Antistatic flooring, also known as a static static electricity board, is a floor that, when grounded or connected to any lower potential, allows the charge to dissipate, with a resistance of 10 to 10 Ohm is characterized by.
Pick the method
1, the first need to accurately calculate the total number of anti-static floor of the building room (or block) and a variety of accessories (standard ratio of 1: 3.5.1: 5.2), and leave a margin, so as to avoid waste Or shortage.
2, fully understand the manufacturers of anti-static flooring produced by the variety and quality, and a variety of technical performance indicators.
The technical performance of anti-static floor mainly refers to its mechanical properties and electrical properties. Mechanical properties of the main consideration of its carrying capacity, wear resistance. Install the whole anti-static floor on the overlapped truss beam, flat anti-static floor, the carrying capacity should reach a uniform load greater than 1000kg / m2, anti-static floor on any part of the centralized load should be greater than 300kg, 6cm load point load on the load of 300kg, the deflection should be less than 2mm, no permanent deformation.
Adjustable support should be able to withstand more than 1000kg vertical load, and the board should have a certain degree of wear resistance. Electrical performance is mainly the system resistance, surface resistance. The system resistance should be 106Ω-109Ω, at a temperature of 21 ± 1.5 ℃, relative humidity of 30%, anti-static floor, the electrostatic voltage should be lower than 2500V, the surface resistance should be 106Ω-109Ω.
3, should be the engine room all the equipment in the heaviest equipment on the basis of the weight to determine the anti-static floor load, which can prevent some of the equipment caused by excessive deformation of the floor or damage.
4, anti-static floor by the impact of external environmental conditions change small. That is, because the ambient temperature is too high, too low a significant expansion and contraction, that is, when the engine room temperature is slightly higher, anti-static floor expansion expansion, can not be removed and replaced; low temperature anti-static floor shrinkage, resulting in loose feeling. Anti-static floor by the environmental impact of shrinkage should be less than 0.5mm, plate deflection should be less than 0.25mm.
5, anti-static floor surface should not reflect, do not slip, corrosion-resistant, dust-free, no dust, easy to clean.
