Anti-static flooring, also known as static dissipative flooring, is a specialized flooring used to prevent electrostatic hazards. It is primarily used in computer rooms, data processing centers, microelectronics industries, and military and flammable/explosive environments, and has expanded to include bank computer rooms, telecommunications equipment rooms, microelectronics production workshops, biomedicine, laboratories, operating rooms, and other areas requiring strict static control.
When in use, it requires grounding and a protective resistor box. Technical specifications must comply with the "GB/T36340-2018 General Specifications for Anti-static Raised Floors" and "Conditions for Anti-static Flooring for Computer Rooms" standards. The surface resistance range is 1×10⁴～1×10⁶Ω for conductive type and 1×10⁶～1.0×10⁹Ω for static dissipative type. Materials include steel base, aluminum alloy base, composite base, wood base, and calcium sulfate base. Surface covering materials include environmentally friendly and wear-resistant materials such as ceramic, HPL, and PVC. Some products use recyclable base materials and low-VOC coating processes.
This flooring is divided into direct-laid and raised types: direct-laid types include anti-static tiles, PVC flooring, and floor coatings; raised types consist of a raised structure composed of base material and surface covering material. The system includes flooring, beams, and supports. Support types include standard, reinforced, and super-reinforced, with special-purpose supports including ramps and edging types.
