Copper Wire Mesh Used to Shield Mobile Phone Signal
Copper mesh is divided into: copper mesh, brass mesh, phosphor copper mesh, these three kinds of copper mesh can play a shielding effect, but the shielding effect of copper mesh is a better product because the copper content of copper mesh is 99.99%. The copper mesh ranges from 2 to 200 mesh.
Main functions
1: Electromagnetic radiation protection, effectively blocking the damage of electromagnetic waves to the human body.
2: Shield electromagnetic interference and ensure the normal operation of equipment.
3: Prevent electromagnetic leakage and effectively shield the electromagnetic signal of the display window.
Main usage:
1: Electromagnetic shielding or electromagnetic radiation protection that needs light transmission; such as instrument display window shielding.
2: Electromagnetic shielding or electromagnetic radiation protection parts that need ventilation; such as chassis, cabinets, ventilation windows, etc.
3: Electromagnetic shielding or electromagnetic wave radiation of walls, floors, ceilings, etc.; such as laboratories, computer rooms, strong and weak current rooms, and radar stations.
4: Wire and cable, anti-electromagnetic interference, play a protective role in electromagnetic shielding.
Technical Parameters:
Light transmittance 50%-70%
Light transmission: low reflection, high light transmittance and good shielding performance.
Air permeability: good air permeability, and does not affect lighting.
Processing type: soft texture, good extensibility, easy to cut into different shapes and sizes, not drawn.
1, brass wire mesh
Raw materials: brass wire, 65 brass (about 65% copper, 35% zinc), 80 brass (about 80% copper, 20% zinc), etc.;
Mesh: 6 mesh/inch--160/inch for plain weave, 280 mesh for twill weave.
Features:
Brass wire mesh has appropriate tensile and extensibility, the smaller the number of meshes, the larger the mesh, the better the water filtration performance.
2, Copper wire mesh -- also known as shielding mesh
Raw material: copper wire (99.999% pure copper content)
Features: Copper wire mesh has good electrical conductivity, heat transfer performance, non-magnetic, anti-corrosion, wear-resistant.
Mesh: plain weave 5 mesh - 200 mesh, twill weave up to 250 mesh.
Uses: Filtering electron beams, electronic display screens, shielding electromagnetic wave signals.
3, Phosphor copper wire mesh
Raw materials: phosphor copper wire (85%-90% copper, 5%-15% zinc)
Features: non-magnetic, wear-resistant, acid and alkali resistant, good extensibility.
Mesh: 5-185 mesh for plain weave, 400 mesh for twill weave.
Uses: Usually used for printing and dyeing objects of powder, ceramic clay and glass, ceramics and filtering liquid and gas.
