1. Firstly, the total area (or number of blocks) of the anti-static floor required for computer room construction and the number of various accessories (standard ratio 1:3.5, 1:5.5) need to be accurately established, and a margin is left to avoid wastage. Or shortage. 2. To fully understand the variety and quality of anti-static floor produced by the manufacturer, 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. Place the whole piece of anti-static floor on the spliced ​​truss beam. After leveling the anti-static floor, the load-bearing capacity should reach a uniform load greater than 1000 kg/m2, and the concentrated load on any part of the anti-static floor should be greater than 300 kg. 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, electrostatic voltage, and surface resistance. The system resistance should be 10 5 Ω -10 8 Ω. 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 should be 10 5 Ω - 10 8 . Ω. 3. The load of the anti-static floor shall be determined based on the weight of the heaviest equipment among all equipments in the equipment room, so as to prevent the permanent deformation or damage of the floor caused by the overweight of some equipments. 4. The anti-static floor is less affected by external environmental conditions. That is, there will not be significant expansion and contraction due to the excessively high or low ambient temperature. That is, when the temperature of the equipment room is slightly high, the anti-static floor will expand and expand, and it cannot be removed or replaced. When the temperature is low, the anti-static floor will shrink and loosen. 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.
Carbon Crystal Heater is in the microcrystalline particles by adding far infrared emitters and temperature limiting agent with a special process and preparation technology made.it has good performance in Insulation resistance and flame retardant. When the carbon crystal heater is electrified, it will produce heat in 3-4 minutes. After 3-5 minute, you will feel suitable temperature. The application of the Carbon Crystal Electric Heater has saved the energy and reduced heating coats to a large degree.It's not only warm your room, but also decorate your room.
