When purchasing anti-static raised floor, you should pay attention to the following points:
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. The whole piece of anti-static floor is installed on the spliced ​​truss beam. After the anti-static floor is leveled, its 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. When the loading point of 6cm is loaded with a load of 300kg, the amount of deflection should be less than 2mm and there should be no permanent deformation. Adjustable supports 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 should be 106Ω-109Ω.
3. The load of the anti-static floor should be determined based on the weight of the heaviest equipment among all the equipment in the equipment room. This can prevent some equipment from being heavy and cause permanent deformation or damage of the floor.
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 high or low temperature of the external environment. 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 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 be reflective, non-skid, corrosion-resistant, can not afford dust, not vacuuming, easy to clean.

The main purpose of the kitchen sink is to wash food, wash dishes, etc. According to the style, it can be divided into Apron Sink, workstation, Topmount Sink, Undermount Sink and so on. The sink is mainly made of 304 stainless steel, which is resistant to corrosion, oxidation, good toughness and durability.
