Selection and precautions of anti-static workbench
There are many types of workbenches with special purposes. Everyone is not unfamiliar with antistatic workbenches. It is a workbench with antistatic function and is widely used in industrial workshops. That's because it has a wide range of uses, and its performance and advantages are very obvious compared with ordinary workbenches. So, what should you pay attention to when choosing a suitable antistatic workbench? Let's analyze it today.
1. The total area (or number of blocks) and various accessories (standard ratio 1:3.5, 1:5.5) required for the construction of the computer room and the amount of various accessories (standard ratio 1:3.5, 1:5.5) need to be accurately determined, so as to avoid waste Or shortage;
2. Understand the quality of the anti-static workbench produced by the manufacturer, and various technical performance indicators. Including mechanical properties and electrical properties. The mechanical properties mainly consider its bearing capacity and wear resistance. Install the whole anti-static workbench on the truss beams, after leveling the anti-static workbench, its load-bearing capacity should reach a uniform load greater than 1000kg/m2, and the concentrated load on any part of the antistatic workbench should be greater than 300kg When the load point with a diameter of 6cm bears a load of 300kg, 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 abrasion resistance. The electrical properties are mainly system resistance, electrostatic voltage, and surface resistance. The system resistance should be 105Ω-108Ω. When the temperature is 21±1.5°C and the relative humidity is 30%, the static voltage of the anti-static workbench should be lower than 2500V, and the surface resistance value should be 105Ω-108Ω;
3. Determine the load of the anti-static workbench based on the weight of the heaviest equipment in the equipment room, which can prevent some equipment from being too heavy and causing permanent deformation or damage to the floor;
4. It should be noted that the anti-static workbench is less affected by the external environmental conditions, that is, there will be no obvious expansion and contraction due to the high and low external temperature, that is, the anti-static workbench will expand and expand when the temperature in the machine room is slightly higher. It cannot be removed and replaced; the anti-static workbench shrinks when the temperature is low, resulting in a loose feeling. The shrinkage of the anti-static workbench under the influence of the environment should be less than 0.5mm, and the deflection of the board surface should be less than 0.25mm;
5. It is necessary to pay attention to the surface of the belt conveyor line of the anti-static workbench, which should be non-reflective, non-slip, corrosion-resistant, dust-free, dust-free, and easy to clean.
Through the above introduction, you have some understanding of the anti-static workbench. In the future, when you use the anti-static workbench, you should choose to use the anti-static workbench according to these characteristics. All in all, with the development of the domestic logistics industry today, how to prevent static electricity has become a topic of concern to major companies. Now, to cater to the consumer demand of the market and the needs of users, a series of anti-static workbenches have been developed to successfully complete The whole process of production and circulation in logistics operations.
