refer to the number of holes on the screen per square inch. The higher the mesh, the smaller the particle size. However, there is actually no unified technical standard for the "mesh number" at home and abroad, and the conversion between mesh number and particle size (μm) is not uniform in various countries . Therefore, it is recommended that customers choose coating rods according to the ( wet film thickness calculator ) provided by NBCHAO .
A conversion table between mesh and micron
For another industry experience, you can refer to the "Mesh Size and Granularity Comparison Table", which is based on the Taylor standard. For other American, British and Japanese standards, please refer to the Internet.

micron concept
μm
Micron
Micron is a unit of length, symbol [micron]. 1 micron is equivalent to one millionth of a meter (this is the meaning of "micro").
Conversion relationship
------------------------------------------------ --------------------------------
1 000 000 picometer (pm) = 1 micron (μm)
1 000 nanometer ( nm) = 1 micron (μm)
1 micron (um) = 10-6m = 1000 nanometers (nm)
1 millimeter (mm) = 10-3m = 1000 microns (um)
0.001 mm (mm) = 1 micron (μm)
0.000 1 centimeter (cm) = 1 micrometer (μm)
0.000 01 decimeter (dm) = 1 micrometer (μm)
0.000 001 meter (m) = 1 micrometer (μm)
0.000 000 001 kilometer (km) = 1 micrometer (μm)
0.000 001 micrometer (μm) = 1 picometer (pm)
0.001 micrometer (μm) = 1 nanometer (nm)
1 000 micrometer (μm) = 1 millimeter (mm)
10 000 micrometer (μm) = 1 centimeter (cm)
100 000 micrometer (μm) = 1 decimeter (dm)
1 000 000 micrometers (μm) = 1 meter (m)
1 000 000 000 micrometers (μm) = 1 kilometer (km)
The conversion between the above mesh number and micron (μm) is based on personal experience and online information reference, please distinguish by yourself.
