  • 实验室内有静电怎么解决?

      一般来说,是不可能不产生静电,但有时只是静电产生并不足以造成伤害,真正的危险是静电的积累和由此产生的静电放电,因此防止静电的关键是如何使这些地方静电电压一直保持在一定的安全。今天将讨论如何有效防止实验室静电?什么是好的解决方案?
      Generally speaking, it is impossible not to generate static electricity, but sometimes static electricity is not enough to cause harm. The real danger is the accumulation of static electricity and the resulting electrostatic discharge. Therefore, the key to prevent static electricity is how to keep the electrostatic voltage in these places safe. VOLAB Wollebo's editor will discuss how to effectively prevent static electricity in the laboratory today. What is a good solution?
      电子仪器的生产过程,接地,静电泄露、耗散、中和、增湿、屏蔽等措施往往采取预防和抑制静电的产生和积累尽可能多的,或消除静电的积累迅速,安全,有效,以保护静电的破坏。
      In the production process of electronic instruments, measures such as grounding, electrostatic leakage, dissipation, neutralization, humidification and shielding are often taken to prevent and suppress the generation and accumulation of electrostatic as much as possible, or to eliminate the accumulation of electrostatic quickly, safely and effectively in order to protect the destruction of electrostatic.
      温湿度控制:
      Temperature and humidity control:
      从表中数据可以看出,环境湿度对人类活动产生的静电电压影响较大,静电防护区内相对环境湿度应控制在40%以上。当工艺条件允许时,可安装空调加湿器和喷雾器,以提高空气的相对湿度。
      From the data in the table, it can be seen that the environmental humidity has a great influence on the static voltage generated by human activities, and the relative environmental humidity in the electrostatic protection zone should be controlled at more than 40%. When the process conditions are allowed, air conditioning humidifiers and sprayers can be installed to improve the relative humidity of the air.
      此外,当绝对湿度恒定时,温度越高的区域相对湿度越低,因此保持较低的温度有利于静电防护。
      In addition, when the absolute humidity is constant, the higher the temperature, the lower the relative humidity in the area. Therefore, keeping a lower temperature is conducive to electrostatic protection.
      良好的接地系统:
      Good grounding system:
      防静电接地系统是接地泄漏的接地接入通道,是由地面、墙面、工作台、设备、仪表、腕带等工作区依次向地面引入接地费用的电气连接系统。
      Anti-static grounding system is a grounding access channel for grounding leakage. It is an electrical connection system that introduces grounding fees to the ground in turn from the working areas of ground, wall, worktable, equipment, instrument, wristband and so on.
    实验室装修
      为了有效防止静电的危害,需要在静电保护的环境中为所有导体(包括人员)提供通道,使静电能够在较短的时间(如0.1秒)内及时、安全的排出。可靠的接地提供了“等电位”效应,有效地减少静电对静电敏感器件的损害。
      In order to effectively prevent the harm of static electricity, it is necessary to provide channels for all conductors (including personnel) in the environment of static electricity protection, so that static electricity can be discharged in a short time (such as 0.1 seconds) in a timely and safe manner. Reliable grounding provides "equipotential" effect, which effectively reduces the damage of static electricity to electrostatic sensitive devices.
      总之,所有与设备接触的物体,包括空间,都应采取防静电措施,形成完整的静电保护区。
      In short, all objects in contact with equipment, including space, should take anti-static measures to form a complete electrostatic protection area.
      系统必须独立、可靠的接地装置接地电阻应小于10欧姆(防静电地面不得承担零线的力量,不得与防雷接地,如使用三相五线制供电,可以用作测地线防静电地面,但零线,地面不得混合)接地面积应小于100,是一个主干横截面积应小于6,设备与工作台的接地线应采用横截面积不小于1.25被多股采用塑料线接地线颜色以绿色和黄色为主接线方式宜采用钎焊。实验室专用埋地导线如图所示。专用地线应埋在建筑物潮湿的一侧,地线可长600~700mm宽400~500mm厚4~5mm的铜板上,并在铜板上钎焊引线;横截面积不小于100mm2 <组成的扁铜线。
      The grounding resistance of the independent and reliable grounding device of the system should be less than 10 ohms (the anti-static ground should not bear the force of zero line, and should not be grounded with lightning protection. If the three-phase five-wire system is used for power supply, it can be used as the anti-static ground of the geodesic line, but the zero line and the ground should not be mixed). The grounding area should be less than 100, and the cross-sectional area of a trunk should be less than 6, and the grounding line of the equipment and the worktable should be used No less than 1.25 by multiple strands using plastic grounding wire color green and yellow as the main wiring mode should be brazed. The underground conductors for laboratory use are shown in the figure. The special ground wire should be buried on the damp side of the building. The ground wire can be 600-700 mm long, 400-500 mm wide and 4-5 mm thick. The lead wire should be brazed on the copper plate. The cross-section area of the flat copper wire should not be less than 100 mm2 <
