Q:How to use metal shield?Can the shield contact with the shield

Many people do not understand the principle of electromagnetic shielding, as long as the use of metal to make a box, and then the box to the ground, it can play the role of electromagnetic shielding. Under the guidance of this concept, the result is failure

Q:Someone want to use 20 pieces of 2 meters long, 1.2 meters wide metal mesh to build a rectangular wall by coop.

Because reach the height of not less than 2 meters, so the metal net can set width, is placed sideways,

Q:Metal mesh and metal shielding electromagnetic wave effect? Why?

Under the action of electromagnetic wave, the induced current is weak, according to Lenz's theorem, the ability to resist electromagnetic wave is small.

Q:The metal mesh can shield the electric field; electricity and magnetism have some similar characteristics

That is, the earth will not absorb the energy, so the metal mesh can not shield the magnetic field of the magnet, and the electric field is the change of the magnetic field, the magnetic field and the metal network to produce a relative...

Q:Microwave oven outer glass broke (inside the layer of metal mesh with the glass, because no matter) repair shop glass replacement, but I can find a suitable size of stainless steel plate, can replace it, if there is an adverse impact? Or do you have other solutions? Thank you1, the microwave oven door (Matsushita GM331H) has 2 layers of glass, tempered glass dust in the outer layer with metal net, the glass intact.2, tempered glass can not be cut, are to be customized to the glass factory, a small glass of people do not take orders and expensive.3, the inner layer with metal screen glass has been shielding microwave? Is the outer glass just a decorative effect?

You can use the stainless steel plate instead of the outside of the toughened glass, but the steel plate is opaque, can't see the food inside, overflow pot don't know. Can only deal with the use of.

Q:Room due to radiation problems, the need for transformation, please master pointing

For example, the wavelength of 1GHz is 0.3m, then the hole is less than 0.3/20=1.5cm can be a good shield (that is, no electromagnetic leakage).

Q:Metal mesh GF2W0.63/0.20 what does it mean?

The standard name is "industrial wire woven square hole screen"

Q:Fan net cover fan net cover metal mesh cover in what place

But also to prevent people close to the effect of inhalation injury.For air conditioning, motor, exhaust fan, radiator, fan, generator, diesel engine and other parts of the heat, exhaust and vent protection.

Q:Also, if the connection, the line order how ah! Thank you！

USB shielded wire mesh and the inside of the wire is not connected.The shielding wire is connected with other ground wires

Q:Melt flow through the metal mesh or rotating disc after the fall into small particles in the coolant, how to ensure that it is not a metal wire, but granule? How to ensure the screen is not blocked? How to ensure the metal in the air is not to lose the original characteristics of the metal oxide? These are the problems need to be solved.

As long as the temperature of the melt is sufficiently high, the melt is always liquid3 can be filled with protective gas, such as helium and other rare gases
