How does conductive silicone work

There are three ways to weaken interference waves: shielding, absorbing and filtering. Conductive rubber due to its conductive particles,

according to foreign scholars found. Electrons in the process of motion, can produce the opposite of the external magnetic field, play

a shielding role. But the principle of absorbing waves is similar to shielding, which also uses microscopic particles. When the filled

conductive particles reach the nanometer level, not only the particle size is nm, but more importantly, with a higher specific surface

area and porosity, such nanoparticles will have a better nano effect, and the nano effect can have a wave absorption effect. It is a

conductive rubber filled with conductive particles, which can play the role of shielding and absorbing wave. The volume resistance

may only reflect the size of the shield from a certain side, but it cannot measure the size of the absorption capacity. Although the

conductive rubber filled with conductive carbon black has large volume resistance, it can have the function of absorbing wave

because of its nano particle size and nano effect. Therefore, I will also see the rubber filled with carbon black as a seal on the microwave

oven. The magnetic field strength of the microwave oven is particularly large, up to 14G or more, and the rubber filled with carbon black

can better weaken the magnetic field wave.

When there is only a voltage drop, it depends on the relationship between current, voltage and resistance. There will always be a

certain current flow, but the current is too small, people can not feel the volume resistance of conductive rubber relative to the

metal is still very large, according to the relationship between the volume resistance and the distance is inversely proportional, the longer

the distance, the greater the resistance value. Medical electrodes, conductive rubber has been widely used, at this time the conductive

rubber electrode is thin, generally less than 1mm, the electrode is only the upper and lower two sides contact, that is, the distance is only

1mm when the conductive rubber is fully powered in daily life, it is possible to cut off a small piece of conductive rubber to repair the

position of the electrical contact head like the remote control. For the iron sheet like the battery electrode of the remote control is easy

to be corroded, if you replace the electrode with a conductive rubber sheet, one will not rust, two can be waterproof, three replacement

is also convenient, it is a good choice. What the author mentioned is only a conductive rubber filled with conductive carbon black, and

the volume resistance can be used in daily life in the range of several hundred ohms.
