Hello. 200 purposes belong to the better quality.
The shielding mesh is generally copper.
and brass, the quality of copper is better.
Shielding mesh is generally 40, 80, 100, 200 mesh.
Shielding nets are basically one meter wide.
There are many manufacturers of electromagnetic shielding nets, and it is best to send some samples to determine a good manufacturer.

In terms of material, brass mesh or copper mesh is generally used, because copper mesh has the highest copper content and is the purest, so the shielding signal is the best. The copper mesh is divided into 80 meshes, 100 meshes, 120 meshes, 200 meshes, etc., the higher the number of meshes, the better the shielding effect, and of course, the more expensive it is. Shielding signal copper mesh function.
1) Electromagnetic radiation protection, effectively blocking the harm of electromagnetic waves to the human body.
2) Shielding electromagnetic interference to ensure the normal operation of instruments and equipment.
3) Prevent electromagnetic leakage: Effectively shield and suppress electromagnetic signals through the display window.
Shielding signal copper mesh use.
a. It is used for electromagnetic shielding or electromagnetic radiation protection that requires light transmission; For example: the shielding of the instrument display window.
b. It is used for electromagnetic shielding or electromagnetic radiation protection that requires ventilation; For example: chassis, cabinets, ventilation windows, etc.
c. It is used for electromagnetic shielding or electromagnetic radiation protection of walls, floors, ceilings and other parts, such as laboratories, computer rooms, strong and weak current rooms, and radar stations.
d. Used for wires and cables, anti-electromagnetic interference, and play a protective role in electromagnetic shielding.
According to the shielding effect, the shielding signal copper mesh can be divided into national standard shielding standards and non-standard shielding standards, how to distinguish them? In general, the specifications of copper shielding mesh in the market are 80 mesh, 100 mesh, 120 mesh, 150 mesh, and 200 mesh wire diameter, corresponding to the conventional standard wire diameter.
Non-standard shielding net refers to the same kind of mesh such as 80 mesh then the actual mesh is 70 mesh - 75 mesh can not reach the actual number of mesh, according to the national standard standard, 80 mesh is positive, 80 mesh will not become more than 70 purposes, shielding effect can be guaranteed and according to the use value, the national standard standard in the weaving method and production process is much higher than the non-standard quality system.
In the use of the occasion, the choice of the number of shielded copper mesh is also very important, generally in the military, secret bases, high-rise conference rooms, museums, high-speed rail and other high-tech fields, generally choose 200 mesh shielding mesh, its shielding effect and service life can reach the maximum value of shielding effect and utilization value. In general, domestic, enterprises, families, and companies choose the range of 80-150 mesh. In addition to shielding mobile phone signals, shielding nets can also block wireless wifi and block wireless signals.

350 mesh is compared to the bull copper mesh that sells screens. There are a lot of them here in Wuxi.

The copper mesh is good because the entire wire can be shielded, and the magnetic ring can only be the terminal.

Hello: The shielding effect of copper mesh is better, and the selection of copper wire shielding mesh should pay attention to the following points of copper wire material: brass, copper.
The diameter of the copper wire.
The density of the grid is generally expressed by the number of meshes, generally 40, 80, 100 mesh, etc., copper mesh shielding mesh is generally used in laboratories, computer rooms and other places, the effect is very good, I hope it will help you, hope to adopt.
Supor's after-sales service is super poor, my induction cooker is broken, I can't find out the reason for the overhaul, I often ask you to replace the motherboard, the cost is more than half of the new product, and I dare not guarantee how long it will last, and finally I have to give up.
I think there should be someone in the LAN who uses ARP to spoof Trojan programs (such as: World of Warcraft, Audition and other number-stealing software, and some plug-ins have also maliciously loaded this program). >>>More
Give money or not? Give me the money and I'll get it for you remotely.
Set a password for wireless routing.
First of all, there needs to be a clear answer to the question:The induction cooker that is widely circulated on the Internet to charge mobile phones has indeed succeeded in doing so!!!However, the process is not by placing the mobile phone that supports wireless charging directly on the induction cooker, but by making a homemade coil to generate electromagnetic induction, and after a series of voltage reductions, the voltage is reduced to DC voltage and then the mobile phone is charged. >>>More
