What is an anti-static floor? How to choose an anti-static floor?

What is an anti-static floor? Anti-static floor is also called a dissipative static floor. When it is grounded or connected to any lower potential point, the charge can be dissipated and the resistance is characterized by a 1.0x105-10Ω. How to choose an anti-static floor better, then how do we choose it when faced with many anti-static floors in the market? Let's take a closer look at it.
What is an anti-static floor? Anti-static floor is also called a dissipative static floor. When it is grounded or connected to any lower potential point, the charge can be dissipated and the resistance is characterized by a 1.0x105-10Ω. How to choose an anti-static floor better, then how do we choose it when faced with many anti-static floors in the market? Let's take a closer look at it.
        1. Firstly, the total area (or 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) must be accurately provided, and a margin should be left to avoid waste or 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 the anti-static floor mainly refers to its mechanical and electrical properties. Mechanical properties mainly consider its bearing capacity and wear resistance. Install the entire anti-static floor on the lapped girders. After flat anti-static floor, the load-carrying 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 300kg is loaded on the 6cm loading point, the deflection should be less than 2mm and there is no 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, anti-static floor surface should not reflect, no slip, corrosion resistance, no dust, no vacuum, easy to clean.
