The role of mesh size and permeability of Screen Printing Mesh

The so-called mesh refers to the particle size or coarseness of the material, generally defined as how many mesh holes in an area of 1 inch x 1 inch, that is, the number of mesh holes of the screen, the material can pass through the mesh is defined as how many mesh, the higher the mesh number, the more holes. In addition to indicating the mesh of the screen, it is also used to indicate the particle size that can pass through the screen, the higher the mesh, the smaller the particle size, the standard sieve needs to cooperate with the standard vibrating sieve machine to accurately determine

Mesh number difference.

The so-called mesh refers to the particle size or coarseness of the material, generally defined as the number of holes in an area of 1 inch × 1 inch, that is, the number of holes in the screen, the material can pass the mesh that is defined as the number of mesh, the higher the mesh, the more holes. In addition to indicating the mesh of the screen, it is also used to indicate the particle size of the particles that can pass through the screen, the higher the mesh, the smaller the particle size, the standard sieve needs to cooperate with the standard vibrating sieve machine to accurately determine.

Powder particle size is called particle size. Because the particle shape is very complex, there are usually sieve size, sink size, equivalent volume size, equivalent surface area size and other methods of expression. The sieve size is the size of the holes through which the particles can pass, expressed as the number of holes in a 1" (25.4mm) wide screen, hence the name "mesh".


 The role of the permeability of Screen Printing Mesh.

Screen Printing Mesh permeability ensures that dust and dirt are effectively kept out of the equipment while at the same time ensuring that the equipment remains breathable under changing environmental conditions, thus avoiding the build-up of internal gases that can lead to increased pressure. The result is damage to the housing seal, making the internal sensitive electronic components suffer from the hazards of water and dust attack.


1、Balance pressure

All motor equipment enclosures working outdoors are subjected to temperature fluctuations as well as wind, rain and sunlight radiation. Once the dust has entered the closed housing, if not removed in time. It will have a corrosive effect on sensitive electronic equipment. Good breathability Screen Printing Mesh helps balance the pressure inside and outside the enclosure, preventing air and moisture from entering the interior of the enclosure through the seals and effectively protecting the integrity of the seals. The breathable product also accelerates the rate of moisture dispersion. This reduces the accumulation of moisture inside the case and quickly eliminates condensation on the surface of the display and other devices.


2、Battery ventilation

In order to prevent the accumulation of explosive and harmful gases inside the battery, Screen Printing Mesh with good air permeability can prevent the accumulation of gases by regulating the pressure. The role of Screen Printing Mesh with good air permeability in this case is equivalent to a mechanical safety valve. For many types of rechargeable batteries, such as file ion batteries, the heat generated by the battery during discharge and charging increases the pressure inside the battery compartment.
