What about the key points for selecting flour mesh?...

The easiest way is to use a vernier caliper. Its caliper is 1 inch / 25.4mm, calculate or count how many holes, this method is actually suitable for 100 mesh or less, if you use more thannylon mesh sieve 100 mesh, it is not very suitable. Now let's talk about the following two methods to teach you the test.

1 is the use of a magnifying glass, a simple magnifying glass can be used for products below 200 mesh, and a high-magnification screen requires a graduated magnifying glass. The scale of the graduated magnifying glass is generally 1 mm, and the number of meshes within 1 mm can be counted, multiplied by 25.4, even if the sieve The number of meshes. Generally, the high mesh 

screen is preferably a digital magnifying glass with a scale, and has the functions of photographing and ranging.

2 One method is to use a fabric warp and weft density mirror. As long as the density mirror is parallel to the warp of the screen, the stripe on the density mirror and the fringe of the screen can be diffracted to reflect a clear diamond shape. The upper and lower ends of the diamond pointed corner are shown. The scale of the screen is the mesh number. The density mirror now detects a 500 mesh screen.

nylon mesh sieve is important for those who need to detect or purchase. So you can use the above methods to help everyone better choose.
