Second, before purchase, it is necessary to fully understand the type and quality of anti-static flooring produced by anti-static flooring nail manufacturers and various technical performance indicators. Specific detailed indicators can refer to the following parameters.
The technical performance of anti-static flooring mainly refers to its mechanical properties and conductive properties. The mechanical properties mainly consider its bearing capacity and wear resistance. Place the whole piece of anti-static floor on the spliced ​​truss beam. After placing the anti-static floor flat, the load-bearing capacity should reach a uniform load of more than 1000 kg/m2, and the concentrated load on any part of the anti-static floor should be greater than 300 kg at the diameter. For a 6-cm load point with a load of 300 kg, the deflection should be less than 2 mm and there should be no permanent deformation.
Adjustable support should be able to withstand more than 1000kg of vertical load, and the board should have a certain degree of abrasion resistance. The 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 static voltage of the antistatic floor should be lower than 2500V, and the surface resistance value should be 106Ω-109Ω.
3. The load of the anti-static floor shall be determined based on the weight of the heaviest equipment among all the equipment in the equipment room, so as to prevent the permanent deformation or damage of the floor caused by the overweight of some equipment.
Fourth, the change of the anti-static floor of Starlight by the external environmental conditions is very small. It will not be caused by the external environment temperature is too high, too low and significant expansion or deformation, that is, when the room temperature is slightly higher, the anti-static floor expansion and expansion, can not be removed and replaced; anti-static floor shrinks when the temperature is low, Create a sense of looseness. The amount of shrinkage of the antistatic 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 anti-static floor should not be reflective, slippery, corrosion-resistant, dust-free, dust-free, and easy to clean.
Anti-static floor selection method
First, the total area (or number of pieces) of the anti-static floor required for the construction of special places such as computer rooms, and the number of various accessories (standard ratios 1:3.5, 1:5.2) must be accurately established, and a margin must be reserved. So as not to cause waste or shortage.
