ESD Flooring By The Impact Of External Environmental Conditions Change Small
ESD Flooring selection method
1, the first need to accurately calculate the total number of ESD Flooring of the building room (or block number) and a variety of accessories (standard ratio 1: 3.5,1: 5.2), and leave a margin, so as to avoid waste Or shortage.
2, fully understand the manufacturers of ESD Flooringing produced by the variety and quality, and a variety of technical performance indicators.
The technical performance of ESD Flooring mainly refers to its mechanical properties and electrical properties. Mechanical properties of the main consideration of its carrying capacity, wear resistance. Install the whole ESD Flooring on the overlapped truss beam, flat ESD Flooring, the carrying capacity should reach a uniform load greater than 1000kg / m2, ESD Flooring 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%, ESD Flooring, 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 ESD Flooring load, which can prevent some of the equipment caused by excessive deformation of the floor or damage.
4, ESD Flooring 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, ESD Flooring expansion expansion, can not be removed and replaced; low temperature ESD Flooring shrinkage, resulting in loose feeling. ESD Flooring by the environmental impact of the amount of shrinkage should be less than 0.5mm, plate deflection should be less than 0.25mm.
5, ESD Flooring surface should not reflect, do not slip, corrosion-resistant, dust-free, no dust, easy to clean.
