The raised floor is also called a dissipative static floor. When it is grounded or connected to any lower potential point, the charge can be dissipated, characterized by a resistance between 10 and 5 to 9 ohms.
The anti-static technology of the computer room is part of the security and protection of the computer room. Static electricity generated for a variety of reasons is one of the most frequent and difficult to eliminate. Static electricity not only causes random failures, malfunctions or operational errors in the operation of the computer, but also causes breakdown and destruction of certain components such as CMOS, MOS circuits, and two-stage 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 will also cause Modem, network card, Fax, etc. to work abnormally, and the printer's wiring is not smooth and other faults.
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 a feeling of electric shock.
