Grid copper is not subject to corrosion and acid-base environment, has anti-magnetic properties, wear resistant. Produced mesh copper wire of different diameters and different mesh size, as well as two kinds of fabric woven - plain and twill. All these parameters are regulated by GOST 6613. It sets parameters for woven wire mesh with square mesh, is made of non-ferrous metals and their alloys.
Grids are used:
-for the separation of the grain size of splintered materials;
-for the filtration of liquids and gases;
-for control of different materials on the particle size by grinding and crushing.
In accordance with the mesh size and wire thickness, and in accordance with the method of weaving, each species is assigned a copper mesh number. Grid copper must be made of annealed wire. It allowed discoloration, but not allowed corrosive spots, scale, cracks, creases, marks broach affecting the size of the cells, broken wires (more than 10 mm in length) and cross-linked site.
Grid copper produced in accordance with GOST 6613 has a certain diameter of the wire and the nominal size of the cells in the world, as well as specified deviation on these parameters, strictly in accordance with the rules of the standard. This standard regulates the width of each of the types of mesh and a minimum segment length.
Used mesh copper in electronics and instrumentation as screens for highly sensitive instruments and devices that protect from the effects of electromagnetic waves. Sometimes copper grid is set for the entire screening rooms for the staff in hazardous industries. Often, copper mesh screening in order to replace a copper plate or sheet and, though inferior to them in the density is much lighter in weight and price. An important factor is the ability of copper mesh breathable, water and light - often it is these properties are a priority.
