A micron is a micrometer, or one millionth of a meter (1/1,000,000 meters, or 1 x 10-6 meters). Mesh is a term used for a "screen" or "net" of some kind made of interlacing fibers or strands of some material. The mesh is a semipermeable "fabric" that will allow materials below a certain size threshold to pass through while stopping others. Mesh is also a term used in industry to speak to the particle size of irregularly shaped or granular material. For example, if we say "mesh 22" in regards to particle size, that means that particles that are about 1,000 microns in size and smaller will pass the screen, while larger particles will be obstructed and prevented from going through.
Because it stands for micron university.
ANSWERIn the case of polythene, gauge can be converted to thickness by dividing by four to get the thickness in micron or dividing by 4000 to get the thickness in mm. Here are some common examples:100 gauge = 25 micron = 0.025mm120 gauge = 30 micron = 0.03mm200 gauge = 50 micron = 0.05mm250 gauge = 62.5 micron = 0.0625mm400 gauge = 100 micron = 0.1mm
0.1 micron
Fiber mesh is the best way to go in my opinion! You save the cost of wire mesh , and installtion! And works better than wire.
Wire mesh should always be placed in a sidewalk. The wire mesh reinforces concrete that is only strong in compression. The concrete expands and contract in the summer and winter and the mesh will minimize cracking. It also helps when your neighbor drives his pick up truck across your sidewalk. Whenever a concrete road/bridge deck is placed reinforcing steel or heavy mesh is in it. The state agency doesn't do it unless it's needed.
177 micron
mesh 500 micron=31 inches=0.0012
No. of openings per square inch of wire mesh is specifies the mesh size and its again depends on wire dia also. If the number of openings per square inch is more then partical size which it can pass through the filter will be less. For example for 325 mesh size, where in 44 micron size of particle can get filter. In 200 mesh size 74 micron size of particle will get filter.
Mesh size is usually used in the US. It's just an alternative system used to describe the hole size. For example, 35 mesh (US) is the same as 0.5mm or 500 microns.
4 microns is smaller. 600 messh related to openings per square inch. The thickness of screen wire must be reduced from this opening size. For example, 500 mesh screens are rated to have an average 25 microns opening size. For 600 mesh this comes to approximately 21 microns.
1 micron > 0.5 micron
0.5 micron.
10 micron.
Ofcourse 23 micron is thicker than 11 micron.
90 micron.
2 MICRON
A 5 Micron is more fine then a 20 Micron, It means, if a particle has a thickness of 1 micron. only 5 numbers of particle can be passed through a 5 Micron filter at a time while 20 numbers of Particle can be passed through a 20 Micron filters. the 5 Micron is more efferent to the 20 Micron.
