Anti-static floor also called dissipating floor is a floor, when it grounded or connected to any lower potential point, the charge can be dissipated to the resistance at 10 ^ 5 to 10 ohms 9 th among the features. "GB50174-2008 electronic information system room design specifications" states: anti-static floor or ground surface resistance or volume resistance should be 2.5 × l0 4 th to 9 th of 1.0 × 10 ohms. Scope industry sectors: anti-static elevated floor is mainly used in computer rooms, data processing centers, laboratories, microwave communications station room, program-controlled telephone switchboard room, Mobile Communications Equipment, satellite earth stations room, radio control room, TV transmitting station control room , broadcast control room, control room, central control room. Microelectronics industry: Static Control in the microelectronics industrial production has been widely used for electronic components, semiconductors, electronics assembly and large-scale, ultra large scale integrated circuit clean workshop, to avoid human motion to generate static electricity in the workshop. Control of electrostatic discharge on computer communications, various types of electronic equipment and hazardous electrostatic sensitive devices, computer memory and electronic equipment to prevent internal damage. Other applications: for inter-static sensitive arms, flammable and explosive places and petrochemical plant and hospital operating rooms, anesthesia rooms, oxygen bar and other anti-static requirements of the place. Acceptance criteria (1) below the floor surface and the floor should be clean and free of dust, artifacts; (2) the floor surface without scratches, no coating off, trim without damage; (3) Floor coverings firm as a whole should be stabilized personnel walking in the above sense should have shaken, there should be sound; (4) the edge of the floor should ensure a straight line, the adjacent floor dislocation of not more than 1mm; (5) the height of the adjacent floorboard is not more than 1mm.
