Computer room anti-static floor
The static electricity in the equipment room of the communication equipment is mainly that two objects with different electrification sequences collect positive charges on one object after contact and separation by friction, collision, peeling, etc., and an equal amount of negative charges accumulate on the other object. Forming. This is because when two different objects are in close contact with each other, the escape energy of the outermost electrons is different, and the electrons escape from the object with smaller work function to the object with larger work function. In addition, conductor electrostatic induction, piezoelectric effect, electromagnetic radiation induction, etc. can also generate high electrostatic voltage.
The danger of static electricity in the computer room
Static electricity in the equipment room not only causes random failures, malfunctions or operational errors during computer operation, but may also cause breakdown and destruction of certain components such as CMOS, MOS circuits, and dual-level circuits. In addition, static electricity has a significant impact on the external equipment of the computer. A display device with a cathode ray tube, when subjected to static electricity, may cause image disorder and blurring. Static electricity can also cause malfunctions such as Modem, network card, and Fax, and the printer does not print properly.
The problem caused by static electricity is not only difficult for hardware personnel to detect, but sometimes software personnel mistakenly believe that it is a software failure, which causes work confusion. In addition, when static electricity is discharged through a human body to a computer or other device (so-called fire), when the energy reaches a certain level, it also gives people a feeling of electric shock (such as when there is a significant electric shock when touching a computer monitor or a chassis).
The basic principle
1. Suppress or reduce the generation of static charge in the equipment room and strictly control the static power supply.
2. Safe and reliable, eliminate the static charge generated in the machine room and avoid the accumulation of static charge. The electrostatic conductive material and the static dissipative material use the leakage method to make the static charge leak to the ground through a certain path within a certain period of time; The static eliminator is a neutralization method that causes the static charge accumulated on the object to attract the opposite charge in the air, which is neutralized and eliminated.
3. Maintain and inspect the anti-static facilities on a regular basis (such as one week).
