1. Firstly, it is necessary to accurately calculate the total area (or the number of blocks) of anti-static floor required for the construction of the computer room and the number of various accessories (standard ratio 1:3.5, 1:5.2), and leave a margin to avoid waste. Or a shortage.
2. Fully understand the variety and quality of anti-static flooring produced by manufacturers, as well as various technical performance indicators.
The technical performance of anti-static flooring mainly refers to its mechanical and electrical properties. The mechanical properties mainly consider its bearing capacity and wear resistance. Install the entire anti-static floor on the lapped girders. After laying the anti-static floor, the load capacity should reach a uniform load greater than 1000kg/m2. The concentrated load on any part of the anti-static floor should be greater than 300kg. When the load of 300 kg is loaded at a loading point of 6 cm, the amount of deflection should be less than 2 mm without permanent deformation.
The adjustable support should be able to withstand a vertical load of more than 1000kg, and the board surface should have a certain degree of abrasion resistance. Electrical properties are mainly system resistance and surface resistance. The system resistance should be 106Ω-109Ω. When the temperature is 21±1.5°C and the relative humidity is 30%, the electrostatic voltage of the anti-static floor should be lower than 2500V, and the surface resistance should be 106Ω-109Ω.
3. The load of the anti-static floor should be determined based on the weight of the heaviest equipment in all equipment in the equipment room. This can prevent some equipment from being overweight and causing permanent deformation or damage to the floor.
4. The anti-static floor is subject to small changes due to the influence of external environmental conditions. That is to say, the external environment temperature is too high or too low, and the anti-static floor expands and expands, and cannot be removed and replaced; when the temperature is low, the anti-static floor shrinks and produces a loose feeling. The amount of shrinkage of the anti-static floor affected by the environment should be less than 0.5mm, and the deflection of the board surface should be less than 0.25mm.
5. The surface of the anti-static floor should be non-reflective, non-slip, corrosion-resistant, dust-free, dust-free, and easy to clean.
