The new concept of modern electrostatic prevention
Most of the previous anti-static technologies adhered to the following three principles: suppression, grooming, and neutralization, because it is generally considered that it is impossible to completely prevent static electricity generation. It can only suppress the accumulation of static charges, such as strictly limiting the transmission speed and personnel of logistics. The speed of operation, the equipment pipeline is as smooth and flat as possible, avoiding the appearance of corners and the like. If it can't be suppressed, try to divert it to the earth. If the air in the workplace is humidified, ground all the conductors, and place static conductive materials on the workbench and the ground. The operators wear static clothing and shoes and socks, even with static electricity. Hand ring and so on. If you can't get around, try to neutralize in situ, such as inductive consumers, high-voltage static consumers, ion wind consumers.
Although some measures have been taken to eliminate static electricity and have achieved certain effects, but the electrostatic hazard has not been completely eliminated. After years of analysis and application of various antistatic means and their effects, people finally realize that those methods are still local control, total Areas that are not protected by preventive measures may present an electrostatic hazard. So people imagined whether they can find a comprehensive environmental protection method. The answer is yes, this is the new concept of modern electrostatic prevention and control.
Different from the traditional concept of static electricity prevention, the all-round environmental protection of static electricity is no longer a specific static electricity generating part or working surface, but the entire space of the entire working area. The core is to eliminate all equipment. , materials, personnel in all aspects of the work process due to flow friction caused by the possibility of static electricity accumulation. This new concept has become the guiding principle for the prevention of static hazards in modern industrial and office automation and home electronics.
According to this guiding principle, the following key technologies must be developed to achieve all-round environmental protection:
1. Take appropriate measures on the ground, walls and ceilings in a relatively closed production or working environment to have good static conductivity.
2. Take surface treatment measures for all equipment countertops, etc., to effectively change the surface impedance of various materials so that they do not generate static electricity or static charges when they are subjected to friction.
3. Take comprehensive anti-static protection for the operation or staff in the environment to minimize the static electricity of the human body.
The antistatic measures taken above should not be related to the relative humidity of the ambient air or the space of the environment should be increased to increase the static conductivity of the air.
