1. 1. The total area (or number of blocks) of anti-static floor and the number of various accessories (standard ratio 1: 3.5, 1: 5.5) required for the construction of the computer room should be accurately determined, leaving a margin to avoid waste or shortage.
2. Fully understand the variety and quality of the anti-static floor produced by the manufacturer, as well as various technical performance indicators. The technical performance of antistatic floor mainly refers to its mechanical performance and electrical performance. Mechanical properties mainly consider its bearing capacity and wear resistance. Install the whole anti-static floor on the overlapping truss beams. After leveling the anti-static floor, its bearing capacity should be greater than 1000kg/m2, and the concentrated load of any part of the anti-static floor should be greater than 300kg. When the loading point with a diameter of 6cm bears a load of 300kg, the deflection should be less than 2mm without permanent deformation. The adjustable bracket should be able to bear the vertical load above 1000kg, and the board surface should have certain wear resistance. The electrical properties are mainly system resistance and surface resistance. The system resistance should be106Ω-109Ω. When the temperature is 2 1 1.5℃ and the relative humidity is 30%, the electrostatic voltage of the anti-static floor should be lower than 2500V, and the surface resistance value should be106 Ω-109 Ω.
3. The load of the anti-static floor should be determined according to the weight of the heaviest equipment in the machine room, so as to prevent the floor from being permanently deformed or damaged due to the overweight of some equipment.
4. Anti-static floor is less affected by external environmental conditions. That is, there will be no obvious expansion and contraction due to the temperature of the external environment, that is, if the temperature of the computer room is slightly higher, the anti-static floor will expand and cannot be removed and replaced; When the temperature is low, the anti-static floor shrinks, resulting in a loose feeling. The shrinkage rate of antistatic floor affected by environment should be less than 0.5 mm, and the deflection of floor should be less than 0.25 mm.
5, anti-static floor surface should be non-reflective, non-slip, corrosion-resistant, dust-free, dust-free, easy to clean.
